A
- Is the insured peril related to mortality, morbidity or retrenchment?
- What is the time frame under consideration eg during acute in-hospital admission, next month or year?
- What population is being considered? eg in-hospital, paediatric patients, etc
- What is the purpose eg pricing, contracting with healthcare provider

- Certain clinical conditions are sex specific.
- male - prostate cancer
- femaile breast cancer
7

Risk factor: race
A
- well-documented differences exist in disease prevalence by race.
- once adjusted for socio-economic factors, disparities in healthcare between different enthic groups are greatly reduced,but still not elimininated.
8
Q
Risk factor: acute clinical stability
A
- measure a person’s physiological functioning using homeostatic measures:
- heart rate, body temperature
- blood pressure
- this is needed to check if patient is facing imminent risk of death.
9
Q
Risk factor: principal diagnosis
A
-It is often necessary to understand the extent & severity of a principal diagnosis eg type of bacterial or viral infection for a patient diagnosed with gastritis.
10
Q
Risk factor: Co-morbidities
A
- refers to a clinical condition which exists simultaneously with another condition, usually independently of another medical condition.
- eg diabetes and a heart condition.
11
Q
Risk factor: Functional status
A
- often referes to observable basic activities of daily living(ADL) and instrumental ADLs.
- ADL egs: feeding,washing, toileting
- instrumental ADLs : shopping, cooking
12
Q
Risk factors:Socio-economic status
A
- Studies have shown that it is important to adjust for socio-economic factors when comparing healthcare outcomes.
- poor living standard and nutrition contribute to morbidity risk.
- doctors may keep patients with lower socio-economic status in hospitals longer they believe home conditions are not conducive for recuperation.
13
Q
Risk factors: Lifestyle factors
A
- many lifestyle factors influence morbidity: eg alcohol use, smoking, use of illicit drugs.
- these can be closely linked with chronic conditions.
14

15
Q

A
- budgeting (appropriate fund allocation by State)
- measuring efficiency…
…4 app to:
>network selection
>price negotiations
>managing facilities
>insurance plans - risk management
