Community Medicine
Community medicine asks you to think about populations, not just patients: determinants of health, primary health care organisation, community diagnosis and the structure of the Egyptian health system. The Board tests definitions, levels of prevention and how a family health unit plans for its catchment population.
Core rules
- Health determinants: biological, behavioural, environmental, social and economic, and health-system factors. Health is produced mostly outside the clinic.
- Levels of prevention: primordial (prevent risk-factor emergence), primary (prevent disease before it occurs), secondary (early detection and treatment), tertiary (limit disability and rehabilitate), quaternary (avoid overmedicalisation).
- Primary health care: Alma-Ata 1978 and the Astana declaration 2018. Core attributes are first contact, accessibility, continuity, comprehensiveness and coordination, supported by community participation and intersectoral action.
- Egypt's system: Ministry of Health and Population provides facilities and programmes; the Health Insurance Organization covers defined groups; the Universal Health Insurance Authority, established under Law 2 of 2018, is rolling out phased coverage; the private sector and NGO providers complete the picture. Family health units are the entry point, each serving a defined catchment population, with a family medicine district team supervising quality and referral.
- Community diagnosis: describe the population (size, age-sex structure, literacy, employment, water and sanitation), measure health status (mortality, morbidity, coverage), identify risk factors and resources, then prioritise and plan with the community.
- Notifiable disease surveillance and outbreak investigation follow the same logic: verify the diagnosis, define and count cases, describe by time, place and person, generate a hypothesis, institute control and communicate.
Worked example
A family health unit notes rising diarrhoea cases in children under five in one village. Reasoning: compute attack rates by age and by water source; if cases cluster among households using a particular tap, suspect a common-source water contamination; take water samples, advise boiling and chlorination, treat cases with ORS and zinc, notify the district, and re-check weekly to confirm the epidemic curve is falling.
Traps that cost marks
- Confusing primary care (services) with primary health care (a philosophy including equity and community participation).
- Reporting incidence and prevalence interchangeably when describing a community burden.
