Cost-benefit analysis of a distracted pedestrian intervention.

OBJECTIVE: Cellphone ubiquity has increased distracted pedestrian behaviour and contributed to growing pedestrian injury rates. A major barrier to large-scale implementation of prevention programmes is unavailable information on potential monetary benefits. We evaluated net economic societal benefits of StreetBit, a programme that reduces distracted pedestrian behaviour by sending warnings from intersection-installed Bluetooth beacons to distracted pedestrians' smartphones. METHODS: Three data sources were used as follows: (1) fatal, severe, non-severe pedestrian injury rates from Alabama's electronic crash reporting system; (2) expected costs per fatal, severe, non-severe pedestrian injury-including medical cost, value of statistical life, work-loss cost, quality-of-life cost-from CDC and (3) prevalence of distracted walking from extant literature. We computed and compared estimated monetary costs of distracted walking in Alabama and monetary benefits from implementing StreetBit to reduce pedestrian injuries at intersections. RESULTS: Over 2019-2021, Alabama recorded an annual average of 31 fatal, 83 severe and 115 non-severe pedestrian injuries in intersections. Expected costs/injury were US$11 million, US$339 535 and US$93 877, respectively. The estimated distracted walking prevalence is 25%-40%, and StreetBit demonstrates 19.1% (95% CI 1.6% to 36.0%) reduction. These figures demonstrate potential annual cost savings from using interventions like StreetBit statewide ranging from US$18.1 to US$29 million. Potential costs range from US$3 208 600 (beacons at every-fourth urban intersection) to US$6 359 200 (every other intersection). CONCLUSIONS: Even under the most parsimonious scenario (25% distracted pedestrians; densest beacon placement), StreetBit yields US$11.8 million estimated net annual benefit to society. Existing data sources can be leveraged to predict net monetary benefits of distracted pedestrian interventions like StreetBit and facilitate large-scale intervention adoption.

Telehealth utilization barriers among Alabama parents of pediatric patients during COVID-19 outbreak.

BACKGROUND: Telehealth can improve access to evidence-based care at a lower cost for patients, especially those living in underserved and remote areas. The barriers to the widespread adoption of telehealth have been well documented in the literature. However, the barriers may not be the same for pediatric patients, who must rely on their parents or guardians to make healthcare decisions. This paper presents some of the leading barriers parents or guardians of pediatric patients report in using telehealth to meet their children's healthcare needs. METHODS: This cross-sectional survey was conducted in a tertiary care pediatric Emergency Department (ED) at a children's hospital in Alabama between September 2020 to December 2020. The parents or guardians of pediatric patients were asked about their reasons for not using telehealth despite having healthcare needs for their children, whether they canceled or rescheduled healthcare provider visits and facility visits, and whether the child's health conditions changed over the past three months. Descriptive analyses were conducted that explored the distribution of telehealth use across the variables listed above. RESULTS: Five hundred ninety-seven parents or guardians of pediatric patients participated in the survey, and 578 answered the question of whether they used telehealth or not over the past three months. Of them, 33.1% used telehealth, 54.3% did not, and 12.6% did not have healthcare needs for their child. The leading reason for not using telehealth was that the doctor or health provider did not give them a telehealth option, the second main reason was that they did not know what telehealth is, and the third leading reason was that the parents did not think telehealth would help meet healthcare needs for their child. CONCLUSIONS: This study highlights the telehealth utilization barriers among underserved pediatric populations, including the need for physicians to proactively offer telehealth options to parents or guardians of pediatric patients. Improving health literacy is of paramount importance, given that a substantial proportion of parents were not familiar with telehealth. Policymakers and healthcare organizations should raise awareness about the benefits of telehealth which can improve healthcare access for underserved pediatric patients.

Characteristics and outcomes associated with two asthma quality of care measures.

OBJECTIVE: We investigated asthma quality measures to understand patient characteristics associated with non-attainment of quality care and measure the association with asthma-related emergency department (ED) visits or inpatient hospitalizations (IPs). METHODS: Using administrative data from ALL Kids, Alabama's Children's Health Insurance Program, from 2013 to 2019 we calculated non-attainment of the Medication Management for Asthma (MMA) and Asthma Medication Ratio (AMR) quality measures. Patient characteristics and asthma-related ED visits and IPs associated with non-attainment of the MMA and AMR measures were assessed using logit regression models and Marginal effects at the mean. RESULTS: Among 2528 children with asthma, 53.2% failed to attain the MMA measure and 8.5% the AMR measure. Prior asthma-related ED visits or IP stays increased likelihood of non-attainment by 14.8 percentage points (95% CI 8.6-20.9) for MMA and 7.3 percentage points (95% CI 2.8-11.8) for AMR. Among 868 children (34.3%) with three years of continuous enrollment, AMR non-attainment was associated with a 6.1 percentage point increase in ED or IP utilization (95% CI 1.3-10.9), however MMA non-attainment was not associated with either outcome. Prior ED visit/IP stay was associated with a 17.2 percentage point (95% CI 8.3-26.1) increase in the likelihood of a subsequent ED visit/IP stay among those with non-attainment MMA and a 15.5 percentage point increase (95% CI 6.9-24.2) for non-attainment AMR. CONCLUSIONS: Patient characteristics associated with non-attainment of asthma quality measures presents actionable evidence to guide improvement efforts as non-attainment AMR increases the risk of subsequent ED visits and IP stays.

Disruption of Pediatric Emergency Department Use during the COVID-19 Pandemic.

OBJECTIVES: There is evidence of substantial declines in pediatric emergency department (ED) utilization in the United States in the first several months of the coronavirus disease 2019 (COVID-19) pandemic. Less is known about whether utilization changed differentially for socioeconomically disadvantaged children. This study examined how changes in pediatric ED visits during the initial months of the COVID-19 pandemic differed by two markers of socioeconomic disadvantage: minoritized race (MR) (compared with non-Hispanic White [NHW]), and publicly insured (compared with privately insured). METHODS: This study used electronic medical records from a large pediatric ED for the period January to June 2020. Three time periods in 2020 were compared with corresponding time periods in 2019. Changes in overall visits, visits for MR versus NHW children, and Medicaid-enrolled versus privately insured children were considered, and changes in the acuity mix of ED visits and share of visits resulting in inpatient admits were inspected. RESULTS: Compared with 2019, total ED visits declined in time period (TP) 1 and TP2 of 2020 (54.3%, 48.9%). Declines were larger for MR children (57.3%, 57.8%) compared with NHW children (50.5%, 39.3%), and Medicaid enrollees (56.5%, 52.0%) compared with privately insured (48.3%, 39.0%). The MR children group experienced steeper percentage declines in high-acuity visits and visits, resulting in inpatient admissions compared with NHW children. In contrast, there was little evidence of difference between TP0s of 2019 and 2020. CONCLUSIONS: The role of socioeconomic disadvantage and the potential effects on pediatric ED visits during COVID-19 is understudied. Because disadvantaged children sometimes lack access to a usual source of health care, this raises concerns about unmet health needs and worsening health disparities.

Contraception Use and Pregnancy Outcomes for Alabama Medicaid Enrollees: A Baseline Analysis Using 2012-2017 Data.

OBJECTIVES: Access to the full range of contraceptive methods, including long-acting reversible contraception (LARC), is key for preventing unintended pregnancies and improving health outcomes. In 2019, Alabama Medicaid started paying for LARC devices for postpartum women. In anticipation of evaluating the impact of this programmatic change, we conducted a baseline study exploring contraception use and pregnancy-end outcomes for enrollees before the change. METHODS: A retrospective cohort of women enrolled in Alabama Medicaid from 2012 to 2017 was examined. Outcomes include pregnancy-end events for all enrollees, teen pregnancy-end events, and short-interval (SI) pregnancy-end events. Pregnancy events in year t are matched to contraception in year t - 1. Contraception is categorized as "no evidence," short-acting contraception (SAC), LARC, and sterilization. Bivariate and multivariate models were estimated. RESULTS: Our final sample included 135,807 unique women who contributed 258,959 person-years. There was no evidence of contraception for 55.4% and evidence of SAC, LARC, and sterilization for 36.4%, 6.2%, and 2.0%, respectively. Relative risks for pregnancy-end events for SAC and LARC users were 0.63 (95% confidence interval [CI] 0.61-0.0.65) and 0.56 (95% CI 0.52-0.0.59), respectively, compared with women with no evidence of contraceptive use. For teen pregnancy-end events, relative risks for SAC and LARC users were 0.65 (95% CI 0.61-0.67) and 0.58 (95% CI 0.51-0.66), respectively. For SI pregnancy-end events, relative risks for SAC and LARC users were 0.71 (95% CI 0.68-0.76) and 0.40 (95% CI 0.34-0.46), respectively. CONCLUSIONS: LARC and SAC are associated with lower likelihood of pregnancy-end events compared with no evidence of contraception, and on average, LARC is associated with lower relative risk than SAC, especially for SI pregnancy-end events.

Environmental and organizational correlates and motivations for provider-sponsored health plan ownership in the post-reform era.

BACKGROUND: The 1980s to 1990s saw many health systems in the United States enter and exit the insurance market in the form of provider-sponsored health plans (PSHPs). Reforms and value-based reimbursement methods have stimulated health care organizations to reconsider PSHP as a logical strategy. PURPOSE: The aim of this study was to examine market and organizational factors associated with PSHP ownership and motivations for engaging in PSHP after health care reforms. The resource dependence theory was used as a theoretical lens. METHODOLOGY/APPROACH: A sequential quantitative to qualitative mixed-methods design was used. The quantitative analysis examined data for 5,849 U.S. hospitals. Results were synthesized with qualitative findings from 10 semistructured interviews representing eight health systems in five states. RESULTS: Organizational and environmental characteristics were significantly associated with PSHP ownership. Hospital and payer concentration, Medicare penetration, income, unemployment rate, government, and for-profit and metro area hospitals were associated with a lower likelihood of PSHP ownership. Salaried physician arrangements, clinically integrated network membership and adoption of other risk-bearing arrangements were associated with higher odds of PSHP ownership. Interviewees described PSHP as the culmination of the journey to value-based care and as a strategy to improve patient care, compete, and diversify revenue streams. CONCLUSIONS: Both market and organizational factors are important considerations for hospitals contemplating PSHP ownership, and motivations for ownership cover a broad range of financial, competitive, strategic, and mission-based goals. PRACTICE IMPLICATIONS: Hospitals considering PSHP ownership must carefully evaluate their competitive landscapes and organizational resources to ensure optimal conditions for this strategy. PSHP ownership has high start-up costs and requires a long-term organizational commitment.

Racial/ethnic and educational inequities in restrictive abortion policy variation and adverse birth outcomes in the United States.

BACKGROUND: To examine racial/ethnic and educational inequities in the relationship between state-level restrictive abortion policies and adverse birth outcomes from 2005 to 2015 in the United States. METHODS: Using a state-level abortion restrictiveness index comprised of 18 restrictive abortion policies, we conducted a retrospective longitudinal analysis examining whether race/ethnicity and education level moderated the relationship between the restrictiveness index and individual-level probabilities of preterm birth (PTB) and low birthweight (LBW). Data were obtained from the 2005-2015 National Center for Health Statistics Period Linked Live Birth-Infant Death Files and analyzed with linear probability models adjusted for individual- and state-level characteristics and state and year fixed-effects. RESULTS: Among 2,250,000 live births, 269,253 (12.0%) were PTBs and 182,960 (8.1%) were LBW. On average, states had approximately seven restrictive abortion policies enacted from 2005 to 2015. Black individuals experienced increased probability of PTB with additional exposure to restrictive abortion policies compared to non-Black individuals. Similarly, those with less than a college degree experienced increased probability of LBW with additional exposure to restrictive abortion policies compared to college graduates. For all analyses, inequities worsened as state environments grew increasingly restrictive. CONCLUSION: Findings demonstrate that Black individuals at all educational levels and those with fewer years of education disproportionately experienced adverse birth outcomes associated with restrictive abortion policies. Restrictive abortion policies may compound existing racial/ethnic, socioeconomic, and intersecting racial/ethnic and socioeconomic perinatal and infant health inequities.

Testing a Tailored Social-Ecological Model for Autism Spectrum Disorders.

OBJECTIVE: To propose a tailored social ecological model for Autism Spectrum Disorders and explore relationships between variables in a large nationally-representative dataset. METHODS: A tailored social-ecological model was developed and examined across variables in the 2016/2017 National Survey of Children's Health. A series of iterative multivariable logistic regressions were performed including individual, family, and community/neighborhood variables. A multivariable logistic regression using state-level fixed effects was performed to understand dynamics related to macro-level policies. RESULTS: In the full model, gender, disability severity, certain types of insurance coverage and household income were significantly related to ASD diagnosis. Females had lower odds of a diagnosis compared to males (aOR: 0.27; CI:0.18-0.41). Children with at least one other moderate/severe disability had odds 7.61 higher (CI:5.36-10.82) of a diagnosis than children without moderate/severe disabilities. Children with public insurance only (aOR:1.66; CI:1.14-2.41) or both private and public insurance coverage (aOR: 2.62; CI:1.6-4.16) had higher odds of a diagnosis compared to children with private insurance only. For those who reported it was "somewhat" or "very often" hard to cover basics with their income, odds of a diagnosis were higher compared to those who reported it was "never" or "hardly ever" hard to cover basics (aOR: 1.676; CI:0.21-2.56). CONCLUSIONS FOR PRACTICE: Patterns of ASD diagnosis are related to individual and family characteristics. There is some evidence that a child's environment has some relationship to reported ASD diagnosis. Professionals should be aware of an individual's environmental factors or context when assessing for ASD.

Contraceptive Use and Pregnancy Outcomes Among Women Enrolled in South Carolina Medicaid Programs.

OBJECTIVE: State medicaid programs provide access to effective contraception for people with lower incomes. This study examined contraception use and pregnancy among reproductive-age women enrolled in the South Carolina Medicaid, by eligibility program and socio-demographic sub-groups. METHODS: A retrospective cohort of women aged 15-45 who were newly eligible for South Carolina Medicaid from 2012 to 2016 was examined. Log-binomial regression and average marginal effects assessed relationships between contraception use and pregnancies ending in live and non-live births. Contraception was categorized as permanent, long acting reversible contraception (LARC), short-acting hormonal contraception (SAC), or no contraceptive claims. Women with family planning or full-benefit medicaid coverage were included. RESULTS: Approximately 11% of women used LARC methods, 41% used SAC methods, and 46% had no evidence of contraceptive claims. Method utilization varied by eligibility program, race/ethnicity and age. The likelihood of pregnancy was lower among SAC users and lowest among LARC users compared to women with no evidence of contraception across all three programs (family planning APR = 0.44; 95% CI 0.41-0.49 and APR = 0.13, 95% CI 0.10-0.17; Low income families APR = 0.82; 95% CI 0.77-0.88 and APR = 0.33, 95% CI 0.28-0.38; Partners for Healthy Children APR = 0.72; 95% CI 0.68-0.77 and APR = 0.35, 95% CI 0.30-0.43, respectively). Non-Hispanic Black and Hispanic teens were less likely to experience a pregnancy than non-Hispanic white teens. CONCLUSIONS FOR PRACTICE: The likelihood of pregnancy was lower among women using SAC methods and markedly lower among women using LARC. Variation in contraceptive use among racial/ethnic groups was noted despite Medicaid coverage. As new policies and initiatives emerge, these findings provide important context for understanding the role of Medicaid programs in reducing financial barriers to contraceptive services and ensuring access to effective contraception, while fostering reproductive health autonomy among women.

Integration of cardiologists with hospitals: Effects on physician compensation and productivity.

BACKGROUND: Hospital-physician vertical integration involving employment of physicians has increased considerably over the last decade. Cardiologists are one group of specialists being increasingly employed by hospitals. Although hospital-physician integration has the potential to produce economic and societal benefits, there is concern that this consolidation may reduce competition and concentrate bargaining power among providers. In addition, hospitals may be motivated to offer cardiologists higher compensation and reduced workloads as an incentive to integrate. PURPOSE: The aim of the study was to determine if there are differences in compensation and clinical productivity, measured by work relative value units (RVUs), for cardiologists as they transition from being independent practitioners to being employed by hospitals. METHODOLOGY/APPROACH: This study was a quantitative, retrospective, longitudinal analysis, comparing the compensation and work RVUs of integrated cardiologists to their compensation and work RVUs as independent cardiologists. Data from the MedAxiom Annual Survey from 2010 to 2014 were used. Participants included 4,830 unique cardiologists that provided 13,642 pooled physician-year observations, with ownership status, compensation, work (RVUs), and other characteristics as variables for analysis. RESULTS: Results from the multivariate regressions indicate that average compensation for cardiologists increases by $129,263.1 (p < .001) when they move from independent to integrated practice. At the same time, physician work RVUs decline by 398.04 (p = .01). CONCLUSION: Our findings support the conjecture that hospitals may be offering higher pay and lower workloads to incentivize cardiologists to integrate. PRACTICE IMPLICATIONS: Although hospitals may have goals of quality improvement and lower costs, such goals may presently be secondary to service line growth and increased market power. There is reason to be cautious about some of the implications of hospital integration of cardiologists.

Hospitals' use of hospitalists: Implications for financial performance.

BACKGROUND: Hospitalists, or physicians specializing in hospital-based practice, have grown significantly since they were first introduced in the United States in the mid-1990s. Prior studies on the impact of hospitalists have focused on costs and length of stay. However, there is dearth of research exploring the relationship between hospitals' use of hospitalists and organizational performance. PURPOSE: Using a national longitudinal sample of acute care hospitals operating in the United States between 2007 and 2014, this study explores the impact of hospitalists staffing intensity on hospitals' financial performance. METHODOLOGY: Data sources for this study included the American Hospital Association Annual Survey, the Area Health Resources File, and the Centers for Medicare & Medicaid Services' costs reports and Case Mix Index files. Data were analyzed using a panel design with facility and year fixed effects regression. RESULTS: Results showed that hospitals that switched from not using hospitalists to using a high hospitalist staffing intensity had both increased patient revenues and higher operating costs per adjusted patient day. However, the higher operating costs from high hospitalist staffing intensity were offset by increased patient revenues, resulting in a marginally significant increase in operating profitability (p < .1). PRACTICE IMPLICATIONS: These findings suggest that the rise in the use of hospitalists may be fueled by financial incentives such as increased revenues and profitability in addition to other drivers of adoption.

Market and organizational factors associated with hospital vertical integration into sub-acute care.

BACKGROUND: Changes in payment models incentivize hospitals to vertically integrate into sub-acute care (SAC) services. Through vertical integration into SAC, hospitals have the potential to reduce the transaction costs associated with moving patients throughout the care continuum and reduce the likelihood that patients will be readmitted. PURPOSE: The purpose of this study is to examine the correlates of hospital vertical integration into SAC. METHODOLOGY/APPROACH: Using panel data of U.S. acute care hospitals (2008-2012), we conducted logit regression models to examine environmental and organizational factors associated with hospital vertical integration. Results are reported as average marginal effects. FINDINGS: Among 3,775 unique hospitals (16,269 hospital-year observations), 25.7% vertically integrated into skilled nursing facilities during at least 1 year of the study period. One measure of complexity, the availability of skilled nursing facilities in a county (ME = -1.780, p < .001), was negatively associated with hospital vertical integration into SAC. Measures of munificence, percentage of the county population eligible for Medicare (ME = 0.018, p < .001) and rural geographic location (ME = 0.069, p < .001), were positively associated with hospital vertical integration into SAC. Dynamism, when measured as the change county population between 2008 and 2011 (ME = 1.19e-06, p < .001), was positively associated with hospital vertical integration into SAC. Organizational resources, when measured as swing beds (ME = 0.069, p < .001), were positively associated with hospital vertical integration into SAC. Organizational resources, when measured as investor owned (ME = -0.052, p < .1) and system affiliation (ME = -0.041, p < .1), were negatively associated with hospital vertical integration into SAC. PRACTICE IMPLICATIONS: Hospital adaption to the changing health care landscape through vertical integration varies across market and organizational conditions. Current Centers for Medicare and Medicaid reimbursement programs do not take these factors into consideration. Vertical integration strategy into SAC may be more appropriate under certain market conditions. Hospital leaders may consider how to best align their organization's SAC strategy with their operating environment.

Red blood cell transfusion therapy for sickle cell patients with frequent painful events.

BACKGROUND: Recurrent pain events or chronic pain are among the most common complications of sickle cell disease. Despite attempts to maximize adherence to and dosing of hydroxyurea, some patients continue to suffer from pain. Our institution developed a program to initiate chronic red blood cell transfusions for one year in patients clinically deemed to have high healthcare utilization from sickle cell pain, despite being prescribed hydroxyurea. PROCEDURE: An institutional review board approved retrospective study to evaluate the health outcomes associated with a one-year red blood cell transfusion protocol in sickle cell patients experiencing recurrent pain events as compared with the health outcomes for these patients in the one year prior to receiving transfusion therapy. We performed a matched-pair analysis using a Wilcoxon signed rank to determine the impact of transfusion therapy on clinic visits, emergency department visits, hospital admissions, hospitalization days, and opioid prescriptions filled. RESULTS: One year of transfusion therapy significantly reduced the number of total emergency department visits for pain (6 vs 2.5 pain visits/year, P = 0.005), mean hospitalizations for pain (3.4 vs 0.9 pain admissions/year), and mean hospital days per year for pain crisis (23.5 vs 4.5, P = 0.0001), as compared with the one year prior to transfusion therapy. We identified no significant difference in opioid prescriptions filled during the year of transfusion therapy. CONCLUSION: Patients with frequent pain episodes may benefit from one year of transfusion therapy.

The Effectiveness of a Comprehensive Wellness Assessment on Medication Adherence in a Medicare Advantage Plan Diabetic Population.

EXECUTIVE SUMMARY: The issue of medication nonadherence has generated significant interest because of its complexity from both cost and outcomes perspectives. Of the 3.2 billion prescriptions written annually in the United States, estimates indicate that half are not taken as prescribed, especially among patients with asymptomatic chronic conditions. The objective of this study was to assess whether a comprehensive wellness assessment (CWA) program helps improve medication adherence for oral diabetic medications, statins, and angiotensin-converting enzyme inhibitors or angiotensin II receptor blockers (ACE/ARBs) in a Medicare Advantage (MA) plan diabetic population. The Centers for Medicare & Medicaid Services includes these medications among its triple-weighted measures.The researchers used a retrospective panel study employing administrative claims data and member month-level enrollment data for members who were newly diagnosed with diabetes since 2010, allowing for up to 5 years of follow-up. The treatment variable of interest was whether the enrollee had undergone a CWA in the 12 months prior to the study. Results for the full sample show that a CWA visit in the prior 12 months is significantly associated with increased adherence to statin medication (incidence rate ratio [IRR]: 1.022, t-test: 2.51) and oral diabetes medication (IRR: 1.032, t-test: 3.00), but it is not significantly associated with adherence to ACE/ARB medication (IRR: 1.009, t-test: 1.09). Results vary considerably in subsamples stratified by dual Medicare and Medicaid eligibility status, presence of certain chronic conditions, and age. CWAs are most beneficial when targeted toward dual-eligible members or members younger than 65. On the basis of these findings, improving medication adherence by targeting CWA visits to certain MA member subcategories may be more cost-effective than using CWAs for the full MA membership.

Contextual factors associated with hospitals' decision to operate freestanding emergency departments.

BACKGROUND: Freestanding emergency departments (FSEDs) are fast growing entities in health care, delivering emergency care outside of hospitals. Hospitals may benefit in several ways by opening FSEDs. PURPOSE: The study used the resource dependence theory as a means to analyze the relationship between market and organizational factors and the likelihood of hospitals to operate FSEDs. METHODOLOGY: All acute care hospitals in 14 states with FSEDs present during the study period from 2002 to 2011. Data on FSEDs were merged with American Hospital Association Annual Survey, Centers for Medicare and Medicaid Services' Cost Reports, and Area Resource File data. The outcome variable consists of whether or not the hospital operates an FSED. Independent variables include per capita income, percent population over age of 65 years, primary care and specialist physicians per capita, urban location, change in the unemployment rate, change in the population, change in poverty level, market competition, total satellite and autonomous FSEDs in the market, Medicare-managed care penetration rate, hospital beds, total margin, and system membership. We used logistic regression analysis with state and year fixed effects. Standard errors in the regression were clustered by hospital. PRINCIPAL FINDINGS: The number of hospitals operating satellite FSEDs increased from 32 (2.33%) in 2002 to 91 (5.76%) hospitals in 2011 among the 14 states included in the study sample. The results support the hypothesis that hospitals located in munificent environments and more competitive environments (presence of other FSEDs) are more likely to operate an FSED. Organizational level factors such as bed size and system membership are associated with a hospital operating an FSED. PRACTICE IMPLICATIONS: The findings may be used by policy makers in developing regulations for hospitals opening FSEDs. Also, study findings of this study may be used by hospitals to make informed decisions when formulating strategies regarding FSEDs.

Myths, presumptions, and facts about obesity.

BACKGROUND: Many beliefs about obesity persist in the absence of supporting scientific evidence (presumptions); some persist despite contradicting evidence (myths). The promulgation of unsupported beliefs may yield poorly informed policy decisions, inaccurate clinical and public health recommendations, and an unproductive allocation of research resources and may divert attention away from useful, evidence-based information. METHODS: Using Internet searches of popular media and scientific literature, we identified, reviewed, and classified obesity-related myths and presumptions. We also examined facts that are well supported by evidence, with an emphasis on those that have practical implications for public health, policy, or clinical recommendations. RESULTS: We identified seven obesity-related myths concerning the effects of small sustained increases in energy intake or expenditure, establishment of realistic goals for weight loss, rapid weight loss, weight-loss readiness, physical-education classes, breast-feeding, and energy expended during sexual activity. We also identified six presumptions about the purported effects of regularly eating breakfast, early childhood experiences, eating fruits and vegetables, weight cycling, snacking, and the built (i.e., human-made) environment. Finally, we identified nine evidence-supported facts that are relevant for the formulation of sound public health, policy, or clinical recommendations. CONCLUSIONS: False and scientifically unsupported beliefs about obesity are pervasive in both scientific literature and the popular press. (Funded by the National Institutes of Health.).

Does electronic health record use improve hospital financial performance? Evidence from panel data.

PURPOSE: The aim of this study was to examine the impact of electronic health record (EHR) adoption on hospital financial performance. METHODOLOGY/APPROACH: We constructed a longitudinal panel using data from the three secondary sources: (a) the 2007-2010 American Hospital Association (AHA) Annual Survey, (b) the 2007-2010 AHA Annual Survey Information Technology Supplement, and (c) the 2007-2011 Medicare Cost Reports from Centers for Medicare and Medicaid Services. Because potential financial benefits attributable to EHR adoption may take some time to accrue, we ran regressions with lags of 1 and 2 years that included hospital and year fixed effects to examine the relationship between the level of EHR adoption and three hospital financial performance measures. FINDINGS: A change in the level of EHR adoption was not associated with changes in operating margin or return on assets within hospitals. However, total margin was significantly improved, after 2 years, in hospitals that moved from no EHR to having a comprehensive EHR in all areas of their hospital (ß = 0.030, p < .034). On the other hand, hospitals that increased their level of EHR adoption but did not achieve hospital-wide comprehensive adoption did not experience changes in any financial performance measures examined. PRACTICE IMPLICATIONS: The improvements in total margin, as opposed to operating margin, are likely due to hospital incentive payments under the Health Information Technology for Economic and Clinical Health Act that are reflected in nonpatient revenues and therefore show up in total margin calculations. Thus, after 2 years of EHR adoption, hospital financial performance is observed to improve based only on meaningful use incentive payments. More research will be needed to determine whether EHR adoption impacts financial performance on a longer time horizon.

The impact of texting bans on motor vehicle crash-related hospitalizations.

We used a panel design and the Nationwide Inpatient Sample from 19 states between 2003 and 2010 to examine the impact of texting bans on crash-related hospitalizations. We conducted conditional negative binomial regressions with state, year, and month fixed effects to examine changes in crash-related hospitalizations in states after the enactment of a texting ban relative to those in states without such bans. Results indicate that texting bans were associated with a 7% reduction in crash-related hospitalizations among all age groups. Texting bans were significantly associated with reductions in hospitalizations among those aged 22 to 64 years and those aged 65 years or older. Marginal reductions were seen among adolescents. States that have not passed strict texting bans should consider doing so.

Weighing the Evidence of Common Beliefs in Obesity Research.

Obesity is a topic on which many views are strongly held in the absence of scientific evidence to support those views, and some views are strongly held despite evidence to contradict those views. We refer to the former as "presumptions" and the latter as "myths." Here, we present nine myths and 10 presumptions surrounding the effects of rapid weight loss; setting realistic goals in weight loss therapy; stage of change or readiness to lose weight; physical education classes; breastfeeding; daily self-weighing; genetic contribution to obesity; the "Freshman 15"; food deserts; regularly eating (versus skipping) breakfast; eating close to bedtime; eating more fruits and vegetables; weight cycling (i.e., yo-yo dieting); snacking; built environment; reducing screen time in childhood obesity; portion size; participation in family mealtime; and drinking water as a means of weight loss. For each of these, we describe the belief and present evidence that the belief is widely held or stated, reasons to support the conjecture that the belief might be true, evidence to directly support or refute the belief, and findings from randomized controlled trials, if available. We conclude with a discussion of the implications of these determinations, conjecture on why so many myths and presumptions exist, and suggestions for limiting the spread of these and other unsubstantiated beliefs about the obesity domain.
