Project description:IntroductionDespite guidance towards minimally invasive, outpatient procedures for endometriosis, many patients nonetheless receive inpatient care. Our objective was to assess trends in patient and hospital characteristics, surgical complications and hospital charges for women with an endometriosis-related inpatient admission in the United States.MethodsWe conducted a pooled cross-sectional analysis of Healthcare Cost and Utilization Project Nationwide Inpatient Sample data. Visits were stratified into three time-period-defined cohorts (2006-2007, 2010-2011, and 2014 through the first three quarters of 2015). Visits were included if the patient was aged 18-49 years and the primary diagnosis code was for endometriosis (International Classification of Diseases, 9th Revision code 617.xx). We evaluated counts of inpatient admissions and rates of patient and hospital characteristics.ResultsThe number of inpatient admissions with a primary diagnosis code for endometriosis decreased by 72.8% from 2006 to 2015. At the same time, among those admitted for inpatient care for endometriosis, the proportions who had Medicaid insurance and multiple documented comorbidities increased. From 2006 to 2015, mean total hospital charges increased by 75% to $39,662 in 2015 US dollars, although average length of stay increased by <1 day.ConclusionsThe number of inpatient admissions with a primary diagnosis of endometriosis decreased over the past decade, while surgical complications and associated hospital charges increased. The share of patients with multiple comorbidities increased and an increasing proportion of inpatient endometriosis admissions were covered by Medicaid and occurred at urban teaching hospitals. These findings suggest a demographic shift in patients receiving inpatient care for endometriosis towards more complex, vulnerable patients.

Project description:Blood transfusions are among the most common therapeutic procedures performed in hospitalized patients. This study evaluates contemporary national trends in red blood cell (RBC), plasma, platelet, and cryoprecipitate transfusions. National Inpatient Sample, the largest all-payer inpatient database representing 94% to 97% of the US population, was evaluated from the fourth quarter (Q4) of 2015 through 2018. Quarterly trends for the percentage of hospitalizations with a transfusion procedure were separately examined for each blood product using log binomial regression and reported as quarterly percent change (QPC). The percentage of hospitalizations with an RBC transfusion decreased from 4.22% (2015Q4) to 3.79% (2018Q4) (QPC = -0.72; 95% confidence interval [CI], -1.26 to -0.19; Ptrend = .008). Although plasma transfusions also decreased, QPC = -1.33 (95% CI, -2.00 to -0.65; Ptrend < .001), platelet transfusions remained stable QPC = -0.13 (95% CI, -0.99 to 0.73; Ptrend = .766). In contrast, hospitalizations with cryoprecipitate utilization significantly increased QPC = 2.01 (95% CI, 0.57 to 3.44; Ptrend = .006). Significant quarterly reductions in RBC transfusions were also seen among many, but not all, strata of sex, race/ethnicity, patient risk severity, and admission type (elective vs nonelective). Despite significant declines in RBC transfusions among older adults, there were no significant changes among pediatric age-group (<18 years) and those 18 to 49 years. The decline in RBC and plasma transfusions suggests steady incorporation of robust evidence base showing safety of restrictive transfusions. Increased cryoprecipitate use may be reflective of wider adoption of hypofibrinogenemia management and hemostasis testing for coagulopathic patients.

Project description:Background and objectivesLarge-scale, contemporary studies exploring glomerular disease epidemiology in the United States are lacking. We aimed to determine 30-year temporal and demographic trends in renal biopsy glomerular disease diagnosis frequencies in the southeastern United States.Design, setting, participants, & measurementsIn this cross-sectional, observational study, we identified all patients with a native kidney biopsy specimen showing one of 18 widely recognized glomerular disease diagnoses referred to the University of North Carolina Chapel Hill Division of Nephropathology between 1986 and 2015. Biopsy era (1986-1995, 1996-2005, and 2006-2015) and demographics (age, sex, and race) were our primary and secondary predictors, respectively, and the relative frequency of each glomerular disease diagnosis was our primary outcome.ResultsAmong 21,374 patients (mean age =48.3±18.3 years old; 50.8% men; 56.8% white; 38.3% black; 2.8% Latino; 1.4% Asian; 0.8% other), the frequency of diabetic glomerulosclerosis in renal biopsy specimens increased dramatically over the three decades (5.5%, 11.4%, and 19.1% of diagnoses, respectively; P for trend <0.001). The frequency of FSGS initially increased but then declined (22.6%, 27.2%, and 24.7%, respectively; P for trend =0.64). The frequencies of other common glomerular disease subtypes remained stable (IgA nephropathy and ANCA/pauci-immune GN) or declined (minimal change disease, membranous nephropathy, membranoproliferative GN, and lupus nephritis). These temporal trends were largely preserved within all demographic subgroups, although cross-sectional frequency distributions differed according to age, sex, and race.ConclusionsWe identified significant changes in relative renal biopsy frequencies of many glomerular disease subtypes over three decades. Temporal trends were consistently observed within all major demographic groups, although relative predominance of individual glomerular disease subtypes differed according to patient age, sex, and race. We propose that exploration of behavioral and environmental exposures that likely underlie these findings should be the focus of future hypothesis-driven research.

Project description:OBJECTIVE:Despite the rising toll of drug poisoning deaths in the United States, the extent of the problem among adolescents and young adults ages 15-24 years has received relatively little attention. We examined sociodemographic characteristics and state trends in drug poisoning deaths among adolescents and young adults from 2006 to 2015 and estimated the costs of drug poisoning mortality in this population. METHOD:We used the National Vital Statistics System's Multiple Cause of Death files from 2006 to 2015. We analyzed trends using Joinpoint regression analysis and calculated total costs of drug poisoning deaths, including medical costs, work loss costs, and quality of life loss, based on widely used cost estimates. RESULTS:Drug poisoning death rates (per 100,000 population) in adolescents and young adults increased from 8.1 in 2006 to 9.7 in 2015. The rates increased significantly for Whites (1.7% per year) and Asian/Pacific Islanders (4.3% per year) from 2006 to 2015 and for Blacks (11.8% per year) from 2009 to 2015. By U.S. region, the rates increased significantly in the Midwest (4.4% per year) from 2006 to 2015 and in the Northeast (11.0% per year) from 2009 to 2015. Trends varied by age group, intent for drug poisoning, drug category (i.e., opioids, pharmaceutical drugs excluding opioids, illicit drugs excluding opioids, and unspecified drugs), urbanization level, and state. The estimated costs of drug poisoning deaths among adolescents and young adults totaled approximately $35 billion in 2015. CONCLUSIONS:Trends in drug poisoning deaths and estimated costs inform state-specific prevention and intervention efforts.

Project description:ObjectivesThis study documents trends in risk-adjusted quality and cost for a variety of inpatient surgical procedures among Medicare beneficiaries from 2002 through 2015, which can provide valuable insight on future strategies to improve public health and health care.MethodsWe focused on 11 classes of inpatient surgery, defined by the Agency for Health Research and Quality's (AHRQ's) Clinical Classification System. The surgical classes studied included a wide range of surgeries, including tracheostomy, heart valve procedures, colorectal resection, and wound debridement, among others. For each surgical class, we assessed trends in treatment costs and quality outcomes, as defined by 30-day survival without unplanned readmissions, among Medicare beneficiaries receiving these procedures during hospital stays. Quality and costs were adjusted for patient severity based on demographics, comorbidities, and community context. We also explored surgical innovations of these 11 classes of inpatient surgery from 2002-2015.ResultsWe found significant improvements in quality for 7 surgical classes, ranging from 0.08% (percutaneous transluminal coronary angioplasty) to 0.74% (heart valve procedures) per year. Changes in cost varied by surgery, the significant decrease in cost ranged from -2.59% (tracheostomy) to -0.34% (colorectal resection) per year. Treatment innovation occurred with respect to surgical procedures utilized for heart valve procedures and colorectal resection, which may be associated with the decrease in surgical cost.ConclusionsOur results suggest that there was significant quality improvement for 7 surgery categories over the 14-year study period. Costs decreased significantly for 6 surgery categories, and increased significantly for 3 other categories.

Project description:ObjectiveTo report U.S. national population-based rates and trends in diabetic ketoacidosis (DKA) and hyperglycemic hyperosmolar state (HHS) among adults, in both the emergency department (ED) and inpatient settings.Research design and methodsWe analyzed data from 1 January 2006 through 30 September 2015 from the Nationwide Emergency Department Sample and National Inpatient Sample to characterize ED visits and inpatient admissions with DKA and HHS. We used corresponding year cross-sectional survey data from the National Health Interview Survey to estimate the number of adults ≥18 years with diagnosed diabetes to calculate population-based rates for DKA and HHS in both ED and inpatient settings. Linear trends from 2009 to 2015 were assessed using Joinpoint software.ResultsIn 2014, there were a total of 184,255 and 27,532 events for DKA and HHS, respectively. The majority of DKA events occurred in young adults aged 18-44 years (61.7%) and in adults with type 1 diabetes (70.6%), while HHS events were more prominent in middle-aged adults 45-64 years (47.5%) and in adults with type 2 diabetes (88.1%). Approximately 40% of the hyperglycemic events were in lower-income populations. Overall, event rates for DKA significantly increased from 2009 to 2015 in both ED (annual percentage change [APC] 13.5%) and inpatient settings (APC 8.3%). A similar trend was seen for HHS (APC 16.5% in ED and 6.3% in inpatient). The increase was in all age-groups and in both men and women.ConclusionsCauses of increased rates of hyperglycemic events are unknown. More detailed data are needed to investigate the etiology and determine prevention strategies.

Project description:Infective Endocarditis (IE) is associated with high mortality and morbidity. The data on contemporary trends and health care utilization remain scarce for IE. Consequently, we used the National Inpatient Sample database from 2002 to 2016 to study burden of IE. Risk-adjusted rates were calculated using an Analysis of Covariance with the Generalized Linear Model. Trends were assessed with linear regression and Pearson's Chi-square modeling, where appropriate. Binomial logistic regression was used for computing predictors of in-hospital mortality. We identified 523,432 hospitalizations for native valve IE. Risk-adjusted mortality decreased from 16.7% in 2002 to 9.7% in 2016 (p <0.01). The risk-adjusted length of stay decreased from 17.4 days in 2002 to 13.4 days in 2016 (p <0.01). Mean cost of stay adjusted for risk factors and inflation increased from 112,702$ in 2002 to 164,767$ in 2016 (p <0.01). Valve replacement increased from 10.2% in 2002 in to 13.4% in 2016, (p <0.01). Independent predictors of mortality included age (OR, 1.02 [1.02 to 1.020], p <0.01), female gender (OR, 1.07 [1.05 to 1.09], p <0.01), Blacks (OR, 1.28 [1.24 to 1.31], p <0.01), Hispanics (OR, 1.15 [1.11 to 1.19], p <0.01) and patients with co-morbid conditions like congestive heart failure (OR, 1.78 [1.74 to 1.82], p <0.01), renal failure (OR, [1.69 [1.65 to 1.73], p <0.01) and weight loss (OR, 1.40 [1.36 to 1.43], p <0.01). In summary, in-hospital mortality from native valve IE has been decreasing but total hospitalization and average cost of stay has increased.

Project description:We compared rates of unintentional injury (UI) deaths (total and by injury category) among Alaska Native (AN) people to rates of U.S. White (USW) and Alaska White (AKW) populations during 2006-2015. The mortality data for AN and AKW populations were obtained from Alaska Bureau of Vital Statistics and USW mortality data were obtained from WISQARS, the Center for Disease Control and Prevention online injury data program. AN and AKW rates were age-adjusted to the U.S. 2000 Standard Population and rate ratios (RR) were calculated. AN people had higher age-adjusted total UI mortality than the USW (RR = 2.6) and AKW (RR = 2.3) populations. Poisoning was the leading cause of UI death among AN people (35.9 per 100,000), more than twice that of USW (RR = 2.9) and AKW (RR = 2.5). Even greater disparities were found between AN people and USW for: natural environment (RR = 20.7), transport-other land (RR = 12.4), and drowning/submersion (RR = 9.1). Rates of AN UI were markedly higher than rates for either USW or AKW. Identifying all the ways in which alcohol/drugs contribute to UI deaths would aid in prevention efforts. All transportation deaths should be integrated into one fatality rate to provide more consistent comparisons between groups.

Project description:BackgroundThe objective of the study was to examine overall anemia management trends in non-dialysis patients with chronic kidney disease (CKD) from 2006 to 2015, and to evaluate the impact of Trial to Reduced Cardiovascular Events with Ananesp Therapy (TREAT)'s study results (October 2009) and the US Food and Drug Administration (FDA)'s (June 2011) safety warnings and guidelines on the use of ESA therapy in the current treatment of anemia.MethodsA retrospective cohort analysis of anemia management in CKD patients using Truven MarketScan Commercial and Medicare Supplemental databases was conducted. Monthly rates and types of anemia treatment for post-TREAT and post-FDA safety warning periods were compared to pre-TREAT period. Anemia management included ESA, intravenous iron, and blood transfusion. A time-series analysis using Autoregressive Integrated Moving Average (ARIMA) model and a Generalized Estimating Equation (GEE) model were used.ResultsBetween 2006 and 2015, CKD patients were increasingly less likely to be treated with ESAs, more likely to receive intravenous iron supplementation, and blood transfusions. The adjusted probabilities of prescribing ESAs were 31% (odds ratio (OR) = 0.69, 95% confidence interval (CI): 0.67-0.71) and 59% (OR = 0.41, 95% CI: 0.40, 0.42) lower in the post-TREAT and post-FDA warning periods compared to pre-TREAT period. The probability of prescribing intravenous iron was increased in the post-FDA warning period (OR = 1.11, 95% CI: 1.03-1.19) although the increase was not statistically significant in the post-TREAT period (OR = 1.03, 95% CI: 0.94-1.12). The probabilities of prescribing blood transfusion during the post-TREAT and post-FDA warning periods increased by 14% (OR = 1.14, 95% CI: 1.06-1.23) and 31% (OR = 1.31, 95% CI: 1.22-1.39), respectively. Similar trends of prescribing ESAs and iron supplementations were observed in commercially insured CKD patients but the use of blood transfusions did not increase.ConclusionsAfter the 2011 FDA safety warnings, the use of ESA continued to decrease while the use of iron supplementation continued to increase. The use of blood transfusions increased significantly in Medicare patients while it remained stable in commercially insured patients. Results suggest the TREAT publication had effected treatment of anemia prior to the FDA warning but the FDA warning solidified TREAT's recommendations for anemia treatment for non- dialysis dependent CKD patients.

Project description:BackgroundMethamphetamine is the most prevalent drug in the mainland of China, yet few studies on the non-medical use of methamphetamine nationwide have been conducted. This study aimed to examine the trends in the prevalence of non-medical methamphetamine use and to explore the flow pattern of internal migrant methamphetamine users in the mainland of China.MethodsData were extracted from the National Dynamic Management and Control Database for Drug Users (NDMCD). Joinpoint regressions were used to examine trends in the prevalence and population size of methamphetamine use.ResultsA total of 1,821,468 methamphetamine use cases registered in NDMCD from 2006 to 2015 were identified. The number of methamphetamine use cases presented an increasing trend in all age subgroups, and among them, the elderly increased the fastest [annual percent change (APC2006-2015), 122.9; 95% CI, 113.0-133.3; p < 0.001]. The prevalence of methamphetamine use increased from 4.69 per 100,000 population in 2008 to 45.38 per 100,000 population in 2015 (APC2008-2015, 36.1; 95% CI, 31.9-40.6; p < 0.001). The regions of the Pearl River Delta, Yangtze River Delta, and Beijing-Tianjin-Hebei Urban Agglomeration absorbed over 96% of all internal migrant methamphetamine use cases, and the number of migrant methamphetamine use cases presented increased trends in these three regions.ConclusionsThe increasing trends in methamphetamine use have become a threat to all age groups in China. Substance use prevention programs should focus on internal migrant drug users, especially in economically developed regions.
