Impact of room service on nutritional intake, plate and production waste, meal quality and patient satisfaction and meal costs: A single site pre-post evaluation.

Abstract

Room service is a patient-focused foodservice model gaining interest in Australian hospitals following demonstrated patient and organisational benefits. This study aimed to compare nutritional intake, waste, patient satisfaction, meal costs and meal quality between a bought-in, thaw-retherm foodservice model and a cook-fresh, on-demand room service model at a large tertiary public hospital. A retrospective analysis of quality assurance data compared thaw-retherm to room service. Nutritional intake and plate waste were measured using a visual intake analysis tool; production waste was measured using weighted analysis methodology; patient satisfaction was measured using a validated patient satisfaction survey; meal quality was assessed using a validated meal quality audit tool, and meal costs were obtained from hospital finance reports. Independent sample t-tests or nonparametric equivalent (Mann-Whitney U-test) for continuous variables and Pearson's Chi-square for categorical data were applied for comparative purposes. Average energy and protein intake, as well as percentage requirements met, improved between thaw-retherm and room service (4320 kJ/day vs 7265 kJ/day; 42.4 g/day vs 82.5 g/day; and 46% vs 80.7%; 49.9% vs 98.4%; all P < .001. Reductions in plate waste (40% vs 15%) and production waste (15% vs 5.6%, P < .001) were observed and food costs decreased by 9% with room service. Meal quality audit results improved, and patient satisfaction increased with % respondents satisfied increasing from 75.0% to 89.8% (χ2 9.985[2]; P=.007) for room service. This research demonstrates significant improvements in patient and organisational outcomes with room service compared to a thaw-retherm model in a large public hospital.
