Variations in Site-Specific Costs for Infants Born Extremely Preterm in Canadian Neonatal Intensive Care Units.

OBJECTIVE: To quantify site-specific costs and their association with survival without major morbidity (SWMM) in Canada for neonates <28 weeks of gestation admitted to large tertiary neonatal intensive care units. METHODS: We conducted a retrospective analysis of infants born at <28 weeks of gestation and admitted to Canadian Neonatal Network sites from 2010 through 2021. Sites that cared for at least 50 eligible infants by gestational age in weeks over the study period were included. Using a validated costing algorithm that assessed physician, nursing, respiratory therapy, diagnostic imaging, transfusions, procedural, medication, and certain indirect costs, we calculated site and resource-specific costs in 2017 Canadian dollars (CAD) and evaluated their relationship with SWMM. RESULTS: Seven sites with 8180 (range 841-1605) eligible neonates with a mean (SD) gestation of 25.4 [1.3] weeks were included. Survival to discharge or transfer was 85.3% with a mean (SD) length of stay of 75 (46) days. The mean (SD) total and daily costs per neonate varied between $94 992 ($60 283) and $174 438 ($130 501) CAD and $1833 ($916) to $2307 ($1281) CAD, respectively. Between sites, there was no relationship between costs and SWMM. CONCLUSIONS: There was marked variation in costs and SWMM between sites in Canada with universal health care. The lack of concordance between both outcomes and costs among sites may provide possibilities for outcomes improvement and cost containment.

Independent Risk Factors and Economic Burden Associated With Delayed Extubation Following Pediatric Liver Transplantation.

BACKGROUND: Successful early extubation (EE) after liver transplant (LT) has been shown to reduce intensive care unit (ICU) and hospital length of stay and infectious, vascular, and sedation-related complications in adults. EE may not always be feasible in children, and many may require prolonged mechanical ventilation. Limited data exists regarding the candidacy of EE, risk factors, consequences, and hospital costs of delayed extubation (DE) in pediatric LT. METHODS: We conducted a retrospective review to investigate predictive factors and associated costs of EE and DE in infants and children after orthotopic LT at our institution between 2011 and 2021. RESULTS: Of 338 LT (median age 39 months, 54% females), 246 (73%) had EE (within 24 h of LT), while 27% had DE. Age < 1 year (p = 0.0019), diagnosis of biliary atresia (0.02), abnormal pre-LT echocardiogram (0.02), and patients with ongoing hospital admission before LT (0.0001) were independently associated with DE. Hospital costs were significantly (∼3-fold) higher (p < 0.0001) in the DE group. In addition, factors associated with increased total hospital costs were age < 1 year and hospitalization before LT. CONCLUSION: EE post-LT is feasible and merits a trial. The prevalence of DE though modest is associated with increased resource utilization and hospital costs. Children who can be extubated early and those at risk for DE can be identified pre-operatively for optimal planning and allocation of resources.

Risk Factors for Increased Hospital Costs for Primary Total Hip Arthroplasty.

BACKGROUND: Patient medical complexity increases the cost of primary total hip arthroplasty (THA). The goal of this study was to quantify the impact of specific medical comorbidities on the real hospital cost of primary THA. METHODS: This study consisted of a retrospective analysis of 1,222 patient encounters for Current Procedural Terminology code 27130 (primary THA) between January 2017 and March 2020 at a high-volume urban academic medical center. Patient demographics, comorbidities, and admission data were collected, and univariate and multivariate gamma regression analyses were performed to identify associations with increased costs incurred during THA admission. RESULTS: The median total cost for THA was $30,580. Univariate analysis showed increased cost for body mass index (BMI) > 35 versus BMI < 35 ($31,739 versus 30,071; P < .05), American Society of Anesthesiologists (ASA) score 3 to 4 versus ASA 1 to 2 ($32,268 versus 30,045; P < .05), prevalence of diabetes ($31,523 versus 30,379; P < .05), congestive heart failure ($34,814 versus 30,584; P < .05), peripheral vascular disease (PVD) ($35,369 versus 30,573; P < .05), chronic pulmonary disease (CPD) ($34,625 versus 30,405; P < .05), renal disease ($31,973 versus 30,352; P < .05), and increased length of stay (r = 0.424; P < .05). Multivariate gamma regression showed that BMI > 35 (relative risk [RR] = 1.05), ASA 3 to 4 (RR = 1.07), PVD (RR = 1.29), CPD (RR = 1.13), and renal disease (RR = 1.09) were independently associated with increased THA hospital cost (P < .01). Increased costs seen in BMI > 35 versus BMI < 35 patients were largely due to hospital room and board ($6,345 versus 5,766; P = .01) and operating room costs ($5,744 versus 5,185; P < .05). CONCLUSIONS: A BMI > 35, PVD, CPD, renal disease, and ASA 3 to 4 are associated with higher inpatient hospital costs for THA. LEVEL OF EVIDENCE: Level III; Retrospective cohort study.

Physician-Targeted Interventions Reduce Surgical Expense and Improve Value-Driven Health Outcomes.

INTRODUCTION: Increasing health-care costs in the United States have not translated to superior outcomes in comparison to other developed countries. The implementation of physician-targeted interventions to reduce costs may improve value-driven health outcomes. This study aimed to evaluate the effectiveness of physician-targeted interventions to reduce surgical expenses and improve care for patients undergoing total thyroidectomies. METHODS: Two separate face-to-face interventions with individual surgeons focusing on surgical expenses associated with thyroidectomy were implemented in two surgical services (endocrine surgery and otolaryngology) by the surgical chair of each service in Jun 2016. The preintervention period was from Dec 2014 to Jun 2016 (19 mo, 352 operations). The postintervention period was from July 2016 to January 2018 (19 mo, 360 operations). Descriptive statistics were utilized, and differences-in-differences were conducted to compare the pre and postintervention outcomes including cost metrics (total costs, fixed costs, and variable costs per thyroidectomy) and clinical outcomes (30-d readmission rate, days to readmission, and total length of stay). RESULTS: Patient demographics and characteristics were comparable across pre- and post-intervention periods. Post-intervention, both costs and clinical outcomes demonstrated improvement or stability. Compared to otolaryngology, endocrine surgery achieved additional savings per surgery post-intervention: mean total costs by $607.84 (SD: 9.76; P < 0.0001), mean fixed costs by $220.21 (SD: 5.64; P < 0.0001), and mean variable costs by $387.82 (SD: 4.75; P < 0.0001). CONCLUSIONS: Physician-targeted interventions can be an effective tool for reducing cost and improving health outcomes. The effectiveness of interventions may differ based on specialty training. Future implementations should standardize these interventions for a critical evaluation of their impact on hospital costs and patient outcomes.

Patient characteristics and procedural variables are associated with length of stay and hospital cost among unilateral primary total hip arthroplasty patients: a single-center retrospective cohort study.

BACKGROUND: Total hip arthroplasty (THA) is a successful treatment for many hip diseases. Length of stay (LOS) and hospital cost are crucial parameters to quantify the medical efficacy and quality of unilateral primary THA patients. Clinical variables associated with LOS and hospital costs haven't been investigated thoroughly. METHODS: The present study retrospectively explored the contributors of LOS and hospital costs among a total of 452 unilateral primary THA patients from January 2019 to January 2020. All patients received conventional in-house rehabilitation services within our institute prior to discharge. Outcome parameters included LOS and hospital cost while clinical variables included patient characteristics and procedural variables. Multivariable linear regression analysis was performed to assess the association between outcome parameters and clinical variables by controlling confounding factors. Moreover, we analyzed patients in two groups according to their diagnosis with femur neck fracture (FNF) (confine THA) or non-FNF (elective THA) separately. RESULTS: Among all 452 eligible participants (266 females and 186 males; age 57.05 ± 15.99 year-old), 145 (32.08%) patients diagnosed with FNF and 307 (67.92%) diagnosed with non-FNF were analyzed separately. Multivariable linear regression analysis revealed that clinical variables including surgery duration, transfusion, and comorbidity (stroke) among the elective THA patients while the approach and comorbidities (stoke, diabetes mellitus, coronary heart disease) among the confine THA patients were associated with a prolonged LOS (P < 0.05). Variables including the American Society of Anesthesiologists classification (ASA), duration, blood loss, and transfusion among the elective THA while the approach, duration, blood loss, transfusion, catheter, and comorbidities (stoke and coronary heart disease) among the confine THA were associated with higher hospital cost (P < 0.05). The results revealed that variables were associated with LOS and hospital cost at different degrees among both elective and confine THA. CONCLUSIONS: Specific clinical variables of the patient characteristics and procedural variables are associated the LOS and hospital cost, which may be different between the elective and confine THA patients. The findings may indicate that evaluation and identification of detailed perioperative factors are beneficial in managing perioperative preparation, adjusting patients' anticipation, decreasing LOS, and reducing hospital cost.

A Total Knee Arthroplasty Preoperative Optimization Program Managed by an Advanced Practice Provider (Physician Assistant) Decreases Complications and Cost: A Pilot Study.

BACKGROUND: Studies have shown that optimizing modifiable risk factors leads to improved outcomes, with decreased lengths of stay (LOS), readmissions, complications, and hospital costs. Our goal was to demonstrate that use of an advanced practice provider, physician assistant (PA), within an orthopaedic practice would support these outcomes. METHODS: A preoperative optimization program managed by a PA was instituted at an academic medical center. From November 2019 to December 2022, a pilot group of fifteen (15) consecutive primary total knee arthroplasty (TKA) patients who were successfully optimized with the PA-managed program prior to TKA were matched 2:1 to a cohort of thirty (30) TKA patients who did not undergo optimization. Demographics and the modified readmission risk assessment tool score were used to match patients. Variables evaluated included LOS, emergency department visits, and hospital readmissions within 30 and 90 days after surgery, complications, and hospital costs of care. RESULTS: Optimized patients had less complications (P = .004) and significantly shorter (P < .001) mean LOS (1.27 days vs 2.97 days) compared to nonoptimized patients. The difference of hospital cost between cohorts for the primary admission was significant (P = .049). When readmission costs were included, the average hospital cost for the nonoptimized group was significantly higher than the optimized group (P = .018). CONCLUSIONS: Preoperative optimization led by a PA demonstrated significant reductions in LOS and the costs of care between optimized and non-optimized patients, along with decreased complications.

Low value of inherited thrombophilia testing among patients with stroke or transient ischemic attack: A three-year retrospective study.

BACKGROUND/PURPOSE: Inherited thrombophilia testing in the acute inpatient setting is controversial and expensive, and rarely changes clinical management. We evaluated ordering patterns and results of inpatient inherited thrombophilia testing for patients who presented with an isolated acute ischemic stroke or transient ischemic attack (TIA) without concurrent venous thromboembolism. METHODS: We retrospectively analyzed patients admitted for acute ischemic stroke or TIA between January 1st, 2019 and December 31st, 2021 at Thomas Jefferson University Hospitals in Philadelphia, PA and who underwent inherited thrombophilia testing during the hospital admission. Charts were reviewed to determine stroke risk factors, test results, and clinical management. RESULTS: Among 2108 patients admitted for acute ischemic stroke or TIA (including branch and central retinal artery occlusions) during the study period, the study included 249 patients (median age 49.0 years, 50.2% female) who underwent inpatient testing for factor V Leiden, prothrombin G20210A variant, hyperhomocysteinemia, PAI-1 elevation, and deficiencies of protein C and S and antithrombin. 42.2% of patients had at least one abnormal test, and among the 1035 tests ordered, 14.3% resulted abnormal. However, 28% of abnormal tests were borderline positive antigen or activity assays that likely represented false positives. There was no significant difference in the likelihood of a positive test among patients without stroke risk factors vs those with risk factors (47.1% vs 40.9%, P = .428), nor any significant difference between those under vs over age 50 years (45.7% vs 38.3%, P = .237). No patients with an abnormal result had their clinical management changed as a result. Charges for the tests totaled $468,588 USD. CONCLUSIONS: Inherited thrombophilia testing in the hospital immediately following isolated acute arterial ischemic stroke or TIA was associated with high rates of likely false positive results and was expensive. Positive results did not change clinical management in a single case.

The association of frailty with clinical and economic outcomes among hospitalized older adults with hip fracture surgery.

Frailty is a common condition among older adults with hip fracture. In our study analyzing National Inpatient Sample data, frailty was found to be associated with up to six times increase in in-patient mortality, 55% increased length of hospital stay, and 29% increase in hospital cost. INTRODUCTION: Hip fracture is a significant public health issue posing adverse health outcomes and substantial economic burden to patients and society. Frailty is a prevalent geriatric condition associated with poor clinical outcome among older adults. The association between hip fracture and frailty on both clinical and economic outcomes at the national level has not been estimated. We aimed to determine the association between frailty and in-hospital mortality, length of hospital stay (LOS), and total hospital cost among older patients aged ≥ 65 years who underwent surgery for hip fracture. METHODS: We did an analysis of administrative data using the National Inpatient Sample (NIS) data from 2016 and 2017. Our analysis included data on 29,735 hospitalizations. We first conducted a descriptive analysis of the patient characteristics (demographics and clinical) and hospital-related factors. Three multivariable regression analysis models were then used to determine independent associations between frailty and in-hospital mortality, LOS, and total hospital cost. All three models were adjusted for patients' demographic and clinical characteristics and hospital-related factors. RESULTS: Moderate and high frailty risk were associated with higher odds of death (OR = 2.94 and 95% CI 1.91-4.51 and OR = 5.99 and 95% CI 3.79-9.47), increased LOS (17% and 55%, p < 0.0001), and higher total hospital cost (7% and 29%, p < 0.0001) respectively compared to low frailty risk. CONCLUSION: Frailty was associated with mortality, LOS, and hospital cost after adjusting for patient demographic, clinical, and hospital-related factors. Further research is needed to explore what pre-surgical measures can be assessed to mitigate in-hospital mortality and hospital cost in frail older patients hospitalized for hip fracture surgery.

Real-World Data on Liposomal Bupivacaine and Inpatient Hospital Costs After Colorectal Surgery.

INTRODUCTION: This study compared costs of care among colorectal surgery patients who received liposomal bupivacaine versus those who did not (control) from a health institution perspective. MATERIAL AND METHODS: This pharmacoeconomic evaluation was conducted among adults undergoing open or minimally invasive colorectal resection at an academic medical center from May 2016 to February 2018. Healthcare resource utilization was derived from the electronic health record. Total cost of care (2018 USD) was analyzed using a generalized linear model adjusted for American Society of Anesthesiologists score, enhanced recovery after surgery management, open surgery, opioid use before surgery, height, cancer, and age. The primary analysis used public costs. A sensitivity analysis used internal costs from the hospital to maximize internal validity. RESULTS: Of 486 included patients, 286 (59%) received liposomal bupivacaine. Total cost of care using public costs included perioperative local anesthetics (mean ± standard deviation [SD]: $392 ± 74 liposomal bupivacaine versus $8 ± 13 control), analgesics within 48 h after surgery (mean ± SD: $132 ± 99 liposomal bupivacaine versus $117 ± 127 control), postoperative ileus management (mean ± SD: $5 ± 51 liposomal bupivacaine versus $65 ± 284 control), and hospital length of stay (mean ± SD: $4459 ± 3576 liposomal bupivacaine versus $7769 ± 7082 control). Liposomal bupivacaine was associated with an adjusted absolute difference in total cost of care of -$1435 (95% confidence interval -$2401 to -$470; P = 0.004) using public costs and -$1345 (95% confidence interval -$2215 to -$476; P = 0.002) using internal costs. CONCLUSIONS: Use of liposomal bupivacaine in colorectal surgery was associated with a significant reduction in total cost of care that was predominately driven by reduced costs for hospital stay and postoperative ileus management despite higher medication costs.

Trends in hospitalisation for common paediatric infections: An Australian experience.

AIM: Respiratory tract infections (RTIs) and acute gastroenteritis (AGE) significantly impact health service use among children; however, recent trends in hospital admission rates are not well documented. Our objectives were to describe admission rates for RTI and AGE among children in one jurisdiction over a 10-year period and their associated length of stay (LOS), monetary costs and chronic conditions. METHODS: This is retrospective review of hospital admissions data for Australian Capital Territory residents aged 0-16 years admitted with a primary diagnosis commensurate with RTI or AGE. RESULTS: Between 2009 and 2018, there were 8668 admissions. Admission rates rose from 9.2/1000 age-adjusted population in 2009 to 10.5/1000 in 2018. LOS reduced by 10 h (43 to 33 h). The median cost per admission was AUD$3158 (AUD$148 to AUD$175 271) and 16.4% of children had a chronic condition, associated with longer LOS and higher episode costs. Median age at admission was 1 year 5 months. Infants were admitted three times as often as older children and admissions for lower RTI were more common than for upper RTI or AGE (P < 0.001). CONCLUSIONS: Paediatric hospital admission rates for RTI in the Australian Capital Territory are increasing and LOS is decreasing. Admissions for AGE remain relatively low following the introduction of the rotavirus vaccine in 2007. Effective strategies are needed to reduce the burden of paediatric RTI.

The impact of price transparency and competition on hospital costs: a research on all-payer claims databases.

BACKGROUND: Public reporting has been considered effective in reducing health care costs by mitigating information asymmetry in the market as payers have incorporated publicly available information mandates into pay-for-performance programs and value-based purchasing. Therefore, hospitals have faced increasing pressures to provide price transparency. Despite the widespread promotion of healthcare transparency, the effectiveness of public reporting has not yet been sufficiently understood. This study analyzed the impact of transparency policy and competition on hospital costs by taking the state operations of all-payer claims databases (APCDs) as a case of interest. METHODS: We employed a fixed-effects regression, which allows the generation of hospital-specific effects, in accordance with the suggestion by the Hausman test. The study samples comprise nonprofit and for-profit general acute care hospitals in the United States for 2011-2017. The finalized dataset ranges from 3547 observations in 2011 to 3405 observations in 2015 after removing missing values. RESULTS: We found that hospitals in the states with APCDs tend to bear higher average operating expenses than those without APCDs, which may indicate that states maintaining higher healthcare expenditures are more attentive to a price transparency initiative and tend to adopt APCDs. With regard to competition, the results showed that weak market competition is significantly associated with higher operating costs, supporting the traditional competition theory. However, the combined effect of APCDs and competition did not indicate a significant association with operating expenses. Further investigation showed a continued tendency for a weak intensity of competition to be linked to lower hospital operating costs in states without APCDs. For those located in non-APCD adopted states, market consolidation helped hospitals coordinate care more effectively, economize operating costs, and enjoy economies of scale due to their large size. Similar trends did not appear in APCD-adopted states except for in 2015. CONCLUSIONS: This study observed limited evidence of the impact of APCDs and market competition. Our findings suggest that states need to make multifaceted efforts to contain hospital costs, not solely depending on the rollout of cost information or market competition. Market concentration may lead to coordinated care or cost economization in some cases. Still, the existing literature also demonstrates some potentially harmful impacts of increased concentration in the healthcare market, such as inefficient use of resources, unilateral market power, and deterrence of innovation. The introduction of a price transparency tool may require additional policy actions that take market competition into consideration.

Ambient sulfur dioxide and hospital expenditures and length of hospital stay for respiratory diseases: A multicity study in China.

BACKGROUND: Ambient sulfur dioxide (SO2) has been associated with morbidity and mortality of respiratory diseases, however, its effect on length of hospital stays (LOS) and cost for these diagnoses remain unclear. METHODS: We collected hospital admission information for respiratory diseases from all 11 cities in the Shanxi Province of China during 2017-2019. We assessed individual-level exposure by using an inverse distance weighting approach based on geocoded residential addresses. A generalized additive model was built to delineate city-specific effects of SO2 on hospitalization, hospital expenditure, and length of hospital stay for respiratory diseases. The overall effects were obtained by random-effects meta-analysis. We further estimated the respiratory burden attributable to SO2 by comparing different reference concentrations. RESULTS: We observed significant effects of SO2 exposure on respiratory diseases. At the provincial level, each 10 µg/m3 increase in SO2 on lag03 was associated with a 0.63% (95% CI: 0.14-0.11) increase in hospital admission, an increase of 4.56 days (95% CI: 1.16-7.95) of hospital stay, and 3647.97 renminbi (RMB, Chinese money) (95% CI: 1091.05-6204.90) in hospital cost. We estimated about 6.13 (95% CI: 1.33-11.10) thousand hospital admissions, 65.77 million RMB (95% CI: 19.67-111.87) in hospital expenditure, and 82.13 (95% CI: 20.87-143.40) thousand days of hospital stay could have potentially been avoided had the daily SO2 concentrations been reduced to WHO's reference concentration (40 µg/m3). Variable values in correspondence with this reference concentration could reduce the hospital cost and LOS of each case by 52.67 RMB (95% CI: 15.75-89.59) and 0.07 days (95% CI: 0.02-0.117). CONCLUSION: This study provides evidence that short-term ambient SO2 exposure is an important risk factor of respiratory diseases, indicating that continually tightening policies to reduce SO2 levels could effectively reduce respiratory disease burden in Shanxi Province.

[Economic evaluation of porous metal cones in total knee arthroplasty]. / Étude de l'impact économique des cônes en métal poreux dans les arthroplasties totales du genou.

INTRODUCTION: The use of porous metal cones (PMC) to fill bone loss during knee replacements is increasing, but these medical devices are not reimbursed in addition to diagnosis related tariffs (DRTs). The economic impact of PMC may be significant for hospitals. MATERIAL AND METHODS: This multicenter observational study includes all patients who benefited of a total knee prosthesis, with reconstruction by PMC, between June 2014 and June 2019, in two French university hospitals. The costs of each diagnosis related group (DRG) was evaluated using the "étude nationale des coûts à méthodologie commune (ENC)". The PMC costs were compared with the amounts of DRG and with the fares perceived by the hospital from the French sickness fund (DRTs). RESULTS: 96 patients (103 stays) benefited from the implantation of 195 cones. The hospital incomes were 10,970±1401€ /stay. Spending associated with PMC represented 35% of DRGs and 44% of DRTs. The average additional cost related to the cones was 2709±1138€ /stay. If the reconstructions had been performed by allograft, the average gain for hospitals would have been 108€ /stay. CONCLUSION: If PMC have clinical benefits for surgeons in reducing the incidence of revision, this study shows the inadequacy of the funding of these devices for French hospitals. This suggests the need to expand the possibilities of supporting innovative technologies.

Delirium Among Hospitalized Older Adults With Acute Heart Failure Exacerbation.

BACKGROUND: Delirium among older adults hospitalized with acute heart failure is associated with increased mortality. However, studies concomitantly assessing the association of delirium with both clinical and economic outcomes in this population, such as mortality, hospital cost, or length of stay, are lacking. METHODS AND RESULTS: We conducted a retrospective observational study using National Inpatient Sample data from 2011 to 2014. Using multivariable logistic regression, we assessed the association of delirium with in-hospital mortality, then estimated the incremental hospital cost and excessive length of stay adjusting for demographic and clinical factors using multivariable generalized linear regression. The association of other medical complications on clinical and economic outcomes was also assessed. A total of 568,565 (weighted N = 2,826,131) hospitalizations of patients 65 years or older with acute heart failure from 2011 to 2014 were included in the final analysis. The reported prevalence of delirium was 4.53%. After multivariable adjustment, delirium was associated with a 2.35-fold increase in the odds of in-hospital mortality (95% confidence interval [CI] 2.23-2.47), which was lower than the odds ratio for sepsis/septicemia (5.36; 95% CI, 5.02-5.72) or respiratory failure (4.53; 95% CI, 4.38-4.69), but similar to that for acute kidney injury (2.39; 95% CI, 2.31-2.48) and higher than for non-ST elevation myocardial infarct (1.57; 95% CI, 1.46-1.68). Delirium increased the total hospital cost by $4,262 (95% CI, $4,002-4,521) and the length of stay by 1.73 days (95% CI, 1.68-1.78), which was slightly lower than, but similar to, acute kidney injury ($4,771; 95% CI, $4,644-4,897) and 1.82 days (95% CI, 1.79-1.84), and higher than non-ST elevation myocardial infarct ($1,907; 95% CI, $1,629-2,185) and 0.31 days (95% CI, 0.25-0.37). CONCLUSIONS: Delirium was associated with increased in-hospital mortality, total hospital cost, and length of stay, and the magnitude of the effect was similar to that for acute kidney injury. Enhanced efforts to prevent delirium are needed to decrease its adverse impact on clinical and economic outcomes for hospitalized older adults with acute heart failure.

Quality and Cost of Care by Hospital Teaching Status: What Are the Differences?

Policy Points In two respects, quality of care tends to be higher at major teaching hospitals: process of care and long-term survival of cancer patients following initial diagnosis. There is also evidence that short-term (30-day) mortality is lower on average at such hospitals, although the quality of evidence is somewhat lower. Quality of care is mulitdimensional. Empirical evidence by teaching status on dimensions other than survival is mixed. Higher Medicare payments for care provided by major teaching hospitals are partially offset by lower payments to nonhospital providers. Nevertheless, the payment differences between major teaching and nonteaching hospitals for hospital stays, especially for complex cases, potentially increase prices other insurers pay for hospital care. CONTEXT: The relative performance of teaching hospitals has been discussed for decades. For private and public insurers with provider networks, an issue is whether having a major teaching hospital in the network is a "must." For traditional fee-for-service Medicare, there is an issue of adequacy of payment of hospitals with various attributes, including graduate medical education (GME) provision. Much empirical evidence on relative quality and cost has been published. This paper aims to (1) evaluate empirical evidence on relative quality and cost of teaching hospitals and (2) assess what the findings indicate for public and private insurer policy. METHODS: Complementary approaches were used to select studies for review. (1) Relevant studies highly cited in Web of Science were selected. (2) This search led to studies cited by these studies as well as studies that cited these studies. (3) Several literature reviews were helpful in locating pertinent studies. Some policy-oriented papers were found in Google under topics to which the policy applied. (4) Several papers were added based on suggestions of reviewers. FINDINGS: Quality of care as measured in process of care studies and in longitudinal studies of long-term survival of cancer patients tends to be higher at major teaching hospitals. Evidence on survival at 30 days post admission for common conditions and procedures also tends to favor such hospitals. Findings on other dimensions of relative quality are mixed. Hospitals with a substantial commitment to graduate medical education, major teaching hospitals, are about 10% to 20% more costly than nonteaching hospitals. Private insurers pay a differential to major teaching hospitals at this range's lower end. Inclusive of subsidies, Medicare pays major teaching hospitals substantially more than 20% extra, especially for complex surgical procedures. CONCLUSIONS: Based on the evidence on quality, there is reason for patients to be willing to pay more for inclusion of major teaching hospitals in private insurer networks at least for some services. Medicare payment for GME has long been a controversial policy issue. The actual indirect cost of GME is likely to be far less than the amount Medicare is currently paying hospitals.

Sentinel lymph node biopsy is associated with increased cost in higher risk thin melanoma.

INTRODUCTION: National Comprehensive Cancer Network guidelines recommend that sentinel lymph node biopsy (SLNB) be discussed with patients with thin melanoma at higher risk for lymph node metastasis (T1b or T1a with positive deep margins, lymphovascular invasion, or high mitotic index). We examined the association between SLNB and resource utilization in this cohort. METHODS: We conducted a retrospective cohort study of patients that underwent wide local excision for higher risk thin melanomas from 2009 to 2018 at a tertiary care center. Patients who underwent SLNB were compared to those who did not undergo SLNB with regard to resource utilization, including total hospital cost. RESULTS: A total of 70 patients were included in the analysis and 50 patients (71.4%) underwent SLNB. SLNB was associated with increased hospital costs ($6700 vs. $3767; p < .01) and increased operative time (68.5 vs. 36.0 min; p < .01). This cost difference persisted in multivariable regression (p < .01). Of patients who underwent successful SLN mapping, 3 out of 49 patients had a positive SLN (6.1%). The cost to identify a single positive sentinel lymph node (SLN) was $47,906. CONCLUSION: In patients with a higher risk of thin melanoma, SLNB is associated with increased cost despite a low likelihood of SLN positivity. These data better inform patient-provider discussions as the role of SLNB in thin melanoma evolves.

Extubation in the Operating Room After Transapical Transcatheter Aortic Valve Implantation Safely Improves Time-Related Outcomes and Lowers Costs: A Propensity Score-Matched Analysis.

OBJECTIVE: The experience of safe extubation in the operating room (OR) after transcatheter aortic valve implantation (TAVI) procedure remains not well established. The authors conducted this study to assess the effect of OR extubation in comparison with extubation in the intensive care unit (ICU) on the outcomes and cost in patients undergoing transapical-TAVI. DESIGN: A propensity score-matched analysis. SETTING: A single major urban teaching and university hospital. PARTICIPANTS: A total of 266 patients undergoing transapical TAVI under general anesthesia between June 2015 and March 2020. INTERVENTIONS: Propensity matching on pre- and intraoperative variables was used to identify 99 patients undergoing extubation in the OR versus 72 undergoing extubation in the ICU for outcome analysis. MEASUREMENTS AND MAIN RESULTS: After matching, extubation in the OR showed significant reductions of length of stay (LOS) in ICU (38.8 ± 17.4 v 58.0 ± 70.0 h, difference -19.2, 95% confidence interval [CI] -35.7 to -2.7, p = 0.009) and postoperative LOS in hospital (7.1 ± 3.9 v 10.1 ± 4.6 d, difference -3.0, 95% CI -4.3 to -1.7, p < 0.0001) compared with ICU extubation, but did not significantly affect the composite incidence of any postoperative complications (46.5% [46 of 99] v 52.8% [38 of 72], difference -6.3%, 95% CI -21.5 to 8.9, p = 0.415). Also, extubation in the OR led to significant reduction of total hospital cost compared with extubation in the ICU (¥303.5 ± 17.3 v ¥329.9 ± 52.3 thousand, difference -26.2, 95% CI -38.8 to -13.7, p < 0.0001). CONCLUSIONS: The current study provided evidence that extubation in the OR could be performed safely without increases in morbidity, mortality, or reintubation rate and could provide cost-effective outcome benefits in patients undergoing transapical-TAVI.

Analysis of Characteristics and Mortality in Cardiac Arrest Patients by Hospital Level: a Nationwide Population-based Study.

BACKGROUND: Survival and post-cardiac arrest care vary considerably by hospital, region, and country. In the current study, we aimed to analyze mortality in patients who underwent cardiac arrest by hospital level, and to reveal differences in patient characteristics and hospital factors, including post-cardiac arrest care, hospital costs, and adherence to changes in resuscitation guidelines. METHODS: We enrolled adult patients (≥ 20 years) who suffered non-traumatic cardiac arrest from 2006 to 2015. Patient demographics, insurance type, admission route, comorbidities, treatments, and hospital costs were extracted from the National Health Insurance Service database. We categorized patients into tertiary hospital, general hospital, and hospital groups according to the level of the hospital where they were treated. We analyzed the patients' characteristics, hospital factors, and mortalities among the three groups. We also analyzed post-cardiac arrest care before and after the 2010 guideline changes. The primary end-point was 30 days and 1 year mortality rates. RESULTS: The tertiary hospital, general hospital, and hospital groups represented 32.6%, 49.6%, and 17.8% of 337,042 patients, respectively. The tertiary and general hospital groups were younger, had a lower proportion of medical aid coverage, and fewer comorbidities, compared to the hospital group. Post-cardiac arrest care, such as percutaneous coronary intervention, targeted temperature management, and extracorporeal membrane oxygenation, were provided more frequently in the tertiary and general hospital groups. After adjusting for age, sex, insurance type, urbanization level, admission route, comorbidities, defibrillation, resuscitation medications, angiography, and guideline changes, the tertiary and general hospital groups showed lower 1-year mortality (tertiary hospital vs. general hospital vs. hospital, adjusted odds ratios, 0.538 vs. 0.604 vs. 1; P < 0.001). After 2010 guideline changes, a marked decline in atropine use and an increase in post-cardiac arrest care were observed in the tertiary and general hospital groups. CONCLUSION: The tertiary and general hospital groups showed lower 30 days and 1 year mortality rates than the hospital group, after adjusting for patient characteristics and hospital factors. Higher-level hospitals provided more post-cardiac arrest care, which led to high hospital costs, and showed good adherence to the guideline change after 2010.

The impact of medical interventions on admission characteristics in children with congenital heart disease and cardiomyopathy.

INTRODUCTION: Children with congenital heart disease and cardiomyopathy are a unique patient population. Different therapies continue to be introduced with large practice variability and questionable outcomes. The purpose of this study is to determine the impact of various medications on intensive care unit length of stay, total length of stay, billed charges, and mortality for admissions with congenital heart disease and cardiomyopathy. MATERIALS AND METHODS: We identified admissions of paediatric patients with cardiomyopathy using the Pediatric Health Information System database. The admissions were then separated into two groups: those with and without inpatient mortality. Univariate analyses were conducted between the groups and the significant variables were entered as independent variables into the regression analyses. RESULTS: A total of 10,376 admissions were included these analyses. Of these, 904 (8.7%) experienced mortality. Comparing patients who experienced mortality with those who did not, there was increased rate of acute kidney injury with an odds ratio (OR) of 5.0 [95% confidence interval (CI) 4.3 to 5.8, p < 0.01], cardiac arrest with an OR 7.5 (95% CI 6.3 to 9.0, p < 0.01), and heart transplant with an OR 0.3 (95% CI 0.2 to 0.4, p < 0.01). The medical interventions with benefit for all endpoints after multivariate regression analyses in this cohort are methylprednisolone, captopril, enalapril, furosemide, and amlodipine. CONCLUSIONS: Diuretics, steroids, angiotensin-converting enzyme inhibitors, calcium channel blockers, and beta blockers all appear to offer beneficial effects in paediatric cardiomyopathy admission outcomes. Specific agents within each group have varying effects.

Factors affecting in-hospital cost and mortality of patients with stroke: Evidence from a case study in a tertiary hospital in China.

OBJECTIVE: The study aims to investigate the factors causing the difference of stroke patients' in-hospital cost and study these factors on health outcome in terms of mortality. METHODS: Eight hundred and sixty-two in-patients with stroke in a tertiary hospital in China from 2017 to 2019 were included in the database. Descriptive statistics indexes were used to describe patients' in-hospital cost and mortality. Based on Elixhauser coding algorithms, multiple linear regression and logistic regressions (LRs) were used to evaluate the impact of factors identified from univariate analysis on in-hospital cost and mortality, respectively. In addition to LRs, a comparison study was then carried out with random forest, gradient boosting decision tree and artificial neural network. RESULTS: Factors affecting both cost and mortality are age, discharged day-of-week, length of stay, stroke subtype, other neurological disorders, renal failure, fluid and electrolyte disorders and total number of comorbidities. CONCLUSION: With the increase of age, the mortality rate of in-patients (except for the juvenile) with stroke increases and the cost of hospitalization decreases. Intracerebral haemorrhage is the most devastating stroke for its highest mortality in short length of stay. Medical services should focus on these specific comorbidities.
