Introduction Practice-Based Small Group Learning (PBSGL) is a system for continuing professional development introduced into Wessex Region Defence Primary Healthcare (DPHC) as the Salisbury Plain PBSGL group in 2012. This is a mixed intraprofessional group comprising general practitioners (GPs), GP trainers, general practice specialist registrars (GPSTs) and general duties medical officers (GDMOs).

Methods An anonymised online questionnaire and thematic analysis was undertaken to assess the educational impact of PBSGL in such a mixed-role group reflecting military general practice.

Results A positive effect of PBSGL was demonstrated and further enhanced by the intraprofessional composition. Positive peer support effects were demonstrated for all members of the cohort regardless of role.

Conclusion PBSGL is an essential pillar for supporting all doctors working within DPHC. Further qualitative evaluation of cohorts of GDMOs, GPSTs and mixed-role groups as well as the development of standardised questionnaires is recommended.
