Abstract

AIMS: One half of Norwegians die in nursing homes, where death certificates (DCs) are completed by two types of physicians: in-house physicians or physicians on call. The aims of this study were to examine differences in the quality of DCs due to type of physician and to uncover possible implications of errors for the public statistics.

METHODS: DCs from the year 2013 from nursing homes in the catchment area of Akershus University Hospital were examined with regard to logical deficiencies, garbage code diagnoses and type of certifying physician. In one third of cases, the registered causes of death were compared to information in the medical records.

RESULTS: A total of 873 DCs from 24 nursing homes were evaluated. Physicians on call certified 46% of all deaths. Logical deficiencies were found in 34% of all DCs and were more common in DCs from physicians on call. Garbage code diagnoses were used in every third DC, with 'sudden death' or 'cause of death unknown' preferred by physicians on call and 'unspecified pneumonia' preferred by in-house physicians. Comparisons against medical records uncovered missing information in 49% and 35% of DCs from physicians on call and in-house physicians, respectively. A dementia diagnosis was frequently overlooked by both physician types. Garbage code diagnoses were more common in DCs with missing information from medical records.

CONCLUSIONS: Error rates in DCs in nursing homes in Norway are high. The results raise concerns about the validity of public cause of death statistics.
