Falls and Fall Injuries Among Adults Aged ≥65 Years — United States, 2014

Falls are the leading cause of fatal and nonfatal injuries among adults aged ≥65 years (older adults). During 2014, approximately 27,000 older adults died because of falls; 2.8 million were treated in emergency departments for fall-related injuries, and approximately 800,000 of these patients were subsequently hospitalized.* To estimate the numbers, percentages, and rates of falls and fall injuries among older adults by selected characteristics and state, CDC analyzed data from the 2014 Behavioral Risk Factor Surveillance System (BRFSS) survey. In 2014, 28.7% of older adults reported falling; the estimated 29.0 million falls resulted in 7.0 million injuries. Known effective strategies for reducing the number of older adult falls include a multifactorial clinical approach (e.g., gait and balance assessment, strength and balance exercises, and medication review). Health care providers can play an important role in fall prevention by screening older adults for fall risk, reviewing and managing medications linked to falls, and recommending vitamin D supplements to improve bone, muscle, and nerve health and reduce the risk for falls.

Publicized Sobriety Checkpoint Programs

CONTEXT Publicized sobriety checkpoint programs deter alcohol-impaired driving by stopping drivers systematically to assess their alcohol impairment. Sobriety checkpoints were recommended in 2001 by the Community Preventive Services Task Force for reducing alcohol-impaired driving, based on strong evidence of effectiveness. Since the 2001 review, attention to alcohol-impaired driving as a U.S. public health problem has decreased. This systematic review was conducted to determine if available evidence supports the effectiveness of publicized sobriety checkpoint programs in reducing alcohol-impaired driving, given the current context. The economic costs and benefits of the intervention were also assessed. EVIDENCE ACQUISITION This review focused on studies that evaluated the effects of publicized sobriety checkpoint programs on alcohol-involved crash fatalities. Using Community Guide methods, a systematic search was conducted for studies published between July 2000 and March 2012 that assessed the effectiveness of publicized sobriety checkpoint programs. EVIDENCE SYNTHESIS Fourteen evaluations of selective breath testing and one of random breath testing checkpoints met the inclusion criteria for the systematic review, conducted in 2012. Ten evaluations assessed the effects of publicized sobriety checkpoint programs on alcohol-involved crash fatalities, finding a median reduction of 8.9% in this crash type (interquartile interval=-16.5%, -3.5%). Five economic evaluations showed benefit-cost ratios ranging from 2:1 to 57:1. CONCLUSIONS The number of studies, magnitude of effect, and consistency of findings indicate strong evidence of the effectiveness of publicized sobriety checkpoint programs in reducing alcohol-involved crash fatalities. Economic evidence shows that these programs also have the potential for substantial cost savings.

To estimate medical expenditures attributable to older adult falls using a methodology that can be updated annually to track these expenditures over time.

Predictors of rear seat belt use among U.S. adults, 2012.

INTRODUCTION Seat belt use reduces the risk of injuries and fatalities among motor vehicle occupants in a crash, but belt use in rear seating positions is consistently lower than front seating positions. Knowledge is limited concerning factors associated with seat belt use among adult rear seat passengers. METHODS Data from the 2012 ConsumerStyles survey were used to calculate weighted percentages of self-reported rear seat belt use by demographic characteristics and type of rear seat belt use enforcement. Multivariable regression was used to calculate prevalence ratios for rear seat belt use, adjusting for person-, household- and geographic-level demographic variables as well as for type of seat belt law in place in the state. RESULTS Rear seat belt use varied by age, race, geographic region, metropolitan status, and type of enforcement. Multivariable regression showed that respondents living in states with primary (Adjusted Prevalence Ratio (APR): 1.23) and secondary (APR: 1.11) rear seat belt use enforcement laws were significantly more likely to report always wearing a seat belt in the rear seat compared with those living in a state with no rear seat belt use enforcement law. CONCLUSIONS AND PRACTICAL APPLICATIONS Several factors were associated with self-reported seat belt use in rear seating positions. Evidence suggests that primary enforcement covering all seating positions is an effective intervention that can be employed to increase seat belt use and in turn prevent motor vehicle injuries to rear-seated occupants.

Driving self-regulation and ride service utilization in a multicommunity, multistate sample of U.S. older adults

ABSTRACT Objectives: This study examined a multicommunity alternative transportation program available 24 hours a day, 7 days a week, for any purpose, offering door-through-door service in private automobiles to members who either do not drive or are transitioning away from driving. Specific aims were to describe the characteristics of members by driving status and ride service usage of these members. Methods: Data came from administrative records maintained by a nonprofit ride service program and include 2,661 individuals aged 65+ residing in 14 states who joined the program between April 1, 2010, and November 8, 2013. Latent class analysis was used to group current drivers into 3 classes of driving status of low, medium, and high self-regulation, based on their self-reported avoidance of certain driving situations and weekly driving frequency. Demographics and ride service use rate for rides taken through March 31, 2014, by type of ride (e.g., medical, social, etc.) were calculated for nondrivers and drivers in each driving status class. Results: The majority of ride service users were female (77%) and aged 65–74 years (82%). The primary method of getting around when enrolling for the transportation service was by riding with a friend or family member (60%). Among the 67,883 rides given, nondrivers took the majority (69%) of rides. Medical rides were the most common, accounting for 40% of all rides. Conclusions: Reported ride usage suggests that older adults are willing to use such ride services for a variety of trips when these services are not limited to specific types (e.g., medical). Further research can help tailor strategies to encourage both nondrivers and drivers to make better use of alternative transportation that meets the special needs of older people.

Increasing smoke alarm operability through theory-based health education: a randomised trial

Background Although working smoke alarms halve deaths in residential fires, many households do not keep alarms operational. We tested whether theory-based education increases alarm operability. Methods Randomised multiarm trial, with a single arm randomly selected for use each day, in low-income neighbourhoods in Maryland, USA. Intervention arms: (1) Full Education combining a health belief module with a social-cognitive theory module that provided hands-on practice installing alarm batteries and using the alarms hush button; (2) Hands-on Practice social-cognitive module supplemented by typical fire department education; (3) Current Norm receiving typical fire department education only. Four hundred and thirty-six homes recruited through churches or by knocking on doors in 2005–2008. Follow-up visits checked alarm operability in 370 homes (85%) 1–3.5 years after installation. Main outcome measures: number of homes with working alarms defined as alarms with working batteries or hard-wired and number of working alarms per home. Regressions controlled for alarm status preintervention; demographics and beliefs about fire risks and alarm effectiveness. Results Homes in the Full Education and Practice arms were more likely to have a functioning smoke alarm at follow-up (OR=2.77, 95% CI 1.09 to 7.03) and had an average of 0.32 more working alarms per home (95% CI 0.09 to 0.56). Working alarms per home rose 16%. Full Education and Practice had similar effectiveness (p=0.97 on both outcome measures). Conclusions Without exceeding typical fire department installation time, installers can achieve greater smoke alarm operability. Hands-on practice is key. Two years after installation, for every three homes that received hands-on practice, one had an additional working alarm. Trial registration number http://www.clinicaltrials.gov number NCT00139126.

Perceptions of alcohol-impaired driving and the blood alcohol concentration standard in the United States

INTRODUCTION Although the number of alcohol-impaired driving (AID) fatalities has declined over the past several years, AID continues to be a serious public health problem. The purpose of this effort was to gain a better understanding of the U.S. driving populations perceptions and thoughts about the impacts of lowering the blood alcohol concentration (BAC) driving standard below.08% on AID, health, and other outcomes. METHODS A questionnaire was administered to a nationally representative sample of licensed drivers in the U.S. (n=1011) who were of age 21 or older on driving habits, alcohol consumption habits, drinking and driving habits, attitudes about drinking and driving, experiences with and opinions of drinking and driving laws, opinions about strategies to reduce drinking and driving, general concerns about traffic safety issues, and demographics. RESULTS One-third of participants supported lowering the legal BAC standard, and participants rated a BAC standard of .05% to be moderately acceptable on average. 63.9% indicated that lowering 30 the BAC to .05% would have no effect on their decisions to drink and drive. Nearly 60% of respondents lacked accurate knowledge of their states BAC standard. CONCLUSIONS Public support for lowering the BAC standard was moderate and was partially tied to beliefs about the impacts of a change in the BAC standard. The results suggest that an opportunity for better educating the driving population about existing AID policy and the implications for lowering the BAC level on traffic injury prevention. PRACTICAL APPLICATIONS The study results are useful for state traffic safety professionals and policy makers to have a better understanding of the publics perceptions of and thoughts about BAC standards. There is a clear need for more research into the effects of lowering the BAC standard on crashes, arrests, AID behavior, and alcohol-related behaviors.

Implementation of the Stopping Elderly Accidents, Deaths, and Injuries Initiative in Primary Care: An Outcome Evaluation

Background and Objectives Older adult falls pose a growing burden on the U.S. health care system. The Centers for Disease Control and Preventions Stopping Elderly Accidents, Deaths, and Injuries (STEADI) initiative was developed as a multifactorial approach to fall prevention that includes screening for fall risk, assessing for modifiable risk factors, and prescribing evidence-based interventions to reduce fall risk. The purpose of this study was to determine the impact of a STEADI initiative on medically treated falls within a large health care system in Upstate New York. Research Design and Methods This cohort study classified older adults who were screened for fall risk into 3 groups: (a) At-risk and no Fall Plan of Care (FPOC), (b) At-risk with a FPOC, and (c) Not-at-risk. Poisson regression examined the groups effect on medically treated falls when controlling for other variables. The sample consisted of 12,346 adults age 65 or older who had a primary care visit at one of 14 outpatient clinics between September 11, 2012, and October 30, 2015. A medically treated fall was defined as a fall-related treat-and-release emergency department visit or hospitalization. Results Older adults at risk for fall with a FPOC were 0.6 times less likely to have a fall-related hospitalization than those without a FPOC (p = .041), and their postintervention odds were similar to those who were not at risk. Discussion and Implications This study demonstrated that implementation of STEADI fall risk screening and prevention strategies among older adults in the primary care setting can reduce fall-related hospitalizations and may lower associated health care expenditures.

PW 0698 Empowering states to prevent motor vehicle injuries—tools from the CDC

Every day in the United States, over 100 people are killed and thousands more injured in motor vehicle crashes. The U.S. Centers for Disease Control and Prevention’s (CDC) National Center for Injury Prevention and Control works to prevent motor vehicle crash injuries and their resulting public health and economic burden. In traffic safety, translating research findings into actionable products is a top priority. In the U.S., many of the traffic safety strategies are implemented at the state level. One focus of CDC’s Transportation Safety Team is to create tools and products to empower states, decision makers, and partners to make data-driven and evidence-based decisions for prevention. These tools address a range of state needs and include an online cost-effectiveness calculator, implementation guides for community, tribal, and state programs, a mobility planning tool for older adults, and fact sheets covering a range of topics. As one example, the older adult mobility planning tool was created to help older adults, beginning at age 60, plan for future mobility changes that might increase their risk for motor vehicle crashes and falls. The planning tool was developed based on the trans-theoretical stages of change and iterative testing with older adults. The tool helps older adults think through how they will remain injury free and mobile as they age. This presentation will provide an overview of recent trends in motor vehicle crash injuries and deaths in the United States, CDC’s role in road safety, and of the various CDC tools, prevention products, and state implementation efforts. CDC’s Transportation Safety Team encourages the use of proven strategies for motor vehicle crash injury prevention. Supporting motor vehicle injury prevention in the U.S. ultimately supports global road safety targets including the Decade of Action for Road Safety and the 2030 Agenda for Sustainable Development targets 3.6 and 11.2.

How do older adult drivers self-regulate? Characteristics of self-regulation classes defined by latent class analysis ☆

PROBLEM Motor-vehicle crashes were the second leading cause of injury death for adults aged 65-84years in 2014. Some older drivers choose to self-regulate their driving to maintain mobility while reducing driving risk, yet the process remains poorly understood. METHODS Data from 729 older adults (aged ≥60years) who joined an older adult ride service program between April 1, 2010 and November 8, 2013 were analyzed to define and describe classes of driving self-regulation. Latent class analysis was employed to characterize older adult driving self-regulation classes using driving frequency and avoidance of seven driving situations. Logistic regression was used to explore associations between characteristics affecting mobility and self-regulation class. RESULTS Three classes were identified (low, medium, and high self-regulation). High self-regulating participants reported the highest proportion of always avoiding seven risky driving situations and the lowest driving frequency followed by medium and low self-regulators. Those who were female, aged 80years or older, visually impaired, assistive device users, and those with special health needs were more likely to be high self-regulating compared with low self-regulating. CONCLUSIONS AND PRACTICAL APPLICATIONS Avoidance of certain driving situations and weekly driving frequency are valid indicators for describing driving self-regulation classes in older adults. Understanding the unique characteristics and mobility limitations of each class can guide optimal transportation strategies for older adults.
