Abstract

Objective: The majority of cost-studies related to robotic surgery has a short follow-up and primarily report the costs from the index surgery. The aim of this study was to evaluate the long-term resource consequences of introducing robotic surgery for early stage endometrial cancer in Denmark. Methods: The study included all women with early stage endometrial cancer who underwent robotic, laparoscopic and open access surgery from January 2008 to June 2015. Data was linked from national databases to determine resource consumption and costs from hospital treatments, outpatient contacts, primary health care sector visits, labor market affiliation and prescription of medication. Each patient was observed in a period of 12 months before- and after surgery. The key exposure variable was women who were exposed to robotic surgery compared to those who were not. Results: A total of 4133 women underwent surgery for early stage endometrial cancer. The study found additional costs of $7309 (95% confidence interval [CI] 2100–11,620, P = 0.001) per patient in the group exposed to robotic surgery including long-term costs post-surgery compared to the non-exposed group (non-robotic group). When controlling for time trends, the introduction of robotic surgery did not reduce the number of bed days (mean diff −0.42, 95% CI −3.03–2.19, P = 0.752). Conclusions: The introduction of robotic surgery for early stage endometrial cancer did not generate any long-term cost savings. The additional costs of robotic surgery were primarily driven by the index surgery. Any reduction in bed days could be explained by time trends.
