Simple SummaryThis German multicenter study investigated the importance of different supportive measures offered to patients with prostate cancer who undergo surgery (radical prostatectomy). A number of these supportive measures are required during the certification of a urologic hospital as prostate cancer center. However, a broad scientific basis evaluating these measures from the patient’s perspective is still lacking. In this study, patients were asked to rate the relevance of several supportive measures and to estimate the effective availability of these different supportive measures at their urologic clinic about 15 months after surgery. Our study highlights that only six of fifteen different supportive measures were rated as very relevant by patients. None of these six supportive measures were offered more intensively at the certified clinics compared to the non-certified clinics according to the patients. Our study helps to identify those supportive measures with the highest subjective impact on patients in this setting.AbstractCertification as a prostate cancer center requires the offer of several supportive measures to patients undergoing radical prostatectomy (RP). However, it remains unclear how patients estimate the relevance of these measures and whether the availability of these measures differs between certified prostate cancer centers (CERTs) and non-certified centers (NCERTs). In 20 German urologic centers, a survey comprising questions on the relevance of 15 supportive measures was sent to 1000 patients at a median of 15 months after RP. Additionally, patients were asked to rate the availability of these measures using a four-item Likert scale. The aim of this study was to compare these ratings between CERTs and NCERTs. The response rate was 75.0%. In total, 480 patients underwent surgery in CERTs, and 270 in NCERTs. Patients rated 6/15 supportive measures as very relevant: preoperative medical counselling concerning treatment options, a preoperative briefing answering last questions, preoperative pelvic floor exercises (PFEs), postoperative PFEs, postoperative social support, and postoperative rehabilitation addressing physical fitness recovery. These ratings showed no significant difference between CERTs and NCERTs (p= 0.133–0.676). In addition, 4/9 of the remaining criteria were rated as more detailed by patients in CERTs. IMPROVE represents the first study worldwide to evaluate a patient-reported assessment of the supportive measures accompanying RP. Pertinent offers vary marginally between CERTs and NCERTs.
