Abstract:

The objective was to conduct a comparative evaluation of two injury surveillance systems in operation in the Accident and Emergency departments of public hospitals in Jamaica. The evaluation was conducted at 12 hospitals across Jamaica offering varying levels of service delivery. It was designed in three phases: (1) a retrospective review of surveillance system data; (2) prospective process evaluation; (3) system environment evaluation. These data were analysed to determine the sensitivity and specificity of the manual Accident & Emergency Statistical Report (A&ESR) versus the computer-based Patient administration system/Jamaica injury surveillance system (PAS/JISS), and to determine an injury registration rate. Results showed a variation from 8% to 27% in injury registration rates at the hospitals reviewed. The sensitivity of the computer-based PAS ranged from 29.7% to 97.1% while the sensitivity of the manual system ranged from 22.1% to 100%. The computer-based system generally detected a greater percentage of injuries. Problems were identified with missing data fields in the computer-based system, while problems of recording and transcription were identified in the manually-based system. Recommendations were made to improve data quality in both data collection systems. Although shortcomings were identified with the A&ESR, the system is performing the function for which it was designed, that of tracking A&E workload. The PAS/JISS is more user-friendly and a truer reflection of the injury situation.
