A European survey of enteral nutrition practices and procedures in adult intensive care units

Abstract

Aims: The aim of this survey was to gain an overview of enteral nutrition practices and procedures of European adult intensive care units and to describe current trends.

Background: Currently, little is known about nutritional practices in European intensive care units and whether they match existing guidelines.

Design: Survey.

Methods: A 51-item questionnaire about nutritional assessment and enteral feeding was distributed to 383 intensive care units in 20 countries.

Results: A total of 380 (99.2%) questionnaires were returned. Most intensive care units (86.5%, n = 320/370) did not use a nutritional risk score and 35.8% (n = 133/371) conducted daily assessments of nutritional status; body weight and serum albumin were the commonest measures. Checking the position of the feeding tube using auscultation of injected air was widespread (72.6%, n = 275/373). Most units used a clinical protocol and under half were supported by a nutritional support team.

Conclusion: There are some variations in enteral nutrition practices across European intensive care units. Involvement of nurses in performing nutritional assessments or developing clinical protocols was minimal. The use of outdated procedures for checking feeding tube placement is a concern. There is scope for further development of nutrition guidelines in European units.

Relevance to clinical practice: This study is relevant to all nurses working in critical care areas. The findings suggest that when an intensive care unit is supported by a nutritional support team it is more likely that a nutritional score will be used and nutritional assessments will be made daily. Many intensive care practices do not conform to international guidelines for enteral feeding. Nutritional assessment and the use of nutritional risk scores are areas that would benefit from further application in intensive care. This study may provide an impetus for intensive care units to review their nutrition assessment practices and to advance evidence-based guidelines, developed by multi-professional teams, which ensure the safe and effective management of patients receiving enteral nutrition.
