Self-perceived learning outcomes of academic detailing discussing rational therapy with proton pump inhibitors among general practitioners in Norway

The increasing prevalence of long-term use of proton pump inhibitors (PPIs) could reflect inappropriate prescribing. Deprescribing PPIs may lead to rebound hyperacidity and subsequent reinitiation of therapy. Education on rational PPI therapy is relevant for general practitioners (GPs).

We evaluated a Norwegian academic detailing (AD) campaign aimed at promoting rational therapy with PPIs among GPs. Electronic questionnaires were distributed before and after AD visits conducted between August 2024 and July 2025. Respondents rated their agreement with five statements assessing specific knowledge, and two statements assessing general knowledge and skills, related to PPI therapy. A seven-point Likert scale (1 = strongly disagree, 7 = strongly agree) was used to measure self-perceived learning outcomes.

Of 1,018 GPs visited, 138 (14%) completed both questionnaires. The median positive change on the Likert scale was two points for both specific knowledge and general knowledge and skills. Seventy-four percent of GPs reported a 2-4 point improvement in specific knowledge, while 64% reported a similar improvement in general knowledge and skills. Three additional statements regarding the impact of the AD visit were included in the post-visit questionnaire. The statement 'The AD visit answered all my questions regarding PPI therapy' received a median rating of 7. 'The AD visit has changed my practice with PPI' received a median rating of 6, and 'The AD visit has confirmed my practice with PPI' received a median rating of 5. No significant differences were observed between Norwegian health regions in the ratings of statements related to rational prescribing of PPIs or the AD visit.

AD addressing rational therapy with PPIs was associated with a positive self-perceived learning outcome among GPs who completed both questionnaires.
