无论是否由畸形、创伤、感染、肿瘤或缺血性疾病引起，横掌趾骨截肢提供了在进行重大近端截肢之前保护肢体的功能手段。与住院手术相比，住院再入院率相似，对于较易受损的患者，尤其是老年人，预防不必要的住院具有益处。本研究调查了住院并不需要再入院的老年患者在接受门诊横掌趾骨截肢术后的差异。通过对特定于横掌趾骨截肢术的CPT 28805进行筛选，对老年患者进行了ACS NSQIP数据库分析。比较了患者的人口统计学特征、病史、手术特点和社会/功能决定因素，以区分未住院和再入院的患者群。统计学显著性阈值设定为p ≤ 0.05。总体上，老年患者接受门诊横掌趾骨截肢术的再入院率为19%。在患者人口统计学特征、过去病史或手术状况方面，两组之间没有统计学显著差异。与未再入院组相比，保持一定程度的功能依赖的老年患者再入院的可能性要高出3.41倍（p = 0.006）。在接受门诊横掌趾骨截肢术的老年患者中，应在手术前考虑其功能状态。对于在日常生活中不能自立的患者，应予以更多关注。随着人口的老龄化，了解与老年人群相关的社会环境非常重要，以预防再入院。© 2023. 由Elsevier Inc.出版。

Whether secondary to deformity, traumatic injury, infection, neoplasm, or ischemic disease, the transmetatarsal amputation provides a functional means of limb preservation prior to major proximal amputation. With similar readmission rates following inpatient and outpatient surgery, prevention of an unnecessary admission among vulnerable patients, specifically geriatrics, proves beneficial. This investigation examines differences among geriatric patients admitted and not requiring readmission following outpatient transmetatarsal amputation. An ACS NSQIP database analysis following filtering for CPT 28805, specific for transmetatarsal amputations, was performed among geriatric patients. Patient demographic, medical history, operative characteristics, and social/functional determinants were compared between the no admission and readmission cohorts. The threshold for statistical significance was set at p ≤ 0.05. Overall, a 19% readmission rate was reported among geriatric patients who underwent an outpatient transmetatarsal amputation. No statistically significant difference among patient demographics, past medical history, or surgical presentation was found between cohorts. Geriatric patients that maintained some level of functional dependence were 3.41 times more likely to be readmitted than the non-readmission cohort (p = 0.006). Among geriatric patients undergoing outpatient transmetatarsal amputation, function status should be taken into account prior to surgery. Greater consideration should also be given to patients who do not maintain independence during their activities of daily living. As the population continues to age, recognizing social circumstances associated with the geriatric population proves important in preventing readmission.Copyright © 2023. Published by Elsevier Inc.
