Cost-per-Response Analysis of Pure Hypochlorous Acid Among Patients with Chronic Venous Leg Ulcers: A Health Economic Analysis.

OBJECTIVE: To estimate the total cost-per-wound healing response (CPR) and the per-day CPR of patients with chronic leg ulcers treated with pure hypochlorous acid (pHA) as part of their overall would healing regimen. METHODS: The authors developed a deterministic decision-tree model to estimate the incremental CPR for pHA. The analysis was performed using clinical data from a published single-arm prospective study. The outcome of interest was re-epithelialization at 90 days. Economic data for pHA were based on public prices of pHA per dressing change from the wound care center perspective. The following time points were assessed: 90, 60, and 30 days. Dressing changes occurred every 2.5 days. Sensitivity analysis was performed to gauge the robustness of the results. RESULTS: A total of 31 patients (68% women) with 31 lesions (average age of wound, 29 months; range, 1-240 months) were included in the clinical study. Re-epithelialization occurred in 23 lesions (74%) at 90 days, 17 (55%) at 60 days, and 3 (10%) at 30 days. The total CPRs were $75.69, $68.27, and $193.44, and the per-day CPRs were $0.84, $1.13, and $6.45 at 90, 60, and 30 days, respectively. The sensitivity analysis revealed that CPRs ranged from $0.63 to $1.12 per day at 90 days. CONCLUSIONS: Incorporating pHA into standard wound healing protocols is a minimal added expense and may yield a substantial economic savings of $2,695 at 90 days.

Health Economic Analysis of Two-Layer Bandage System for Treatment of Chronic Venous Insufficiency.

Background: Compression therapy is the gold standard for the treatment of chronic venous insufficiency (CVI). Two-layer bandage (2LB) systems have been shown to be a safe and effective treatment option. Objective: To estimate the total cost per response (CPR) for the resolution of edema and wounds in patients with CVI treated with a 2LB system as part of their overall wound healing regimen. Methods: A probabilistic decision tree model was developed to estimate the incremental CPR for a 2LB system. The model simulated 10 000 patients to estimate the CPR for the resolution of edema and wound healing. The analysis was performed using clinical data from a published single-arm, multicenter prospective study of CVI indicated for compression therapy. The response outcomes of interest were resolution of edema and rate of wound healing. The follow-up time was a maximum of 6 weeks, and the perspective of the study was a US outpatient treatment center. Economic data for compression therapy were based on the public prices of a 2LB system. Dressing changes occurred per manufacturer instructions for use. Results: The study comprised 702 patients (56% female), with a total of 414 wounds. The median duration of the wounds was 42 days, and the median size at the initial visit was 3.5 cm2. The average pain reduction fell by 67% using a visual analog score. Bandages were typically changed once or twice a week (51.7%). Wound healing occurred in 128 of the 414 wounds (30.9%). The expected incremental CPR of a 2LB system for the resolution of edema was $65.67 (range, $16.67-$124.32). The expected incremental CPR of a 2LB system for the healing of a wound was $138.71 (range, $35.71-$273.53). Conclusion: This economic evaluation complements previous clinical effectiveness and safety studies of 2LB systems for the treatment of CVI. The results demonstrate that the costs of incorporating 2LB into standard wound-healing protocols are negligible compared with overall treatment costs. Two-layer bandages may be considered a cost-effective first-line system for the treatment of wounds caused by CVI.

Time and labor costs of compression therapy wrap system for lower extremity edema: results from a single center.

INTRODUCTION: Compression therapy is the standard of care for the treatment of lower extremity edema. However, compression therapy systems can be time-consuming to apply, which adds costs to the health care system and further strains human resources. OBJECTIVE: The purpose of this study was to assess time and labor costs associated with the application of a 2LB versus 4LB compression therapy system. MATERIALS AND METHODS: Time and labor cost data associated with the application of a 2LB system for the treatment of lower extremity edema of all etiologies were collected from a single high-volume wound care center located in Dayton, Ohio. The time and labor costs were compared to a 4LB system over the course of a single day (n = 38). RESULTS: The application time and associated costs were 50% lower for the 2LB system. The expected savings of a 2LB compression system over the course of a month was 16:27 hours and $427 compared to a 4LB compression system, and the revenue gain was estimated at $15 210 revenue per month over the course of the month for the practice. CONCLUSION: The use of a 2LB compression system may be associated with substantial time and cost savings compared to a 4LB system.

The High Cost of Death After Acute Myocardial Infarctions: Results from a National US Hospital Database.

Introduction: This study described the differences in costs and length of stay (LOS) among patients with AMI who died versus survived using a large, nationally representative cohort of AMI patients. Methods: The 2019 HCUP NIS was used to analyze costs, and LOS among all patients with a principal diagnosis of AMI. A propensity-score matched analysis and multivariable regression were used to adjust for patient and hospital characteristics. Results: There were 4559 visits in each of the cohorts (total 9118). The adjusted mean hospital cost was $18,970 (95% CI $16,453 - $21,871) for those that survived and $23,173 (95% CI $20,167 - $26,626; p <0.001) for those that died. The LOS was 3.95 (95% CI 3.41-4.57) in survivors and 4.24 (95% CI 3.67-4.89; p <0.001) in those who died. Conclusion: Survivors of AMI incurred lower costs and length of stay than those who died. Higher costs were attributed to greater LOS and higher-level care. The results suggest that economic evaluations of cardiovascular interventions that do not include the cost of dying may underestimate the benefits of the intervention.

A Retrospective Health Economic Analysis of a Stable Hypochlorous Acid Preserved Wound Cleanser Versus 0.9% Saline Solution as Instillation for Negative-Pressure Wound Therapy in Severe and Infected Wounds.

Introduction Negative-pressure wound therapy (NPWT) with instillation and dwell time is an accepted adjunct therapy for infected wounds. A study was conducted to assess whether the use of hypochlorous acid preserved wound cleanser (HAPWOC) (Vashe, Urgo Medical North America, Fort Worth, TX, USA) as the irrigant would reduce the cost of care in comparison to 0.9% saline (NaCl). Method A comparative, observational, retrospective analysis assessed 27 serious and infected wounds in 24 patients. The lesions were of different and complex etiologies, including necrotizing fasciitis and stage IV diabetic foot ulcers. NPWT was used as part of the overall multimodal treatment regimen. The only variance in the treatment protocol was the use of saline (N=8) or HAPWOC (N=19) as the irrigant. Results When compared to NaCl, wounds treated with HAPWOC trended toward fewer operating room (OR) visits versus NaCl (3.3 versus 4.1) and a shorter length of hospital stay (LOS) (24.3 days versus 37.9 days). The Orlando Health Transparency guide shows the cost of OR debridement as $2,525. Thus, debridement for HAPWOC-treated wounds ($8,332) costs $2,020 (24%) less than for NaCl-treated wounds ($10,352). Using the 2016 Kaiser Health data (average daily hospital cost, excludingall interventions: $2,052), the cost of HAPWOC and NaCl instill translates to $49,864 and $77,771, respectively, a difference of $27,906 (56%) more for NaCl treatment. The Agency for Healthcare Research and Quality (AHRQ) 2012 data indicate an average daily cost of hospital stay, including all interventions, of $10,400. Thus, HAPWOC treatment cost translates to $252,720 versus NaCl-related costs of $394,160; in these calculations, using NaCl costs $141.440 (+56%) more per patient than HAPWOC. Conclusion The use of NPWT with HAPWOC versus NaCl as instillation in NPWT reduces the number of visits to the operating room and LOS. This has a significant impact on lowering the cost of care when HAPWOC is used.

Cost-effectiveness of catheter ablation versus medical therapy for the treatment of atrial fibrillation in the United Kingdom.

INTRODUCTION: Research evidence has shown that catheter ablation is a safe and superior treatment for atrial fibrillation (AF) compared to medical therapy, but real-world practice has been slow to adopt an early interventional approach. This study aims to determine the cost effectiveness of catheter ablation compared to medical therapy from the perspective of the United Kingdom. METHODS: A patient-level Markov health-state transition model was used to conduct a cost-utility analysis. The population included patients previously treated for AF with medical therapy, including those with heart failure (HF), simulated over a lifetime horizon. Data sources included published literature on utilization and cardiovascular event rates in real world patients, a systematic literature review and meta-analysis of randomized controlled trials for AF recurrence, and publicly available government data/reports on costs. RESULTS: Catheter ablation resulted in a favorable incremental cost-effectiveness ratio (ICER) of £8614 per additional quality adjusted life years (QALY) gained when compared to medical therapy. More patients in the medical therapy group failed rhythm control at any point compared to catheter ablation (72% vs. 24%) and at a faster rate (median time to treatment failure: 3.8 vs. 10 years). Additionally, catheter ablation was estimated to be more cost-effective in patients with AF and HF (ICER = £6438) and remained cost-effective over all tested time horizons (10, 15, and 20 years), with the ICER ranging from £9047-£15 737 per QALY gained. CONCLUSION: Catheter ablation is a cost-effective treatment for atrial fibrillation, compared to medical therapy, from the perspective of the UK National Health Service.

Cost-Effectiveness of Hypochlorous Acid Preserved Wound Cleanser versus Saline Irrigation in Conjunction with Ultrasonic Debridement for Complex Wounds.

Objective: Low-frequency ultrasound debridement with irrigation is an effective method of wound bed preparation. A recent clinical study compared hypochlorous acid preserved wound cleanser (HAPWOC) to saline and found HAPWOC to be a more effective adjunct to low frequency ultrasound debridement. However, HAPWOC has an added cost. The primary objective of this study was to assess the cost-effectiveness of HAPWOC as an irrigation modality with low-frequency ultrasound debridement for the treatment of severely complex wounds that were destined to be closed primarily via a flap. The secondary objective of this study was to estimate the number needed to treat (NNT) to avoid a wound-related complication and its expected cost per NNT. Methods: A patient-level Monte-Carlo simulation model was used to conduct a cost-effectiveness analysis from the US health system perspective. All clinical data were obtained from a prospective clinical trial. Cost data were obtained from the publicly available data sources in 2021 US dollars. The effect measure was the avoidance of wound-related complications at 14-days post-debridement. The primary outcome was the incremental cost-effectiveness ratio (ICER), a measure of the additional cost per benefit. The secondary outcomes were the NNT and expected cost per NNT to avoid one complication (complementary to the ICER in assessing cost-effectiveness). Deterministic and probabilistic sensitivity analyses (PSA) were performed to gauge the robustness and reliability of the results. Results: The ICER for HAPWOC versus saline irrigation was US$90.85 per wound complication avoided. The expected incremental cost per patient in the study and effect was US$49.97 with 55% relative reduction in wound-related complications at day 14 post debridement procedure. The NNT and cost per NNT were 2 and US$99.94, respectively. Sensitivity analyses demonstrated that these results were robust to variation in model parameters. Conclusion: HAPWOC was a cost-effective strategy for the treatment of complex wounds during ultrasonic debridement. For every two patients treated with HAPWOC, one complication was avoided.

Identifying priority and bright spot areas for improving diabetes care: a geospatial approach.

The objective of this study was to describe a novel geospatial methodology for identifying poor-performing (priority) and well-performing (bright spot) communities with respect to diabetes management at the ZIP Code Tabulation Area (ZCTA) level. This research was the first phase of a mixed-methods approach known as the focused rapid assessment process (fRAP). Using data from the Lehigh Valley Health Network in eastern Pennsylvania, geographical information systems mapping and spatial analyses were performed to identify diabetes prevalence and A1c control spatial clusters and outliers. We used a spatial empirical Bayes approach to adjust diabetes-related measures, mapped outliers and used the Local Moran's I to identify spatial clusters and outliers. Patients with diabetes were identified from the Lehigh Valley Practice and Community-Based Research Network (LVPBRN), which comprised primary care practices that included a hospital-owned practice, a regional practice association, independent small groups, clinics, solo practitioners and federally qualified health centres. Using this novel approach, we identified five priority ZCTAs and three bright spot ZCTAs in LVPBRN. Three of the priority ZCTAs were located in the urban core of Lehigh Valley and have large Hispanic populations. The other two bright spot ZCTAs have fewer patients and were located in rural areas. As the first phase of fRAP, this method of identifying high-performing and low-performing areas offers potential to mitigate health disparities related to diabetes through targeted exploration of local factors contributing to diabetes management. This novel approach to identification of populations with diabetes performing well or poor at the local community level may allow practitioners to target focused qualitative assessments where the most can be learnt to improve diabetic management of the community.

Cost-utility analysis of single nucleotide polymorphism panel-based machine learning algorithm to predict risk of opioid use disorder.

Aim: To conduct a cost-utility analysis of a novel genetic diagnostic test (OUDTEST) for risk of developing opioid use disorder for elective orthopedic surgery patients. Materials & Methods: A simulation model assessed cost-effectiveness and quality-adjusted life-years (QALYs) for OUDTEST from private insurer and self-insured employer perspectives over a 5-year time horizon for a hypothetical patient population. Results: OUDTEST was found to cost less and increase QALYs, over a 5-year period for private insurance (savings US$2510; QALYs 0.02) and self-insured employers (-US$2682; QALYs 0.02). OUDTEST was a dominant strategy in 71.1% (private insurance) and 72.7% (self-insured employer) of model iterations. Sensitivity analyses revealed robust results except for physician compliance. Conclusion: OUDTEST was expected to be a cost-effective solution for personalizing postsurgical pain management in orthopedic patients.

Hospital Admissions Associated With Cancer Pain in Older Adults With and Without Dementia.

BACKGROUND: Neoplasm-related pain is often suboptimally treated, contributing to avoidable suffering and increased medical resource use and costs. We hypothesized that dementia may contribute to increased resource use and costs in patients hospitalized for neoplasm-related pain in the United States. AIMS: To examine how persons with cancer and dementia use medical resources and expenditures in US hospitals compared to ondividuals without dementia. DESIGN: This study examined a retrospective cohort. SETTING: Admissions to US hospitals for neoplasm-related pain from 2012-2016 PARTICIPANTS/SUBJECTS: METHODS: Data were obtained from the 2012-2016 National Inpatient Sample (NIS). The sample included hospital admissions of individuals aged 60 or older with a primary diagnosis of neoplasm-related pain. Dementia was defined using the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM), and ICD-10-CM diagnosis codes. Primary outcomes were number of admissions, costs, and length of stay (LOS). Descriptive statistics and multivariable regression models were used to examine the relationships among dementia, costs, and LOS. RESULTS: Of 12,034 admissions for neoplasm-related pain, 136 (1.1%) included a diagnosis of dementia and 11,898 (98.9%) did not. Constipation was present in 13.2% and 24.5% of dementia and nondementia admissions, respectively. The median LOS was 4 days in persons with dementia and three in those without. Mean costs per admission were higher in persons without dementia ($10,736 vs. $9,022, p = .0304). In adjusted regression results, increased costs were associated with nonelective admissions and longer LOS, and decreased costs with age above the mean. In contrast, decreased LOS was associated with age above the mean and nonelective admissions. Dementia was associated with neither endpoint. CONCLUSION: This study provides nurses and other health care professionals with data to further explore opportunities for improvement in cancer pain management in patients with and without dementia that may optimize use of medical resources.

Estimates of the value of life lost from COVID-19 in Ohio.

The economic burden of mortality due to the novel coronavirus (COVID-19) extends beyond the lives lost. Data from the Ohio Department of Public Health and Social Security Administration was used to estimate the years of potential life lost, 72,274 and economic value of those lost lives, US$17.39 billion. These estimates may be used to assess the risk-trade off of COVID-19 mitigation strategies in Ohio.

Economic Analysis of the European Healthcare Burden of Sternal-Wound Infections Following Coronary Artery Bypass Graft.

Background: Sternal wound infections (SWIs) can be some of the most complex surgical-site infections (SSIs) and pose a considerable risk following coronary artery bypass graft surgery (CABG). Objective: To capture the cost burden of SWIs following CABG across European countries. Methods: We modeled a standardized care pathway for CABG, starting at the point of surgery and extending to 1-year post surgery. The Markov model captures the incidence and cost of an SWI (deep or superficial SWIs). The cost burden is calculated from a hospital perspective such that the main inputs relating to costs were intensive-care-unit (ICU) and general-ward (GW) days. Outpatient care, not in the hospital setting, has no cost in this analysis. Model input parameters were taken from Eurostat and a review of published, peer-reviewed literature. European countries were included in this analysis when values for 50% of the required input parameters per country were identified. Missing data points were interpolated from available data. The robustness of results was assessed via probabilistic sensitivity analysis. Results: Full required input data were available for 8 European countries; a further 18 countries had sufficient data for analysis. The median (interquartile range) for SWI incidence across the 26 countries was 3.9% (2.9-5.6%). The total burden for all 26 countries of SWIs after CABG was €170.8 million. These costs were made up of 25,751 additional ICU days, 137,588 additional GW days, and 7,704 readmissions. The mean cost of an SWI ranged from €8,924 in Poland to €21,321 in Denmark. Relative to the costs of post-CABG care without an SWI complication, the incremental cost of an SWI was highest in Greece (24.9% increase) and lowest in the UK (3.8% increase) with a median (interquartile range) of 12% (10-16%) across all 26 countries. Conclusions: SWIs following CABG present a considerable burden to healthcare budgets.

Cost-minimization analysis of negative pressure wound therapy technologies for the treatment of moderate-to-severe foot infections.

Aim: The objective was to estimate the cost of care associated with two negative pressure wound therapy (NPWT) technologies used to treat patients admitted to the hospital with moderate-to-severe foot infections. Materials & methods: A decision tree simulation model was developed to estimate the hospital costs associated with two different NPWT technologies: Cardinal Health™ PRO (NPWT-C) and V.A.C. ULTA™ (NPWT-K). Clinical data were obtained from a previously completed single-site prospective trial. One-way and probabilistic sensitivity analyses were performed to gauge the robustness of the results. Results: The total expected per-patient costs were US$41,206 (SD: US$8,194) for NPWT-C and US$44,439 (SD: US$8,963) for NPWT-K. Conclusion: This study found that NPWT-C was expected to minimize the total costs over the episode of treatment. Larger and more clinically diverse studies are recommended to confirm these findings.

Outcomes of Hospitalized COVID-19 Patients by Risk Factors: Results from a United States Hospital Claims Database.

BACKGROUND/OBJECTIVE: The primary objective was to quantify the role of the number of Centers of Disease Control and Prevention (CDC) risk factors on in-hospital mortality. The secondary objective was to assess the associated hospital length of stay (LOS), intensive care unit (ICU) bed utilization, and ICU LOS with the number of CDC risk factors. METHODS: A retrospective cohort study consisting of all hospitalizations with a confirmed COVID-19 diagnosis discharged between March 15, 2020 and April 30, 2020 was conducted. Data was obtained from 276 acute care hospitals across the United States. Cohorts were identified based upon the number of the CDC COVID-19 risk factors. Multivariable regression modeling was performed to assess outcomes and utilization. The odds ratio (OR) and incidence rate ratio (IRR) were reported. RESULTS: Compared with patients with no CDC risk factors, patients with risk factors were significantly more likely to die during the hospitalization: One risk factor (OR 2.08, 95% CI, 1.60-2.70; P < 0.001), two risk factors (OR 2.63, 95% CI, 2.00-3.47; P < 0.001), and three or more risk factors (OR 3.49, 95% CI, 2.53-4.80; P < 0.001). The presence of CDC risk factors was associated with increased ICU utilization, longer ICU LOS, and longer hospital LOS compared to those with no risk factors. Patients with hypertension (OR 0.77, 95% CI, 0.70-0.86; P < 0.001) and those administered statins were less likely to die (OR 0.54, 95% CI, 0.49-0.60; P < 0.001). CONCLUSIONS: Quantifying the role of CDC risk factors upon admission may improve risk stratification and identification of patients who may require closer monitoring and more intensive treatment.

Sternal-Wound Infections following Coronary Artery Bypass Graft: Could Implementing Value-Based Purchasing be Beneficial?

BACKGROUND/OBJECTIVES: Sternal-wound infections (SWIs) are rare but consequential healthcare-healthcare-associated infections following coronary artery bypass graft surgery (CABG). The impact of SWIs associated on the cost of health care provision is unknown. The aim of this study was to quantify the burden of CABG-related SWIs across countries with mature health care systems and estimate value-based purchasing (VBP) levels based on the local burden. METHODS: A structured literature review identified relevant data for 14 countries (the Netherlands, France, Germany, Austria, the United Kingdom, Canada, Italy, Japan, Spain, the United States, Brazil, Israel, Taiwan, and Thailand). Data, including SWI rates, CABG volume, and length of stay, were used to populate a previously published Markov model that simulates the patient's CABG-care pathway and estimates the economic (US$) and care burden of SWIs for each country. Based on this burden, scenarios for VBP were explored for each country. A feasible cost of intervention per patient for an intervention providing a 20% reduction in the SWI rate was calculated. RESULTS: The SWI burden varied considerably between settings, with SWIs occurring in 2.8% (the United Kingdom) to 10.4% (the Netherlands) of CABG procedures, while the costs per SWI varied between US$8172 (Brazil) to US$54 180 (Japan). Additional length of stay after SWI was the largest cost driver. The overall highest annual burden was identified in the United States (US$336 million) at a mean cost of US$36 769 per SWI. Given the SWI burden, the median cost of intervention per patient that a hospital could afford ranged from US$20 (US$13 to US$42) in France to US$111 (US$65 to US$183) in Japan. CONCLUSIONS: SWIs represent a large burden with a median cost of US$13 995 per case and US$900 per CABG procedure. By tackling SWIs, there is potential to simultaneously reduce the burden on health care systems and improve outcomes for patients. Mutually beneficial VBP agreements might be one method to promote uptake of novel methods of SWI prevention.

When Second Best Might Be the Best: Using Hospitalization Data to Monitor the Novel Coronavirus Pandemic.

The novel coronavirus' high rate of asymptomatic transmission combined with a lack of testing kits call for a different approach to monitor its spread and severity. We proposed the use of hospitalizations and hospital utilization data to monitor the spread and severity. A proposed threshold of a declining 7-day moving average over a 14-day period, "7&14" was set to communicate when a wave of the novel coronavirus may have passed. The state of Ohio was chosen to illustrate this threshold. While not the ideal solution for monitoring the spread of the epidemic, the proposed approach is an easy to implement framework accounting for limitations of the data inherent in the current epidemic. Hospital administrators and policy makers may benefit from incorporating this approach into their decision making.
