Summary: When the resources in health sector are limited, the incorporation of sound epidemiological information into the decision process can promote efficient allocation of resources for development and provide a sound basis for evaluation of directed strategies for health care and disease prevention control programs. The routine health information systems, based on health provider data, and population-based surveys are the most important sources of such data.Summary: Population-based household health surveys are mainly of two kinds: Health Interview Surveys (HIS) which rely on self reports/interviews, and Health Examination Surveys (HES) which may entail an interview, a physical examination, one or more chemical tests, radiological and ultrasound screens, and other assessments to provide a health profile.Summary: Pakistan Medical Research Council (PMRC) in collaboration with the National Center for Health Statistics (NCHS), CDC, US Public Health Services conducted a National Health Survey of Pakistan 1990–94. Using the NHSP data, on diabetes, hypertension, arthritis, and immunization coverage this study attempted to mainly examine the following issues: (1) differences in prevalence estimates for diabetes, hypertension, arthritis, and immunization coverage for measles as derived from HIS and HES; (2) excent of agreement between HIS and HES on these conditions; (3) the validity of HIS for these specific parameters by taking HES as the criterion; (4) factors/characteristics which influence the agreement and/or the validity.Summary: Prevalence estimates generated by HIS varied significantly from those of HES. Over 70% of diabetics and hypertensives diagnosed on HES had not been previously diagnosed, were unaware of their disease status, or did not report as such on HIS. Significant over reporting was observed for immunization coverage and arthritis (45% and 78%, respectively). The validity of HIS as well as agreement between HIS and HES mostly improved with a rise in socio-economic status, an increase in education, age, level of BMI, and for urban residents.
