Multi-institutional prostate cancer unit of Padova: Review of activity and performance indicators of the first 18 months after ISO9001 certification.

337 Background: The development of Prostate Cancer Units (PCUs) determined a paradigm shift in the treatment of this disease based on multidisciplinary management and shared clinical pathways among several specialists, but activities of PCUs are rarely reported. The Multi-Institutional PCU of Padova was decreed on Nov 2020 and involves Istituto Oncologico Veneto (IOV IRCCS), Azienda Ospedaliera-University of Padova (AOPD UNIPD) and Casa di Cura of Abano Terme. Padova PCU achieved the ISO 9001 certification on Dec 2020 and performance indicators were identified. Methods: We assessed clinical indicators of coordination, process and outcome of our PCU from 1st Jan 2021 to 30 Jun 2022. Data were extracted from the Electronic Medical Record ONCOSYS and from HEALTHMEETING, the software dedicated to register clinical information of patients, shared therapeutic decisions and participation of specialists to the PCU meetings. Results: A total of 739 consecutive pts were managed by the PCU in 18 months, generating a total of 1002 case discussions in 76 meetings, for a mean of 12,8 case discussions per week. Three Urology units performed 500 prostatectomies per year. Presence of at least one specialist for each core team specialty (either in presence of teleconference) was almost 100% with the exception of the pathologists, who were consulted mainly on demand. Waiting time for case discussion was always less than 2 weeks. Pts were presented by urologist, oncologist, radiation oncologist or other specialist in 46,3, 39,8, 10,5 and 3,4% of cases, respectively. They had localized/locally advanced, biochemically recurrent, metastatic castration-sensitive or castration-resistant disease in 43.3, 8, 28.2 and 20.5% of cases, respectively. Decision by the PCU was eventually carried out in 75,5% of cases, was changed due to pt’s preference of other reasons in 6.5%, or was still pending or not assessable in 18% of cases. Median time to completion of pathology report of prostatic biopsies was 8 days, median time from surgery to adjuvant radiotherapy was 5 months. Clinical trials with investigational drugs were proposed to 17% of pts with metastatic disease. Several process and outcome indicators (e.g., rate of active surveillance, rate of combined systemic therapy in men with metastatic castration sensitive cancer, survival of patients with metastatic castration resistant disease, etc.) could not be verified yet because they could not be extracted as aggregate data from institutional software and administrative databases. Conclusions: The volumes of Padova PCU and participation rate of core team specialists fulfill international requirements. Institutional software should be implemented in order to allow for aggregate data collection for the assessment of pre-defined performance indicators of PCU instead of reviewing the clinical chart of each prostate cancer pt.
