A danish healthcare-focused economic evaluation of first-line cryoballoon ablation versus antiarrhythmic drug therapy for the treatment of paroxysmal atrial fibrillation.

INTRODUCTION: Three randomised controlled trials (RCTs) have demonstrated that first-line cryoballoon pulmonary vein isolation decreases atrial tachycardia in patients with symptomatic paroxysmal atrial fibrillation (PAF) compared with antiarrhythmic drugs (AADs). The aim of this study was to develop a cost-effectiveness model (CEM) for first-line cryoablation compared with first-line AADs for the treatment of PAF. The model used a Danish healthcare perspective. METHODS: Individual patient-level data from the Cryo-FIRST, STOP AF and EARLY-AF RCTs were used to parameterise the CEM. The model structure consisted of a hybrid decision tree (one-year time horizon) and a Markov model (40-year time horizon, with a three-month cycle length). Health-related quality of life was expressed in quality-adjusted life years (QALYs). Costs and benefits were discounted at 3% per year. Model outcomes were produced using probabilistic sensitivity analysis. RESULTS: First-line cryoablation is dominant, meaning it results in lower costs (-€2,663) and more QALYs (0.18) when compared to first-line AADs. First-line cryoablation also has a 99.96% probability of being cost-effective, at a cost-effectiveness threshold of €23,200 per QALY gained. Regardless of initial treatment, patients were expected to receive ∼ 1.2 ablation procedures over a lifetime horizon. CONCLUSION: First-line cryoablation is both more effective and less costly (i.e. dominant), when compared with AADs for patients with symptomatic PAF in a Danish healthcare system.

Comprehensive analysis of same day discharge after atrial fibrillation ablation: Clinical, cost, and patient reported outcomes.

BACKGROUND: Same day discharge (SDD) following atrial fibrillation (AF) ablation procedure has emerged as routine practice, and primarily driven by operator discretion. However, the impacts of SDD on clinical outcomes, healthcare system costs, and patient reported outcomes (PROs) have not been systematically studied. METHODS: We retrospectively analyzed patients undergoing routine AF ablation procedures with SDD versus overnight observation (NSDD). After propensity adjustment we compared postprocedure adverse events (AEs), healthcare system costs, and changes in PROs. RESULTS: We identified 310 cases, with 159 undergoing SDD and 151 staying at least one midnight in the hospital (NSDD). Compared with NSDD, SDD patients were similar age (mean 64 vs. 66, p = 0.3), sex (26% female vs. 27%, p = 0.8), and with lower mean CHADS2-VA2Sc scores (2.0 vs. 2.7; p < 0.011). The primary outcome of AEs was noninferior in SDD versus NSDD patients (odds ratio 0.45, 95% confidence interval 0.21-0.99; noninferiority margin of 10%). There were also no differences in overall cost to the healthcare system between SDD and NSDD (p = 0.11). PROs numerically favored SDD (p = NS for all scores). CONCLUSIONS: Physician selection for SDD appears at least as safe as NSDD with respect to clinical outcomes and SDD is not significantly less costly to the health system. There is a trend towards more favorable, general PROs among SDD patients. Routine SDD should be strongly considered for patients undergoing routine AF ablation procedures.

A cost-consequence analysis comparing three cardiac ablation strategies for the treatment of paroxysmal atrial fibrillation.

BACKGROUND AND AIMS: Cardiac ablation is a well-established method for treating atrial fibrillation (AF). Pulsed field ablation (PFA) is a non-thermal therapeutic alternative to radiofrequency ablation (RFA) and cryoballoon ablation (CRYO). PFA uses high-voltage electric pulses to target cells. The present analysis aims to quantify the costs, outcomes, and resources associated with these three ablation strategies for paroxysmal AF. METHODS: Real-world clinical data were prospectively collected during index hospitalization by three European medical centers (Belgium, Germany, the Netherlands) specialized in cardiac ablation. These data included procedure times (pre-procedural, skin-to-skin and post-procedural), resource use, and staff burden. Data regarding complications associated with each of the three treatment options and redo procedures were extracted from the literature. Costs were collected from hospital economic formularies and published cost databases. A cost-consequence model from the hospital perspective was built to estimate the impact of the three treatment options in terms of effectiveness and costs. RESULTS: Across the three centers, N = 91 patients were included over a period of 12 months. A significant difference was seen in pre-procedural time (mean ± SD, PFA: 13.6 ± 3.7 min, CRYO: 18.8 ± 6.6 min, RFA: 20.4 ± 6.4 min; p < .001). Procedural time (skin-to-skin) was also different across alternatives (PFA: 50.9 ± 22.4 min, CRYO: 74.5 ± 24.5 min, RFA: 140.2 ± 82.4 min; p < .0001). The model reported an overall cost of €216,535 per 100 patients treated with PFA, €301,510 per 100 patients treated with CRYO and €346,594 per 100 patients treated with RFA. Overall, the cumulative savings associated with PFA (excluding kit costs) were €850 and €1,301 per patient compared to CRYO and RFA, respectively. CONCLUSION: PFA demonstrated shorter procedure time compared to CRYO and RFA. Model estimates indicate that these time savings result in cost savings for hospitals and reduce outlay on redo procedures. Clinical practice in individual hospitals varies and may impact the ability to transfer the results of this analysis to other settings.

Cost-Effectiveness and Budget Impact Analysis of Apixaban and Rivaroxaban Versus Warfarin in the Prevention of Stroke in Patients With Non-Valvular Atrial Fibrillation (NVAF) in Iran.

INTRODUCTION: This study evaluates the cost-effectiveness of Apixaban and Rivaroxaban, compared to Warfarin, for stroke prevention in patients with non-valvular atrial fibrillation in Iran. METHOD: A Markov model with a 30-year time horizon was employed to simulate and assess different treatment strategies' cost-effectiveness. The study population comprised Iranian adults with NVAF, identified through specialist consultations, hospital visits, and archival record reviews. Direct medical costs, direct nonmedical, and indirect costs were included. Quality-adjusted life years (QALY) were assessed using an EQ-5D questionnaire. This study utilized a cost-effectiveness threshold of $11 134 per QALY. RESULTS: Apixaban demonstrated superior cost-effectiveness compared to Rivaroxaban and Warfarin. Over 30 years, total costs were lower in the Apixaban and Rivaroxaban groups compared to the Warfarin group ($126.18 and $109.99 vs. $150.49). However, Apixaban showed higher total QALYs gained compared to others (0.134 vs. 0.133 and 0.116). The incremental cost-effectiveness ratio for comparing Apixaban to Warfarin was calculated at -1332.83 cost per QALY, below the threshold of $11 134, indicating Apixaban's cost-effectiveness. Sensitivity analyses confirmed the robustness of the findings, with ICER consistently remaining below the threshold. Over 5 years (2024-2028) of Apixaban usage, the incremental cost starts at USD 70 250 296 in the first year and gradually rises to USD 71 770 662 in the fifth year. DSA and PSA were assessed to prove the robustness of the results. CONCLUSION: This study shows that Apixaban is a cost-effective option for stroke prevention in non-valvular atrial fibrillation patients in Iran compared to Warfarin.

Association Between Sleep Apnea Treatment and Health Care Resource Use in Patients With Atrial Fibrillation.

BACKGROUND: Obstructive sleep apnea (OSA) contributes to the generation, recurrence, and perpetuation of atrial fibrillation, and it is associated with worse outcomes. Little is known about the economic impact of OSA therapy in atrial fibrillation. This retrospective cohort study assessed the impact of positive airway pressure (PAP) therapy adherence on health care resource use and costs in patients with OSA and atrial fibrillation. METHODS AND RESULTS: Insurance claims data for ≥1 year before sleep testing and 2 years after device setup were linked with objective PAP therapy use data. PAP adherence was defined from an extension of the US Medicare 90-day definition. Inverse probability of treatment weighting was used to create covariate-balanced PAP adherence groups to mitigate confounding. Of 5867 patients (32% women; mean age, 62.7 years), 41% were adherent, 38% were intermediate, and 21% were nonadherent. Mean±SD number of all-cause emergency department visits (0.61±1.21 versus 0.77±1.55 [P=0.023] versus 0.95±1.90 [P<0.001]), all-cause hospitalizations (0.19±0.69 versus 0.24±0.72 [P=0.002] versus 0.34±1.16 [P<0.001]), and cardiac-related hospitalizations (0.06±0.26 versus 0.09±0.41 [P=0.023] versus 0.10±0.44 [P=0.004]) were significantly lower in adherent versus intermediate and nonadherent patients, as were all-cause inpatient costs ($2200±$8054 versus $3274±$12 065 [P=0.002] versus $4483±$16 499 [P<0.001]). All-cause emergency department costs were significantly lower in adherent and intermediate versus nonadherent patients ($499±$1229 and $563±$1292 versus $691±$1652 [P<0.001 and P=0.002], respectively). CONCLUSIONS: These data suggest clinical and economic benefits of PAP therapy in patients with concomitant OSA and atrial fibrillation. This supports the value of diagnosing and managing OSA and highlights the need for strategies to enhance PAP adherence in this population.

Cost-effectiveness of left atrial appendage occlusion during cardiac surgery in France: An economic evaluation based on the LAAOS III study.

OBJECTIVES: Left atrial appendage occlusion during cardiac surgery is a therapeutic option for stroke prevention in patients with atrial fibrillation. The effectiveness and safety of left atrial appendage occlusion have been evaluated in several studies, including the LAAOS-III trial. While these studies have demonstrated efficacy and safety, the long-term economic impact of this surgical technique has not yet been assessed. Here, we aimed to evaluate the cost-effectiveness and cost-utility of left atrial appendage occlusion during cardiac surgery over a long-term time horizon. METHODS: Our study was based on a model representing an hypothetical cohort with the same characteristics as LAAOS-III trial patients. We modelled the incidence of ischemic strokes and systemic embolisms in each intervention arm: "occlusion" and "no-occlusion," using a one-month cycle length with a 20-year time horizon. Regarding occlusion devices, sutures, staples, or an approved surgical occlusion device (AtriClip™-AtriCure, Ohio, USA) could be used. RESULTS: Our model generated an average cost savings of 607 euros per patient and an incremental gain of 0.062 quality-adjusted life years (QALYs), resulting an incremental cost-utility ratio (ICUR) of €-9,775/QALY. The scenario analysis in which occlusion was systematically performed using the AtriClip™ device generated an ICUR of €3,952/QALY gained. CONCLUSIONS: In the base-case analysis, the strategy proved to be more effective and less costly, confirming left atrial appendage occlusion during cardiac surgery as an economically dominant strategy. The scenario analysis also appeared cost-effective, although it did not result in cost savings. This study provides a new perspective on the assessment of the cost-effectiveness of these techniques.

Pulsed field ablation with the pentaspline catheter compared with cryoablation for the treatment of paroxysmal atrial fibrillation in the UK NHS: a cost-comparison analysis.

OBJECTIVES: Pulsed field ablation (PFA) is a promising new ablation modality for the treatment of atrial fibrillation (AF) that has recently become available in the UK National Health Service (NHS). We provide the first known economic evaluation of the technology. METHODS: A cost-comparison model was developed to compare the expected 12-month costs of treating AF using the pentaspline PFA catheter compared with cryoablation for a single hypothetical patient. Model parameters were based on a recent cost-effectiveness analysis by the National Institute for Health and Care Excellence where possible or published literature otherwise. Deterministic sensitivity, scenario and threshold analyses were conducted. RESULTS: Costs for a single patient treated with PFA were -3% (-£343) less over 12 months than those who received treatment with cryoablation. PFA was associated with 16% higher catheter costs but repeat ablation costs were over 50% less, driven by a reduction in repeat ablations required. Costs of managing complications were -£211 less in total for PFA compared with cryoablation. CONCLUSIONS: Routine adoption of PFA with the pentaspline PFA catheter looks to be as affordable for the NHS as current treatment alternative cryoablation.

Prevalence, trends, and outcomes of atrial fibrillation in hospitalized patients with metastatic cancer: findings from a national sample.

BACKGROUND: Epidemiological evidence regarding the link between cancer and atrial fibrillation (AF) are limited and outcomes of metastatic cancer comorbid with AF need to be elucidated. OBJECTIVE: This study aims to evaluate the prevalence, temporal trends, and outcomes of AF in hospitalized metastatic cancer patients. METHODS: The National Inpatient Sample (NIS) database was used to identify adult patients with metastatic tumors from 2003 to 2014. We analyzed the trends in AF prevalence, in-hospital mortality, total cost, length of stay (LOS), and comorbidities pertaining to metastatic cancer. Multivariable-adjusted models were used to evaluate the association of AF with clinical factors, in-hospital mortality, total cost, and LOS. RESULTS: Among 2,478,598 patients with metastatic cancer, 8.74% (216,737) were diagnosed with AF. The proportion of comorbid AF increased from 8.28% in 2003 to 10.06% in 2014 (p < 0.0001). Older age, white race, male, Medicare, higher income, larger hospital bed size, and urban teaching hospital were associated with higher AF occurrence. Among primary tumor sites, lung cancer experienced the highest odds of AF compared to other cancers. Patients with metastasis to lymph node and respiratory organ had higher odds of AF. In metastatic cancer, AF was associated with higher in-hospital mortality (odds ratio: 1.48; 95% confidence interval: 1.43-1.54), 18% longer LOS, and 19% higher cost. CONCLUSIONS: AF prevalence in metastatic cancer continues to increase from 2003 to 2014. AF is linked to poorer prognosis and higher healthcare resource utilization. As the population ages, optimal preventive and treatment management strategies are needed for metastatic cancer comorbid with AF.

Is Screening for Atrial Fibrillation and Its Risk Factors Useful and Cost-Effective?

Atrial fibrillation (AF) is a major, preventable cause of stroke, whose prevalence is increasing with the aging of the population. There are safe and effective anticoagulation therapies to prevent stroke and new technologies that can identify AF in asymptomatic individuals. Ongoing research will determine if AF screening is cost-effective and will define the best screening strategies. The effectiveness of AF screening can be enhanced by simultaneously screening for the cardiovascular conditions that predispose to the development and progression of AF and its complications. Future studies evaluating an integrated screening program on outcomes, health care utilization, and cost are needed.

Atrial Fibrillation Screen, Management, and Guideline-Recommended Therapy in the Rural Primary Care Setting: A Cross-Sectional Study and Cost-Effectiveness Analysis of eHealth Tools to Support All Stages of Screening.

BACKGROUND Internationally, most atrial fibrillation (AF) management guidelines recommend opportunistic screening for AF in people ≥65 years of age and oral anticoagulant treatment for those at high stroke risk (CHA2DS2-VA≥2). However, gaps remain in screening and treatment. METHODS AND RESULTS General practitioners/nurses at practices in rural Australia (n=8) screened eligible patients (≥65 years of age without AF) using a smartphone ECG during practice visits. eHealth tools included electronic prompts, guideline-based electronic decision support, and regular data reports. Clinical audit tools extracted de-identified data. Results were compared with an earlier study in metropolitan practices (n=8) and nonrandomized control practices (n=69). Cost-effectiveness analysis compared population-based screening with no screening and included screening, treatment, and hospitalization costs for stroke and serious bleeding events. Patients (n=3103, 34%) were screened (mean age, 75.1±6.8 years; 47% men) and 36 (1.2%) new AF cases were confirmed (mean age, 77.0 years; 64% men; mean CHA2DS2-VA, 3.2). Oral anticoagulant treatment rates for patients with CHA2DS2-VA≥2 were 82% (screen detected) versus 74% (preexisting AF)(P=NS), similar to metropolitan and nonrandomized control practices. The incremental cost-effectiveness ratio for population-based screening was AU$16 578 per quality-adjusted life year gained and AU$84 383 per stroke prevented compared with no screening. National implementation would prevent 147 strokes per year. Increasing the proportion screened to 75% would prevent 177 additional strokes per year. CONCLUSIONS An AF screening program in rural practices, supported by eHealth tools, screened 34% of eligible patients and was cost-effective. Oral anticoagulant treatment rates were relatively high at baseline, trending upward during the study. Increasing the proportion screened would prevent many more strokes with minimal incremental cost-effectiveness ratio change. eHealth tools, including data reports, may be a valuable addition to future programs.

Comparison of Anticoagulants for Postoperative Atrial Fibrillation After Coronary Artery Bypass Grafting: A Pilot Study.

BACKGROUND: Direct-acting oral anticoagulants are indicated for the treatment of nonvalvular atrial fibrillation, but their use in patients after undergoing cardiac surgery is poorly defined despite a high prevalence of postoperative atrial fibrillation in this population. METHODS: Patients diagnosed with postoperative atrial fibrillation were prospectively randomized to warfarin or apixaban. Safety, efficacy, and economic outcomes were evaluated until their 4- to 6-week postoperative appointment. RESULTS: While this pilot study was not powered to determine a difference in safety or efficacy, adverse event rates were similar to the published literature. It was noted that a patient's course of therapy when utilizing apixaban was significantly less costly than warfarin when including medication, bridging, and laboratory expenses. CONCLUSION: Apixaban and warfarin both appeared to be safe and effective for anticoagulation throughout the duration of this pilot study in treating postoperative atrial fibrillation after coronary artery bypass grafting. Apixaban was associated with significantly less expense when bridging and monitoring costs were included in addition to medication expense.

Budget impacts associated with improving diagnosis and treatment of atrial fibrillation in high-risk stroke patients.

Aim: Estimate the 3-year budget impact in England from 2016/17 of improving nonvalvular atrial fibrillation management in high-risk stroke patients. Materials & methods: The Academic Health Science Network's AF Business Case Model was used to identify detection, protection (risk assessment and treatment initiation) and perfection (optimized treatment) gaps and to project the budget impact of closing these. Results: Closing all gaps over 3 years could prevent 27,550 strokes. Overall, perfection gap savings were £136,650,962 and protection gap savings were £58,146,171. Detection by screening in year one could cost £149,048,676, but with stroke-prevention savings would be £47,081,047 at 3 years. Thus, total potential savings were £194,797,133 and the cost-adjusted budget impact was £147,716,086. Conclusion: The detection and perfection gaps are key areas for investment.

Budget Impact of Cryoablation Versus Radiofrequency Ablation of Atrial Fibrillation in the Brazilian Public Healthcare System.

BACKGROUND: Cryoablation is a new technology for ablation of atrial fibrillation (AF), effective and safe when compared with standard radiofrequency (RF) ablation. Nevertheless, the economic impact of its incorporation is unknown, especially considering the public health system of a developing country. This study analyzed the budget impact of cryoablation incorporation for treatment of paroxysmal AF in the Brazilian public health system. METHODS: The budget impact was calculated as the cost difference between the current scenario (RF ablation guided by electroanatomic mapping) and the new scenario (cryoablation). The cost of each intervention was obtained by multiplying the price of a single procedure by the number of candidates for it. Other technologies (RF ablation guided by intracardiac echocardiography or with a nonirrigated catheter) were considered in a sensitivity analysis. RESULTS: The budget impact showed savings of $43 097 096.84 with cryoablation. In the sensitivity analysis, cryoablation resulted in cost savings compared with RF ablation guided by intracardiac echocardiography, whereas in comparison to RF ablation with the nonirrigated catheter, cryoablation was more expensive. A market share assessment, performed using an incorporation rate of 3% per year, indicated savings of approximately $800 000 per 5 years. CONCLUSIONS: Cryoablation of AF resulted in cost savings compared with the current scenario (RF ablation guided by electroanatomic mapping). When alternative technologies were considered, cryoablation was more expensive than RF ablation with a nonirrigated catheter, but it also resulted in savings compared with RF ablation guided by intracardiac echocardiography. Overall, cryoablation of AF may reduce expenditures in the Brazilian public health system.

Healthcare Utilization and Costs Reduction after Radiofrequency Ablation For Atrial Fibrillation in the Brazilian Private Healthcare System / Redução na Utilização de Recursos em Saúde e dos Custos após Ablação por Radiofrequência da Fibrilação Arial na Saúde Suplementar Brasileira

Abstract Background: Atrial fibrillation (AF) is the most common arrhythmia worldwide, with significantly associated hospitalizations. Considering its growing incidence, the AF related economic burden to healthcare systems is increasing. Healthcare expenditures might be substantially reduced after AF radiofrequency ablation (AFRA). Objective: To compare resource utilization and costs before and after AFRA in a cohort of patients from the Brazilian private healthcare system. Methods: We conducted a retrospective cohort study, based on patients' billing information from an administrative database. Eighty-three adult patients who had an AFRA procedure between 2014 and 2015 were included. Healthcare resource utilization related to cardiovascular causes, including ambulatory and hospital care, as well as its costs, were analyzed. A p-value of less than 0.05 was considered statistically significant. Results: Mean follow-up was 14.7 ± 7.1 and 10.7 ± 5.4 months before and after AFRA, respectively. The 1-year AF recurrence-free rate was 83.6%. Before AFRA, median monthly total costs were Brazilian Reais (BRL) 286 (interquartile range [IQR]: 137-766), which decreased by 63.5% (p = 0.001) after the procedure, to BRL 104 (IQR: 57-232). Costs were reduced both in the emergency (by 58.6%, p < 0.001) and outpatient settings (by 56%, p < 0.001); there were no significant differences in the outpatient visits, inpatient elective admissions and elective admission costs before and after AFRA. The monthly median emergency department visits were reduced (p < 0.001). Conclusion: In this cohort, overall healthcare costs were reduced by 63.5%. A longer follow-up could be useful to evaluate if long-term cost reduction is maintained.

Resumo Fundamento: A fibrilação atrial (FA) é a arritmia mais comum em todo o mundo, com hospitalizações significativamente associadas. Considerando sua crescente incidência, a carga econômica relacionada à FA para os sistemas de saúde está aumentando. Os gastos com saúde podem ser substancialmente reduzidos após a ablação por radiofrequência (ARF). Objetivo: Comparar a utilização de recursos e os custos anteriores e posteriores à ARF em uma coorte de pacientes do sistema de saúde privado brasileiro. Métodos: Foi realizado um estudo de coorte retrospectivo, com base nas informações de cobrança dos pacientes de um banco de dados administrativo. Foram incluídos oitenta e três pacientes adultos que passaram pelo procedimento de ARF entre 2014 e 2015. A utilização de recursos de saúde relacionados às causas cardiovasculares, incluindo atendimento ambulatorial e hospitalar, assim como seus custos, foram analisados. Um valor de p inferior a 0,05 foi considerado estatisticamente significativo. Resultados: O seguimento médio foi de 14,7 ± 7,1 e 10,7 ± 5,4 meses antes e após a ARF, respectivamente. A taxa de FA livre de recidiva em 1 ano foi de 83,6%. Antes da ARF, a mediana dos custos totais mensais foi de R$286,00 (intervalo interquartil [IIQ]: 137-766), com redução de 63,5% (p = 0,001) após o procedimento, para um valor de R$104 (IIQ: 57-232). Os custos foram reduzidos tanto na emergência (em 58,6%, p < 0,001) como no ambiente ambulatorial (em 56%, p < 0,001); não houve diferenças significativas nas consultas ambulatoriais, internações eletivas e custos de internação eletiva antes e depois da ARF. As medianas das consultas mensais no setor de emergência foram reduzidas (p < 0,001). Conclusão: Nesta coorte, os custos gerais com saúde foram reduzidos em 63,5%. Um seguimento mais longo pode ser útil para avaliar se a redução de custos em longo prazo é mantida.

Cost-effectiveness and screening performance of ECG handheld machine in a population screening programme: The Belgian Heart Rhythm Week screening programme.

AIMS: Overall, 40% of patients with atrial fibrillation are asymptomatic. The usefulness and cost-effectiveness of atrial fibrillation screening programmes are debated. We evaluated whether an atrial fibrillation screening programme with a handheld electrocardiogram (ECG) machine in a population-wide cohort has a high screening yield and is cost-effective. METHODS: We used a Markov-model based modelling analysis on 1000 hypothetical individuals who matched the Belgian Heart Rhythm Week screening programme. Subgroup analyses of subjects ≥65 and ≥75 years old were performed. Screening was performed with one-lead ECG handheld machine Omron® HeartScan HCG-801. RESULTS: In both overall population and subgroups, the use of the screening procedure diagnosed a consistently higher number of diagnosed atrial fibrillation than not screening. In the base-case scenario, the screening procedure resulted in 106.6 more atrial fibrillation patient-years, resulting in three fewer strokes, 10 more life years and five more quality-adjusted life years (QALYs). The number needed-to-screen (NNS) to avoid one stroke was 361. In subjects ≥65 years old, we found 80.8 more atrial fibrillation patient-years, resulting in three fewer strokes, four more life-years and five more QALYs. The NNS to avoid one stroke was 354. Similar results were obtained in subjects ≥75 years old, with a NNS to avoid one stroke of 371. In the overall population, the incremental cost-effectiveness ratio for any gained QALY showed that the screening procedure was cost-effective in all groups. CONCLUSIONS: In a population-wide screening cohort, the use of a handheld ECG machine to identify subjects with newly diagnosed atrial fibrillation was cost-effective in the general population, as well as in subjects ≥65 and subjects ≥75 years old.

Postoperative atrial fibrillation: evaluation of its economic impact on the costs of cardiac surgery

Abstract Objective: The objective of this study was to calculate the direct costs of postoperative atrial fibrillation (POAF) in a high-complexity cardiovascular hospital. Methods: We performed a cost analysis with a pairwise-matched design. Twenty-two patients with POAF and 22 patients without this complication were included. Pair-matching was performed (1:1) based on the following criteria: identical type of surgery, similar EuroSCORE II values, and absence of any other postoperative complication. Results: The total hospital cost was significantly higher in the POAF group than in the non-POAF group (US$ 10,880 [± 2,688] vs. US$ 8,856 [± 1,782], respectively, for each patient; P=0.005). This difference was attributable to postoperative costs (US$ 3,103 [± 1,552] vs. US$ 1,238 [± 429]; P=0.0001) for patients with or without POAF, respectively. The median postoperative lengths of stay were 9 (range 5-17) and 5 (3-9) days for patients with and without POAF (P=0.032), respectively. Preoperatively, no differences were found in the EuroSCORE II values (median 1.7 vs. 1.6, respectively; P=0.91) or direct costs (US$ 1,127 vs. US$ 1,063, respectively; P=0.56) between POAF and non-POAF groups. Conclusion: POAF generates a high economic burden in the overall costs of cardiac surgery, and our results reveal the differential contribution of each of the evaluated factors. This information, which was previously unavailable in this setting, is essential for the development of more effective prevention strategies.

Inguinal vascular complications after ablation of atrial fibrillation: an economic impact assessment.

AIMS: Ablation of atrial fibrillation (AF) is recommended in the guidelines as a Class Ia/IIa indication. However, associated complications should not be dismissed; specifically, inguinal vascular complications (IVC). Although IVCs are generally considered trivial, they represent an economic burden for the procedure-performing hospital and the patient. Therefore, the ability to monitor and ultimately minimize potential complications is of considerable interest. METHODS AND RESULTS: An economic model was developed to calculate the economic impact for certain IVC-types from a large German single-centre perspective in 2015 and 2016. Twenty-nine of 1040 (2.79%) and 48 of 1152 (4.17%) AF-ablation patients had documented IVC in 2015 and 2016 (P = 0.08), respectively. Inguinal vascular complications that required invasive treatment (thrombin, intervention, surgery) occurred in 0.58% of the 2015 and in 0.87% of the 2016 AF-ablation cases. The expected excess costs (incorporating direct costs, benefit lost adjusted for reimbursement) per patient treated with AF-ablation were 139.54€ and 153.31€ in 2015 and 2016, respectively. This was mostly driven by opportunity costs, which could reach 15 544.71€ for certain IVC. Sensitivity analysis revealed the probability of occurrence, length of stay of certain IVC types, and the revenue per day influenced the expected costs per AF-ablation patient. CONCLUSION: Even relatively benign complications such as IVC can result in considerable cost increases. Therefore, measures to reduce them should be established and implemented.

Postoperative complications decrease the cost-effectiveness of robotic-assisted lobectomy.

BACKGROUND: Cost of robotic-assisted (RATS) lobectomy remains a major concern. We sought to define variability in cost and factors associated with increased hospital expenses after RATS lobectomy for early stage non-small cell lung cancer. METHODS: We performed a retrospective review of patients who underwent RATS lobectomy for stages I-IIIA non-small cell lung cancer at a single institution between 2012 and 2014. Clinical outcomes were linked to hospital financial data. Linear regression analysis was used to test the impact of patient factors and postoperative outcomes on cost. RESULTS: A total of 137 patients underwent RATS lobectomy, predominantly for stage IA (73%, n = 100). Overall in-hospital morbidity was 29.2% (n = 40), median length of stay was 5 days (range 1-27 days). Postoperative cost accounted for approximately 50% of total cost of hospitalization and varied significantly (mean $9,618.38 ± $10,779.65), resulting in an average total hospital cost of $19,565 (±$11,620.42). Male sex and upper lobe predominant disease were independently associated with increased cost, whereas higher preoperative diffusing capacity of lung for carbon monoxide (DLCO) was cost-protective. Hospital expenses associated with prolonged hospitalization were $2,376.23 per day (95% CI $2,178-2,573.60). The most common complication associated with increased cost was atrial fibrillation ($5,609.13; 95% CI $2,095.42-$9,122.84). Postoperative atelectasis requiring bronchoscopy, respiratory failure, pulmonary embolism, and reoperation were seen less frequently in this cohort of patients but were associated with significant additional cost. CONCLUSION: Hospital cost of RATS lobectomy can vary significantly. In addition to patient risk factors, differences in cost are mainly driven by postoperative events. Initiatives aimed to reduce common yet expensive complications have the potential to improve overall cost-effectiveness of RATS lobectomy.

Economic impact of atrial fibrillation ablation with radiofrequency contact force catheter versus cryoballoon catheter.

AIM: To compare health utilization among atrial fibrillation (AF) patients undergoing ablation with a contact force-sensing (CF) catheter versus a cryoballoon (CB) catheter. METHODS: AF patients who underwent ablation using the CF catheter (THERMOCOOL SMARTTOUCH® catheter) or CB catheter (Arctic Front™/Arctic Front Advance™ catheter) were identified from the Premier Healthcare database. Propensity score analyses were used to evaluate cost, length of stay and readmissions. RESULTS: The CF catheter (n = 1409) was associated with significantly lower total (∼7%) and supply (∼13%) costs and a significantly lower likelihood of 4-12 month all-cause and CV-related readmission compared with the CB catheter (n = 2306). CONCLUSION: Differential health utilization outcomes are associated with the CF catheter versus the CB catheter in AF ablation.
