Overview
Cross-sectional registry analysis reveals high error rates in death certification cause-of-death sections, indicating substantial risks to mortality statistics accuracy.
Key Points
To evaluate the accuracy of records entered into the death notification system, determine primary causes of improperly completed documentation, and identify operational areas requiring correction.
Analyzed a simple random sample of 2,351 death certificates recorded in the Death Notification System database during 2023.
Assessed returned documents across specific sections at a regional Public Health Directorate in 2024 to evaluate error categories, return frequencies, and correction completion times.
Of the 2,351 evaluated certificates, 70.7% were correctly completed, while 29.3% were classified as incorrect or incomplete.
The cause-of-death section represented the primary source of documentation failure, accounting for 80% of all identified errors or omissions.
Deficient records triggered multiple administrative revisions, including single instances requiring up to 11 returns to the same certifying physician.
