Medical certificate of cause of death: Looking for an European single standard

Looking at the future of the medical certification of cause of death (MCCD) in England and Wales

Internationally, the quality of death certification is poor although there are multiple efforts underway to improve the process. In England, a new medical certification system has been proposed to improve the quality of data. We surveyed general practitioners (n = 95) across the West Yorkshire area of England to appraise their views regarding whether further possible changes to the death certification system could promote their quality.

Cause of death coding in asthma

BACKGROUND

While clinical coding is intended to be an objective and standardized practice, it is important to recognize that it is not entirely the case. The clinical and bureaucratic practices from event of death to a case being entered into a research dataset are important context for analysing and interpreting this data. Variation in practices can influence the accuracy of the final coded record in two different stages: the reporting of the death certificate, and the International Classification of Diseases (Version 10; ICD-10) coding of that certificate.

METHODS

This study investigated 91,022 deaths recorded in the Scottish Asthma Learning Healthcare System dataset between 2000 and 2017. Asthma-related deaths were identified by the presence of any of ICD-10 codes J45 or J46, in any position. These codes were categorized either as relating to asthma attacks specifically (status asthmatic; J46) or generally to asthma diagnosis (J45).

RESULTS

We found that one in every 200 deaths in this were coded as being asthma related. Less than 1% of asthma-related mortality records used both J45 and J46 ICD-10 codes as causes. Infection (predominantly pneumonia) was more commonly reported as a contributing cause of death when J45 was the primary coded cause, compared to J46, which specifically denotes asthma attacks.

CONCLUSION

Further inspection of patient history can be essential to validate deaths recorded as caused by asthma, and to identify potentially mis-recorded non-asthma deaths, particularly in those with complex comorbidities.

Will medical cause of death certifications data quality improve in the UK with the new medical examiner system?

OBJECTIVES

There are deficits in the completeness, accuracy and timeliness of death certification internationally. In April 2023, England implemented a statutory Medical Examiners system primarily aiming to improve the quality of certification of death data. We sought to assess the current quality of death certification among general practitioners and medical examiners.

METHODS

An online survey was conducted with general practitioners and medical examiners in the Yorkshire region to determine how Medical Certifications of Cause of Death (MCCD) are completed and commonly experienced sources of errors (e.g., a lack of a reported time frame, absent or inadequate reporting of comorbidities, incorrect underlying cause-of-death, and an inaccurate sequence of events).

RESULTS

The survey was completed by general practitioners (n = 95) and medical examiners (n = 9). Participant responses, including to a hypothetical case, confirmed the quality of the certification was less variable among MEs compared to GPs, but still below international standards.

CONCLUSIONS

Efforts to enhance the quality of death certification require further consideration. Mandating a medical examiner system may not lead to intended improvements in the quality and cause of death data that form a critical component of mortality statistics that underpin health planning and monitoring.

Consistent acting, legal knowledge and competence of external postmortem examination in Dutch hospital settings

A crucial role in the external postmortem examination system of the Netherlands is that of the attending physicians, who are either general practitioners or physicians in hospitals. They perform 85% of all external postmortem examinations and must immediately report to forensic physicians all unnatural deaths and deaths that they are not convinced to be natural. These attending physicians need therefore to be properly qualified and need to be competent, by acting consistently and by having knowledge of the appropriate laws surrounding external postmortem examination. The aim of this study is to analyse the competence of the attending physicians in hospital settings. This research studied whether they regard themselves as competent, whether they had knowledge of and acted according to the appropriate laws, and whether they acted consistently in following the procedures around external postmortem examinations. A survey was conducted among clinicians. After discarding 23 questionnaires for various reasons, 326 datasets remained on which the research was based. There was no significant difference between the medical specialists (79%) and the residents and fellows (86%) in their feeling of being competent in undertaking external postmortem examinations. The answers of the respondents showed at least one inconsistency in 54%. Of the respondents 34% were considered as to have knowledge of relevant laws. Of the respondents 21% felt competent, was consistent in all their answers and scored a 100% on legal knowledge. The study showed that though a physician might feel competent, this does not mean he actually is competent in performing an external postmortem examination. Furthermore, the extent of a respondents' ignorance of the appropriate laws and the inconsistency in acts and thoughts is undermining the system of postmortem examination.

Death, demography and the denominator: Age-adjusted Influenza-18 mortality in Ireland

Using the Irish experience of the 1918-1919 Spanish flu pandemic ("Influenza-18"), we demonstrate how pandemic mortality statistics can be sensitive to the demographic composition of a country. We build a new spatially disaggregated population database for Ireland's 32 counties for 1911-1920 with vital statistics on births, ageing, migration and deaths. Our principal contribution is to show why, and how, age-at-death data should be used to construct the age-standardised statistics necessary to make meaningful comparisons of mortality rates across time and space. We conclude that studies of the economic consequences of pandemics must better control for demographic factors if they are to yield useful policy-relevant insights. For example, while Northern Ireland had a higher crude death rate during the first wave of the Covid-19 pandemic, it also has an older population; age-adjusted mortality paints a very different picture.
