Objective To evaluate the impact of state supported overdose education and nasal naloxone distribution (OEND) programs on rates of opioid related death from overdose and acute care utilization in Massachusetts. Design Interrupted time series analysis of opioid related overdose death and acute care utilization rates from 2002 to 2009 comparing community-year strata with high and low rates of OEND implementation to those with no implementation. Setting 19 Massachusetts communities (geographically distinct cities and towns) with at least five fatal opioid overdoses in each of the years 2004 to 2006. Participants OEND was implemented among opioid users at risk for overdose, social service agency staff, family, and friends of opioid users. Intervention OEND programs equipped people at risk for overdose and bystanders with nasal naloxone rescue kits and trained them how to prevent, recognize, and respond to an overdose by engaging emergency medical services, providing rescue breathing, and delivering naloxone. Main outcome measures Adjusted rate ratios for annual deaths related to opioid overdose and utilization of acute care hospitals. Results Among these communities, OEND programs trained 2912 potential bystanders who reported 327 rescues. Both community-year strata with 1-100 enrollments per 100 000 population (adjusted rate ratio 0.73, 95% confidence interval 0.57 to 0.91) and community-year strata with greater than 100 enrollments per 100 000 population (0.54, 0.39 to 0.76) had significantly reduced adjusted rate ratios compared with communities with no implementation. Differences in rates of acute care hospital utilization were not significant. Conclusions Opioid overdose death rates were reduced in communities where OEND was implemented. This study provides observational evidence that by training potential bystanders to prevent, recognize, and respond to opioid overdoses, OEND is an effective intervention.

Saved by the Nose: Bystander-Administered Intranasal Naloxone Hydrochloride for Opioid Overdose

Maya Doe-Simkins; Alexander Y. Walley; Andy Epstein; Peter Moyer

Administering naloxone hydrochloride (naloxone) during an opioid overdose reverses the overdose and can prevent death. Although typically delivered via intramuscular or intravenous injection, naloxone may be delivered via intranasal spray device. In August 2006, the Boston Public Health Commission passed a public health regulation that authorized an opioid overdose prevention program that included intranasal naloxone education and distribution of the spray to potential bystanders. Participants were taught by trained nonmedical needle exchange staff. After 15 months, the program provided training and intranasal naloxone to 385 participants who reported 74 successful overdose reversals. Problems with intranasal naloxone were uncommon. Overdose prevention education with distribution of intranasal naloxone is a feasible public health intervention to address opioid overdose.

BackgroundBuprenorphine is a safe, effective and underutilized treatment for opioid dependence that requires special credentialing, known as a waiver, to prescribe in the United States.ObjectiveTo describe buprenorphine clinical practices and barriers among office-based physicians.DesignCross-sectional survey.ParticipantsTwo hundred thirty-five office-based physicians waivered to prescribe buprenorphine in Massachusetts.MeasurementsQuestionnaires mailed to all waivered physicians in Massachusetts in October and November 2005 included questions on medical specialty, practice setting, clinical practices, and barriers to prescribing. Logistic regression analyses were used to identify factors associated with prescribing.ResultsPrescribers were 66% of respondents and prescribed to a median of ten patients. Clinical practices included mandatory counseling (79%), drug screening (82%), observed induction (57%), linkage to methadone maintenance (40%), and storing buprenorphine notes separate from other medical records (33%). Most non-prescribers (54%) reported they would prescribe if barriers were reduced. Being a primary care physician compared to a psychiatrist (AOR: 3.02; 95% CI: 1.48–6.18) and solo practice only compared to group practice (AOR: 3.01; 95% CI: 1.23–7.35) were associated with prescribing, while reporting low patient demand (AOR: 0.043, 95% CI: 0.009–0.21) and insufficient institutional support (AOR: 0.37; 95% CI: 0.15–0.89) were associated with not prescribing.ConclusionsCapacity for increased buprenorphine prescribing exists among physicians who have already obtained a waiver to prescribe. Increased efforts to link waivered physicians with opioid-dependent patients and initiatives to improve institutional support may mitigate barriers to buprenorphine treatment. Several guideline-driven practices have been widely adopted, such as adjunctive counseling and monitoring patients with drug screening.

Expanded Access to Naloxone Among Firefighters, Police Officers, and Emergency Medical Technicians in Massachusetts

Corey S. Davis; Sarah Ruiz; Patrick Glynn; Gerald Picariello; Alexander Y. Walley

Naloxone is a medication that reverses respiratory depression from opioid overdose if given in time. Paramedics routinely administer naloxone to opioid overdose victims in the prehospital setting, and many states are moving to increase access to the medication. Several jurisdictions have expanded naloxone administration authority to nonparamedic first responders, and others are considering that step. We report here on policy change in Massachusetts, where several communities have equipped emergency medical technicians, law enforcement officers, and firefighters with naloxone.

Prevention of Fatal Opioid Overdose

Leo Beletsky; Josiah D. Rich; Alexander Y. Walley

Opioid overdose is a burgeoning public health crisis, accounting for at least 16,000 deaths annually in the United States. Opioid overdose occurs across sex, ethnic, age, and geographic strata and involves both medical and nonmedical opioid use. To date, federal government response has focused primarily on monitoring and securing the drug supply. This Viewpoint suggests various steps necessary to support a more comprehensive approach.

Opioid overdose prevention with intranasal naloxone among people who take methadone

Alexander Y. Walley; Maya Doe-Simkins; Emily Quinn; Courtney Pierce; Ziming Xuan; Al Ozonoff

Overdose education and naloxone distribution (OEND) is an intervention that addresses overdose, but has not been studied among people who take methadone, a drug involved in increasing numbers of overdoses. This study describes the implementation of OEND among people taking methadone in the previous 30 days in various settings in Massachusetts. From 2008 to 2010, 1553 participants received OEND who had taken methadone in the past 30 days. Settings included inpatient detoxification (47%), HIV prevention programs (25%), methadone maintenance treatment programs (MMTP) (17%), and other settings (11%). Previous overdose, recent inpatient detoxification and incarceration, and polysubstance use were overdose risks factors common among all groups. Participants reported 92 overdose rescues. OEND programs are public health interventions that address overdose risk among people who take methadone and their social networks. OEND programs can be implemented in MMTPs, detoxification programs, and HIV prevention programs.

BACKGROUND As physicians have increased opioid prescribing, overdose deaths from pharmaceutical opioids have substantially increased in the United States. Naloxone hydrochloride (naloxone), an opioid antagonist, is the standard of care for treatment of opioid induced respiratory depression. Since 1996, community-based programs have offered overdose prevention education and distributed naloxone for bystander administration to people who use opioids, particularly heroin. There is growing interest in translating overdose education and naloxone distribution (OEND) into conventional medical settings for patients who are prescribed pharmaceutical opioids. For this review, we summarized and classified existing publications on overdose education and naloxone distribution to identify evidence of effectiveness and opportunities for translation into conventional medical settings. METHODS For this review, we searched English language PubMed for articles on naloxone based on primary data collection from humans, including feasibility studies, program evaluations, surveys, qualitative studies, and studies comparing the effectiveness of different routes of naloxone administration. We also included cost-effectiveness studies. RESULTS We identified 41 articles that represented 5 categories: evaluations of OEND programs, effects of OEND programs on experiences and attitudes of participants, willingness of medical providers to prescribe naloxone, comparisons of different routes of naloxone administration, and the cost-effectiveness of naloxone. CONCLUSIONS Existing research suggests that people who are at risk for overdose and other bystanders are willing and able to be trained to prevent overdoses and administer naloxone. Counseling patients about the risks of opioid overdose and prescribing naloxone is an emerging clinical practice that may reduce fatalities from overdose while enhancing the safe prescribing of opioids.

Increasing rates of maternal opioid use during pregnancy and neonatal withdrawal, termed neonatal abstinence syndrome (NAS), are public health concerns. Prenatal buprenorphine maintenance treatment (BMT) versus methadone maintenance treatment (MMT) may improve neonatal outcomes, but associations vary. To summarize evidence, we used a random-effects meta-analysis model and estimated summary measures of BMT versus MMT on several outcomes. Sensitivity analyses evaluated confounding, publication bias, and heterogeneity. Subjects were 515 neonates whose mothers received BMT and 855 neonates whose mothers received MMT and who were born from 1996 to 2012 and who were included in 12 studies. The unadjusted NAS treatment risk was lower (risk ratio=0.90, 95% confidence interval (CI): 0.81, 0.98) and mean length of hospital stay shorter (-7.23 days, 95% CI: -10.64, -3.83) in BMT-exposed versus MMT-exposed neonates. In treated neonates, NAS treatment duration was shorter (-8.46 days, 95% CI: -14.48, -2.44) and morphine dose lower (-3.60 mg, 95% CI: -7.26, 0.07) in those exposed to BMT. BMT-exposed neonates had higher mean gestational age and greater weight, length, and head circumference at birth. Fewer women treated with BMT used illicit opioids near delivery (risk ratio=0.44, 95% CI: 0.28, 0.70). Simulations suggested that confounding by indication could account for some of the observed differences. Prenatal BMT versus MMT may improve neonatal outcomes, but bias may contribute to this protective association. Further evidence is needed to guide treatment choices.

BACKGROUND Studies on the mechanisms of the association between illicit drug use and HIV/STI provide important insight into why there are disproportionate rates of HIV/STI among heterosexual African American men; far less work has been conducted to examine the associations between binge alcohol use and HIV/STI risks in this population. OBJECTIVE To assess whether binge alcohol use is associated with risky sexual behaviors and recent HIV/STI diagnosis among heterosexual African American men reporting multiple sex partners in the past year. METHODS Participants (n=672) were heterosexually active African American men age 18-65 years recruited from urban health centers and clinics in Boston, MA, and who participated in a health survey. Logistic regression analyses were used to assess associations between past 30 day binge drinking and the following outcome variables: unprotected sex, six or more sex partners in the past year, sex trade involvement, and past 6 month HIV/STI diagnosis. Analyses were adjusted to control demographics, incarceration history, illicit drug use, and injection drug use. RESULTS Significant associations were observed between binge alcohol use and unprotected vaginal sex with non-main female partners (AOR=1.7, 95% CI=1.2-2.3), unprotected anal sex with non-main female partners (AOR=2.3, 95% CI=1.4-4.0), sex trade involvement (AOR=2.1, 95% CI=1.3-3.5), and recent HIV/STI diagnosis (AOR=1.9; 95% CI=1.05-3.6). CONCLUSION Heterosexual African American men engaging in binge alcohol use may be at increased risk for HIV/STI; findings support the need for integrating alcohol risk reduction into HIV prevention programs targeting this population.

Orienting Patients to Greater Opioid Safety: Models of Community Pharmacy-Based Naloxone

Traci C. Green; Emily F. Dauria; Jeffrey P. Bratberg; Corey S. Davis; Alexander Y. Walley

The leading cause of adult injury death in the USA is drug overdose, the majority of which involves prescription opioid medications. Outside of the USA, deaths by drug overdose are also on the rise, and overdose is a leading cause of death for drug users. Reducing overdose risk while maintaining access to prescription opioids when medically indicated requires careful consideration of how opioids are prescribed and dispensed, how patients use them, how they interact with other medications, and how they are safely stored. Pharmacists, highly trained professionals expert at detecting and managing medication errors and drug-drug interactions, safe dispensing, and patient counseling, are an under-utilized asset in addressing overdose in the US and globally. Pharmacies provide a high-yield setting where patient and caregiver customers can access naloxone—an opioid antagonist that reverses opioid overdose—and overdose prevention counseling. This case study briefly describes and provides two US state-specific examples of innovative policy models of pharmacy-based naloxone, implemented to reduce overdose events and improve opioid safety: Collaborative Pharmacy Practice Agreements and Pharmacy Standing Orders.
