Background: Methamphetamine overdose can cause severe psychological and physical health issues including psychosis, heart attack, and death. People who use methamphetamine (PWUM) who experience methamphetamine overdose symptoms (MOS) are advised to seek emergency healthcare; however, factors related to seeking care are not well characterized., Methods: This study used data from the 2021 Washington State Syringe Services Program (SSP) Health Survey, a cross-sectional survey administered to participants at 21 SSPs in Washington ( N  = 955). Participants answered questions related to substance use including emergency department/room (ER) utilization for methamphetamine use and whether they experienced psychological and physical MOS. Using Poisson regression, we assessed the association between ER utilization for methamphetamine use, non-fatal opioid overdose, and other key covariates among PWUM who experienced MOS., Results: Methamphetamine use in the last three months was reported by 86% of participants. Among PWUM, 31% reported psychological MOS, 19% reported physical MOS, and 37% reported ≥1 MOS in the prior three months. Non-fatal opioid overdose (adjusted prevalence ratio [APR] = 2.04, 95% CI = 1.38-3.03), main drug of goofball (heroin and methamphetamine combined) (APR = 1.98, 95% CI = 1.34-2.92) and recent blood infection/sepsis (APR = 2.07, 95% CI = 1.24-3.46) were associated with ER utilization for MOS., Conclusion: Among people who use SSPs in Washington State, methamphetamine use remains high, and MOS are common. Recent non-fatal opioid overdose was positively associated with ER utilization for methamphetamine use among PWUM who experienced MOS. Patients in the ER for MOS should be screened for opioid use disorder and linked with harm reduction supplies like naloxone and medications for opioid use disorder.

Background: Syringe service programs (SSPs) provide tools to people who inject drugs (PWID) to prevent overdose, reduce the risk of HIV and HCV infection, and reduce injection frequency. While effective, previous research suggests that SSPs may not adequately reach some marginalized or particularly vulnerable subpopulations of PWID., Methods: To identify disparities in SSP use, data from two cross-sectional surveys conducted in King County, Washington were compared: a survey of SSP clients and a community survey of PWID in King County. It was hypothesized that Black PWID, women, and gender minorities would be underrepresented in the SSP survey relative to the general population of PWID., Results: SSP clients identified as White at a significantly higher rate than the community sample of PWID (p = 0.030). Black (p < 0.001), American Indian/Alaska Native (p < 0.001), Latinx/Hispanic (p = 0.009), and Native Hawaiian/ Pacific Islander PWID (p = 0.034) were underrepresented in the SSP client survey. The gender of SSP clients was similar to the distribution seen in the community sample of PWID (p = 0.483)., Conclusions: Black PWID are underrepresented in Seattle-area SSPs, consistent with studies in other large US cities. Both nationally and in Seattle, overdose deaths have been increasing among Black PWID, and harm reduction strategies are vital to reversing this trend. SSPs should explore and test ways to be more accessible to minority populations., (© 2023. BioMed Central Ltd., part of Springer Nature.)

Background: Opioid overdose is a major and increasing cause of injury and death. There is an urgent need for interventions to reduce overdose events among high-risk persons., Methods: Adults at elevated risk for opioid overdose involving heroin or pharmaceutical opioids who had been cared for in an emergency department (ED) were randomised to overdose education combined with a brief behavioural intervention and take-home naloxone or usual care. Outcomes included: (1) time to first opioid overdose-related event resulting in medical attention or death using competing risks survival analysis; and (2) ED visit and hospitalisation rates, using negative binomial regression and adjusting for time at risk., Results: During the follow-up period, 24% of the 241 participants had at least one overdose event, 85% had one or more ED visits and 55% had at least one hospitalisation, with no significant differences between intervention and comparison groups. The instantaneous risk of an overdose event was not significantly lower for the intervention group (sub-HR: 0.83; 95% CI 0.49 to 1.40)., Discussion: These null findings may be due in part to the severity of the population in terms of housing insecurity (70% impermanently housed), drug use, unemployment and acute healthcare issues. Given the high overdose and healthcare utilisation rates, more intensive interventions, such as direct referral and provision of housing and opioid agonist treatment medications, may be necessary to have a substantial impact on opioid overdoses for this high-acuity population in acute care settings., Trial Registration Number: NCT0178830; Results., Competing Interests: Competing interests: POC has previously directed National Institutes of Health-funded trials that have received donated study medications from Alkermes (2014–2015) and Gilead (2015–2017)., (© Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2019.

This educational review presents an overview of opioid use disorder, misuse and overdose among adolescents, and the clinical implications for anesthesiologists. It provides definitions, discusses the epidemiology worldwide, (focusing on North America), and emphasizes the clinical implications of patients with chronic opioid exposure, including perioperative pain management, as well as opioid overdose and prolonged use of opioids after acute exposure. In the USA, opioid use disorder and negative outcomes related to opioids rose dramatically from 1999-2010; concomitantly heroin use and fatal overdoses have increased as heroin use is associated with the disordered use of licit opioids. Among adolescents and young adults, opioid use disorder is significant, with continued increases in disordered use specifically among young adults. Acute opioid intoxication may have multiple medical implications in addition to respiratory depression, and children are susceptible to acute intoxication via accidental ingestion of prescription opioids. Novel opioid formulations, such as acetyl fentanyl, with unpredictable pharmacology may also be present in acute intoxication. Chronically, opioid use presents challenges for safe and adequate pain management, in the presence of opioid-induced hyperalgesia and differential tolerance as well as mental health issues including depression and anxiety. Predictors of prolonged opioid use in adolescents and adults after surgery is an area of ongoing research. Young patients encountered by pediatric anesthesiologists may be involved in diversion and disordered use of opioids. Increased awareness among anesthesiologists is important, as perioperative discussions often provide an opportunity to detect at risk patients., (© 2017 John Wiley & Sons Ltd.)

Background: Emergency Medical Services (EMS) data may provide insight into opioid overdose incidence, clinical characteristics, and medical response. This analysis describes patient characteristics, clinical features, and EMS response to opioid overdoses, comparing heroin and pharmaceutical opioid (PO) overdoses, using a structured opioid overdose case criteria definition., Methods: A case series study was conducted. EMS medical staff screened cases for possible overdoses and study staff categorized the likelihood of opioid overdose. Medical form data were abstracted. Patient characteristics, clinical presentation, and medical response to heroin and PO-involved overdoses were compared with bi-variate test statistics., Results: We identified 229 definite or probable opioid overdose cases over six months: heroin in 98 (43%) cases (10 also involved PO), PO without heroin in 85 (37%) cases, and 46 (20%) that could not be categorized and were excluded from analyses. Heroin overdose patients were younger than PO (median age 33 v 41 (p<0.05)), more often male (80% v 61% (p=<0.01)), intubated less (8% v 22%, p<0.01) and more likely to be administered naloxone (72% v 51%, p<0.01). No significant differences were found between heroin and PO overdoses for initial respiratory rate, Glasgow Coma Scale score, or co-ingestants, but heroin users were more likely to have miotic pupils (p<0.01)., Conclusions: While heroin and PO events presented similarly, heroin-involved cases were more likely to receive naloxone and less likely to be intubated. Standardized case definitions and data documentation could aid opioid overdose surveillance as well as provide data for measuring the impact of professional and lay interventions., (Copyright © 2017 Elsevier B.V.

Background: Fatal opioid overdose is a significant public health concern in the United States. One approach to reducing fatalities is expanding overdose response education to broader audiences. This study examined responses to a web-based overdose education tool., Methods: The results of 422 anonymous surveys submitted on www.stopoverdose.org were analyzed for participant demographics, knowledge of opioid overdose recognition and response, and knowledge of Washington's Good Samaritan overdose law. Characteristics, knowledge, and planned behavior of respondents with professional versus personal interest in overdose education were compared., Results: Most respondents were age 35 or older (57%) and female (65%). The mean score on the knowledge quiz for overdose recognition and response items was 16.2 out of 18, and 1.5 out of 2 possible points for items concerning the law. Respondents indicating professional interest were significantly more likely to be 35 or older (p = .001) and to have received prior overdose education (p < .001), but less likely to know someone at risk for opioid overdose (p < .001) or report planning to obtain take-home naloxone (p < .001). No significant differences were found in overdose knowledge scores between groups., Conclusions: Online training may be effective among individuals with professional and personal interest in overdose, as general knowledge scores of overdose response were high among both groups. Lower scores reflecting knowledge of the law suggest that the web-based training may not have adequately presented this information. Overall, results suggest that a web-based platform may be a promising approach to basic overdose education.

An epidemic of morbidity and mortality has swept across the United States related to the use of prescription opioids for chronic noncancer pain. More than 100,000 people have died from unintentional overdose, making this one of the worst manmade epidemics in history. Much of health care delivery in the United States is regulated at the state level; therefore, both the cause and much of the cure for the opioid epidemic will come from state action. We detail the strong collaborations across executive health care agencies, and between those public agencies and practicing leaders in the pain field that have led to a substantial reversal of the epidemic in Washington State.

Opioid overdoses are an important public health concern. Concerns about police involvement at overdose events may decrease calls to 911 for emergency medical care thereby increasing the chances than an overdose becomes fatal. To address this concern, Washington State passed a law that provides immunity from drug possession charges and facilitates the availability of take-home-naloxone (the opioid overdose antidote) to bystanders in 2010. To examine the knowledge and opinions regarding opioid overdoses and this new law, police (n = 251) and paramedics (n = 28) in Seattle, WA were surveyed. The majority of police (64 %) and paramedics (89 %) had been at an opioid overdose in the prior year. Few officers (16 %) or paramedics (7 %) were aware of the new law. While arrests at overdose scenes were rare, drugs or paraphernalia were confiscated at 25 % of the most recent overdoses police responded to. Three quarters of officers felt it was important they were at the scene of an overdose to protect medical personnel, and a minority, 34 %, indicated it was important they were present for the purpose of enforcing laws. Police opinions about the immunity and naloxone provisions of the law were split, and we present a summary of the reasons for their opinions. The results of this survey were utilized in public health efforts by the police department which developed a roll call training video shown to all patrol officers. Knowledge of the law was low, and opinions of it were mixed; however, police were concerned about the issue of opioid overdose and willing to implement agency-wide training.

Background: Long-term opioid therapy for chronic noncancer pain is becoming increasingly common in community practice. Concomitant with this change in practice, rates of fatal opioid overdose have increased. The extent to which overdose risks are elevated among patients receiving medically prescribed long-term opioid therapy is unknown., Objective: To estimate rates of opioid overdose and their association with an average prescribed daily opioid dose among patients receiving medically prescribed, long-term opioid therapy., Design: Cox proportional hazards models were used to estimate overdose risk as a function of average daily opioid dose (morphine equivalents) received at the time of overdose., Setting: HMO., Patients: 9940 persons who received 3 or more opioid prescriptions within 90 days for chronic noncancer pain between 1997 and 2005., Measurements: Average daily opioid dose over the previous 90 days from automated pharmacy data. Primary outcomes--nonfatal and fatal overdoses--were identified through diagnostic codes from inpatient and outpatient care and death certificates and were confirmed by medical record review., Results: 51 opioid-related overdoses were identified, including 6 deaths. Compared with patients receiving 1 to 20 mg/d of opioids (0.2% annual overdose rate), patients receiving 50 to 99 mg/d had a 3.7-fold increase in overdose risk (95% CI, 1.5 to 9.5) and a 0.7% annual overdose rate. Patients receiving 100 mg/d or more had an 8.9-fold increase in overdose risk (CI, 4.0 to 19.7) and a 1.8% annual overdose rate., Limitations: Increased overdose risk among patients receiving higher dose regimens may be due to confounding by patient differences and by use of opioids in ways not intended by prescribing physicians. The small number of overdoses in the study cohort is also a limitation., Conclusion: Patients receiving higher doses of prescribed opioids are at increased risk for overdose, which underscores the need for close supervision of these patients., Primary Funding Source: National Institute of Drug Abuse.
