摘要
目的探讨外科术后患者发生切口感染的手术室相关影响因素及采取干预措施后的效果评价,为预防患者术后感染提供有效方法。方法选取2014年1月-2016年12月期间于医院接受外科手术患者2210例作为研究对象,其中2014年1月-2015年6月期间1026患者未实施干预作为对照组,2015年7月-2016年12月1184例患者实施干预为研究组,对患者发生术后切口感染情况及与手术室相关影响因素进行单因素和多因素Logistic回归分析,并对两组患者干预前后的切口感染率、平均住院时间及住院费用进行比较分析。结果外科术后患者发生切口感染的主要手术室因素为手术时间、手术切口、非流层手术、手术参观人数和手术室空气细菌含量;对照组感染率为7.60%(78/1026),实施干预后研究组感染率为2.20%(26/1184),两组比较差异有统计学意义(P<0.05);研究组患者的住院时间(7.87±3.060)周、住院费用(10.62±2.39)万元少于对照组的(12.94±5.63)周、(15.32±3.57)万元,(均P<0.05)。结论外科手术后患者发生切口感染的感染率较高,其中与手术室相关影响因素有手术时间、手术切口、非流层手术、手术参观人数和手术室空气细菌含量,根据影响因素实施针对性的防治策略能够有效降低切口感染率,同时缩短患者的住院时间和减少住院费用。
OBJECTIVE To explore the operating room-related factors for surgical incision infections and observe the effect of intervention measures so as to provide guidance for effective prevention of postoperative infections. METHODS A total of 2210 patients who received surgical procedures in hospitals from Jan 2014 to Dec 2016 were recruited as the study objects, 1026 patients who were not treated with interventions from Jan 2014 to Jun 2015 were assigned as the control group, while 1184 patients who were treated with interventions from Jul 2015 to Dec 2016 were set as the study group.The prevalence of postoperative incision infections was investigated, the univari- ate analysis and multivariate logistic regression analysis were performed for the operating room-related influencing factors, and the incidence of incision infections, average length of hospital stay and hospitalization cost were ob- served and compared between the two groups of patients before and after the intervention.RESULTS The operation duration, surgical incision, non-laminar flow surgery, number of surgical participants and bacterial colony counts in air were the major operating room-related factors for the postoperative incision infections.The incidence rate of infection was 7.60% （78/1026） in the control group, 2.20± （26/1184） in the study group after the intervention, and there was significant difference between the two groups （P〈0.05）.The length of hospital stay of the study group was （7.87±3.060） weeks, significantly shorter than （12.94±5.63） weeks of the control group; the hospi- talization cost of the study group was （10.62±2.39） ten yuan of the control group （all P^0.05）.CONCLUSION The incidence of incision infections is high in the patients after surgical procedures, the operating room-related influencing factors include the operation duration, surgical incision, non-laminar flow surgery, number of surgical participants and bacterial colony counts in air.It is necessa- ry to take targeted prevention and treatment countermeasures according to the influencing factors so as to effec- tively reduce the incidence of incision infections, shorten the length of hospital stay and reduce the hospitalization cost.
