Indicators of Health
Health indicators are quantifiable measures used to assess the health status of a population, track changes over time, and compare health outcomes across different regions or groups.
Primary Categories of Health Indicators
| Category | Key Examples |
|---|---|
| Mortality | Crude Death Rate, Infant Mortality Rate, Maternal Mortality Ratio, Case Fatality Rate. |
| Morbidity | Incidence, Prevalence, Notification Rates, and Attendance rates (OPD/IPD). |
| Disability | HALE (Health Adjusted Life Expectancy), DALYs (Disability-Adjusted Life Years). |
| Nutritional | Anthropometric measurements (BMI, weight-for-age, stunting/wasting). |
| Healthcare Delivery | Doctor-to-population ratio, hospital bed availability, and immunization coverage. |
High-Yield Clinical Notes:
- Incidence vs. Prevalence: Incidence measures *new* cases (risk), while Prevalence measures *total* existing cases (burden).
- DALYs: Calculated as YLL (Years of Life Lost) + YLD (Years Lived with Disability). This is the gold standard for measuring the global burden of disease.
- Indicator Criteria: A good health indicator must be valid (measures what it claims), reliable (consistent), sensitive (detects changes), and feasible (easy to obtain).
