Surgical site infections (SSI) are a costly problem. The purpose of this study was to determine the rate of infection and identify patient and technical risk factors for SSI in an orthopaedic ambulatory surgical center. Over 11,000 consecutive orthopaedic surgeries over 5 years were reviewed for SSI as well as demographic, medical, and surgical risk factors. Nearly 400 noninfected patients served as statistical controls. The overall infection rate was 0.33%, which compares favorably to previous studies of outpatient surgery and appears to be substantially lower than SSI rates previously reported for inpatient orthopaedic surgery. Male sex, smoking, and diabetes demonstrated significantly higher risk for infection. Surgery time and duration of anesthesia administration were also associated statistically with SSI. A history of cancer, hypertension, or thyroid problems were all associated with higher but statistically insignificant risk of SSI. Patient age and number of past surgeries were equal in the SSI and control groups.
手术部位感染（SSI）是一个代价高昂的问题。本研究的目的是确定感染率，并识别骨科门诊手术中心SSI的患者和技术风险因素。对5年期间超过11000例连续的骨科手术进行了SSI以及人口统计学、医学和手术风险因素的评估。近400名未感染患者作为统计对照。总体感染率为0.33%，与先前关于门诊手术的研究相比具有优势，且似乎显著低于先前报道的住院骨科手术的SSI率。男性、吸烟和糖尿病表现出明显更高的感染风险。手术时间和麻醉给药持续时间在统计学上也与SSI相关。癌症、高血压或甲状腺问题病史均与较高但无统计学意义的SSI风险相关。SSI组和对照组的患者年龄和既往手术次数相当。
