Case-control study for evaluation of cost and outcome of nosocomial surgical site infection in primary hip arthroplasty during a period of 5 years. Mean hospitalization time in the orthopedic service was 54 days for cases, and 13 days for control (p<0.05). Mean hospitalization time in Intensive Care Unit (ICU) was 1.1 days for cases. There were 0.83 post primary surgery interventions in cases, and a mean of 2.08 bacteriological cultures in each case. Controls didn't have hospitalizations in the ICU surgical reinterventions nor cultures necessary. The mean cost of infected patients was US $: 6,174.8. Mean cost in controls was US $: 2,354.7. The excess of cost due to infections was US $: 2,354.7 on the average. Outcomes in cases were: normal function 30.8%; moderate or serious sequelae 46.2%; death rate 15, 4%. The measured parameters contributed to raise case costs, and they caused an unsatisfactory outcome for two third of the patients.
一项为期5年的病例对照研究，旨在评估初次髋关节置换术中医院手术部位感染的成本和结局。骨科服务中病例的平均住院时间为54天，对照组为13天（p<0.05）。重症监护病房（ICU）中病例的平均住院时间为1.1天。病例在初次手术后平均有0.83次干预措施，且每个病例平均有2.08次细菌培养。对照组无需在ICU住院，也无需进行手术再干预或培养。感染患者的平均费用为6,174.8美元。对照组的平均费用为2,354.7美元。感染导致的平均额外费用为2,354.7美元。病例的结局为：功能正常30.8%；中度或重度后遗症46.2%；死亡率15.4%。所测量的参数导致病例成本增加，并且导致三分之二的患者结局不理想。
