Pilot Study to Investigate Enteral Feeding Practices and the Incidence of Underfeeding Among Mechanically Ventilated Critically Ill Patients at a Specialist Tertiary Care Hospital in Saudi Arabia.

Background: Enteral nutrition (EN) is an essential therapeutic intervention. Many studies internationally have reviewed feeding practices in intensive care units (ICUs) and recorded the incidence of underfeeding in these settings, yet none were performed in the Middle East, including Saudi Arabia. The purpose of the study is to assess the adequacy of EN delivery and investigate the enteral feeding practices in the ICU at a specialized tertiary care hospital in Saudi Arabia. Methods: In this observational study, we prospectively monitored energy and protein delivery for 6 consecutive days in critically ill patients. Malnutrition was assessed by Nutrition Risk Screening (NRS‐2002) scores. Underfeeding was identified by comparing the intake against the calculated requirements. Patients were categorized into early and late EN starters to investigate whether the time of EN initiation impacts the cumulative nutrition intake. Results: This study included 43 patients. About 44% (19 of 43) of the patients were malnourished on admission to ICU, and the prevalence of underfeeding was >90%. The median cumulative intake of energy and protein was 39% and 31% of the estimated requirements, respectively. Patients who started early EN had statistically higher cumulative energy and protein intake (P‐value =.00). Patients treated with inotropes received less energy and protein compared with those who did not receive inotropes (P‐value =.00). Higher NRS‐2002 score was associated with fewer ventilation‐free hours (r = −0.369, P‐value =.045). Conclusion: Protein underfeeding remains a significant problem in ICU settings. The time of EN initiation plays a major role in determining when the nutrition requirements will be met. Therefore, it is crucial to implement effective feeding protocols to ensure early initiation of EN when permissible. [ABSTRACT FROM AUTHOR]
