Mealtime and patient factors associated with meal completion in hospitalised older patients: An exploratory observation study.

ABSTRACT

AIMS AND OBJECTIVES: To examine mealtime and patient factors associated with meal completion among hospitalised older patients. We also considered contextual factors such as staffing levels and ward communication. BACKGROUND: Sub-optimum nutrition is a modifiable risk factor for hospital associated decline (HAD) in older patients. Yet, the quality of mealtime experiences can be overlooked within ward routinised practice. DESIGN: Cross sectional, descriptive observation study. METHODS: We undertook structured observation of mealtimes examining patient positioning, mealtime set-up and feeding assistance. The outcome was meal completion categorised as 0, 25%, 50%, 75% or 100%. Data were collected on patient characteristics and ward context. We used mixed-effects ordinal regression models to examine patient and mealtime factors associated with higher meal completion producing odds ratios (OR) and 95% confidence intervals (CI). The study was reported as per STROBE guidelines. RESULTS: We included 60 patients with a median age of 82 years (IQR 76-87) and clinical frailty score of 5 IQR (4-6). Of the 279 meals, 51% were eaten completely, 6% three quarters, 15% half, 18% a quarter and 10% were not eaten at all. Mealtime predictors with a weak association with less-meal completion were requiring assistance, special diets, lying in bed, and red tray (indicator of nutrition risk), but were not statistically significant. Significant patient-level factors were higher values for frailty (OR 0.34 [0.11-1.04]) and Malnutrition Universal Screening Tool (OR 0.22 [0.08-0.62]). The average nurse-to-patient ratio was 15.5. CONCLUSION: Patient factors were the strongest predictors for meal completion, but mealtime factors had a subtle influence. The nursing teams' capacity to prioritise mealtimes above competing demands is important as part of a comprehensive nutrition strategy. RELEVANCE TO CLINICAL PRACTISE Nurses are central to optimising nutrition for frail older patients. It requires ward leadership to instil a culture of prioritising assisted mealtimes, improved communication, greater autonomy to tailor nutrition strategies and safe staffing levels.
