GP preferences for discussing statin deprescribing: a discrete choice experiment

Deprescribing (planned, supervised discontinuation) of statins may be considered in some older persons. This should be carefully discussed between patients and GPs.

We examined GPs' preferences for discussing statin deprescribing by conducting a discrete choice experiment (DCE) sent to a stratified random sample of 500 Danish GPs. Attributes were discussion topics (goals of therapy, evidence on statin use in older persons, adverse effects, uncertainty), and levels were the depth of the discussion topics (none, brief, detailed). We used mixed logistic regression for analysis.

A total of 90 GPs (mean age 48, 54% female, mean 11 years in practice) completed the DCE. There was substantial variability in which topics GPs felt were most important to discuss; however, GPs generally preferred a brief discussion of topics to detailed ones. The most important discussion topic appeared to be goals of therapy. GPs felt a brief discussion of evidence was important but not a detailed one, while adverse effects and uncertainty were felt to be less important to discuss.

GPs prefer brief discussions on a range of topics when discussing statin deprescribing but have differing views on which topics are most important. For deprescribing communication tools to be useful to GPs in clinical practice, they may need to focus on brief coverage of the range of relevant topics. Future work should evaluate patient preferences, and opportunities for education and training for GPs on deprescribing communication.
