The Development of Robotic Technology in Cardiac and Vascular Interventions.

ABSTRACT: Robotic technology has been used in cardiovascular medicine for over a decade, and over that period its use has been expanded to interventional cardiology and percutaneous coronary and peripheral vascular interventions. The safety and feasibility of robotically assisted interventions has been demonstrated in multiple studies ranging from simple to complex coronary lesions, and in the treatment of iliofemoral and infrapopliteal disease. These studies have shown a reduction in operator exposure to harmful ionizing radiation, and the use of robotics has the intuitive benefit of alleviating the occupational hazard of operator orthopedic injuries. In addition to the interventional operator benefits, robotically assisted intervention has the potential to also be beneficial for patients by allowing more accurate lesion length measurement, stent placement, and patient radiation exposure; however, more investigation is required to elucidate these benefits fully.

Project description:BackgroundProstate cancer is the second most common type of cancer in Canadian men. Radical prostatectomy is one of the treatment options available, and involves removing the prostate gland and surrounding tissues. In recent years, surgeons have begun to use robot-assisted radical prostatectomy more frequently. We aimed to determine the clinical benefits and harms of the robotic surgical system for radical prostatectomy (robot-assisted radical prostatectomy) compared with the open and laparoscopic surgical methods. We also assessed the cost-effectiveness of robot-assisted versus open radical prostatectomy in patients with clinically localized prostate cancer in Ontario.MethodsWe performed a literature search and included prospective comparative studies that examined robot-assisted versus open or laparoscopic radical prostatectomy for prostate cancer. The outcomes of interest were perioperative, functional, and oncological. The quality of the body of evidence was examined according to the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) Working Group criteria. We also conducted a cost-utility analysis with a 1-year time horizon. The potential long-term benefits of robot-assisted radical prostatectomy for functional and oncological outcomes were also evaluated in a 10-year Markov model in scenario analyses. In addition, we conducted a budget impact analysis to estimate the additional costs to the provincial budget if the adoption of robot-assisted radical prostatectomy were to increase in the next 5 years. A needs assessment determined that the published literature on patient perspectives was relatively well developed, and that direct patient engagement would add relatively little new information.ResultsCompared with the open approach, we found robot-assisted radical prostatectomy reduced length of stay and blood loss (moderate quality evidence) but had no difference or inconclusive results for functional and oncological outcomes (low to moderate quality evidence). Compared with laparoscopic radical prostatectomy, robot-assisted radical prostatectomy had no difference in perioperative, functional, and oncological outcomes (low to moderate quality evidence). Compared with open radical prostatectomy, our best estimates suggested that robot-assisted prostatectomy was associated with higher costs ($6,234) and a small gain in quality-adjusted life-years (QALYs) (0.0012). The best estimate of the incremental cost-effectiveness ratio (ICER) was $5.2 million per QALY gained. However, if robot-assisted radical prostatectomy were assumed to have substantially better long-term functional and oncological outcomes, the ICER might be as low as $83,921 per QALY gained. We estimated the annual budget impact to be $0.8 million to $3.4 million over the next 5 years.ConclusionsThere is no high-quality evidence that robot-assisted radical prostatectomy improves functional and oncological outcomes compared with open and laparoscopic approaches. However, compared with open radical prostatectomy, the costs of using the robotic system are relatively large while the health benefits are relatively small.
