Economic Impact of Implementing Malnutrition Screening and Nutritional Management in Older Adults in General Practice

Objectives Malnutrition is a common and significant public health problem, especially for older adults, as the consequences are costly. National guidelines (NICE CG32/QS24) highlight the need to identify and manage malnutrition, the implementation of which was deemed high impact to produce cost savings. The 'Malnutrition Pathway', endorsed by NICE and other professional bodies, is a practical evidence-based guide to help community healthcare professionals (HCP) to implement guidance on malnutrition management. Published evaluations of its use are needed. Design This service evaluation in older adults assessed the impact of implementing the 'Malnutrition Pathway' on health care use and costs, as well as the acceptability of the management strategies and effect on malnutrition risk. Setting 5 GP surgeries in Gloucestershire. Participants 163 older adults (80 +/- 9 years) with a range of primary diagnoses, living in their own home, were screened using the Malnutrition Universal Screening Tool ('MUST') (n50 low risk (LR); n41 medium risk (MR); n72 high risk (HR)). All patients were managed according to risk (LR: no further management; MR: dietary advice (DA); and HR: DA plus two oral nutritional supplements (ONS) (1 serve 300kcal, 18g protein; 125ml). Measurements At each review (6weeks, 3 and 6 months), 'MUST' score, compliance and satisfaction to their management plan were recorded. Healthcare use was collected from GP records 6 months before and after implementation of the pathway. A simple cost analysis was completed. Results Implementing appropriate management of malnutrition led to significant reductions in hospital admissions (p=0.028), length of hospital stay (p=0.05), GP visits (p=0.007) and antibiotic prescriptions (p=0.05). Over 6 months, the costs to manage malnutrition (HCP time, ONS) were more than offset by the savings associated with these reductions in health care use (per patient savings of -395.64 pound MR+HR; -997.02 pound HR). The proportion of individuals at risk of malnutrition reduced over time, and patients reported being satisfied with the DA (97%) and ONS (96%), consuming 90% of their ONS prescription. Conclusion Managing malnutrition significantly reduces healthcare use, with a positive budget impact, in older malnourished patients in primary care. This represents an opportunity to improve patient care with benefit on health care spend.
