Where is the evidence base: NMP in primary care?

A review of the literature on non-medical prescribingĂ‚ (NMP) in primary care that looked for evidence of patient outcomes has found that most such studies were undertaken in the UK, and that there are ‘substantial gaps’ in the knowledge base that could inform evidence-based policy making.

The authors identified 17 empirical studies providing patient outcome evidence of NMP in primary care, with only two looking at clinical outcomes. Some papers were surveys, had qualitative designs, few participants, or reported on prescribing from limited formularies, and the authors comment that, ‘the strength of evidence they provide on the whole is limited’.

NMP in primary care does seem to improve: ‘patients’ understanding of treatment, condition and self-care and provides a better level of care’, was well accepted by patients and professionals, and improved access to medicines and healthcare professionals. Other indicators of effectiveness such as clinical outcomes or patient safety had very limited evidence, and papers on health economics and efficiency were also lacking.
