An Implementation Perspective on Opioid Overdose Prevention

Reducing fatal opioid overdoses remains a major challenge for public health. Opioid overdose education and naloxone distribution (OEND) programs attempt to decrease opioid overdose by training substance users in recognizing its symptoms and in using naloxone. Naloxone is a short-acting opioid receptor antagonist effective in counteracting the respiratory depression that can lead to death during opioid overdose. While OEND programs are increasingly accepted as an effective public health strategy to reduce overdose fatalities, core elements of overdose prevention trainings and their impact on behavior still remain unexplored. The proposed project addresses these very questions by means of two studies conducted in New York City, a leader in the implementation of public health programming to prevent death from opioid overdose. Study 1 aims at evaluating the implementation of OEND programs in nine organizations involved in the care of opioid users. The complexity of implementation processes will be incorporated in their evaluations by considering multiple indicators of implementation and by measuring them from different perspectives (i.e., trainer, trainee, and observer ratings). The study introduces innovative methods both in the measurement of implementation outcomes (by realizing multi-informant measures) and data analysis (in terms of a multilevel approach). By analyzing implementation outcomes in relation to program outcomes, the results will allow identifying core components of the intervention and its implementation which have the largest effect on training outcomes in terms of substance users increased knowledge and ability to manage an overdose. Thereby, we provide a crucial knowledge-base for improving subsequent implementation processes to better adapt the program to practice conditions and enhancing program outcomes. Study 2 aims at testing hypothesized associations between different levels of training outcomes (i.e., learning, behavior and results). Establishing trainees post-training knowledge as a predictor of results (i.e., decreases in fatal overdoses) will facilitate systematic evaluations of the quality and impact of OEND programs in various settings, even if resources do not allow for long- term follow-up. Initial implementation of OEND programs in Austria is expected in autumn 2018 with a two- year pilot project in the province of Styria. Close cooperation of the applicant with the project team in Styria will help building capacity for successfully implementing OEND programs in Austria from the very beginning. During the return phase, the proposed project will focus on developing guidelines for OEND program policy and procedures and an implementation strategy for a comprehensive evaluation concept targeting Austrian OEND programs. The work is expected to initiate a process of accepting the relevance of implementation research for evidence-based practice in health services and to move one step closer to a systematic organization of implementation processes in Austrian public health.

This study conducted a comprehensive evaluation of Overdose Education and Naloxone Distribution (OEND) programs in New York City, focusing on the effectiveness of these programs in enhancing knowledge and attitudes towards opioid overdoses. The research involved 16 OEND training sessions with 75 participants, examining the relationship between implementation outcomes (such as fidelity and acceptability) and the success of the intervention in terms of knowledge and attitude change. The study's main findings include: Significant Improvement in Knowledge and Attitudes: Participants exhibited substantial increases in their understanding of opioid overdoses and improved attitudes towards managing such situations following the training. This change was measured using pre- and post-training assessments. Importance of Fidelity: The fidelity of training delivery, especially the adherence of trainers to the set protocols, was a critical factor in predicting the effectiveness of the training in improving knowledge about overdoses. Fidelity was assessed from three different perspectives: the trainees, the trainers, and an independent observer. Notably, the independent observer's perspective was particularly significant in predicting changes in overdose knowledge. Role of Training Duration: The length of the training sessions was positively correlated with the outcomes. Longer sessions were more effective in increasing knowledge and improving attitudes, suggesting that more comprehensive training can lead to better understanding and preparedness among participants. High Acceptability and Diverse Context: Both trainers and trainees rated the OEND program highly in terms of acceptability. This positive reception is crucial for the success and continuation of such public health initiatives. Additionally, the training sessions varied in duration, group size, and audience demographics. This diversity indicates that OEND programs are adaptable and can be effectively implemented across different settings and populations. Training Quality and Independent Assessment: The study highlights the need for high-quality training delivery in overdose prevention programs. The independent assessment of training fidelity emerged as a key factor in evaluating the effectiveness of these programs, suggesting that external evaluations can provide valuable insights into the training process and its outcomes. Overall, the study emphasizes the importance of OEND programs in addressing the opioid crisis. It provides evidence that well-implemented training programs, which adhere to quality protocols and are tailored to the needs of diverse groups, can significantly improve knowledge and attitudes regarding opioid overdose management. These findings are particularly relevant for public health strategies aimed at reducing opioid overdose fatalities and can inform future implementations and adaptations of OEND programs.
