Abstract

Background: The registry systems are a tool to provide information which can be used for improvement of medical care and preventive policies over time. The efficacy of trauma registries in improving the quality of care depends on the quality of their data.
Objectives: This study aimed to determine the completeness, reliability, validity, and patient coverage of the Sina Hospital Trauma Registry (SHTR).
Methods: The data collected in the SHTR by May 28, 2021, were used to assess the data completeness. A random sample of 250 patients was re-registered to evaluate the reliability and validity. The intraclass correlation coefficient (ICC) and the kappa and weighted kappa statistics were used to assess the reliability of data and agreement. The coverage was determined by comparing the list of trauma patients obtained from the trauma registry and the one from the hospital information system.
Results: The overall average completeness for all variables was 97.9%. The inter-rater agreement on important variables including Abbreviated Injury Scale (AIS), Injury Severity Score (ISS), and final outcomes was, respectively, perfect (kappa= 0.90) optimal (ICC = 0.72), and substantial (kappa= 0.71). The patient coverage was 79.6%.
Conclusion: The results confirm that the data quality and patient coverage were high. In addition, although the reliability of most variables was acceptable, the agreement between NTRI’s data and the medical record for AIS codes and ISS was moderate.
