Definition of domestic abuse
Any incident or pattern of incidents of controlling, coercive, threatening behaviour, violence or abuse between those aged 16 or over who are or have been intimate partners or family members regardless of gender or sexuality
Types of abuse
psychological physical sexual financial emotional
Impact of domestic abuse on health
Traumatic injuries
Somatic problems (GI, headaches, chronic pain)
Psychological (PTSD, depression, anxiety)
Indicators of domestic abuse
Not witnessed by anyone
Repeat attendance
Delay in seeking help
Many women are prevented by perpetuator from seeking help
Risk levels of domestic abuse
STANDARD: current evidence does not indicate likelihood of serious harm
MEDIUM: Identifiable indicators of risk but serious harm unlikely unless there is a change in circumstances
HIGH: imminent risk of harm
Interventions for domestic abuse
MARAC - multi agency risk assessment conference
IDVA - independent domestic violence advisor
Domestic homicide review
Primary prevention
Prevent disease before it ever occurs
Secondary prevention
Early detection and prompt effective intervention
Tertiary prevention
Reduce long term impairments or disabilities
Population approach to screening
Population wide basis to shift risk factor distribution curve
High risk approach
Identify individuals above a certain cut off and treat them
Types of screening
Population based Opportunistic Screening for communicable disease Pre employment/occupational Commercially provided
Wilson and Junger screening criteria
Important health problem
Latent/preclinical phase
Natural Hx known
The Test:
has to be suitable (sensitive, inexpensive, specific) and acceptable
The Treatment:
has to be effective and an agreed policy on whom to treat
The organisation:
Facilities, costs and benefits, on-going process
Sensitivity
Proportion of people with the disease who are correctly identified by the screening test
Specificity
Proportion of people without the disease who are correctly excluded by the test
PPV
Proportion of people with a positive result who actually have the disease
NPV
Proportion of people with a negative result who do not have the disease
Lead time bias
Length of time between detection of disease and its usual clinical presentation/diagnosis
E.g Huntingdon’s (detection may not actually prolong life)
Length time bias
A comparison of survival in screen detected patients with non screen detected patients may be biased as there will be a tendency to compare less aggressive with more aggressive cancers
E.g. ‘slow growers’ more likely to be detected on screening
What is epidemiology?
The study of the frequency, distribution and determinants of diseases and health related states in populations in order to prevent and control disease
Incidence
No. of new cases present during a specific time period
Prevalence
No. of existing cases
Incidence rate
No of new cases per population AT RISK during a given time period
Absolute risk
Has units e.g. 50/1000
