Aim: To evaluate 90-day episode-of-care (EOC) costs associated with robotic-arm assisted total knee arthroplasty (rTKA) versus manual TKA (mTKA). Patients & methods: TKA procedures were identified in Medicare 100% data. Accounting for baseline differences, propensity score matching was performed 1:5. 90-day EOC and index costs, lengths-of-stay, discharge disposition and readmission rates were assessed. Results: A total of 519 rTKA and 2595 mTKA were included. Overall 90-day EOC costs were US$2391 less for rTKA (p < 0.0001). Over 90% of patients in both cohorts utilized post-acute services, with rTKA accruing fewer costs than mTKA. Post-acute savings can be attributed to discharge destination. Conclusion: rTKA incurred an overall lower 90-day EOC cost versus mTKA. Savings were driven by fewer readmissions and an economically beneficial discharge destinations.

Background Anastomotic leaks cause a significant clinical and economic burden on patients undergoing bariatric and colorectal surgeries. Current literature shows a wide variation in incidence of anastomotic leaks and a significant gap in associated economic metrics. This analysis utilized claims data to quantify the full episode-of-care cost burden of leaks following colorectal and bariatric surgeries. Methods Medicare Fee-for-Service and commercial claims data from a large U.S.-based health plan were queried for cost and utilization of members that underwent bariatric and colorectal surgical procedures between January 1, 2013 and August 31, 2015. Outcomes were collected for members with anastomotic leaks versus those without leaks during the initial hospital stay (index) and within 30 days of the procedure. These outcomes included leak frequency, payer reimbursement, and length of stay (LOS). Results The colorectal Medicare analysis identified 239,350 patients undergoing colorectal surgery. For patients with a leak compared to those without, index admission costs were $30,670 greater ($48,982 vs. $18,312; p < 0.0001) and the index LOS was 12 days longer (19 vs. 7 days; p < 0.0001). This finding was similar for the bariatric patients (n = 62,292) where cost was $30,885 higher ($43,918 vs. $13,033; p < 0.0001) and LOS was 15 days longer (17 vs. 2 days; p < 0.0001). Furthermore, readmissions and associated costs were also substantially higher for those with an index leak. The commercial analysis of both the bariatric and colorectal populations trended similarly to the Medicare population in regards to all outcomes measured. Conclusion Patients experiencing anastomotic leaks during and after bariatric and colorectal surgery have significantly higher costs and longer LOS both at the initial stay and within 30 days of the procedure. It is important that providers and hospitals understand the economic consequences of these procedures and implement technologies and techniques to prevent/ reduce anastomotic leaks.

This study performed a health care utilization analysis between robotic arm assisted total knee arthroplasty (rTKA) and manual total knee arthroplasty (mTKA) techniques. Specifically, we compared (1) index costs and (2) discharge dispositions, as well as (3) 30-day (4) 60-day, and (5) 90-day (a) episode-of-care costs, (b) postoperative health care utilization, and (c) readmissions. The 100% Medicare Standard Analytical Files were used for rTKAs and mTKAs performed between January 1, 2016, and March 31, 2017. Based on strict inclusion–exclusion criteria and 1:5 propensity score matching, 519 rTKA and 2,595 mTKA patients were analyzed. Total episode payments, health care utilization, and readmissions, at 30-, 60-, and 90-day time points were compared using generalized linear model, binomial regression, log link, Mann–Whitney, and Pearson's chi-square tests. The rTKA versus mTKA cohort average total episode payment was US$17,768 versus US$19,899 (p < 0.0001) at 30 days, US$18,174 versus US$20,492 (p < 0.0001) at 60 days, and US$18,568 versus US$20,960 (p < 0.0001) at 90 days. At 30 days, 47% fewer rTKA patients utilized skilled nursing facility (SNF) services (13.5 vs. 25.4%; p < 0.0001) and had lower SNF costs at 30 days (US$6,416 vs. US$7,732; p = 0.0040), 60 days (US$6,678 vs. US$7,901, p = 0.0072), and 90 days (US$7,201 vs. US$7,947, p = 0.0230). rTKA patients also utilized fewer home health visits and costs at each time point (p < 0.05). Additionally, 31.3% fewer rTKA patients utilized emergency room services at 30 days postoperatively and had 90-day readmissions (5.20 vs. 7.75%; p = 0.0423). rTKA is associated with lower 30-, 60-, and 90-day postoperative costs and health care utilization. These results are of marked importance given the emphasis to contain and reduce health care costs and provide initial economic insights into rTKA with promising results.

Among the cases captured by the Medicare database, catheter ablation of VT associated with mechanical support using PVAD was associated with reduced in-hospital cardiogenic shock, renal failure, length of stay, hospital readmissions and mortality, but no difference in redo-VT ablation at 1 year.
