Injury surveillance in countries of the African Region

In 2004, WHO conducted a study to assess violence and injury prevention efforts in African countries. Results highlighted gaps and recommendations to improve data collection and capacity building for injury prevention. Key findings from surveys, including collection methods, institutions involved, and suggestions for standardization, were presented. The study emphasized the need for a core data set and reevaluation of surveillance methods to ensure effectiveness and inclusivity.

  1. Injury surveillance in countries of the African Region World Health Organization

  2. Background • In 2004 WHO embarked on an exercise to compile national and regional profiles of violence and injury prevention activities • To identify gaps where little or no efforts exist • To enable WHO and other global partners to advocate for increased resources for VIP • To enhance WHO’s ability to assist Member States to build capacity for violence and injury prevention activities

  3. Method • Questionnaires in English, French and Portuguese were sent to 46 countries • 35 completed surveys returned (76%) • 1 survey sent back due to missing information, did not return • 8 countries (17.4%) promised to return surveys but did not • 4 countries did not respond at all despite repeated reminders

  4. The study covered many aspects of VIP capacity, but only results concerning data will be presented.

  5. Collection of health-related statistics (n=32) * Other: e.g. Local classification system

  6. Type of unintentional injury data collected by the system

  7. Type of intentional injury data collected by the system

  8. How injury statistics are made accessible *Other: e.g. Police records, annual health statistics

  9. Don't know 3% Yes 97% Other institutions/organisations collect injury-related data (n=32) • Data collected by, e.g.: • Federal Road Safety Commission • Ministry of Domestic Affairs • Legal Assistance Centre • University Hospitals

  10. Number of Ministry of Health staff working on injury and violence prevention activities

  11. Within the Ministry of Health budget, funds are allocated specifically for Injury and/or violence prevention (n=30)

  12. Ministries conducting injury and violence prevention activities *Other: e.g. Federal Road Safety Commission, Ministry of Gender and Community Development, Police Department

  13. Focus on Mozambique • Hosp based surveillance since 2000 • 3 sites all in capital Maputo • Fatal injury surveillance since Mar 2005 • one site (morgue) • Evaluation June 2006 • Simple, flexible, acceptable, timely • Surve data has managed to raise awareness • Data not used for intervention planning or evaluation

  14. Other characteristics • Representativeness: difficult to guage – hospitals see majority of injury patients that visit the ER in Maputo, BUT … self selection? Issues of access • Sensitivity: about 90% • Predictive value positive: “very high”

  15. Some recommendations of the evaluation • Standardize collection formats in hospitals • Change case definition to exclude repeat visits for same injury • Collect WHO recommended core minimum data set (currently about 50% of core) • Include injury severity

  16. Conclusion • A lot of diversity, so recommendations need to be mindful of this. • Need to reinforce the idea of a minimum core data set • Reexamine the role of sentinel sites
