RESUMO

Transesophageal echocardiography (TEE) under general anesthesia (GA) or intracardiac echocardiography (ICE) under sedation is usually used for echocardiographic guidance during transcatheter atrial septal defect (ASD) closure. However, appropriate selection of guidance has not been fully established. Our study aimed to evaluate whether selection of guidance depending on anatomic ASD features and TEE tolerability under sedation contributes to procedure success. On the basis of anatomic ASD characteristics and TEE tolerability under sedation during the pre-procedural TEE, we selected either TEE, ICE, or combined TEE and ICE under moderate-to-deep sedation or TEE under GA for guidance. Anatomic characteristics of the defect, medical costs, complications, and primary outcomes for these four different types of guidance were analyzed. A total of 154 patients were classified into four guidance groups depending on the results of diagnostic TEE under sedation; 11 patients were scheduled for the procedure under GA in advance. Procedures were successfully completed in all but two patients in whom closure guided by TEE under sedation was attempted for an extremely large defect or extensive superior rim deficiency. Two patients who underwent TEE or combined TEE and ICE guidance under sedation were converted to ICE-only guidance due to desaturation or excessive body movement. Device dislodgement was not observed during the procedure or during median follow-up of 1188 days [interquartile range 577-1831]. Appropriate selection of guidance might contribute to successful transcatheter ASD closure.

RESUMO

Low work participation is well known in patients with chronic disease but has not been described in patients with atrial septal defect (ASD). In this nation-wide cohort study, we report the first long-term follow-up of use of permanent social security benefits and work participation in adults with ASD. All Danes born before 1994 and diagnosed with ASD from 1959 to 2013 (n = 2,277) were identified from the Danish medical registries. We used Cox proportional hazards regression to compare the risk of receiving permanent social security benefits in the ASD patients compared with an age- and gender-matched general population cohort. Using the DREAM database, we calculated work participation score and proportion of patients working or not working at the age of 30 years. Median follow-up from ASD diagnosis was 23.4 years (range 0.2 to 59.3). ASD patients had a higher risk of receiving permanent social security benefits (hazard ratio 2.3 [95% confidence interval 2.1 to 2.6]) compared with the comparison cohort with 24% of the ASD patients receiving permanent social security benefits at the end of follow-up compared with 12% of the comparison cohort. At the age of 30 years, the proportion not working was 28% in the ASD cohort and 18% in the comparison cohort. In patients with ASD, 23% of those without a job had a psychiatric diagnosis. In conclusion, the risk of receiving permanent social security benefits was twice as high in patients with ASD and the work participation score was reduced compared with the background population.

RESUMO

Atrial septal defects (ASD) are among the most common congenital heart defects. As more ASDs are corrected by interventional catheterization instead of surgery, it is critical to understand the associated clinical and societal costs. The goal of this study was to use a national U.S. database to describe hospital charges and societal costs for surgical and catheter-based (ASD) closure. Retrospective review of hospital discharge data from the Kids' Inpatient Database from January 2010 to December 2012. The database was queried for admissions for <21 years old with ICD-9 procedure codes for surgical (35.51 or 35.61) or catheter (35.52) ASD closure; those with other cardiac conditions and/or additional cardiac procedures were excluded. Age, length of stay (LOS), and hospital charges and lost parental wages (societal costs) were compared between groups using t test or Mann-Whitney U test, as appropriate. Four hundred and eighty-six surgical and 305 catheter ASD closures were identified. LOS, hospital charges, and total societal costs were higher in surgical ASD compared to catheter ASD admissions (3.6 vs. 1.3 days, p < 0.001, $87,465 vs. $64,109, p < 0.001, and $90,000 vs. $64,966, p < 0.001, respectively). In this review of a large national inpatient database, we found that hospital and societal costs for surgical ASD closure are significantly higher than catheter ASD closure in the United States in the current era. Factors that likely contribute to this include longer LOS and longer post-operative recovery. Using "real-world" data, this study demonstrates a substantial cost advantage for catheter ASD closure compared to surgical.

RESUMO

OBJECTIVES: The purpose of this study was to determine whether a transcatheter procedure or surgical closure offers a better value proposition for atrial septal defect (ASD) closure. BACKGROUND: Secundum ASDs are common congenital heart defects with both transcatheter and surgical treatment options. Although both options have been shown to have excellent results in children, the relative value of the 2 procedures is unclear. METHODS: Using data from the Pediatric Hospital Information System for 2004 to 2012, we compared the value of transcatheter versus surgical ASD closure for children ages 1 to 17 years, with value being defined as outcomes relative to costs. Total charges for procedure-related encounters were converted to costs using hospital-specific cost-to-charge ratios, and all costs were adjusted for inflation to reflect 2012 dollars. RESULTS: There were 4,606 transcatheter procedures and 3,159 surgeries at 35 children's hospitals. Those undergoing transcatheter closure were more likely to be older (5.6 years vs. 4.5 years, p < 0.0001). There was no mortality in either group. Children with a surgical procedure had a longer length of stay (4.0 days vs. 1.5 days, p < 0.0001), were more likely to have an infection (odds ratio: 3.73, p < 0.0001) or procedural complication (odds ratio: 6.66, p < 0.0001). Costs for transcatheter procedure encounters were lower than costs for surgical encounters (mean of $19,128 vs. $25,359, p < 0.0001). CONCLUSIONS: Both transcatheter and surgical ASD closure had excellent short-term outcomes, but transcatheter procedures had lower lengths of stay, rates of infection, and complications, resulting in lower overall costs. For children who are eligible, transcatheter ASD closure provides better short-term value than surgery.

RESUMO

The aim of this study was to perform a budget impact analysis on the adoption of percutaneous occlusion of ostium secundum atrial septal defects in the Brazilian Unified National Health System. Costs were collected using micro-costing technique from medical records for each treatment technique (conventional surgery versus percutaneous septal occluder) at a public federal hospital specialized in high-complexity cardiology. The analysis showed that expenditures associated with percutaneous occlusion were lower than with conventional surgery, and sensitivity analysis confirmed the cost reduction in several scenarios, showing a significant budget impact with a 30% adoption rate for the percutaneous occluder (savings of approximately 1.5 million dollars per year). The study indicates that the adoption of the percutaneous septal occluder would mean cost savings of approximately 3.5 million dollars for the Brazilian public health system.

O objetivo foi analisar o impacto orçamentário da incorporação do oclusor septal percutâneo para o tratamento de defeitos do septo atrial do tipo ostium secundum, sob a perspectiva do Sistema Único de Saúde brasileiro. Os custos foram coletados por microcusteio com base nos registros das intervenções terapêuticas (cirurgia convencional ou implante percutâneo de oclusor septal) realizadas em um hospital público federal especializado em cardiologia de alta complexidade. A análise identificou que os custos associados ao procedimento percutâneo de oclusor septal foram inferiores aos relacionados com a cirurgia convencional, a análise de sensibilidade confirmou a redução dos custos em diversos cenários e mostrou que o impacto no orçamento foi significativo a partir de uma taxa de incorporação de 30% do oclusor septal percutâneo pelo sistema de saúde (redução dos gastos em torno de 1,5 milhão de dólares por ano). O estudo indica que a adoção do implante percutâneo do oclusor septal pode representar uma economia de aproximadamente 3,5 milhões de dólares para o sistema de saúde brasileiro.


El estudio consistió en analizar el impacto presupuestario de la implementación del oclusor septal percutáneo para el tratamiento de defectos del tabique auricular del ostium secundum, desde la perspectiva del Sistema Único de Salud. Los costes incluidos en el modelo por la técnica de micro-coste se obtuvieron de los registros de las intervenciones terapéuticas (cirurgía convencional u oclusor septal percutáneo) en un hospital público federal, especializado en cardiología de alta complejidad. El análisis reveló que los costos asociados con el oclusor septal percutáneo fueron más bajos que los asociados con la cirugía convencional, un análisis de sensibilidad confirmó la reducción de costos en diferentes escenarios y mostró que el impacto fue significativo desde una tasa del 30% de incorporación del oclusor septal percutáneo por el sistema de salud (reducción en el gasto de alrededor de 1.5 millones de dolares por año). El estudio indica que la adopción del implante percutáneo del oclusor septal puede representar un ahorro de aproximadamente 3,5 millones de dólares anuales al sistema de salud brasileño.

RESUMO

BACKGROUND: Contemporary data regarding percutaneous closure of atrial septal defect/patent foramen ovale (ASD/PFO) are lacking. We evaluated the current trends in utilization of ASD/PFO closure in adults and investigated the effect of annual hospital volume on in-hospital outcomes. METHODS: We queried the Nationwide Inpatient Sample between the years 2001 and 2010 using the International Classification of Diseases (ICD-9-CM) procedure code for percutaneous closure of ASD/PFO with device. Hierarchical mixed effects models were generated to identify the independent multivariate predictors of outcomes. RESULTS: A total of 7,107 percutaneous ASD/PFO closure procedures (weighted n = 34,992) were available for analysis. A 4.7-fold increase in the utilization of this procedure from 3/million in 2001 to 14/million adults in 2010 in US (P < 0.001) was noted. Overall, percutaneous ASD/PFO closure was associated with 0.5% mortality and 12% in-hospital complications. The utilization of intracardiac echocardiography (ICE) increased 15 fold (P < 0.001) during the study period. The procedures performed at the high volume hospitals [2nd (14-37 procedures/year) and 3rd (>38 procedures/year) tertile] were associated with significant reduction in complications, length of stay and cost of hospitalization when compared to those performed at lowest volume centers (<13 procedures/year). Majority (70.5%) of the studied hospitals were found to be performing <10 procedures/year hence deviating from the ACC/AHA/SCAI clinical competency guidelines. CONCLUSIONS: Low hospital volume is associated with an increased composite (mortality and procedural complications) adverse outcome following ASD/PFO closure. In the interest of patient safety, implementation of the current guidelines for minimum required annual hospital volume to improve clinical outcomes is warranted.

RESUMO

INTRODUCTION: Cost-effectiveness (CE) studies of percutaneous (PC) versus surgical (SC) atrial septal defect closure are lacking. METHODS: A systematic literature review in children and a CE analysis based on a model of long-term outcomes were performed. Direct costs of PC and SC were US$8700 (defined arbitrarily) and US$5700 (actually paid), respectively. Three-times the Brazilian GDI (US$28,700) per year of life saved (with a discount rate of 5%) was used as a limit for willingness-to-pay. DISCUSSION: PC had a high (US$104,500) incremental CE ratio despite lower complication rates, shorter hospital stay and better (nonsignificant) adjusted life expectancy. PC would be cost-effective if it cost US$6400 or SC had an 8% loss of utility or its indirect costs were US$2250. Costs of PC should be reduced to be cost-effective in the Brazilian public health system. Indirect costs and impact on quality of life should be further assessed.

RESUMO

OBJECTIVES: The study performs a cost-effectiveness analysis of procedures for atrial septal defects occlusion, comparing conventional surgery to septal percutaneous implant. METHODS: A model of analytical decision was structured with symmetric branches to estimate cost-effectiveness ratio between the procedures. The decision tree model was based on evidences gathered through meta-analysis of literature, and validated by a panel of specialists. The lower number of surgical procedures performed for atrial septal defects occlusion at each branch was considered as the effectiveness outcome. Direct medical costs and probabilities for each event were inserted in the model using data available from Brazilian public sector database system and information extracted from the literature review, using micro-costing technique. Sensitivity analysis included price variations of percutaneous implant. RESULTS: The results obtained from the decision model demonstrated that the percutaneous implant was more cost effective in cost-effectiveness analysis at a cost of US$8,936.34 with a reduction in the probability of surgery occurrence in 93% of the cases. Probability of atrial septal communication occlusion and cost of the implant are the determinant factors of cost-effectiveness ratio. CONCLUSIONS: The proposal of a decision model seeks to fill a void in the academic literature. The decision model proposed includes the outcomes that present major impact in relation to the overall costs of the procedure. The atrial septal defects occlusion using percutaneous implant reduces the physical and psychological distress to the patients in relation to the conventional surgery, which represent intangible costs in the context of economic evaluation.

RESUMO

BACKGROUND: The most common congenital anomaly in adults is secundum, which can be closed using a surgical or transcatheter approach. Despite the growing use of transcatheter ASD closure, few studies have examined the cost-effectiveness of this strategy. We sought to compare the long-term cost effectiveness of transcatheter and surgical closure of secundum in adults. METHODS: A decision-analytic model was used with all clinical outcome parameter estimates obtained from the province-wide Québec Congenital Heart Disease Database. Costs were obtained from a single academic centre (Canadian dollars). A cost-effectiveness analysis using a discrete event Monte Carlo simulation model from the perspective of a single third party payer and multiple sensitivity analyses were performed. Patients were followed for a maximum of 5 years after ASD closure. RESULTS: Between l998 and 2005, we identified 718 adults (n=335 transcatheter; n=383 surgical) who underwent ASD closure in Quebec. The 5-year cost of surgical closure was $15,304 SD $4581 versus $11,060 SD $5169 for the transcatheter alternative. At 5 years, transcatheter closure was marginally more effective than surgery (4.683 SD 0.379 life-years versus 4.618 SD 0.638 life-years). Probabilistic sensitivity analyses demonstrated that transcatheter ASD closure was a dominant strategy with an 80% probability of cost savings and equal or greater efficacy compared to surgical treatment. CONCLUSION: Although definitive conclusions are limited given the observational nature of the primary data sources, transcatheter ASD closure appeared to be a cost-effective strategy associated with slightly improved clinical outcomes and reduced costs compared to surgical closure at 5-years follow-up.

RESUMO

BACKGROUND: The feasibility of fast-tracking children undergoing congenital heart disease surgery has not been assessed adequately. Current knowledge is based on limited single-center experiences without contemporaneous control groups. METHODS AND RESULTS: We compared administrative data for atrial septal defect (ASD) and ventricular septal defect (VSD) surgeries in children 2 months to 19 years of age at the Mount Sinai Medical Center (MSMC) with data from comparable patients at 40 centers contributing to the Pediatric Health Information System. Three-year blocks, early in and after fast tracking had been implemented at the MSMC, were examined. Seventy-seven and 89 children at MSMC undergoing ASD and VSD closure, respectively, were compared with 3103 ASD and 4180 VSD patients nationally. With fast tracking fully implemented, median length of stay at the MSMC decreased by 1 day compared with the earlier era (length of stay, 1 and 3 days for ASD and VSD, respectively). Nationally, median length of stay remained unchanged (3 days for ASD and 4 days for VSD) in the observed time periods. Hospitalization costs fell by 33% and 35% at MSMC (ASD and VSD, respectively), whereas they rose by 16% to 17% nationally. When analyzed in multiple regression models, the decrease in both length of stay and cost remained significantly greater at MSMC compared with nationally (P<0.0001 for all). Hospital mortality and 2-week readmission rates were unchanged at MSMC between the 2 time periods and were not different from the national rates. CONCLUSION: Shorter length of stay and cost savings compared with national data were observed after implementation of fast tracking.

RESUMO

OBJECTIVE: The study aims to evaluate the safety and feasibility of intra-operative device closure of atrial septal defect with transthoracic minimal invasion. METHODS: From May 2006 to June 2009, 252 patients with secundum-type atrial septal defect closure were enrolled in our institution. The patients were divided into two groups, with 182 patients in group I with intra-operative device closure and 72 in group II with surgical closure. In group I, the patients' age ranged from 3 months to 62 years (mean±standard deviation, 19.0±16.7 years). This approach involved a transthoracic minimal invasion that was performed after full evaluation of the atrial septal defect by transthoracic echocardiography, deploying the device through the delivery sheath to occlude the atrial septal defect. RESULTS: In group I, 180 patients were occluded successfully under this approach. The size of the occluder device implanted ranged from 6 to 48 mm. Minor complications occurred, which included transient arrhythmias (n=23) and pleural effusion (n=15). Two patients with postoperative cardiac arrest were successfully cardiopulmonary resuscitated. Another two patients with occluder dislodged back into the right atrium were turned to surgical repair with cardiopulmonary bypass on the postoperative day. In group II, all patients were occluded successfully, and almost all patients needed blood transfusion and suffered from various minor complications. All discharged patients were followed up for 1-5 years. During this period, we found no recurrence, no thrombosis, even no device failure. In our comparative studies, group II had significantly longer intensive care unit (ICU) stay and hospital stay than group I (p<0.05). The cost for group I was less than group II (p<0.05). CONCLUSIONS: Intra-operative device closure of atrial septal defect with transthoracic minimal invasion is a safe and feasible technique. It had the advantages of cost savings, yielding better cosmetic results, and leaving less trauma than surgical closure.

RESUMO

BACKGROUND: Congenital heart disease consumes significant health care resources; however, there are limited data regarding factors affecting resource utilization. The purpose of this study was to evaluate variation between centers in total hospital costs for 4 congenital heart operations of varying complexity and associated factors. METHODS AND RESULTS: The Premier Database was used to evaluate total cost in children undergoing isolated atrial septal defect (ASD) repair, ventricular septal defect (VSD) repair, tetralogy of Fallot (TOF) repair, or arterial switch operation (ASO) from 2001 to 2007. Mixed models were used to evaluate the impact of center on total hospital costs adjusting for patient and center characteristics and length of stay. A total of 2124 patients were included: 719 ASD (19 centers), 792 VSD (20 centers), 420 TOF (17 centers), and 193 ASO (13 centers). Total cost increased with complexity of operation from median $12 761 (ASD repair) to $55 430 (ASO). In multivariable analysis, models that accounted for center effects versus those that did not performed significantly better for all 4 surgeries (all P≤0.01). The proportion of total cost variation explained by center was 19% (ASD repair), 11% (VSD repair), 6% (TOF repair), and 3% (ASO). Higher-volume centers had significantly lower hospital costs for ASD and VSD repair but not for TOF repair and ASO. CONCLUSIONS: Total hospital costs varied significantly by center for all congenital heart surgeries evaluated, even after adjustment for patient and center characteristics and length of stay. Differences among centers were most prominent for lower complexity procedures.

RESUMO

INTRODUCTION: With advances in interventional catheterisation, transcatheter device closure of atrial septal defect (ASD) is now a feasible option to open heart surgery, especially in patients with isolated ASD. We aim to compare the outcomes, benefits and costs between device closure versus standard open-heart surgery for ASD in Singapore. MATERIALS AND METHODS: This is a comparative study between 2 cohorts with isolated secundum ASDs who underwent closure of ASD either by surgery or device, at the Department of Paediatrics, National University Hospital (NUH). The clinical outcomes, complications, length of stay and total costs incurred were compared. RESULTS: Surgical patients were at slightly greater risk of developing complications (RR=1.33; 95% CI, 0.30 to 5.95) than the device group. The median length of inpatient stay for the surgical group was significantly longer than that for the device group. Seventy percent of the patients in the device group did not need to be in ICU while 40% of patients in the surgery group stayed 2 or at least 3 days in ICU (P <0.001). The mean cost per successful procedure was $1511 (95% CI, -352 to 3375) higher for the device group patients despite a shorter length of stay in hospital. CONCLUSIONS: We concluded that transcatheter device closure is an effective and safe alternative to surgery in the treatment of suitable ASDs. Despite the high cost of the device, direct and indirect benefits for the patients and their families, who undergo device occlusion include less morbidity, better cosmesis, shorter length of stay in hospital, faster recovery and shorter time taken to resume normal activities.

RESUMO

OBJECTIVE: Intra-cardiac echocardiography (ICE) is used to guide percutaneous interventions on the atrial septum. However, ICE catheters are expensive. We questioned the impact of the use of ICE catheters on hospitalization costs for patent foramen ovale (PFO) or atrial septal defect (ASD) closure. METHODS AND RESULTS: Patients, scheduled for atrial septal closure, were randomly selected to use the AcuNav catheter (Biosense Webster Inc, Diamond Bar, CA, US) on top of the standard procedure (three or two days of hospitalization, procedure with transoesophageal echocardiography (TEE) and general anaesthesia). The AcuNav catheter was provided for free and the total hospitalization cost for each patient was calculated by verification of the bills, sent to the patient and the national health insurance. This was compared with a fictive hospitalization cost when ICE alone would have been used (three or two days of hospitalization, procedure without TEE, and local anaesthesia). Feasibility and safety were also evaluated. Three PFOs and two ASDs were successfully closed (3F/2M, age 55 +/- 12 years). The total hospitalization cost for a standard closing procedure was EUR 9345 +/- 132 and EUR 9303 +/- 132 for three and two days of hospitalization, respectively. With a free ICE catheter and no general anaesthesia, hospitalization cost lowered to EUR 8464 +/- 131 and EUR 8422 +/-131, respectively. Cost saving would be EUR 881 +/- 3, but the price of a single-use ICE catheter varies between EUR 2000 and 2500. In all patients, adequate images were obtained and no complications related to the ICE catheter occurred. CONCLUSIONS: Single-use ICE catheters remain expensive in percutaneous ASD or PFO closure. However, general anaesthesia might be avoided, which could open a discussion on cost savings.

RESUMO

OBJECTIVES: We compared the effectiveness and cost of percutaneous occlusion using an Amplatzer septal occluder (ASO) (AGA Medical Corp., Golden Valley, Minnesota) device compared with surgical closure of an ostium secundum atrial septal defect (ASD II) in Guatemala. BACKGROUND: The percutaneous occlusion of ASD II in first-world nations seems to offer better clinical results and lower cost compared with surgical closure. METHODS: We reviewed the clinical course of 111 patients referred to our institution for closure of isolated ASD II. Successful closure was assessed immediately after the procedures and at 12 months. Actual hospital costs were calculated for every patient who underwent either of the two procedures. RESULTS: Eighty-three patients with ASD II (75%) were selected for percutaneous occlusion with the ASO device, and the remaining 28 patients (25%) underwent surgical closure. In the device group, in 72 patients (86.7%) devices were successfully deployed. At immediate and 12-month follow-up, the complete closure rate was 87.5% (63 of 72 patients) and 97.2% (70 of 71 patients), respectively. In the surgical group, all patients had successful closure immediately after the procedure and at 12 months. Surgical closure offered a 27% cost savings in comparison with percutaneous occlusion (U.S. 3,329.50 dollars +/- 411.30 dollars and U.S. 4,521.03 dollars +/- 429.71 dollars; p < 0.001, respectively). Cost of the device (U.S. 2,930.00 dollars) proved to be the main cause for this difference. CONCLUSIONS: We confirmed the clinical advantages of percutaneous occlusion over surgical closure of ASD II. However, percutaneous occlusion costs were higher compared with surgical closure. In Guatemala, where health care resources are limited, ASD II closure with the ASO device did not prove to be cost-effective.

RESUMO

OBJECTIVE: The purpose of this study was to assess transfusion requirements in patients undergoing cardiac surgery with and without autologous blood donation and to calculate the costs of predonation from the hospital perspective. DESIGN: Observational study. SETTING: Single university hospital. PARTICIPANTS: Four thousand three hundred twenty-five patients undergoing elective cardiac surgery with and without autologous blood donation. INTERVENTIONS: Eight hundred forty-nine patients (20%) underwent autologous blood donation, whereas 3,476 (80%) did not. Perioperative allogeneic blood transfusion was recorded as the primary endpoint. To avoid selection bias, patients were stratified according to their preoperative risk score. A decision model was derived from acquired data for the optimization of autologous blood donation. MEASUREMENTS AND MAIN RESULTS: Allogeneic blood transfusion rate was 13% in patients with predonation versus 48% without predonation (p < 0.05). This difference remained statistically significant even after risk stratification. The predonation of 1, 2, or 3 units reduced the probability of receiving allogeneic blood to 24%, 14%, and 9%, respectively. An efficient program of predonation within the department of anesthesiology allowed keeping the costs of predonation low. Decision-tree analysis revealed that predonation of 2 autologous units of blood saved the most allogeneic blood for the smallest increase in costs. Incremental cost for male patients predonating 2 units was dollars 33 (US), whereas for females predonation could be done at no extra cost in comparison to patients without predonation. CONCLUSION: Autologous blood donation significantly reduces allogeneic blood requirement in cardiac surgery. If adjusted for diagnosis and gender, autologous blood donation is a cost-effective alternative to reduce allogeneic blood consumption.

RESUMO

BACKGROUND: While potential benefits of robotic technology include decreased morbidity and improved recovery, some have suggested a prohibitively high cost. This study was undertaken to compare actual hospital costs of robotically assisted cardiac procedures with conventional techniques. METHODS: We conducted a retrospective review of clinical and financial data of 20 patients who underwent atrial septal defect (ASD) closure and 20 patients who underwent mitral valve repair (MVr) using either robotic techniques or a conventional approach with a sternotomy. Total hospital cost (actual resource consumption) was subdivided into operative and postoperative costs. RESULTS: Robotic technology did not significantly increase total hospital cost for ASD closure or MVr (p = 0.518 and p = 0.539). However, when including the initial capital investment for the robot through amortization of institutional costs, total hospital cost was increased by $3,773 for robotic ASD closure and $3,444 for robotic MVr (p = 0.021 and p = 0.004). The major driver of cost for robotic cases (operating room time) decreased over time. CONCLUSIONS: Robotic technology did not significantly increase hospital cost. While the absolute cost for robotic surgery was higher than conventional techniques after taking into account the institutional cost of the robot, the major driver of cost for robotic procedures will likely continue to decrease, as the surgical team becomes increasingly familiar with robotic technology. Furthermore, other benefits, such as improvement in postoperative quality of life and more expeditious return to work may make a robotic approach cost-effective. Thus, it is possible that the benefits of robotic surgery may justify investment in this technology.
