Project Details


A four centre survey of adult ICU nurses decision-making around gastric residual volume measurement to guide enteral feeding

Key findings

Two hundred and seventy-three responses were obtained across four intensive care units with acceptable response rates for most [Unit 1 74 /127 = 58.2%; Unit 2 87/129 =67.4%; Unit 3 77/120= 64.1%; Unit 4 35/168 = 20.8%]. Most (243/273 (89%) reported measuring GRV 4-6 hourly, with most (223/273 82%) reporting the main reason was to assess feed tolerance or intolerance and 37/273 13.5% saying their unit protocol required it. In terms of factors affecting decision-making, volume obtained was the most important factor, followed by the condition of the patient, with aspirate colour and appearance less important. When asked how they would feel about not measuring gastric residual volume routinely, the majority (78.2%) of nurses felt worried (140/273 = 51.2%) or very worried (74/273 = 27%).
