Trends in U.S. Medical cannabis registrations, authorizing clinicians, and reasons for use from 2020 to 2022
Boehnke KF , Sinclair R , Gordon F , Hosanagar A , Roehler DR , Smith T , Hoots B . Ann Intern Med 2024 BACKGROUND: As medical cannabis availability increases, up-to-date trends in medical cannabis licensure can inform clinical policy and care. OBJECTIVE: To describe current trends in medical cannabis licensure in the United States. DESIGN: Ecological study with repeated measures. SETTING: Publicly available state registry data from 2020 to 2022. PARTICIPANTS: People with medical cannabis licenses and clinicians authorizing cannabis licenses in the United States. MEASUREMENTS: Total patient volume and prevalence per 10 000 persons in the total population, symptoms or conditions qualifying patients for licensure (that is, patient-reported qualifying conditions), and number of authorizing clinicians. RESULTS: In 2022, of 39 jurisdictions allowing medical cannabis use, 34 reported patient numbers, 19 reported patient-reported qualifying conditions, and 29 reported authorizing clinician numbers. Enrolled patients increased 33.3% from 2020 (3 099 096) to 2022 (4 132 098), with a corresponding 23.0% increase in the population prevalence of patients (175.0 per 10 000 in 2020 to 215.2 per 10 000 in 2022). However, 13 of 15 jurisdictions with nonmedical adult-use laws had decreased enrollment from 2020 to 2022. The proportion of patient-reported qualifying conditions with substantial or conclusive evidence of therapeutic value decreased from 70.4% (2020) to 53.8% (2022). Chronic pain was the most common patient-reported qualifying condition in 2022 (48.4%), followed by anxiety (14.2%) and posttraumatic stress disorder (13.0%). In 2022, the United States had 29 500 authorizing clinicians (7.7 per 1000 patients), 53.5% of whom were physicians. The most common specialties reported were internal or family medicine (63.4%), physical medicine and rehabilitation (9.1%), and anesthesia or pain (7.9%). LIMITATION: Missing data (for example, from California), descriptive analysis, lack of information on individual use patterns, and changing evidence base. CONCLUSION: Enrollment in medical cannabis programs increased overall but generally decreased in jurisdictions with nonmedical adult-use laws. Use for conditions or symptoms without a strong evidence basis continues to increase. Given these trends, more research is needed to better understand the risks and benefits of medical cannabis.

Prescription opioid misuse and use of alcohol and other substances among high school students - Youth Risk Behavior Survey, United States, 2019
Jones CM , Clayton HB , Deputy NP , Roehler DR , Ko JY , Esser MB , Brookmeyer KA , Hertz MF . MMWR Suppl 2020 69 (1) 38-46 Adolescence is an important period of risk for substance use initiation and substance use-related adverse outcomes. To examine youth substance use trends and patterns, CDC analyzed data from the 2009-2019 Youth Risk Behavior Survey. This report presents estimated prevalence of current (i.e., previous 30-days) marijuana use, prescription opioid misuse, alcohol use, and binge drinking and lifetime prevalence of marijuana, synthetic marijuana, cocaine, methamphetamine, heroin, injection drug use, and prescription opioid misuse among U.S. high school students. Logistic regression and Joinpoint analyses were used to assess 2009-2019 trends. Prevalence of current and lifetime substance use by demographics, frequency of use, and prevalence of co-occurrence of selected substances among students reporting current prescription opioid misuse are estimated using 2019 data. Multivariable logistic regression analysis was used to determine demographic and substance use correlates of current prescription opioid misuse. Current alcohol, lifetime cocaine, methamphetamine, heroin, and injection drug use decreased during 2009-2019. Lifetime use of synthetic marijuana (also called synthetic cannabinoids) decreased during 2015-2019. Lifetime marijuana use increased during 2009-2013 and then decreased during 2013-2019. In 2019, 29.2% reported current alcohol use, 21.7% current marijuana use, 13.7% current binge drinking, and 7.2% current prescription opioid misuse. Substance use varied by sex, race/ethnicity, grade, and sexual minority status (lesbian, gay, or bisexual). Use of other substances, particularly current use of alcohol (59.4%) and marijuana (43.5%), was common among students currently misusing prescription opioids. Findings highlight opportunities for expanding evidence-based prevention policies, programs, and practices that aim to reduce risk factors and strengthen protective factors related to youth substance use, in conjunction with ongoing initiatives for combating the opioid crisis. |
Parental monitoring and risk behaviors and experiences among high school students - Youth Risk Behavior Survey, United States, 2021
Dittus PJ , Li J , Verlenden JV , Wilkins NJ , Carman-McClanahan MN , Cavalier Y , Mercado MC , Welder LE , Roehler DR , Ethier KA . MMWR Suppl 2023 72 (1) 37-44 Parents have an important role in the promotion of healthy adolescent behaviors that can influence positive developmental trajectories and health outcomes. Parental monitoring is a central component of the parent-child relationship with the potential to reduce adolescent risk behaviors. Data from CDC's 2021 nationally representative Youth Risk Behavior Survey were used to describe the prevalence of parental monitoring reported by U.S. high school students and examine associations between parental monitoring and adolescent behaviors and experiences. Behaviors and experiences included sexual behaviors, substance use, violence, and indicators of poor mental health. This report marks the first national assessment of parental monitoring among U.S. high school students. Point prevalence estimates and corresponding 95% CIs were generated in the bivariate analyses between parental monitoring and the outcomes, stratified by demographic characteristics (sex, race and ethnicity, sexual identity, and grade). Multivariable logistic regression analyses were conducted to estimate the main effects of parental monitoring (categorized as high = always or most of the time and low = never, rarely, or sometimes) for each outcome, controlling for all demographics. Overall, 86.4% of students reported that their parents or other adults in their family know where they are going or with whom they will be all or most of the time. Reports of high parental monitoring were protective for all risk behaviors and experiences, with models controlling for sex, race and ethnicity, sexual identity, and grade. Results highlight the need for public health professionals who develop public health interventions and programs to conduct further research on the relation between parental monitoring and student health outcomes. |
Using transformer-based topic modeling to examine discussions of Delta-8 tetrahydrocannabinol: Content analysis
Smith BP , Hoots B , DePadilla L , Roehler DR , Holland KM , Bowen DA , Sumner SA . J Med Internet Res 2023 25 e49469 BACKGROUND: Delta-8 tetrahydrocannabinol (THC) is a psychoactive cannabinoid found in small amounts naturally in the cannabis plant; it can also be synthetically produced in larger quantities from hemp-derived cannabidiol. Most states permit the sale of hemp and hemp-derived cannabidiol products; thus, hemp-derived delta-8 THC products have become widely available in many state hemp marketplaces, even where delta-9 THC, the most prominently occurring THC isomer in cannabis, is not currently legal. Health concerns related to the processing of delta-8 THC products and their psychoactive effects remain understudied. OBJECTIVE: The goal of this study is to implement a novel topic modeling approach based on transformers, a state-of-the-art natural language processing architecture, to identify and describe emerging trends and topics of discussion about delta-8 THC from social media discourse, including potential symptoms and adverse health outcomes experienced by people using delta-8 THC products. METHODS: Posts from January 2008 to December 2021 discussing delta-8 THC were isolated from cannabis-related drug forums on Reddit (Reddit Inc), a social media platform that hosts the largest web-based drug forums worldwide. Unsupervised topic modeling with state-of-the-art transformer-based models was used to cluster posts into topics and assign labels describing the kinds of issues being discussed with respect to delta-8 THC. Results were then validated by human subject matter experts. RESULTS: There were 41,191 delta-8 THC posts identified and 81 topics isolated, the most prevalent being (1) discussion of specific brands or products, (2) comparison of delta-8 THC to other hemp-derived cannabinoids, and (3) safety warnings. About 5% (n=1220) of posts from the resulting topics included content discussing health-related symptoms such as anxiety, sleep disturbance, and breathing problems. Until 2020, Reddit posts contained fewer than 10 mentions of delta-8-THC for every 100,000 cannabis posts annually. However, in 2020, these rates increased by 13 times the 2019 rate (to 99.2 mentions per 100,000 cannabis posts) and continued to increase into 2021 (349.5 mentions per 100,000 cannabis posts). CONCLUSIONS: Our study provides insights into emerging public health concerns around delta-8 THC, a novel substance about which little is known. Furthermore, we demonstrate the use of transformer-based unsupervised learning approaches to derive intelligible topics from highly unstructured discussions of delta-8 THC, which may help improve the timeliness of identification of emerging health concerns related to new substances. |
Marijuana use among pregnant and nonpregnant women of reproductive age, 2013-2019
Kobernik EK , Ford ND , Levecke M , Galang RR , Hoots B , Roehler DR , Ko JY . Subst Use Misuse 2023 1-9 BACKGROUND: Marijuana is the most commonly used federally illicit substance among reproductive-age women in the United States. Updated information on marijuana use in this population can inform clinical and public health interventions. METHODS: Data from the 2013-2019 National Survey on Drug Use and Health was used to report weighted prevalence estimates of marijuana use in the past month, past 2-12 months, and past year among women aged 18-44 years with self-reported pregnancy status. Bivariate analyses and general linear regression models with Poisson distribution using appropriate survey procedures identified factors associated with past-year marijuana use by pregnancy status. RESULTS: Among pregnant women, 4.9% (95% confidence interval [CI]: 4.1-5.6) reported marijuana use in the past month, 10.4% (95% CI: 9.3-11.5) in the past 2-12 months, and 15.2% (95% CI: 13.9-16.6) in the past year. Among nonpregnant women, 11.8% (95% CI: 11.5-12.0) reported marijuana use in the past month, 7.8% (95% CI: 7.6-8.0) in the past 2-12 months, and 19.5% (95% CI: 19.2-19.9) in the past year. After adjusting for sociodemographic characteristics, past-year marijuana use was 2.3-5.1 times more likely among pregnant, and 2.1 to 4.6 times more likely among nonpregnant women who reported past-year tobacco smoking, alcohol use, or other illicit drug use compared to those reporting no substance use. CONCLUSIONS: Pregnant and nonpregnant women reporting marijuana use, alone or with other substances, can benefit from substance use screening and treatment facilitation. |
Cannabis-involved emergency department visits among persons aged <25 years before and during the COVID-19 pandemic - United States, 2019-2022
Roehler DR , Smith Hth , Radhakrishnan L , Holland KM , Gates AL , Vivolo-Kantor AM , Hoots BE . MMWR Morb Mortal Wkly Rep 2023 72 (28) 758-765 To understand trends in U.S. cannabis-involved emergency department (ED) visits (i.e., those for which cannabis use was documented in the chief complaint or a discharge diagnosis) among young persons aged <25 years during the COVID-19 pandemic, CDC used National Syndromic Surveillance Program data to examine changes in ED visits during 2019-2022. Mean weekly cannabis-involved ED visits among all young persons were higher during the COVID-19 pandemic in 2020, 2021, and 2022, compared with corresponding periods in 2019. Large increases in cannabis-involved ED visits throughout the COVID-19 pandemic compared with prepandemic surveillance periods in 2019 were identified among persons aged ≤10 years. ED visit rates among children and adolescents aged 11-14 years did not differ by sex until the first half of the 2020-21 school year (2020, weeks 37-53), when ED visit rates among females surpassed those among males. Improving clinicians' awareness of rising cannabis-involved ED visits might aid in early diagnosis of cannabis intoxication among young persons. Further, increasing adults' knowledge regarding safe cannabis storage practices, strengthening youths' coping and problem-solving skills through evidence-based prevention programs, and modifying cannabis packaging to decrease appeal to youths might help prevent intentional and unintentional cannabis use. |
Unintentional ingestion of putative delta-8 tetrahydrocannabinol by two youth requiring critical care: a case report
Bradley EK , Hoots BE , Bradley ES , Roehler DR . J Cannabis Res 2023 5 (1) 9 BACKGROUND: Delta-8 tetrahydrocannabinol (THC) is a psychoactive cannabinoid from the cannabis plant that can be synthetically converted from cannabidiol (CBD). Most states permit the full or restricted sale of hemp and hemp-derived CBD products, and therefore, delta-8 THC products are on the rise. Delta-8 THC consumption can cause intoxication. Products are often sold in edible form and occasionally in packaging that appears similar to candy. Clinical presentations for delta-8 THC ingestions are understudied and may differ from those described for delta-9 THC ingestions. CASE PRESENTATION: This case report describes unintentional ingestions of putative delta-8 THC by two pediatric patients that results in admission to the pediatric intensive care unit. The ingestions were of putative delta-8 THC infused product that resembled popular candies. Both patients developed periods of bradypnea with continued intermittent periods of agitation. Medical intervention included observation, noninvasive positive pressure ventilation via high flow nasal cannula, and intubation-but was not needed for both patients. Although family noted ongoing irritability for the patients, both were discharged approximately 45 h after ingestion. Delta-8 THC ingestion is reliant on self-report. CONCLUSIONS: As the availability of delta-8 THC increases, along with associated pediatric exposures, it is imperative for health care providers to quickly recognize and provide adequate treatment. While there is no specific antidote for THC intoxication beyond supportive care, providers can play an important role in prevention by educating parents and guardians on safe cannabis storage and by documenting cases for adverse event monitoring. |
Self-Reported medical and nonmedical cannabis use: Results from the 2018 Behavioral Risk Factor Surveillance System in 14 states
Schauer GL , Roehler DR , Hoots BE . J Community Health 2022 47 (4) 641-649 As policies legalizing adult cannabis use increase in the United States, understanding and characterizing the proportion of individuals consuming cannabis for medical and nonmedical purposes is important to inform targeted health education efforts. Data came from 7672 adults (> = 18 years) with past month cannabis use who responded to questions about reason for cannabis use on the 2018 Behavioral Risk Factor Surveillance System survey in 14 states. State and aggregated data were analyzed using weighted frequencies for descriptive analyses, and prevalence ratios were computed to identify demographic and substance use characteristics associated with medical only use or use for both medical and nonmedical reasons (vs. nonmedical use). Overall, 28.6% (95% CI: 26.7, 30.4) of adults who use cannabis reported using cannabis medically, 34.2% (95% CI: 32.3, 36.2) nonmedically, and 37.2% (95% CI: 35.2, 39.2) both medically and nonmedically. Characteristics associated with medical only use (compared with nonmedical only use) included being female; aged > 45 years; out of work, a homemaker, or unable to work; having daily or near daily cannabis use; having past month cigarette use; having no past month alcohol use; self-reporting poor health; and ever having been diagnosed with certain chronic diseases. Medical only use of cannabis is the least prevalent reason for use; use for both medical and nonmedical reasons is the most prevalent. Monitoring reasons for cannabis use can aid states in understanding differences between medical and nonmedical cannabis users, providing context to use patterns, and targeting health education messages to appropriate audiences. |
Trends and characteristics of cannabis-associated emergency department visits in the United States, 2006-2018
Roehler DR , Hoots BE , Holland KM , Baldwin GT , Vivolo-Kantor AM . Drug Alcohol Depend 2022 232 109288 BACKGROUND: Cannabis policies are rapidly changing in the United States, yet little is known about how this has affected cannabis-associated emergency department (ED) visits. METHODS: We studied trends in cannabis-associated ED visits and identified differences by visit characteristics. Cannabis-associated ED visits from 2006 to 2018 were identified from the Agency for Healthcare Research and Quality's Healthcare Cost and Utilization Project's (HCUP) Nationwide Emergency Department Sample (NEDS). JoinPoint analysis was used to identify trends from 2006 to 2014, prior to medical coding changes in 2015, and Z-tests were used to compare annual rate changes from 2016 to 2018. Changes in rates from 2017 to 2018 were examined by visit characteristics. RESULTS: From 2006-2014, the rate of cannabis-associated ED visits increased, on average, 12.1% annually (p < 0.05), from 12.3 to 34.7 visits per 100,000 population. The rate increased 17.3% from 2016 to 2017 (p < 0.05) and 11.1% from 2017 to 2018 (p < 0.05). From 2017-2018, rates of visits increased for both males (8.7%; p < 0.05) and females (15.9%; p < 0.05). Patients 0-14 years and 25 years and older had significant rate increases from 2017 to 2018 as did the Midwest region (36.8%; p < 0.05), the Northeast (9.2%; p < 0.05), and the South (4.5%; p < 0.05). CONCLUSIONS: Cannabis-associated ED visits are on the rise and subgroups are at increased risk. Some potential explanations for increases in cannabis-associated ED visits include increased availability of cannabis products, increased use, and diversity of products available in marketplaces. Strategies are needed to prevent youth initiation, limit potentially harmful use among adults, and ensure safe storage where cannabis use is legal. |
Cannabis sales increases during COVID-19: Findings from Alaska, Colorado, Oregon, and Washington.
Schauer GL , Dilley JA , Roehler DR , Sheehy TJ , Filley JR , Broschart SC , Holland KM , Baldwin GT , Holmes-Chavez AK , Hoots BE . Int J Drug Policy 2021 98 103384 BACKGROUND AND AIMS: Following emergency declarations related to COVID-19 in the United States, many states issued stay-at-home orders and designated essential business categories. Most states allowed medical and/or non-medical adult-use cannabis retailers to remain open. This study assesses changes in cannabis sales across Alaska, Colorado, Oregon, and Washington before and during the pandemic. METHODS: Pre-tax sales data from cannabis marketplaces in four states were analyzed to identify trends from January 2018-December 2020. Mean monthly sales and relative percent change in mean monthly sales were compared by state from April-December (coinciding with the pandemic) in 2018, 2019, and 2020. Differences were assessed using the nonparametric Mann-Whitney-U test. RESULTS: Mean monthly cannabis sales in all four states were higher during the pandemic period in 2020 compared to the same period in 2019. Sales reached a three-year peak in Washington in May 2020 and in Alaska, Colorado, and Oregon in July 2020. From April-December, the percent change in mean monthly sales from 2019 to 2020 was significantly higher than 2018-2019 in all four states, though Alaska saw similar increases between 2018-2019 and 2019-2020. CONCLUSION: To date, cannabis sales in Alaska, Colorado, Oregon, and Washington have increased more during the COVID-19 pandemic than in the previous two years. In light of these increases, data monitoring by states and CDC is warranted to understand how patterns of use are changing, which populations are demonstrating changes in use, and how such changes may affect substance use and related public health outcomes. |
Development and validation of a syndrome definition to identify suspected nonfatal heroin-involved overdoses treated in emergency departments
Scholl L , Liu S , Vivolo-Kantor A , Board A , Stein Z , Roehler DR , McGlone L , Hoots BE , Mustaquim D , Smith H . J Public Health Manag Pract 2020 Publish Ahead of Print (4) 369-378 CONTEXT: The Centers for Disease Control and Prevention (CDC) works closely with states and local jurisdictions that are leveraging data from syndromic surveillance systems to identify meaningful changes in overdose trends. CDC developed a suspected nonfatal heroin overdose syndrome definition for use with emergency department (ED) data to help monitor trends at the national, state, and local levels. OBJECTIVE: This study assesses the percentage of true-positive unintentional and undetermined intent heroin-involved overdose (UUHOD) captured by this definition. DESIGN/SETTING: CDC applied the UUHOD definition to ED data available in CDC's National Syndromic Surveillance Program (NSSP). Data were analyzed from 18 states that shared access to their syndromic data in NSSP with the CDC overdose morbidity team. Data were analyzed using queries and manual reviews to identify heroin overdose diagnosis codes and text describing chief complaint reasons for ED visits. MEASURES: The percentage of true-positive UUHOD was calculated as the number of true-positives divided by the number of total visits captured by the syndrome definition. RESULTS: In total, 99 617 heroin overdose visits were identified by the syndrome definition. Among 95 323 visits identified as acute heroin-involved overdoses, based on reviews of chief complaint text and diagnosis codes, 967 (1.0%) were classified as possible intentional drug overdoses. Among all 99 617 visits, 94 356 (94.7%) were classified as true-positive UUHOD; 2226 (2.2%) and 3035 (3.0%) were classified as "no" and "maybe" UUHOD, respectively. CONCLUSION: Analysis of the CDC heroin overdose syndrome definition determined that nearly all visits were captured accurately for patients presenting to the ED for a suspected acute UUHOD. This definition will continue to be valuable for ongoing heroin overdose surveillance and epidemiologic analysis of heroin overdose patterns. CDC will evaluate possible definition refinements as new products and terms for heroin overdose emerge. |
Suspected nonfatal drug-related overdoses among youth in the US: 2016-2019
Roehler DR , Olsen EO , Mustaquim D , Vivolo-Kantor AM . Pediatrics 2020 147 (1) BACKGROUND AND OBJECTIVES: During the current drug overdose crisis, the United States is experiencing a significant number of overdose deaths, hospitalizations, and emergency department visits. Given the vulnerability of young persons to substance use, it is important to assess how this crisis affects the nation's youth. In this study, we investigate trends in suspected nonfatal drug-related overdoses (all-drugs, opioids, heroin, and stimulants) among youth using syndromic surveillance data from 2016 to 2019. METHODS: A retrospective analysis of emergency department syndromic surveillance data were used to detect quarterly trends in suspected drug overdoses from April 2016 through September 2019 among youth aged 0 to 10, 11 to 14, and 15 to 24 years. Syndrome definitions were developed using chief complaint free-text and discharge diagnosis codes to identify overdoses involving all-drugs, opioids, heroin, and stimulants. Pearson χ(2) tests detected quarter-to-quarter changes, and joinpoint regression analysis assessed trends over time. RESULTS: On average, there was a 2.0 increase for youth aged 0 to 10 years and a 2.3 increase for youth aged 11 to 14 years for suspected all-drug overdoses. Suspected heroin overdoses decreased by an average of 3.3 per quarter for youth aged 15 to 24 years. Among all age groups, suspected stimulant overdoses increased across the study period, 3.3 for 0 to 10-year-olds, 4.0 for 11- to 14-year-olds, and 2.3 for 15- to 24-year-olds. CONCLUSIONS: Suspected stimulant-involved drug overdoses appear to be rising among youth. These findings could inform targeted interventions, such as stimulant-focused prevention, and comprehensive approaches, including school-based prevention and other strategies to lower morbidity and mortality. |
Buprenorphine prescription dispensing rates and characteristics following federal changes in prescribing policy, 2017-2018: A cross-sectional study
Roehler DR , Guy GPJr , Jones CM . Drug Alcohol Depend 2020 213 108083 BACKGROUND: Expansion of buprenorphine for opioid use disorder treatment is a core component of the opioid overdose epidemic response. The Comprehensive Addiction and Recovery Act (CARA) of 2016 authorized nurse practitioners (NPs) and physician assistants (PAs) to obtain a DATA-waiver to prescribe buprenorphine. The objectives of this study are to examine national- and county-level buprenorphine prescription dispensing, patterns by patient demographics and clinician specialty, and county-level characteristics associated with buprenorphine dispensing. METHODS: Retrospective analysis of buprenorphine prescriptions dispensed from approximately 92% of all retail prescriptions in the US (2017-2018). Analyses include rates of buprenorphine prescriptions dispensed, by patient demographics and prescriber specialty, changes in buprenorphine prescriptions dispensed at the national- and county-level, and county-level characteristics associated with buprenorphine dispensing. RESULTS: Buprenorphine prescriptions dispensed increased by 9.1% nationally, from 40.7-44.4 per 1000 residents. From 2017 to 2018, NPs (351.9%) and PAs (257.3%) had the largest percent increases in dispensed buprenorphine prescriptions, accounting for 79.6% of the total increase. In 2018, county-level characteristics associated with high buprenorphine dispensing included. among others: greater potential buprenorphine treatment capacity, higher drug overdose death rates, and higher rates of Medicaid enrollment. Rural counties were associated with low buprenorphine dispensing. CONCLUSION: Buprenorphine dispensing rates increased in the US from 2017 to 2018, suggesting the addition of NPs and PAs by CARA has contributed to an increase in dispensed buprenorphine prescriptions. |
Nonfatal drug overdoses treated in emergency departments - United States, 2016-2017
Vivolo-Kantor AM , Hoots BE , Scholl L , Pickens C , Roehler DR , Board A , Mustaquim D , Smith Hth , Snodgrass S , Liu S . MMWR Morb Mortal Wkly Rep 2020 69 (13) 371-376 In 2017, drug overdoses caused 70,237 deaths in the United States, a 9.6% rate increase from 2016 (1). Monitoring nonfatal drug overdoses treated in emergency departments (EDs) is also important to inform community prevention and response activities. Analysis of discharge data provides insights into the prevalence and trends of nonfatal drug overdoses, highlighting opportunities for public health action to prevent overdoses. Using discharge data from the Healthcare Cost and Utilization Project's (HCUP) Nationwide Emergency Department Sample (NEDS), CDC identified nonfatal overdoses for all drugs, all opioids, nonheroin opioids, heroin, benzodiazepines, and cocaine and examined changes from 2016 to 2017, stratified by drug type and by patient, facility, and visit characteristics. In 2017, the most recent year for which population-level estimates of nonfatal overdoses can be generated, a total of 967,615 nonfatal drug overdoses were treated in EDs, an increase of 4.3% from 2016, which included 305,623 opioid-involved overdoses, a 3.1% increase from 2016. From 2016 to 2017, the nonfatal overdose rates for all drug types increased significantly except for those involving benzodiazepines. These findings highlight the importance of continued surveillance of nonfatal drug overdoses treated in EDs to inform public health actions and, working collaboratively with clinical and public safety partners, to link patients to needed recovery and treatment resources (e.g., medication-assisted treatment). |
Regional trends in suspected synthetic cannabinoid exposure from January 2016 to September 2019 in the United States
Roehler DR , Hoots BE , Vivolo-Kantor AM . Drug Alcohol Depend 2019 207 107810 BACKGROUND: The unpredictable physiologic and pharmacologic effects of synthetic cannabinoids (SCs) are continuously changing as the chemical structure of SCs evolve to avoid classification as a Schedule I drug under the Controlled Substances Act in the U.S. This results in unpredictable pharmacologic effects and subsequent sequelae. Little is known about national or regional trends of SC clusters. The objective of this study is to investigate trends in SC exposure using emergency department (ED) syndromic data. METHODS: We analyzed ED syndromic data to detect quarterly trends from January 2016 through September 2019 for SC-related exposures within 59 jurisdictions in 47 states by U.S. region. Pearson chi-square tests detected quarter-to-quarter changes and Joinpoint regression assessed trends over time. RESULTS: From January 2016 to September 2019, 21,714 of 303.5 million ED visits involved suspected SC exposures. Nationally, SC-related exposures decreased by 1.9 % (p = .04) on average per quarter, yet exposures increased in the Midwest by 6.3 % (p = .002) and in the Northeast by 3.2 % (p = .03) on average per quarter, and decreased on average per quarter by 7.7% (p </= .001) in the Southeast and 11.4 % in the West (p </= .001). Known SC exposures that may align with clusters were identified in quarter-to-quarter monitoring. CONCLUSIONS: Only a small proportion of ED visits were related to suspected SC exposure. Although we did identify a small decrease in national SC exposures, there was wide variation by region. Additional efforts are needed to understand variation and to develop prevention and response strategies. |
Prevalence of drink-driving among adults in China: a nationally representative survey in 2010
Xiao D , Pengpeng Y , Yichong L , Leilei D , Limin W , Shults RA , Roehler DR , Yee SL . Traffic Inj Prev 2016 18 (8) 0 OBJECTIVE: We examined the prevalence of and characteristics associated with drink-driving in China. We compared this study's drink-driving findings with those from the United States to explore how effective traffic safety interventions from Western cultures might be adapted for use in China. METHODS: Data from the 2010 China Chronic Disease and Risk Factor Survey were analyzed to describe the prevalence and characteristics associated with drink-driving in China. RESULTS: Overall, 1.5% of Chinese adults reported drink-driving in the past 30 days-3% of males and 0.1% of females. However, among males who had driven a vehicle in the past 30 days and consumed at least one alcoholic beverage in the past 30 days, 19% reported drink-driving during the 30-day period. Excessive drinking, binge drinking, nonuse of seat belts, and having been injured in a road traffic crash in the past year were most strongly associated with drink-driving among males. CONCLUSION: Drink-driving is prevalent among male drivers in China. Although large differences exist between China and the United States in the proportion of adults who drive, the proportion who consume alcohol, and some of the personal characteristics of those who drink and drive, similarities between the two countries are present in patterns of risk behaviours among drink-driving. To reduce injuries and deaths from drink-driving, effective interventions from Western cultures need to be tailored for adoption in China. |
Helmets for Kids: evaluation of a school-based helmet intervention in Cambodia

Inj Prev 2015 22 (1) 52-8 OBJECTIVE: This paper analyses helmet use before and after implementing Helmets for Kids, a school-based helmet distribution and road safety programme in Cambodia. METHODS: Nine intervention schools (with a total of 6721 students) and four control schools (with a total of 3031 students) were selected using purposive sampling to target schools where students were at high risk of road traffic injury. Eligible schools included those where at least 50% of students commute to school on bicycles or motorcycles, were located on a national road (high traffic density), had few or no street signs nearby, were located in an area with a history of crash injuries and were in a province where other Cambodia Helmet Vaccine Initiative activities occur. Programme's effectiveness at each school was measured through preintervention and postintervention roadside helmet observations of students as they arrived or left school. Research assistants conducted observations 1-2 weeks preintervention, 1-2 weeks postintervention, 10-12 weeks postintervention and at the end of the school year (3-4 months postintervention). RESULTS: In intervention schools, observed student helmet use increased from an average of 0.46% at 1-2 weeks preintervention to an average of 87.9% at 1-2 weeks postintervention, 83.5% at 10-12 weeks postintervention and 86.5% at 3-4 months postintervention, coinciding with the end of the school year. Increased helmet use was observed in children commuting on bicycle or motorcycle, which showed similar patterns of helmet use. Helmet use remained between 0.35% and 0.70% in control schools throughout the study period. CONCLUSIONS: School-based helmet use programmes that combine helmet provision and road safety education might increase helmet use among children. |
Motorcycle helmet attitudes, behaviours and beliefs among Cambodians
Roehler DR , Sann S , Kim P , Bachani AM , Campostrini S , Florian M , Sidik M , Blanchard C , Sleet DA , Hyder AA , Ballesteros MF . Int J Inj Contr Saf Promot 2013 20 (2) 179-83 Motorcycle fatalities are increasing at an alarming rate in many South-East Asian countries, including Cambodia. Through brief face-to-face roadside interviews in Phnom Penh and four other Cambodian provinces, this article assesses Cambodian motorcyclists' attitudes, behaviours and beliefs related to motorcycle helmets. Out of 1016 motorcyclists interviewed, 50% were drivers, 40% were older passengers and 10% were child passengers. More drivers (50%) reported consistently wearing helmets, compared with older passengers (14%). Saving their life in the event of a crash was the impetus for drivers and older passengers to wear a helmet (96% and 98%, respectively). The top barriers to helmet use were: (1) 'depends on where I drive,' (2) 'I forget' and (3) 'inconvenient' or 'uncomfortable'. These descriptive findings were instrumental in shaping the Cambodian Helmet Vaccine Initiative passenger campaign to reduce the motorcycle-related injuries and fatalities to support the United Nations Decade of Action for Road Safety. |
Trends in prevalence, knowledge, attitudes, and practices of helmet use in Cambodia: results from a two year study
Bachani AM , Branching C , Ear C , Roehler DR , Parker EM , Tum S , Ballesteros MF , Hyder AA . Injury 2013 44 Suppl 4 S31-7 INTRODUCTION: Road traffic injuries (RTIs) are a major cause of both morbidity and mortality globally. Relative to countries with similar economic patterns both within and outside of South-East Asia, Cambodia's road traffic fatality rate is high, with motorcyclists accounting for more than half of all fatalities as a result of head injuries. Despite the initiation of national motorcycle helmet legislation for Cambodian drivers in 2009, helmet use among both drivers and passengers remains low. METHODS: This study adopted a two-pronged approach to assess the current status of and knowledge, attitudes, and practices (KAPs) towards helmet use among drivers and passengers in five provinces in Cambodia. The objective was to better understand helmet use over a two year period since the introduction of the 2009 legislation. Researchers conducted both (1) direct observation of daytime and nighttime helmet use (January 2011-January 2013) and (2) roadside KAP interviews with motorcyclists (November 2010-November 2012). RESULTS: The observed helmet rate across all study sites was 33% during nighttime and 48% during daytime, with proportions up to ten times higher among drivers compared with passengers. Self-reported helmet use was higher than observed use. Within the past 30 days, 60% of respondents reported that they "always" wore a helmet when they were drivers while only 24% reported they "always" wore a helmet as a passenger. Reported barriers for use among drivers included: "driving route", "forgetfulness", and "inconvenience/discomfort." CONCLUSION: Despite awareness of the protective value of helmets, motorcycle helmet use rates remain low in Cambodia. Many misconceptions remain in Cambodia regarding helmet use, including that they are unnecessary for short distance or at low speeds. These serve as an important barrier to helmet use, which, if dispelled and coupled with visible and regular enforcement, may significantly reduce the number of motorcycle-related injuries and fatalities. |
Surveillance of road crash injuries in Cambodia: an evaluation of the Cambodia road crash and victim information system (RCVIS)
Parker EM , Ear C , Roehler DR , Sann S , Sem P , Ballesteros MF . Traffic Inj Prev 2013 15 (5) 477-82 ABSTRACT Objective: Worldwide, 1.24 million deaths and 20-50 million road crash injuries occur annually, with a disproportionate burden on low and middle-income countries. Facing continued growth in motorized vehicles, Cambodia has begun to address road safety, including the creation of a nationwide road crash surveillance system, the Road Crash and Victim Information System (RCVIS). This study evaluates RCVIS to understand whether road crash injuries are being monitored efficiently and effectively and to identify areas for improvement. METHODS: We used the CDC Guidelines for Evaluating Public Health Surveillance Systems as an evaluation framework. To assess system attributes, we conducted in-person interviews with Cambodian road safety stakeholders, including representatives from the Ministries of Health and Interior, and reviewed RCVIS annual reports and system-operation documents. Characteristics assessed include usefulness, flexibility, acceptability, sensitivity, representativeness, data quality, and timeliness. RESULTS: The Cambodian government uses RCVIS data extensively for road safety planning purposes. RCVIS participation varies by type of data source, with 100% of police districts and 65% of hospitals reporting in 2010. Representativeness over time is a limitation-between 2007 and 2008, the number of reporting hospitals decreased from 65 to 42. From 2007 to 2010, the number of non-fatal injuries reported to RCVIS decreased by 35%, despite rapid growth in vehicle registrations. The system is timely, with annual reports disseminated within 10 months to more than 250 stakeholders. CONCLUSION: RCVIS provides a strong foundation for the surveillance of road crash injuries and fatalities in Cambodia. Differences in participation by data source and reduced hospital participation over time affect data representativeness and may indicate issues with acceptability. Recommendations include working with hospitals to standardize reporting procedures and to increase awareness about the usefulness of the data they collect. |
NCIPC's contribution to global injury and violence prevention: past, present, and future
Mahendra RR , Roehler DR , Degutis LC . J Safety Res 2012 43 (4) 271-7 Injuries and violence impact millions across the globe each year. For the past 20 years, the National Center for Injury Prevention and Control (NCIPC) at the Centers for Disease Control and Prevention (CDC) has assembled the largest cadre of injury and violence prevention experts in the world to reduce the burden of injuries and violence domestically and to inform global injury and violence prevention efforts. This article focuses on NCIPC's global injury and violence prevention work that involves: increasing awareness of the preventability of injury and violence, partnerships to promote injury research and best practices; establishing standards and guidance for data collection; building capacity through training and mentoring; and supporting evidence-based strategies. To decrease the global burden, the authors propose priority setting to maximize the development and sustainability of financial and human resources for injury and violence prevention. Impact on Industry: The authors call for increased capacity and resources for global injury and violence prevention. |
