Naloxone, an injectable opiate antagonist, can immediately reverse an opiate overdose and prevent overdose death. We sought to determine injection drug users' (IDUs) attitudes about being prescribed take-home naloxone. During November 1999 to February 2000, we surveyed 82 street-recruited IDUs from the San Francisco Bay Area of California who had experienced one or more heroin overdose events. ⋯ If provided naloxone, 35% predicted that they might feel comfortable using greater amounts of heroin, 62% might be less inclined to call 911 for an overdose, 30% might leave an overdose victim after naloxone resuscitation, and 46% might not be able to dissuade the victim from using heroin again to alleviate withdrawal symptoms induced by naloxone. Prescribing take-home naloxone to IDUs with training in its use and in resuscitation techniques may represent a life-saving, peer-based adjunct to accessing emergency services. Nevertheless, strategies for overcoming potential risks associated with the use of take-home naloxone would need to be emphasized in an overdose management training program.

Comparative Study
Clinical evaluation of the Emergency Medical Services (EMS) ambulance dispatch-based syndromic surveillance system, New York City.
Since 1998, the New York City Department of Health has used New York City Emergency Medical Services (EMS) ambulance dispatch data to monitor for a communitywide rise in influenzalike illness (ILI) as an early detection system for bioterrorism. A clinical validation study was conducted during peak influenza season at six New York City emergency departments (EDs) to compare patients with ILI brought in by ambulance with other patients to examine potential biases associated with ambulance dispatch-based surveillance. We also examined the utility of 4 EMS call types (selected from 52) for case detection of ILI. ⋯ The selected call types had a sensitivity of 58% for clinical ILI, and a predictive value positive of 22%. Individuals with symptoms consistent with the prodrome of inhalational anthrax were likely to utilize the EMS system and usually did so early in the course of illness. While EMS-based surveillance is more sensitive for severe illness and for illness affecting older individuals, there is not necessarily a loss of timeliness associated with EMS-based (versus ED-based) surveillance.

Preliminary research suggests that naloxone (Narcan), a short-acting opiate antagonist, could be provided by prescription or distribution to heroin users to reduce the likelihood of fatality from overdose. We conducted a random postal survey of 1100 prescription-authorized health care providers in New York City to determine willingness to prescribe naloxone to patients at risk of an opiate overdose. Among 363 nurse practitioners, physicians, and physician assistants responding, 33.4% would consider prescribing naloxone, and 29.4% were unsure. This preliminary study suggests that a substantial number of New York City health care providers would prescribe naloxone for opiate overdose prevention.

The Electronic Surveillance System for the Early Notification of Community-Based Epidemics, or ESSENCE II, uses syndromic and nontraditional health information to provide very early warning of abnormal health conditions in the National Capital Area (NCA). ESSENCE II is being developed for the Department of Defense Global Emerging Infections System and is the only known system to combine both military and civilian health care information for daily outbreak surveillance. The National Capital Area has a complicated, multijurisdictional structure that makes data sharing and integrated regional surveillance challenging. ⋯ Outbreak detection methods currently include temporal and spatial variations of odds ratios, autoregressive modeling, cumulative summation, matched filter, and scan statistics. Integration of nonuniform data is needed to increase sensitivity and thus enable the earliest notification possible. The performance of various detection techniques was compared using results obtained from the ESSENCE II system.

Drug overdose is a major cause of premature death and morbidity among heroin users. This article examines recent research into heroin overdose to inform interventions that will reduce the rate of overdose death. ⋯ Responses by heroin users at overdoses are also examined. Potential interventions to reduce the rate of overdose and overdose-related morbidity are examined in light of the emerging data in this field.
