Background: It is unknown whether interventions known to improve the healthcare response to domestic violence and abuse (DVA) - a global health concern - are effective outside of a trial. Methods: An observational interrupted time series study in general practice. All registered women aged 16 and above were eligible for inclusion. In four implementation boroughs’ general practices, there was face-to-face, practice based, clinically relevant DVA training, a prompt in the electronic medical record, reminding clinicians to consider DVA, a simple referral pathway to a named advocate, ensuring direct access for women to specialist services, overseen by a national, health focused DVA organisation, fostering best practice. The fifth comparator borough had only a session delivered by a local DVA specialist agency at community venues conveying information to clinicians. The primary outcome was the daily number of referrals received by DVA workers per 1,000 women registered in a general practice, from 205 general practices, in all five northeast London boroughs. The secondary outcome was recorded new DVA cases in the electronic medical record in two boroughs. Data was analysed using an interrupted time series with a mixed effects Poisson regression model. Results: In the 144 general practices in the four implementation boroughs, there was a significant increase in referrals received by DVA workers - global incidence rate ratio of 30·24 (95% C.I. 20·55 to 44·77, p<0·001). There was no increase in the 61 general practices in the other comparator borough (incidence rate ratio of 0·95, 95% C.I. 0·13 to 6·84, p=0·959). New DVA cases recorded significantly increased with an incident rate ratio of 1·27 (95% C.I. 1·09 to 1·48, p<0·002) in the implementation borough but not in the comparator borough (incidence rate ratio of 1·05, 95% C.I. 0·82 to 1·34, p=0·699). Conclusions: Implementing integrated referral routes, training and system-level support, guided by a national health focused DVA organisation, outside of a trial setting, was effective and sustainable at scale, over four years (2012 to 2017) increasing referrals to DVA workers and new DVA cases’ recorded in electronic medical records.
