Being Explicit About Decisions: Prescribe Medications for Opioid Use Disorder on the Basis of Proven Effectiveness, Not Beliefs

The Experience of Implementing a Low-Threshold Buprenorphine Treatment Program in a Non-Urban Medical Practice

BACKGROUND

To respond to the U.S. opioid crisis, new models of healthcare delivery for opioid use disorder treatment are essential. We used a qualitative approach to describe the implementation of a low-threshold buprenorphine treatment program in an independent, community-based medical practice in Ithaca, NY.

METHODS

We conducted 17 semi-structured interviews with program staff, leadership, and external stakeholders. Then we analyzed these data using content analysis. We used purposeful sampling aiming for variation in job title for program staff, and in organizational affiliation for external stakeholders.

RESULTS

We found that opening an independent medical practice allowed for low-threshold buprenorphine treatment with less regulatory oversight, but state-certification was ultimately required to ensure financial sustainability. Relying on health insurance reimbursement alone led to funding shortfalls and additional funding sources were also required. The practice's ability to build relationships with licensed substance use treatment programs, community organizations, the legal system, and government agencies in the region differed depending on how much these entities supported a harm reduction philosophy compared to abstinence-based treatment. Finally, expanding the practice to a second location in a different region, co-located with a syringe service program, required adapting to a new cultural and political environment.

CONCLUSION

The results from this study provide insight about the challenges that independent medical practices might face in delivering low-threshold buprenorphine treatment. They support policy efforts to address the financial burdens associated with providing low-threshold buprenorphine therapy and inform the external relationships that other providers would need to consider when delivering novel treatment models.

The cascade of care for opioid use disorder: a retrospective study in British Columbia, Canada

BACKGROUND AND AIMS

The 'cascade of care' framework, measuring attrition at various stages of care engagement, has been proposed to guide the public health response to the opioid overdose public health emergency in British Columbia, Canada. We estimated the cascade of care for opioid use disorder and identified factors associated with care engagement for people with opioid use disorder (PWOUD) provincially.

DESIGN

Retrospective study using a provincial-level linkage of four health administrative databases.

SETTING AND PARTICIPANTS

All PWOUD in BC from 1 January 1996 to 30 November 2017.

MEASUREMENTS

The eight-stage cascade of care included diagnosed PWOUD, ever on opioid agonist treatment (OAT), recently on OAT, currently on OAT and retained on OAT: ≥ 1, ≥ 3, ≥ 12 and ≥ 24 months). Health-care use, homelessness and other demographics were obtained from physician billing records, hospitalizations, and drug dispensation records. Receipt of income assistance was indicated by enrollment in Pharmacare Plan C.

FINDINGS

A total of 55 470 diagnosed PWOUD were alive at end of follow-up. As of 2017, a majority of the population (n = 39 456; 71%) received OAT during follow-up; however, only 33% (n = 18 519) were currently engaged in treatment and 16% (n = 8960) had been retained for at least 1 year. Compared with those never on OAT, those currently engaged in OAT were more likely to be aged under 45 years [adjusted odds ratio (aOR) = 1.75, 95% confidence interval (CI) = 1.64, 1.89], male (aOR = 1.72, 95% CI = 1.64, 1.82), with concurrent substance use disorders (aOR = 2.56, 95% CI = 2.44, 2.70), hepatitis C virus (HCV) (aOR = 1.22, 95% CI = 1.14, 1.33) and either homeless or receiving income-assistance (aOR = 4.35, 95% CI = 4.17, 4.55). Regular contact with the health-care system-either in out-patient or acute care settings-was common among PWOUD not engaged in OAT, regardless of time since diagnosis or treatment discontinuation.

CONCLUSIONS

People with opioid use disorder in British Columbia, Canada show high levels of out-patient care prior to diagnosis. Younger age, male sex, urban residence, lower income level and homelessness appear to be independently associated with increased opioid agonist treatment engagement.
