摘要
目的应用分类回归树模型(CART)构建手术室护士发生焦虑结局的预测指标。方法选取2017年3月-2020年6月任职中国人民解放军海军第971医院的手术室护士284名,应用分类回归树模型对基线集数据加以评估,确定诱发部队医院手术室护士焦虑的风险因素,,计算不同风险因素的贡献率。将预测集作为预测结果评估方法,以明确诱发护士的焦虑自评量表(SAS)评分达到焦虑标准的风险因子。结果单因素分析结果证实,周工作时间、婚姻状态、有无子女、心理韧性调查表(CD-RISC)评分、年龄、学历的差异有统计学意义(P值均<0.05)。对护士SAS得分的分类回归树分析可见,周工作时间、婚姻状况、子女情况、CD-RISC评分、年龄进人模型,形成6个节点,其中同时存在离异、周工作时间>45 h者SAS评分最高。结论引起手术室护士焦虑的风险因子由每周工作时间、婚姻状况、子女情况、心理韧性、年龄5项构成,护理管理人员可应用手术室护士焦虑风险因子对焦虑结局进行提前预估,并实施合理千预,有助于降低护理人员的焦虑程度。
Objective To construct the prediction index of anxiety outcome of nurses in operating room by using classified regression tree model.Methods A total of 284 operating room nurses in 971th Hospital of Navy of Chinese People's Liberation Army from March 2017 to June 2020 were selected to evaluate the baseline set data by using the classification regression tree model to determine the risk factors inducing anxiety of operating room nurses in military hospitals,and calculate the contribution rate of different risk factors.The prediction set was used as the evaluation method of prediction results to determine the risk factors that induced nurses'self rating Anxiety Scale(SAS)score to reach the anxiety standard.Results The results of single factor analysis confirmed that the weekly working time,marital status,having children,CD-RISC score,age educational background were statistically significant(all P<0.05).The SAS score split regression tree analysis of nurses showed that the weekly working time,marital status,children's situation,CD-RISC score,age entry model,formed 6 nodes,among which there were divorce,weekly working time>45 h and the highest score.Conclusion The risk:factors of nurses anxiety in operating room were composed of five items:working hours,marital status,children's condition,psychological elasticity and age.Nursing managers can use the risk factors of nurses anxiety in operating room to predict the anxiety outcome in advance and carry out timely and reasonable intervention,which can help to reduce the anxiety degree of nursing staff.
