Drug treatment service procurement: A systematic review of models, goals, and outcomes

Aim: To explore the goals and outcomes of public procurement of drug treatment services in OECD countries. The study explores how these complex services are procured and delivered. Methods and data: A systematic review of the literature (1990-2020) identified four partly overlapping models of drug treatment service procurement that are here labelled traditional, value-based, outcome-based, and innovative. Results: Even though different forms of drug treatment services procurement are common, only 12 empirical studies that focused on procurement were found. The four models differ in their approaches to design and performance specifications and the role of competition and collaboration in the co-creation of value. Conclusions: Competition and incentives improve neither the efficiency nor the quality or the outcomes of complex drug treatment services. Whereas many studies focus on payment mechanisms, there are important research gaps that relate to the co-creation of value with and for the service-users and other stakeholders.

The Hepatitis C Awareness Through to Treatment (HepCATT) study: improving the cascade of care for hepatitis C virus-infected people who inject drugs in England

BACKGROUND AND AIMS

Previous studies have shown low rates of diagnosis and treatment of hepatitis C virus (HCV) infection in people who inject drugs (PWID). Our aims were to test the effect of a complex intervention [Hepatitis C Awareness Through to Treatment (HepCATT)] in drug and alcohol clinics-primarily, on engagement of HCV-positive PWID with therapy and, secondarily, on testing for HCV, referral to hepatology services and start of HCV treatment.

DESIGN AND SETTING

A non-randomized pilot study in three specialist addiction clinics in England comparing an intervention year (starting between September 2015 and February 2016) with a baseline year (2014), together with three control clinics.

PARTICIPANTS

Analysis included all attendees at the intervention and control specialist addiction clinics identified as PWID.

INTERVENTION

The intervention comprised the placement of a half-time facilitator in each clinic for 12 months with the brief to increase diagnosis of HCV infection within clients at those services and the engagement of diagnosed individuals with an appropriate care pathway. The facilitator undertook various activities, which could include training of key workers, direct interaction with clients, streamlining and support for hepatology appointments and introduction of dried blood-spot testing.

MEASUREMENTS

For each clinic and period, we obtained the total number of clients and, as relevant, their status as PWID, tested for HCV, known HCV-positive, engaged with HCV therapy or treated.

FINDINGS

Compared with baseline, there was strong evidence that engagement with HCV therapy in the intervention year increased (P < 0.001) more in the HepCATT centres than controls, up ⁺ 31 percentage points [95% confidence interval (CI) = 19-43] versus -12 (CI = -31 to ⁺ 6) and odds ratio (OR) = 9.99 (CI = 4.42-22.6) versus 0.35 (CI = 0.08-1.56). HepCATT centres also had greater increases in HCV testing (OR = 3.06 versus 0.78, P < 0.001), referral to hepatology (OR = 9.60 versus 0.56, P < 0.001) and treatment initiation (OR = 9.5 versus 0.74, P < 0.001).

CONCLUSIONS

Introducing a half-time facilitator into drug and alcohol clinics in England increased engagement of HCV-positive people who inject drugs with hepatitis C virus care pathways, with increased uptake also of testing, referral to hepatology and initiation of treatment.

Managing Stigma: Women Drug Users and Recovery Services

Women who use drugs are stigmatized for their drug use behavior, which marginalizes them from mainstream society. Stigmatization can be viewed as an attempt by social services to exert control. Research shows that these strategies do not work well for discouraging drug use; whereas attempts to reduce the stigma related to drug use can encourage users to stop use. Using qualitative methods and grounded theory analysis, the goal of this study is to examine (1) the stigmatization of drug use through different stages; (2) how stigmatized women drug users perceive normality; and (3) barriers and challenges to recovery. Based on in-depth interviews from 20 women who used methamphetamine, the analysis focuses on stigmatization before the initiation of drug use, difficulties related to stigma as drug users, and challenges due to stigmatization as they recover from drug use. Findings show that women are stigmatized before they use drugs, face more stigma as they use, and even during recovery society still holds onto the label of former drug user, making it difficult to avoid stigma. The findings contribute to a better understanding of how stigmatization of women drug users impacts their recovery and provides suggestions for social service and treatment providers.
