Characteristics of a Multistate Outbreak of Lung Injury Associated with E-cigarette Use, or Vaping - United States, 2019.

Electronic cigarettes (e-cigarettes), also called vapes, e-hookas, vape pens, tank systems, mods, and electronic nicotine delivery systems (ENDS), are electronic devices that produce an aerosol by heating a liquid typically containing nicotine, flavorings, and other additives; users inhale this aerosol into their lungs (1). E-cigarettes also can be used to deliver tetrahydrocannabinol (THC), the principal psychoactive component of cannabis (1). Use of e-cigarettes is commonly called vaping. Lung injury associated with e-cigarette use, or vaping, has recently been reported in most states (2-4). CDC, the Food and Drug Administration (FDA), state and local health departments, and others are investigating this outbreak. This report provides data on patterns of the outbreak and characteristics of patients, including sex, age, and selected substances used in e-cigarette, or vaping, products reported to CDC as part of this ongoing multistate investigation. As of September 24, 2019, 46 state health departments and one territorial health department had reported 805 patients with cases of lung injury associated with use of e-cigarette, or vaping, products to CDC. Sixty-nine percent of patients were males, and the median age was 23 years (range = 13-72 years). To date, 12 deaths have been confirmed in 10 states. Among 514 patients with information on substances used in e-cigarettes, or vaping products, in the 30 days preceding symptom onset, 76.9% reported using THC-containing products, and 56.8% reported using nicotine-containing products; 36.0% reported exclusive use of THC-containing products, and 16.0% reported exclusive use of nicotine-containing products. The specific chemical exposure(s) causing the outbreak is currently unknown. While this investigation is ongoing, CDC recommends that persons consider refraining from using e-cigarette, or vaping, products, particularly those containing THC. CDC will continue to work in collaboration with FDA and state and local partners to investigate cases and advise and alert the public on the investigation as additional information becomes available.

The influence of living along the U.S.-Mexico border on unintentional drug overdose death, New Mexico (USA), 2005-2009.

BACKGROUND: The objective of this study was to characterize unintentional drug overdose death patterns among Hispanic ethnicity/sex strata by residence in New Mexico counties that border Mexico and non-border counties. METHODS: We analyzed medical examiner data for all unintentional drug overdose death in New Mexico during 2005-2009. Logistic and Poisson regression was used to examine the relationship of unintentional drug overdose death with border residence and demographics. Risk of overdose death was examined by the interactions of ethnicity, sex and border residence. RESULTS: During 2005-2009, the statewide drug overdose death rate was 17.6 per 100,000 (n=1812). Border decedents were more likely to have died from overdose of prescription opioids other than methadone (Schedule II, Adjusted Odds Ratio (aOR)=1.98; Schedule III/IV, aOR=1.56) but less likely to have died from heroin overdose (aOR=0.35), compared to non-border decedents. In population-based analyses, people living in border counties had lowest rates of overall overdose death and from illicit drugs, particularly heroin and cocaine. Hispanic males (adjusted incidence rate ratio [aRR]=2.41), Hispanic females (aRR=1.77) and non-Hispanic males (aRR=1.37) from non-border counties had higher risk of drug overdose death than their counterparts from border counties. Border residence had no effect on risk of drug overdose death among non-Hispanic females. CONCLUSIONS: Residents in border counties incurred a protective effect for drug overdose death, most pronounced among Hispanics. There is a component of overdose death risk for which border residence is a proxy, likely an array of cultural and healthcare-related factors.

A history of being prescribed controlled substances and risk of drug overdose death.

OBJECTIVE: The abuse of prescription drugs has increased dramatically since 1990. Persons who overdose on such drugs frequently consume large doses and visit multiple providers. The risk of fatal overdose for different patterns of use of opioid analgesics and sedative/hypnotics has not been fully quantified. DESIGN: Matched case-control study. Cases were 300 persons who died of unintentional drug overdoses in New Mexico during 2006-2008, and controls were 5,993 patients identified through the state prescription monitoring program with matching 6-month exposure periods. OUTCOME MEASURES: Death from drug overdose or death from opioid overdose. Exposures were demographic variables and characteristics of prescription history. Crude and adjusted odds ratios (AOR) were calculated. RESULTS: Increased risk was associated with male sex (AOR 2.4, 95% confidence interval [CI] 1.8-3.1), one or more sedative/hypnotic prescriptions (AOR 3.0, CI 2.2-4.2), greater age (AOR 1.3, CI 1.2-1.4 for each 10-year increment), number of prescriptions (AOR 1.1, CI 1.1-1.1 for each additional prescription), and a prescription for buprenorphine (AOR 9.5, CI 3.0-30.0), fentanyl (AOR 3.5, CI 1.7-7.0), hydromorphone (AOR 3.3, CI 1.4-7.5), methadone (AOR 4.9, CI 2.5-9.6), or oxycodone (AOR 1.9, CI 1.4-2.6). Patients receiving a daily average of >40 morphine milligram equivalents had an OR of 12.2 (CI 9.2-16.0). CONCLUSIONS: Patients being prescribed opioid analgesics frequently or at high dosage face a substantial overdose risk. Prescription monitoring programs might be the best way for prescribers to know their patients' prescription histories and accurately assess overdose risk.

Increased fall-related mortality rates in New Mexico, 1999-2005.

OBJECTIVE: In 2000, fall injuries affected 30% of U.S. residents aged ≥65 years and cost $19 billion. In 2005, New Mexico (NM) had the highest fall-related mortality rate in the United States. We described factors associated with these elevated fall-related mortality rates. METHODS: To better understand the epidemiology of fatal falls in NM, we used state and national (Web-based Injury Statistics Query and Reporting System) vital records data for 1999-2005 to identify unintentional falls that were the underlying cause of death. We calculated age-adjusted mortality rates, rate ratios (RRs), and 95% confidence intervals (CIs) by sex, ethnicity, race, and year. RESULTS: For 1999-2005 combined, NM's fall-related mortality rate (11.7 per 100,000 population) was 2.1 times higher than the U.S. rate (5.6 per 100,000 population). Elevated RRs persisted when stratified by sex (male RR=2.0, female RR=2.2), ethnicity (Hispanic RR=2.5, non-Hispanic RR=2.1), race (white RR=2.0, black RR=1.7, American Indian RR=2.3, and Asian American/Pacific Islander RR=3.1), and age (≥50 years RR=2.0, <50 years RR=1.2). Fall-related mortality rates began to increase exponentially at age 50 years, which was 15 years younger than the national trend. NM non-Hispanic individuals had the highest demographic-specific fall-related mortality rate (11.8 per 100,000 population, 95% CI 11.0, 12.5). NM's 69.5% increase in fall-related mortality rate was approximately twice the U.S. increase (31.9%); the increase among non-Hispanic people (86.2%) was twice that among Hispanic people (43.5%). CONCLUSIONS: NM's fall-related mortality rate was twice the U.S. rate; exhibited a greater increase than the U.S. rate; and persisted across sex, ethnicity, and race. Fall-related mortality disproportionately affects a relatively younger population in NM. Characterizing fall etiology will assist in the development of effective prevention measures.

Importance of employee vaccination against influenza in preventing cases in long-term care facilities.

OBJECTIVE: Employees of long-term care facilities (LTCFs) who have contact with residents should be vaccinated against influenza annually to reduce influenza incidence among residents. This investigation estimated the magnitude of the benefit of this recommendation. METHODS: The New Mexico Department of Health implemented active surveillance in all of its 75 LTCFs during influenza seasons 2006-2007 and 2007-2008. Information about the number of laboratory-confirmed cases of influenza and the proportion vaccinated of both residents and direct-care employees in each facility was collected monthly. LTCFs reporting at least 1 case of influenza (defined alternately by laboratory confirmation or symptoms of influenza-like illness [ILI]) among residents were compared with LTCFs reporting no cases of influenza. Regression modeling was used to obtain adjusted odds ratios (aORs) and 95% confidence intervals (CIs) for the association between employee vaccination coverage and the occurrence of influenza outbreaks. Covariates included vaccination coverage among residents, the staff-to-resident ratio, and the proportion of filled beds. RESULTS: Seventeen influenza outbreaks were reported during this 2-year period of surveillance. Eleven of these were laboratory confirmed (n = 21 residents) and 6 were defined by ILI (n = 40 residents). Mean influenza vaccination coverage among direct-care employees was 51% in facilities reporting outbreaks and 60% in facilities not reporting outbreaks (P = .12). Increased vaccination coverage among direct-care employees was associated with fewer reported outbreaks of laboratory-confirmed influenza (aOR, 0.97 [95% CI, 0.95-0.99]) and ILI (aOR, 0.98 [95% CI, 0.96-1.00]). CONCLUSIONS: High vaccination coverage among direct-care employees helps to prevent influenza in LTCFs.

Survey of American Indian alcohol statutes, 1975-2006: evolving needs and future opportunities for tribal health.

OBJECTIVE: American Indians and Alaska Natives have the nation's highest morbidity and mortality owing to alcohol but also have opportunities to employ policies that could reduce the harmful effects of drinking. As sovereign nations, federally recognized tribes can adopt policies that are highly likely to have a beneficial impact on alcohol problems. The most recently published nationwide research on American Indian alcohol policies (conducted some 30 years ago) suggested that tribal policies may help minimize adverse consequences related to drinking. However, much has changed in Indian country during the last few decades, including redefinitions of relationships among tribes, states, and the federal government; recognition of tribes not previously acknowledged by federal authorities; and the advent of gaming and casinos. These developments raise numerous questions regarding the adoption and implementation of policies pertaining to alcohol. METHOD: This project used the Federal Register to catalog alcohol statutes adopted by the 334 federally recognized tribes in the lower 48 states between 1975 and 2006. Tribes that do not have an alcohol policy have, by default, retained federal prohibition. RESULTS: During the 30-year study period, the percentage of tribes with statutes that permit alcohol increased from 29.2% to 63.5%. Later policies showed increases in complexity, such as tribal licensing requirements and facility restrictions to accompany increases in gaming and tourism. CONCLUSIONS: These data are highly relevant to Native decision makers as they attempt to develop and implement policies that will minimize the harmful effects of alcohol among indigenous peoples.

Unintentional drug overdose death trends in New Mexico, USA, 1990-2005: combinations of heroin, cocaine, prescription opioids and alcohol.

AIMS: To determine the contribution of heroin, prescription opioids, cocaine and alcohol/drug combinations to the total overdose death rate and identify changes in drug overdose patterns among New Mexico subpopulations. DESIGN: We analyzed medical examiner data for all unintentional drug overdose deaths in New Mexico during 1990-2005. Age-adjusted drug overdose death rates were calculated by sex and race/ethnicity; we modeled overall drug overdose death adjusting for age and region. FINDINGS: The total unintentional drug overdose death rate in New Mexico increased from 5.6 per 100 000 in 1990 to 15.5 per 100 000 in 2005. Deaths caused by heroin, prescription opioids, cocaine and alcohol/drug combinations together ranged from 89% to 98% of the total. Heroin caused the most deaths during 1990-2005, with a notable rate increase in prescription opioid overdose death during 1998-2005 (58%). During 1990-2005, the 196% increase in single drug category overdose death was driven by prescription opioids alone and heroin alone; the 148% increase in multi-drug category overdose death was driven by heroin/alcohol and heroin/cocaine. Hispanic males had the highest overdose death rate, followed by white males, white females, Hispanic females and American Indians. The most common categories causing death were heroin alone and heroin/alcohol among Hispanic males, heroin/alcohol among American Indian males and prescription opioids alone among white males and all female subpopulations. CONCLUSIONS: Interventions to prevent drug overdose death should be targeted according to use patterns among at-risk subpopulations. A comprehensive approach addressing both illicit and prescription drug users, and people who use these drugs concurrently, is needed to reduce overdose death.

Prevalence of alcohol dependence among excessive drinkers in New Mexico.

BACKGROUND: Excessive alcohol consumption claims more than 75,000 lives in the United States each year. The prevalence of alcohol dependence among excessive drinkers is not well known. METHODS: Data from the 2002 Behavioral Risk Factor Surveillance System (BRFSS) in New Mexico were used to assess the prevalence of excessive drinking, including binge drinking, heavy drinking, alcohol-impaired driving, and alcohol dependence. RESULTS: Of 4,761 respondents, 16.5% were excessive drinkers; 14.4% binge drank and 1.8% were alcohol dependent. While the rates of alcohol dependence were higher among the youngest age group, males, those with some college education, and those of race/ethnicity other than White, non-Hispanic, only differences by age were statistically significant. The prevalence of alcohol dependence was the highest among those who reported alcohol-impaired driving in the past 30 days (15.9%), and was lower among those who reported heavy drinking (13.4%) and binge drinking (8.1%). CONCLUSIONS: Although 16.5% of New Mexico adults had at least 1 type of excessive drinking, only 1.8% of all adults met the criteria for alcohol dependence. Furthermore, only a minority of those who reported binge drinking, heavy drinking, or alcohol-impaired driving met the criteria for alcohol dependence. This suggests that most alcohol problems in New Mexico are likely due to excessive drinking among persons who are not alcohol dependent. The adverse health and social consequences associated with excessive drinking are not limited to those who are alcohol dependent, but extend to a broader range of problem drinkers across the population.

Unintentional prescription drug overdose deaths in New Mexico, 1994-2003.

BACKGROUND: New Mexico has the highest rate of drug-induced mortality in the United States. The contribution of prescription drugs to the total overdose death rate has not been adequately described. METHODS: A total of 1,906 unintentional drug overdose deaths occurring in 1994 to 2003 in New Mexico were analyzed. Unintentional drug overdose death was defined as death caused by prescription, illicit, or a combination of drugs, as determined by a pathologist. Deaths were investigated annually by the medical examiner and data were analyzed in 2004-2005. Rates and trends of total and prescription drug overdose death were calculated, decedent characteristics were analyzed, and common drug combinations causing death were described. RESULTS: The rate of unintentional prescription drug overdose death increased by 179% (1.9 to 5.3/100,000) from 1994 to 2003. A high percentage of prescription drug overdose decedents were white non-Hispanic (63.2%) and female (43.9%). These decedents were older and less frequently had alcohol listed as an additional cause of death than decedents of other drug overdose categories. Of all deaths caused by prescription drug(s) (n =765), 590 (77.1%) were caused by opioid painkillers, 263 (34.4%) by tranquilizers, and 196 (25.6%) by antidepressants. CONCLUSIONS: The rate of prescription drug overdose death in New Mexico increased significantly over the 10-year study period. Comprehensive surveillance of drug overdose deaths is recommended to describe their occurrence in the context of both medical and diverted use of prescription drugs. Understanding decedent profiles and the potential risk factors for prescription drug overdose death is crucial for effective drug overdose prevention education among healthcare providers.

The disparity change score: a new methodology to examine health disparities in New Mexico.

OBJECTIVES: One overarching goal of Healthy People 2010 is to eliminate health disparities. Reducing disparities improves the overall health status of a population but is a lengthy process. The disparity change score (DCS) is a method for tracking health disparities over time. METHODS: Rates, rate ratios, and DCSs were calculated to track disparities during two time periods by sex, race/ethnicity, education, and income for key health indicators. Time periods were 10 years apart for all death indicators; length between time periods varied for other indicators depending on data collection systems. RESULTS: Sex-, race/ethnicity-, education-, and income-based disparities and disparity changes for New Mexico were identified. In general, males, American Indians, and those with the lowest income and education experienced the greatest health disparities. Five disparities that are worsening were identified for targeted interventions, mainly for males (firearm-related death and suicide) and American Indians (diabetes death and influenza/pneumonia death), but also for white non-Hispanics (drug-related death). CONCLUSIONS: Examining disparities at one point in time discounts disparity change over time. The DCS can help identify large disparities that are worsening and toward which resources for targeted interventions can be redirected. New Mexico should consider interventions for the five key disparities identified in this study.

Unintentional methadone-related overdose death in New Mexico (USA) and implications for surveillance, 1998-2002.

AIMS: To determine death rates from methadone over time, to characterize methadone-related death and to discuss public health surveillance of methadone-related death. DESIGN: We analyzed medical examiner data for all unintentional drug overdose deaths in New Mexico, USA, between 1998 and 2002. MEASUREMENTS: Age-adjusted death rates for methadone-related death, logistic regression models for likelihood of methadone-related death among all unintentional drug overdose deaths and bivariate comparisons within methadone-related death. FINDINGS: Of 1120 drug overdose deaths during this period, there were 143 (12.8%) methadone-related deaths; the death rate decreased over the time period, averaging 1.6 per 100,000. Of 143 methadone-related deaths, 22.4% were due to methadone alone, 23.8% were due to methadone/prescription drugs (no illicit drugs), 50.3% were due to methadone/illicit drugs and 3.5% were due to methadone/alcohol. These groups were significantly different in demographics, health history and circumstances of death. Of 79 decedents (55.2%) with a known source of methadone, 68 obtained methadone through a physician prescription (31 for methadone maintenance treatment (MMT), 27 for managing pain and 10 had unknown reason for prescription). CONCLUSIONS: Methadone-related death rates and the proportion of methadone-related death among all drug overdose deaths decreased in New Mexico from 1998 to 2002. It is important for surveillance of methadone-related death to assess multiple drug causes, not just underlying cause. Also, methadone for pain management must be examined alongside MMT and when possible, methadone co-intoxication should be described in the context of other drugs causing death.

Inadequate supervision as a cause of injury deaths among young children in Alaska and Louisiana.

OBJECTIVE: Inadequate supervision of children has contributed to injuries. However, the association of inadequate supervision with injury events in children has not been quantified. The purpose of this study was to describe and quantify the role of inadequate supervision of children in injury deaths. METHODS: Injury deaths among children aged 0 to 6 years in Alaska during 1993 to 1995 and Louisiana during 1994 were classified using 10 child safety standards to assess the role of parent/caregiver supervision in the circumstances of injury death. RESULTS: The leading categories of injury death for both states combined were motor vehicle injury and fire-related injury. Of the classifiable injury deaths in both states (157 [77%] of 203 deaths), the most commonly violated safety standard was "children should be supervised by a responsible care provider" (64 deaths [41%]). Of these deaths, the caregiver was absent in 38%, and the caregiver increased the danger to the child in 17%. Male injury deaths more typically involved a supervision standard violation. Drowning and pedestrian deaths typically involved a supervision standard violation, whereas asphyxiation, homicide, and occupant motor vehicle injury deaths did not. CONCLUSION: Alaska and Louisiana child injury deaths were mostly attributed to preventable violations of 10 child safety standards, most commonly the supervision standard. The methods in this report were useful in identifying target populations and causes of death, which can be used to plan and implement interventions to improve supervision of children.

Methodological issues in the surveillance of poisoning, illicit drug overdose, and heroin overdose deaths in new Mexico.

New Mexico leads the nation in poisoning mortality, which has increased during the 1990s in New Mexico and the United States. Most of this increase has been due to unintentional deaths from illicit drug overdoses. Medical examiner and/or vital statistics data have been used to track poisoning deaths. In this study, the authors linked medical examiner and vital statistics records on underlying cause of death, coded using the International Classification of Diseases, Ninth Revision, to assess the extent to which these data sources agreed with respect to poisoning deaths. The authors used multiple-cause files, which are files with several causes listed for each death, to further assess poisoning deaths involving more than one drug. Using vital statistics or medical examiner records, 94.7% of poisoning deaths were captured by each source alone. For unintentional illicit drug and heroin overdose deaths, each data source alone captured smaller percentages of deaths. Deaths coded as E858.8 (unintentional poisoning due to other drugs) require linkage with medical examiner or multiple-cause records, because this code identifies a significant percentage of illicit drug overdose deaths but obscures the specific drug(s) involved. Surveillance of poisoning death should include the use of medical examiner records and underlying- and multiple-cause vital statistics records.

Usefulness of telephone risk factor surveys in the New Mexico border region.

BACKGROUND: We sought to assess prevalence of behavioral risk factors and evaluate the usefulness of survey data gathered by telephone in the New Mexico border region. METHODS: This study compared behavioral risk factor data gathered from two probability sample surveys administered in 1998-1999, one by means of a telephone interview and the second face to face. Prevalence estimates for medical care access, injury, and chronic disease risk factors were compared by survey mode, overall, and stratified by income level. RESULTS: Risk factor prevalence estimates based on telephone interviews resemble estimates obtained from face-to-face interviews. Although risk factor prevalence estimated from face-to-face interviews were in general slightly greater than those from telephone interviews, none of these differences reached statistical significance. When data for each respective survey were examined by income level, prevalence estimates for comparable income groups in both surveys were in general agreement and estimates within survey increased with declining income. CONCLUSION: In the New Mexico border region, telephone survey data appear to be reasonably valid and offer opportunities for population-based health research.
