Title:
Robotic-assisted surgery for prostatectomy
:
does the diffusion of robotic systems contribute to treatment centralization and influence patients’ hospital choice?
Description:
Background Between 2008 and 2018, the share of robotic-assisted surgeries (RAS) for radical prostatectomies (RPEs) has increased from 3 to 46% in Germany. Firstly, we investigate if this difusion of RAS has contributed to RPE treatment centralization. Secondly, we analyze if a hospital's use of an RAS system infuenced patients' hospital choice. Methods To analyze RPE treatment centralization, we use (bi-) annual hospital data from 2006 to 2018 for all German hospitals in a panel-data fxed efect model. For investigating RAS systems' infuence on patients' hospital choice, we use patient level data of 4614 RPE patients treated in 2015. Employing a random utility choice model, we estimate the infuence of RAS as well as specialization and quality on patients' marginal utilities and their according willingness to travel. Results Despite a slight decrease in RPEs between 2006 and 2018, hospitals that invested in an RAS system could increase their case volumes signifcantly (+82% compared to hospitals that did not invest) contributing to treatment centralization. Moreover, patients are willing to travel longer for hospitals ofering RAS (+22% than average travel time) and for specialization (+13% for certifed prostate cancer treatment centers,+9% for higher procedure volume). The infuence of outcome quality and service quality on patients' hospital choice is insignifcant or negligible. Conclusions In conclusion, centralization is partly driven by (very) high-volume hospitals' investment in RAS systems and patient preferences. While outcome quality might improve due to centralization and according specialization, evidence for a direct positive infuence of RAS on RPE outcomes still is ambiguous. Patients have been voting with their feet, but research yet has to catch up.
