Overdose Risk Management and Naloxone
Overdose Risk Management and Compensation in the Era of Naloxone

Detailed Description
Drug overdose (OD) deaths in the United States nearly tripled between 1999 and 2014. During 2015 more than 50,000 people died from overdose nationwide, and almost two thirds (63.1%) involved opioids.1 In response, the number of opioid OD prevention programs offering naloxone has ballooned.2 Many states have sought to expand access through provision of the medication to EMT and police first-responders, over-the-counter availability at pharmacies, and emergency legislation providing for lay prescribing, largely within the context of opioid OD prevention programs serving people who use heroin or diverted prescription opioids (henceforth, people who use illicit opioids; PWUIO). As naloxone has become more commonplace, however, OD rates have continued to rise, and critical viewpoints about the failure of OD reversal efforts to deter subsequent high-risk behavior have begun to emerge from police,3 firefighers,4 EMS personnel,5 and news media,6-8 especially following the recent loss of pop-artist, Prince, to an opioid OD only days after being administered naloxone in an Illinois hospital.9 This study is responsive to a recent NIDA and FDA mandate for foundational naloxone research among active users of illicit opioids.10 Specifically, it assesses two main concerns at the heart of current policymaking related to opioid OD and naloxone. 1) Disparities in access to naloxone and obstacles to a willingness to be trained as a naloxone-carrying OD responder: Despite the critically important role PWUIO can play as OD responders,11-15 questions remain about differential awareness of and access to naloxone and OD response training among PWUIO. Even in NYC where city and state departments of health have led concerted and well-funded efforts to saturate the city with naloxone and OD reversal training, considerable limitations in coverage and training uptake still exist.16 Findings from our ongoing study of opioid OD risks among military veterans in NYC indicate that many PWUIO are still naloxone-naïve and, even after learning about its lifesaving utility, still decline no-cost naloxone and OD response training. 2) The poorly understood impacts of possessing naloxone, using naloxone on someone else, or having it used on oneself on PWUIO's subsequent OD rates and risk behaviors: An increasing number of studies seek to track the uses to which naloxone kits are put, but the broader behavioral impacts of exposure to naloxone on actual opioid-related risk behaviors have seen almost no empirical investigation since 2003 when a study of street-recruited PWUIO in San Francisco reported that 35% indicated that they intended to use more heroin than usual after receiving naloxone.17 Building on our current studies of naloxone use and related attitudes among opioid-using military veterans and other drug users we propose to recruit 600 adult-age (18+) people who use illicit opioids (i.e., heroin and/or diverted pharmaceutical opioids) in New York City using Respondent Driven Sampling. At enrollment, participants will complete a detailed survey instrument establishing histories of substance use, naloxone exposure, and other potential barriers to the uptake of naloxone training. Because extant research establishes a clear public health and ethical imperative to provide PWUIO with naloxone, we will also offer all participants training to become naloxone-equipped OD responders at enrollment. We will follow the sample for two years using a mixed-methods approach involving text-message-based exposure tracking, monthly surveys using a state-of-the-art online data collection portal, and a qualitative subsample to ensure that naloxone exposures and changes in OD risk behavior are carefully tracked and contextualized by ethnographic data about the psychosocial and sociocultural mechanisms underlying participant experiences.
Aim A - Describe factors associated with: 1) lifetime history of access to and use of naloxone and 2) uptake of no-cost naloxone and OD response training. We will test the following hypotheses:
HypA1 - Naloxone knowledge and exposure history will vary at enrollment, potentially revealing disparities based on background factors (e.g., SES, ethnicity, age, neighborhood) and individual level factors (e.g., mental health diagnoses, opioid use disorder severity, duration of opioid use) HypA2 - Interest in OD response training and naloxone at baseline will vary by background and individual-level factors.
Aim B - Describe longitudinal relationships between naloxone exposure (access to and use of naloxone) and overdose risk behaviors. We will test the following hypothesis:
HypB1 - Naloxone access and use exposures will have measurable impacts on opioid OD-related risk behaviors over time, potentially varying in degree and direction across subgroups of PWUIO.
Aim C (Qualitative) - Explore barriers to naloxone uptake and any identified secondary impacts (e.g., compensatory risk taking, positive change after a naloxone exposure such as risk reduction or treatment-seeking) in terms of opioid users' own experiences and perceptions.
By employing a longitudinal and mixed-methods design capable of detecting naloxone exposure impacts and also illuminating the various mechanisms that may undergird them in participants' own terms, this project holds serious policy and direct service implications for the refinement of naloxone training programs and OD risk interventions that target PWUIO. This research also holds the potential to identify varying naloxone impacts among PWUIO of different social and behavioral groups-such as people who inject drugs (PWID) vs. prescription opioid misusers, older vs. younger (or shorter- vs. longer-term) PWUIO, and male vs. female users-and can inform future efforts to tailor prevention and education to these distinct subpopulations.

People who use illicit opioids
The study will recruit an adult-age (18+) sample of 600 people who use illicit opioids (either heroin or prescription opioid analgesics without a doctor's prescription) in New York City using Respondent Driven Sampling.
|
At enrollment, participants will complete a detailed survey instrument establishing histories of substance use, naloxone exposure, and other potential barriers to the uptake of naloxone training.
Because extant research establishes a clear public health and ethical imperative to provide PWUIO with naloxone, we will also offer all participants training to become naloxone-equipped OD responders at enrollment.
We will follow the sample for two years using a mixed-methods approach involving text-message-based exposure tracking, monthly surveys using a state-of-the-art online data collection portal, and a qualitative subsample to ensure that naloxone exposures and changes in OD risk behavior are carefully tracked and contextualized by ethnographic data about the psychosocial and sociocultural mechanisms underlying participant experiences.
