Abstract
Background: Preventing nutritional decline during hospitalisation is imperative in reducing the development of complications such as malnutrition and pressure injuries. However, existing malnutrition screening and assessment tools employ a reactive rather than proactive approach, using predictors to identify inpatients who are already malnourished instead of those at risk of developing hospital-acquired malnutrition. Therefore, this review aimed to identify key contextual and individual factors contributing to nutritional deterioration and their interrelatedness, and to inform strategies for preventing hospital-acquired malnutrition.
Methods: A scoping review of five databases (Medline, CINAHL, Embase, All EBM Reviews and PsycINFO) up to June 2024 was conducted to include English-language studies that reported statistically significant risk factors for changes in nutritional status during hospitalisation. A directed acyclic graphing method was used to visualise the interlinkage between contextual and individual risk factors identified. PRISMA Extension for Scoping Reviews was followed in reporting.
Results: Of 8215 retrieved abstracts, 51 studies were included. Four contextual (ward type; food service satisfaction; medical-related mealtime interruption; nutrition care collaboration) and four individual factors (nutritional status prior admission; hospital length of stay; multimorbidity; disease acuity) were found to significantly predict nutritional decline during hospitalisation and were closely interrelated.
Conclusions: More contextual risk factors are modifiable, suggesting a need for organisational strategies to optimise collaborative nutrition care and improve patient satisfaction with hospital food services to promote early nutritional intervention, particularly within the first three days of admission and for inpatients with multimorbidity, high disease acuity, or pre-existing malnourishment.
