Evidence based guidelines for prevention of Ventilator-associated Pneumonia among Intensive Care Unit Staff Nurses

Abstract

Ventilator associated pneumonia is a common hospital acquired pneumonia in ventilated patients. VAP occurs in 28% of patients who receive mechanical ventilation, where its rate of occurrence varies with the duration of mechanical ventilation. The aim of the study was to assess impact of educational intervention on knowledge and practice of intensive care staff nurses regarding evidence based guidelines for prevention of ventilatorassociated pneumonia (VAP) among patients admitted in intensive care units of New Civil Hospital, Surat. Evaluative (quantitative) research approach and pre experimental with one group pretest post test research design was adopted for this study. A sample of 30 staff nurses working in intensive care unit of New Civil Hospital, Surat were selected by non-probability purposive sampling technique. Knowledge level was assessed by selfstructured knowledge questionnaire and practice level by observational checklist. The data was analyzed by using descriptive and inferential statistics. The results revealed that maximum subjects 46.66% were between age group 20–30 years, majority 90% were female, about 80% had done GNM, 53% were having between 5–10 years of working experience. The mean posttest knowledge score was 20.67 higher than the mean pretest knowledge score 15 and mean posttest practice score was 11.8 higher than the mean pretest practice score 6.4. The karl pearson's correlation value computed between knowledge and practice scores of staff nurses r was 0.9, this indicates the existence of moderately positive correlation between knowledge and practice score. The calculated chi-square value for knowledge and practice scores with selected socio demographic variables revealed that there was no statistical association. Furthermore the study revealed that educational intervention program on evidence based guidelines for prevention of ventilator associated pneumonia was effective in improving knowledge and positive practice regarding VAP.
