What is the purpose of this trial?

This trial explores a new strategy to improve naloxone distribution through syringe service programs (SSPs). Researchers aim to determine if a special coaching method, SAIA-N (Systems Analysis and Improvement Approach for Naloxone), can help these programs distribute more naloxone compared to their usual methods and assess its cost-effectiveness. SSPs in California that already provide naloxone qualify for this study, provided they have not participated in the SAIA-N pilot before. As an unphased trial, this study presents a unique opportunity to contribute to innovative strategies that could enhance naloxone distribution and potentially save lives.

Will I have to stop taking my current medications?

The trial information does not specify whether participants need to stop taking their current medications.

What prior data suggests that the Systems Analysis and Improvement Approach for Naloxone (SAIA-N) is safe for improving naloxone distribution?

Research has shown that naloxone is generally safe for use. Widely used to reverse opioid overdoses, naloxone is well-tolerated. The Systems Analysis and Improvement Approach for Naloxone (SAIA-N) is not a drug but a method to enhance naloxone distribution. Therefore, SAIA-N does not carry the safety risks associated with new drugs. Instead, it aids organizations in distributing naloxone more effectively. No reports have indicated problems related to SAIA-N. Naloxone itself maintains a strong safety record. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about the Improved Naloxone Access trial because it explores how to enhance naloxone distribution within syringe service programs (SSPs), beyond just providing naloxone itself. This trial is testing the Systems Analysis and Improvement Approach for Naloxone (SAIA-N), which is an innovative method that involves assigning coaches to help SSP staff identify and overcome barriers to effective naloxone distribution. Unlike the usual approach, which doesn’t offer additional support, SAIA-N aims to optimize existing naloxone distribution efforts by engaging staff in continuous improvement cycles. This method could potentially lead to more efficient and widespread access to naloxone, a life-saving medication for opioid overdoses.

What evidence suggests that this trial's strategies could be effective for improving naloxone distribution?

Research shows that the Systems Analysis and Improvement Approach for Naloxone (SAIA-N), which participants in this trial may experience, might help syringe service programs distribute more naloxone. This method employs a trained coach to assist these programs in identifying and resolving barriers to naloxone distribution, a life-saving drug during opioid overdoses. Similar strategies have proven effective in the past for improving naloxone distribution. The aim is to increase naloxone availability, especially in high-need areas. While specific data on SAIA-N is still being collected, early indications suggest it might outperform usual methods, which are also under study in this trial. ^{1 2 5 6 7}

Are You a Good Fit for This Trial?

This trial is for syringe service programs (SSPs) in California that are authorized by CDPH and have recently distributed naloxone.

• Systems Analysis and Improvement Approach for Naloxone (SAIA-N)
• Usual intervention

Trial Overview

The study tests a new strategy called SAIA-N against the usual way SSPs give out naloxone. SAIA-N involves regular meetings with a coach to help optimize distribution over 12 months. The effectiveness will be measured by the number of doses and people reached, especially among BIPOC communities.

How Is the Trial Designed?

Group I: SAIA-Naloxone Experimental Treatment 1 Intervention

SAIA-Naloxone is an intervention that facilitates an organizational SSP level analysis of naloxone delivery by assigning a trained SAIA-Naloxone coach to apply tools and techniques and engage staff to define barriers, identify solutions, and evaluate their success in cycles until achieving desired change regarding naloxone distribution. Coaches will meet with SSPs twice per month for the first 3 months and once per month for the remaining 9 months during the 12-month intervention period.

Group II: Implementation as Usual Experimental Treatment 1 Intervention

SSPs randomized to the IAU arm will not receive support to improve naloxone distribution. SSPs in California have already adopted naloxone distribution. The investigators are therefore testing the ability of SAIA-Naloxone to optimize naloxone distribution within SSPs. Accordingly, IAU is characterized by the absence of SAIA-Naloxone with the goal of comparing whether SAIA-Naloxone improves SSPs' Naloxone distribution.

In a study involving 42 healthy participants, the naloxone auto-injector (NAI) was significantly more effective than the intranasal delivery system (NXN) for administering naloxone during a simulated opioid overdose, with 90.5% success for NAI compared to 0% for NXN before training.

After training, 100% of participants successfully used NAI, while only 57.1% could use NXN, highlighting that NAI is easier to use and requires less training for effective administration.

A study involving 122 HIV clinicians showed that on-site peer-to-peer training significantly increased their likelihood to prescribe naloxone, with an odds ratio of 4.1, indicating a strong positive change in attitudes towards naloxone prescribing.

The intervention led to a notable increase in the number of clinicians prescribing naloxone across 18 out of 22 sites, with a 2.9 times higher incidence rate of naloxone prescriptions post-intervention, although the overall percentage of HIV patients receiving naloxone only modestly increased from 0.97% to 1.6%.

In a study of 123 patients with rattlesnake envenomations, those treated with the equine-derived antivenom F (ab')2 AV were less likely to develop late coagulopathy compared to those treated with the ovine-derived Fab AV, indicating a potential safety advantage for F (ab')2 AV.

Patients receiving F (ab')2 AV were also more likely to require additional doses of antivenom, suggesting that while both treatments are effective, the dosing strategy may differ between the two antivenoms.
