Q

What is the Swiss Cheese Model?

A

holes = opportunities for a process to fail. Some are active faliures, some are due to latent conditions.
slices = “defensive layers” against potential error impacting the outcome
For an error to occur, successive layers of barriers, defences and safeguards need to be breeched

Q

What are some benefits of systematic reviews?

A
  • Help address clinical uncertainty
  • Highlight gaps in research
  • Appraise and integrate findings, meaning that quality is controlled so we can be more certain of our findings
  • Offer authoritative, up-to-date and generalizable conclusions
  • Save clinicians from having to locate and appraise studies for themselves
  • Reduce delay between research discoveries and implementation
  • Help to prevent biased decisions
  • Easily converted into guidelines and recommendations

Q

What are some practical criticisms of evidence based medicine?

A
  • Creating and maintaining systematic reviews across all specialities may be an impossible task
  • Disseminating and implementing the findings may be challenging and expensive
  • RCTs are not always feasible
  • The outcomes considered are often biomedical, of little importance to patients, as well as limiting the interventions which can be trialled
  • Pharmaceutical companies need to be trusted about the quality of their RCTs

Q

What are some philosophical criticisms of evidence based medicine?

A
  • Doctors want to know the mechanism of an outcome = deterministic causality, whereas EBP only shows what the outcome is = probabilistic causality.
  • Population level outcomes do not mean that an intervention will work for the individual
  • Potential for the creation of unreflective rule followers who do not consider patients as individuals due to NICE and clinical governance.
  • Could be used as a means of legitimising rationing, but just because a treatment is not cost-effective at a population level does not mean it is not effective to an individual patient.
  • The loss of professional responsibility and autonomy as clinical judgement is no longer as needed.

25
Give some methods of quantitative research
``` RCT Cohort studies Case-control studies Cross-sectional surveys Official statistics Surveys – national, regional or local ```
26
Define valid
using an appropriate method to measure what you are trying to measure
27
Define reliable
measuring consistently
28
How can the validity and reliability of a questionnaire be ensured?
using a published questionnaire
29
What advantages do quantitative methods have?
finding relationships | allowing comparisons
30
What are the disadvantages of quantitative methods?
forces people into inappropriate categories doesn't allow people to express things in the way they want to all important information may not be accessed may not be able to establish causality
31
What is qualitative research?
Aims to make sense of phenomena in terms of the meanings that people bring to them. emphasises meaning, experience and views of the respondents. Analysis emphasises the interpretations of the researcher. The findings can also provide insights into people’s behaviour.
32
Give some methods of qualitative research
observation and ethnography interviews focus groups documentary and media analysis
33
Describe observation used in qualitative research
Studying human behaviour in its natural context, observing what people actually do Gains access to behaviour that individuals themselves may provide biased accounts of, be unaware of or not consider worth commenting on
34
Describe interviews used in qualitative research
Semi-structured by using a prompt guide. There is a clear agenda of topics. There is an emphasis on participants giving their own perspective, which the interviewer facilitates
35
Describe focus groups used in qualitative research
quick method for defining the scope of a particular problem or for accessing group based collective understanding of an issue. Not so useful in understanding individual experience as deviant views mat be inhibited and some topics may be too sensitive for focus groups Difficult to arrange as a fairly homogenous group is needed and a good facilitator who can manage the group dynamics
36
Describe documentary and media analysis used in qualitative research
Independent evidence eg. patient diaries Provides a historical context Useful for subjects difficult to investigate
37
What are the advantages of qualitative research?
gain an understanding of people's perspectives access information that cannot be reached by quantitative research explain relationships between variables
38
What are the disadvantages of qualitative research?
difficult to find consistent relationships between variables | samples often not statistically representative, so findings cannot be generalised
39
Why do deprived groups have higher use rates of GP and emergency services?
Health is managed as a series of crises, with health care only accessed when things become a problem Ill health becoming normalised. People accept ill health rather than trying to do something about it Event-based consulting required to legitimise a consultation, so the patient will only access health services when there is clearly something wrong Difficulty marshalling resources needed for negotiation and engagement with health services e.g. employment, childcare, getting to the surgery Tendency to use more ‘porous’ services Lack of cultural alignment between health services and lower socioeconomic status Doctor’s judgement of a patient’s technical and social eligibility may affect referrals and offers of healthcare
40
What is the Artefact explanation for health inequalities? What is a limitation of this explanation?
health inequalities are evident because of the way statistics are collected They are not really there! data problems would lead to an underestimation of inequalities
41
What is the Social Selection explanation for health inequalities? What is a limitation of this explanation?
a person's health status leads to their social position Chronically ill and disabled are more likely to be disadvantaged diseases that take longer to kill would be more prevalent in lower socioeconomic groups
42
What is the Behavioural-Cultural explanation for health inequalities? What is a limitation of this explanation?
ill health is due to people's decisions, knowledge and goals People from disadvantaged backgrounds tend to engage in more health damaging behaviours, while people from advantaged backgrounds tend to engage in more health-promoting behaviours in adverse conditions, decisions may be difficult to exercise choices may not be available for those whose lives are constrained by a lack of resources
43
What is the Materialist explanation for health inequalities? What is a limitation of this explanation?
inequalities arise form differential access to material resources and exposure to hazards or constraints (income, environment, occupation, housing). People have a lack of choice in what factors they are exposed to. Accumulations of factors over lifetime further research is needed to determine the precise routes through which material deprivation causes ill health
44
What is the Psychosocial explanation for health inequalities?
Stressors (negative life events, social support, job security) are distributed on a social gradient stress impacts on health directly and indirectly
45
What is the Income Distribution explanation for health inequalities? What is a limitation of this explanation?
Relative income affects health. Countries with greater income inequalities have greater health inequalities. It is the most egalitarian societies that have the best health Social cohesion is important for health
46
Define inequality
when things are not equal
47
Define inequity
inequality that is unfair or unavoidable
48
Define a lay belief
how people understand and make sense of health and illness constructed by people with no specialised knowledge they are socially embedded and very complex draw on cultural, social and personal knowledge and experience and a patient’s own biography
49
Define health behaviour
activity undertaken for the purpose of maintaining health and preventing illness
50
Define illness behaviour
activity of ill person to define illness and seek solution
51
What is the illness/symptom iceberg?
most symptoms experienced by patients will never be known by a doctor
52
What is the lay referral system ?
chain of advice seeking contacts which the sick make with other lay people prior to – or instead of – seeking help from health care professionals.
53
What is the negative definition of health? What demographic is this definition most common in?
health = the absence of illness | Most common in low SE groups
54
What is the Functional definition of health? What demographic is this definition most common in?
health = the ability to do certain things. | Most common in the elderly
55
What is the positive definition of health? What demographic is this definition most common in?
health = state of wellbeing and fitness. | Most common in high SE
56
In terms of adherence, describe a denier Do these people adhere to treatment?
= those who deny they have a condition/having the ‘proper’ disease. claim that their symptoms do not interfere with their everyday life use complex and drastic strategies to hide their disease. T they will not adhere to their treatment, due to not accepting their disease identity
57
In terms of adherence, describe an acceptor Do these people adhere to treatment?
= those who accept their disease diagnosis and doctor’s advice completely. Yes! They take control of their symptoms through medication and do not see their disease identity as a stigma.
58
In terms of adherence, describe a pragmatist Do these people adhere to treatment?
= those who use preventative treatment, but only when their symptoms get very bad. See their disease as a mild illness.
59
Which definition of health is useful in health promotion? Why?
A positive definition of health it looks at health as something that can be maintained and worked towards
60
Why are those from a lower socioeconomic group not follow health promotion advice?
focus is on improving the immediate environment
61
Why are those of a higher social class more likely to follow health promotion advice?
focused on long term investments
62
What are determinants of health?
a range of factors that have a powerful and cumulative effect on the health of populations, communities and individuals. Includes: physical environment social and economic environment individual genetics, characteristics and behaviours.
63
What is public health?
reform of physical environment to improve health
64
What is health education?
targeting individual health behaviour to improve health
65
What is health promotion?
the process of enabling people to increase control over and to improve their health
66
What are the principles of health promotion?
Empowering = enabling individuals and communities to assume more power over health determinants Participatory = Involving all concerned at all stages of the process Holistic = Fostering physical, mental, social and spiritual health Intersectoral = Agencies from relevant sectors collaborate Equitable Sustainable = changes that individuals and communities can maintain once funding has ended Multi-strategy
67
State the approaches to health promotion
Medical or preventative = encouraging people to seek help Behaviour change Educational Empowerment = a patient's health is their own responsibility Social change
68
What is primary prevention?
preventing the onset of disease or injury by reducing exposure to risk factors
69
State some primary prevention strategies
immunisation prevention of contact with environmental risk factors Taking appropriate precautions with communicable diseases Reducing risk factors from health related behaviours
70
What is secondary prevention?
to detect and treat a disease (or its risk factors) at an early stage prevents progression or potential complications and disabilities from the disease in the future
71
State some secondary prevention strategies
screening | monitoring
72
What is tertiary prevention?
minimises the effects of an established disease
73
State some tertiary prevention strategies
maximising remaining capabilities of a disabled patient giving steroids for asthma to prevent asthma attacks giving a renal transplant
74
How can health promotion lead to a neglect of public health?
the focus on individual responsibility
75
What are some dilemmas of health promotion?
``` interfering in people's lives victim blaming fallacy of empowerment reinforcing negative stereotypes unequal distribution of responsibility the prevention paradox ```
76
Explain how health promotion raises issues about the ethics of interfering in people's lives
potential psychological impact of health promotion messages leads to high levels of anxiety, especially if people cannot address the problem. The idea of a ‘Nanny State’ is also a worry – do people have a right to make their own choices?
77
Explain how health promotion raises issues of victim blaming
Focus on individual behavioural change plays down the impact of wider socioeconomic and environmental determinants on health
78
Explain how health promotion raises issues about the Fallacy of Empowerment
Giving people information does not give them power. Unhealthy lifestyles are not often due to ignorance but due to adverse circumstances and wider socioeconomic determinants of health.
79
Explain how health promotion raises issues of unequal distribution of responsibility
The implementation of healthy behaviours in the family is often left up to women
80
Explain how health promotion raises issues about the prevention paradox
Interventions that make a difference at a population level often have little effect at an individual level. If people don’t see themselves as a candidate for a disease they will not take on health promotion messages!
81
What is evaluation?
rigorous and systematic collection of data to assess the effectiveness of a programme in achieving predetermined objectives
82
Why is evaluation needed?
evidence based interventions can be found interventions are found to be legitimate = accountability it is ensured there is no direct or indirect harm = ethical programmes can be managed and developed
83
What is process evaluation?
assessing the process of programme implementation | Employs a wide range of mainly qualitative methods
84
What is impact evaluation?
assessing the immediate effects of an intervention
85
What is outcome evaluation?
measuring the longer term consequences. The timing of the evaluation can influence the outcome, for example there may be a delay (interventions take a long time to have an effect) or decay (some interventions wear off rapidly)
86
What are some difficulties of evaluation?
possible time lag to effect confounding factors high cost the intervention design makes it difficult to assess
87
Define illness narrative
the story-telling and accounting of practices that occur in the face of illness
88
What is illness work?
= work performed when getting a diagnosis, managing the symptoms of a chronic illness, dealing with the physical manifestations of the disease and must be done before being able to cope with social relationships.
89
What is everyday life work?
=managing daily living
90
Define coping
the cognitive processes involved in dealing with illness
91
Define strategy
the actions and processes involved in managing the condition and its impact
92
Describe the process of normalisation
A patient can choose to keep their pre-illness life style and identity intact by disguising or minimising their symptoms, or they can designate their new life as “normal life”. This would signal a change in identity, rather than preserving an old one.
93
What is emotional work?
= managing one’s own emotions and those of others. This is the work that people do to protect the emotional well-being of the people around them. Patients will make a conscious effort to deliberately maintain normal activities. If people do find friendships disrupted, it may be easier for them to withdraw or restrict their social terrain. Patients may downplay pain or other symptoms, presenting a ‘cheery version’ of themselves.
94
What is biographical work?
= reconstruction of biography. There is a biological shift from a perceived normal trajectory to an abnormal trajectory. A former self-image often crumbles away without the simultaneous development of equally valued new ones = loss of self. There is a constant struggle to lead a valued life and maintain a positive definition of self. Patients can often feel that their body is letting them down.
95
What is identity work?
= work to maintain an acceptable identity. This is the consequence of actual and imagined reactions of others. Illness can become a defining aspect of someone’s identity.
96
What are the advantages or self-management?
improving the patients coping skills improving condition management skills reducing hospital admissions more patient centred approach
97
What are the disadvantages or self-management?
difficult to achieve responsibility of care is placed on very ill patients, which may be difficult for the patient to cope with. little evidence of efficiency savings from this approach.
98
Define stigma
negatively defined condition, attribute, trait or behaviour conferring a deviant status.
99
What is discreditable stigma
nothing can be seen from the outside, BUT if it was found out there would be a problem. E.g. mental illness, HIV
100
What is discredited stigma?
physically visible characteristic or well-known stigma which sets a person apart e.g. physical disability, known suicide attempt
101
What is enacted stigma?
the real experience of prejudice, discrimination and disadvantage as the consequence of a condition
102
What is felt stigma?
the fear of enacted stigma. The feeling of shame associated with having a condition. This can lead to selective concealment.
103
Explain the Medical Model of Disability
Disability is a deviation from medical norms | disadvantages are a direct consequence of impairment. People are in need of medical interventions to cure of help them.
104
What are some limitations of the Medical Model of Disability?
lack of recognition of the social and psychological factors involved in disability use of stereotyping and stigmatising language.
105
Explain the Social Model of Disability
Problems are a product of the environment and failure of the environment to adjust. Disability is therefore a form of social oppression. Political action and social change are needed to overcome these problems. Society often fails to take account of people with impairments.
106
What are some limitations of the Social Model of Disability?
There may be a failure to recognise the bodily realities and the extent to which these are solvable socially.
107
According to the International Classification of Impairments, Disabilities or Handicaps, define: impairment disability handicap
-Impairment: concerned with abnormalities in the structure or functioning of body – Disability: concerned with performance of activities – Handicap: concerned with broader social and psychological consequences of living with impairment and disability
108
What are the limitations of the International Classification of Impairments, Disabilities or Handicaps?
problematic use of the word handicap. implies that problems are intrinsic or inevitable. based on the medical model of disability.
109
What is the International Classification of Functions, Disability and Health?
WHO's framework for measuring health and disability at both individual and population levels to describe and measure health and disability. It attempts to integrate medical and social models, and recognise significance of wider environment.
110
What are the components of the International Classification of Functions, Disability and Health?
Body structures and functions, and impairments Activities undertaken by individual, and the difficulties/limitations experienced in doing them Participation or involvement in life situations, which may become restricted Environmental and personal factors
111
Why are healthcare outcomes measured?
give an indication of the need for healthcare, target resources where they are most needed, assess the effectiveness of health interventions, evaluate the quality of health services, monitor patients’ progress use these evaluations to get better value for money.
112
Discuss the advantages of using mortality as a measure of healthcare outcomes
easily defined
113
Discuss the disadvantages of using mortality as a measure of healthcare outcomes
not always recorded accurately. | It is not a good way of assessing the outcomes and quality of care.
114
Discuss the advantages of using morbidity as a measure of healthcare outcomes
routinely collected
115
Discuss the disadvantages of using morbidity as a measure of healthcare outcomes
collection is not often reliable or accurate. We do not learn anything about patient’s experiences the data is not easy to use in evaluation
116
What are patient reported outcome measures?
attempt to assess well-being from the patient’s point of view. PROMs are measures of health that come directly from patients. They compare scores before and after treatment or over a longer period of time.
117
How can patient reported outcomes measures be used?
* clinically * to assess benefits in relation to cost * in clinical audit * to measure the health status of populations * to compare interventions in a clinical trial * as a measure of service quality
118
What are the benefits of using patient reported outcome measures?
improve the clinical management of patients allow for the comparison of providers, which increases their productivity by creating demand management improves care quality though patient choice, purchasing and payment for performance.
119
What are the challenges of using patient reported outcome measures?
* the time and cost of collection, analysis, and presentation of data * Achieving high rates of patient participation * Providing appropriate output to different audiences * Avoiding misuse of PROMs
120
Define Health Related Quality of Life
the functional effect of an illness and its consequent therapy upon a patient, as perceived by the patient’
121
What does HRQoL take into account?
• Physical function o Mobility, dexterity, range of movement, physical activity, activities of daily living • Symptoms o Pain, nausea, appetite, energy, vitality, fatigue, sleep, rest • Global judgements of health o What does the patient think health means? Shaped by society and culture • Psychological wellbeing o anxiety, depression, coping, positive well-being and adjustment, sense of control, self-esteem • Social wellbeing o Family and intimate relations, social contact, integration, social opportunities, leisure activities, sexual activity and satisfaction • Cognitive functioning o Cognition, alertness, concentration, memory, confusion, ability to communicate • Personal constructs o Satisfaction with bodily appearance, stigma, life satisfaction, spirituality • Satisfaction with care
122
What are the advantages of using a generic instrument to assess HRQoL?
Used for a broad range of health problems Used if there is no disease specific instrument Enable comparisons across treatment groups Used to detect unexpected effects of an intervention Used to assess the health of populations
123
What are the disadvantages of using a generic instrument to assess HRQoL?
Less detailed Loss of relevance if too general Less sensitive to changes that are a result of an intervention Less acceptable to patients
124
What is the SF-36?
``` a generic HRQoL measure It asks questions relating to eight dimensions: - Physical functioning - Social functioning - Role functioning (physical) - Role functioning (emotional) - Bodily pain - Vitality - General health - Mental health ``` Patient’s responses to the questions are scored and the scores for items within each dimension are added together. This score is transformed to give each respondent’s score for each dimension (0-100). You are NOT allowed to add up the dimensions to give an overall score
125
What are the advantages of using the SF-36 as a measure of HRQoL?
acceptable to the patients completing it. takes 5-10 minutes to complete. has a good internal consistency is responsive to change There is population level data available it has been well validated and tested for reliability.
126
What is the EuroQol EQ-5D?
``` generic HRQoL measure It generates a single index value for health status on which full health = 1 and death = 0. It assesses five dimensions: • Mobility • Self-care • Usual activities (e.g. work,study, housework, family or leisure activities) • Pain/Discomfort • Anxiety/Depression ``` Patients say whether they have no problems, moderate problems or extreme problems relating to each dimension.
127
What are the advantages of using the EuroQol EQ-5D as a measure of HRQoL?
widely used, good population data available, has been well validated and tested for reliability.
128
What are the advantages of using a disease/site/dimension specific instrument to assess HRQoL?
Relevant content Sensitive to change Acceptable to patients
129
What are the disadvantages of using a disease/site/dimension specific instrument to assess HRQoL?
Not able to be used in those who don’t have the disease Comparison is limited May not detect unexpected effects
130
How does disclosure improve quality of care?
Focus on safety, effectiveness and experience of patients
131
Define screening
a public health service members of a defined population, who do not necessarily perceive they are at risk of, or are already affected by a disease or its complications, are asked a question or offered a test, to identify those individuals who are more likely to be helped than harmed by further tests or treatment to reduce the risk of a disease or its complications
132
What criteria relating to the disease are used when implementing a screening programme?
an important health problem epidemiology and natural history is well understood an early detectable stage cost-effective primary prevention interventions must have already been considered and where possible implemented
133
What criteria relating to the test are used when implementing a screening programme?
simple, safe, precise, valid acceptable to the population. The distribution of test values in the population must be known i.e. the proportion who test positive and negative an agreed cut-off level for who is counted as test-positive must be defined. There must be an agreed policy on whom to investigate further.
134
Define a false-positive
non-cases who test positive
135
What are the problems involved with false positive results?
puts patients through stress, anxiety and inconvenience turns people into 'patients' when they are not actually ill creates direct costs and opportunity costs. may lead to lower uptake of screening in the future
136
Define a false-negative
cases who test negative People who do actually have an early form of the disease will fail to be referred
137
What are the problems involved with false negative results?
creates inappropriate reassurance may delay a patient’s presentation with symptoms patients not offered diagnostic testing when they could have benefited from their disease will not be diagnosed
138
What are the four measures of test validity?
sensitivity specificity positive predictive value negative predictive value
139
# Define sensitivity How is this calculated?
The proportion of people with the disease who are test positive true positives -------------------- true positives + false negatives first column
140
Describe the lay out of the screening calculation table
horizontal = disease present, disease absent vertical = positive test, negative test
141
If a test has a high sensitivity, what is it good at?
correctly identifying those with the disease
142
# Define specificity How is this calculated?
the proportion of the people without the disease who are test negative true negatives -------------------- false positives + true negatives second column
143
If a test has a high specificity, what is it good at?
correctly identifying people without the disease as not having the disease
144
If the same test is applied to a different population, what will happen to the sensitivity and specificity?
stay the same! they are a function of the characteristics of the test
145
# Define PPV How is this calculated?
the probability that someone who has tested positive actually has the disease True positives ------------------------ true positives + false negatives first row
146
What is the PPV influenced by?
prevalence low prevalence = low PPV
147
If a test has a low PPV, what does this mean?
there will be a lot of people with false positive results who undergo stress and unnecessary procedures
148
# Define NPV How is this calculated?
the proportion of the people who are test negative who actually do not have the disease true negative ------------------- false negative + true positive second row

What criteria relating to the treatment are used when implementing a screening programme?
There must be effective evidence based treatment available early treatment must be advantageous There must be an agreed policy on whom to treat. Clinical management of the condition and patient outcomes should be optimised in health care providers before participation in screening programme
150
What criteria relating to the programme are used when implementing a screening programme?
* Proven effectiveness (preferably with RCT data) * Quality assurance for the whole programme not just the test * Facilities for counselling * Facilities for diagnosis and treatment * Other options should be considered e.g. improving treatment * Think about opportunity costs * Decisions about parameters should be scientifically justifiable to the public * Benefit should outweigh physical and psychological harm (test, diagnostic procedures or treatment)
151
How does lead time bias occur when evaluating screening programmes?
Early diagnosis falsely appears to prolong survival because screened patients appear to survive longer. However this is only because they were diagnosed earlier. Patients live the same length of time, but longer knowing they have the disease.
152
How does length time bias occur when evaluating screening programmes?
Screening programmes are, by design, better at picking up slow growing, unthreatening cases of a disease than aggressive, fast-growing cases. Therefore, diseases that are detectable through screening are more likely to have a favourable prognosis, and may indeed never have caused a problem in the future. This could lead to false conclusion that screening is beneficial in lengthening the lives of those found positive.
153
How does selection bias occur when evaluating screening programmes?
Studies of screening are often skewed by the ‘healthy volunteer’ effect. Those who have regular screening are also likely to do other things that protect them from disease.
154
How could screening alter the doctor-patient contract?
usually, people self-present asking for help, so define themselves as patients. screening targets apparently healthy people who have not sought the help of the health service with the offer of help for something they may have never thought about.
155
What are the limitations of screening?
Screening cannot offer a guarantee of protection. Screening carries a potential for harm as well as benefit. Due to false positives, screening leads to people being investigated and treated unnecessarily. The complexity of screening programmes can be unhelpful
156
Explain the structural critiques of screening
• Victim blaming Screening encourages individuals to take responsibility for their own health, however not all individuals are equally able to do this. • Individualising pathology This leads to professionals not addressing the underlying material causes of a disease
157
Explain the surveillance critiques of screening
Individuals and populations are increasingly subject to surveillance Prevention could be part of a wider apparatus of social control
158
Explain the social constructionist critiques of screening
• Health and illness practices can be seen as moral – people can gain meaning through particular social relationships
159
Explain the social feminist critiques of screening
is screening targeted more at women?
160
Who has an overall accountability for the NHS?
Secretary of State
161
What is the Department of Health's role?
sets national standards | sets national tariffs - fee for services charged by service providers to commissioners
162
What is the role of NHS England?
authorises Clinical Commissioning Groups supports develops and performance-manages commissioning . commissions specialist services and primary care
163
Who are the CCGs accountable to?
NHS England
164
What is the role of clinical commissioning groups?
commission secondary and community healthcare services
165
Who is responsible for public health?
local authorities
166
Where can care be commissioned from?
o NHS acute trusts (hospitals) for much acute care o Community healthcare trusts o Other providers, including the private sector
167
What are some examples of management roles for doctors?
o Medical director (overall responsibility for medical quality) o Clinical director (overall responsibility for directorate) o Consultant (responsibility for team) o General practitioner –practice principal or partner
168
What is the role of a clinical director?
leads a clinical directorate - group within a hospital trust • manage their directorate as a whole • provide continuing medical education and other training • design and implement directorate policies on junior doctors’ hours of work, supervision, tasks and responsibilities • Implement clinical audit • Develop management guidelines and protocols for clinical procedures • Induction of new doctors
169
What is the role of a medical director?
communicate between the board and the medical staff. Work in partnership with HR/personnel • Approve job descriptions, interview panels, equal opportunities and discretionary pay awards • Oversee disciplinary processes • Lead an organisation’s clinical policy and clinical standards • Have a strategic overview of medical staff’s role in the organisation • Sit on the organisation’s Board of Directors—a key link between senior management and the medical staff
170
What are some skills involved in management?
* Strategic - ability to analyse, plan, make decisions * Financial - ability to set priorities and manage a budget * Operational - ability to run things, execute plans * Human resources - ability to manage people and teams
171
Why is rationing inevitable?
the scarcity of resources means that demand outstrips supply
172
Explain the process of explicit rationing
There are defined rules of entitlement institutional procedures are used in the systematic allocation of resources Care is limited, but the decisions and reasons for this are made clear
173
What are the advantages of explicit rationing?
* Transparent, accountable * Opportunity for debate * More clearly evidence based * More opportunities for equity in decision making
174
What are the disadvantages of explicit rationing?
* Very complex * Heterogeneity of patients and illnesses not catered for * Patient and professional hostility * Impacts on clinical freedom * Some evidence of patient distress
175
Explain the process of implicit rationing
Care is limited, but neither the decisions, nor the bases for those decisions, are clearly expressed. The allocation of resources is through individual clinical decisions without the criteria for those decisions being explicit
176
What are the disadvantages of implicit rationing?
It can lead to inequities and discrimination | Decisions are based on perceptions of “social deservingness”
177
What are the advantages of implicit rationing?
more sensitive to the complexity of medical decisions | more sensitive to the needs and personal and cultural preferences of patients.
178
Why was NICE set up?
to enable the integration of clinical evidence and cost effectiveness to inform a national judgement on the value of a treatment relative to alternative uses of resources
179
What is the role of NICE?
provides guidance on whether treatments can be recommended for use in the NHS in England to make sure that effective and cost effective products are made available to patients quickly to minimise variations in the availability of treatments
180
Describe a controversy surrounding NICE
If expensive treatments are not approved by NICE, patients are effectively denied access to them If they are approved, local NHS organisations must fund them, sometimes with adverse consequences for other priorities
181
Why is economic assessment of health needed?
* recognises the reality of fixed NHS resources and brings this to the attention of the public, * exposes the opportunity costs of new interventions, * enables consistency in investment – and disinvestment – decisions * Helps to direct innovation towards health system priorities
182
Define scarcity
Need outstrips resources.
183
Define effectiveness
The extent to which an intervention produces desired outcomes
184
Define efficiency
Getting the most out of limited resources
185
What is technical efficiency?
finding the most efficient way of meeting a need
186
What is allocative efficiency?
choosing between the many needs to be met
187
What is an opportunity cost?
measured in BENEFITS FOREGONE. the cost of committing resources to produce a good or service is the benefits you lose from those same resources not being used in their next best alternative
188
What is economic evaluation?
the comparison of resource implications and benefits of alternative ways of delivering healthcare
189
How are the costs of an intervention measured?
``` Costs of the health care services Costs of the patient’s time Costs associated with care-giving Other costs associated with illness Economic costs borne by the employers, other employees and the rest of society ```
190
How can the benefits of an intervention be measured?
– Impact on health status – Savings in other health care resources (such as drugs, hospitalisations, procedures, etc.) if the patient’s health state is improved – Improved productivity if patient, or family members, returns to work earlier
191
How is cost minimisation analysis carried out?
All outcomes are assumed to be equivalent | the focus of measurement is on costs (i.e. only the inputs).
192
What is a criticism of cost minimisation analysis?
outcomes are rarely equivalent
193
How is cost effectiveness analysis carried out?
used to compare interventions which have a common health outcome. Interventions are compared in terms of cost per unit outcome. If costs are higher for one treatment, but benefits are too, a calculation of how much extra benefit is obtained for the extra cost needs to be done. Key question: Is extra benefit worth extra cost?
194
How is cost benefit analysis carried out?
All inputs and outputs are valued in monetary terms. allows comparison with interventions outside healthcare.
195
What is a criticism of cost benefit analysis?
methodological difficulties e.g. putting monetary value on non-monetary benefits such as lives saved. “Willingness to pay” often used as a tool, but this can be problematic.
196
How is cost utility analysis carried out?
focuses on quality of health outcomes produced or foregone.
197
What is the most frequently used cost utility analysis measure?
quality adjusted life year (QALY) | Composite of survival and quality of life
198
What are the advantages of using QALYs in resource allocation?
measure of both quantity and quality of life
199
What are the disadvantages of using QALYs in resource allocation?
Do not distribute resources according to need, but according to the benefits gained per unit of cost May disadvantage common conditions Technical problems with their calculations QALYs may not embrace all dimensions of benefit; values expressed by experimental subjects may not be representative QALYs do not assess impact on carers or family RCT evidence is also not perfect o Comparison therapies may differ o Length of follow-up o Atypical care o Atypical patients o Limited generalisability o Sample sizes
200
Why has there been an increased interest in patients’ views of health services?
Evidence that patient satisfaction is an important outcome in its own right and is linked to other outcomes Rejection of paternalism, growth of consumerism Increased external regulation of health services emphasis on accountability Means of securing legitimacy
201
What did the NHS Plan emphasise?
organising care around the patient | accountability to patients
202
What did the NHS Act emphasise?
organisations to “involve and consult” patients and the public in: – Planning services they are responsible for – Developing and considering changes in the way those services are provided – Decisions that affect how those services operate
203
How can patient's views of healthcare be assessed qualitatively?
Interviews, focus groups observation
204
What are the advantages of assessing patient's views of healthcare quantitatively?
* Relatively cheap and easy to conduct * Less staff training required * Anonymity more easily guaranteed * Standardised responses makes analysis easier
205
What aspects of communication with healthcare professionals causes patient dissatisfaction?
o Patients not able to share their concerns fully on their own terms o Full histories of the presenting problem not always taken o Staff do not convey reassurance o Staff do not provide appropriate advice
206
What aspects of the content of healthcare causes patient dissatisfaction?
``` o Inconvenience, continuity, access, poor hygiene standards o “Hotel” aspects of care o Waiting times o Culturally inappropriate care o Competence o Health outcomes ```
207
What are some of the challenges of using patients’ evaluations to assess quality?
Sometimes patients’ views may not be reasonable or rational – what then? How to locate responsibility and/or know what to do? Is it a system or individual’s failure? How much resource should be diverted to satisfying issues that give rise to complaints? Will these always be the right places to spend money? How should patients’ concerns about someone’s clinical competence and/or fitness to practice be viewed?
208
Explain functionalism in regards to the patient-professional relationship
falling ill is a socio-cultural experience. lay people don’t have the technical competence to remedy their situation. The sick person is placed in a state of helplessness. Medicine acts to restore people to good health and by so doing restores social equilibrium.
209
Outline the characteristics of the sick role in functionalism
– Being ill presents itself as a legitimate reason to be freed of social responsibilities and obligations – The sick person is placed in a situation of dependence – The sick person should want to get well and not abuse their legitimised exemption from normal responsibilities – The sick person is expected to seek out the requisite technical help in the role of the physician and cooperate with them in the healing process
210
Outline the doctor's role in functionalism
tending to sickness in society – Doctors should use skills for the benefit of patients; act for the welfare of patients rather than their own self-interests; be objective and non-discriminatory – Doctors granted intimate access to patients; autonomy; status; financial reward in order to allow them to use their skills
211
Describe the criticisms of functionalism
The sick role is not well thought out - chronic illness assumes that patients are incompetent and must have passive role. assumes the rationality and beneficence of medicine
212
Outline the conflict theory in regard to the patient-professional relationship
The doctor holds bureaucratic power and has a monopoly on defining health and illness which they can exploit. The patient has little choice but to submit to the institutionalised dominance of the doctor Lay ideas are marginalised and discounted. Medicine is able to colonise areas previously in the control of the ay public, and can pathologise aspects of social life.
213
What is cultural iatrogenesis?
people become dependent on medicine, lose self-reliance and become sick
214
Describe the criticisms of the conflict theory
Patients are not (always) passive – can exert control through non-adherence or the use of complementary therapies. Patients may appear deferential in consultation but assert themselves outside of this. Patients can also seek to ‘medicalise’ issues, too
215
What are the features of a patient centred consultation?
* Explores the patient's main reason for the visit, their concerns and need for information * Seeks an integrated understanding of the patient's world * Finds common ground on what the problem is and mutually agrees management; * Enhances prevention and health promotion; * Enhances the continuing relationship between the patient and doctor.
216
Name an aspirational model of the patient-professional relationship
Patient-centred/partnership models
217
Name explanatory models of the patient-professional relationship
Functionalism | Conflict theory
218
What does the patient contribute to the Patient-Centred consultation?
* their concerns and priorities in relation to presenting problems, * their personal perceptions of costs and benefits of interventions, * complex judgements about the severity of their health problems and unwillingness to undergo risk, discomfort, or other potential costs * the trade-off issues of survival at cost of quality of life
219
What are the challenges of shared decision making with patients?
* People who don’t want to share decision-making * Unknown consequences of involvement * Under what circumstances could/should the power of patients be limited? * Who does final responsibility rest with? * Is there time to achieve this?
220
Why has there been an increased interest in complementary therapies?
* symptoms are not relieved by conventional treatment * real or perceived adverse effects of conventional treatment * preference for a holistic approach to their treatment * more time and attention in their treatment because they are paying for it! * increasing availability and demand * Reported high level of satisfaction
221
What are implications for patients of the use of complementary therapies?
* Social factors – inequalities in ability to afford it * Unqualified and unregulated practitioners – concerns about safety * Risk of missed or delayed diagnosis * Refusal of conventional treatment * Waste money on ineffective treatments * There is no evidence base for the majority of complementary therapies
222
What is a profession?
a type of occupation able to make distinctive claims about its work practices and status
223
What is professionalization?
the social and historical process that results in an occupation becoming a profession.
224
What does professionalization involve?
* Asserting an exclusive claim over a body of knowledge/expertise * Establishing control over market and exclusion of competitors * Establishing control over professional work practice
225
How did medicine undergo professionalization?
1858 Medical Act – gave the General Medical Council power over registration of doctors. controlled entry and removal from medical register approved and inspected medical schools created the doctrine of clinical autonomy – only doctors had enough expertise to monitor and control the work of other doctors
226
What is socialisation?
the process by which professionals learn during their education and training the behaviours and attitudes necessary to assume their professional role
227
Explain the process of self-regulation
The interests of profession are seen as the best guarantee of the interests of the public. any individual admitted to the profession could be assumed to be of good character and competence. It was thought that socialisation and peer-norming would be enough to keep people in check.
228
What are the arguments in defence of self-regulation?
* the unusual degree of skill and knowledge involved in professional work means that non-professionals are not equipped to evaluate or regulate it. * Professionals are responsible – they may be trusted to work conscientiously without supervision. * the profession itself is trusted to undertake the proper regulatory action on those rare occasions when an individual does not perform his work competently or ethically
229
Describe the problems associated with self regulation
* promotes a “self-deceiving vision of the objectivity and reliability of its knowledge and the virtues of its members” * leads to insularity * creates protected monopolies * optimises a profession’s own interests, not their clients
230
How is quality ensured by bureaucracy?
control by management
231
How is quality ensured by markets?
Choice leads the best service ending up at the top.
232
How is quality ensured by professionalism?
Commitment and behaviour and identity leads to quality
233
State some of the problems that occurred within the medical profession because of self regulation
* Staff who were informed of problems found it difficult to act * Patients who told health professionals about problems were often greeted with disbelief or discredited * Whistleblowers were not always believed * NHS disciplinary procedures were found to be ‘cumbersome, costly and inhibiting’ * Doctors were discouraged from raising concerns about each other * Etiquette rule forbid close monitoring of other doctors * There was a shared sense of personal vulnerability * There were high costs associated with speaking out
