Summary: | Oral nutritional supplements (ONS) are commonly used to treat malnutrition. Many patients are prescribed ONS without assessment of nutritional status. This conflicts with prescribing guidelines and has considerable cost implications. This scoping review aimed to provide an overview of interventions to improve appropriate ONS prescribing in primary care.
A systematic scoping review was undertaken. PubMed, EMBASE and CINAHL were searched from inception to September 2018. Studies meeting inclusion criteria had to: evaluate interventions targeting ONS prescribing in primary care; use a comparative evaluation; be published in English. Two reviewers independently screened abstracts and extracted data relating to study design, intervention characteristics, outcome assessments and key findings. Extracted data were collated using figures, tables and accompanying descriptive summaries.
10 studies met inclusion criteria. All studies involved uncontrolled before-and-after designs. Interventions ranged from dietitian-led reviews of patients prescribed ONS to transfer of ONS prescribing privileges from general practitioners to dietitians. Post-intervention results showed improvements in ONS prescribing based on study-specific assessments of prescribing appropriateness and absolute reductions in prescribing, as well as potential cost-savings.
This review provides a detailed overview of interventions aimed at improving appropriate ONS prescribing in primary care. Interventions evaluated to date most commonly involved dietitians. However, use of controlled experimental design was lacking. Lack of consistency in defining appropriate ONS prescribing and assessment outcomes was apparent. Future research should attend to rigour during intervention development, evaluation and reporting in order to generate findings which could inform relevant policy and practice. |
