Inpatient Hospital Charge Variability of U.S. Hospitals.
Ontology highlight
ABSTRACT: Background
The range of hospital charges for similar diagnoses show tremendous variability across U.S. hospitals. This charge variability remains unexplained.Objective
We aimed to describe hospital charge variability in the U.S. and examine its relationship to local health factors.Design
This was a descriptive study of the 2011 Medicare Inpatient Charge data summarizing inpatient hospital charges billed to Medicare. This data was evaluated using 29 county-level measures of health status, health behavior, clinical access and quality, built environment, and socioeconomic status in a clustered, multivariate linear regression.Participants
2871 U.S. hospitals registered with Medicare and with at least ten discharges for diagnosis-related groups (DRGs) of six common inpatient conditions.Main measure
Inpatient hospital charges were assessed.Key results
No community health measures were associated with hospital charges. The one notable exception associated with higher charges was higher rates of uninsured status ($344.84 higher charges for every one-percentage point increase in prevalence (p < 0.001)). One variable was associated with lower hospital charges: the percentage of children living in poverty [$309.30 lower charges for every one-percentage point increase in prevalence (p < 0.001)].Conclusions
Overall, hospital charges lacked an association with population health measures, and their variability remains largely unexplained. However, the association of higher charges with uninsured status raises concerns about hospitals' price-setting strategies, such as price discrimination and cost-shifting strategies that expose vulnerable populations to great financial risks.

Project description:Analysts estimating the costs or cost-effectiveness of health interventions requiring hospitalization often cut corners because they lack data and the costs of undertaking full step-down costing studies are high. They sometimes use the costs taken from a single hospital, sometimes use simple rules of thumb for allocating total hospital costs between general inpatient care and the outpatient department, and sometimes use the average cost of an inpatient bed-day instead of a ward-specific cost.In this paper we explore for the first time the extent and the causes of variation in ward-specific costs across hospitals, using data from China. We then use the resulting model to show how ward-specific costs for hospitals outside the data set could be estimated using information on the determinants identified in the paper.Ward-specific costs estimated using step-down costing methods from 41 hospitals in 12 provinces of China were used. We used seemingly unrelated regressions to identify the determinants of variability in the ratio of the costs of specific wards to that of the outpatient department, and explain how this can be used to generate ward-specific unit costs.Ward-specific unit costs varied considerably across hospitals, ranging from 1 to 24 times the unit cost in the outpatient department--average unit costs are not a good proxy for costs at specialty wards in general. The most important sources of variability were the number of staff and the level of capacity utilization.More careful hospital costing studies are clearly needed. In the meantime, we have shown that in China it is possible to estimate ward-specific unit costs taking into account key determinants of variability in costs across wards. This might well be a better alternative than using simple rules of thumb or using estimates from a single study.

Project description:OBJECTIVE:To examine the effects of hospital and insurer markets concentration on transaction prices for inpatient hospital services. DATA SOURCES:Measures of hospital and insurer markets concentration derived from American Hospital Association and HealthLeaders-InterStudy data are linked to 2005-2008 inpatient administrative data from Truven Health MarketScan Databases. STUDY DESIGN:Uses a reduced-form price equation, controlling for cost and demand shifters and accounting for possible endogeneity of market concentration using instrumental variables (IV) technique. PRINCIPAL FINDINGS:The findings suggest that greater hospital concentration raises prices, whereas greater insurer concentration depresses prices. A hypothetical merger between two of five equally sized hospitals is estimated to increase hospital prices by about 9 percent (p < .001). A similar merger of insurers would depress prices by about 15.3 percent (p < .001). Over the 2003-2008 periods, the estimates imply that hospital consolidation likely raised prices by about 2.6 percent, while insurer consolidation depressed prices by about 10.8 percent. Additional analysis using longer panel data and applying hospital fixed effects confirms the impact of hospital concentration on prices. CONCLUSION:The findings provide support for strong antitrust enforcement to curb rising hospital service prices and health care costs.

Project description:ObjectiveTo compare the outcomes of transapical transcatheter aortic valve replacement (TA-TAVR) and surgical aortic valve replacement (SAVR) using a large US population sample.MethodsThe U.S. National Inpatient Sample was queried for all patients who underwent TA-TAVR or SAVR during the years 2016-2017. The primary outcome was all-cause in-hospital mortality. Secondary outcomes were in-hospital stroke, pericardiocentesis, pacemaker insertion, mechanical ventilation, vascular complications, major bleeding, acute kidney injury, length of stay, and cost of hospitalization. Outcomes were modeled using multi-variable logistic regression for binary outcomes and generalized linear models for continuous outcomes.ResultsA total of 1560 TA-TAVR and 44,280 SAVR patients were included. Patients who underwent TA-TAVR were older and frailer. Compared to SAVR, TA-TAVR correlated with a higher mortality (4.5% vs. 2.7%, effect size (SMD) = 0.1) and higher periprocedural complications. Following multivariable analysis, both TA-TAVR and SAVR had a similar adjusted risk for in-hospital mortality. TA-TAVR correlated with lower odds of bleeding with (adjusted OR (aOR) = 0.26; 95% CI: 0.18-0.38;P < 0.001), and a shorter length of stay (adjusted mean ratio (aMR) = 0.77; 95% CI: 0.69-0.84; P < 0.001), but higher cost (aMR = 1.18; 95% CI: 1.10-1.28; P < 0.001). No significant differences in other study outcomes. In subgroup analysis, TA-TAVR in patients with chronic lung disease had higher odds for mortality (aOR = 3.11; 95%CI: 1.37-7.08; P = 0.007).ConclusionThe risk-adjusted analysis showed that TA-TAVR has no advantage over SAVR except for patients with chronic lung disease where TA-TAVR has higher mortality.

Project description:BackgroundTo address disparities in smoking rates, our safety-net hospital implemented an inpatient tobacco treatment intervention: an "opt-out" electronic health record (EHR)-based Best Practice Alert + order-set, which triggers consultation to a Tobacco Treatment Consult (TTC) service for all hospitalized patients who smoke cigarettes. We report on development, implementation, and adaptation of the intervention, informed by a pre-implementation needs assessment and two rapid-cycle evaluations guided by the Consolidated Framework for Implementation Research (CFIR) and Expert Recommendations for Implementing Change (ERIC) compilation.MethodsWe identified stakeholders affected by implementation and conducted a local needs assessment starting 6 months-pre-launch. We then conducted two rapid-cycle evaluations during the first 6 months post-implementation. The CFIR informed survey and interview guide development, data collection, assessment of barriers and facilitators, and selection of ERIC strategies to implement and adapt the intervention.ResultsKey themes were: (1) Understanding the hospital's priority to improving tobacco performance metrics was critical in gaining leadership buy-in (CFIR Domain: Outer setting; Construct: External Policy and Incentives). (2) CFIR-based rapid-cycle evaluations allowed us to recognize implementation challenges early and select ERIC strategies clustering into 3 broad categories (conducting needs assessment; developing stakeholder relationships; training and educating stakeholders) to make real-time adaptations, creating an acceptable clinical workflow. (3) Minimizing clinician burden allowed the successful implementation of the TTC service. (4) Demonstrating improved 6-month quit rates and tobacco performance metrics were key to sustaining the program.ConclusionsRapid-cycle evaluations to gather pre-implementation and early-implementation data, focusing on modifiable barriers and facilitators, allowed us to develop and refine the intervention to improve acceptability, adoption, and sustainability, enabling us to improve tobacco performance metrics in a short timeline. Future directions include spreading rapid-cycle evaluations to promote implementation of inpatient tobacco treatment programs to other settings and assessing long-term sustainability and return on investment of these programs.

Project description:BackgroundChronic obstructive pulmonary disease (COPD) is the third-leading cause of early readmissions. The Centers for Medicare and Medicaid instituted a financial penalty for excessive COPD readmissions galvanizing hospitals to implement effective strategies to reduce readmissions. We evaluated a 6-month COPD Chronic Care Management Collaborative to support hospitals to reduce preventable COPD-related revisits.MethodsSites were recruited among nearly 300 Vizient, Inc., members. The Collaborative used performance improvement initiatives to assist with implementation of effective strategies. Participants submitted performance data for 2 outcome measures: emergency department (ED) and hospital revisits.ResultsForty-seven members enrolled (Part I+II: n=33; Part I: n=3; Part II: n=11) of which 23 submitted data (n=23/47). The majority (n=19/23, 83%) reduced rates of COPD-related ED and/or hospital revisits. Among all 23 sites, the change in ED visits went from 11.05% to 10.87%; among 7 sites with reductions in ED visits, the reduction was 12.7% to 9%. Among all 23 sites, there were not reductions in hospital readmissions (18.53% to 18.64%); among 7 sites with reductions, the readmission rate went from 20.1% to 15.6%. The mean reach across 17 hospitals reporting reach for their most successful measure at baseline was 35.2% (SD=26.7%) and for the other 6, reporting reach at follow-up was 73.8%% (SD=18.3%); of note, only 3 sites submitted both baseline and follow-up data.ConclusionsThe Collaborative successfully supported the majority of sites in reducing COPD-related ED and/or hospital revisits using subject matter experts and coaching strategies to support hospitals' implementation of COPD quality improvement interventions.

Project description:ObjectivesTo determine the total numbers of privileged and full-time equivalent intensivists in acute care hospitals with intensivists and compare the characteristics of hospitals with and without intensivists.DesignRetrospective analysis of the American Hospital Association Annual Survey Database (Fiscal Year 2015).SettingTwo-thousand eight-hundred fourteen acute care hospitals with ICU beds.PatientsNone.InterventionsNone.Measurements and main resultsOf the 2,814 acute care hospitals studied, 1,469 (52%) had intensivists and 1,345 (48%) had no intensivists. There were 28,808 privileged and 19,996 full-time equivalent intensivists in the 1,469 hospitals with intensivists. In these hospitals, the median (25-75th percentile) numbers of privileged and full-time equivalent intensivists were 11 (5-24) and 7 (2-17), respectively. Compared with hospitals without intensivists, hospitals with privileged intensivists were primarily located in metropolitan areas (91% vs 50%; p < 0.001) and at the aggregate level had nearly thrice the number of hospital beds (403,522 [75%] vs 137,146 [25%]), 3.6 times the number of ICU beds (74,222 [78%] vs 20,615 [22%]), and almost twice as many ICUs (3,383 [65%] vs 1,846 [35%]). At the hospital level, hospitals with privileged intensivists had significantly more hospital beds (median, 213 vs 68; p < 0.0001), ICU beds (median, 32 vs 8; p < 0.0001), a higher ratio of ICU to hospital beds (15.6% vs 12.6%; p < 0.0001), and a higher number of ICUs per hospital (2 vs 1; p < 0.0001) than hospitals without intensivists.ConclusionsAnalyzing the intensivist section of the American Hospital Association Annual Survey database is a novel approach to estimating the numbers of privileged and full-time equivalent intensivists in acute care hospitals with ICU beds in the United States. This methodology opens the door to an enhanced understanding of the current supply and distribution of intensivists as well as future research into the intensivist workforce.

Project description:Although prior work has investigated the interplay between demographic and intrasurvey correlations of Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) scores, these prior studies have not included geospatial analyses, or analyses that take into account location effects. Here, we report the results of a geospatial analysis (not equivalent to simple geographical analysis) of patient experience scores pertaining to pain. HCAHPS data collected in 2011 were examined to test the hypothesis that HCAHPS patient experience with pain management (PEPM) scores were geospatially distributed throughout the United States using Moran's Index, which measures the association between PEPM scores and hospital location. After limiting the dataset to hospitals in the continental United States with nonzero HCAHPS response rates, 3645 hospitals were included in the analyses. "Always" responses were geospatially clustered amongst the analyzed hospitals. Clustering was significant in all distances tested from 10 to 5000km (P<0.0001). We identified 6 demarcated groups of hospitals. Taken together, these results strongly suggest a regional geographic effect on PEPM scores. These results may carry policy implications for U.S. hospitals with regard to acute pain outcomes. Further analyses will be necessary to evaluate policy explanations and implications of the regional geographic differences in PEPM results.

Project description:To compare the prevalence, resource utilization, and mortality for pediatric severe sepsis identified using two established identification strategies.Observational cohort study from 2004 to 2012.Forty-four pediatric hospitals contributing data to the Pediatric Health Information Systems database.Children 18 years old or younger.We identified patients with severe sepsis or septic shock by using two International Classification of Diseases, 9th edition, Clinical Modification-based coding strategies: 1) combinations of International Classification of Diseases, 9th edition, Clinical Modification codes for infection plus organ dysfunction (combination code cohort); 2) International Classification of Diseases, 9th edition, Clinical Modification codes for severe sepsis and septic shock (sepsis code cohort). Outcomes included prevalence of severe sepsis, as well as hospital and ICU length of stay, and mortality. Outcomes were compared between the two cohorts examining aggregate differences over the study period and trends over time. The combination code cohort identified 176,124 hospitalizations (3.1% of all hospitalizations), whereas the sepsis code cohort identified 25,236 hospitalizations (0.45%), a seven-fold difference. Between 2004 and 2012, the prevalence of sepsis increased from 3.7% to 4.4% using the combination code cohort and from 0.4% to 0.7% using the sepsis code cohort (p < 0.001 for trend in each cohort). Length of stay (hospital and ICU) and costs decreased in both cohorts over the study period (p < 0.001). Overall, hospital mortality was higher in the sepsis code cohort than the combination code cohort (21.2% [95% CI, 20.7-21.8] vs 8.2% [95% CI, 8.0-8.3]). Over the 9-year study period, there was an absolute reduction in mortality of 10.9% (p < 0.001) in the sepsis code cohort and 3.8% (p < 0.001) in the combination code cohort.Prevalence of pediatric severe sepsis increased in the studied U.S. children's hospitals over the past 9 years, whereas resource utilization and mortality decreased. Epidemiologic estimates of pediatric severe sepsis varied up to seven-fold depending on the strategy used for case ascertainment.

Project description:BackgroundHospitals are closing after poor financial performance leaving many patients without access to medical care. Identifying the factors associated with financial distress offers hospitals avenues for potential intervention to avoid bankruptcy and closure.Materials and methodsWe performed a retrospective analysis of private U.S. hospitals' financial information from 2011 to 2018. A mixed effects logistic regression model was used with the primary outcome of hospital financial distress (based on the Altman Z-score).ResultsOur sample included 2,720 private hospitals contributing a total of 20,022 hospital-year observations. The proportion of hospitals experiencing financial distress each year ranged from 22.0% to 24.3%. For-profit status was associated with an increased odds of financial distress (adjusted odds ratio (aOR), 4.36 [95% Confidence Interval (CI) 3.05 - 6.24]) as compared to non-profit status. A higher share of hospital revenue from Medicaid was also associated with increased odds of financial distress (aOR for the highest quartile, 2.28 [95% CI 1.73 - 3.00]) as compared to the lowest quartile. A higher case mix index (aOR for the highest quartile, 0.32 [95% CI 0.23 - 0.46]) and an increased share of hospital revenue from outpatient services (aOR for the highest quartile, 0.34 [95% CI 0.23 - 0.49]) were associated with decreased odds of financial distress as compared to their respective lowest quartiles.ConclusionsA significant proportion of private U.S. hospitals experience financial distress. Increasing case complexity and the proportion of patient revenue from outpatient services may represent avenues to avoid financial distress.
