Recreational cannabis legalization and pediatric exposures in Massachusetts, United States.

INTRODUCTION: In Massachusetts, US, medical cannabis legalisation was associated with increased paediatric cannabis exposure cases, including emergency department (ED) visits and hospitalizations. The impact of recreational cannabis legalisation (RCL) on paediatric exposures in Massachusetts has yet to be studied. METHODS: To compare the incidences before and after RCL in Massachusetts, US, we queried the data on paediatric cannabis exposure cases in 2016-2021 from the Centre for Healthcare and Analysis and Injury Surveillance Programme at the Massachusetts Department of Public Health. The pre-and post-legalisation phases comprised the periods between 2016-2018 and 2019-2021, respectively. Cannabis-related exposure cases included ED visits and hospitalizations among children and young adolescents of 0-19 years old. RESULTS: During the 6-year period (2016-2021), 2357 ED visits and 538 hospitalizations related to cannabis exposure among children and teenagers (0-19 years) were reported in Massachusetts. The incidence of ED visits for all age groups increased from 18.5 per 100 000 population before RCL to 31.0 per 100 000 population (incidence rate ratio (IRR), 1.6; 95% CI, 1.5 to 1.8). Children in the age groups of 0-5 and 6-12 years experienced the highest increase in cannabis-related ED visits. Additionally, the incidence of hospitalisation due to cannabis intoxication substantially increased following RCL (IRR, 2.2; 95% CI, 1.8 to 2.7), a 126% increase. CONCLUSIONS: Cannabis-related ED visits and hospitalizations among children and teenagers increased after recreational cannabis became legal in Massachusetts, US. Further efforts are warranted to prevent the unintentional impact of RCL, especially considering substantial increases in cannabis exposure cases among young children.

Unintentional Window Falls in Children and Adolescents.

OBJECTIVE: Unintentional window falls represent a preventable source of injury and death in children. Despite major campaigns in some larger cities, there continue to be unintentional falls from windows throughout the United States. We aimed to identify risk factors and trends in unintentional window falls in the pediatric population in a national and regional sample. METHODS: A retrospective analysis of annual emergency department (ED) visits from the National Electronic Injury Surveillance System using product codes specific to windows, as well as patient encounters for unintentional window falls from January 2007 to August 2017 using site-specific trauma registries from 10 tertiary care children's hospitals in New England. National and state-specific census population estimates were used to compute rates per 100,000 population. RESULTS: There were 38,840 ED visits and 496 regional patients who unintentionally fell from a window across the study period between 0 and 17 years old. The majority of falls occurred in children under the age of 6 and were related to falls from a second story or below. A decreased trend in national ED visits was seen, but no change in rates over time for regional trauma center encounters. A high number of falls was found to occur in smaller cities surrounding metropolitan areas and from single family residences. CONCLUSIONS: Falls from windows represent a low proportion of overall types of unintentional sources of injury in children but are a high risk for severe disability. These results provide updated epidemiologic data for targeted intervention programs, as well as raise awareness for continued education and advocacy.

Firearms training: what is actually taught?

INTRODUCTION: Firearm safety instructors and public health professionals are natural allies in the quest to prevent firearm injuries. We audited basic firearm classes to provide information that can help familiarise public health professionals and others with the content covered. METHODS: With the advice of expert instructors, we created an audit form. Volunteers audited 20 basic firearm classes in seven north-eastern states. RESULTS: All trainers covered a wide variety of safety issues. Some specific basics were covered in 90+% of the classes, including how to safely load/unload a gun, keeping your finger off the trigger until ready to shoot, and being aware of your target and what is behind it. In 50%-75% of the classes, the trainer covered topics such as operating a safety, clearing jams and cartridge malfunctions, and recommended storing guns unloaded and locked when not in use. Few instructors covered firearm suicide prevention (10%) or domestic violence (10%). Most encouraged gun ownership, gun carrying, gun use in self-defence and membership in a gun rights group. DISCUSSION: From a public health standpoint, we would like to see more instructors covering topics such as firearm suicide and alternatives to gun use in self-defence, and to recommend safer storage of firearms.

Age Legislation and Off-Road Vehicle Injuries in Children.

BACKGROUND AND OBJECTIVES: In 2010, the Massachusetts Legislature passed a comprehensive law that restricted off-road vehicle (ORV) use by children <14 years old and regulated ORV use by children up to the age of 18 years. We aimed to examine the impact of the 2010 Massachusetts law on the rates of ORV-related injuries. METHODS: A retrospective analysis was performed of Massachusetts emergency department (ED) and inpatient discharges between 2002 and 2013 as found in the Center for Health Information and Analysis database by using external causes of injury codes specific to ORV-related injuries. Yearly population-based rates were compared before and after the implementation of the law (2002-2010 vs 2011-2013) by using Poisson regression analysis and segmented regression. RESULTS: There were 3638 ED discharges and 481 inpatient discharges for ORV-related injuries in children across the 12-year study period. After the implementation of the law, the rate of ED discharges declined by 33% in 0- to 9-year-olds, 50% in 10- to 13-year-olds, and 39% in 14 to 17-year-olds (P < .0001). There was no significant decline in ED discharges for 25- to 34-year-olds. Inpatient hospital discharges were also reduced by 41% in 0- to 17-year-olds after implementation (P < .001). CONCLUSIONS: As compared with adults (ages 25-34 years), the population-based ORV-related injury rate of residents <18 years old significantly declined after the passage of legislation that imposed age restrictions and other safeguards for youth riders.

The impact of the 2007 graduated driver licensing law in Massachusetts on the rate of citations and licensing in teenage drivers.

OBJECTIVE: We recently demonstrated that the 2007 Massachusetts Graduated Driving Licensing (GDL) law decreased the rate of motor vehicle crashes in teenage drivers. To better understand this decrease, we sought to examine the law's impact on the issuance of driving licenses and traffic citations to teenage drivers. METHODS: Citation and license data were obtained from the Massachusetts Department of Transportation. Census data were obtained from the Census Data Center. Two study periods were defined: pre-GDL (2002-2006) and post-GDL (2007-2012). Two populations were defined: the study population (aged 16-17) and the control population (aged 25-29). The rates of licenses per population were compared pre- vs. post-GDL for the study group. The numbers of total, state, and local citations per population were compared pre- vs. post-GDL for both populations. A sensitivity analysis was performed for the rates of citations using licenses issued as a denominator. RESULTS: While licenses per population obtained by the study group decreased over the entire period, there was no change in the rate of decrease per year pre- vs. post-GDL (2.0% vs. 1.4%; p=0.6392). In the study population, total, state, and local citations decreased post-GDL (17.8% vs. 8.1%, p<0.0001; 3.7% vs. 2.2%, p<0.0001; 14.1% vs. 5.8%, p<0.0001, respectively). In the control group, total and state citations did not change (26.7% vs. 23.9%, p=0.3606; 9.2% vs. 10.2%, p=0.3404, respectively), and local citations decreased (17.5% vs. 13.7%, p=0.0389). The rates of decrease per year for total, state, and local citations were significantly greater in the study population compared with control (p<0.0001, p=0.0002, p<0.0001, respectively). CONCLUSIONS: The 2007 GDL law in Massachusetts was associated with fewer traffic citations without a change in the rate of licenses issued to teenagers. These findings suggest that 2007 GDL may be improving driving habits as opposed to motivating teenagers to delay the issuing of licenses.

Impact of a State Law on Physician Practice in Sports-Related Concussions.

OBJECTIVE: To determine physician-reported adherence to and support of the 2010 Massachusetts youth concussion law, as well as barriers to care and clinical practice in the context of legislation. STUDY DESIGN: Primary care physicians (n = 272) in a large pediatric network were eligible for a cross-sectional survey in 2014. Survey questions addressed key policy and practice provisions: concussion knowledge, state regulations and training, practice patterns, referrals, patient characteristics, and barriers to care. Analyses explored relationships between practice and policy, adjusting for physician demographic and practice characteristics. RESULTS: The survey response rate was 64% among all responders (173 of 272). A total of 146 respondents who had evaluated, treated, or referred patients with a suspected sports-related concussion in the previous year were eligible for analysis. The vast majority (90%) of providers agreed that the current Massachusetts laws regarding sports concussions are necessary and support the major provisions. Three-quarters (74%) had taken a required clinician training course on concussions. Those who took training courses were significantly more likely to develop individualized treatment plans (OR, 3.6; 95% CI, 1.1-11.0). Physician training did not improve screening of youth with concussion for depression or substance use. Most physicians (77%) advised patients to refrain from computer, telephone, or television for various time periods. Physicians reported limited communication with schools. CONCLUSIONS: Primary care physicians report being comfortable with the diagnosis and management of concussions, and support statewide regulations; however, adherence to mandated training and specific legal requirements varied. Broader and more frequent training may be necessary to align current best evidence with clinical care and state-mandated practice.

Health care utilization and charges following the enactment of the 2007 Graduated Drivers Licensing Law in Massachusetts.

BACKGROUND: Graduated Drivers Licensing (GDL) programs phase in driving privileges for teenagers. In 2007, Massachusetts implemented a stricter version of the 1998 GDL law, with increased fines and education. This study evaluated the impact of the law on motor vehicle crash (MVC)-related health care utilization and charges. METHODS: Massachusetts government and US Census Bureau data were analyzed to compare the rates of MVC-related emergency department (ED) visits and hospital charges before (2002-2006) and after (2007-2011) the 2007 GDL law. Three driver age groups were studied: 16-17 (evaluating the law effect), 18-20 (evaluating the sustainability of the effect), and 25-29 years old (control group). RESULTS: MVC-related ED visits per population decreased after the law for all three age groups (16-17: 2326 to 713; 18-20: 2110 to 1304; 25-29: 1694 to 1228; per 100,000, p<0.001), but the decrease was greater amongst teenagers (16-17: -69%; 18-20: -38%) compared to the control group (-27%); p<0.001. MVC-related hospital charges per population also decreased for teenagers but increased for the control group (16-17: $2.70 m to $1.45 m; 18-20: $3.52 m to $2.26 m; 25-29: $1.86 m to $1.92 m; per 100,000, p<0.001). CONCLUSIONS: The 2007 GDL law in Massachusetts was associated with significant decreases in MVC-related health care utilization and hospital charges among teenage drivers.

The impact and sustainability of the graduated driver licensing program in preventing motor vehicle crashes in Massachusetts.

BACKGROUND: Graduated driving licensing (GDL) programs phase in driving privileges for teenagers. We aimed to evaluate the effect of the 2007 GDL law on the incidence of total motor vehicle crashes (tMVCs) and fatal motor vehicle crashes (fMVCs) among teenagers in Massachusetts. METHODS: The Fatality Analysis and Reporting System, the Missouri Census Data Center, and the Massachusetts Department of Transportation databases were all used to create and compare the incidence of tMVCs and fMVCs before (2002-2006) and after (2007-2011) the law enactment. The following three driver age groups were studied: 16 years to 17 years (evaluating the law effect), 18 years to 20 years (evaluating the sustainability of the effect), and 25 years to 29 years (control group). As a sensitivity analysis, we compared the incidence rates per population and per licenses issued. RESULTS: tMVCs decreased following the law for all three age groups (16-17 years, from 7.6 to 4.8 per 1,000 people, p < 0.0001; 18-20 years, from 8.5 to 6.4 per 1,000 people, p < 0.0001; 25-29 years, from 6.2 to 5.2 per 1,000 people, p < 0.0001), but the percentage decrease in tMVC rates was less in the control group (37%, 25%, and 15%, respectively; both p's < 0.0001). The rates of fMVC also decreased in the age groups of 16 years to 17 years (from 14.0 to 8.6 per 100,000 people, p = 0.0006), 18 years to 20 years (from 21.2 to 13.7 per 100,000 people, p < 0.0001), and 25 years to 29 years (from 14.4 to 11.0 per 100,000 people, p < 0.0001). All of these results were confirmed in the sensitivity analyses. CONCLUSION: The 2007 Massachusetts GDL was associated with a decreased incidence of teenager tMVCs and fMVCs, and the effect was sustainable. This study provides further support to develop, implement, enforce, and maintain GDL programs aimed at preventing MVCs and their related mortality in the young novice driver population. LEVEL OF EVIDENCE: Epidemiologic/prognostic study, level III.

Injury Prevention as an Integral Part of Health System Reform Efforts: Lessons Learned from Recently Enacted Massachusetts Laws.

Abstract-Injury is the leading cause of mortality in people younger than 44 years of age. Injury prevention laws and policies are not only effective in saving lives at a population level but are also remarkably cost-effective compared to most public health interventions. For example, the implementation of a stricter Massachusetts Graduated Driver Licensing Law in 2007 resulted in a very significant and rapid decrease in the rates of motor vehicle crashes of teenager drivers, saved thousands of lives, and resulted in more than $10 million dollars savings in health care costs over 5 years. We therefore suggest that trauma and injury prevention should be made a priority in any attempt at local, regional, or national health system reform.
