Trends in Dermatopolymyositis Mortality, 1999-2022: A Nationwide Population-Based Study, United States.

ABSTRACT:

Objective

We evaluated trends in dermatopolymyositis (DPM) mortality relative to all-cause mortality in the United States from 1999 to 2022.

Methods

We used the Centers for Disease Control and Prevention's databases (Multiple Causes of Death for 1999-2020 and Provisional Mortality Statistics for 2021 and 2022) to obtain death counts for DPM and non-DPM (all causes other than DPM). We calculated age-standardized mortality rates (ASMRs) for both groups and computed the ratio of DPM-ASMR to non-DPM-ASMR for each of the 24 years. We performed joinpoint regression analysis to estimate annual percent change (APC) in DPM-ASMRs and non-DPM-ASMRs and in the DPM-ASMR to non-DPM-ASMR ratios overall and by sex, age, and race and ethnicity.

Results

There were 12,882 DPM and 63,549
