Background:In Australia, general practitioners (GPs) are recognised as an essential source of postpartum care. However, there remains a paucity of research pertaining to this, and in particular, to that of GP trainees (in Australia, termed 'registrars'). Previous post-graduate experience in obstetrics and gynaecology (O&G) is not a prerequisite for GP training, and thus, it is imperative that vocational training provides adequate exposure to postpartum consultations.Aim: To investigate the prevalence and associations of Australian GP registrars' (trainees') experience in postpartum care. Materials and Methods:A cross-sectional study employing data from the Registrar Clinical Encounters in Training (ReCEnT) project. ReCEnT is an ongoing cohort study where GP registrars record 60 consecutive consultations mid-way through each training term. The outcome variable was postpartum problem/diagnosis (compared to all other problems/diagnoses). The independent variables included registrar, practice, patient, consultation, clinical and educational factors. Analyses employed univariate and multivariable regression. Results: Analysis included 2234 registrars (response rate 96.1%), 289 594 consultations, and 453 786 problems/diagnoses. Postpartum care (897) comprised 0.2% (95% CI: 0.19-0.21) of all problems/diagnoses in 0.3% (95% CI: 0.27-0.31) of all consultations. Significant multivariable associations included registrar's gender (female) and obtainment of post-graduate O&G qualifications. Postpartum consultations were longer and resulted in more learning goals being generated. Discussion: An overall low prevalence was established. Both male registrars, and those without pre-existing O&G qualifications, may have particularly limited experience. These findings should inform educational policy and practice regarding postpartum care experience in general practice training.
