Mealtime care and dietary intake in older psychiatric hospital inpatient: A multiple case study

Aims To investigate the energy and protein adequacy of meals and dietary intake of older psychiatric inpatients and describe patient and mealtime factors potentially influencing intake. Design Multiple case studies. Methods Psychiatric inpatients aged 65 years and older, admitted to a single mental health ward during the 6-week study period (April-May 2019) were eligible for inclusion. Dietary intake was observed for two consecutive days each week (minimum four observation days). Visual plate waste methods were used to estimate patients' dietary intake at mealtimes, with energy and protein intake calculated using known food composition data and compared with estimated requirements. Medical records were reviewed weekly to collect information on potential factors related to intake and mealtime care. Data from all sources were first summarized in a case record for within-case analysis using descriptive statistics, followed by cross-case analysis. Results Eight participants (five men, age 67-90 years, two underweight and one overweight, and four requiring some mealtime assistance) had 5-12 days of observation data recorded. Three met their estimated daily energy and protein requirements throughout the study period, while the remaining five participants did not. The main barriers identified as contributing to insufficient energy and protein intake were as follows: missing meals (asleep and treatment); inadequate food provided (insufficiency of the standard hospital menu); and need for increased mealtime assistance. Conclusion Poor dietary intake may be common among older psychiatric patients, suggesting that they may also need nursing and multidisciplinary nutrition care interventions shown to effectively prevent and treat malnutrition in other older inpatient groups. Impact Older psychiatric patients experience similar nutrition and mealtime issues to other older inpatients. This study highlights the need for nurses and the multidisciplinary team to ensure patients order and receive adequate food, especially when they miss meals and that they receive proactive mealtime assistance.

Automated summary

This study investigated the energy and protein adequacy of meals and dietary intake of older psychiatric inpatients and identified factors influencing intake. Poor dietary intake was common among the participants, with barriers such as missing meals, inadequate food provided, and the need for increased mealtime assistance. The findings highlight the importance of nurses and multidisciplinary teams ensuring patients receive adequate food and proactive mealtime assistance.
