Key result
Postoperative adverse events significantly increased total hospitalization expenditures by 2.13-fold and length of stay by 1.72-fold compared to matched surgery patients without adverse events.
Why the study?
The study sought to determine the incidence of postoperative adverse events based on data from the 2006 Taiwan National Health Insurance Research Database.

Hazard Ratio: 2.13 (95% CI 2.09–2.17)
Absolute Event Rate: 276902.77% vs 114607.42%
p-value: p=<0.001
Postoperative adverse events significantly increase both total hospitalization expenditures and length of stay among surgery patients.
Background: The current study sought to determine the incidence of postoperative adverse events (AEs) based on data from the 2006 Taiwan National Health Insurance Research Database (NHIRD). Methods: This retrospective case-control study included patients who experienced postoperative AEs in 387 hospitals throughout Taiwan in 2006. The independent variable was the presence or absence of 10 possible postoperative AEs, as identified by patient safety indicators (PSIs). Results: A total of 17,517 postoperative AEs were identified during the study year. PSI incidence ranged from 0.1/1,000 admissions (obstetric trauma-cesarean section) to 132.6/1,000 admissions (obstetric trauma with instrument). Length of stay (LOS) associated with postoperative AEs ranged from 0.10 days (obstetric trauma with instrument) to 14.06 days (postoperative respiratory failure). Total hospitalization expenditures (THEs) ranged from 363.7 New Taiwan Dollars (obstetric trauma without instrument) to 263,732 NTD (postoperative respiratory failure). Compared to patients without AEs, we determined that the THEs were 2.13 times in cases of postoperative AE and LOS was 1.72 times higher. Conclusions: AEs that occur during hospitalization have a major impact on THEs and LOS.

Yang et al. (2021) conducted a case-control in Surgery patients (n=52,551). Postoperative adverse events vs. No postoperative adverse events was evaluated on Total hospitalization expenditures (THEs) (HR 2.13, 95% CI 2.09-2.17, p=<0.001). Postoperative adverse events significantly increased total hospitalization expenditures by 2.13-fold and length of stay by 1.72-fold compared to matched surgery patients without adverse events.
