Post-operative Mortality Trends for Complicated Appendicitis: Adults with and without Disabilities

Abstract Background Even for the same complicated appendicitis, the prognosis may vary if appropriate post-operative care and follow-up are not provided. We aimed to investigate the 10-year trend of complicated appendicitis mortality among disabilities and non-disabilities peoples in Korea, recognizing potential disparities in post-surgical outcomes and the importance of adequate post-operative care. Methods Patients with complicated appendicitis were classified by severity using DRG codes. Causes of death were categorized into infectious, respiratory, cardiovascular, and digestive diseases using ICD-10 data. Age-adjusted mortality rates were calculated annually from 2008 to 2017 based on disability presence, severity, and type. Factors associated complicated appendicitis mortality were analyzed using multivariate logistic regression models. Results The mortality of complicated appendicitis was 10.2 times (40.8% vs. 413.9%) higher in people with disabilities, especially those with severe disabilities. This difference was more evident in patients with a severe disability (aOR=2.12, 95% CI:1.58-2.86), intellectual or psychological disability (aOR=2.95, 95% CI:1.49-5.85) and internal organ problems (aOR=2.05, 95% CI:1.28-3.28). Conclusions Our findings suggest that insufficient post-operative care among disabled peoples, especially those with severe disabilities, internal organ problems, and intellectual or psychological disabilities, may impact outcomes. This is exacerbated by poor healthcare facilities and limited disability awareness among healthcare workers. Additionally, further research is required to uncover unexplained mortality causes. Funding: This research was supported by the National Research Foundation of Korea (NRF) grant funded by the Ministry of Education (No. 2022R1I1A3070074) and by a grant of Patient-Centered Clinical Research Coordinating Center (PACEN) funded by the Ministry of Health & Welfare, Republic of Korea (grant number: HC23C0165). Key messages • Complicated appendicitis mortality rates show a stark 10.2-fold disparity between people with and without disabilities. • Severe disabilities, intellectual or psychological disabilities, and internal organ problems heighten the risk, emphasizing the importance of disability-inclusive healthcare practices.
