Area of Science:

  • Public Health
  • Demography
  • Health Systems Research

Background:

  • Established in 2005 by the Dodowa Health Research Centre (DHRC) in Ghana.
  • Aimed to create a population database for a community health insurance pilot.
  • Operates in a rural, scattered settlement area in south-eastern Ghana.

Purpose of the Study:

  • To establish and maintain a comprehensive health and demographic surveillance system.
  • To provide accurate population data for research and health program evaluation.
  • To facilitate data sharing for collaborative health initiatives.

Main Methods:

  • Biannual collection of data on vital events (pregnancies, births, deaths, migration, marriages) via household registration.
  • Annual collection of data on education, immunization, and socioeconomic status.
  • Conducts verbal autopsies for all deaths and utilizes community key informants (CKI) for event notification.

Main Results:

  • By 2010, registered 111,976 residents in 22,767 households.
  • Established robust data collection mechanisms in a rural setting.
  • Fostered collaborations with local health directorates and government authorities.

Conclusions:

  • The DHDSS provides a valuable platform for health and demographic research in Ghana.
  • The system's data supports evidence-based health policy and interventions.
  • Adherence to INDEPTH data-sharing policies promotes wider research collaboration.
