Accuracy of death certification in cutaneous squamous cell carcinoma: A retrospective case review

Provider reported challenges with completing death certificates: A focus group study demonstrating potential sources of error

Objectives

To characterize the experiences of providers in completing the cause of death section on death certificates, with particular reference to deaths in people who have cancer.

Methods

Focus groups were conducted until thematic saturation was reached, resulting in four groups over three months. Participants were from a variety of specialties and levels and types of training. Focus groups were recorded and transcribed verbatim and analyzed using constant comparison analysis.

Results

Three types of challenges to case classification were identified. 1) Infrastructural and procedural challenges encountered when completing death certificates, including the rigid structure of the form, lack of training in its completion, and lack of real-time feedback. 2) Clinical uncertainty and the varied approaches providers take to determine the cause of death based on their perception of the purpose of the death certificate. 3) Choosing cause of death in decedents with a history of cancer.

Conclusions

There are specific and substantial challenges in the death certification process that lead to errors in documenting the cause of death, but many of these challenges could be addressed with structural change to the forms or mechanism of training. Using these data to inform change could improve the death certification process and reliability of this data.

Keratinocyte Carcinoma Mortality in the United States as Reported in Death Certificates, 2011-2017

BACKROUND

Keratinocyte carcinoma (KC) mortality is relatively modest and its measures are subject to considerable error. Deaths due to KC have been decreasing through 2000 and were relatively stable until 2010.

OBJECTIVE

To estimate the KC mortality rates (MRs) from 2011 to 2017 in USA based on death certificates.

METHODS

A population-based analysis of Center of Disease Control and Prevention data. Main outcomes and measures were the age-adjusted (US 2000 standard population) MRs.

RESULTS

Overall, KC MRs increased significantly (b = 0.04, p < .01). For the period studied, KC MR was 1.24 per 100,000 persons per year (0.62 for sun-exposed sites, 0.38 for genital and 0.23 for perianal sites). At sun-exposed genital and perianal anatomic sites, KC MRs have been increasing in whites, but not in blacks.

CONCLUSION

There was a 17% decrease in the KC MRs until 2000, followed by an increase of 44% through 2017. The accuracy of KC MRs is uncertain. If indeed the increase in mortality is verified, causes may include an increase in KC incidence, an increase of immunosuppressed populations, and changes in the cause of death documentation.
