Co-located Heroin Assisted Treatment within primary care: A preliminary analysis of the implications for healthcare access, cost, and treatment delivery in the UK.

BACKGROUND: The UK is experiencing its highest rate of drug related deaths in 25 years. Poor and inconsistent access to healthcare negatively impacts health outcomes for people who use drugs. Innovation in models of care which promote access and availability of physical treatment is fundamental. Heroin Assisted Treatment (HAT) is a treatment modality targeted at the most marginalised people who use drugs, at high risk of mortality and morbidity. The first service-provider initiated HAT service in the UK ran between October 2019 and November 2022 in Middlesbrough, England. The service was co-located within a specialist primary care facility offering acute healthcare treatment alongside injectable diamorphine. METHODS: Analysis of anonymised health records for healthcare costs (not including drug treatment) took place using descriptive statistics prior and during engagement with HAT, at both three (n=15) and six (n=12) months. Primary outcome measures were incidents of wound care, skin and soft tissue infections (SSTIs), overdose (OD) events, unplanned overnight stays in hospital, treatment engagement (general and within hospital care settings) and ambulance incidents. Secondary outcome measures were costs associated with these events. RESULTS: A shift in healthcare access for participants during HAT engagement was observed. HAT service attendance appeared to support health promoting preventative care, and reduce reactive reliance on emergency healthcare systems. At three and six months, engagement for preventative wound care and treatment for SSTIs increased at the practice. Unplanned emergency healthcare interactions for ODs, overnight hospital stays, serious SSTIs, and ambulance incidents reduced, and there was an increase in treatment engagement (i.e. a reduction in appointments which were not engaged with). There was a decrease in treatment engagement in hospital settings. Changes in healthcare utilisation during HAT translated to a reduction in healthcare costs of 58% within six months compared to the same timeframe from the period directly prior to commencing HAT. CONCLUSION: This exploratory study highlights the potential for innovative harm reduction interventions such as HAT, co-located with primary care services, to improve healthcare access and engagement for a high-risk population. Increased uptake of primary healthcare services translated to reductions in emergency healthcare use and associated costs. Although costs of HAT provision are substantial, the notable cost-savings in health care should be an important consideration in service implementation planning.

More than just 'free heroin': Caring whilst navigating constraint in the delivery of diamorphine assisted treatment.

BACKGROUND: In 2020, drug related deaths in the United Kingdom (UK) reached the highest rate in over 25 years, with hospitalisations and deaths particularly impacting people who use illicit opioids such as heroin. Treatment systems are increasingly required to be innovative to engage the most vulnerable at risk from premature morbidity and mortality. Heroin Assisted Treatment (HAT) is an alternative treatment modality for people for whom more traditional forms of opioid substitution therapy, such as methadone, have been ineffective. Middlesbrough, a town in the North-East England, was home to the first service in the UK to implement HAT outside of a clinical trial setting which closed for operation in November 2022. METHODS: Qualitative in-depth interviews with patients and health care providers (n =17) involved in the delivery of HAT were undertaken during 2021. This paper focuses on the health care provider interviews, the majority of which took place remotely. Interviews were audio recorded and thematically analysed. RESULTS: Health care providers navigated multiple layers of constraint during HAT implementation and delivery. We explore this in relation to three themes: 1) Negotiating risk and safety within treatment 2) More than a prescription: care beyond diamorphine 3) Internal and external delivery barriers and impact on treatment acceptability, identity and longevity. Negotiating and managing risks of polysubstance use was a complex task. Benefits regarding access to holistic care, improved therapeutic and social relationships were recognised by practitioners. The rigorous delivery schedule was the biggest barrier to engagement. Outside the treatment room, socio-structural factors posed additional challenges. CONCLUSION: Despite some operational complexities, health care providers viewed HAT as an effective method of engaging a high risk population with drug treatment services, with holistic benefits for clients over and above the treatment of opioid dependency. Findings will inform advocacy and innovation for future HAT interventions in England.
