Decrease in provider stigma is associated with improved quality health indicators among individuals receiving methadone in primary care centers in Ukraine

Abstract

Introduction

People who inject drugs experience poor health and social outcomes which improve with opioid agonist therapies like methadone, yet provider stigma may influence healthcare utilization. In Ukraine, integrating methadone into primary care centers (PCCs) provides an opportunity to examine provider stigma and its impact on patient outcomes.

Methods

This sub-analysis included patients randomized to receive methadone in PCCs as part of an implementation trial in which the control group received methadone in specialty addiction clinics in Ukraine. Methadone integration in PCCs was supported through continuous tele-education for providers. Provider stigma towards people who inject drugs, methadone, and attitudes towards evidence-based practices were assessed at baseline, 12, and 24 months using standardized scales (range 1–10). Patient-level outcomes were measured bi-annually over 24 months using a quality health indicator (QHI) score, a percentage of guideline-concordant primary and specialty health services accessed. Linear mixed-effects models examined the changes in provider stigma and attitudes, and the association of these measures with patient outcomes.

Results

The sample included 583 patients and the 112 providers in 24 clinics. Provider fear and stereotypes toward people who inject drugs improved significantly, by 0.6 (95 % CI 0.2–1.1) and 0.4 points (95 % CI 0.1–0.8), respectively, as did preference for methadone over abstinence-based treatment (0.7 points, 95 % CI 0.2–1.1). A 1-point improvement in provider prejudice correlated with a 7.0-point increase (95 % CI: 1.1–13.0) in patient primary care QHI scores at 12 months, while improved attitudes towards evidence-based practices were associated with an 8.3-point increase (95 % CI: 1.1–13.0). Preference for methadone maintenance over abstinence was associated with a 3.7-point increase (95 % CI: 0.6–6.7) in specialty care QHI scores at 12 months, and reduced stereotypes were associated with a 10.9-point increase (95 % CI: 1.2–20.7) at 24 months.

Conclusions

Integrating methadone into PCCs with the support of provider tele-education may reduce provider stigma, particularly fear and stereotypes, toward people who inject drugs and methadone maintenance. Reducing provider stigma has the potential to improve patient outcomes through increased access to preventive care and screenings.
