Abstract

BACKGROUND: The underlying cause of death (UCOD) documented in the death certificate is a cornerstone in the mortality data that has significant impact on national policies, health system, and socioeconomics. However, a wide range of inaccuracies have been reported worldwide and were linked to multiple factors, including sociodemographic development and lack of physician training. Hence, this study aimed to assess the quality of death certification by reviewing the reported UCOD in the death certificate and study the potential factors that might be associated with inaccuracies.

METHODS: All in-patient deaths that occurred in the Sultan Qaboos University Hospital from January 2020 to 31 December 2020 were included in this retrospective study. The study investigators reviewed all death certifications that were recorded during the study period for the accuracy of the documented UCOD using a systemic framework recommended by the World Health Organization.

RESULTS: The study included 384 mortality cases. The mean age at the time of death was 55.7 ± 27.1 years, and 209 (54.3%) cases were men. Approximately 80% (95% confidence interval: 84-76%) of the deceased patients had inaccurate data on the UCOD. Old age (58.1 ± 25.8 vs 46.5 ± 30.1, p < 0.001), death certification by doctor in training (70.8% vs 51.9%, p = 0.001), and admission under the Department of Medicine (68.5% vs 54.4%, p = 0.019) were more common in mortality cases with inaccurate data on the UCOD. Regression analysis confirmed that old age, male sex, and certification by doctor in training were independent predictors of inaccurate data on the UCOD.

CONCLUSION: Inaccurate data on the UCOD is a prevalent issue in many healthcare settings, especially in the developing countries. Introduction of death certification training in the medical curriculum for medical doctors, implementation of periodic auditing, and provision of feedback are among the evidence-based approaches that are likely to improve the overall accuracy of mortality data.
