The epidemiology of firework-related injuries in the United States: 2000-2010

INTRODUCTION The purpose of this study is to examine the epidemiology of firework-related injuries among an emergency department (ED) nationally representative population of the United States for the years 2000-2010, including whether the type of firework causing the injury is differential by patient demographics and whether the severity of injury is associated with the firework type. METHODS The data analysed in this study was collected from the Consumer Product Safety Commissions (CPSCs) National Electronic Injury Surveillance System (NEISS). RESULTS A total of 2812 injuries represented an estimated 97,562 firework-related injuries treated in emergency departments within the United States from 2000 to 2010. The incidence generally decreased over time. With respect to age, the rate was higher for children, with the highest rates being observed for 10-19 year olds (7.28 per 100,000 persons) and 0-9 year olds (5.45 per 100,000 persons). The injury rate was nearly three times higher for males compared to the female counterparts (4.48 vs. 1.57 per 100,000 persons). Females were less likely than males to severely injure themselves with all types of fireworks besides sparklers/novelty devices (OR 1.08, CI 0.26-4.38). DISCUSSION The results from this suggest that firework-related injuries have decreased by nearly 30% over the 11-year period between 2000 and 2010. Moreover, there has been a decreasing trend in the type of firework causing injury for every firework type excluding the unspecified firework type. However, adolescents of 10-19 years old had the highest rate of injury for fireworks over the 11-year period. In addition odds of injury are differential by firework type. CONCLUSION Understanding the specific types of fireworks may lead to better preventative methods and regulations. Moreover, preventative methods should be taken to reduce the rate of firework-related injuries among U.S. youths [1], and possibly more regulations and enforcement of laws geared towards prohibiting novice use of fireworks.

Black-white racial disparities in sepsis: a prospective analysis of the REasons for Geographic And Racial Differences in Stroke (REGARDS) cohort.

IntroductionSepsis is a major public health problem. Prior studies using hospital-based data describe higher rates of sepsis among black than whites participants. We sought to characterize racial differences in incident sepsis in a large cohort of adult community-dwelling adults.MethodsWe analyzed data on 29,690 participants from the Reasons for Geographic and Racial Differences in Stroke (REGARDS) cohort. We determined the associations between race and first-infection and first-sepsis events, adjusted for participant sociodemographics, health behaviors, chronic medical conditions and biomarkers. We also determined the association between race and first-sepsis events limited to first-infection events. We contrasted participant characteristics and hospital course between black and white sepsis hospitalizations.ResultsAmong eligible REGARDS participants there were 12,216 (41.1 %) black and 17,474 (58.9 %) white participants. There were 2,600 first-infection events; the incidence of first-infection events was lower for black participants than for white participants (12.10 vs. 15.76 per 1,000 person-years; adjusted HR 0.65; 95 % CI, 0.59-0.71). There were 1,526 first-sepsis events; the incidence of first-sepsis events was lower for black participants than for white participants (6.93 vs. 9.10 per 1,000 person-years, adjusted HR 0.64; 95 % CI, 0.57-0.72). When limited to first-infection events, the odds of sepsis were similar between black and white participants (adjusted OR 1.01; 95 % CI, 0.84-1.21). Among first-sepsis events, black participants were more likely to be diagnosed with severe sepsis (76.9 % vs. 71.5 %).ConclusionIn the REGARDS cohort, black participants were less likely than white participants to experience infection and sepsis events. Further efforts should focus on elucidating the underlying reasons for these observations, which are in contrast to existing literature.

Defining Sepsis Mortality Clusters in the United States

Objectives: In the United States, sepsis is a major public health problem accounting for over 200,000 annual deaths. The aims of this study were to identify U.S. counties with high sepsis mortality and to assess the community characteristics associated with increased sepsis mortality. Design: We performed a descriptive analysis of 2003 through 2012 Compressed Mortality File data. We defined sepsis deaths as deaths associated with an infection, classified according to the International Classification of Diseases, 10th Version. Setting: Three thousand one hundred and eight counties in the contiguous U.S. counties, excluding Hawaii and Alaska. Measurements and Main Results: Using geospatial autocorrelation methods, we defined county-level sepsis mortality as strongly clustered, moderately clustered, and nonclustered. We approximated the mean crude, age-adjusted, and community-adjusted sepsis mortality rates nationally and for clustering groups. We contrasted demographic and community characteristics between clustering groups. We performed logistic regression for the association between strongly clustered counties and community characteristics. Among 3,108 U.S. counties, the age-adjusted sepsis mortality rate was 59.6 deaths per 100,000 persons (95% CI, 58.9–60.4). Sepsis mortality was higher in the Southern U.S. and clustered in three major regions: Mississippi Valley, Middle Georgia, and Central Appalachia. Among 161 (5.2%) strongly clustered counties, age-adjusted sepsis mortality was 93.1 deaths per 100,000 persons (95% CI, 90.5–95.7). Strongly clustered sepsis counties were more likely to be located in the south (92.6%; p < 0.001), exhibit lower education, higher impoverished population, without medical insurance, higher medically uninsured rates, and had higher unemployment rates (p < 0.001). Conclusions: Sepsis mortality is higher in the Southern United States, with three regional clusters: “Mississippi Valley,” “Middle Georgia,” and “Central Appalachia”: Regions of high sepsis mortality are characterized by lower education, income, employment, and insurance coverage.

Epidemiology of High-Heel Shoe Injuries in U.S. Women: 2002 to 2012

The purpose of the present study was to investigate the epidemiology of high-heel-related injuries among a nationally representative population of women in the United States and to analyze the demographic differences within this group. The data used in the present study were collected from the Consumer Product Safety Commissions National Electronic Injury Surveillance System. A total of 3294 injuries, representing an estimated 123,355 high-heel-related injuries, were treated in emergency departments within the United States from 2002 to 2012. The overall rate of high-heel-related injuries for the study was 7.32 per 100,000 females (95% confidence interval 7.08 to 7.56). The injury rate was greatest for young adult females, with the greatest rates observed for those aged 20 to 29 years (18.38 per 100,000 females) and those aged 30 to 39 years (11.07 per 100,000 females). The results from the present study suggest that high-heel-related injuries have nearly doubled during the 11-year period from 2002 to 2012. Injuries from high heels are differential by body region, with most injuries occurring as sprains and strains to the foot and ankle. Although high heels might be stylish, from a health standpoint, it could be worthwhile for females and those interested in wearing high heels to understand the risks of wearing high-heeled shoes and the potential harm that precarious activities in high-heeled shoes can cause. The results of the present study can be used in the development of a prospective cohort study to investigate the risk of injury from high-heeled shoes, accounting for the exposure time and studying differences in demographics (e.g., age and race).

Disparities in the prevalence of comorbidities among US adults by state Medicaid expansion status.

INTRODUCTION About 92% of US older adults have at least one chronic disease or medical condition and 77% have at least two. Low-income and uninsured adults in particular experience a higher burden of comorbidities, and the Medicaid expansion provision of the Affordable Care Act was designed to improve access to healthcare in this population group. However, a significant number of US states have declined expansion. The purpose of this study is to determine the distribution of low-income and uninsured adults in expanded versus non-expanded states, and evaluate the prevalence of comorbidities in both groups. METHODS Data from the 2013 Behavioral Risk Factor Surveillance System (BRFSS) dataset was analyzed, and Medicaid expansion status was assessed from the Center for Medicare and Medicaid Services report on State Medicaid and CHIP Income Eligibility Standards. Next, age adjusted mean number of comorbidities between expanded and non-expanded states was compared, with adjustment for socio-demographic differences. RESULTS Expanded states had a higher proportion of adults with income of at least

Risk of Acute Coronary Heart Disease After Sepsis Hospitalization in the REasons for Geographic and Racial Differences in Stroke (REGARDS) Cohort

50,000 per year (39.6% vs. 35.5%, p<0.01) and a lower proportion of individuals with no health insurance coverage (15.2% vs. 20.3%, p<0.01) compared with non-expanded states. Among the uninsured, there was a higher proportion of obese (31.6% vs. 26.9%, p<001), and higher average number of comorbidities (1.62 vs. 1.52, p<0.01) in non-expanded states compared to expanded states. Overall, the prevalence of comorbidities was higher among BRFSS participants in states that did not expand Medicaid compared with those in expanded states. CONCLUSION States without Medicaid expansion have a greater proportion of poor, uninsured adults with more chronic diseases and conditions.

Association of baseline steroid use with long-term rates of infection and sepsis in the REGARDS cohort

Background Sepsis is associated with long-term health consequences. We sought to determine the long-term risks of acute and fatal coronary heart disease (CHD) events after sepsis hospitalizations among community-dwelling adults. Methods We analyzed data from 30329 participants in the population-based REasons for Geographic And Racial Differences in Stroke (REGARDS) cohort. Sepsis events included hospitalizations for a serious infection with ≥2 systemic inflammatory response syndrome criteria. Acute CHD events included myocardial infarctions (MIs; nonfatal and fatal) and acute CHD deaths. Fatal CHD included deaths ≤28 days of an acute MI and acute CHD deaths. We age- and time-matched each sepsis participant with 5 nonsepsis participants. We assessed the associations between sepsis hospitalizations and future acute and fatal CHD events using Cox regression, Grays model, and competing risks analysis, adjusting for comorbidities. Results The matched cohort contained 1070 sepsis and 5350 nonsepsis participants. Risk of acute CHD was higher for sepsis than nonsepsis controls after adjusting for sex, race, education, income, region, tobacco use, and select chronic medical conditions (0-1 year adjusted hazard ratio [HR], 4.38 [95% confidence interval (CI), 2.03-9.45]; 1-4 years, 1.78 [1.09-2.88]; and 4+ years, 1.18 [0.52-2.67]). Risk of fatal CHD was similarly higher for sepsis than nonsepsis individuals (0-1 year adjusted HR, 3.12 [95% CI, 1.35-7.23]; 1-4 years, 3.29 [1.89-5.74]; and 4+ years HR, 1.15 [0.34-3.94]). Conclusions The long-term risks of acute and fatal CHD are elevated after sepsis hospitalization. Management of acute CHD risk may be important for individuals surviving a sepsis event.

Data on burden of comorbidities in the united states and medicaid expansion status.

BackgroundPrior studies associate steroid use with infection risk but were limited to select populations and short follow-up periods. The association of steroid use with long-term risk of community-acquired infections is unknown. We sought to determine the association of steroid risk with long-term risks of community- acquired infections and sepsis.MethodsWe used data on 30,239 adults aged ≥ 45 years old from the Reasons for Geographic and Racial Differences in Stroke (REGARDS) cohort. The primary exposure was oral or injectable steroid use, determined from medication inventory obtained at baseline in-home visit. The primary outcome was time to first infection event during 2003–2012, determined through adjudicated review of hospital records. We determined associations between baseline steroid use and first infection hospitalization events using Cox proportional hazards models, adjusting for demographics, health behaviors, chronic medical conditions, and medication adherence. Among the first infection hospitalization events, we also determined the association between baseline steroid use and sepsis.ResultsSteroid use was reported in 2.24% (n = 677) of the study population. There were 2593 incident infection events during the 10-year follow-up period. Infection incidence rates were higher for steroid than non-steroid users (37.99 vs. 13.79 per 1000 person-years). Steroid use was independently associated with increased risk of infection (adjusted HR 2.10, 95% CI: 1.73–2.56). Among first-infection events, steroid use was associated with increased odds of sepsis (adjusted OR 2.11, 95% CI: 1.33–3.36). The associations persisted in propensity matched analyses as well as models stratified by propensity score and medication adherence.ConclusionsIn this population-based cohort study, baseline steroid use was associated with increased long-term risks of community-acquired infections and sepsis.

A Prospective Study of Obesity, Metabolic Health, and Cancer Mortality: Metabolically Healthy Obesity and Cancer

The high prevalence of comorbidities among US adults is a major public health problem. However, there is limited data on the geographic distribution of comorbidities. In addition, recent changes to health insurance programs in the US through the Affordable Care Act, and the Medicaid expansion program specifically, has the potential to significantly improve the prevention and management of comorbid conditions in the US. In a recent analysis, we examined disparities in the burden of comorbidities among US adults by state Medicaid expansion status, (Akinyemiju et al., 2016) [1]. Here, we provide additional data showing the state level mean number of comorbidities in all 50 US states for African–Americans and whites, stratified by Medicaid expansion status. In addition, we provide a map of the US states showing the geographic distribution of comorbidities and stratified by race/ethnicity and gender.
