Social concordance can affect the doctor–patient interaction and possibly also referral behaviour.Aim To investigate the association of gender concordance and age concordance on referral rates in primary care in The Netherlands.Design & setting Electronic health records data (n = 24 841) were used from 65 GPs in The Netherlands, containing referral information, which was combined with demographics of GPs and patients to investigate factors associated with referral likelihood.Method Health records covered 16 different symptoms and diagnoses, categorised as ‘gender sensitive’, ‘age sensitive’, ‘both age and gender sensitive’, or ‘neutral’ based on Delphi consensus. Multi-level logistic regressions were performed to calculate the associations of gender and age concordance with referral status.Results Overall, 16.8% of patients were referred to a medical specialist. The female–male dyad (GP–patient) was associated with a higher referral likelihood (odds ratio [OR] 1.14; 95% confidence interval [CI] = 1.02 to 1.27; P = 0.02) compared with the female–female dyad. Gender discordance was associated with a higher referral likelihood regarding consultations involving ‘gender-sensitive’ symptoms and diagnoses (OR 1.21; CI = 1.02 to 1.44; P = 0.03), and in duo and group practices (OR 1.08; 95% CI = 1.00 to 1.16; P = 0.05). Age concordance was not a significant predictor of referrals in the main model nor in subgroup analyses.Conclusion Gender discordance was associated with a higher likelihood of referring. This study adds to the evidence that gender concordance affects decisions to refer, particularly with respect to symptoms and diagnoses that can be regarded as ‘gender sensitive’.
