This study examines the magnitude of reconciliation payments and clinical spending reductions necessary for the Centers for Medicare & Medicaid Services to break even in the first 4 performance periods of the BPCI-A (Bundled Payments for Care Improvement Advanced) program.

Differences in Treatment Patterns and Outcomes of Acute Myocardial Infarction for Low- and High-Income Patients in 6 Countries.

Importance: Differences in the organization and financing of health systems may produce more or less equitable outcomes for advantaged vs disadvantaged populations. We compared treatments and outcomes of older high- and low-income patients across 6 countries. Objective: To determine whether treatment patterns and outcomes for patients presenting with acute myocardial infarction differ for low- vs high-income individuals across 6 countries. Design, Setting, and Participants: Serial cross-sectional cohort study of all adults aged 66 years or older hospitalized with acute myocardial infarction from 2013 through 2018 in the US, Canada, England, the Netherlands, Taiwan, and Israel using population-representative administrative data. Exposures: Being in the top and bottom quintile of income within and across countries. Main Outcomes and Measures: Thirty-day and 1-year mortality; secondary outcomes included rates of cardiac catheterization and revascularization, length of stay, and readmission rates. Results: We studied 289 376 patients hospitalized with ST-segment elevation myocardial infarction (STEMI) and 843 046 hospitalized with non-STEMI (NSTEMI). Adjusted 30-day mortality generally was 1 to 3 percentage points lower for high-income patients. For instance, 30-day mortality among patients admitted with STEMI in the Netherlands was 10.2% for those with high income vs 13.1% for those with low income (difference, -2.8 percentage points [95% CI, -4.1 to -1.5]). One-year mortality differences for STEMI were even larger than 30-day mortality, with the highest difference in Israel (16.2% vs 25.3%; difference, -9.1 percentage points [95% CI, -16.7 to -1.6]). In all countries, rates of cardiac catheterization and percutaneous coronary intervention were higher among high- vs low-income populations, with absolute differences ranging from 1 to 6 percentage points (eg, 73.6% vs 67.4%; difference, 6.1 percentage points [95% CI, 1.2 to 11.0] for percutaneous intervention in England for STEMI). Rates of coronary artery bypass graft surgery for patients with STEMI in low- vs high-income strata were similar but for NSTEMI were generally 1 to 2 percentage points higher among high-income patients (eg, 12.5% vs 11.0% in the US; difference, 1.5 percentage points [95% CI, 1.3 to 1.8 ]). Thirty-day readmission rates generally also were 1 to 3 percentage points lower and hospital length of stay generally was 0.2 to 0.5 days shorter for high-income patients. Conclusions and Relevance: High-income individuals had substantially better survival and were more likely to receive lifesaving revascularization and had shorter hospital lengths of stay and fewer readmissions across almost all countries. Our results suggest that income-based disparities were present even in countries with universal health insurance and robust social safety net systems.

Racial Disparities in the Cost of Unplanned Hospitalizations after Breast Reconstruction.

BACKGROUND: Given the national attention to disparities in health care, understanding variation provided to minorities becomes increasingly important. This study will examine the effect of race on the rate and cost of unplanned hospitalizations after breast reconstruction procedures. METHODS: The authors performed an analysis comparing patients undergoing implant-based and autologous breast reconstruction in the Healthcare Cost and Utilization Project. The authors evaluated the rate of unplanned hospitalizations and associated expenditures among patients of different races. Multivariable analyses were performed to determine the association among race and readmissions and health care expenditures. RESULTS: The cohort included 17,042 patients. The rate of an unplanned visit was 5%. The rates of readmissions among black patients (6%) and Hispanic patients (7%) in this study are higher compared with white patients (5%). However, after controlling for patient-level characteristics, race was not an independent predictor of an unplanned visit. In our expenditure model, black patients [adjusted cost ratio, 1.35 (95% CI, 1.11 to 1.66)] and Hispanic patients [adjusted cost ratio, 1.34 (95% CI, 1.08 to 1.65)] experienced greater cost for their readmission compared with white patients. CONCLUSIONS: Although race is not an independent predictor of an unplanned hospital visit after surgery, racial minorities bear a higher cost burden after controlling for insurance status, further stimulating health care disparities. Adjusted payment models may be a strategy to reduce disparities in surgical care. In addition, direct and indirect measures of disparities should be used when examining health care disparities to identify consequences of inequities more robustly.

The Potential Cost-Effectiveness of a Machine Learning Tool That Can Prevent Untimely Intensive Care Unit Discharge.

OBJECTIVES: The machine learning prediction model Pacmed Critical (PC), currently under development, may guide intensivists in their decision-making process on the most appropriate time to discharge a patient from the intensive care unit (ICU). Given the financial pressure on healthcare budgets, this study assessed whether PC has the potential to be cost-effective compared with standard care, without the use of PC, for Dutch patients in the ICU from a societal perspective. METHODS: A 1-year, 7-state Markov model reflecting the ICU care pathway and incorporating the PC decision tool was developed. A hypothetical cohort of 1000 adult Dutch patients admitted in the ICU was entered in the model. We used the literature, expert opinion, and data from Amsterdam University Medical Center for model parameters. The uncertainty surrounding the incremental cost-effectiveness ratio was assessed using deterministic and probabilistic sensitivity analyses and scenario analyses. RESULTS: PC was a cost-effective strategy with an incremental cost-effectiveness ratio of €18 507 per quality-adjusted life-year. PC remained cost-effective over standard care in multiple scenarios and sensitivity analyses. The likelihood that PC will be cost-effective was 71% at a willingness-to-pay threshold of €30 000 per quality-adjusted life-year. The key driver of the results was the parameter "reduction in ICU length of stay." CONCLUSIONS: We showed that PC has the potential to be cost-effective for Dutch ICUs in a time horizon of 1 year. This study is one of the first cost-effectiveness analyses of a machine learning device. Further research is needed to validate the effectiveness of PC, thereby focusing on the key parameter "reduction in ICU length of stay" and potential spill-over effects.

Evaluation of Length of Stay, Care Volume, In-Hospital Mortality, and Emergency Readmission Rate Associated With Use of Diagnosis-Related Groups for Internal Resource Allocation in Public Hospitals in Hong Kong.

Importance: Hong Kong's internal resource allocation system for public inpatient care changed from a global budget system to one based on diagnosis-related groups (DRGs) in 2009 and returned to a global budget system in 2012. Changes in patient and hospital outcomes associated with moving from a DRG-based system to a global budget system for inpatient care have rarely been evaluated. Objective: To examine associations between the introduction and discontinuation of DRGs and changes in length of stay, volume of care, in-hospital mortality rates, and emergency readmission rates in the inpatient population in acute care hospitals overall, stratified by age group, and across 5 medical conditions. Design, Setting, and Participants: This cross-sectional study included data from patients aged 45 years or older who were hospitalized in public acute care settings in Hong Kong before the introduction (April 2006 to March 2009), during implementation (April 2009 to March 2012), and after discontinuation (April 2012 to November 2014) of the DRG scheme. Data analysis was conducted from January to June 2021. Exposures: Public hospitals transitioned from a global budget payment system to a DRG-based system in April 2009 and returned to a global budget system in April 2014. Main Outcomes and Measures: The main outcome was the association of use of DRGs with patient-level length of stay, in-hospital mortality rate, 1-month emergency readmission rate, and population-level number of admissions per month. An interrupted time series design was used to estimate changes in the level and slope of outcome variables after introduction and discontinuation of DRGs, accounting for pretrends. Results: This study included 7 604 390 patient episodes. Overall, the mean (SD) age of patients was 68.97 (13.20) years, and 52.17% were male. The introduction of DRGs was associated with a 1.77% (95% CI, 1.23%-2.32%) decrease in the mean length of stay, a 2.90% (95% CI, 2.52%-3.28%) increase in the number of patients admitted, a 4.12% (95% CI, 1.89%-6.35%) reduction in in-hospital mortality, and a 2.37% (95% CI, 1.28%-3.46%) decrease in emergency readmissions. Discontinuation of the DRG scheme was associated with a 0.93% (95% CI, 0.42%-1.44%) increase in the mean length of stay and a 1.82% (95% CI, 1.47%-2.17%) reduction in the number of patients treated after adjusting for covariates; no statistically significant change was observed in in-hospital mortality (-0.14%; 95% CI, -2.29% to 2.01%) or emergency readmission rate (-0.29%; 95% CI, -1.30% to 0.71%). Conclusions and Relevance: In this cross-sectional study, the introduction of DRGs was associated with shorter lengths of stay and increased hospital volume, and discontinuation was associated with longer lengths of stay and decreased hospital volume. In-hospital mortality and emergency readmission rates did not significantly change after discontinuation of DRGs.

Acute respiratory distress syndrome readmissions: A nationwide cross-sectional analysis of epidemiology and costs of care.

BACKGROUND: Acute Respiratory Distress Syndrome affects approximately 10% of patients admitted to intensive care units internationally, with as many as 40%-52% of patients reporting re-hospitalization within one year. RESEARCH QUESTION/AIM: To describe the epidemiology of patients with acute respiratory distress syndrome who require 30-day readmission, and to describe associated costs. STUDY DESIGN AND METHODS: A cross-sectional analysis of the 2016 Healthcare Cost and Utilization Project's Nationwide Readmission Database, which is a population-based administrative database which includes discharge data from U.S. hospitals. Inclusion criteria: hospital discharge records for adults age > 17 years old, with a diagnosis of ARDS on index admission, with associated procedure codes for endotracheal intubation and/or invasive mechanical ventilation, who were discharged alive. Primary exposure is adult hospitalization for meeting criteria as described. The primary outcome measure is 30-day readmission rate, as well as patient characteristics and time distribution of readmissions. RESULTS: Nationally, 25,170 admissions meeting criteria were identified. Index admission mortality rate was 37.5% (95% confidence interval [CI], 36.2-38.8). 15,730 records of those surviving hospitalization had complete discharge information. 30-day readmission rate was 18.4%, with 14% of total readmissions occurring within 2 calendar days of discharge; these early readmissions had higher mortality risk (odds ratio 1.82, 95% CI 1.05-6.56) compared with readmission in subsequent days. For the closest all-cause readmission within 30 days, the mean cost was $26,971, with a total national cost of over $75.6 million. INTERPRETATION: Thirty-day readmission occurred in 18.4% of patients with acute respiratory distress syndrome in this sample, and early readmission is strongly associated with increased mortality compared to late readmission. Further research is needed to clarify whether the rehospitalizations or associated mortalities are preventable.

National Trends in Post-Acute Care Costs Following Total Hip Arthroplasty from 2010 through 2018.

BACKGROUND: Post-acute care remains a target for episode-of-care cost reduction following total hip arthroplasty (THA). The introduction of bundled payment models in the United States in 2013 aligned incentives among providers to reduce post-acute care resource utilization. Institution-level studies have shown increased rates of home discharge with substantial cost savings after adoption of bundled payment models; however, national data have yet to be reported. The purpose of this study was to evaluate national trends in post-acute care utilization and costs following primary THA over the last decade. METHODS: We reviewed the cases of 189,847 patients undergoing primary THA during 2010 through 2018 from the PearlDiver database. Annual trends in patient demographics, discharge disposition, and post-acute care resource utilization were evaluated. Post-acute care reimbursements were standardized to 2020 dollars and included outpatient visits, prescriptions, physical therapy, home health, inpatient rehabilitation, skilled nursing facilities, and any rehospitalizations or emergency department (ED) visits within 90 days of surgery. RESULTS: From 2010 to 2018, the mean episode-of-care costs ($31,562 versus $24,188; p < 0.001) and overall post-acute care costs ($5,903 versus $3,485; p < 0.001) both declined. Post-acute care savings were primarily driven by reduced costs of skilled nursing facilities ($1,533 versus $627; p < 0.001), home health ($1,041 versus $763; p = 0.002), inpatient rehabilitation ($949 versus $552; p < 0.001), ED visits ($508 versus $102; p < 0.001), and rehospitalizations ($367 versus $179; p < 0.001). Post-acute care costs declined by $578 (p = 0.025) during 2010 to 2012, $768 (p = 0.038) during 2013 to 2015, and $884 (p = 0.020) during 2016 to 2018. CONCLUSIONS: Over the last decade, the rate of home discharge after THA increased while rehospitalization and ED visit rates declined, resulting in a substantial decrease in total and post-acute care costs. Post-acute care costs declined most rapidly after the introduction of the new Medicare bundled payment programs in 2013 and 2016.

Nationwide Readmissions Analysis of Minimally Invasive Versus Open Ventral Hernia Repair: A Retrospective Population-Based Study.

INTRODUCTION: Minimally invasive ventral hernia repair (MISVHR) has been performed for almost 30 years; recently, there has been an accelerated adoption of the robotic platform leading to renewed comparisons to open ventral hernia repair (OVHR). The present study evaluates patterns and outcomes of readmissions for MISVHR and OVHR patients. METHODS: The Nationwide Readmissions Database (NRD) was queried for patients undergoing OVHR and MISVHR from 2016 to 2018. Demographic characteristics, complications, and 90-day readmissions were determined. A subgroup analysis was performed to compare robotic ventral hernia repair (RVHR) vs laparoscopic hernia repair (LVHR). Standard statistical methods and logistic regression were used. RESULTS: Over the 3-year period, there were 25 795 MISVHR and 180 635 OVHR admissions. Minimally invasive ventral hernia repair was associated with a lower rate of 90-day readmission (11.3% vs 17.3%, P < .01), length of stay (LOS) (4.0 vs 7.9 days, P < .01), and hospital charges ($68,240 ± 75 680 vs $87,701 ± 73 165, P < .01), which remained true when elective and non-elective repairs were evaluated independently. Postoperative infection was the most common reason for readmission but was less common in the MISVHR group (8.4% vs 16.8%, P < .01). Robotic ventral hernia repair increased over the 3-year period and was associated with decreased LOS (3.7 vs 4.1 days, P < .01) and comparable readmissions (11.3% vs 11.2%, P = .74) to LVHR, but was nearly $20,000 more expensive. In logistic regression, OVHR, non-elective operation, urban-teaching hospital, increased LOS, comorbidities, and payer type were predictive of readmission. CONCLUSIONS: Open ventral hernia repair was associated with increased LOS and increased readmissions compared to MISVHR. Robotic ventral hernia repair had comparable readmissions and decreased LOS to LVHR, but it was more expensive.

Burden and Cost of Gastrointestinal, Liver, and Pancreatic Diseases in the United States: Update 2021.

BACKGROUND & AIMS: Gastrointestinal diseases account for considerable health care use and expenditures. We estimated the annual burden, costs, and research funding associated with gastrointestinal, liver, and pancreatic diseases in the United States. METHODS: We generated estimates using data from the National Ambulatory Medical Care Survey; National Hospital Ambulatory Medical Care Survey; Nationwide Emergency Department Sample; National Inpatient Sample; Kids' Inpatient Database; Nationwide Readmissions Database; Surveillance, Epidemiology, and End Results program; National Vital Statistics System; Centers for Disease Control and Prevention Wide-Ranging Online Data for Epidemiologic Research; MarketScan Commercial Claims and Encounters data; MarketScan Medicare Supplemental data; United Network for Organ Sharing registry; Medical Expenditure Panel Survey; and National Institutes of Health (NIH). RESULTS: Gastrointestinal health care expenditures totaled $119.6 billion in 2018. Annually, there were more than 36.8 million ambulatory visits for gastrointestinal symptoms and 43.4 million ambulatory visits with a primary gastrointestinal diagnosis. Hospitalizations for a principal gastrointestinal diagnosis accounted for more than 3.8 million admissions, with 403,699 readmissions. A total of 22.2 million gastrointestinal endoscopies were performed, and 284,844 new gastrointestinal cancers were diagnosed. Gastrointestinal diseases and cancers caused 255,407 deaths. The NIH supported $3.1 billion (7.5% of the NIH budget) for gastrointestinal research in 2020. CONCLUSIONS: Gastrointestinal diseases are responsible for millions of health care encounters and hundreds of thousands of deaths that annually costs billions of dollars in the United States. To reduce the high burden of gastrointestinal diseases, focused clinical and public health efforts, supported by additional research funding, are warranted.

Impact of opioid use disorder on resource utilization and readmissions after operative trauma.

BACKGROUND: Although patients with opioid use disorder have been shown to be more susceptible to traumatic injury, the impact of opioid use disorder after trauma-related admission remains poorly characterized. The present nationally representative study evaluated the association of opioid use disorder on clinical outcomes after traumatic injury warranting operative intervention. METHODS: The 2010 to 2018 Nationwide Readmissions Database was used to identify adult trauma victims who underwent major operative procedures. Injury severity was quantified using International Classification of Diseases Trauma Mortality Prediction Model. Entropy balancing was used to adjust for intergroup differences. Multivariable regression models were developed to assess the association of opioid use disorder on in-hospital mortality, perioperative complications, resource utilization, and readmissions. RESULTS: Of an estimated 5,089,003 hospitalizations, 54,097 (1.06%) had a diagnosis of opioid use disorder with increasing prevalence during the study period. Compared with others, opioid use disorder had a lower proportion of extremity injuries and falls but greater predicted mortality measured by Trauma Mortality Prediction Model. After adjustment, opioid use disorder was associated with decreased odds of in-hospital mortality (adjusted odds ratio: 0.61; 95% confidence interval, 0.53-0.70) but had greater likelihood of pneumonia, infectious complications, and acute kidney injury. Additionally, opioid use disorder was associated with longer hospitalization duration as well as greater index costs and risk of readmission within 30 days (adjusted odds ratio: 1.36; 95% confidence interval, 1.25-1.49). CONCLUSION: Opioid use disorder in operative trauma has significantly increased in prevalence and is associated with decreased in-hospital index mortality but greater resource utilization and readmission.

Lessons learned from value-based pediatric appendectomy care: A shared savings pilot model.

PURPOSE: We aim to assess the healthcare value achieved from a shared savings program for pediatric appendectomy. METHODS: All appendectomy patients covered by our health plan were included. Quality targets were 15% reduction in time to surgery, length of stay, readmission rate, and patient satisfaction. Quality targets and costs for an appendectomy episode in two 6-month performance periods (PP1, PP2) were compared to baseline. RESULTS: 640 patients were included (baseline:317, PP1:167, PP2:156). No quality targets were met in PP1. Two quality targets were met during PP2: readmission rate (-57%) and patient satisfaction. No savings were realized because the cost reduction threshold (-9%) was not met during PP1 (+1.7%) or PP2 (-0.4%). CONCLUSIONS: Payer-provider partnerships can be a platform for testing value-based reimbursement models. Setting achievable targets, identifying affectable quality metrics, considering case mix index, and allowing sufficient time for interventions to generate cost savings should be considered in future programs.

Procedural and 12-month in-hospital costs of primary infra-popliteal bypass surgery, infrapopliteal best endovascular treatment, and major lower limb amputation for chronic limb threatening ischemia.

OBJECTIVE: Chronic limb-threatening ischemia (CLTI) is a growing global problem due to the widespread use of tobacco and increasing prevalence of diabetes. Although the financial consequences are considerable, few studies have compared the relative cost-effectiveness of different CLTI management strategies. The Bypass vs Angioplasty in Severe Ischaemia of the Leg (BASIL)-2 trial is randomizing patients with CLTI to primary infrapopliteal (IP) vein bypass surgery (BS) or best endovascular treatment (BET) and includes a comprehensive within-trial cost-utility analysis. The aim of this study is to compare over a 12-month time horizon, the costs of primary IP BS, IP best endovascular treatment (BET), and major limb major amputation (MLLA) to inform the BASIL-2 cost-utility analysis. METHODS: We compared procedural human resource (HR) costs and total in-hospital costs for the index admission, and over the following 12-months, in 60 consecutive patients undergoing primary IP BS (n = 20), IP BET (n = 20), or MLLA (10 transfemoral and 10 transtibial) for CLTI within the BASIL prospective cohort study. RESULTS: Procedural HR costs were greatest for BS (BS £2551; 95% confidence interval [CI], £1934-£2807 vs MLLA £1130; 95% CI, £1046-£1297 vs BET £329; 95% CI, £242-£390; P < .001, Kruskal-Wallis) due to longer procedure duration and greater staff requirement. With regard to the index admission, MLLA was the most expensive due to longer hospital stay (MLLA £13,320; 95% CI, £8986-£18,616 vs BS £8714; 95% CI, £6097-£11,973 vs BET £4813; 95% CI, £3529-£6097; P < .001, Kruskal-Wallis). The total cost of the index admission and in-hospital care over the following 12 months remained least for BET (MLLA £26,327; 95% CI, £17,653-£30,458 vs BS £20,401; 95% CI, £12,071-£23,926 vs BET £12,298; 95% CI, £6961-£15,439; P < .001, Kruskal-Wallis). CONCLUSIONS: Over a 12-month time horizon, MLLA and IP BS are more expensive than IP BET in terms of procedural HR costs and total in-hospital costs. These economic data, together with quality of life data from BASIL-2, will inform the calculation of incremental cost-effectiveness ratios for different CLTI management strategies within the BASIL-2 cost-utility analysis.

Luck of the draw: Role of chance in the assignment of medicare readmissions penalties.

Pay-for-performance programs are one strategy used by health plans to improve the efficiency and quality of care delivered to beneficiaries. Under such programs, providers are often compared against their peers in order to win bonuses or face penalties in payment. Yet luck has the potential to affect performance assessment through randomness in the sorting of patients among providers or through random events during the evaluation period. To investigate the impact luck can have on the assessment of performance, we investigated its role in assigning penalties under Medicare's Hospital Readmissions Reduction Policy (HRRP), a program that penalizes hospitals with excess readmissions. We performed simulations that estimated program hospitals' 2015 readmission penalties in 1,000 different hypothetical fiscal years. These hypothetical fiscal years were created by: (a) randomly varying which patients were admitted to each hospital and (b) randomly varying the readmission status of discharged patients. We found significant differences in penalty sizes and probability of penalty across hypothetical fiscal years, signifying the importance of luck in readmission performance under the HRRP. Nearly all of the impact from luck arose from events occurring after hospital discharge. Luck played a smaller role in determining penalties for hospitals with more beds, teaching hospitals, and safety-net hospitals.

Trends in the quality and cost of inpatient surgical procedures in the United States, 2002-2015.

OBJECTIVES: This 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. METHODS: We 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. RESULTS: We 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. CONCLUSIONS: Our 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.

Timing and Cost of Wound Complications After Colorectal Resection.

BACKGROUND: More than 50% of postoperative wound complications occur after discharge. They are the most common postoperative complication and the most common reason for readmission after a surgical procedure. Little is known about the long-term costs of postdischarge wound complications after surgery. OBJECTIVE: We sought to understand the differences in costs and characteristics of wound complications identified after hospital discharge for patients undergoing colorectal surgery in comparison with in-hospital complications. DESIGN: This is an observational cohort study using Veterans Health Administration Surgical Quality Improvement Program data. SETTING: This study was conducted at a Veterans Affairs medical center. SETTING: Patients undergoing colorectal resection between October 1, 2007 and September 30, 2014. MAIN OUTCOME MEASURES: The primary outcomes measured were adjusted costs of care at discharge, 30 days, and 90 days after surgery. RESULTS: Of 20,146 procedures, 11.9% had a wound complication within 30 days of surgery (49.2% index-hospital, 50.8% postdischarge). In comparison with patients with index-hospital complications, patients with postdischarge complications had fewer superficial infections (65.0% vs 72.2%, p < 0.01), more organ/space surgical site infections (14.3% vs 10.1%, p < 0.01), and higher rates of diabetes (29.1% vs 25.0%, p = 0.02), and they were to have had a laparoscopic approach for their surgery (24.7% vs 18.2%, p < 0.01). The average cost including surgery at 30 days was $37,315 (SD = $29,319). Compared with index-hospital wound complications, postdischarge wound complications were $9500 (22%, p < 0.001) less expensive at 30 days and $9736 (15%, p < 0.001) less expensive at 90 days. Patients with an index-hospital wound complication were 40% less likely to require readmission at 30 days, but their readmissions were $12,518 more expensive than readmissions among patients with a newly identified postdischarge wound complication (p < 0.001). LIMITATIONS: This study was limited to patient characteristics and costs accrued only within the Veterans Affairs system. CONCLUSIONS: Patients with postdischarge wound complications have lower 30- and 90-day postoperative costs than those with wound complications identified during their index hospitalization and almost half were managed as an outpatient. TIEMPO Y COSTO DE LAS COMPLICACIONES LA HERIDA DESPUS DE LA RESECCIN COLORRECTAL: ANTECEDENTES:Más del 50% de complicaciones postoperatorias de la herida ocurren después del alta. Es la complicación postoperatoria más común y el motivo más frecuente de reingreso después del procedimiento quirúrgico. Poco se sabe sobre los costos a largo plazo de las complicaciones de la herida después del alta quirúrgica.OBJETIVO:Intentar en comprender las diferencias en los costos y las características de las complicaciones de la herida, identificadas después del alta hospitalaria, en pacientes sometidos a cirugía colorrectal, en comparación con las complicaciones intrahospitalarias.DISEÑO:Estudio de cohorte observacional utilizando datos del Programa de Mejora de la Calidad Quirúrgica de la Administración de Salud de Veteranos.ENTORNO CLÍNICO:Administración de Veteranos.PACIENTES:Pacientes sometidos a resección colorrectal entre el 1/10/2007 y el 30/9/2014.PRINCIPALES MEDIDAS DE VALORACIÓN:Costos de atención ajustados al alta, 30 días y 90 días después de la cirugía.RESULTADOS:De 20146 procedimientos, el 11,9% tuvo una complicación de la herida dentro de los 30 días de la cirugía. (49,2% índice hospitalario, 50,8% después del alta). En comparación con los pacientes, del índice de complicaciones hospitalarias, los pacientes con complicaciones posteriores al alta, tuvieron menos infecciones superficiales (65,0% frente a 72,2%, p <0,01), más infecciones de órganos/espacios quirúrgicos (14,3% frente a 10,1%, p <0,01), tasas más altas de diabetes (29,1% versus 25,0%, p = 0,02), y deberían de haber tenido un abordaje laparoscópico para su cirugía (24,7% versus 18,2%, p <0,01). El costo promedio, incluida la cirugía a los 30 días, fue de $ 37,315 (desviación estándar = $ 29,319). En comparación con el índice de complicaciones de las herida hospitalaria, las complicaciones de la herida después del alta fueron $ 9,500 (22%, p <0,001) menor costo a los 30 días y $ 9,736 (15%, p<0,001) y menor costo a los 90 días. Los pacientes con índice de complicación de la herida hospitalaria, tenían un 40% menos de probabilidades de requerir reingreso a los 30 días, pero sus reingresos eran $ 12,518 más costosos que los reingresos entre los pacientes presentando complicación de la herida recién identificada después del alta (p <0,001).LIMITACIONES:Limitado a las características del paciente y los costos acumulados solo dentro del sistema VA.CONCLUSIONES:Pacientes con complicaciones de la herida post alta, tienen menores costos postoperatorios a los 30 y 90 días, que aquellos con complicaciones de la herida identificadas durante su índice de hospitalización y aproximadamente la mitad fueron tratados de forma ambulatoria.

A 24-month retrospective update: follow-up hospitalization charges and readmissions in US lumbar fusion surgeries using a cellular bone allograft (CBA) versus recombinant human bone morphogenetic protein-2 (rhBMP-2).

BACKGROUND: The objectives of this study were to build upon previously-reported 12-month findings by retrospectively comparing 24-month follow-up hospitalization charges and potentially-relevant readmissions in US lumbar fusion surgeries that employed either recombinant human bone morphogenetic protein-2 (rhBMP-2) or a cellular bone allograft comprised of viable lineage-committed bone cells (V-CBA) via a nationwide healthcare system database. METHODS: A total of 16,172 patients underwent lumbar fusion surgery using V-CBA or rhBMP-2 in the original study, of whom 3,792 patients (23.4%) were identified in the current study with all-cause readmissions during the 24-month follow-up period. Confounding baseline patient, procedure, and hospital characteristics found in the original study were used to adjust multivariate regression models comparing differences in 24-month follow-up hospitalization charges (in 2020 US dollars) and lengths of stay (LOS; in days) between the groups. Differences in potentially-relevant follow-up readmissions were also compared, and all analyses were repeated in the subset of patients who only received treatment at a single level of the spine. RESULTS: The adjusted cumulative mean 24-month follow-up hospitalization charges in the full cohort were significantly lower in the V-CBA group ($99,087) versus the rhBMP-2 group ($124,389; P < 0.0001), and this pattern remained in the single-level cohort (V-CBA = $104,906 vs rhBMP-2 = $125,311; P = 0.0006). There were no differences between groups in adjusted cumulative mean LOS in either cohort. Differences in the rates of follow-up readmissions aligned with baseline comorbidities originally reported for the initial procedure. Subsequent lumbar fusion rates were significantly lower for V-CBA patients in the full cohort (10.12% vs 12.00%; P = 0.0002) and similar between groups in the single-level cohort, in spite of V-CBA patients having significantly higher rates of baseline comorbidities that could negatively impact clinical outcomes, including bony fusion. CONCLUSIONS: The results of this study suggest that use of V-CBA for lumbar fusion surgeries performed in the US is associated with substantially lower 24-month follow-up hospitalization charges versus rhBMP-2, with both exhibiting similar rates of subsequent lumbar fusion procedures and potentially-relevant readmissions.

Factors associated with unplanned readmissions and costs following resection of brain metastases in the United States.

The purpose of this study was to critically analyze the risk of unplanned readmission following resection of brain metastasis and to identify key risk factors to allow for early intervention strategies in high-risk patients. We analyzed data from the Nationwide Readmissions Database (NRD) from 2010-2014, and included patients who underwent craniotomy for brain metastasis, identified using ICD-9-CM diagnosis (198.3) and procedure (01.59) codes. The primary outcome of the study was unplanned 30-day all-cause readmission rate. Secondary outcomes included reasons and costs of readmissions. Hierarchical logistic regression model was used to identify the factors associated with 30-day readmission following craniotomy for brain metastasis. During the study period, 44,846 index hospitalizations occurred for patients who underwent resection of brain metastasis. In this cohort, 17.8% (n = 7,965) had unplanned readmissions within the first 30 days after discharge from the index hospitalization. The readmission rate did not change significantly during the five-year study period (p-trend = 0.286). The median per-patient cost for 30-day unplanned readmission was $11,109 and this amounted to a total of $26.4 million per year, which extrapolates to a national expenditure of $269.6 million. Increasing age, male sex, insurance status, Elixhauser comorbidity index, length of stay, teaching status of the hospital, neurological complications and infectious complications were associated with 30-day readmission following discharge after an index admission for craniotomy for brain metastasis. Unplanned readmission rates after resection of brain metastasis remain high and involve substantial healthcare expenditures. Developing tools and interventions to prevent avoidable readmissions could focus on the high-risk patients as a future strategy to decrease substantial healthcare expense.

[Episode-based bundled payment model: evaluation of medical costs for early operable breast cancer]. / Financement à l'épisode de soins : évaluation du coût d'une chirurgie première pour cancer du sein précoce.

INTRODUCTION: Episode-based bundled payment model is actually opposing to fee-for-service model, intending to incentivize coordinated care. The aims of these study were to determine episode-based costs for surgery in early breast cancer patients and to propose a payment model. METHODS: OPTISOINS01 was a multicenter prospective study including early breast cancer patients from diagnosis to one-year follow up. Direct medical costs, quality and patient reported outcomes were collected. RESULTS: Data from 604 patients were analyzed. Episode-based costs for surgery were higher in case of: planned radical surgery (OR=9,47 ; IC95 % [3,49-28,01]; P<0,001), hospitalization during more than one night (OR=6,73; IC95% [2,59-17,46]; P<0,001), home hospitalization (OR=11,07 ; IC95 % [3,01-173][3,01-54][3,01-543][3,01-54,33]; P<0,001) and re-hospitalization (OR=25,71 ; IC95 % [9,24-89,17; P<0,001). The average cost was 5 268 € [2 947-18 461] when a lumpectomy was planned and 7408 € [4 222-22 565] in case of radical mastectomy. Bootstrap method was applied for internal validation of the cost model showing the reliability of the model with an area under the curve of 0,83 (95 % CI [0,80-0,86]). Care quality and patient reported outcomes were not related to the costs. DISCUSSION: This is the first report of episode-based costs for breast cancer surgery. An external validation will be necessary to validate our payment model.
