Year 1 of the Bundled Payments for Care Improvement-Advanced Model.

BACKGROUND: The Center for Medicare and Medicaid Innovation launched the Medicare Bundled Payments for Care Improvement-Advanced (BPCI-A) program for hospitals in October 2018. Information is needed about the effects of the program on health care utilization and Medicare payments. METHODS: We conducted a modified segmented regression analysis using Medicare claims and including patients with discharge dates from January 2017 through September 2019 to assess differences between BPCI-A participants and two control groups: hospitals that never joined the BPCI-A program (nonjoining hospitals) and hospitals that joined the BPCI-A program in January 2020, after the conclusion of the intervention period (late-joining hospitals). The primary outcomes were the differences in changes in quarterly trends in 90-day per-episode Medicare payments and the percentage of patients with readmission within 90 days after discharge. Secondary outcomes were mortality, volume, and case mix. RESULTS: A total of 826 BPCI-A participant hospitals were compared with 2016 nonjoining hospitals and 334 late-joining hospitals. Among BPCI-A hospitals, the mean baseline 90-day per-episode Medicare payment was $27,315; the change in the quarterly trends in the intervention period as compared with baseline was -$78 per quarter. Among nonjoining hospitals, the mean baseline 90-day per-episode Medicare payment was $25,994; the change in quarterly trends as compared with baseline was -$26 per quarter (difference between nonjoining hospitals and BPCI-A hospitals, $52 [95% confidence interval {CI}, 34 to 70] per quarter; P<0.001; 0.2% of the baseline payment). Among late-joining hospitals, the mean baseline 90-day per-episode Medicare payment was $26,807; the change in the quarterly trends as compared with baseline was $4 per quarter (difference between late-joining hospitals and BPCI-A hospitals, $82 [95% CI, 41 to 122] per quarter; P<0.001; 0.3% of the baseline payment). There were no meaningful differences in the changes with regard to readmission, mortality, volume, or case mix. CONCLUSIONS: The BPCI-A program was associated with small reductions in Medicare payments among participating hospitals as compared with control hospitals.

Call for Action to Target Interhospital Variation in Cardiovascular Mortality, Readmissions, and Length-of-Stay: Results of a National Population Analysis.

BACKGROUND: Excessive interhospital variation threatens healthcare quality. Data on variation in patient outcomes across the whole cardiovascular spectrum are lacking. We aimed to examine interhospital variability for 28 cardiovascular All Patient Refined-Diagnosis-related Groups (APR-DRGs). METHODS: We studied 103,299 cardiovascular admissions in 99 (98%) Belgian acute-care hospitals between 2012 and 2018. Using generalized linear mixed models, we estimated hospital-specific and APR-DRG-specific risk-standardized rates for in-hospital mortality, 30-day readmissions, and length-of-stay above the APR-DRG-specific 90th percentile. Interhospital variation was assessed based on estimated variance components and time trends between the 2012-2014 and 2016-2018 periods were examined. RESULTS: There was strong evidence of interhospital variation, with statistically significant variation across the 3 outcomes for 5 APR-DRGs after accounting for patient and hospital factors: percutaneous cardiovascular procedures with acute myocardial infarction, heart failure, hypertension, angina pectoris, and arrhythmia. Medical diagnoses, with in particular hypertension, heart failure, angina pectoris, and cardiac arrest, showed strongest variability, with hypertension displaying the largest median odds ratio for mortality (2.51). Overall, hospitals performing at the upper-quartile level should achieve improvements to the median level, and an annual 633 deaths, 322 readmissions, and 1578 extended hospital stays could potentially be avoided. CONCLUSIONS: Analysis of interhospital variation highlights important outcome differences that are not explained by known patient or hospital characteristics. Targeting variation is therefore a promising strategy to improve cardiovascular care. Considering their treatment in multidisciplinary teams, policy makers, and managers should prioritize heart failure, hypertension, cardiac arrest, and angina pectoris improvements by targeting guideline implementation outside the cardiology department.

An analysis of a rural hospital's investment decision under different payment systems.

From an economic perspective, large investments in medical equipment are justifiable only when many patients benefit. Although rural hospitals play a crucial role locally, the treatments they can offer are limited. In this study, I characterize investment level that maximizes the total surplus, encompassing patients' welfare and producer surplus, and subtracting treatment costs. Specifically, I account for economic externalities generated by the investment in the rural hospital and for different utility losses that patients suffer when they cannot be treated locally. I demonstrate that the optimal investment level can be implemented if the Health Authority has the power to set specific prices for each disease. Additionally, I explore a decentralized situation wherein the investment decision lies with the rural hospital manager, and the Health Authority can only make a discrete decision between two payment systems: Fee-for-service, which covers all treatment costs, or Diagnosis-Related-Groups, which reimburses a price per patient based on the overall average cost. I find that the Diagnosis-Related-Groups system outperforms the Fee-for-service in terms of total surplus when the treatment cost at the rural hospital is lower. However, when the rural hospital has higher costs and the Health Authority seeks to incentivize investment, the Fee-for-service system is superior.

How do hospitals respond to payment unbundling for diagnostic imaging of suspected cancer patients?

Payments for some diagnostic scans undertaken in outpatient settings were unbundled from Diagnosis Related Group based payments in England in April 2013 to address under-provision. Unbundled scans attracted additional payments of between £45 and £748 directly following the reform. We examined the effect on utilization of these scans for patients with suspected cancer. We also explored whether any detected effects represented real increases in use of scans or better coding of activity. We applied difference-in-differences regression to patient-level data from Hospital Episodes Statistics for 180 NHS hospital Trusts in England, between April 2010 and March 2018. We also explored heterogeneity in recorded use of scans before and after the unbundling at hospital Trust-level. Use of scans increased by 0.137 scans per patient following unbundling, a 134% relative increase. This increased annual national provider payments by £79.2 million. Over 15% of scans recorded after the unbundling were at providers that previously recorded no scans, suggesting some of the observed increase in activity reflected previous under-coding. Hospitals recorded substantial increases in diagnostic imaging for suspected cancer in response to payment unbundling. Results suggest that the reform also encouraged improvements in recording, so the real increase in testing is likely lower than detected.

Exploring hot topics and evolutionary paths in the Diagnosis-Related Groups (DRGs) field: a comparative study using LDA modeling.

BACKGROUND: This study reviews the research status of Diagnosis-related groups (DRGs) payment system in China and globally by analyzing topical issues in this field and exploring the evolutionary trends of DRGs in different developmental stages. METHODS: Abstracts of relevant literature in the field of DRGs were extracted from the China National Knowledge Infrastructure (CNKI) database and the Web of Science (WoS) core database and used as text data. A probabilistic distribution-based Latent Dirichlet Allocation (LDA) topic model was applied to mine the text topics. Topical issues were determined by topic intensity, and the cosine similarity of the topics in adjacent stages was calculated to analyze the topic evolution trend. RESULTS: A total of 6,758 English articles and 3,321 Chinese articles were included. Foreign research on DRGs focuses on grouping optimization, implementation effects, and influencing factors, whereas research topics in China focus on grouping and payment mechanism establishment, medical cost change evaluation, medical quality control, and performance management reform exploration. CONCLUSIONS: Currently, the field of DRGs in China is developing rapidly and attracting deepening research. However, the implementation depth of research in China remains insufficient compared with the in-depth research conducted abroad.

The role of human capital and stress for cost awareness in the healthcare system: a survey among German hospital physicians.

BACKGROUND: Germany has the highest per capita health care spending among EU member states, but its hospitals face pressure to generate profits independently due to the government's withdrawal of investment cost coverage. The diagnosis related groups (DRG) payment system was implemented to address the cost issue, challenging hospital physicians to provide services within predefined prices and an economic target corridor to reduce costs. This study examines the extent of cost awareness among medical personnel in German hospitals and its influencing factors. METHODS: We developed an online survey in which participants across all specialties in hospitals estimated the prices in euros of four common interventions and answered questions about their human capital and perceived stress on the workplace. As a measure of cost awareness, we used the probability of estimating the prices correctly within a reasonable margin. We employed logit logistic regression estimators to identify influencing factors in a sample of 86 participants. RESULTS: The results revealed that most of the respondents were unaware of the costs of common interventions. General human capital, acquired through prior education, and job-specific human capital had no influence on cost awareness, whereas domain-specific human capital, that is, gaining economic knowledge based on self-interest, had a positive nonlinear effect on cost awareness. Furthermore, an increased stress level negatively influenced cost awareness. CONCLUSIONS: This paper is the first of its kind for the German health care sector that contributes responses to the question whether health care professionals in German hospitals have cost awareness and if not, what reasons lie behind this lack of knowledge. Our findings show that the cost awareness desired by the introduction of the DRG system has yet to be achieved by medical personnel.

Impact of early death recording on international comparison of acute myocardial infarction mortality - administrative hospital data study using the example of Germany and the United States.

BACKGROUND: In-hospital mortality from acute myocardial infarction (AMI) is widely used in international comparisons as an indicator of health system performance. Because of the high risk of early death after AMI, international comparisons may be biased by differences in the recording of early death cases in hospital inpatient data. This study examined whether differences in the recording of early deaths affect international comparisons of AMI in-hospital mortality by using the example of Germany and the United States, and explored approaches to address this issue. METHODS: The German Diagnosis-Related Groups Statistics (DRG Statistics), the U.S. National Inpatient Sample (NIS) and the U.S. Nationwide Emergency Department Sample (NEDS) were analysed from 2014 to 2019. Cases with treatment for AMI were identified in German and U.S. inpatient data. AMI deaths occurring in the emergency department (ED) without inpatient admission were extracted from NEDS data. 30-day in-hospital mortality figures were calculated according to the OECD indicator definition (unlinked data) and modified by including ED deaths, or excluding all same-day cases. RESULTS: German age-and-sex standardized 30-day in-hospital mortality was substantially higher compared to the U.S. (in 2019, 7.3% vs. 4.6%). The ratio of German vs. U.S. mortality was 1.6. After inclusion of ED deaths in U.S. data this ratio declined to 1.4. Exclusion of same-day cases in German and U.S. data led to a similar ratio. CONCLUSIONS: While short-duration treatments due to early death are generally recorded in German inpatient data, in U.S. inpatient data those cases are partially missing. Excluding cases with short-duration treatment from the calculation of mortality indicators could be a feasible approach to account for differences in the recording of early deaths, that might be existent in other countries as well.

Lower comorbidity scores and severity levels in Veterans Health Administration hospitals: a cross-sectional study.

BACKGROUND: Previous studies found that documentation of comorbidities differed when Veterans received care within versus outside Veterans Health Administration (VHA). Changes to medical center funding, increased attention to performance reporting, and expansion of Clinical Documentation Improvement programs, however, may have caused coding in VHA to change. METHODS: Using repeated cross-sectional data, we compared Elixhauser-van Walraven scores and Medicare Severity Diagnosis Related Group (DRG) severity levels for Veterans' admissions across settings and payers over time, utilizing a linkage of VHA and all-payer discharge data for 2012-2017 in seven US states. To minimize selection bias, we analyzed records for Veterans admitted to both VHA and non-VHA hospitals in the same year. Using generalized linear models, we adjusted for patient and hospital characteristics. RESULTS: Following adjustment, VHA admissions consistently had the lowest predicted mean comorbidity scores (4.44 (95% CI 4.34-4.55)) and lowest probability of using the most severe DRG (22.1% (95% CI 21.4%-22.8%)). In contrast, Medicare-covered admissions had the highest predicted mean comorbidity score (5.71 (95% CI 5.56-5.85)) and highest probability of using the top DRG (35.3% (95% CI 34.2%-36.4%)). CONCLUSIONS: More effective strategies may be needed to improve VHA documentation, and current risk-adjusted comparisons should account for differences in coding intensity.

Validation of a Costing Algorithm and Cost Drivers for Neonates Admitted to the Neonatal Intensive Care Unit.

OBJECTIVE: Neonatal intensive care units (NICUs) account for over 35% of pediatric in-hospital costs. A better understanding of NICU expenditures may help identify areas of improvements. This study aimed to validate the Canadian Neonatal Network (CNN) costing algorithm for seven case-mix groups with actual costs incurred in a tertiary NICU and explore drivers of cost. STUDY DESIGN: A retrospective cohort study of infants admitted within 24 hours of birth to a Level-3 NICU from 2016 to 2019. Patient data and predicted costs were obtained from the CNN database and were compared to actual obtained from the hospital accounting system (Coût par Parcours de Soins et de Services). Cost estimates (adjusted to 2017 Canadian Dollars) were compared using Spearman correlation coefficient (rho). RESULTS: Among 1,795 infants included, 169 (9%) had major congenital anomalies, 164 (9%) with <29 weeks' gestational age (GA), 189 (11%) with 29 to 32 weeks' GA, and 452 (25%) with 33 to 36 weeks' GA. The rest were term infants: 86 (5%) with hypoxic-ischemic encephalopathy treated with therapeutic hypothermia, 194 (11%) requiring respiratory support, and 541 (30%) admitted for other reasons. Median total NICU costs varied from $6,267 (term infants admitted for other reasons) to $211,103 (infants born with <29 weeks' GA). Median daily costs ranged from $1,613 to $2,238. Predicted costs correlated with actual costs across all case-mix groups (rho range 0.78-0.98, p < 0.01) with physician and nursing representing the largest proportion of total costs (65-82%). CONCLUSION: The CNN algorithm accurately predicts NICU total costs for seven case-mix groups. Personnel costs account for three-fourths of in-hospital total costs of all infants in the NICU. KEY POINTS: · Very preterm infants born below 33 weeks of gestation account for most of NICU resource use.. · Human resources providing direct patient care represented the largest portion of costs.. · The algorithm strongly predicted total costs for all case-mix groups..

[Impact Analysis of a new, Cross-sector Service Provision of Gastroenterologic Endoscopic Services in Accordance with 115f SGB V (Hybrid-DRG): Allocation Matrix and Cost Analysis]. / Auswirkungsanalyse einer neuen, sektorenübergreifenden Erbringung bisher stationärer endoskopischer gastroenterologischer Leistungen entsprechend §115f SGB V (Hybrid-DRG): Zuordnungsmatrix und Kostenanalyse.

BACKGROUND: With the introduction of §115f SGB V, the prerequisites for "sector-equal remuneration" ('Hybrid DRG') have been created. In an impact analysis, we assigned inpatient gastroenterological endoscopic (GAEN) cases in a matrix of future hybrid DRG versus outpatient surgery (AOP) or inpatient treatment. METHODS: In selected DRGs (G47B, G67A, G67B, G67C, G71Z, H41D, H41E) an allocation matrix of GAEN cases was created on medical grounds. For this purpose, service groups from the DGVS service catalog ('Leistungskatalog') were assigned to the groups: 'Hybrid-DRG', 'AOP' and 'Inpatient' by a group of experts based on the DGVS position paper. Cost data from the DGVS-DRG project for the 2022 data year from 36 InEK calculation hospitals with a total of 232,476 GAEN cases were evaluated. RESULTS: 26 service groups from the DGVS service catalog were assigned to a "Hybrid-DRG", 24 to the "inpatient" group, and 12 to the "AOP" group. 7 performance groups were splitted "depending on the OPS code" and classified at this level. Cases with additional fees were excluded from a hybrid DRG because these cannot be agreed there.The cost analysis shows that services that are already in the AOP have a similar cost level to services that have been classified as 'Hybrid-DRG'. With the cost calculation, a cost level could be presented for the hybrid DRGs formed. CONCLUSION: Based on clearly defined structural, procedural and personnel requirements, services from suitable DRGs can be transferred to a hybrid DRG. Assigning services without the involvement of clinical experts seems extremely difficult. Case assignment based on arbitrary contextual factors increases complexity without demonstrably increasing the quality of the assignment and needs to be further developed. A cost analysis can be derived from the known inpatient costs and must serve as the basis for the 2025 Hybrid DRG catalog.

[A critical DRG-evaluation of cases with inflammatory bowel disease]. / Ein kritischer DRG-Blick auf Fälle mit chronisch entzündlichen Darmerkrankungen.

INTRODUCTION: Whether inpatients with inflammatory bowel disease (IBD) are reimbursed in a cost-covering manner in German hospitals has not yet been investigated. In this context, the present study analyses the reimbursement situation (cost-revenue comparison) of IBD in German hospitals with regard to the complexity of the disease and the type of care. METHODS: For this retrospective study, anonymized case data, including cost data from the InEK calculation (§ 21-4 KHEntgG) of the DRG project of the German Society for Gastroenterology, Digestive and Metabolic Diseases (DGVS) from 2019, were available. 3385 cases with IBD the as main diagnosis from 49 hospitals were analyzed. To investigate the impact of disease complexity on reimbursement, different variables were analyzed, including gastroenterological complications, infections, the reason for admission, and additional charges. To investigate possible center effects, hospitals were grouped by type of care, mostly defined by the number of beds. RESULTS: The present study shows that all types of care can be classified as not cost-covering on average. The under-recovery is, on average, 10% (296 € absolute under-recovery) and varies between the types of care. Cases with higher complexity show a higher cost under-recovery than cases with lower complexity. At the DRG level, the analyzed costs of the three most common IBD DRGs for inlier patients are higher than the InEK costs; however, the difference is not significant. Nonetheless, cases with the admission reason transfer of specific DRGs bear significantly higher costs. DISCUSSION: Our results show that CED is not reimbursed in a cost-covering manner. This is due to inadequate reimbursement for gastroenterological complications, infections, specific procedures, and emergency and transfer cases. Transfer cases bear significantly higher costs.

How does diagnosis-related group payment impact the health care received by rural residents? Lessons learned from China.

OBJECTIVES: There is growing evidence that differences exist between rural and urban residents in terms of health, access to care and the quality of health care received, especially in low- and middle-income countries (LMICs). To improve health equity and the performance of health systems, a diagnosis-related group (DRG) payment system has been introduced in many LMICs to reduce financial risk and improve the quality of health care. The aim of this study was to examine the impact of DRG payments on the health care received by rural residents in China, and to help policymakers identify and design implementation strategies for DRG payment systems for rural residents in LMICs. STUDY DESIGN: Health impact assessment. METHODS: This study compared the impact of DRG payments on the healthcare received by rural residents in China between the pre- and post-reform periods by applying a difference-in-difference (DID) methodology. The study population included individuals with three common conditions; namely, cerebral infarction, transient ischaemic attack (TIA), and vertebrobasilar insufficiency (VBI). Data on patient medical insurance type were assessed, and those who did not have rural insurance were excluded. RESULTS: This study included 13,088 patients. In total, 33.63% were from Guangdong (n = 4401), 38.21% were from Shandong (n = 5002), and 28.16% were from Guangxi (n = 3685). The DID results showed that the implementation of DRGs was positively associated with hospitalization expense (ß4 = 0.265, P = 0.000), treatment expense (ß4 = 0.343, P = 0.002), drug expense (ß4 = 0.607, P = 0.000), the spending of medical insurance funds (ß4 = 0.711, P = 0.000) and out-of-pocket costs (ß4 = 0.164, P = 0.000). CONCLUSIONS: The findings of this study suggest that the implementation of DRG payments increases health care costs and the financial burden on health systems and rural patients in LMICs. This is contrary to the original intention of implementing the DRG payment system.

Rising incidence of severe maxillofacial space infections in Germany.

OBJECTIVES: Severe maxillofacial space infection (MSI) as an end stage of dentoalveolar diseases or complication of sialadenitis is a potentially life-threatening disease accompanied by complications including airway obstruction, jugular vein thrombosis, descending mediastinitis, sepsis and acute respiratory distress syndrome. The aim of this study was to analyze the incidence and time trends of severe MSI and potentially influencing factors in the German healthcare system over time. MATERIALS AND METHODS: Nationwide data regarding the national diagnosis-related-group (DRG) inpatient billing system was received from the German Federal Statistical Office. A retrospective analysis of incidence and time trends of MSI-associated procedures classified with the Operation and Procedure Classification System (OPS), were statistically evaluated using Poisson regression analysis between 2005 and 2022 and were associated with different epidemiological factors. RESULTS: The total standardized incidence rate of MSI-associated procedures in the observational period 2005-2022 was 9.8 (♀8.2; ♂11.4) per 100,000 person years. For all age groups a significant increase of 46.1% in severe MSI - related surgical interventions was registered within the observational period. The largest increase (120.5%) was found in elderly patients over 80 years. There were significant differences of the incidences of MSI-associated surgeries between the different federal states in Germany. CONCLUSIONS: Severe MSI are a growing challenge in German health care especially among elderly patients over 80 years. CLINICAL RELEVANCE: Severe MSI is a promising target for prevention. There should be more focus in primary dental and medical care especially in groups depending on social support.

Impacts of a new diagnosis-related group point payment system on children's medical services in China: Length of stay and costs.

BACKGROUND: Paediatric healthcare is always highlighted in medical and health care system reform in China. Zhejiang Province established a new diagnosis-related group (DRG) point payment reform in 2020 to regulate provider behaviours and control medical costs. We conducted this study to evaluate impacts of the DRG point payment policy on provider behaviours and resource usage in children's medical services. METHODS: Data from patients' discharge records from July 2019 to December 2020 in Children's Hospital, Zhejiang University School of Medicine were collected for analysis. We employed the interrupted time series approach to reveal the trend before and after the DRG point payment reform and the difference-in-differences analysis to estimate the independent outcome changes attributed to the reform. RESULTS: We found that the upward trend of length of stay slightly slowed, and the total costs began to decrease at the post-policy stage. Although independent effects of the reform were not presented among the whole sample, the length of stay and hospitalisation costs of moderate-hospital-stay paediatric patients, non-surgical patients, and infant patients were found to decrease rapidly after the reform. CONCLUSION: DRG point payments can changed the provider behaviours and eventually reduce healthcare resource usage in children's medical services.

Health Equity Adjustment and Hospital Performance in the Medicare Value-Based Purchasing Program.

Importance: Medicare's Hospital Value-Based Purchasing (HVBP) program will provide a health equity adjustment (HEA) to hospitals that have greater proportions of patients dually eligible for Medicare and Medicaid and that offer high-quality care beginning in fiscal year 2026. However, which hospitals will benefit most from this policy change and to what extent are unknown. Objective: To estimate potential changes in hospital performance after HEA and examine hospital patient mix, structural, and geographic characteristics associated with receipt of increased payments. Design, Setting, and Participants: This cross-sectional study analyzed all 2676 hospitals participating in the HVBP program in fiscal year 2021. Publicly available data on program performance and hospital characteristics were linked to Medicare claims data on all inpatient stays for dual-eligible beneficiaries at each hospital to calculate HEA points and HVBP payment adjustments. Exposures: Hospital Value-Based Purchasing program HEA. Main Outcomes and Measures: Reclassification of HVBP bonus or penalty status and changes in payment adjustments across hospital characteristics. Results: Of 2676 hospitals participating in the HVBP program in fiscal year 2021, 1470 (54.9%) received bonuses and 1206 (45.1%) received penalties. After HEA, 102 hospitals (6.9%) were reclassified from bonus to penalty status, whereas 119 (9.9%) were reclassified from penalty to bonus status. At the hospital level, mean (SD) HVBP payment adjustments decreased by $4534 ($90 033) after HEA, ranging from a maximum reduction of $1 014 276 to a maximum increase of $1 523 765. At the aggregate level, net-positive changes in payment adjustments were largest among safety net hospitals ($28 971 708) and those caring for a higher proportion of Black patients ($15 468 445). The likelihood of experiencing increases in payment adjustments was significantly higher among safety net compared with non-safety net hospitals (574 of 683 [84.0%] vs 709 of 1993 [35.6%]; adjusted rate ratio [ARR], 2.04 [95% CI, 1.89-2.20]) and high-proportion Black hospitals compared with non-high-proportion Black hospitals (396 of 523 [75.7%] vs 887 of 2153 [41.2%]; ARR, 1.40 [95% CI, 1.29-1.51]). Rural hospitals (374 of 612 [61.1%] vs 909 of 2064 [44.0%]; ARR, 1.44 [95% CI, 1.30-1.58]), as well as those located in the South (598 of 1040 [57.5%] vs 192 of 439 [43.7%]; ARR, 1.25 [95% CI, 1.10-1.42]) and in Medicaid expansion states (801 of 1651 [48.5%] vs 482 of 1025 [47.0%]; ARR, 1.16 [95% CI, 1.06-1.28]), were also more likely to experience increased payment adjustments after HEA compared with their urban, Northeastern, and Medicaid nonexpansion state counterparts, respectively. Conclusions and Relevance: Medicare's implementation of HEA in the HVBP program will significantly reclassify hospital performance and redistribute program payments, with safety net and high-proportion Black hospitals benefiting most from this policy change. These findings suggest that HEA is an important strategy to ensure that value-based payment programs are more equitable.

Time trends in case-mix and risk of revision following hip and knee arthroplasty in public and private hospitals: a cross-sectional analysis based on 476,312 procedures from the Dutch Arthroplasty Register.

BACKGROUND AND PURPOSE: This study aims to assess time trends in case-mix and to evaluate the risk of revision and causes following primary THA, TKA, and UKA in private and public hospitals in the Netherlands. METHODS: We retrospectively analyzed 476,312 primary arthroplasties (public: n = 413,560 and private n = 62,752) implanted between 2014 and 2023 using Dutch Arthroplasty Register data. We explored patient demographics, procedure details, trends over time, and revisions per hospital type. Adjusted revision risk was calculated for comparable subgroups (ASA I/II, age ≤ 75, BMI ≤ 30, osteoarthritis diagnosis, and moderate-high socioeconomic status (SES). RESULTS: The volume of THAs and TKAs in private hospitals increased from 4% and 9% in 2014, to 18% and 21% in 2022. Patients in private hospitals were younger, had lower ASA classification, lower BMI, and higher SES compared with public hospital patients. In private hospitals, age and ASA II proportion increased over time. Multivariable Cox regression demonstrated a lower revision risk for primary THA (HR 0.7, CI 0.7-0.8), TKA (HR 0.8, CI 0.7-0.9), and UKA (HR 0.8, CI 0.7-0.9) in private hospitals. After initial arthroplasty in private hospitals, 49% of THA and 37% of TKA revisions were performed in public hospitals. CONCLUSION: Patients in private hospitals were younger, had lower ASA classification, lower BMI, and higher SES com-pared with public hospital patients. The number of arthroplasties increased in private hospitals, with a lower revision risk compared with public hospitals.

[Outpatient care in pulmonology - a scientific analysis and a position paper of the German Society of Respiratory Medicine (DGP)]. / Ambulantisierung in der Pneumologie ­ eine wissenschaftliche Analyse und ein Positionspapier der DGP.

INTRODUCTION: The ambulantization of patient care that were previously provided as inpatient service is one of the goals of the current reform in the German healthcare system. In pulmonology, this particularly applies to endoscopic procedures. However, the real costs of endoscopic services, which form the basis for the calculation of a future so called hybrid DRG or in the AOP catalog, are unclear. METHODS: After selection of use cases including endoscopic procedures which can be performed on an outpatient basis by a committee of experts the appropriate DRGs were identified from the §â€Š21-KHEntgG data for 2022 published by the Institute for the Hospital Remuneration System (InEK). The costs were calculated from the respective InEK cost matrix added by the calculated material costs. RESULTS: The use cases suitable for outpatient treatment were systematic endobronchial ultrasound (EBUS) with transbronchial needle aspiration (calculated costs €â€Š2,175.60 without or €â€Š3,315.60 including PET/CT), navigation-assisted bronchoscopy for peripheral lesions (depending on the methodology €â€Š2,870.23 to €4,120.23) and diagnostic (flexible) bronchoscopy (€â€Š1,121.02). CONCLUSION: Outpatient treatment of endoscopic procedures that were previously performed inpatient is possible and necessary, and the costs calculated in this publication can form a reliable basis for appropriate reimbursement. Together with a structural quality that has been transformed to outpatient service and cross-sector cooperation, continued high-quality care for pneumological patients can be ensured.

[Electrical dorsal root ganglion stimulation (DRGS) for the treatment of refractory postherpetic neuralgia]. / Elektricheskaya stimulyatsiya gangliya zadnikh koreshkov spinnogo mozga (DRGS) dlya lecheniya refrakternoi postgerpeticheskoi nevralgii.

Postherpetic neuralgia (PHN) is a rare complication of herpes zoster characterized by prolonged and excruciating pain. Traditional treatments for PHN, such as analgesics, anticonvulsants and antidepressants, do not always bring the desired result. One promising alternative that is attracting the attention of the scientific community is dorsal root ganglion stimulation (DRGS). This method focuses on targeted and precise targeting of the source of pain, providing a new level of effectiveness in the treatment of PHN. OBJECTIVE: A retrospective analysis of the technique and results of implantation of a permanent device for stimulating the spinal ganglia in patients with refractory PHN at the Burdenko Neurosurgical Center. MATERIAL AND METHODS: The study was conducted in 7 patients (5 men, 2 women) with refractory PHN in the period from 2018 to 2020. The age of the patients ranged from 57 to 84 years (average age 74±8.4). All patients were implanted with Boston systems (Precision or Spectra versions). Stimulation parameters: pulse width - 120-210 µs, frequency - 30-130 Hz, amplitude at the lower limit of the appearance of paresthesia with the possibility of increasing with increased pain up to 5 mA. The position of the electrode depended on the location of the pain. All systems were implanted under X-ray guidance. RESULTS: The duration of follow-up observation was more than 2.5 years. The average pain intensity one year after treatment was 3.42±2.45 points on the visual analogue scale (VAS) (a 62.3% decrease in intensity compared to baseline). In 3 (42.8%) patients, the result was characterized by us as «excellent¼ (intensity according to VAS decreased by 75% or more), in 1 (14.2%) - as «good¼ (intensity according to VAS decreased by 50-74%), in 1 (14.2%) - as «moderate¼ (VAS intensity decreased by 25-49% and in 2 (28.5%) as «unsatisfactory¼ (VAS intensity decreased by less than 25%, or postoperative complications occurred). CONCLUSION: Given the complicated nature of PHN, the use of dorsal ganglion stimulation appears to be a promising and innovative treatment approach. Further research is needed to introduce this technique into clinical practice for the treatment of patients suffering from PHN.

Professional Fees for U.S. Hospital Care, 2016-2020.

BACKGROUND: The latest comprehensive diagnosis-specific estimates of hospital professional fees relative to facility fees are from 2004 to 2012. OBJECTIVE: Update professional fee ratio (PFR) estimates to improve cost analysis opportunities with hospital discharge data sources and compare them with previous PFR estimates. SUBJECTS: 2016-2020 MarketScan inpatient admissions and emergency department (ED) treat and release claims. MEASURES: PFR was calculated as total admission or ED visit payment divided by facility-only payment. This measure can be multiplied by hospital facility costs to yield a total cost estimate. RESEARCH DESIGN: Generalized linear regression models controlling for selected patient and service characteristics were used to calculate adjusted mean PFR per admission or ED visit by health payer type (commercial or Medicaid) and by selected diagnostic categories representing all clinical diagnoses (Major Diagnostic Category, Diagnostic Related Group, and Clinical Classification Software Revised). RESULTS: Mean 2016-2020 PFR was 1.224 for admissions with commercial payers (n = 6.7 million admissions) and 1.178 for Medicaid (n = 4.2 million), indicating professional payments on average increased total payments by 22.4% and 17.8%, respectively, above facility-only payments. This is a 9% and 3% decline in PFR, respectively, compared with 2004 estimates. PFR for ED visits during 2016-2020 was 1.283 for commercial payers (n = 22.2 million visits) and 1.415 for Medicaid (n = 17.7 million). This is a 12% and 5% decline in PFR, respectively, compared with 2004 estimates. CONCLUSIONS: Professional fees comprise a declining proportion of hospital-based care costs. Adjustments for professional fees are recommended when hospital facility-only financial data are used to estimate hospital care costs.

Hospitals That Serve Many Black Patients Have Lower Revenues and Profits: Structural Racism in Hospital Financing.

BACKGROUND: Care for Black patients is concentrated at a relatively small proportion of all US hospitals. Some previous studies have documented quality deficits at Black-serving hospitals, which may be due to inequities in financial resources for care. OBJECTIVE: To assess disparities in funding between hospitals associated with the proportion of Black patients that they serve. PARTICIPANTS: All Medicare-participating hospitals, 2016-2018. MAIN MEASURES: Patient care revenues and profits per patient day at Black-serving hospitals (the top 10% of hospitals ranked by the share of Black patients among all Medicare inpatients) and at other hospitals, unadjusted and adjusted for differences in case mix and hospital characteristics. KEY RESULTS: Among the 574 Black-serving hospitals, an average of 43.7% of Medicare inpatients were Black, vs. 5.2% at the 5,166 other hospitals. Black-serving hospitals were slightly larger, and were more often urban, teaching, and for-profit or government (vs. non-profit) owned. Patient care revenues and profits averaged $1,736 and $-17 per patient day respectively at Black-serving hospitals vs. $2,213 and $126 per patient day at other hospitals (p<.001 for both comparisons). Adjusted for patient case mix and hospital characteristics, mean revenues were $283 lower/patient day (p<.001) and mean profits were $111/patient day lower (p<.001) at Black-serving hospitals. Equalizing reimbursement levels would have required $14 billion in additional payments to Black-serving hospitals in 2018, a mean of approximately $26 million per Black-serving hospital. CONCLUSIONS: US hospital financing effectively assigns a lower dollar value to the care of Black patients. To reduce disparities in care, health financing reforms should eliminate the underpayment of hospitals serving a large share of Black patients.
