Evaluating the Efficiency and Productivity of Opioid Substitution Treatment Units in Greece: A DEA-Malmquist Analysis

This dip in efficiency likely reflects the impact of emerging drug trends, particularly stimulants and synthetic opioids, which lack standardized treatment protocols. These findings highlight the urgent need for new treatment options to address evolving addiction trends. The study also underscored the need for improved data collection and monitoring to optimize resource allocation and enhance operational efficiency in OST units. Strengthening evidence-based policies and expanding access with low-threshold treatment services could improve patient outcomes and the overall effectiveness of OST programs.
