Knowledge Regarding Evidence-Based Care of Mechanically Ventilated Patients Among Intensive Care Unit Nurses: A Cross-Sectional Study

Abstract

Background: Mechanical ventilation is a critical procedure used for the treatment of patients experiencing respiratory distress in the ICU. The nursing staff is an important participant in the management of ventilated patients by means of constant monitoring, complication prevention, evidence-based practices application, and assistance in weaning from the ventilator. Adequate knowledge of evidence-based practices of ventilation is required for the safety of patients.

Objectives: To assess the knowledge regarding care of mechanically ventilated patients among intensive care unit nurses and to determine its association with selected socio-demographic variables.

Methods: A quantitative descriptive cross-sectional study was conducted among 150 intensive care nurses working in a tertiary care hospital in Bengaluru, India. Participants were selected using a non-probability convenience sampling technique. Data were collected using a validated structured questionnaire consisting of 45 multiple-choice questions covering six domains of evidence-based ventilator care. Data were analysed using descriptive and inferential statistics.

Results: Among the participants, 38.0% demonstrated inadequate knowledge, 32.7% had moderate knowledge, and 29.3% had adequate knowledge. Nurses showed higher knowledge in general concepts and patient assessment, whereas knowledge deficits were identified in ventilator troubleshooting, ventilator-associated pneumonia prevention, and management of ventilator-related complications. Significant associations were found between knowledge level and age, educational qualification, and ICU experience (P < .05).

Discussion: The study identified knowledge gaps among ICU nurses regarding care of mechanically ventilated patients, especially in advanced technical aspects. Continuous professional education and competency-based training are recommended to strengthen critical care nursing practice and improve patient outcomes. Further research can focus on assessing nurses' practical competency and clinical performance related to ventilator management.
