National Robotics-Assisted Radical Prostatectomy Database

Radical Prostatectomy (RP) is the only surgical option for resectable PCA with evidenced benefit for overall survival \[5,6\]. Robotic-Assisted Radical Prostatectomy (RARP) is an evolved RP represents a significant advancement in PCa treatment offering better field of vision \& dexterity for the surgeons \[7,8,9,10,11\] compared to other procedures such as Open Radical Prostatectomy (ORP) and Laparoscopic Radical prostatectomy (LRP). A meta-analysis \[12\] of Randomized Control Trials (RCT) and non-randomized studies reported that RARP and LRP were similar in terms of blood loss, catheter indwelling time, overall complication rate, overall positive surgical margin and biochemical recurrence rates. However, quantitative synthesis of non-randomized studies indicated that RARP was associated with better functional and oncological outcomes compared to LRP. Despite RARP holding promising benefits, it also presents some potential challenges such as: 1. Learning curve - Surgeons require significant training and experience to become proficient in using robotic systems. This learning curve can impact surgical outcomes, especially in less experienced hands. 2. Cost - The robotic systems and associated instruments are expensive, leading to higher upfront costs for hospitals. This can translate to higher costs for patients and healthcare systems. 3. Disparity between private and public sectors: availability of robotic surgery can be limited by geographic and economic factors, potentially leading to disparities in access to advanced surgical option. A retrospective audit of all RARP procedures performed at high volume centre in Australia highlighted, operating time costs for RARP is $134.16 AUD per minute which costs the patient and the hospital $30, 588.48 AUD per case. The health industry average costs for a RARP procedure is 32,199 AUD per case. A transition point of 65 cases at the industry average will cost up to $2,092,935 AUD to consistent primary outcomes for patients \[13\]. Surgeon's experience and efficiency become an important determinant of post RARP outcomes. Incorporating assessment protocols and intensive training programs might contribute to better post RARP outcomes \[14\]. Another Australian study \[15\] evaluated the ORP versus RARP outcomes at a high-volume centre. Results of the study indicated significantly lower mean Length of Stay (LOS) for RARP compared with ORP (1.2 vs 4.4 days) and a much higher readmission rate after ORP (19%) compared with RARP (2%). Though the study reported evidenced benefits, it also highlighted that case-mix funding model failed to adequately reimburse the public hospitals for RARP when compared with ORP despite efficient use of hospital resources in terms of hospital stay and reduction in costly readmissions. A massive inequality gap exists between the public and private sectors. A retrospective analysis of Victorian Cancer Registry data found proportion of private patients who underwent radical prostatectomy (44%) was larger than that for public patients (28%). \[16\] There are fewer robots in the public sector compared to private hospitals hence public patients are offered alternate approaches. A barrier to the uptake of robotic-assisted surgery (RAS) continues to be the perceived high costs. A lack of detailed costing information has made it difficult for public hospitals in particular to determine whether use of the technology is justified \[17\]. This inconsistency in approach and lack of detail makes it difficult for local hospital administrators, health ministries and governing bodies to determine whether the costs of the technology are reasonable and worth the ongoing investment, and has the potential to impact on future strategic decision-making. It is notable, that robust evidence substantiating the advantages of robotic surgery from high volume centres is currently insufficient. The acquisition of high-quality evidence pertaining to surgical techniques poses a formidable challenge \[18\]. Robust investigations, characterized by substantial scale and comparativeness, are imperative for a comprehensive assessment of the surgical, oncological and Patient reported outcomes along with learning curves of surgeons associated with RARP. There is an imperative need for the establishment of a population-based database that systematically captures a comprehensive array of surgical operatives, learning curves of surgeons and the patient-reported quality of life measures (PROM). A structured database holds the potential to provide a standardized framework, enabling robust comparative analyses, trend identification, and the formulation of evidence-based guidelines for the individualized management of prostate cancer.
