Effectiveness of ventilator bundle on prevention of ventilator associated pneumonia among Patients on mechanical ventilator at selected hospitals, Salem

A study was done to Evaluate the Effectiveness of Ventilator Bundle on Prevention of Ventilator Associated Pneumonia among Patients on Mechanical Ventilator at Selected Hospitals, Salem. A quantitative evaluative research approach with quasi experimental post test only design was adopted for the study. Through Non- Probability Convenience Sampling Technique, 40 patients on mechanical ventilator were selected, among them 20 from Sri Gokulam Hospital were selected as experimental group and 20 from Vinayaka Mission Kirupananda Variyar Speciality Hospital were selected as control group. Demographic variables were collected by using a semi- structured interview schedule and their post test level of ventilator associated pneumonia was assessed by Clinical Pulmonary Infection Score (CPIS). In experimental group the investigator provided ventilator bundle immediately after endotracheal intubation and continued for three days. The findings revealed that in experimental group 6(30%) of them were in 21-30 years and in control group 7(35%) of them were between 51- 60 years of age. Majority of the patients in experimental 14(70%) and control 15(75%) group were male. Most of the patients in experimental 9(45%) and control group 7(35%) were ventilated due to CNS Disease problems. Most of the patients had undergone 2nd hourly suctioning in experimental group 12(60%) where as in control group 8(40%) patients had undergone 3rd hourly suctioning. Half of the patients in experimental 10(50%) and control group 11(55%) had the history of smoking habit. During the post test, in experimental group 5(25%) patients did not develop infection, 11(55%) patients had mild infection and 4(20%) patients have severe infection. In control group 7(35%) patients had mild infection and 13(65%) patients had severe infection. In experimental group the post test mean score was 1.7±1.04 and in control group the post test mean score was 2.95±1.76. The mean difference was 31. The calculated ‘t’ value was 5.20 which was greater than the table value 2.02, significant at p ≤ 0.05 level. Hence the research hypothesis H1 was retained. There was no association in experimental and control group on prevention of ventilator associated pneumonia with their selected demographic variables. This shows that the ventilator bundle was effective in preventing the ventilator associated pneumonia among patients on mechanical ventilator
