| description | Background: Overuse of medical care is a pervasive problem. Studies using hypothetical scenarios suggest that physicians’ risk literacy influences medical decisions; real-world correlations, however, are lacking. We sought to determine the association between physicians’ risk literacy and their real-world prescriptions of potentially hazardous drugs, accounting for conflicts of interest and perceptions of benefit–harm ratios in low-value prescribing scenarios. Setting and sample: Cross-sectional study—conducted online between June and October 2023 via field panels of Sermo (Hamburg, Germany)—with a convenience sample of 304 English general practitioners (GPs). Methods: GPs’ survey responses on their treatment-related risk literacy, conflicts of interest and perceptions of the benefit–harm ratio in low-value prescribing scenarios were matched to their UK National Health Service records of prescribing volumes for antibiotics, opioids, gabapentin and benzodiazepines and analysed for differences. Results: 204 GPs (67.1%) worked in practices with ≥6 practising GPs and 226 (76.0%) reported 10–39 years of experience. Compared with GPs demonstrating low risk literacy, GPs with high literacy prescribed fewer opioids (mean (M): 60.60 vs 43.88 prescribed volumes/1000 patients/6 months, p=0.016), less gabapentin (M: 23.84 vs 18.34 prescribed volumes/1000 patients/6 months, p=0.023), and fewer benzodiazepines (M: 17.23 vs 13.58 prescribed volumes/1000 patients/6 months, p=0.037), but comparable volumes of antibiotics (M: 48.84 vs 40.61 prescribed volumes/1000 patients/6 months, p=0.076). High-risk literacy was associated with lower conflicts of interest (ϕ = 0.12, p=0.031) and higher perception of harms outweighing benefits in low-value prescribing scenarios (p=0.007). Conflicts of interest and benefit–harm perceptions were not independently associated with prescribing behaviour (all ps >0.05). Conclusions and relevance: The observed association between GPs with higher risk literacy and the prescription of fewer hazardous drugs suggests the importance of risk literacy in enhancing patient safety and quality of care. |
