目的：：研究优质护理模式对老年患者呼吸机相关性肺炎发生率的影响。方法：选取2014年10月-2015年6月我科进行呼吸机机械通气治疗，采用优质护理模式的50例老年患者，设为观察组；回顾性调查2014年10月以前我科进行呼吸机机械通气治疗，采用常规护理模式的50例老年患者，设为对照组，比较两组老年患者呼吸机相关性肺炎的发生率及患者护理服务满意度。结果：观察组老年患者呼吸机相关性肺炎的发生率明显低于对照组，差异有统计学意义(P<0.05)，护理服务满意度显著高于对照组(P<0.05)。结论：优质护理模式能预防及降低老年患者呼吸机相关性肺炎的发生，提高患者对护理服务的满意度，值得临床推广。“,”objective: to study the quality of nursing model for elderly patients with ventilator associated pneumonia incidence. Methods: choose in October 2014 - June 2015 I branch of breathing machine mechanical ventilation therapy, USES the high quality of the nursing mode of 50 cases of elderly patients, as observation group; Retrospective investigation before October 2014 my breathing machine mechanical ventilation therapy, the conventional nursing mode of 50 cases of elderly patients, as control group, compared two groups the incidence of ventilator associated pneumonia in elderly patients and patients with nursing service satisfaction.
