GPs' practices when prescribing buprenorphine in primary care: A survey among the Sentinelles network.

Introduction: France is a leading country for opioid agonist treatment providing, with a predominance of buprenorphine. General practitioners (GPs) are the main prescribers of buprenorphine, but they seem to be less involved over the last 10 years. This work is the second part of a larger study analysing buprenorphine prescribing among French GPs working in primary care, and aims to describe GPs' practices when prescribing buprenorphine.

Methods: This is a cross-sectional study conducted in France from March to July 2021 among a sample of GPs in the Sentinelles network, a national epidemiologic surveillance system. Data about the last situations of initiation and renewal of buprenorphine were collected.

Results: Among the 237 participants (34.3% response rate), 156 responded to the questionnaire about the last situation of renewal and 41 about the last situation of initiation. The last initiation occurred more than 12 months earlier for 46.3% of respondents, whereas the last renewal occurred less than 1 month ago for 68.6%. There was an over-representation of the male gender among the patients who were consulting (initiation 70.7%, renewal 68.6%). A majority of patients had an illicit opioid use disorder (initiation 78.0%, renewal 82.7%). Overall, GPs were involved in the general care of patients with opioids use disorder and in opioids harm reduction (initiation 87.8% and 82.9%, renewal 88.5% and 51.9%).

Conclusion: Among buprenorphine prescribers, initiations were infrequent unlike renewals and involved mainly illicit opioid users.
