Prescribing of nutritional supplements is increasing in general practice

Introduction of a community nutrition risk assessment tool

This article describes the introduction of a community nutrition risk assessment (CNRA) initiative in liaison with a local primary care trust (PCT). A pilot was undertaken in order to produce local evidence of the benefits of nutrition risk screening and thus gain support from the PCT for full implementation of the CNRA. The results from the pilot, which indicated that a substantial financial saving for the PCT was possible with a corresponding improvement in patient care, were sufficiently convincing for the PCT to sanction the introduction of the CNRA throughout the local community. Seven steps for success are recommended which may be of use to other healthcare professionals who are considering such a process for their own community patients or indeed any other multiprofessional initiative which requires PCT support. Such steps include identification of those who may help or hinder the process and a thorough preparation of a concise evidence-based proposal which should assist in persuading those less enthusiastic to accept and support the vision.

Patterns of prescribing of nutritional supplements in the United Kingdom

BACKGROUND AND AIMS

A large number of prescriptions are issued for nutritional supplements under British National Formulary classifications 9.4.1 (foods for special diets) and 9.4.2 (enteral feeds), but little is known about the characteristics of the patients who receive them. We used the General Practice Research Database to examine patterns of prescribing of these supplements.

METHODS

We selected patients who had been prescribed supplements under classifications 9.4.1 and 9.4.2 during 1996-1997. Descriptive statistics were used to examine how prescribing varied.

RESULTS

28644 patients received prescriptions during 1996-1997. Among the 27413 (96%) patients prescribed supplements for oral use, 14750 received supplements for enteral nutrition alone, 8122 received supplements for special diets alone and 4541 had both types of supplement. 51% of patients receiving supplements for special diets were <18 years. The commonest diagnoses among such children were milk intolerance (24%) and malnutrition (17%). 94% of patients receiving supplements for enteral nutrition were adult, 52% of whom had cancer or cardiovascular disease. Only 4% of patients had weight and height recorded prior to first prescription.

CONCLUSIONS

The GPRD provides valuable information on the characteristics of patients prescribed nutritional supplements. But because only limited data are available on their nutritional status prior to supplementation, it is hard to assess whether general practitioners are prescribing these supplements appropriately.
