What is evidence-based decision making (EBDM)?
Process for identifying and using most up-to-date (and relevant) evidence to inform
decisions for individual patient problems.
What does EBDM involve?
Patient preferences
Available resources
Research evidence
Clinical expertise
Why is decision making in medicine important?
Doctors make decisions constantly
The decisions have effects on patients, families, and society
An understanding of decision making, and the role of evidence, can help improve medical practice
Why do we need EBDM?
Limited time to read
Inadequacy of ‘traditional’ sources of information - text books often out of date
Disparity between diagnostic skills/clinical judgement (which increase over time) and
up-to-date knowledge/clinical performance (which decrease).
What are the 6 types of research papers?
Cohort study
Case control
Qualitative
Randomised control trials
Diagnostic and screening
Systematic reviews
What is the 5 process of EBDM?
- Identifying the need for information
- Identifying the best evidence
- Critically appraising the evidence
- Integrating the critical appraisal to clinical expertise
- Evaluating and seeking ways to improve.
What are the two types of questions in EBM?
Foreground question
Background question
What is a background question?
Generalised and usually formed off our own experience. Has two parts to it a ROOT and Disorder
What is a foreground question?
More specific and detailed question about managing patients with a disorder.
Uses PICO
What does PICO stand for?
P- Patient
I- Intervention
C- Comparative intervention
O- Outcome clinically
What are the 4 steps in the approach to smoking cessation?
- Health education and general information to enhance motivation for quitting (light
smokers) - Brief advice from a health professional to quit smoking (light smokers)
- Advice, nicotine replacement, follow-up by a specialist (moderately motivated,
medium dependence smokers) - Specialised counselling rooms and agencies working with group sessions (highdependent smokers)
What is antibiotic resistance?
Bacteria change so antibiotics no longer work in people who need them to treat
infections
What are the reasons for the widespread use of antibiotics?
Increase in global availability
Uncontrolled sale in many low or middle income countries
What are some of the causes of antibiotic resistance?
Use in livestock for growth promotion
Releasing antibiotics into the environment during pharmaceutical manufacturing
Volume of antibiotic prescribes
Missing doses when taking antibiotics
Inappropriate prescribing of antibiotics
How can antibiotic resistance be prevented?
Using antibiotics only when prescribed by a doctor
Completing the full prescription
Never sharing antibiotics or using leftover prescriptions
Only prescribing antibiotics when they are needed
Using the right antibiotics to treat the illness
Which factors influence infection?
Infectious agents - Ability to reproduce, survival, ability to spread, infectivity,
pathogenicity
Environment - Contamination, other humans, animals, water
Mode of transmission - Droplet, airborne, aerosol, direct consumption, fecal-oral
route, blood bourne, sexual contact, zoonosis
Portal of entry - Mouth, nose, ears, genital tract, skin
Host factors - Chronic illness, nutrition, age, immunity, lifestyle (e.g. smoking, drugs
etc)
what healthcare associated infections are on mandatory surveillance?
c diff, MRSA bacteraemia, MSSA bacteraemia
what are the most common Healthcare associated infection?
C. diff, UTI, Pneumonia most common
What are the most important infectious diseases in developing countries?
Pneumonia, chronic diarrhoea, malaria, HIV/AIDS
What is surveillance?
Systematic collection, collation and analysis of and Publication of data so that appropriate control measures can be taken
What is the purpose of surveillance?
Serve as an early warning system for impending public health emergencies
Document the impact of an intervention, or track progress towards specific goals
Monitor and clarify the epidemiology of health problems, to allow priorities to be set .
What can be done to reduce the risk of nosocomical infections?
Prevention - Hand washing, sterilisation and decontamination of instruments
Detection, investigation and control of outbreaks
Policies and procedures to prevent and control infection
- Education and training
What is global health?
Global health refers to the health of the world’s population and it aims to improve health and achieve health equality worldwide.
What is international health?
Health defined by geography (poor nations), problems (infections, water, sanitation),
instruments (infection control, aid) and a recipient and donor relationship
