BackgroundChildren’s exposure to domestic violence is a type of child maltreatment, yet many general practice clinicians remain uncertain of their child safeguarding responsibilities in the context of domestic violence. We developed an evidence-based pilot training on domestic violence and child safeguarding for general practice teams. The aim of this study was to test and evaluate its feasibility, acceptability and the direction of change in short-term outcome measures.MethodsWe used a mixed method design which included a pre-post questionnaire survey, qualitative analysis of free-text comments, training observations, and post-training interviews with trainers and participants. The questionnaire survey used a validated scale to measure participants’ knowledge, confidence/ self-efficacy, and beliefs/ attitudes towards domestic violence and child safeguarding in the context of domestic violence.ResultsEleven UK general practices were recruited (response rate 55%) and 88 clinicians attended the pilot training. Thirty-seven participants (42%) completed all pre-post questionnaires and nine were interviewed. All training sessions were observed. All six trainers were interviewed. General practice clinicians valued the training materials and teaching styles, opportunities for reflection and delivery by local trainers from both health and children’s social services. The training elicited positive changes in total outcome score and knowledge and confidence/ self-efficacy sub scores which remained at 3-month follow up. However, the mean sub score of beliefs and attitudes did not change and the qualitative results were mixed. Two interviewees described changes in their clinical practice. Participants’ suggestions for improving the training included incorporating more ethnic and class diversity in the material, using cases with multiple socio economic disadvantages, and addressing multi-agency collaboration in the context of changing and under-resourced services for children.ConclusionsThe pilot training for general practice on child safeguarding in the context of domestic violence was feasible and acceptable. It elicited positive changes in clinicians’ knowledge and confidence/ self-esteem. The extent to which clinical behaviour changed is unclear, but there are indications of changes in practice by some clinicians. The pilot training requires further refinement and evaluation before implementation.

Objectives To synthesise evidence on the acceptable identification and initial response to children’s exposure to intimate partner violence (IPV) from the perspectives of providers and recipients of healthcare and social services. Design We conducted a thematic synthesis of qualitative research, appraised the included studies with the modified Critical Appraisal Skills Programme checklist and undertook a sensitivity analysis of the studies scored above 15. Data sources We searched eight electronic databases, checked references and citations and contacted authors of the included studies. Eligibility criteria We included qualitative studies with children, parents and providers of healthcare or social services about their experiences of identification or initial responses to children’s exposure to IPV. Papers that have not been peer-reviewed were excluded as well as non-English papers. Results Searches identified 2039 records; 11 studies met inclusion criteria. Integrated perspectives of 42 children, 212 mothers and 251 professionals showed that sufficient training and support for professionals, good patient-professional relationship and supportive environment for patient/clients need to be in place before enquiry/disclosure of children’s exposure to IPV should occur. Providers and recipients of care favour a phased enquiry about IPV initiated by healthcare professionals, which focuses on ‘safety at home’ and is integrated into the context of the consultation or visit. Participants agreed that an acceptable initial response prioritises child safety and includes emotional support, education about IPV and signposting to IPV services. Participants had conflicting perspectives on what constitutes acceptable engagement with children and management of safety. Sensitivity analysis produced similar results. Conclusions Healthcare and social service professionals should receive sufficient training and ongoing individual and system-level support to provide acceptable identification of and initial response to children’s exposure to IPV. Ideal identification and responses should use a phased approach to enquiry and the WHO Listen, Inquire about needs and concerns, Validate, Enhance safety and Support principles integrated into a trauma-informed and violence-informed model of care.

Objectives To evaluate the cost-effectiveness of the implementation of the Identification and Referral to Improve Safety (IRIS) programme using up-to-date real-world information on costs and effectiveness from routine clinical practice. A Markov model was constructed to estimate mean costs and quality-adjusted life-years (QALYs) of IRIS versus usual care per woman registered at a general practice from a societal and health service perspective with a 10-year time horizon. Design and setting Cost–utility analysis in UK general practices, including data from six sites which have been running IRIS for at least 2 years across England. Participants Based on the Markov model, which uses health states to represent possible outcomes of the intervention, we stipulated a hypothetical cohort of 10 000 women aged 16 years or older. Interventions The IRIS trial was a randomised controlled trial that tested the effectiveness of a primary care training and support intervention to improve the response to women experiencing domestic violence and abuse, and found it to be cost-effective. As a result, the IRIS programme has been implemented across the UK, generating data on costs and effectiveness outside a trial context. Results The IRIS programme saved £14 per woman aged 16 years or older registered in general practice (95% uncertainty interval −£151 to £37) and produced QALY gains of 0.001 per woman (95% uncertainty interval −0.005 to 0.006). The incremental net monetary benefit was positive both from a societal and National Health Service perspective (£42 and £22, respectively) and the IRIS programme was cost-effective in 61% of simulations using real-life data when the cost-effectiveness threshold was £20 000 per QALY gained as advised by National Institute for Health and Care Excellence. Conclusion The IRIS programme is likely to be cost-effective and cost-saving from a societal perspective in the UK and cost-effective from a health service perspective, although there is considerable uncertainty surrounding these results, reflected in the large uncertainty intervals.

BackgroundExposure to domestic violence and abuse (DVA) results in a reduction of women’s use of regular contraceptives. This evidence suggests that women exposed to DVA are more likely to have unprotected sexual intercourse and therefore may use more emergency contraception (EC) than those women who are not exposed to DVA. We aimed to test this hypothesis through evaluating the evidence for an association between exposure to DVA and use of EC.MethodsWe systematically searched eight electronic databases from inception until December 2017, checked references and citations, and contacted corresponding authors. Primary studies that evaluated the association between exposure to DVA and use of EC were included. Two reviewers were involved in screening, data extraction, quality assessment and analysis. We evaluated the quality of included studies with the adapted Newcastle-Ottawa Scale. We used tables and descriptive text to summarise and synthesise the data. Odds ratios (ORs) and 95% confidence intervals (CIs) for each estimate of the association between DVA and use of EC were plotted on a forest plot.ResultsOur search retrieved 1216 records of which six studies with 15,297 women were included. Five studies were observational; one study included intervention on the outcome (advance supply of EC). All studies were at high risk of bias. Four studies provided evidence of an association between DVA and EC use – ORs from 1.51 (95% CI 1.13, 2.02) to 6.50 (95% CI 4.15, 10.17). Two studies found no evidence of a such association – ORs 0.46 (95% CI 0.11, 1.96) and 0.76 (95% CI 0.29, 1.98). The latter differed by how the authors recruited participants, measured EC use and adjusted for confounders.ConclusionsThis systematic review provides some evidence of increased use of EC among women exposed to DVA. Request for EC can indicate possible exposure to DVA. Therefore, each consultation for EC could be an appropriate context for clinical enquiry about DVA and signposting/referral to specialist DVA services.Protocol registrationPROSPERO CRD42017058221.

BackgroundDomestic violence and abuse remains a major health concern. It is unknown whether the improved healthcare response to domestic violence and abuse demonstrated in a cluster randomised controlled trial of IRIS (Identification and Referral to Improve Safety), a complex intervention, including general practice based training, support and referral programme, can be achieved outside a trial setting. Aim: To evaluate the impact over four years of a system wide implementation of IRIS, sequentially into multiple areas, outside the setting of a trial.MethodsAn interrupted time series analysis of referrals received by domestic violence and abuse workers from 201 general practices, in five northeast London boroughs; alongside a mixed methods process evaluation and qualitative analysis. Segmented regression interrupted time series analysis to estimate impact of the IRIS intervention over a 53-month period. A secondary analysis compares the segmented regression analysis in each of the four implementation boroughs, with a fifth comparator borough.DiscussionThis is the first interrupted time series analysis of an intervention to improve the health care response to domestic violence. The findings will characterise the impact of IRIS implementation outside a trial setting and its suitability for national implementation in the United Kingdom.
