Global, Regional, and National Levels and Trends in the Burden of Pressure Ulcer from 1990 to 2019: A Systematic Analysis for the Global Burden of Disease 2019.

Pressure ulcer (PU) is a type of chronic ulcer, placing a high burden not only on patients' families but also on national healthcare systems globally. To determine the level, trends, and burden of PU worldwide and to provide an essential foundation for building targeted public policies on PUs at the national, regional, and global levels, data on PU were obtained from the Global Burden of Disease (GBD) 2019 Study. The incidence, disability-adjusted life years (DALYs), and deaths of PUs in 204 countries and regions from 1990 to 2019 were calculated and stratified by sex, age, geographical location, and sociodemographic index (SDI). The estimated annual percentage change (EAPC) of incidence, DALYs, and deaths was calculated to evaluate the temporal trends. A total of 3,170,796 new cases (95% uncertainty interval (UI), 3,499,729-2,875,433 cases) of PU were identified globally in 2019, more than 55% of which were among male individuals, and most of the new cases were concentrated in those 75-90 years of age. The burden of PU measured in DALYs was 481 423 (95% UI, 583 429-374 334) in 2019, 73% and 27% of which could be attributed to years of life lost (YLLs) and years lived with disability (YLDs), respectively. The burden increased gradually from 1990 to 2019 (from 267 846 [360 562-211 024] to 481 423 [95% UI, 583 429-374 334]). A total of 24 389 deaths were attributed to PU (95% UI, 31 260.82-17 299). The EAPC of incidence, DALYs, and deaths were negative in most regions, the age-standardized rate (ASR) of incidence, DALYs, and deaths were considered to be decreasing in most of the regions, and the EAPCs were negatively correlated with the SDI levels, universal health coverage (UHC), and gross domestic product (GDP), which shows that the ASRs of PU decreased as the economy developed and countries' healthcare system performances improved.
