Does the Design of Welfare Programs Stipulate Nursing Home Utilization? A Comparative Analysis of Long-Term Care Systems in Japan and Germany

Abstract Japan and Germany are both facing a rapidly aging population and have similar social insurance-based long-term care systems. However, there are significant differences in utilization and costs. This paper presents a microeconomic decision model validated by regression analysis, Blinder-Oaxaca decomposition, and Data Envelopment Analysis to contrast the utilization patterns in the Japanese and German long-term care sectors. The design of the welfare programs for low-income families has been identified as one of the main reasons. In Germany, the welfare system leads to a demand curve for nursing home care that is comparable to that of an inferior good which makes external long-term care in nursing homes the more attractive, the poorer the respective households are. In addition, the resulting inelastic demand of the population groups in need of social benefits seem to reduces competition among Germany’s long-term care providers, which is associated with a loss of efficiency in how they use production factors. In Japan, this negative outcome is avoided by a comfort segmentation in the nursing home market.

Assessing multidisciplinary follow-up pattern efficiency and cost in follow-up care for patients in cervical spondylosis surgery: a non-randomized controlled study.

The use of multidisciplinary treatment programs in out-of-hospital healthcare is a new area of research. Little is known about the benefits of this method in the management of discharged patients undergoing cervical spondylosis surgery. This study aimed to explore the effect of a contracted-based, multidisciplinary follow-up plan in patients after cervical spondylosis surgery. This non-blinded non-randomized controlled study was conducted with 88 patients (44 in the intervention group, 44 in the control group). The clinical outcomes, including Neck Disability Index (NDI), pain score (VAS), Self-Efficacy for Managing Chronic Disease 6-item Scale (SECD-6), and 12-Item Short-Form Health Survey (SF-12) score were assessed at the time of discharge, 24-72 h, 1 month, and 3 months post-discharge. The complications, patient satisfaction, and economic indicators were assessed at the final follow-up (3 months). Patients who received contracted follow-up showed greater improvement in neck dysfunction at 24-72 h, 1 month, and 3 months after discharge compared to those who received routine follow-up (p < 0.001). At 1 month after discharge, the intervention group exhibited better self-efficacy (p = 0.001) and quality of life (p < 0.001) than the control group, and these improvements lasted for 3 months. The intervention group reported lower pain scores at 24-72 h and 1 month (p = 0.008; p = 0.026) compared to the control group. The incidence of complications was significantly lower in the intervention group (11.4%) compared to the control group (40.9%). The total satisfaction score was significant difference between the two groups (p < 0.001). Additionally, the intervention group had lower direct medical costs (p < 0.001), direct non-medical costs (p = 0.035), and total costs (p = 0.04) compared to the control group. However, there was no statistically significant difference in indirect costs between the two groups (p = 0.59). A multidisciplinary contract follow-up plan has significant advantages regarding neck disability, self-efficacy, quality of life, postoperative complications, patient satisfaction, and direct costs compared with routine follow-up.

Is rapid acute coronary syndrome evaluation with high-sensitivity cardiac troponin less costly? An economic evaluation.

Protocols to evaluate for myocardial infarction (MI) using high-sensitivity cardiac troponin (hs-cTn) have the potential to drive costs upward due to the added sensitivity. We performed an economic evaluation of an accelerated protocol (AP) to evaluate for MI using hs-cTn to identify changes in costs of treatment and length of stay compared with conventional testing. We performed a planned secondary economic analysis of a large, cluster randomized trial across nine emergency departments (EDs) from July 2020 to April 2021. Patients were included if they were 18 years or older with clinical suspicion for MI. In the AP, patients could be discharged without further testing at 0h if they had a hs-cTnI<4ng/L and at 1h if the initial value were 4ng/L and the 1-h value ≤7ng/L. Patients in the standard of care (SC) protocol used conventional cTn testing at 0 and 3h. The primary outcome was the total cost of treatment, and the secondary outcome was ED length of stay. Among 32,450 included patients, an AP had no significant differences in cost (+$89, CI: -$714, $893 hospital cost, +$362, CI: -$414, $1138 health system cost) or ED length of stay (+46, CI: -28, 120min) compared with the SC protocol. In lower acuity, free-standing EDs, patients under the AP experienced shorter length of stay (-37min, CI: -62, 12min) and reduced health system cost (-$112, CI: -$250, $25). Overall, the implementation of AP using hs-cTn does not result in higher costs.

Is convenience really king? Comparative evaluation of catastrophic costs due to tuberculosis in the public and private healthcare sectors of Viet Nam: a longitudinal patient cost study

BackgroundIn Viet Nam, tuberculosis (TB) represents a devastating life-event with an exorbitant price tag, partly due to lost income from daily directly observed therapy in public sector care. Thus, persons with TB may seek care in the private sector for its flexibility, convenience, and privacy. Our study aimed to measure income changes, costs and catastrophic cost incurrence among TB-affected households in the public and private sector.MethodsBetween October 2020 and March 2022, we conducted 110 longitudinal patient cost interviews, among 50 patients privately treated for TB and 60 TB patients treated by the National TB Program (NTP) in Ha Noi, Hai Phong and Ho Chi Minh City, Viet Nam. Using a local adaptation of the WHO TB patient cost survey tool, participants were interviewed during the intensive phase, continuation phase and post-treatment. We compared income levels, direct and indirect treatment costs, catastrophic costs using Wilcoxon rank-sum and chi-squared tests and associated risk factors between the two cohorts using multivariate regression.ResultsThe pre-treatment median monthly household income was significantly higher in the private sector versus NTP cohort (USD 868 vs USD 578; P = 0.010). However, private sector treatment was also significantly costlier (USD 2075 vs USD 1313; P = 0.005), driven by direct medical costs which were 4.6 times higher than costs reported by NTP participants (USD 754 vs USD 164; P < 0.001). This resulted in no significant difference in catastrophic costs between the two cohorts (Private: 55% vs NTP: 52%; P = 0.675). Factors associated with catastrophic cost included being a single-person household [adjusted odds ratio (aOR = 13.71; 95% confidence interval (CI): 1.36–138.14; P = 0.026], unemployment during treatment (aOR = 10.86; 95% CI: 2.64–44.60; P < 0.001) and experiencing TB-related stigma (aOR = 37.90; 95% CI: 1.72–831.73; P = 0.021).ConclusionsPersons with TB in Viet Nam face similarly high risk of catastrophic costs whether treated in the public or private sector. Patient costs could be reduced through expanded insurance reimbursement to minimize direct medical costs in the private sector, use of remote monitoring and multi-week/month dosing strategies to avert economic costs in the public sector and greater access to social protection mechanism in general.

COMPARATIVE ANALYSIS OF COSTS AND RETURNS ACROSS FARM SIZES FOR SUGARCANE PRODUCTION IN MANDYA DISTRICT, KARNATAKA

The study examines the cost and returns of sugarcane cultivation across various farm sizes. The study indicates that the total cost of cultivation tends to vary across different farm sizes, with marginal farms incurring the lowest cost and large farms incurring the highest. It also highlights cost variations between main and ratoon crops, emphasizing labor, material, and power costs. Larger farms incur higher production costs but yield greater net returns, with ratoon crops generally more profitable. ANOVA analysis underscores significant differences in costs and returns among farmer categories. Despite the main crops higher productivity, lower returns compared to ratoon crops contribute to the latters continuity. The paper concludes that the profitability of the ratoon crop serves as a key incentive for continuing sugarcane cultivation despite the higher costs associated with the main crop. KEYWORDS: Sugarcane, Cost, Returns, Ratoon and Main crop

What is the Marginal Cost of Using Robot Assistance or Navigation for Transforaminal Lumbar Interbody Fusion? A Time-Driven Activity-Based Cost Analysis.

Our primary objective was to compare the marginal intraoperative cost of 3 different methods for pedicle screw placement as part of transforaminal lumbar interbody fusions (TLIFs). Specifically, we used time-driven activity-based costing to compare costs between robot-assisted TLIF (RA-TLIF), TLIF with intraoperative navigation (ION-TLIF), and freehand (non-navigated, nonrobotic) TLIF. Total cost was divided into direct and indirect costs. We identified all instances of RA-TLIF (n = 20), ION-TLIF (n = 59), and freehand TLIF (n = 233) from 2020 to 2022 at our institution. Software was developed to automate the extraction of all intraoperatively used personnel and material resources from the electronic medical record. Total costs were determined through a combination of direct observation, electronic medical record extraction, and interdepartmental collaboration (business operations, sterile processing, pharmacy, and plant operation departments). Multivariable linear regression analysis was performed to compare costs between TLIF modalities, accounting for patient-specific factors as well as number of levels fused, surgeon, and hospital site. The average total intraoperative cost per case for the RA-TLIF, ION-TLIF, and freehand TLIF cohorts was $24 838 ± $10 748, $15 991 ± $6254, and $14 498 ± $6580, respectively. Regression analysis revealed that RA-TLIF had significantly higher intraoperative cost compared with both ION-TLIF (β-coefficient: $7383 ± $1575, P < .001) and freehand TLIF (β-coefficient: $8182 ± $1523, P < .001). These cost differences were primarily driven by supply cost. However, there were no significant differences in intraoperative cost between ION-TLIF and freehand TLIF (P = .32). We demonstrate a novel use of time-driven activity-based costing methodology to compare different modalities for executing the same type of lumbar fusion procedure. RA-TLIF entails significantly higher supply cost when compared with other modalities, which explains its association with higher total intraoperative cost. The use of ION, however, does not add extra expense compared with freehand TLIF when accounting for confounders. This might have implications as surgeons and hospitals move toward bundled payments.

A study on the measurement of inter-provincial trade costs in Yangtze River Delta from the perspective of value-added trade and its promotion effect.

This article uses the Novy model improved by value-added trade data to measure the cost of inter-provincial trade in the Yangtze River Delta and, on this basis, uses the differential decomposition method to explore the promoting effect of inter-provincial trade costs on the development of inter-provincial trade in the Yangtze River Delta. The results show that the inter-provincial trade costs of the provinces/municipalities in the Yangtze River Delta have increased and decreased, but the changes are small, and there are significant differences in sectoral and bilateral trade costs; the results of the differential decomposition show that the contribution of inter-provincial trade costs to inter-provincial trade development in the Yangtze River Delta is much lower than that of economic growth. Therefore, the Yangtze River Delta should deepen the division of labor and cooperation, give full play to the radiation and leading role of Shanghai as an economic center, and accelerate the digital innovation transformation of the service industry to reduce inter-provincial trade costs and achieve a higher level of integrated development of the Yangtze River Delta.

Comparative study of total thoracoscopic mitral valve surgery and traditional open mitral valve surgery :propensity score matching study

Background: Conventional median open mitral valve replacement surgery usually requires a 20-30cm size incision to ensure adequate visual exposure. So, while we complete the valve replacement, it also brings about a series of problems. The appearance of TV thoracoscope changes the exposure of the surgical field. Because the microscopic field is enlarged, it not only makes the surgical vision clearer, but also greatly shortens the incision, reduces bleeding, and conceals the incision, minimizing the trauma and shortening the postoperative recovery time, which is in line with the concept of modern health. Aim: All technological innovation is controversial in the early stage, and it is such debate that can promote the progress and development of technology.This study was conducted in the context of this debate to summarize the experience of Total thoracoscopic mitral valve surgery in our center.Total thoracoscopic mitral valve replacement surgery and traditional median incision mitral valve replacement surgery were compared by the propensity score matching method.Evaluate its safety and merits. Methods: From January 2018 to December 2020, a total of 139 patients in the thoracoscopic group were eligible in the cardiothoracic surgery department of our hospital, and 1066 cases of traditional median sternotomy mitral valve replacement. After propensity score matching, 125 patients were selected in the thoracoscopic group, among 1066 patients with median incision MVR, 1:1 matched to 125, as the control group in the thoracoscopic group. Results: The results showed that the mean operative time in the thoracoscopic MVR group was significantly longer than that in the control group (185.73 ± 43.04 vs. 164.58 ± 40.28, p=0.0016). Similarly, both the mean CPB time and aortic block time were significantly longer than those in the control group (108.37±30.57min vs. 79.18±17.65min, p &lt;0.0001; 66.59±29.63min vs. 45.09±19.68min, p &lt;0.0001. Moreover, the proportion of patients with CPB greater than 120min and aortic block greater than 90min was significantly higher than the control group (24.1% vs. 3.2%, p &lt;0.0001,14.4% vs. 2.4%, p=0.0237). In addition, there was no significant difference in the mean ICU observation time between the two groups (49.35±34.51h vs. 48.72±25.89h, p=0. 8792). Differently, the mean endotracheal intubation time was significantly lower in the thoracoscopic MVR group compared to the control group (18.52±6.07h vs. 25.45±14.18h, p=0.0032). Similarly, the length of stay in the thoracoscopic group was 9.13 ± 4.58 days, which was significantly lower than 11.12 ± 5.76 days in the control group (p=0.0004). There was no significant difference in the postoperative hemoglobin concentration or platelet count between the two groups of MVR patients. Mean intraoperative bleeding volume in the thoracoscopic MVR group was significantly less than that in the control group (158.37±100.91ml vs.250.74 ± 81.34, P &lt;0.0001). Similarly, the mean postoperative discharge in the thoracoscopic MVR group was significantly than in the control group (428.39±361.38ml vs. 514.07 ± 347.92ml, p=0.0383). For patients with postoperative blood products, there were 37 (29.6%) in the thoracoscopic group and 33 (26.4%) in the control group. There was no significant difference between the two groups. Similarly, there was no significant difference in the mean total hospital costs between the two groups. Conclusion: This study shows that it has feasibility and safety for total thoracoscopic mitral valve replacement for mitral valve lesions, which can reduce the time and stay of the hospital compared with conventional direct surgery, and obtain good minimally invasive and cosmetic effect, and lay a theoretical and clinical foundation for the application of thoracoscopic technology in cardiac surgery, which has important scientific significance.

Estimating the economic impact of complications after open tibial fracture: A secondary analysis of the pilot Gentamicin Open Tibia trial (pGO-Tibia).

To estimate the indirect economic impact of tibial fractures and their associated adverse events (AEs) in Tanzania. A secondary analysis of the pilot Gentamicin Open (pGO)-Tibia randomized control trial estimating the indirect economic impact of suffering an AE, defined as a fracture-related infection (FRI) and/or nonunion, after an open tibial fracture in Tanzania. The pGO-Tibia trial was conducted from November 2019 to August 2021 at the Muhimbili Orthopaedic Institute in Dar es Salaam, Tanzania. One hundred adults with open tibial shaft fractures participated in this study. Work hours were compared between AE groups. Cost data were analyzed using a weighted-average hourly wage and converted into purchasing power parity-adjusted USD. Indirect economic impact was analyzed from the perspective of return to work (RTW), lost productivity, and other indirect economic and household costs. RTW was analyzed using a survival analysis. Half of patients returned to work at 1-year follow-up, with those experiencing an AE having a significantly lower rate of RTW. Lost productivity was nearly double for those experiencing an AE. There was a significant difference in the mean outside health care costs between groups. The total mean indirect cost was $2385 with an AE, representing 92% of mean annual income and an increase of $1195 compared with no AE. There were significantly more patients with an AE who endorsed difficulty affording household expenses postinjury and who borrowed money to pay for their medical expenses. This study identified serious economic burden after tibial fractures, with significant differences in total indirect cost between those with and without an AE. II.

Association of Osteoporosis-related Healthcare Costs with the Use of Tenofovir Disoproxil Fumarate and Tenofovir Alafenamide in Chronic Hepatitis B Patients: a Population-based National Cohort Study in Korea

Long-term administration of tenofovir disoproxil fumarate (TDF) for chronic hepatitis B (CHB) may lead to bone mineral density loss. Tenofovir alafenamide (TAF) developed to address these concerns. This study aimed to investigate whether there is a significant difference in osteoporosis-related healthcare costs between CHB patients treated with TDF and TAF. This study is a retrospective cohort study using claims data from the Health Insurance Review and Assessment Service (HIRA) covering the entire population in Korea. The cohort included CHB patients treated with TDF or TAF from November 2017 to April 2022. We applied inverse probability of treatment weighting (IPTW) to balance baseline characteristics observed for one-year preceding prescription date. Osteoporosis-related costs per patient per year (PPPY) included all healthcare costs with an osteoporosis diagnosis code including outpatient and hospitalization costs. 7,172 and 3,837 patients were administered TDF and TAF respectively. After IPTW, TDF group had higher outpatient costs ($11.2) compared to TAF group ($6.1), but the difference was not statistically significant (p=0.1001). The total hospitalization cost was $24.6 in TDF group and $9.8 in TAF group, not statistically significant (p=0.1633). This largescale population-based study found no significant difference in osteoporosis-related healthcare costs between CHB patients treated with TDF and TAF.

Techno-Economic Comparison of Low-Carbon Energy Carriers Based on Electricity for Air Mobility

The decarbonization of air mobility requires the decarbonization of its energy. While biofuels will play an important role, other low-carbon energy carriers based on electricity are considered, such as battery electrification and liquid hydrogen (LH2) or eFuel, a hydrogen-based energy carrier. Each energy carrier has its own conversion steps and losses and its own integration effects with aircraft. These combinations lead to different energy requirements and must be understood in order to compare their cost and CO2 emissions. Since they are all electricity-based, this study compares these energy carriers using the well-to-rotor methodology when applied to a standard vertical take-off and landing (VTOL) air mobility mission. This novel approach allows one to understand that the choice of energy carrier dictates the propulsive system architecture, leading to integration effects with aircraft, which can significantly change the energy required for the same mission, increasing it from 400 to 2665 kWh. These deviations led to significant differences in CO2 emissions and costs. Battery electrification is impacted by battery manufacturing but has the lowest electricity consumption. This is an optimum solution, but only until the battery weight can be lifted. In all scenarios, eFuel is more efficient than LH2. We conclude that using the most efficient molecule in an aircraft can compensate for the extra energy cost spent on the ground. Finally, we found that, for each of these energy carriers, it is the electricity carbon intensity and price which will dictate the cost and CO2 emissions of an air mobility mission.

Analysis of the effectiveness of combination antimicrobial therapy for Legionnaires' disease: A nationwide inpatient database study

ObjectivesThe effectiveness of monotherapy and combination therapy with quinolones and macrolides for treating Legionnaires’ disease remains uncertain; this study aimed to assess the comparative effectiveness of three treatment approaches. MethodsUsing a nationwide inpatient database, we analyzed 3560 eligible patients hospitalized for Legionnaires’ disease between April 1, 2014, and March 31, 2021; patients were divided into combination therapy, quinolone monotherapy, and macrolide monotherapy groups according to the antibiotics administered within 2 days of admission. We compared in-hospital mortality, total hospitalization costs, and length of stay across these groups using multiple propensity score analysis with inverse probability of treatment weighting. ResultsOf the 3560 patients, there were 564 (15.8%), 2221 (62.4%), and 775 (21.8%) patients in the combination therapy, quinolone monotherapy, and macrolide monotherapy groups, respectively. No significant differences were observed in in-hospital mortality between combination therapy and quinolone monotherapy groups, and between combination therapy and macrolide monotherapy groups. There were no significant differences in total hospitalization costs or length of stay among the three groups. ConclusionThe study suggests that there may not be a significant advantage in using a combination of quinolones and macrolides over monotherapy for the treatment of Legionnaires’ disease. Given the potential for increased side effects, careful consideration is advised when choosing this combination therapy.

Healthcare Resource Utilization and Costs in an At-Risk Population With Diabetic Retinopathy.

Several investigators have suggested the cost-effectiveness of earlier screening, management of risk factors, and early treatment for diabetic retinopathy (DR). We aimed to evaluate the extent of health care utilization and cost of delayed care by insurance type in a vulnerable patient population. A retrospective analysis of patients with DR was conducted using electronic medical record (EMR) data from January 2014 to December 2020 at Denver Health Medical Center, a safety net institution. Patients were classified by disease severity and insurance status. DR-specific costs were assessed via Current Procedural Terminology (CPT) codes over a 24-month follow-up period. Among the 313 patients, a higher proportion of non-English speaking patients were uninsured. Rates of proliferative DR at presentation differed across insurance groups (62% of uninsured, 42% of discount plan, and 33% of Medicare/Medicaid, P = 0.016). There was a significant difference in the total median cost between discount plan patients ($1258, interquartile range [IQR] = $0 - $5901) and both Medicare patients ($751, IQR = $0, $7148, P = 0.037) and Medicaid patients ($593, IQR = $0 - $6299, P = 0.025). There were higher rates of proliferative DR at presentation among the uninsured and discount plan patients and greater total median cost in discount plan patients compared to Medicare or Medicaid. These findings prioritize mitigating gaps in insurance coverage and barriers to preventative care among vulnerable populations. Advanced diabetic disease and increased downstream health care utilization and cost vary across insurance type, suggesting improved access to preventative care is needed in these specific at-risk populations.

Early versus late follicular phase ovarian stimulation: a randomized controlled trial

Research questionIs late follicular phase stimulation equally efficient as early follicular phase stimulation in a GnRH antagonist protocol in oocyte donors in terms of number of oocytes? DesignIn this open label, phase 3, non-inferiority, RCT using a two-arm design with 1:1 allocation ratio, 84 oocyte donors were allocated to early follicular start (control group, n=41), or late follicular start (study group, n=43). In the control group, patients followed a fixed GnRH antagonist protocol with r-FSH 225IU. In the study group, r-FSH 225IU was initiated in the late follicular phase. Primary outcome was number of oocytes. Secondary endpoints included number of mature oocytes, consumption of gonadotropins and GnRH antagonist, and stimulation cost. ResultsNumber of oocytes did not differ between control group and study group (intention-to-treat analysis 15.5±11.0 vs 14.0±10.7, p=0.52, per-protocol analysis 18.2±9.7 vs 18.8±7.8, p=0.62). Number of mature oocytes did not differ (14.1±8.1 vs 12.7±8.5, p=0.48). Duration of stimulation was shorter in the control group (10.0±1.6 vs 10.9±1.5 days, p=0.01). Total amount of r-FSH used was lower in the control group (2240.7±313.9 IU vs 2453.9±330.1 IU p=0.008). A GnRH antagonist was used for approximately 6 days in the control group, while in the study group, only in one patient a GnRH antagonist was prescribed (6.0±1.4 days vs 0.13±0.7 days p<0.001). There was a significant difference in medication cost per cycle (1147.9±182.8€ in control group, vs 979.9±129.0€ in study group, p<0.001). ConclusionsLate follicular phase stimulation is as efficient as early follicular phase stimulation in terms of number of oocytes.

Cognitive and neural mechanisms of voluntary versus forced language switching in Chinese-English bilinguals: an fMRI study.

The ecological validity of bilingual code-switching has garnered increasing attention in recent years. Contrary to traditional studies that have focused on forced language switching, emerging theories posit that voluntary switching may not incur such a cost. To test these claims and understand differences between forced and voluntary switching, the present study conducted a systematic comparison through both behavioral and neural perspectives. Utilizing fMRI alongside picture-naming tasks, our findings diverge from prior work. Voluntary language switching not only demonstrated switching costs at the behavioral level but also significantly activated brain regions associated with inhibitory control. Direct comparisons of voluntary and forced language switching revealed no significant behavioral differences in switching costs, and both shared several common brain regions that were activated. On the other hand, a nuanced difference between the two types of language switching was revealed by whole-brain analysis: voluntary switching engaged fewer language control regions than forced switching. These findings offer a comprehensive view of the neural and behavioral dynamics involved in bilingual language switching, challenging prior claims that voluntary switching imposes no behavioral or neural costs, and thus providing behavioral and neuroimaging evidence for the involvement of inhibitory control in voluntary language switching.

The impact of the site of myocardial infarction on in-hospital outcomes for patients with STEMI.

The territory and vessel involved in ST-elevation myocardial infarction (STEMI) is an important and there are limited contemporary studies from the national perspective. A retrospective cohort study was undertaken of national representative hospital admission in the National Inpatient Sample with a diagnosis of anterior or non-anterior STEMI between 2017 and 2020. Multiple logistic regression and multiple linear regressions were used to determine if there are any differences in in-hospital mortality, length of stay (LOS) and cost for anterior and non-anterior STEMI. A total of 655 915 admissions with STEMI were included in the analysis (267 920 anterior STEMI, and 387 995 non-anterior STEMI). Non-anterior STEMI was associated with a significant reduction in mortality (OR 0.91 95% CI 0.89-0.99, P = 0.011) and LOS (coefficient -0.15 95% CI -0.22 to -0.08, P < 0.001) compared to anterior STEMI but there was no significant difference in healthcare costs (-297 95% CI -688 to 74). Analyses considering the infarct-related artery showed that the worse outcomes were associated with left main lesions and left-sided lesions had worse outcomes than right coronary artery lesions. Non-anterior STEMI is associated with reduced mortality and LOS compared to anterior STEMI. Left-sided coronary lesions had worse outcomes, compared to right coronary lesions. STEMI should be considered in terms of the vessel or territory affected, in relation to outcomes and healthcare costs.

Treatment of Inflammatory Bowel Disease with Biologics in Japan: A Single-Center, Retrospective Pharmacoeconomic Study.

Biologics are essential for treating inflammatory bowel disease (IBD); however, only a few studies have validated cost-effective treatment options and patient factors for biologic use using real-world data from Japanese patients with IBD. Here, we aimed to provide pharmacoeconomic evidence to support clinical decisions for IBD treatment using biologics. We assessed 183 cases (127 patients) of IBD treated with biologics between November 2004 and September 2021. Data on patient background, treatment other than biologics, treatment-related medical costs, and effectiveness index (ratio of the C-reactive protein-negative period to drug survival time) were analyzed using univariate and multivariate logistic regression analyses. Drug survival was determined using Kaplan-Meier survival curve analysis. The outcomes were to validate a novel assessment index and elucidate the following aspects using this index: the effectiveness-cost relationship of long-term biologic use in IBD and cost-effectiveness-associated patient factors. Body mass index ≥25 kg/m2 and duration of hypoalbuminemia during drug survival correlated significantly with the therapeutic effectiveness of biologics. There were no significant differences in surgical, granulocyte apheresis, or adverse-event costs per drug survival time. Biologic costs were significantly higher in the group showing lower effectiveness than in the group showing higher effectiveness. These findings hold major pharmacoeconomic implications for not only improving therapeutic outcomes through the amelioration of low albumin levels and obesity but also potentially reducing healthcare expenditure related to the use of biotherapeutics. To our knowledge, this is the first pharmacoeconomic study based on real-world data from Japanese patients with IBD receiving long-term biologic therapy.

True Costs of Uterine Artery Embolization: Time-Driven Activity-Based Costing in Interventional Radiology Over a 3-Year Period

PurposeThe aim of this study is to uncover potential areas for cost savings in uterine artery embolization (UAE) using time-driven activity-based costing, the most accurate costing methodology for direct health care system costs. MethodsOne hundred twenty-three patients who underwent outpatient UAE for fibroids or adenomyosis between January 2020 and December 2022 were retrospectively reviewed. Utilization times were captured from electronic health record time stamps and staff interviews using validated techniques. Capacity cost rates were estimated using institutional data and manufacturer proxy prices. Costs were calculated using time-driven activity-based costing for personnel, equipment, and consumables. Differences in time utilization and costs between procedures by an interventional radiology attending physician only versus an interventional radiology attending physician and trainee were additionally performed. ResultsThe mean total cost of UAE was $4,267 ± $1,770, the greatest contributor being consumables (51%; $2,162 ± $811), followed by personnel (33%; $1,388 ± $340) and equipment (7%; $309 ± $96). Embolic agents accounted for the greatest proportion of consumable costs, accounting for 51% ($1,273 ± $789), followed by vascular devices (15%; $630 ± $143). The cost of embolic agents was highly variable, driven mainly by the number of vials (range 1-19) of tris-acryl gelatin particles used. Interventional radiology attending physician only cases had significantly lower personnel costs ($1,091 versus $1,425, P = .007) and equipment costs ($268 versus $317, P = .007) compared with interventional radiology attending physician and trainee cases, although there was no significant difference in mean overall costs ($3,640 versus $4,386; P = .061). ConclusionsConsumables accounted for the majority of total cost of UAE, driven by the cost of embolic agents and vascular devices.

ROBOtic Care Outcomes Project for acute gallbladder pathology.

Robotic cholecystectomy is being increasingly used for patients with acute gallbladder disease who present to the emergency department, but clinical evidence is limited. We aimed to compare the outcomes of emergent laparoscopic and robotic cholecystectomies in a large real-world database. Patients who received emergent laparoscopic or robotic cholecystectomies from 2020 to 2022 were identified from the Intuitive Custom Hospital Analytics database, based on deidentified extraction of electronic health record data from US hospitals. Conversion to open or subtotal cholecystectomy and complications were defined using ICD10 and/or CPT codes. Multivariate logistic regression with inverse probability treatment weighting (IPTW) was performed to compare clinical outcomes of laparoscopic versus robotic approach after balancing covariates. Cost analysis was performed with activity-based costing and adjustment for inflation. Of 26,786 laparoscopic and 3,151 robotic emergent cholecystectomy patients being included, 64% were female, 60% were ≥45 years, and 24% were obese. Approximately 5.5% patients presented with pancreatitis, and 4% each presenting with sepsis and biliary obstruction. After IPTW, distributions of all baseline covariates were balanced. Robotic cholecystectomy decreased odds of conversion to open (odds ratio, 0.68; 95% confidence interval, 0.49-0.93; p = 0.035), but increased odds of subtotal cholecystectomy (odds ratio, 1.64; 95% confidence interval, 1.03-2.60; p = 0.037). Surgical site infection, readmission, length of stay, hospital acquired conditions, bile duct injury or leak, and hospital mortality were similar in both groups. There was no significant difference in hospital cost. Robotic cholecystectomy has reduced odds of conversion to open and comparable complications, but increased odds of subtotal cholecystectomy compared with laparoscopic cholecystectomy for acute gallbladder diseases. Further work is required to assess the long-term implications of these differences. Therapeutic/Care Management; Level IV.

Trends in private caregiving cost after implementing a comprehensive nursing service covered by national health insurance: Interrupted time series

BackgroundThe Korean government has implemented a comprehensive nursing care service system (CNS) to mitigate the stress faced by caregivers. ObjectiveThis study aimed to assess trends in the estimated average costs of private caregiving and determine the difference in costs between those using CNS and those not using it. DesignA comparative interrupted time series analysis with a 2-year lag period verified total private caregiving cost trends; biannual differences in costs were evaluated based on using CNS. ParticipantsThe main unit of analysis was episode. We extracted a total of 6418 episodes of hospitalization in acute care settings that included the use of caregiving services (formal, informal caregiving and CNS). MethodsWe conducted segmented regression to assess the impact of CNS on total private caregiving costs using data from 2012 to 2018, excluding the years 2015 and 2016 of the Korean Health Panel dataset. ResultsWe presented that the immediate mean difference in total private caregiving costs between CNS users and non-users was −444.7 USD two years after the implementation of the CNS policy (95 % CI −714.5 to −174.5, p-value 0.001). Among individuals living in rural areas, two years after the implementation of the CNS policy, there was a significant immediate mean cost difference of −476.9 USD in total private caregiving costs between CNS users and non-users (p-value 0.011). Similarly, for episodes with a Charlson Comorbidity Index (CCI) score of 0 to 1, there was a substantial immediate mean cost difference in total private caregiving costs between CNS users and non-users, amounting to −399.9 USD two years after the CNS policy (p-value 0.008). ConclusionsThis study evaluated the trend of total private caregiving costs between groups using and not using CNS. After two years of being covered by CNS health insurance, those who utilized CNS paid $433 less for their total private caregiving cost over a 6-month period, compared to those who did not use CNS. The adoption of CNS may be an effective system for relieving the financial burden on inpatients in need of private caregiving services.
