ABSTRACT
INTRODUCTION: In March 2020, a temporary federal regulatory exemption for opioid treatment programs (OTPs) was issued, allowing for a greater number of take-home methadone doses than was previously permitted. In the same month, to address financial sustainability, New York State (NYS) Medicaid also transitioned to a bundle reimbursement methodology for OTPs. We examined methadone dosing schedules in NYS before and after these regulatory and financing changes. METHODS: We conducted a retrospective cohort study using NYS OTP patient data from two sources: the client data system for a baseline period (February 2020) and survey data collected after regulatory and financing changes (May 2020 to August 2021, 64 weekly surveys). We compared methadone dosing schedules over time using chi-square tests and Poisson regression. RESULT: At baseline, data were available for 78% (n=77/99) of OTPs including 90.9% (n=26,225/28,839) of their enrolled patients. During the survey period, 99 OTPs completed 93.1% (n=5901/6336) of weekly surveys, with a mean statewide weekly patient census of 38,904 (SD=1214.5). Between February and May 2020, daily dosing significantly decreased from 55.4% to 16.3% of patients (-39.1 percentage points [95%CI: -39.8 to -38.4]), although it significantly increased subsequently (3.33%/4-weeks [95%CI: 3.28, 3.39]). In addition, weekly-to-monthly dosing significantly increased from 26.9% to 54.5% of patients (27.6 percentage points [95%CI: 26.9, 28.4]), although it significantly decreased subsequently (-1.19%/4-weeks [95%CI: -1.23, -1.15]). DISCUSSION: Despite large initial changes, we found a trend toward gradual return to more restrictive dosing schedules. OTPs need further support in leveraging new opportunities to improve methadone treatment and outcomes.
