Insights
Three emergency physicians (EPs) showed varying concordance in determining the underlying cause of death (UCOD) on death certificates. While EPs had different error patterns, they collectively improved accuracy compared to prior studies.
Area of Science:
- Medical Documentation
- Forensic Medicine
- Public Health
Background:
- Accurate death certification is crucial for public health statistics and epidemiological research.
- Variability in determining the underlying cause of death (UCOD) can impact data reliability.
Purpose of the Study:
- To evaluate the concordance among three emergency physicians (EPs) in identifying the UCOD on death certificates.
- To investigate the types and frequency of errors made by EPs in death certificate completion.
Main Methods:
- Retrospective review of medical records for 106 deceased patients.
- Independent completion of death certificates by three EPs using established selection rules.
- Determination of a gold standard UCOD (GS-UCOD) by unanimous consensus among the three EPs.
- Comparison of EP-assigned UCOD (EP-UCOD) with GS-UCOD and inter-EP concordance analysis.
Main Results:
- Concordance rates between EP-UCOD and GS-UCOD varied by physician: 86% (EP-A), 81% (EP-B), and 67% (EP-C).
- Highest inter-EP agreement was between EP-A and EP-B (0.783), lowest between EP-A and EP-C (0.651).
- No physician listed the mode of dying as the UCOD, indicating adherence to guidelines.
Conclusions:
- Significant variability exists among EPs in determining the UCOD for death certificates.
- Despite inter-physician differences, the EPs demonstrated fewer errors compared to previous studies, suggesting improved practices.
Objective:
This study was conducted to evaluate the concordance between the underlying causes of death (UCOD) on the death certificates written by three emergency physicians (EPs). We investigated errors on the death certificates committed by each EP.
Methods:
This study included 106 patients issued a death certificate in the emergency department of an academic hospital. Three EPs reviewed the medical records retrospectively and completed 106 death certificates independently. The selection of the UCOD on the death certificates by each EP (EP-UCOD) was based on the general principle or selection rules. The gold standard UCOD (GS-UCOD) was determined for each patient by unanimous consent between three EPs. We also compared between the EP-UCOD and the GS-UCOD. In addition, we compared between UCODs of three EPs. The errors on the death certificates were investigated by each EP.
Results:
The rates of concordance between EP-UCOD and the GS-UCOD were 86%, 81%, and 67% for EP-A, EP-B, and EP-C, respectively. The concordance rates between EP-A and EP-B were the highest overall percent agreement (0.783), and those between EP-A and EP-C were the lowest overall percent agreement (0.651). Although each EP had differences in the errors they committed, none of them listed the mode of dying as UCOD.
Conclusion:
This study confirmed that each EP wrote death certificates indicating different causes of death for the same decedents; however, the three EPs made fewer errors on the patients' death certificates compared with those reported in previous studies.
