Patient-Centered Cost Saving and Positive Environmental Impact With the Introduction of Telehealth Services at a Single Center.

OBJECTIVES: To establish the patient-specific cost and time savings associated with telemedicine with the secondary environmental benefits of virtual visits within a tertiary referral center sub-specialty urology clinic. METHODS: An electronic health record query was made of all urology telehealth visits that have occurred between October 4, 2020 and October 10, 2020 at a single academic center. We evaluated the cost of travel for an in-person visit based on zip code data. To adjust for productivity loss, the cost of missed work was added as either full day or half day-based distance and average compensation per day based on zip code data. Environmental impact was calculated using average CO2 emissions per mile not traveled. RESULTS: There were 6444 patients seen in the urology clinic via telehealth during the 6-month period. Urology patients traveled on average 69 ± 148 miles round-trip for an appointment. The average cost savings per patient including the cost of the gas and time away from work was $152.78 ± $105.90. Overall, over a 6-month period, the total cost savings was $984,534.73 for the 6444 patients seen via telemedicine. There was also a significant environmental impact of the decreased travel burden with 153.36 metric tons of CO2 emissions eliminated. CONCLUSIONS: With the implementation of telehealth during the COVID-19 pandemic, patients have been able to save a substantial amount of time and money primarily driven by the decreasing work hours lost and cost of travel.

Savings Through Telemedicine: Initial Data From a Hospital-at-Home Program.

OBJECTIVE: We aimed to estimate travel-related time and cost savings from the use of telemedicine for an inpatient hospital-at-home program. METHODS: This was a retrospective study on the initial data obtained from a newly implemented hospital-at-home program from June 26, 2023, to March 31, 2024. Time cost savings were calculated based on difference between time spent on teleconsultation versus time needed to travel a round trip to patients' homes to conduct physical consultation via home visit. Travel distances were calculated based on the distance of patient's homes from the hospital. RESULTS: There were 505 teleconsultations (497 scheduled, 8 unscheduled) delivered throughout 132 enrollments. Total travel distance saved was 4022 km. Total time savings was 18 707 minutes or 13.0 days. Total trip cost savings were Singapore dollars 4618.70. CONCLUSIONS: Despite being a newly introduced program, utilization of telemedicine in delivery of hospital-at-home showed time savings for the clinicians, cost savings from the distance needed to travel otherwise. Incorporation of telemedicine in hospital-at-home delivery demonstrated time and distance savings even at the pilot phase of program.

A review of biosimilars in psoriasis: impacts on efficacy, safety, access, and a first-hand look at biosimilar cost savings within the department of veterans affairs.

BACKGROUND: Psoriasis is a chronic immune-mediated systemic disease whose treatment has been revolutionized due to the induction of monoclonal antibody-based biologics. However, access to these drugs has been limited due to their high cost. Biosimilars utilize reverse engineering to create a highly similar product to an originator drug following patent expiration and provide an avenue to reduce costs of biologic treatment. This review seeks to synthesize current knowledge about the development, efficacy, and established benefits of biosimilars, including cost savings and increased access to biologic medicines. RESULTS: In 2023, the Veterans Health Administration (VA) generated a cost avoidance of over 67 million dollars through use of 6 currently adopted biosimilars across all indications. There is an opportunity for further cost avoidance, with the pre-set percent discount of statutory contract prices necessary for the adoption of future biosimilars, including adalimumab and etanercept, set at over 50%. CONCLUSIONS: Biosimilars appear to offer an overall effective, safe, and well-tolerated treatment method for patients with psoriasis and are already providing substantial cost savings within the VA. Additional education is needed to address sources of ambivalence for both patients and providers to assist in further uptake of biosimilars for the treatment of psoriasis.

Institutional Conversion to Energy-Efficient Ultra-Low Freezers Decreases Carbon Footprint and Reduces Energy Costs.

Introduction: The storage of biospecimens is a substantial source of greenhouse gas emissions and institutional energy costs. Energy-intensive ultra-low temperature (ULT) freezers used for biospecimen storage are a significant source of carbon emissions. ENERGY STAR-certified ULT freezers have the potential to decrease the carbon footprint. Objective: Quantify the impact of an institutional-scale freezer conversion program on carbon emissions and energy costs. Methods: A ULT freezer energy use prediction model was developed to identify and replace the most inefficient freezers in the research building for this pilot, and eventually institution-wide. Multiple linear regression factors included the number of years of use, storage volume, and ENERGY STAR certification status. Electrical usage and carbon emissions were quantified before and after replacement with ENERGY STAR models. Logistical methods were developed to decrease the risks of exposure of frozen samples to ambient temperature during content transfers. Institution-wide energy costs were derived by converting electrical burden to electrical costs. Carbon footprint assessment from ULT freezer operation was computed using the U.S. EPA Greenhouse Gas Equivalencies Calculator. Results: The pilot project revealed an annual reduction of 310,493 kilowatt hours of electrical usage, equivalent to 134 metric tons of carbon emissions. Annual electrical costs were reduced by $55,889 resulting in an 8-year payback on the initial investment. Using the pilot results, we modeled the benefit of the freezer exchange across the entire institution. The modeling predicted that conversion of the institution's remaining 1119 conventional ULT freezers to ENERGY STAR models would lower annual electrical usage by 7,911,549 kilowatt hours (3423 metric tons of carbon emissions), resulting in savings of over $1.4 million annually. Conclusion: Our methods make a large-scale initiative to replace energy-inefficient ULT freezers logistically possible, reduce carbon footprint, and demonstrate an attractive return on investment while proactively protecting valuable research materials.

Estimation of the maximum potential cost saving from reducing serious adverse events in hospitalized patients.

PURPOSE: The increasing use of advanced medical technologies to detect adverse events, for instance, artificial intelligence-assisted technologies, has shown promise in improving various aspects within health care but may also come with substantial expenses. Therefore, understanding the potential economic benefits can guide decision-making processes regarding implementation. We aimed to estimate the potential cost savings associated with reducing length of stay and avoiding readmissions within the framework of an artificial intelligence-assisted vital signs monitoring system. METHODS: We used data from Danish national registries and coarsened exact matching to estimate the difference in length of stay and probability of readmission among adult in-hospital patients exposed to and not exposed to serious adverse events. We used these estimates to calculate the maximum potential savings that could be achieved by early detection of adverse events to reduce length of stay and avoid readmissions. RESULTS: Patients exposed to serious adverse events during admission had 2.4 (95% CI: 2.4-2.5) additional hospital bed days and had 14% (95% CI 11%-17%) higher odds of readmissions compared with patients not exposed to such events. A base case scenario yielded maximum potential savings if one patient avoided a serious adverse event of EUR 2040 due to reduced length of stay and EUR 43 due to avoidance of readmissions caused by serious adverse events. CONCLUSION: Reductions in serious adverse events are associated with decreased healthcare costs due to reduced length of stay and avoided readmissions. Artificial intelligence-assisted vital signs monitoring systems are one potential approach to reduce serious adverse events, however, the ability of this technology to reduce adverse events remains unclear. Comprehensive prospective analyses of such systems including the intervention and implementation costs are necessary to understand their full economic impact.

Economic Impact of Ambulatory Blood Pressure Monitoring Compared With Clinical Blood Pressure Monitoring: A Simulation Model.

Background: Ambulatory blood pressure monitoring (ABPM) is considered the gold standard for proper diagnosis of hypertension. Yet, access to ABPM in the U.S. is limited, and the extent of coverage by commercial health plans remains uncertain, potentially limiting access to ABPM among commercially insured patients. Objective: This study aims to assess the net cost impact of using ABPM in comparison to clinical blood pressure monitoring (CBPM) in the U.S. over a 5-year time period. Design methods: Using a Markov Model, we estimate the 5-year cumulative cost impact of using ABPM to confirm a prior diagnosis of primary hypertension using CBPM to avoid treatment for white-coat hypertension (WCH) in a hypothetical cohort of 1000 patients from a U.S. healthcare system perspective. The probability and cost inputs for the model were derived from available literature. Base-case model parameters were varied to account for different scenarios. Results: Base-case results indicate using ABPM instead of CBPM over 5 years saves a total of $348,028, reflecting an average per-person-per-year (PPPY) cost saving of $70. In sensitivity analyses, almost all cases reveal ABPM as a cost-saving approach compared to CBPM, with cost savings reaching up to $228 PPPY in the highest hypertension treatment cost model. Regression results reveal that ABPM was cost-saving compared to CBPM if ABPM annual payment rates are $100 or less and annual hypertension treatment costs are ⩾$300. Conclusion: The potential cost-savings of using ABPM instead of CBPM found in our simulation model underscores the need for confirmatory research using real-world data to support increased use of ABPM as the standard diagnostic approach for hypertension.

National cost savings, operational and safety benefits from use of magnetocardiography in the assessment of emergency department chest pain patients.

Study objectives: Patients frequently present to the emergency department (ED) with chest pain requiring further risk stratification. Traditional cardiac diagnostics such as stress testing may expose patients to ionizing radiation, may not be readily available, may take significant time for testing and interpretation, and adds cost to the workup. Magnetocardiography (MCG) is an alternative approach to assess candidates more quickly and efficiently than routine downstream testing. Design: We created and ran 1000 trials of a Monte Carlo simulation. Using this simulation, we modeled the national annual impact by averting further cardiac diagnostics. Setting: All EDs in the United States. Participants: All ED adult patients with chest pain. Interventions: Simulated use of MCG to reduce avoidable downstream cardiac diagnostics. Main outcome measures: Our primary outcome was to estimate the impact of an MCG-first strategy on the annual national cost savings among eligible patients in the ED. Our secondary outcomes were the estimated reduction in short-stay hospitalizations, cancer cases, and cancer deaths due to radiation exposure. Results: An MCG-first strategy was estimated to save a mean (±SD) of $574 million (±$175 million) by avoiding 555,000 (±93,000) downstream cardiac diagnostic tests. This resulted in a national annual cumulative decrease of 500,000 (±84,000) hospitalizations, 7,600,000 (±1,500,000) bed hours, 409 (±110) new cancer diagnoses, and 210 (±56) new cancer deaths due to radiation exposure from avoidable cardiac diagnostics. Conclusions: If adopted widely and used consistently, an MCG-first strategy among eligible patients could yield substantial benefits by averting avoidable cardiac diagnostic testing.

Assessing the Impact of a Designated Pharmacist Intervention on Drug Treatment Costs and Technical Efficiency in the Hemato-Oncology Outpatient Clinic.

OBJECTIVES: This study aimed to investigate the impact of a designated pharmacist (DPha) intervention in a hemato-oncology unit, focusing on reducing drug treatment costs and improving technical efficiency (TE). METHODS: Data from an 8-month intervention in the Israeli Clalit Health Services hemato-oncology outpatient unit were analyzed. During the study, the DPha reviewed the drug therapies being administered. After the review, a recommendation letter was sent, if relevant, to the treating physician. Data on drug treatment costs and interventions were meticulously collected and analyzed from the perspective of the insurer. A simple design was used to assess the DPha intervention's contribution to TE and cost reduction, which was used to generate credible and transparent estimates. Sensitivity analyses were conducted to assess the robustness of 2 major variables: drug prices and pharmacist salaries. RESULTS: Over 8 months, DPha interventions led to a $279 191 cost reduction for 91 patients, resulting in net savings of $269 420 ($2960 per patient). Noteworthy is the $411 savings for each hour worked by the pharmacist, with a major impact on medications not insurer approved for the patient's condition ($101 151) and discontinuing inappropriate medications ($52 681). Biological drug optimization accounted for 81% of total savings. Sensitivity analyses demonstrated significant cost savings across various drug prices and pharmacist salary scenarios. CONCLUSIONS: The study proposes a practical framework for optimizing pharmacist services and reducing the inappropriate use of costly oncology medications. Incorporating a DPha enhances TE and yields significant cost reductions, offering valuable insights for insurers, policy makers, and healthcare professionals.

Cost-consequence analysis of computer vision-based skin prick tests: implications for cost containment in Switzerland.

BACKGROUND: Skin prick tests (SPTs), or intraepidermal tests, are often the first diagnostic approach for people with a suspected allergy. Together with the clinical history, SPTs allow doctors to draw conclusions on allergies based on the sensitization pattern. The purpose of this study is to investigate the potential cost consequences that would accrue to a Swiss University hospital after the adoption of computer vision-based SPTs. METHODS: We conducted a cost-consequence analysis from a hospital's perspective to evaluate the potential cost consequences of using a computer vision-based system to read SPT results. The patient population consisted of individuals who were referred to the allergology department of one of the five university hospitals in Switzerland, Inselspital, whose allergology department averages 100 SPTs a week. We developed an early cost-consequence model comparing two SPT techniques; computer vision-based SPTs conducted with the aid of Nexkin DSPT and standard fully manual SPTs. Probabilistic sensitivity analysis and additional univariate sensitivity analyses were used to account for uncertainty. RESULTS: The difference in average cost between the two alternatives from a hospital's perspective was estimated to be CHF 7 per SPT, in favour of the computer vison-based SPTs. Monte Carlo probabilistic simulation also indicated that SPTs conducted using the computer vision-based system were cost saving compared to standard fully manual SPTs. Sensitivity analyses additionally demonstrated the robustness of the base case result subject to plausible changes in all the input parameters, with parameters representing the costs associated with both SPT techniques having the largest influence on the incremental cost. However, higher sensitization prevalence rates seemed to favour the more accurate standard fully manual SPTs. CONCLUSION: Against the backdrop of rising healthcare costs especially in Switzerland, using computer-aided or (semi) automated diagnostic systems could play an important role in healthcare cost containment efforts. However, results should be taken with caution because of the uncertainty associated with the early nature of our analysis and the specific Swiss context adopted in this study.

The anterior-based muscle-sparing approach is cost-effective when compared with posterolateral and direct anterior approaches for total hip arthroplasty.

PURPOSE: Research relating to Total Hip Arthroplasty (THA) has found the anterior-based muscle-sparing (ABMS) approach improves both intraoperative and postoperative outcomes when compared to other THA approaches. This study compares the costs and outcomes of the ABMS approach and standard of care (SOC) to determine the relative cost-effectiveness. METHODS: A decision-analytic model was utilized to estimate intraoperative outcomes (i.e. length of procedure, length of stay (LOS), and transfusion rates) and 90-day postoperative complications (deep infection, periprosthetic fracture, and dislocation). Data relating to postoperative complications, intraoperative outcomes, and costs (adjusted to 2023 USD) were obtained from the literature. Model results were presented as incremental costs and complications avoided using a willingness-to-pay threshold of $100,000. We conducted both one-way sensitivity analysis (OWSA), varying each parameter individually within a specific range, and probabilistic sensitivity analysis (PSA) where parameters were varied simultaneously. In scenario analysis, ABMS was also compared to the posterior approach (PA) and direct anterior approach (DAA) individually. RESULTS: ABMS THA was found to have superior results compared to SOC THA over a 90-day time horizon since it decreased major complications by 0.00186 per patient and cost by $3,851 per patient. The PSA found the ABMS approach dominates SOC and is cost-effective in approximately 98.29% and 100% of 10,000 iterations, respectively. Comparing ABMS with only PA procedures increased cost savings per patient to $4,766 while it decreased to $3,242 when comparing ABMS to only DAA procedures. Length of procedure, LOS, and discharge disposition were the main cost drivers. CONCLUSIONS: This analysis demonstrates the ABMS approach for THA is a cost-effective technique when compared to PA and DAA, which may provide an opportunity for cost savings to the healthcare system.

Financial Benefits of Renal Dose-Adjusted Dipeptidyl Peptidase-4 Inhibitors for Patients with Type 2 Diabetes and Chronic Kidney Disease.

BACKGRUOUND: Dipeptidyl peptidase-4 (DPP4) inhibitors are frequently prescribed for patients with type 2 diabetes; however, their cost can pose a significant barrier for those with impaired kidney function. This study aimed to estimate the economic benefits of substituting non-renal dose-adjusted (NRDA) DPP4 inhibitors with renal dose-adjusted (RDA) DPP4 inhibitors in patients with both impaired kidney function and type 2 diabetes. METHODS: This retrospective cohort study was conducted from January 1, 2012 to December 31, 2018, using data obtained from common data models of five medical centers in Korea. Model 1 applied the prescription pattern of participants with preserved kidney function to those with impaired kidney function. In contrast, model 2 replaced all NRDA DPP4 inhibitors with RDA DPP4 inhibitors, adjusting the doses of RDA DPP4 inhibitors based on individual kidney function. The primary outcome was the cost difference between the two models. RESULTS: In total, 67,964,996 prescription records were analyzed. NRDA DPP4 inhibitors were more frequently prescribed to patients with impaired kidney function than in those with preserved kidney function (25.7%, 51.3%, 64.3%, and 71.6% in patients with estimated glomerular filtration rates [eGFRs] of ≥60, <60, <45, and <30 mL/min/1.73 m2, respectively). When model 1 was applied, the cost savings per year were 7.6% for eGFR <60 mL/min/1.73 m2 and 30.4% for eGFR <30 mL/min/1.73 m2. According to model 2, 15.4% to 51.2% per year could be saved depending on kidney impairment severity. CONCLUSION: Adjusting the doses of RDA DPP4 inhibitors based on individual kidney function could alleviate the economic burden associated with medical expenses.

A health economic pilot study comparing two diabetic retinopathy screening strategies.

To compare two screening strategies for diabetic retinopathy (DR), and to determine the health-economic impact of including optical coherence tomography (OCT) in a regular DR screening. This cross-sectional study included a cohort of patients (≥ 18 years) with type 1 or 2 diabetes mellitus (T1D or T2D) from a pilot DR screening program at Oslo University Hospital, Norway. A combined screening strategy where OCT was performed in addition to fundus photography for all patients, was conducted on this cohort and compared to our existing sequential screening strategy. In the sequential screening strategy, OCT was performed on a separate day only if fundus photography indicated diabetic macular edema (DME). The presence of diabetic maculopathy on fundus photography and DME on OCT was determined by two medical retina specialists. Based on the prevalence rate of diabetic maculopathy and DME from the pilot, we determined the health-economic impact of the two screening strategies. The study included 180 eyes of 90 patients. Twenty-seven eyes of 18 patients had diabetic maculopathy, and of these, 7 eyes of 6 patients revealed DME on OCT. When diabetic maculopathy was absent on fundus photographs, OCT could not reveal DME. Accordingly, 18 patients (20%) with diabetic maculopathy would have needed an additional examination with OCT in the sequential screening strategy, 6 (33%) of whom would have had DME on OCT. In an extended healthcare perspective analysis, the cost of the sequential screening strategy was higher than the cost of the combined screening strategy. There was a weak association between diabetic maculopathy on fundus photography and DME on OCT. The health economic analysis suggests that including OCT as a standard test in DR screening could potentially be cost-saving.

Modelling the opportunity for cost-savings or patient access with biosimilar adalimumab and tocilizumab: a European perspective.

OBJECTIVES: Biosimilars improve patient access by providing cost-effective treatment options. This study assessed the potential for savings and expanded patient access with increased use of two biosimilar disease modifying anti-rheumatic drugs (DMARDs): (a) approved adalimumab biosimilars and (b) the first tocilizumab biosimilar, representing an established biosimilar field and a recent biosimilar entrant in France, Germany, Italy, Spain, and the United Kingdom (UK). METHODS: Separate ex-ante analyses were conducted for each country, parameterized using country-specific list prices, unit volumes annually, and market shares for each therapy. Discounting scenarios of 10%, 20%, and 30% were tested for tocilizumab. Outputs included direct cost-savings associated with drug acquisition or the incremental number of patients that could be treated if savings were redirected. Two biosimilar conversion scenarios were tested. RESULTS: Savings associated with a 100% conversion to adalimumab biosimilar ranged from €10.5 to €187 million (UK and Germany, respectively), or an additional 1,096 to 19,454 patients that could be treated using the cost-savings. Introduction of a tocilizumab biosimilar provided savings up to €29.3 million in the most conservative scenario. Exclusive use of tocilizumab biosimilars (at a 30% discount) could increase savings to €28.8 to €113 million or expand access to an additional 43% of existing tocilizumab users across countries. CONCLUSION: This study demonstrates the benefits that can be realized through increased biosimilar adoption, not only in an untapped tocilizumab market, but also through incremental increases in well-established markets such as adalimumab. As healthcare budgets continue to face downwards pressure globally, strategies to increase biosimilar market share could prove useful to help manage financial constraints.

Savings from the introduction of BPaL and BPaLM regimens at the country level.

BACKGROUND: In 2022, the WHO recommended the 6-month regimens BPaL (bedaquiline + pretomanid + linezolid) and BPaLM (BPaL + moxifloxacin) as treatment options for most forms of drug-resistant TB. SLASH-TB estimates the cost-saving and cost-effectiveness for the healthcare system and patients when a country switches from current standard-of-care treatment regimens to BPaL/BPaLM. METHODOLOGY: Country data from national TB programmes (NTP) are used to calculate the costs for all regimens and treatment outcomes. Where BPaL/BPaLM is not currently used, clinical trial outcomes data are used to estimate cost-effectiveness. DALYs are calculated using the Global Burden of Disease (GBD) database. RESULTS: We present the results of four countries that have used the tool and shared their data. When shorter and longer regimens are replaced with BPaL/BPaLM, the savings per patient treated in Pakistan, the Philippines, South Africa, and Ukraine are $746, $478, $757, and $2,636, respectively. An increased number of patients would be successfully treated with BPaL/BPaLM regimens, with 411, 1,025, 1,371 and 829 lives saved and 20,179, 27,443, 33,384 and 21,924 DALYs averted annually in the four countries, respectively. CONCLUSION: Through BPaL/BPaLM regimens, drug-resistant TB treatment has become more effective, shorter, less burdensome for patients, cheaper for both health systems and patients, and saves more lives.

CONTEXTE: En 2022, l'OMS a préconisé l'utilisation des schémas thérapeutiques (bedaquiline + pretomanid + linezolid) et BPaLM (BPaL + moxifloxacin), d'une durée de 6 mois, comme alternatives pour traiter la plupart des formes de TB résistante aux médicaments. SLASH-TB a réalisé une estimation des économies et de la rentabilité pour le système de santé et les patients lorsqu'un pays décide de passer des schémas thérapeutiques standards actuels au BPaL/BPaLM. MÉTHODOLOGIE: Les programmes nationaux de lutte contre la TB (NTP) utilisent les données nationales pour évaluer les coûts des différents schémas thérapeutiques et des résultats des traitements. Si le BPaL/BPaLM n'est pas utilisé actuellement, les données des essais cliniques sont utilisées pour estimer le rapport coût-efficacité. Les années de vie ajustées sur l'incapacité (DALYs, pour l'anglais « disability-adjusted life-years ¼) sont calculées à l'aide de la base de données Global Burden of Disease (GBD). RÉSULTATS: Nous présentons les résultats de quatre pays qui ont utilisé l'outil et partagé leurs données. Lorsque les schémas plus courts et plus longs sont remplacés par BPaL/BPaLM, les économies par patient traité au Pakistan, aux Philippines, en Afrique du Sud et en Ukraine sont respectivement de 746, 478, 757 et 2 636 dollars. L'utilisation des schémas BPaL/BPaLM permettrait de traiter un plus grand nombre de patients avec succès, ce qui sauverait respectivement 411, 1 025, 1 371 et 829 vies et éviterait 20 179, 27 443, 33 384 et 21 924 DALYs par an dans les quatre pays. CONCLUSION: Les schémas BPaL/BPaLM ont révolutionné le traitement de la tuberculose pharmacorésistante en le rendant plus efficace, plus rapide, moins contraignant pour les patients, plus économique pour les systèmes de santé et les patients, et en sauvant un plus grand nombre de vies.

Controlled CMS Data Demonstrates a Cost and Clinical Advantage for Hyperbaric Oxygen for Radiation Cystitis.

Introduction: Increasing cancer survivorship, in part due to new radiation treatments, has created a larger population at risk for delayed complications of treatment. Radiation cystitis continues to occur despite targeted radiation techniques. Materials and Methods: To investigate value-based care applying hyperbaric oxygen (HBO2) to treat delayed radiation cystitis, we reviewed public-access Medicare data from 3,309 patients from Oct 1, 2014, through Dec 31, 2019. Using novel statistical modeling, we compared cost and clinical effectiveness in a hyperbaric oxygen group to a control group receiving conventional therapies. Results: Treatment in the hyperbaric group provided a 36% reduction in urinary bleeding, a 78% reduced frequency of blood transfusion for hematuria, a 31% reduction in endoscopic procedures, and fewer hospitalizations when study patients were compared to control. There was a 53% reduction in mortality and reduced unadjusted Medicare costs of $5,059 per patient within the first year after completion of HBO2 treatment per patient. When at least 40 treatments were provided, cost savings per patient increased to $11,548 for the HBO2 study group compared to the control group. This represents a 37% reduction in Medicare spending for the HBO2-treated group. We also validate a dose-response curve effect with a complete course of 40 or more HBO2 treatments having better clinical outcomes than those treated with fewer treatments. Conclusion: These data support previous studies that demonstrate clinical benefits now with cost- effectiveness when adjunctive HBO2 treatments are added to routine interventions. The methodology provides a comparative group selected without bias. It also provides validation of statistical modeling techniques that may be valuable in future analysis, complementary to more traditional methods.

Drug utilization reviews to reduce inappropriate drug use and pharmaceutical costs in inpatients based on diagnosis-related group data.

BACKGROUND: Irrational pharmacotherapy and increasing pharmacy costs remain major concerns in healthcare systems. Pharmacists are expected to employ diagnosis-related group (DRG) data to analyse inpatient pharmacy utilization. OBJECTIVE: This project aimed to pilot an efficient pharmacist-led programme to analyse factors related to pharmacy expenses, evaluate the rational use of drugs in batch processing, and make further interventions based on DRG data. METHODS: Patients from the OB25 (caesarean section without comorbidities or complications) DRG were selected in 2018, and the most relevant factors were identified through statistical analysis. Interventions were implemented by sending monthly reports on prescribing data and drug review results for the same DRGs to the department starting in 2019. Pre-post comparisons were conducted to demonstrate changes in pharmacy costs and appropriateness at a tertiary teaching hospital with 2,300 beds in China. RESULTS: A total of 1,110 patients were identified from the OB25 DRG data in 2018. Multivariate linear analysis indicated that the number of items prescribed and wards substantially influenced pharmacy expenditure. Drugs labelled as vital, essential, and non-essential revealed that 46.6% of total pharmacy costs were spent on non-essential drugs, whereas 38.7% were spent on vital drugs. The use of inappropriate pharmaceuticals and drug items was substantially reduced, and the average pharmacy cost after intervention was 336.7 RMB in 2020. The benefit-cost ratio of the programme was 9.86. CONCLUSION: Interventions based on DRG data are highly efficient and feasible for reducing inpatient pharmacy costs and non-essential drug use.

Assessment of the utilization of real-time prescription benefits for patient cost savings within an outpatient setting.

Background: This study evaluates the impact of Real-Time Prescription Benefits (RTPB), a tool integrated into electronic health records (EHRs), on patient out-of-pocket costs in an academic institution. RTPB provides prescribers with alternative, less expensive medications based on insurance plans. The primary measure was cost-savings, defined as the difference between the out-of-pocket cost of the prescribed medication and its alternative. Methods: A retrospective analysis of prescriptions from outpatient clinics in a university-based health system was conducted between May 2020 and July 2021. Prescriptions were analyzed at the 2nd level of the Anatomical Therapeutic Chemical (ATC) classification system. Costs were standardized to a 30-day supply. Standardized cost and total cost per prescription, and overall savings for the top 20 medication classes at the 2nd ATC level were calculated. The overall impact of RTPB was estimated based on selecting the least expensive alternative suggested by RTPB. Results: The study found that RTPB information was provided for 22% of prescriptions, with suggested alternatives for 1.26%. Among prescriptions with an alternative selected, the standardized average cost saving was $38.83. The study realized $15,416 in patient total cost savings. If the least expensive RTPB-suggested alternative were chosen for all prescriptions, an estimated $276,386 could have been saved. Psychoanaleptic and psycholeptic medications were the most prescribed with an alternative, with most savings in specialty drugs like anthelmintic and immunostimulant medications. Conclusion: The study highlights the importance of RTPB in reducing patient costs. It reports patient cost-savings with RTPB in prescribing decisions. Future research could explore the impact of RTPB on medication adherence using pharmacy claims data.

Impact of reducing iodinated intravenous contrast volume in brain CT on image diagnostic quality.

PURPOSE: To investigate whether reducing the volume of intravenous iodinated contrast material injected during brain computed tomography (CT) provides reliable and accurate imaging without compromising diagnostic accuracy. METHODS: This prospective study enrolled patients undergoing enhanced brain CT at a single tertiary hospital. Subjects who agreed to participate received a reduced dose of 60 ml contrast. The images were compared to an age and gender-matched control group who received the conventional 80 cc dose. Neuroradiologists assessed image quality and interpretation using a 5-point Likert scale with six specific domains. Based on ICC, inter-rater reliability was high at 0.873. Multiple linear regression predicted overall diagnostic accuracy based on contrast dose, age, and gender. Visual Grading Characteristics (VGC) analysis was also performed to quantify regional brain enhancement differences between the two contrast groups. RESULTS: The study included 47 patients in the 60 cc group and 55 in the 80 cc control group. The results showed the 80 cc group had significantly higher enhancement ratings compared to 60 cc for all six structures assessed. The differences between groups ranged from -0.241 to -0.433 (p < 0.001) on the 5-point scale.The VGC analysis confirmed significantly greater brain parenchymal enhancement in the 80 cc group compared to the 60 cc group. CONCLUSION: The findings indicate that reducing the intravenous iodinated contrast material volume during brain CT from 80 cc to 60 cc leads to a statistically significant reduction in image quality and diagnostic accuracy. Further research with larger cohorts is needed to confirm these findings and assess the clinical impact of these differences.

Potential Cost Savings with 60-day Peripheral Nerve Stimulation Treatment in Chronic Axial Low Back Pain.

INTRODUCTION: Chronic axial low back pain (CLBP) that is not responsive to medication management or physical therapy often requires significant clinical intervention. Several interventional pain management options exist, including a 60-day peripheral nerve stimulation (PNS) treatment. This economic evaluation investigated the potential for projected cost savings associated with prioritizing 60-day PNS treatment relative to a 'standard of care' (SOC) approach (where patients do not have access to 60-day PNS). METHODS: A decision tree (supervised machine learning) model tracked treatment progression across two hypothetical cohorts of US patients with CLBP in whom non-interventional options were ineffective (Cohort A: treatment starting with 60-day PNS followed by any additional interventional and surgical treatments versus Cohort B: standard of care interventional and surgical treatments without access to 60-day PNS). Treatment efficacy estimates were based on published success rates. Conditional on treatment failure, up to two additional interventions were considered within the 12-month time frame in both cohorts. SOC treatment options included epidural injection, radiofrequency ablation (RFA), basivertebral nerve ablation (BVNA), PNS permanent implant (PNS-PI), spinal cord stimulator (SCS) trial/implant, and spinal fusion surgery. Treatment choice probabilities in both cohort algorithms were based on clinician interviews. Costs were based on national Medicare reimbursement levels in the ambulatory surgery center (ASC) setting. Savings reflected the difference in projected costs between cohorts. A Monte Carlo simulation and sensitivity analyses were conducted to generate confidence intervals and identify important inputs. RESULTS: The treatment algorithm which prioritized initial 60-day PNS treatment was projected to save $8056 (95% CI $6112-$9981) per patient during the first year of interventional treatment relative to the SOC approach. CONCLUSIONS: Use of the 60-day PNS treatment as an initial interventional treatment in patients with CLBP may result in significant savings for Medicare. Projected savings may be even larger for commercial payers covering non-Medicare patients.

Evaluation of a Semi-Automated Wound-Halving Algorithm for Split-Wound Design Studies: A Step towards Enhanced Wound-Healing Assessment.

Background: Chronic leg ulcers present a global challenge in healthcare, necessitating precise wound measurement for effective treatment evaluation. This study is the first to validate the "split-wound design" approach for wound studies using objective measures. We further improved this relatively new approach and combined it with a semi-automated wound measurement algorithm. Method: The algorithm is capable of plotting an objective halving line that is calculated by splitting the bounding box of the wound surface along the longest side. To evaluate this algorithm, we compared the accuracy of the subjective wound halving of manual operators of different backgrounds with the algorithm-generated halving line and the ground truth, in two separate rounds. Results: The median absolute deviation (MAD) from the ground truth of the manual wound halving was 2% and 3% in the first and second round, respectively. On the other hand, the algorithm-generated halving line showed a significantly lower deviation from the ground truth (MAD = 0.3%, p < 0.001). Conclusions: The data suggest that this wound-halving algorithm is suitable and reliable for conducting wound studies. This innovative combination of a semi-automated algorithm paired with a unique study design offers several advantages, including reduced patient recruitment needs, accelerated study planning, and cost savings, thereby expediting evidence generation in the field of wound care. Our findings highlight a promising path forward for improving wound research and clinical practice.
