RESUMO
Objectives: To determine the cost of two surgical treatment approaches for vulvar Paget's disease and model the cost-effectiveness considering differences in recurrence and reoperation over time. Methods: We assessed cost-effectiveness between excision guided by Mohs micrographic surgery (MMS-E) and traditional wide local excision (WLE). We examined billing data from patients with vulvar Paget's disease who underwent MMS-E (cases, n = 24, 2018-2022) or WLE (controls, n = 64, 1990-2020). We created typical treatment bundles incorporating physician-administered services and facility costs standardized to Medicare reimbursements in 2022 United States Dollars (USD). The primary measure of effectiveness was disease-free years of life. A secondary analysis estimated quality-adjusted life years (QALY). A Markov model simulated treatment pathways over a 10-year time horizon. Transition probabilities were based on institutional recurrence rates (3-year RR 6.7 % for MMS-E vs 34.1 % for WLE). We used a willingness-to-pay threshold of 100,000 USD per QALY. Results: The cost of a single surgical episode was 34,664 USD for MMS-E and 14,969 USD for WLE. In the setting of lower recurrence rates with MMS-E, the incremental cost was 12,789 USD per disease-free year gained. A secondary analysis incorporating QALY showed an incremental cost of 72,820 USD per QALY. Conclusions: MMS-E appears to be a cost-effective treatment for vulvar Paget's disease compared to historic standard of care. Our ability to estimate quality of life gained by avoiding disease recurrence was limited by scant data for this rare condition; thus, future studies incorporating health utility values are needed to facilitate a more comprehensive analysis.
RESUMO
OBJECTIVE: This study aims to assess the costs of a Same-Day Discharge Enhanced Recovery Pathway (SDD) for diverting loop ileostomy closure compared to a standard institutional enhanced recovery protocol (ERP). SUMMARY BACKGROUND DATA: Every year, 50,155 patients in the United States undergo temporary stoma reversal. While ambulatory stoma closure has shown promise, widespread adoption remains slow. This study builds on previous research, focusing on the costs of a novel SDD protocol introduced in 2020. METHODS: A retrospective case-control study was conducted at Mayo Clinic, Rochester, Minnesota, and Mayo Clinic, Jacksonville, Florida, comparing patients undergoing same-day discharge diverting loop ileostomy closure (SDD) from August 2020 to February 2023 to those in a matched cohort receiving standard inpatient ERP. Patients were matched based on age, sex, ASA score, surgery period, and hospital. Primary outcomes included direct hospitalization and additional costs in the 30 days post-discharge. RESULTS: The SDD group (n=118) demonstrated a significant reduction in median index episode hospitalization and 30-day post-operative costs compared to the inpatient group (n=236), with savings of $4,827 per patient. Complication rates were similar, and so were readmission and reoperation rates. CONCLUSIONS: Implementation of the SDD for diverting loop ileostomy closure is associated with substantial cost savings without compromising patient outcomes. The study advocates for a shift towards same-day discharge protocols, offering economic benefits and potential improvements in healthcare resource utilization.
RESUMO
BACKGROUND: The Surgery in Early Metastatic Seminoma (SEMS) trial examined retroperitoneal lymph node dissection as first-line treatment for patients with isolated 1-3 cm retroperitoneal lymphadenopathy. To date, the standard of care for these patients has been either chemotherapy or radiotherapy. Herein, we evaluated the relative cost-effectiveness of these management strategies. METHODS: A microsimulation model assessed the cost-effectiveness of retroperitoneal lymph node dissection, chemotherapy, and radiotherapy for stage IIA seminoma. Sensitivity analyses were performed to evaluate model robustness. Retroperitoneal lymph node dissection recurrence probabilities were obtained from the SEMS trial. All other probability and utility values were obtained from published literature. Primary outcomes included costs from a commercial insurer's perspective, effectiveness (quality adjusted life-years [QALYs]), and incremental cost-effectiveness ratios using a willingness-to-pay threshold of $100â000/QALY. RESULTS: At a lifetime horizon, the mean costs per patient for retroperitoneal lymph node dissection, radiotherapy, and chemotherapy were $58â469, $98â783, and $104â096, and the mean QALYs were 40.61, 40.70, and 39.15, respectively. Retroperitoneal lymph node dissection was found to be the most cost-effective approach because of high costs and accrued disutility of chronic toxicities associated with radiotherapy (cost-effectiveness ratios = $433â845/QALY) and chemotherapy (dominated). On 1-way sensitivity analyses, retroperitoneal lymph node dissection was no longer cost-effective if the probabilities of infertility and cardiovascular toxicity after radiotherapy were less than 13% and 16%, respectively, or if the 2-year probability of progression after retroperitoneal lymph node dissection was more than 26%. CONCLUSIONS: Retroperitoneal lymph node dissection was the most cost-effective treatment approach for stage IIA seminoma. These findings support clinical guideline consideration of including retroperitoneal lymph node dissection as a treatment option for well-selected patients with stage IIA seminoma.

BACKGROUND: The financial burden linked to the diagnosis and treatment of patients with chest pain on the health care system is considerable. Angina and nonobstructive coronary artery disease (ANOCA) is common, associated with adverse cardiovascular events, and may lead to repeat testing or hospitalizations. Diagnostic certainty can be achieved in patients with ANOCA using coronary reactivity testing (CRT); however, its financial effect on the patient has not been studied. Our goal was to assess the effect of CRT on health care-related cost in patients with ANOCA. METHODS: Patients with ANOCA who underwent diagnostic coronary angiography (CAG) and CRT (CRT group) were matched to controls who had similar presentation but only underwent a CAG without CRT (CAG group). Standardized inflation-adjusted costs were collected and compared between the 2 groups on an annual basis for 2 years post the index date (CRT or CAG). RESULTS: Two hundred seven CRT and 207 CAG patients were included in the study with an average age of 52.3±11.5 years and 76% females. The total cost was significantly higher in the CAG group as compared with the CRT group ($37 804 [$26 933-$48 674] versus $13 679 [$9447-$17 910]; P<0.001). When costs are itemized and divided based on the Berenson-Eggers Type of Service categorization, the largest cost difference occurred in imaging (any type, including CAG; P<0.001), procedures (eg, percutaneous coronary intervention/coronary artery bypass grafting/thrombectomy) (P=0.001), and test (eg, blood tests, EKG; P<0.001). CONCLUSIONS: In this retrospective observational study, assessment of CRT in patients with ANOCA was associated with significantly reduced annual total costs and health care utilization. Therefore, the study may support the integration of CRT into clinical practice.

STUDY OBJECTIVE: Increasing evidence suggests that hysterectomy to treat uterine fibroids (UFs), even with ovarian conservation (OC), is associated with a 33% increased risk of coronary artery disease (CAD). We sought to compare the cost-effectiveness of various treatment approaches for UFs to understand the trade-offs among development of CAD vs new fibroids. DESIGN: We developed a Markov model to include women with UFs who no longer desired pregnancy. The outcomes of interest were quality-adjusted life-years (QALYs) and total treatment costs. We conducted sensitivity analyses to test the effect of uncertain model inputs. SETTING: Health system perspective. PATIENTS: A hypothetical cohort of 10 000 40-year-old women. INTERVENTIONS: Myomectomy, hysterectomy with OC, and hysterectomy without OC. MEASUREMENTS AND MAIN RESULTS: Myomectomy was the best-value strategy, costing US$528 217 and providing 19.38 QALYs. Neither hysterectomy with OC nor hysterectomy without OC was found to be cost-effective, assuming a willingness-to-pay threshold of $100 000 per QALY gain as hysterectomy with OC provided more benefit than myomectomy at an average cost of $613 144 to gain one additional QALY. The sensitivity analyses showed that if the risk of new symptomatic UFs that required treatment after myomectomy was more than 13%, annually (base case, 3.6%), or the quality of life after myomectomy was less than 0.815 (base case, 0.834), then myomectomy would no longer be cost-effective, under a willingness-to-pay amount of US$100 000. CONCLUSION: Myomectomy is an optimal treatment of UFs compared with hysterectomy among women aged 40 years. The increased risk of CAD after hysterectomy and its associated costs and the effects on morbidity and quality of life made hysterectomy a costlier and less effective long-term strategy.

OBJECTIVES: To conduct comparative cost analysis of hospital care for critically ill patients with Limited English Proficiency (LEP) versus patients with English proficiency (controls). PATIENTS AND METHODS: We conducted a historical cohort study using propensity matching at Mayo Clinic Rochester, a quaternary care academic center. We included hospitalized patients who had at least one admission to ICU during a 10-year period between 1/1/2008-12/31/2017. RESULTS: Due to substantial differences in baseline characteristics of the groups, propensity matching for the covariates age, sex, race, ethnicity, APACHE 3 score, and Charlson Comorbidity score was used, and we achieved the intended balance. The final cohort included 80,404 patients, 4,246 with LEP and 76,158 controls. Patients with LEP had higher costs during hospital admission to discharge, with a mean cost difference of $3861 (95% CI $822 to $6900, p = 0.013) and also higher costs during index ICU admission to hospital discharge, with a mean cost difference of $3166 (95% CI $231 to $6101, p = 0.035). A propensity matched cohort including only those that survived showed those with LEP had significantly greater mean costs for all outcomes. Sensitivity analysis revealed that international patients with LEP had significantly greater overall hospital costs of $9,240 than patients with LEP who resided in the US (95% CI $3341 to $15,140, p = 0.002). CONCLUSION: This is the first study to demonstrate significantly higher costs for patients with LEP experiencing a critical illness. The causes for this may be increased healthcare utilization secondary to communication deficiencies that impede timely decision making about care.

BACKGROUND: Yttrium-90 ibritumomab tiuxetan [(90)Y-IT] is a CD20-targeted radio-immunotherapeutic agent. It has shown an excellent therapeutic activity with high tolerability against previously untreated follicular lymphoma (FL) and marginal zone B cell lymphoma (MZL). It is an attractive therapeutic option as the treatment schedule is short and convenient. The aim of our study is to determine the cost-effectiveness of (90)Y-IT in comparison to the standard-of-care bendamustine + rituximab (BR) in the first-line treatment of low-grade FL (LG-FL) and MZL in the real world. PATIENTS AND METHODS: We included all patients who were treated with standard-dose (90)Y-IT for previously untreated LG-FL and MZL at the Mayo Clinic Cancer Center (N = 51). A comparator arm with a historical cohort of previously untreated LG-FL and MZL patients who received BR was used (N = 92). RESULTS: Inverse propensity weighting was utilized to balance the 2 study arms. There were no differences in terms of overall response rate (100% vs. 98%, P = .18), complete response rate (94% vs. 95%, P = .91), or 5 years progression-free survival (76% vs. 75%, P = .63) between patients who received (90)Y-IT and BR, respectively. Within the first year, patients who received (90)Y-IT required an average of 4.5 fewer oncology clinic visits (P < .001), an average of 10 fewer days of therapeutic use (P < .001), and 40% less use of growth factors (P < .001) as compared to the BR group. The direct therapeutic cost of (90)Y-IT treatment was 54% less than that of 6 cycles of BR. CONCLUSION: The findings suggest that (90) Y-IT is more cost-effective than BR and is a viable alternative in up-front management of LG-FL and MZL.

INTRODUCTION: True penicillin allergy is rare and is commonly incorrectly reported. In fact, less than five percent of patients who report a penicillin allergy will have a currently active clinically-significant IgE- or T-cell-mediated hypersensitivity when appropriately tested. Penicillin is the agent of choice for intrapartum antibiotic prophylaxis to reduce the risk of group B streptococcus early-onset disease in the newborn. Inaccurate penicillin allergy status may lead to inappropriate antibiotic use, as most alternative drugs are more expensive and broader spectrum than penicillin. Penicillin allergy testing has been found to be safe in pregnancy and cost-effective in other patient populations. OBJECTIVE: To evaluate the cost-effectiveness of penicillin allergy testing and appropriate antibiotic treatment (test then treat strategy) compared to usual care among pregnant women. METHODS: We developed a decision tree to evaluate the cost of providing appropriate care via a test then treat strategy for pregnant women who report a penicillin allergy, compared to usual care. RESULTS: Using the test then treat strategy the additional cost to ensure appropriate care for all pregnant women who report a penicillin allergy, was $1122.38 per person. Adopting a test then treat strategy increased the number of appropriate antibiotic use from 7,843/10,000 to 10,000/10,000 simulations. CONCLUSION: Our results show that a test then treat strategy for pregnant women who report a penicillin allergy is a good-value intervention.

BACKGROUND: The Merlin assay for melanoma-risk assessment has become commercially available to reduce the rate of unnecessary sentinel lymph node biopsies (SLNB) in SLNB-eligible patients with cutaneous melanoma. Merlin low-risk patients are recommended to undergo wide local excision (WLE) of the primary tumor, whereas Merlin high-risk patients are recommended to undergo both SLNB and WLE. Here, we compared the cost of a Merlin testing strategy to that of a no-testing strategy (usual care) before prescribing SLNB. METHODS: We identified T1 and T2 patients who underwent WLE and SLNB but not completion lymph node dissection between 2007 and 2018. Controls were T1 patients who only underwent WLE. Costs for WLE and SLNB were calculated by converting institutional cost data to standardized Medicare reimbursement rates. We then developed a decision tree to compare the cost of Merlin testing to that of a no-testing strategy (usual care). RESULTS: The average standardized cost of WLE was $2066, whereas the cost of WLE and SLNB was $11,976 based on Medicare rates. At a cost below $7350 for T1b melanoma and $4600 for T1b to T2 melanoma, Merlin testing was cost-saving compared to a no-testing strategy (usual care), assuming Medicare reimbursement rates. CONCLUSION: Merlin testing for T1b and T2 melanoma is potentially cost saving depending on the cost of the molecular assay and SLNB reimbursement rates. In addition to being cost saving, Merlin is expected to improve health-related quality of life.

BACKGROUND: The VESPER trial demonstrated improved progression-free (PFS) and (preliminarily) overall survival (OS) with six cycles of neoadjuvant dose-dense methotrexate, vinblastine, doxorubicin, and cisplatin (ddMVACx6) versus four cycles of gemcitabine and cisplatin (GCx4) before radical cystectomy (RC) for muscle-invasive bladder cancer (MIBC), but with increased toxicity. This study compares the cost-effectiveness of these regimens. METHODS: A cost-effectiveness analysis of neoadjuvant ddMVACx6 and GCx4 was performed using a decision-analytic Markov model with 5-year, 10-year, and lifetime horizons. Probabilities were derived from reported VESPER data. Utility values were obtained from the literature. Primary outcomes were effectiveness measured in quality-adjusted life years (QALY) and incremental cost-effectiveness ratio (ICER) with a willingness to pay threshold of $100,000 per QALY. One-way and probabilistic sensitivity analyses were performed to evaluate the robustness of the model. RESULTS: At 5 years, ddMVACx6 improved QALYs by 0.30 at an additional cost of $16,100, rendering it cost-effective relative to GCx4 (ICER: $53,284/QALY). Additionally, probabilistic sensitivity analysis found ddMVACx6 to be cost-effective in 79% and 81% of microsimulations at10-year and lifetime horizons, respectively. One-way sensitivity analysis demonstrated a minimum difference in 5-year progression of 0.9% and progression mortality of 0.7% between ddMVACx6 and GCx4 was necessary for ddMVACx6 to remain cost-effective. CONCLUSIONS: Neoadjuvant ddMVACx6 was more cost-effective than GCx4 for MIBC. These data, together with the improved PFS and (albeit preliminary) OS noted in VESPER, support use of this regimen in appropriate candidates for neoadjuvant chemotherapy before RC. LAY SUMMARY: We performed a benefit-to-cost analysis using evidence from a randomized controlled trial that compared two different chemotherapy treatments before bladder removal for bladder cancer that had invaded into the bladder muscle. Despite being more expensive and having a greater likelihood of toxicity, six cycles of dose-dense methotrexate, vinblastine, doxorubicin, and cisplatin was more cost-effective (or had higher value) than four cycles of gemcitabine and cisplatin.

OBJECTIVES: Pancreas transplant is the only treatment that establishes normal glucose levels for patients diagnosed with diabetes. We analyzed the outcome of pancreas transplant alone (PTA) versus standard of care in the United States from 2008 to 2018. We also developed an economic model to analyze the cost-effectiveness of pancreas transplant versus continuing standard of care. METHODS: We used the Scientific Registry of Transplant Recipients database and analyzed PTA recipient survival. Using those results, we developed a Markov model that followed a cohort of 40-year-old patients with type 1 diabetes over a 10-year time horizon. The primary outcomes were (i) the survival benefit of a pancreas transplant, (ii) quality-adjusted life-years (QALYs), and (iii) total costs. RESULTS: We found no difference in survival advantage of PTA compared with standard of care (hazard ratio, 1.09; 95% confidence interval, 0.56-2.14). However, pancreas transplant ($172,823, 6.87 QALY) was cost-saving compared with standard of care ($232,897, 6.04 QALY) for type 1 diabetes. Pancreas transplantation was cost-effective in 95% of 10,000 simulations in probabilistic sensitivity analysis, using a $100,000/QALY willingness-to-pay threshold. CONCLUSIONS: Although there is no difference in survival for PTA compared with standard of care, PTA is a cost-saving therapy for type 1 diabetes.

Introduction: Teleneonatology (TN) allows remote neonatologists to provide real-time audio-video telemedicine support to community hospitals when neonates require advanced resuscitation or critical care. Currently, there are no published economic evaluations of U.S. TN programs. Objective: To evaluate the cost of TN from the perspective of the health care system. Methods: We constructed a decision tree comparing TN to usual care for neonates born in hospitals without a neonatal intensive care unit (NICU) who require consultation. Our outcome of interest was total cost per patient, which included the incremental cost of a TN program, the cost of medical transport, and the cost of NICU or non-NICU hospitalization. We performed threshold sensitivity analyses where we varied each parameter to determine whether the base-case finding reverted. Results: For neonates requiring consultation after birth in a hospital without a NICU, TN was less costly ($16,878) than usual care ($28,047), representing a cost-savings of $11,168 per patient. Sensitivity analyses demonstrated that at least one of the following conditions would need to be met for TN to no longer be cost saving compared to usual care: transfer rate with usual care <12% (base-case = 82%), TN reducing the odds of transfer by <8% (base-case = 52%), or TN cost exceeding $12,989 per patient (base-case = $1,821 per patient). Conclusions: Economic modeling from the health system perspective demonstrated that TN was cost saving compared to usual care for neonates requiring consultation following delivery in a non-NICU hospital. Understanding the cost savings associated with TN may influence organizational decisions regarding implementation, diffusion, and retention of these programs.

BACKGROUND: The anti-fibrotic medications nintedanib and pirfenidone were approved in the United States for use in patients with idiopathic pulmonary fibrosis several years ago. While there is a growing body of evidence surrounding their clinical effectiveness, these medications are quite expensive and no prior cost-effectiveness analysis has been performed in the United States. METHODS: A previously published Markov model performed in the United Kingdom was replicated using United States data to project the lifetime costs and health benefits of treating idiopathic pulmonary fibrosis with: (1) symptom management; (2) pirfenidone; or (3) nintedanib. For the cost-effectiveness analysis, strategies were ranked by increasing costs and then checked for dominating treatment strategies. Then an incremental cost-effectiveness ratio was calculated for the dominant therapy. RESULTS: The anti-fibrotic medications were found to cost more than $110,000 per year compared to $12,291 annually for symptom management. While pirfenidone was slightly more expensive than nintedanib and provided the same amount of benefit, neither medication was found to be cost-effective in this U.S.-based analysis, with an average cost of $1.6 million to gain one additional quality-adjusted life year over symptom management. CONCLUSIONS: Though the anti-fibrotics remain the only effective treatment option for patients with idiopathic pulmonary fibrosis and the data surrounding their clinical effectiveness continues to grow, they are not considered cost-effective treatment strategies in the United States due to their high price.

OBJECTIVE: Despite the growing emphasis on healthcare costs, limited data address this aspect of care within the vestibular schwannoma (VS) literature. We sought to determine which strategy confers the lowest lifetime cost and greatest quality-adjusted life-years (QALYs) for patients with small- to medium-sized sporadic VS tumors. STUDY DESIGN: A Markov model was created to determine the most cost-effective management algorithm. Tumor characteristics, magnetic resonance imaging surveillance schedule, treatment outcomes, and health-related quality of life values were derived from previously published data. Cost estimates were based on CMS Fee Schedule reimbursement rates. SETTING: Economic Evaluation Service within the Kern Center for the Science of Healthcare Delivery. PATIENTS: Patients diagnosed with small- to medium-sized sporadic VS. INTERVENTIONS: Upfront microsurgery following diagnosis, upfront radiosurgery following diagnosis, observation with microsurgery reserved for observed tumor growth, and observation with radiosurgery reserved for observed tumor growth. RESULTS: Across patient ages at time of diagnosis ranging from 18 to 70âyears, observation with subsequent radiosurgery used for tumor growth was the most cost-effective management algorithm while upfront microsurgery was the least. When presented with a hypothetical 50-year-old patient, the strategy with the lowest lifetime cost and highest QALYs was observation with subsequent radiosurgery reserved for tumor growth ($32,161, 14.11 QALY), followed by observation with microsurgery reserved for tumor growth ($34,503, 13.94 QALY), upfront radiosurgery ($43,456, 14.02 QALY), and lastly, upfront microsurgery ($47,252, 13.60 QALY). Sensitivity analyses varying mortality rates, estimated costs, health-related quality of life, and progression to nonserviceable hearing demonstrated consistent ranking among treatments. CONCLUSIONS: When considering initial management of small- and medium-sized sporadic VSs, neither lifetime cost nor QALYs support upfront microsurgery or radiosurgery, even for younger patients. Initial observation with serial imaging, reserving radiosurgery or microsurgery for patients exhibiting tumor growth, confers the greatest potential for optimized lifetime healthcare cost and QALY outcomes.

INTRODUCTION: Minimally invasive tests for Barrett's esophagus (BE) detection have raised the prospect of broader nonreflux-based testing. Cost-effectiveness studies have largely studied men aged 50 years with chronic gastroesophageal reflux disease (GERD) symptoms. We evaluated the comparative cost effectiveness of BE screening tests in GERD-based and GERD-independent testing scenarios. METHODS: Markov modeling was performed in 3 scenarios in 50 years old individuals: (i) White men with chronic GERD (GERD-based); (ii) GERD-independent (all races, men and women), BE prevalence 1.6%; and (iii) GERD-independent, BE prevalence 5%. The simulation compared multiple screening strategies with no screening: sedated endoscopy (sEGD), transnasal endoscopy, swallowable esophageal cell collection devices with biomarkers, and exhaled volatile organic compounds. A hypothetical cohort of 500,000 individuals followed for 40 years using a willingness to pay threshold of $100,000 per quality-adjusted life year (QALY) was simulated. Incremental cost-effectiveness ratios (ICERs) comparing each strategy with no screening and comparing screening strategies with each other were calculated. RESULTS: In both GERD-independent scenarios, most non-sEGD BE screening tests were cost effective. Swallowable esophageal cell collection devices with biomarkers were cost effective (<$35,000/QALY) and were the optimal screening tests in all scenarios. Exhaled volatile organic compounds had the highest ICERs in all scenarios. ICERs were low (<$25,000/QALY) for all tests in the GERD-based scenario, and all non-sEGD tests dominated no screening. ICERs were sensitive to BE prevalence and test costs. DISCUSSION: Minimally invasive nonendoscopic tests may make GERD-independent BE screening cost effective. Participation rates for these strategies need to be studied.

OBJECTIVE: To estimate the cost-effectiveness of multitarget stool DNA testing (MT-sDNA) compared with colonoscopy and fecal immunochemical testing (FIT) for Alaska Native adults. PATIENTS AND METHODS: A Markov model was used to evaluate the 3 screening test effects over 40 years. Outcomes included colorectal cancer (CRC) incidence and mortality, costs, quality-adjusted life-years (QALYs), and incremental cost-effectiveness ratios (ICERs). The study incorporated updated evidence on screening test performance and adherence and was conducted from December 15, 2016, through November 6, 2019. RESULTS: With perfect adherence, CRC incidence was reduced by 52% (95% CI, 46% to 56%) using colonoscopy, 61% (95% CI, 57% to 64%) using annual FIT, and 66% (95% CI, 63% to 68%) using MT-sDNA. Compared with no screening, perfect adherence screening extends life by 0.15, 0.17, and 0.19 QALYs per person with colonoscopy, FIT, and MT-sDNA, respectively. Colonoscopy is the most expensive strategy: approximately $110 million more than MT-sDNA and $127 million more than FIT. With imperfect adherence (best case), MT-sDNA resulted in 0.12 QALYs per person vs 0.05 and 0.06 QALYs per person by FIT and colonoscopy, respectively. Probabilistic sensitivity analyses supported the base-case analysis. Under varied adherence scenarios, MT-sDNA either dominates or is cost-effective (ICERs, $1740-$75,868 per QALY saved) compared with FIT and colonoscopy. CONCLUSION: Each strategy reduced costs and increased QALYs compared with no screening. Screening by MT-sDNA results in the largest QALY savings.

Background: Compare the cost-effectiveness of 2 recombinant hepatitis B virus (HBV) vaccines in patients with inflammatory bowel disease (IBD). Methods: Markov models were developed for 2 IBD cohorts: (1) 40-year-old patients prior to starting IBD treatment and (2) 40-year-old patients already receiving therapy. Cohort A received full vaccination series, cohort B had primary vaccine failure and received a vaccine booster. Two vaccines were compared: adjuvanted HEPLISAV-B and nonadjuvanted Engerix-B. Clinical probabilities of acute hepatitis, chronic hepatitis, cirrhosis, fulminant hepatic failure and death, treatment costs, and effectiveness estimates were obtained from published literature. A lifetime analysis and a US payer perspective were used. Probabilistic sensitivity analyses were performed for different hypothetical scenarios. Results: Analysis of cohort A showed moderate cost-effectiveness of HEPLISAV-B ($88,114 per quality-adjusted life year). Analysis of cohort B showed increased cost-effectiveness ($35,563 per quality-adjusted life year). Changing Engerix-B to HEPLISAV-B in a hypothetical group of 100,000 patients prevented 6 and 30 cases of acute hepatitis; and 4 and 5 cases of chronic hepatitis annually for cohorts A and B, respectively. It also prevented 1 and 2 cases of cirrhosis, and 1 and 2 deaths over 20 years for each cohort. Cost-effectiveness was determined by vaccination costs, patient age, and progression rate from chronic hepatitis to cirrhosis. Conclusions: HEPLISAV-B is cost-effective over Engerix-B in patients receiving immunosuppressive therapy for IBD. Benefits increase with population aging and lower costs of vaccines. We advocate measuring levels of HBV antibodies in patients with IBD and favor adjuvanted vaccines when vaccination is needed.
RESUMO
PURPOSE: Pharmacogenomics (PGx) studies how inherited genetic variations in individuals affect drug absorption, distribution, and metabolism. PGx panel testing can potentially help improve efficiency and accuracy in individualizing therapy. This study compared the cost-effectiveness between preemptive PGx panel testing, reactive PGx panel testing and usual care (no testing) in cardiovascular disease management. METHODS: We developed a decision analytic model from the US payer's perspective for a hypothetical cohort of 10,000 patients ≥45 years old, using a short-term decision tree and long-term Markov model. The testing panel included the following gene-drug pairs: CYP2C19-clopidogrel, CYP2C9/VKORC1-warfarin, and SLCO1B1-statins with 30 test-return days. Costs were reported in 2019 US dollars and effectiveness was measured in quality-adjusted life years (QALYs). The primary outcome was incremental cost-effectiveness ratio (ICER = ΔCost/ΔQALY), assuming 3% discount rate for costs and QALYs. Scenario and probabilistic sensitivity analyses were performed to assess the impact of demographics, risk level, and follow-up timeframe. RESULTS: Preemptive testing was found to be cost-effective compared with usual care (ICER $86,227/QALY) at the willingness-to-pay threshold of $100,000/QALY while reactive testing was not (ICER $148,726/QALY). Sensitivity analyses suggested that our cost-effectiveness results were sensitive to longer follow-up, and the age group 45-64 years. CONCLUSION: Compared with usual care, preemptive PGx panel testing was cost-effective in cardiovascular disease management.

AIMS: To examine 1) the major drivers of index hospitalization and 3-year post-acute follow-up care, 2) cost for rehabilitation and homecare, and 3) indirect cost from lost productivity after acute ischemic stroke (AIS) and intracerebral hemorrhage (ICH). METHODS: Retrospective study of adults hospitalized with AIS (n = 811) and ICH (N = 145) between 2003 and 2014. Direct costs standardized to Medicare reimbursement rates were captured for hospitalization and 3-year follow-up or death. Adjusted cost estimates were assessed using generalized linear modeling with gamma distribution. Costs for rehabilitation, home healthcare, and lost productivity were assessed using sets of cost captured through literature review. RESULTS: Calculated as mean cost per person: hospitalization $18,154 for AIS and $24,077 for ICH; monthly 3-year aggregate $5138 for AIS and $8172 for ICH; 3-year inpatient rehabilitation $4185 for AIS and $4196 for ICH; homecare $19,728 for AIS and $14,487 for ICH; indirect cost from lost productivity $77,078 for AIS and $56,601 for ICH. Age < 55 years, being non-white, and stroke severity were strongly associated with greater hospitalization cost for AIS and ICH. Hyperlipidemia incurred lower while cancer, coronary artery disease, asthma/chronic obstructive pulmonary disease, heart failure, and anemia incurred higher 3-year aggregate cost for AIS. Cancer and diabetes mellitus incurred higher 3-year aggregate cost for ICH. CONCLUSIONS: We provide estimates of direct and indirect costs incurred for acute and continuing post-acute care through a 3-year follow-up period after first-ever AIS and ICH with important comparisons for predictors between index hospitalization and 3-year post-stroke costs.

PURPOSE: To evaluate the impact of a collaborative intervention by pharmacists and primary care clinicians on total cost of care, including costs of inpatient readmissions, emergency department visits, and outpatient care, at 30, 60, and 180 days after hospital discharge in a population of patients at high risk for readmission due to polypharmacy. METHODS: A retrospective study of cost outcomes in a cohort of adult patients discharged from a single institution from July 1, 2013 to March 25, 2016, was conducted. All patients had at least 10 medications listed on their discharge list, including at least 1 drug frequently associated with adverse events leading to hospital readmission. About half of the cohort (n = 496) attended a postdischarge visit involving both a pharmacist and a primary care clinician (a physician, physician assistant, or licensed nurse practitioner); this was designated the pharmacist/clinician collaborative (PCC) group. The remainder of the cohort (n = 500) attended a visit without pharmacist involvement; this was designated as the usual care (UC) group. Costs were compared using a quantile regression to assess the potential heterogeneous impacts of the PCC intervention across different parts of the cost distribution. All outcomes were adjusted for differences in baseline characteristics. RESULTS: At 30 days post index discharge, there was a significant decrease in total costs in the 10th and 90th cost quantiles in the PCC cohort vs the UC cohort, without a statistically significant decrease in the 25th, 50th or 75th quantiles. The difference was significant in the 75th and 90th quantiles at 60 days and in the 25th, 50th, and 75th quantiles at 180 days. There was a nonsignificant cost reduction in all other quantiles. CONCLUSION: Medically complex patients had a significantly lower total cost of care in approximately half of the adjusted cost quantiles at 30, 60, and 180 days after hospital discharge when they had a PCC visit. PCC visits can improve patient clinical outcomes while improving cost metrics.
