BACKGROUND: Postoperative adverse outcomes in @entity1 with pressure @entity1066 are not completely understood. This study evaluated the association between preoperative pressure @entity1066 and adverse events after major surgeries. METHODS: Using reimbursement claims from Taiwan's National Health Insurance Research Database, we conducted a nationwide retrospective cohort study of 17391 @entity1 with preoperative pressure @entity1066 receiving major surgery in 2008-2010. With a propensity score matching procedure, 17391 surgical @entity1 without pressure @entity1066 were selected for comparison. Eight major surgical @entity260 and 30-day postoperative mortality were evaluated among @entity1 with pressure @entity1066 of varying severity. RESULTS: @entity1 with preoperative pressure @entity1066 had significantly higher risk than controls for postoperative adverse outcomes, including @entity295 , @entity55 , @entity64 , @entity293 , and @entity810 . Surgical @entity1 with pressure @entity1066 had approximately 1.83-fold risk (95% confidence interval 1.54-2.18) of 30-day postoperative mortality compared with control group. The most significant postoperative mortality was found in those with serious pressure @entity1066 , such as pressure @entity1066 with @entity281 , @entity2688 , wound or treatment by change dressing, hospitalized care, debridement or antibiotics. Prolonged hospital or intensive care unit stay and increased medical expenditures were also associated with preoperative pressure @entity1066 . CONCLUSION: This nationwide propensity score-matched retrospective cohort study showed @entity260 and mortality in @entity1 with preoperative pressure @entity1066 . Our findings suggest the urgency of preventing and managing preoperative pressure @entity1066 by a multidisciplinary medical team for this specific population.
