Assessing the cost effectiveness of robotics in urological surgery – a systematic review

Assessing the cost effectiveness of robotics in urological surgery – a systematic review Study Type – Therapy (systematic review) Level of Evidence 1a What's known on the subject? and What does the study add? Research on the subject has shown that robotic surgery is more costly than both laparoscopic and open approaches due to the initial cost of purchase, annual maintenance and disposable instruments. However, both robotic and laparoscopic approaches have reduced blood loss and hospital stay and robotic procedures have better short term post‐operative outcomes such as continence and sexual function. Some studies indicate that the robotic approach may have a shorter learning curve. However, factors such as reduced learning curve, shorter hospital stay and reduced length of surgery are currently unable to compensate for the excess costs of robotic surgery. This review concludes that robotic surgery should be targeted for cost efficiency in order to fully reap the benefits of this advanced technology. The excess cost of robotic surgery may be compensated by improved training of surgeons and therefore a shorter learning curve; and minimising costs of initial purchase and maintenance. The review finds that only a few studies gave an itemised breakdown of costs for each procedure, making accurate comparison of costs difficult. Furthermore, there is a lack of long term follow up of clinical outcomes, making it difficult to accurately assess long term post‐operative outcomes. A breakdown of costs and studies of long term outcomes are needed to accurately assess the effectiveness of robotic surgery in urology.

Abstract

Study Type – Therapy (systematic review) Level of Evidence 1a What's known on the subject? and What does the study add? Research on the subject has shown that robotic surgery is more costly than both laparoscopic and open approaches due to the initial cost of purchase, annual maintenance and disposable instruments. However, both robotic and laparoscopic approaches have reduced blood loss and hospital stay and robotic procedures have better short term post‐operative outcomes such as continence and sexual function. Some studies indicate that the robotic approach may have a shorter learning curve. However, factors such as reduced learning curve, shorter hospital stay and reduced length of surgery are currently unable to compensate for the excess costs of robotic surgery. This review concludes that robotic surgery should be targeted for cost efficiency in order to fully reap the benefits of this advanced technology. The excess cost of robotic surgery may be compensated by improved training of surgeons and therefore a shorter learning curve; and minimising costs of initial purchase and maintenance. The review finds that only a few studies gave an itemised breakdown of costs for each procedure, making accurate comparison of costs difficult. Furthermore, there is a lack of long term follow up of clinical outcomes, making it difficult to accurately assess long term post‐operative outcomes. A breakdown of costs and studies of long term outcomes are needed to accurately assess the effectiveness of robotic surgery in urology.
