The decision-making processes of UK general practice nurse prescribers when managing acute illness in patients with multimorbidity and polypharmacy: a qualitative study using think aloud and staged vignettes

Abstract

Aim: to investigate the decision-making processes of nurse prescribers in general practice when managing acute episodes of illness in patients with multimorbidity.

Background: nurse independent prescribers in UK general practice are facing increasing complex clinical decision-making when assessing patients presenting acutely with undifferentiated and undiagnosed conditions as multimorbidity and polypharmacy becomes increasingly common. This qualitative study investigated the decision-making processes of nurse prescribers in general practice when managing acute episodes of illness in patients with multimorbidity.

Methods: fourteen general practice nurse prescribers were recruited through purposive sampling. Think aloud in response to staged vignettes was used followed by semi-structured interviews. Thematic analysis was used to analyse think aloud and interview data.

Findings: participants were experienced nurses with a range of clinical exposure and training who mostly made appropriate diagnostic and prescribing decisions. Pockets of expertise were revealed which reflected participants’ clinical experience, but there was a high rate of referral to the GP for some vignettes. Participants’ decision-making was underpinned by both analytical and intuitive processes, the quality of which was dependent on their individual knowledge and experience. A reliance on pattern recognition, aligned to intuitive decision-making, to determine the content of the consultations was identified as an area of risk and showed all participants to be inconsistent in their identification of complex factors. Omission of these factors could have important implications for prescribing decision-making. Organizational issues such as time-limited clinics also shaped the content of participants’ consultations, encouraged a limited, problem-focused approach, and reduced the opportunity for mentorship. Comprehensive knowledge, clinical experience, and mentorship are critical to ensure nurse prescribers make optimal decisions in the context of patients with multimorbidity. A team approach to the management of acute presentations in these patients is recommended to improve patient experience and maximize nurse prescribers’ contribution to the general practice workforce.
