Cost-effectiveness of a domestic violence and abuse training and support programme in primary care in the real world: updated modelling based on an MRC phase IV observational pragmatic implementation study.

ABSTRACT: 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.

Project description:BACKGROUND:Violence against women and girls is a public health epidemic. Campus-based research has found bystander programmes show promise as effective primary prevention of sexual violence. However, evidence regarding domestic violence and abuse bystander prevention specifically, and in community settings generally, is still in development. Further, research has predominantly emanated from the US. Examining proof of concept in differing cultural contexts is required. This study evaluates the feasibility and potential for effectiveness of a domestic violence and abuse bystander intervention within UK general communities-Active Bystander Communities. METHODS:Participants recruited opportunistically attended a three-session programme facilitated by experts in the field. Programme feasibility was measured using participant attendance and feedback across nine learning objectives. Myth acceptance, bystander efficacy, behavioural intent and bystander behaviours were assessed using validated scales at baseline, post-intervention, and four-month follow-up. Results were examined for potential backlash. Analyses used a paired sample t-test and effect size was quantified with Cohen's d. RESULTS:58/70 participants attended all programme sessions. Participant feedback consistently rated the programme highly and significant change (p???0·001) was observed in the desired direction across behavioural intent, bystander efficacy, and myth acceptance scores at post and follow-up. Effect size was generally large and, with the exception of Perception of Peer Myth Acceptance, improved at follow-up. Backlash was minimal. CONCLUSIONS:To our knowledge this is the first UK-based study to examine the potential of bystander intervention as a community-level intervention for domestic violence and abuse. Findings are promising and indicate the translatability of the bystander approach to domestic violence and abuse prevention as well as community contexts. This is likely to be of great interest to policymakers and may help shape future community-based interventions. Further research is now needed using experimental designs engaging diverse community audiences.

Project description: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 1000 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% CI 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% CI 0.13 to 6.84, p?=?0.959). New DVA cases recorded significantly increased with an incident rate ratio of 1.27 (95% CI 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% CI 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.

Project description:BackgroundDomestic violence and abuse (DVA) is common and damaging to health. UK national guidance advocates a multi-agency response to DVA, and domestic homicide reviews consistently recommend improved information-sharing between agencies. Identification of patients experiencing DVA in general practice may come from external information shared with the practice, such as police incident reports and multi-agency risk assessment conference (MARAC) reports. The aim of this study was to explore the views of general practitioners (GPs) and the police about sharing reports about DVA with GPs.MethodsQualitative semi-structured interviews were conducted with GPs, police staff and a partnership manager. Participants were located across England and Wales. Thematic analysis was undertaken.ResultsInterviews were conducted with 23 GPs, six police staff and one former partnership manager. Experiences of information-sharing with GPs about DVA varied. Participants described the relevance and value of external reports to GPs to help address the health consequences of DVA and safeguard patients. They balanced competing priorities when managing this information in the electronic medical record, namely visibility to GPs versus the risk of unintended disclosure to patients. GPs also spoke of the judgements they made about exploring DVA with patients based on external reports, which varied between abusive and non-abusive adults and children. Some felt constrained by short general practice consultations. Some police and GPs reflected on a loss of control when information about DVA was shared between agencies, and the risk of unintended consequences. Both police and GPs highlighted the importance of clear information and a shared understanding about responsibility for action.ConclusionGPs regarded external reports about DVA as relevant to their role, but safely recording this information in the electronic medical record and using it to support patients required complex judgements. Both GPs and police staff emphasised the importance of clarity of information and responsibility for action when information was shared between agencies about patients affected by DVA.

Project description:Identification and Referral to Improve Safety (IRIS) is a training and support programme to improve the response to domestic violence and abuse (DVA) in general practice. Following a pragmatic cluster-randomised trial, IRIS has been implemented in over 30 administrative localities in the UK. The trial and local evaluations of the IRIS implementation showed an increase in referrals from general practice to third sector DVA services with a variation in the referral rates within and across practices. Using Normalisation Process Theory (NPT), we aimed to understand the reasons for such variability by identifying factors that influenced the implementation of IRIS in the National Health Service (NHS). We conducted a mixed-method process evaluation which included: (a) a case study (100 hr of participant observation, 19 interviews); (b) a survey (n = 118); (c) qualitative analysis of free-text comments from the survey; (d) qualitative interviews (n = 8); (e) document review (n = 44). Data were collected from NHS and third sector staff across five London boroughs from August 2015 to December 2017, analysed descriptively and thematically and triangulated using the NPT constructs coherence, cognitive participation, collection action and reflexive monitoring. The survey showed wide variation in the extent to which practice staff saw IRIS as a normal part of their daily work. Qualitative data and documents illuminated drivers of DVA work, implementation barriers and suggested solutions. The drivers were related to individual professional's characteristics and relationships. The barriers were linked to the differing sense-making and legitimisation of DVA work and differing contexts between the NHS and third sector. Solutions were adaptations to IRIS relative to these contextual differences. The suggested solutions can be used to update IRIS commissioning guidance, training for trainers and training for general practice. The updates should reflect the importance of ongoing support of IRIS from practice leads and commissioners, extended funding periods for IRIS and continuity of the IRIS team.

Project description:BACKGROUND:Exposure 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. METHODS:We 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. RESULTS:Our 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. CONCLUSIONS:This 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.

Project description:BACKGROUND:The police attend numerous domestic violence events each year, recording details of these events as both structured (coded) data and unstructured free-text narratives. Abuse types (including physical, psychological, emotional, and financial) conducted by persons of interest (POIs) along with any injuries sustained by victims are typically recorded in long descriptive narratives. OBJECTIVE:We aimed to determine if an automated text mining method could identify abuse types and any injuries sustained by domestic violence victims in narratives contained in a large police dataset from the New South Wales Police Force. METHODS:We used a training set of 200 recorded domestic violence events to design a knowledge-driven approach based on syntactical patterns in the text and then applied this approach to a large set of police reports. RESULTS:Testing our approach on an evaluation set of 100 domestic violence events provided precision values of 90.2% and 85.0% for abuse type and victim injuries, respectively. In a set of 492,393 domestic violence reports, we found 71.32% (351,178) of events with mentions of the abuse type(s) and more than one-third (177,117 events; 35.97%) contained victim injuries. "Emotional/verbal abuse" (33.46%; 117,488) was the most common abuse type, followed by "punching" (86,322 events; 24.58%) and "property damage" (22.27%; 78,203 events). "Bruising" was the most common form of injury sustained (51,455 events; 29.03%), with "cut/abrasion" (28.93%; 51,284 events) and "red marks/signs" (23.71%; 42,038 events) ranking second and third, respectively. CONCLUSIONS:The results suggest that text mining can automatically extract information from police-recorded domestic violence events that can support further public health research into domestic violence, such as examining the relationship of abuse types with victim injuries and of gender and abuse types with risk escalation for victims of domestic violence. Potential also exists for this extracted information to be linked to information on the mental health status.
