【摘要】 目的:评估基于PDCA模式对改良哮喘预测指数(mAPI)阳性喘息婴幼儿实施哮喘预防干预措施的临床效果。方法:选取本院2019年6月-2020年6月mAPI阳性的婴幼儿共204例,按随机数字表法分为试验组与对照组,每组102例。试验组给予基于PDCA模式预防干预,对照组给予常规干预。控制良好者停止干预,控制不良者继续下一轮的干预。比较两组干预后TRACK评估控制良好率、控制不良患儿的肺功能异常率。结果:试验组第一次TRACK评估控制良好率为58.8%,对照组控制良好率37.2%,差异有统计学意义(χ~2=9.505,P=0.002)。对控制不良者试验组再次进行PDCA,第二次TRACK评估控制良好率66.6%,明显高于对照组的23.5%,差异有统计学意义(χ~2=19.655,P<0.000 1);干预6个月对仍控制不良者行肺功能检查,试验组总异常率为42.9%,明显低于对照组89.8%,差异有统计学意义(χ~2=14.649,P=0.000 66)。结论:基于PDCA模式对mAPI阳性的婴幼儿实施哮喘预防干预措施管理模式,能有效提高患儿的临床症状控制率,减轻反复发作带来的治疗负担,降低肺功能损害发生率,值得在临床中推广使用。更多还原

【Abstract】 Objective:To evaluate the clinical effect of preventive measures for asthma in wheezing infants with positive mAPI based on PDCA model.Method:A total of 204 cases of mAPI positive infants in our hospital from June 2019 to June 2020 were selected and divided into the experimental group and the control group according to random number table method,with 102 cases in each group.The experimental group was given preventive intervention based on PDCA mode,while the control group was given routine intervention.The well-controlled stopped the intervention,the poorly-controlled continued the next round of intervention.After intervention,the rate of good TRACK evaluation control and the rate of abnormal lung function in poor control were compared between the two groups.Result:The good control rate of the first TRACK evaluation was 58.8% in the experimental group and 37.2% in the control group,the difference was statistically significant (χ~2=9.505,P=0.002).PDCA was carried out again for the group with poor control,and the rate of good control was 66.6% in the second TRACK evaluation,which was significantly higher than the rate of good in the control group of 23.5%,the difference was statistically significant (χ~2=19.655,P<0.000 1).Pulmonary function examination was performed for the group with poor control for half a year after intervention,and which showed that the total abnormality rate in the experimental group was 42.9%,significantly lower than 89.8% in the control group,the difference was statistically significant (χ~2=14.649,P=0.000 66).Conclusion:The management mode of preventive intervention measures for mAPI positive infants based on PDCA model can effectively improve the clinical symptom control rate of children,reduce the burden of treatment caused by repeated attacks,and reduce the incidence of lung function damage,which is worthy of clinical promotion.更多还原
