The Relationship between Mechanically Ventilated Patients' Outcomes and Body Mass Index at Intensive Care Unit.

Background: Mechanical ventilation is a life-saving intervention commonly used in intensive care units to support patients with respiratory failure. However, the outcomes of mechanically ventilated patients can vary significantly based on numerous factors, including underlying comorbidities, severity of illness, and nutritional status. Body mass index (BMI), has emerged as a potential predictor of clinical outcomes in critically ill patients. Aim: This study aimed to assess the relationship between mechanically ventilated patients outcomes and body mass index at intensive care unit. Design: A descriptive correlational research design was used. Setting: the study was conducted in the Surgical Intensive care units at surgical hospitals of Ain Shams University hospital in Egypt. Subjects: A purposive sample of (60) patients from both genders in surgical intensive care units. Tools: Three tools were used to collect data, Tool (I): Patients Structured Interviewing Questionnaire which included two parts:- Part I: Patients Demographic Characteristics. Part II: Patients Medical data. Tool (II): Burns Wean Assessment Program (BWAP) checklist. Tool (III): Sequential Organ Failure Assessment Questionnaire (SOFA score). Results: The study finding revealed that, 46.7% of the studied patients were in category of overweight and 53.3% of the studied patients their total score of Burns wean assessment was difficult. 75% of the studied patients total score of SOFA was severe, which the patients had severe organ dysfunction. Conclusion: there was highly statistically significant negative correlation between the studied patients’ total BWAP, BMI and total SOFA score with p- value (0.001). Recommendations: A collaborative approach involving respiratory therapists, nurses, and physicians can enhance patient care during the weaning process. Regular team meetings to discuss patient progress. Regular team meetings to discuss patient progress may improve outcomes.
