Summary

This study evaluates the Cambodia Road Crash and Victim Information System (RCVIS), a nationwide surveillance system designed to monitor road crash injuries and fatalities. The research was motivated by the disproportionate burden of road traffic injuries in low- and middle-income countries and Cambodia’s rapid increase in motorized vehicles, which doubled from 714,000 in 2006 to 1.6 million in 2010. Reliable surveillance data are critical for assessing injury burdens and evaluating safety interventions, prompting the U.S. Centers for Disease Control and Prevention to assess whether RCVIS captures data efficiently and effectively. The evaluation utilized the CDC’s “Guidelines for Evaluating Public Health Surveillance Systems” as a framework, assessing attributes including usefulness, flexibility, acceptability, sensitivity, representativeness, data quality, and timeliness. Methods included in-person interviews with stakeholders from the Ministries of Health and Interior, the National Road Safety Committee, and Handicap International, alongside a review of RCVIS annual reports and operational documents. Sensitivity was further assessed by comparing RCVIS counts to estimates from the 2010 Demographic and Health Survey, while data quality was measured by analyzing missing values in 2010 police and health facility records. Results indicated that RCVIS is widely used for strategic planning, with annual reports disseminated to over 250 stakeholders within 10 months. In 2010, the system reported 1,816 fatalities and 16,471 nonfatal injuries, with motorcyclists comprising the majority of casualties. However, significant limitations were identified regarding acceptability and representativeness. While 100% of police districts participated, only 65% of hospitals reported data in 2010, and hospital participation declined sharply between 2007 and 2008. This inconsistency led to a 35% decrease in reported nonfatal injuries from 2007 to 2010, a trend likely attributable to reduced reporting rather than actual injury reduction, given the concurrent rise in vehicle registrations. Data quality issues included high rates of missing information on safety behaviors, such as helmet use (58% missing in police data). Comparison with the Demographic and Health Survey suggested RCVIS largely undercounts the total road crash burden. The authors conclude that while RCVIS provides a strong foundation for surveillance, inconsistent hospital reporting compromises data representativeness and trend analysis. Recommendations include standardizing reporting procedures, increasing senior-level buy-in at health facilities, and demonstrating the utility of data to healthcare providers to improve acceptability. The study highlights the fragility of surveillance systems reliant on voluntary participation and the importance of aligning data collection burdens with perceived benefits for sustaining long-term system integrity.
