Which data type best demonstrates trends in disease incidence in the community?

• A. Patient satisfaction surveys
• B. Census data
• C. Health indicators such as incidence and mortality rates
• D. Risk management data

Answer: (C)

Tracking disease trends in a community relies on data that quantify how many people develop a disease and how many die from it over time. Health indicators such as incidence and mortality rates are designed for this purpose. Incidence rate captures new cases in a defined population during a specified period, usually per 100,000 people, while mortality rate tracks deaths due to the disease in the same way. Because these metrics are time-bound and population-based, they show whether the disease is increasing, decreasing, or remaining stable, and they allow comparisons across different groups or areas. They also help assess the impact of interventions, such as vaccination programs or improved treatment access. Patient satisfaction surveys reflect experiences with care rather than how often disease occurs. Census data provides population size and demographics, which are helpful for calculating rates but does not by itself track disease trends over time. Risk management data focuses on safety and adverse events within healthcare settings, not community disease burden.
