Surgical site infections (SSI) are one of the most common and costly hospital-acquired infections in the United States. Meteorological variables such as temperature, humidity, and precipitation may represent a neglected group of risk factors for SSI. Using a national private insurance database, we collected admission and follow-up records for National Healthcare Safety Network-monitored surgical procedures and associated climate conditions from 2007 to 2014. We found that every 10 cm increase of maximum daily precipitation resulted in a 1.09 odds increase in SSI after discharge, while every g/kg unit increase in specific humidity resulted in a 1.03 odds increase in SSI risk after discharge. We identified the Southeast region of the United States at highest risk of climate change-related SSI, with an estimated 3% increase in SSI by 2060 under high emission assumptions. Our results describe the effect of climate on SSI and the potential burden of climate-change related SSI in the United States.
手术部位感染（SSI）是美国最常见和最昂贵的医院获得性感染之一。气象变量，如温度、湿度和降水，可能代表着一组被忽视的 SSI 风险因素。我们使用国家私人保险数据库，收集了 2007 年至 2014 年全国医疗保健安全网络监测的手术程序和相关气候条件的入院和随访记录。我们发现，出院后，每日最大降水量每增加 10 厘米，SSI 的发生几率就会增加 1.09 倍，而每克/千克单位的相对湿度增加，SSI 风险的发生几率就会增加 1.03 倍。我们发现，美国东南部地区面临与气候变化相关的 SSI 的风险最高，在高排放假设下，到 2060 年，SSI 预计将增加 3%。我们的研究结果描述了气候对 SSI 的影响，以及与气候变化相关的 SSI 在全美范围内的潜在负担。
