Project description:BACKGROUND:The economic shock of 2008-2009 provided an opportunity to study the robustness of observed statistical associations between unemployment and problematic substance use. METHODS:Data from 405,000 non-institutionalized adult participants in the 2002 to 2010 U.S. National Survey on Drug Use and Health were used to compare substance outcomes among unemployed and employed persons. Association of unemployment with substance outcomes was examined for the years 2002-2004, 2005-2007, 2008, and 2009-2010, corresponding to periods prior to and after the economic downturn of 2008. Multivariate logistic regression models adjusted for age, sex, race/ethnicity, education, urban/rural residence, current DSM-IV Major Depression, and local county unemployment rates. RESULTS:Higher rates of past month tobacco and illicit drug use, heavy alcohol use, and past-year drug or alcohol abuse/dependence were found among the unemployed. Markedly increased unemployment in 2009-2010 did not moderate the association between substance outcomes and employment. This association was not confounded by sex, age group, or race/ethnicity for tobacco and illicit drugs, although it varied for alcohol outcomes among 18-25 year-olds. Results based on retrospective data regarding marijuana use in the period prior to unemployment suggest its use was associated with future job loss. CONCLUSIONS:Employment status was strongly and robustly associated with problematic use of substances. Prevention and treatment interventions are warranted for a group whose employment and resulting insurance status may impair access to much needed health care.

Project description:Background & aimsIt is not clear whether evidence-based recommendations for inpatient care of patients with cirrhosis are implemented widely or are effective in the community. We investigated changes in inpatient outcomes and associated features over time.MethodsBy using the Healthcare Cost and Utilization Project, National Inpatient Sample, we analyzed 781,515 hospitalizations of patients with cirrhosis from 2002 through 2010. We compared data with those from equal numbers of hospitalizations of patients without cirrhosis and patients with congestive heart failure (CHF), matched for age, sex, and year of discharge. The primary outcome was a change in discharge status over time. Factors associated with outcomes were analyzed by Poisson modeling.ResultsThe mortality of patients with and without cirrhosis, and patients with CHF, decreased over time. The absolute decrease was significantly greater for patients with cirrhosis (from 9.1% to 5.4%) than for patients without cirrhosis (from 2.6% to 2.1%) or patients with CHF (from 2.5% to 1.4%) (P < .01). However, relative decreases were similar for patients with cirrhosis (41%) and patients with CHF (44%). For patients with cirrhosis, the independent mortality risk ratio decreased steadily to 0.50 by 2010 (95% confidence interval, 0.48-0.52), despite patients' increasing age and comorbidities. Hepatorenal syndrome, hepatocellular carcinoma, variceal bleeding, and spontaneous bacterial peritonitis were associated with a higher mortality rate, but the independent mortality risks for each decreased steadily. Sepsis was associated strongly with increased mortality, and the risk increased over time.ConclusionsAmong patients with cirrhosis in the United States, inpatient mortality decreased steadily from 2002 through 2010, despite increases in patient age and medical complexity. Improvements in cirrhosis care may have contributed to increases in patient survival beyond those attributable to general improvements in inpatient care. Further improvements might require an increased use of proven therapies and the development of new treatments-particularly for sepsis.

Project description:While population growth has been consistently tied to decreasing racial segregation at the metropolitan level in the United States, little work has been done to relate small-scale changes in population size to integration. We address this question through a novel technique that tracks population changes by race and ethnicity for comparable geographies in both 2000 and 2010. Using the Theil Index, we analyze the fifty most populous Metropolitan Statistical Areas in 2010 for changes in multigroup segregation. We classify local areas by their net population change between 2000 and 2010 using a novel unit of analysis based on aggregating census blocks. We find strong evidence that growing parts of rapidly growing metropolitan areas of the United States are crucial to understanding regional differences in segregation that have emerged in past decades. Multigroup segregation declined the most in growing parts of growing metropolitan areas. Comparatively, growing parts of shrinking or stagnant metropolitan areas were less diverse and had smaller declines in segregation. We also find that local areas with shrinking populations had disproportionately high minority representation in 2000 before population loss took place. We conclude that the regional context of population growth or decline has important consequences for the residential mixing of racial groups.

Project description:This study examines proximate sources of change in first-marriage trajectories in the United States between 1960 and 2010. This was a period of tremendous social change: divorce became more common, people started marrying later or not marrying at all, innovations in medicine and changes in social and behavioral factors led to reduced mortality, inequality grew stronger and was reflected by more intense assortative mating, and the country underwent a massive educational expansion. Each of these factors influenced the formation and dissolution of first marriages over this period. This article extends the multiple-decrement life table to incorporate heterogeneity and assortative mating, which allows the quantification of how changes in the incidence of marriage, divorce, and mortality, along with changes in educational attainment and assortative mating, have shaped trends in first-marriage trajectories. The model is used to prove that stronger educational assortative mating leads to longer average durations of first marriage. Using data from multiple sources and this model, this study shows that although the incidence of divorce was the primary determinant of changes in first-marriage trajectories between 1960 and 1980, it has played a relatively smaller role in driving change in marital trajectories between 1980 and 2010. Instead, factors such as later age at first marriage, educational expansion, declining mortality, narrowing sex differences in mortality, and more intense educational assortative mating have been the major drivers of changes in first-marriage trajectories since 1980.

Project description:BackgroundViridans group streptococci (VGS) are typically part of the commensal flora but can also cause severe invasive diseases such as infective endocarditis. There are limited data available showing antibiotic susceptibility over time for VGS.ObjectivesTo evaluate antibiotic susceptibility trends in VGS over time.MethodsIn vitro susceptibility patterns for 33 antibiotics were examined for Streptococcus mitis, Streptococcus oralis, and non-speciated VGS isolates from patients in Veterans Affairs (VA) Medical Centers in the United States between 2010 and 2020. Susceptibility determinations were made by the individual clinical microbiology laboratories and data were retrospectively collected from the VA Corporate Data Warehouse. Susceptibility trends were analysed using Poisson regression.ResultsA total of 14 981 VGS isolates were included of which 19.5%, 0.7% and 79.8% were S. mitis, S. oralis and non-speciated VGS isolates, respectively. Cumulative susceptibility rates across all years were similar between species for ceftriaxone (range: 96.0% to 100%), clindamycin (81.3% to 84.5%), and vancomycin (99.7% to 100%). For penicillin, susceptibility rates were 71.0%, 80.9% and 86.3% for S. mitis, S. oralis and non-speciated isolates, respectively. From 2010 to 2020, susceptibility of non-speciated VGS isolates decreased for erythromycin (P = 0.0674), penicillin (P = 0.0835), and tetracycline (P = 0.0994); though the decrease was only significant for clindamycin (P = 0.0033). For S. mitis, a significant susceptibility rate decrease was observed for erythromycin (P = 0.0112).ConclusionsSusceptibility rates for some clinically relevant antibiotics declined between 2010 and 2020. This worrisome trend highlights the need to improve antimicrobial stewardship efforts to limit unnecessary antibiotic use and preserve empirical treatment options.

Project description:BackgroundAlthough prior studies of inpatient maternal mortality in the United States provide data on the overall rate and trend in inpatient maternal mortality, there are no published reports of maternal mortality data stratified by timing of its occurrence across the pregnancy continuum (antepartum, intrapartum, and postpartum).ObjectiveThe study objective was to determine whether the maternal mortality rate, trends over time, self-reported race/ethnicity, and associated factors vary based on the timing of the occurrence of death during pregnancy.MethodsWe conducted a cross-sectional analysis of the Nationwide Inpatient Sample database to identify pregnancy-related inpatient stays stratified by timing. Among women in the sample, we determined in-hospital mortality and used International Classification of Diseases, Ninth Revision, Clinical Modification codes to identify comorbidities and behavioral characteristics associated with mortality, including alcohol, drug, and tobacco use. Joinpoint regression was used to calculate rates and trends of in-hospital maternal mortality.ResultsDuring the study period, there were 7,411 inpatient maternal mortalities among an estimated 58,742,179 hospitalizations of women 15-49 years of age. In-hospital maternal mortality rate stratified by race showed that African Americans died at significantly higher rates during antepartum, intrapartum, and postpartum periods compared to hospitalizations for Whites or Hispanics during the same time period. Although the postpartum hospitalization represents only 2% of pregnancy-related hospitalizations among women aged 15-49 years, hospitalization during this time period accounted for 27.2% of all maternal deaths during pregnancy-related hospitalization.DiscussionMost in-hospital maternal mortalities occur after hospital discharge from child birth (postpartum period). Yet, the postpartum period continues to be the time period with the least maternal healthcare surveillance in the pregnancy continuum. African American women experience three times more in-hospital mortality when compared to their White counterparts.

Project description:Published reports suggest efforts designed to prevent the occurrence of harmful algal blooms and hypoxia by reducing non-point and point source phosphorus (P) pollution are not delivering water quality improvements in many areas. Part of the uncertainty in evaluating watershed responses to management practices is the lack of standardized estimates of phosphorus inputs and outputs. To assess P trends across the conterminous United States, we compiled an inventory using publicly available datasets of agricultural P fluxes, atmospheric P deposition, human P demand and waste, and point source discharges for 2002, 2007, and 2012 at the scale of the 8-digit Hydrologic Unit Code subbasin (~1,800 km2). Estimates of agricultural legacy P surplus accumulated from 1945 to 2001 were also developed. Fertilizer and manure inputs were found to exceed crop removal rates by up to 50% in many agricultural regions. This excess in inputs has led to the continued accumulation of legacy P in agricultural lands. Atmospheric P deposition increased throughout the Rockies, potentially contributing to reported increases in surface water P concentrations in undisturbed watersheds. In some urban areas, P fluxes associated with human waste and non-farm fertilizer use has declined despite population growth, likely due, in part, to various sales bans on P-containing detergents and fertilizers. Although regions and individual subbasins have different contemporary and legacy P sources, a standardized method of accounting for large and small fluxes and ready to use inventory numbers provide essential infromation to coordinate targeted interventions to reduce P concentrations in the nation's waters.

Project description:Pulmonary hypertension (PH) is an uncommon but progressive condition, and much of what we know about it comes from specialized disease registries. With expanding research into the diagnosis and treatment of PH, it is important to provide updated surveillance on the impact of this disease on hospitalizations and mortality. This study, which builds on previous PH surveillance of mortality and hospitalization, analyzed mortality data from the National Vital Statistics System and data from the National Hospital Discharge Survey between 2001 and 2010. PH deaths were identified using International Classification of Diseases, Tenth Revision codes I27.0, I27.2, I27.8, or I27.9 as any contributing cause of death on the death certificate. Hospital discharges associated with PH were identified using International Classification of Diseases, Ninth Revision, Clinical Modification codes 416.0, 416.8, or 416.9 as one of up to seven listed medical diagnoses. The decline in death rates associated with PH among men from 1980 to 2005 has reversed and now shows a significant increasing trend. Similarly, the death rates for women with PH have continued to increase significantly during the past decade. PH-associated mortality rates for those aged 85 years and older have accelerated compared with rates for younger age groups. There have been significant declines in PH-associated mortality rates for those with pulmonary embolism and emphysema. Rates of hospitalization for PH have increased significantly for both men and women during the past decade; for those aged 85 years and older, hospitalization rates have nearly doubled. Continued surveillance helps us understand and address the evolving trends in hospitalization and mortality associated with PH and PH-associated conditions, especially regarding sex, age, and race/ethnicity disparities.

Project description:BackgroundBlastomycosis is an environmentally acquired fungal disease that can cause severe illness, with approximately 65% of reported cases requiring hospitalization. Recent trends in blastomycosis-associated hospitalizations in the United States have not been described.MethodsWe analyzed hospital discharge data from the Healthcare Cost and Utilization Project (HCUP) National (Nationwide) Inpatient Sample. We calculated hospitalization rates per 100,000 population using U.S. census data and examined factors associated with in-hospital mortality.ResultsAn estimated 11,776 blastomycosis-associated hospitalizations occurred during 2010-2020 (average yearly rate 0.3 per 100,000 persons), with no apparent temporal trend. Rates were consistently highest among persons ≥65 years old and males. In-hospital death occurred in 7.9% and approximately doubled from 3.9% in 2010 to 8.5% in 2020. Older age, chronic obstructive pulmonary disease, and malignancy were associated with mortality.ConclusionsBlastomycosis-associated hospitalizations can result in poor outcomes, underscoring the continued need for attention to early detection and treatment of blastomycosis and monitoring of disease trends.

Project description:BACKGROUND:In 2015 there were 36,252 firearm-related deaths and 84,997 nonfatal injuries in the United States. The longitudinal burden of these injuries through readmissions is currently underestimated. We aimed to determine the 6-month readmission risk and hospital costs for patients injured by firearms. METHODS:We used the Nationwide Readmission Database 2010-2015 to assess the frequency of readmissions at 6 months, and hospital costs associated with readmissions for patients with firearm-related injuries. We produced nationally representative estimates of readmission risks and costs. RESULTS:Of patients discharged following a firearm injury, 15.6% were readmitted within 6 months. The average annual cost of inpatient hospitalizations for firearm injury was over $911 million, 9.5% of which was due to readmissions. Medicare and Medicaid covered 45.2% of total costs for the 5 years, and uninsured patients were responsible for 20.1%. CONCLUSIONS:From 2010-2015, the average total cost of hospitalization for firearm injuries per patient was $32,700, almost 10% of which was due to readmissions within 6 months. Government insurance programs and the uninsured shouldered most of this.
