PURPOSE: Air pollution is an emerging risk factor for adverse surgical outcomes, but its impact on postoperative kidney health is unclear. This study aimed to examine the association between exposure to multiple air pollutants and the risk of acute kidney injury (AKI) after surgery.
METHODS: We conducted a retrospective cohort study among inpatients who underwent surgery under anesthesia at three academic medical centers from 2015 to 2023. The Air Quality Health Index (AQHI) was used to comprehensively quantify and score multiple ambient air pollutants. In this study, short-term exposure was defined as the 30-day average prior to surgery, with long-term exposure defined as the 2-year average. The main endpoint was the occurrence of AKI within 7 days after surgery, stage 2 or 3 acute kidney injury (AKI 2+), and acute kidney disease (AKD).
RESULTS: This study included 112, 643 surgical patients (with an average age of 54 years, 48.4% of whom were male), among whom 95.3% underwent non-cardiac surgeries and 80.8% had non-emergency surgeries. In the quartile-based analysis of long-term AQHI exposure, higher AQHI levels were associated with increased odds of renal injury AKI (aOR(adjusted Odds Ratio) 1.24; 95% CI, 1.14-1.34), AKI 2+ (aOR 1.29; 95% CI, 1.19-1.53), and AKD (aOR 1.18; 95% CI, 0.97-1.43). However, in the short-term exposure analysis, associations were attenuated but remained significant. AKI (aOR 1.24; 95% CI, 1.14-1.34), AKI 2+ (aOR 1.28; 95% CI, 1.12-1.45), and AKD (aOR 1.18; 95% CI, 1.12-1.45).
CONCLUSION: This study found that air pollution significantly impacts postoperative adverse renal outcomes.
