A Cluster Randomised Trial to Support Screening and Treatment for Unhealthy Alcohol Use in Aboriginal Community Controlled Health Services.

Background: Evidence-based management of unhealthy alcohol use in primary care has been advocated since 1979. Few studies focus on improving implementation of alcohol screening and treatment in Indigenous primary care, despite greater harms from alcohol in that population group. Aims: To examine: (i) approaches used to improve screening and treatment for unhealthy alcohol use in primary care internationally; (ii) the effects of the 24-months’ support offered to 22 Aboriginal Community Controlled Health Services on screening and treatment for unhealthy alcohol use. Methods: Study 1 (systematic review) describes strategies to improve alcohol screening and treatment in primary care and investigates if they employed elements of continuous quality improvement. Studies 2 and 3 test the effect of the 24-month support on: (i) rates of screening and any alcohol treatment provision; (ii) recommended frequency of screening. Results: Study 1 found that few implementation strategies focussed on screening and treatments for the full spectrum of unhealthy alcohol use. About 20% of the studies employed the essential elements of continuous quality improvement. Study 2 showed significant improvement in the odds of screening. The effect on provision of any treatment as well as on individual treatment types was not clear and varied greatly between participating services. Study 3 was not able to show significant increases in the odds of first-time or annual screening. There were 841 (2%) clients who were screened four or more times annually. Conclusion: Support provided to Aboriginal Community Controlled Health Services over 24 months can improve the rates of alcohol screening. More focus is needed on screening frequency for individual clients. Further support for the delivery and accurate recording of alcohol treatment is needed. The thesis discusses practice, policy, and research recommendations for future directions in improving screening and treatment for unhealthy alcohol use

Support for Aboriginal health services in reducing harms from alcohol : 2-year service provision outcomes in a cluster randomized trial

Background and aims There is a higher prevalence of unhealthy alcohol use among Indigenous populations, but there have been few studies of the effectiveness of screening and treatment in primary health care. Over 24 months, we tested whether a model of service-wide support could increase screening and any alcohol treatment. Design Cluster-randomized trial with 24-month implementation (12 months active, 12 months maintenance). Setting Australian Aboriginal Community Controlled primary care services. Participants Twenty-two services (83 032 clients) that use Communicare practice software and see at least 1000 clients annually, randomized to the treatment arm or control arm. Intervention and comparator Multi-faceted early support model versus a comparator of waiting-list control (11 services). Measurements A record (presence = 1, absence = 0) of: (i) Alcohol Use Disorders Identification Test—Consumption (AUDIT-C) screening (primary outcome), (ii) any-treatment and (iii) brief intervention. We received routinely collected practice data bimonthly over 3 years (1-year baseline, 1-year implementation, 1-year maintenance). Multi-level logistic modelling was used to compare the odds of each outcome before and after implementation. Findings The odds of being screened within any 2-month reference period increased in both arms post-implementation, but the increase was nearly eight times greater in early-support services [odds ratio (OR) = 7.95, 95% confidence interval (CI) = 4.04–15.63, P < 0.001]. The change in odds of any treatment in early support was nearly double that of waiting-list controls (OR = 1.89, 95% CI = 1.19–2.98, P = 0.01) but was largely driven by decrease in controls. There was no clear evidence of difference between groups in the change in the odds of provision of brief intervention (OR = 1.95, 95% CI = 0.53–7.17, P = 0.32). Conclusions An early support model designed to aid routine implementation of alcohol screening and treatment in Aboriginal health services resulted in improvement of Alcohol Use Disorders Identification Test—Consumption screening rates over 24 months of implementation, but the effect on treatment was less clear

'The drug survey app' : a protocol for developing and validating an interactive population survey tool for drug use among Aboriginal and Torres Strait Islander Australians

Background: Disadvantage and transgenerational trauma contribute to Aboriginal and Torres Strait Islander (Indigenous) Australians being more likely to experience adverse health consequences from alcohol and other drug use than non-Indigenous peoples. Addressing these health inequities requires local monitoring of alcohol and other drug use. While culturally appropriate methods for measuring drinking patterns among Indigenous Australians have been established, no similar methods are available for measuring other drug use patterns (amount and frequency of consumption). This paper describes a protocol for creating and validating a tablet-based survey for alcohol and other drugs (“The Drug Survey App”). Methods: The Drug Survey App will be co-designed with stakeholders including Indigenous Australian health professionals, addiction specialists, community leaders, and researchers. The App will allow participants to describe their drug use fexibly with an interactive, visual interface. The validity of estimated consumption patterns, and risk assessments will be tested against those made in clinical interviews conducted by Indigenous Australian health professionals. We will then trial the App as a population survey tool by using the App to determine the prevalence of substance use in two Indigenous communities. Discussion: The App could empower Indigenous Australian communities to conduct independent research that informs local prevention and treatment efforts

A systematic review of approaches to improve practice, detection and treatment of unhealthy alcohol use in primary health care: A role for continuous quality improvement

Background: Unhealthy alcohol use involves a spectrum from hazardous use (exceeding guidelines but no harms) through to alcohol dependence. Evidence-based management of unhealthy alcohol use in primary health care has been recommended since 1979. However, sustained and systematic implementation has proven challenging. The Continuing Quality Improvement (CQI) process is designed to enable services to detect barriers, then devise and implement changes, resulting in service improvements. Methods: We conducted a systematic review of literature reporting on strategies to improve implementation of screening and interventions for unhealthy alcohol use in primary care (MEDLINE EMBASE, PsycINFO, CINAHL, the Australian Indigenous Health InfoNet). Additional inclusion criteria were: (1) pragmatic setting; (2) reporting original data; (3) quantitative outcomes related to provision of service or change in practice. We investigate the extent to which the three essential elements of CQI are being used (data-guided activities, considering local conditions; iterative development). We compare characteristics of programs that include these three elements with those that do not. We describe the types, organizational levels (e.g. health service, practice, clinician), duration of strategies, and their outcomes. Results: Fifty-six papers representing 45 projects were included. Of these, 24 papers were randomized controlled trials, 12 controlled studies and 20 before/after and other designs. Most reported on strategies for improving implementation of screening and brief intervention. Only six addressed relapse prevention pharmacotherapies. Only five reported on patient outcomes and none showed significant improvement. The three essential CQI elements were clearly identifiable in 12 reports. More studies with three essential CQI elements had implementation and follow-up durations above the median; utilised multifaceted designs; targeted both practice and health system levels; improved screening and brief intervention than studies without the CQI elements. Conclusion: Utilizing CQI methods in implementation research would appear to be well-suited to drive improvements in service delivery for unhealthy alcohol use. However, the body of literature describing such studies is still small. More well-designed research, including hybrid studies of both implementation and patient outcomes, will be needed to draw clearer conclusions on the optimal approach for implementing screening and treatment for unhealthy alcohol use.

Community-based alcohol education intervention (THEATRE) study to reduce harmful effects of alcohol in rural Sri Lanka: design and adaptation of a mixed-methods stepped wedge cluster randomised control trial

Introduction Alcohol consumption is a leading cause of mortality, morbidity and adverse social sequelae in Sri Lanka. Effective community-based, culturally adapted or context-specific interventions are required to minimise these harms. We designed a mixed-methods stepped wedge cluster randomised control trial of a complex alcohol intervention. This paper describes the initial trial protocol and subsequent modifications following COVID-19.Methods and analysis We aimed to recruit 20 villages (approximately n=4000) in rural Sri Lanka. The proposed intervention consisted of health screening clinics, alcohol brief intervention, participatory drama, film, and public health promotion materials to be delivered over 12 weeks.Following disruptions to the trial resulting from the Easter bombings in 2019, COVID-19 and a national financial crisis, we adapted the study in two main ways. First, the interventions were reconfigured for hybrid delivery. Second, a rolling pre–post study evaluating changes in alcohol use, mental health, social capital and financial stress as the primary outcome and implementation and ex-ante economic analysis as secondary outcomes.Ethics and dissemination The original study and amendments have been reviewed and granted ethical approval by Rajarata University of Sri Lanka (ERC/2018/21—July 2018 and February 2022) and the University of Sydney (2019/006). Findings will be disseminated locally in collaboration with the community and stakeholders.The new hybrid approach may be more adaptable, scalable and generalisable than the planned intervention. The changes will allow a closer assessment of individual interventions while enabling the evaluation of this discontinuous event through a naturalistic trial design. This may assist other researchers facing similar disruptions to community-based studies.Trial registration The trial is registered with the Sri Lanka Clinical Trials Registry; https://slctr.lk/trials/slctr-2018-037
