Abstract：
The association between the reuse of surgical masks (SMs) for multiple procedures and rates of surgical site infections (SSIs) is unclear. Hence, the purpose of this study was to determine whether a policy mandating the reuse of SMs was associated with increased SSI incidence. It was hypothesized the rate of SSIs would be significantly greater during the postimplementation period compared with the preimplementation period. Retrospective chart review of patients who underwent orthopaedic and general surgery during the 60 days before and after policy implementation was performed. Focus was on consecutive procedures performed by the same surgeon on the same day. An assessment of SSI risk factors suggested the postimplementation group was at higher risk. However, the daily use of a single SM across multiple procedures was not associated with a clinically significant increase in SSIs. Because future pandemics and public health crises may be accompanied by similar shortages, it may be possible to reuse masks in these situations without concern for increased SSI.

摘要：
用于多种手术的外科口罩（SM）的重复使用与手术部位感染（SSIs）的发生率之间的关联尚不清楚。因此，本研究的目的是确定强制重复使用SM的政策是否与SSI发生率增加相关.据推测，与实施前相比，在实施后阶段，SSIs的比率将大大增加。对政策实施前后60天接受骨科和普外科手术的患者进行回顾性图表回顾。重点是同一外科医生在同一天进行的连续手术。对SSI危险因素的评估表明，充血后人群的风险较高。然而,在多个手术中每日使用单一SM与SSIs的临床显著增加无关.因为未来的流行病和公共卫生危机可能伴随着类似的短缺，在这些情况下，可以重复使用口罩，而不必担心增加SSI。（外科骨科杂志进展33（2）：097-102，2024）。
