Effect of evidence-based nursing on ventilator-associated pneumonia in patients with mechanical ventilation

Objective To explore the clinical effect of evidence-based nursing in ventilator-associated pneumonia (VAP).Methods One hundred and sixty patients with mechanical ventilation in our ICU from January 2011 to June 2013 were randomly divided into the observation group and the control group.The control group received the traditional nursing,and the observation group received evidence-based nursing on the basis of the routine nursing.The time of invasive ventilation,the duration of ventilation,the off-line time,the occurrence time of VAP,and the incidence and mortality rates of VAP were compared between two groups.Results The time of invasive ventilation,the duration of ventilation,the off-line time,the occurrence time of VAP in the observation group were respectively (3.3 ± 0.6),(10.3 ± 3.8),(2.6 ± 4.3),(9.2 ± 2.8) d,and were significantly lower or later than (5.6 ± 3.1),(13.1 ± 3.4),(6.5 ± 4.8),(4.8 ± 2.7) d in the control group,and the differences were statistically significant (t =2.58,2.63,2.86,2.79,respectively; P ＜0.05).The incidence and mortality rates of VAP in the observation group were respectively 16.9％ and 10.4％,and were significantly lower than 48.1％ and 34.9％ in the control group,and the differences were statistically significant (x2 =5.36,4.93,respectively; P ＜ 0.01).Conclusions Evidence-based nursing can significantly shorten the time of invasive ventilation,the duration of ventilation and the off-line time; and can also effectively delay and reduce the occurrence of VAP.
