Physicians, pharmacists and take-home naloxone: What practices? The SINFONI study.

ABSTRACT

OBJECTIVE: For several years, both the French Addictovigilance Network and French health authorities have consistently emphasized the need to provide opioid users with take-home naloxone (THN), the specific antidote for opioid overdoses. In March 2022, the French Health Authority recommended systematically assessing the appropriateness of prescribing THN to all opioid users, regardless of the context, and identified 8 high-risk situations. However, at present, THN distribution remains limited, particularly among primary care healthcare professionals. This study, conducted by the Pays de la Loire Centre for Evaluation and Information on Drug Dependence-Addictovigilance and supported by the Regional Health Agency, aims to explore healthcare professionals' practices and perceptions of these high-risk situations. METHODS: An ad-hoc questionnaire was distributed via mail by the project's regional institutional partners to the target healthcare professionals pharmacists, general practitioners (GPs), physicians practicing in specialities other than general medicine (SPs algologists, psychiatrists and addictologists). It was completed online from 20/10/2022 to 30/12/2022. RESULTS: Out of the 355 participants (158 pharmacists, 167 GPs and 30 SPs), nearly all were managing patients on opioids. In total, 47.7% of physicians and 27.8% of pharmacists reported experiencing difficulties in dealing with the risk of overdose when prescribing or dispensing opioids to their patients. In the 12months preceding the study, only 8 pharmacists and 34 physicians had prescribed/dispensed THN, primarily due to a lack of awareness of its existence (52% of pharmacists and 72% of physicians) and challenges in addressing the eight overdose risk situations listed by the HAS (ranging from 54% to 83% for all professionals). The best-trained healthcare professionals were those who prescribed the most THN (P<0.001). CONCLUSION: The identification of barriers related to THN distribution in the regional SINFONI study, conducted among primary care healthcare professionals managing patients on opioids, highlights the need to develop a training tool specifically tailored for these professionals.
