ItemQuality of handwritten surgical operative notes from surgical trainees: a noteworthy issue(WILEY, 2019-03)BACKGROUND: Surgical operation notes are crucial for medical record keeping and information flow in continued patient care. In addition to inherent medical implications, the quality of operative notes also has important economic and medico-legal ramifications. Further, well-documented records can also be useful for audit purposes and propagation of research, facilitating the improvement of delivery of care to patients. We aimed to assess the quality of surgical operation notes written by junior doctors and trainees against a set standard, to ascertain whether these standards were met. METHOD: We undertook an audit of Urology and General Surgery operation notes handwritten by junior doctors and surgical trainees in a tertiary teaching hospital over a month period both in 2014 and 2015. Individual operative notes were assessed for quality based on parameters described by the Royal College of Surgeons of England guidelines. RESULTS: Based on the Royal College of Surgeons of England guidelines, a significant proportion of analysed surgical operative notes were incomplete, with information pertaining to the time of surgery, name of anaesthetist and deep vein thrombosis prophylaxis in particular being recorded less than 50% of the time (22.42, 36.36 and 43.03%, respectively).Overall, 80% compliance was achieved in 14/20 standards and 100% compliance was attained in only one standard. CONCLUSIONS: The quality of surgical operation notes written by junior doctors and trainees demonstrated significant deficiencies when compared against a set standard. There is a clear need to educate junior medical staff and to provide systems and ongoing education to improve quality. This would involve leadership from senior staff, ongoing audit and the development of systems that are part of the normal workflow to improve quality and compliance.

ItemTrends in the surgical treatment of benign prostatic hyperplasia in a tertiary hospital(WILEY, 2018-01)BACKGROUND: To assess current treatment trends and perioperative outcomes of transurethral resection of the prostate (TURP) and photoselective vaporization of the prostate (PVP) in a tertiary institution. METHODS: We prospectively collected a database of all patients undergoing TURP and PVP for benign prostatic hyperplasia (BPH) at a tertiary hospital between January 2011 and December 2013. Patient characteristics such as length of stay, readmission, anticoagulation status, American Society of Anesthesiologists (ASA) score and need for blood transfusion were recorded and analysed. RESULTS: In total, 560 cases were included: 204 (36.4%) underwent TURP and 356 (63.6%) PVP. Patients undergoing PVP had higher ASA scores (P < 0.001) and were more frequently on continuing anticoagulant therapy (P < 0.001). With regards to non-aspirin/asasantin coagulation therapy, 61 (17.1%) patients underwent PVP with their anticoagulants continued while no patients who received TURP continued anticoagulation. Blood transfusion percentages were similar at 1.0% for TURP and 1.7% for PVP but readmission proportions were higher after PVP (32 patients, 9.0%) compared to TURP (10 patients, 4.9%). These differences were attenuated when excluding patients continuing anticoagulation during the procedure. CONCLUSION: At our institution, the use of PVP has been increasing on a year-by-year basis. The results of the current study demonstrated that PVP is safe in patients with increased anaesthetic risk or on active anticoagulation when compared to traditional TURP. While this makes PVP an attractive alternative to TURP in high-risk anticoagulated patients, these patients may have complex post-discharge issues that should be addressed during the informed consent process.

ItemNear-infrared spectroscopy in the diagnosis of testicular torsion: valuable modality or waste of valuable time? A systematic review(WILEY, 2020-05)BACKGROUND: Testicular torsion (TT) is a urological emergency that affects one in 4000 males younger than 25 years. Delays in the management of TT may result in testicular ischaemia, testicular necrosis, orchidectomy and infertility. This review assesses the validity of near-infrared spectroscopy (NIRS) as a diagnostic tool in the assessment and diagnosis of TT. METHODS: A systematic search of Cochrane Database of Systematic Reviews, EMBASE, Google Scholar, PubMed, Scopus and Web of Science databases was performed in January 2019 using specific search terms. Selected studies were ranked and evaluated using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and the Quality Assessment of Diagnostic Accuracy Studies-2 tool. RESULTS: A total of nine studies that included 253 subjects (88 animals and 165 humans) with a mean sample size of 28.1 (standard deviation 40.8) subjects were included. The mean difference in testicular tissue oxygen saturation between torsed and non-torsed testes (Δ%StO2 ) were 45%, 42% (±5%), 26% and 5-18% in four animal studies and 2.0%, 3.0%, 6.7%, 6.8% and 23.0% in five human studies. The tissue oxygen saturation difference between contralateral healthy testes (controls) ranged from 1% to 10% in the five studies that alluded to this. CONCLUSION: The current body of evidence does not support the use of NIRS in the work-up of TT. Well-designed clinical trials with large patient samples are required to determine whether NIRS may have some future role as a diagnostic modality in TT.

ItemDeclining use of radical prostatectomy and pelvic lymphadenectomy despite more robotics: National population data over 15 years(WILEY, 2020-04)AIM: To describe national surgical patterns of prostate cancer (PCa) care considering radical prostatectomy with or without pelvic lymphadenectomy and consideration of robotic-assisted techniques. METHODS: Retrospective analysis of publicly accessible Medicare claims data was performed for the period 2001-2016 and included patients undergoing radical prostatectomy with or without pelvic lymphadenectomy relative to total and PCa-specific populations among men aged 45-84 years. Proportion of cases performed robotically was considered. RESULTS: Total procedures performed increased from 2001, peaked in 2009 and subsequently decreased until 2016. Since 2009, the age-specific rate of surgery in men aged 75-84 increased by 2.3-fold, whereas the rates for men aged 55-64 and 45-54 reduced by 44% and 55%, respectively. Rates of concurrent pelvic lymphadenectomy fell until 2009 with subsequent stabilization (ratio 1.05-1.14) through to 2016. Significant regional practice patterns were observed, as was an increasing trend toward a robotic-assisted laparoscopic approach, comprising more than 80% of radical prostatectomies in 2016. CONCLUSION: Since the peak in 2009, radical prostatectomy is performed less in men <65 years and more in men ≥65 years. An increasing proportion of cases omit concurrent pelvic lymphadenectomy and are performed robotically.

ItemPatterns of primary staging for newly diagnosed prostate cancer in the era of prostate specific membrane antigen positron emission tomography: A population-based analysis(WILEY, 2021-10)INTRODUCTION: There has been a growing body of evidence highlighting the improved sensitivity and specificity for prostate specific membrane antigen (PSMA) positron emission tomography (PET) in advanced prostate cancer imaging. We aimed to assess prostate cancer staging practice patterns in Australia using population-based data. SUBJECT AND METHODS: We extracted data on men diagnosed with prostate cancer between October 2016 and December 2018 from the Prostate Cancer Outcomes Registry-Victoria (PCOR-Vic). We evaluated trends and comparisons between patients receiving PET/CT (with or without conventional imaging (CImg)), and CImg alone, and analysed imaging modality as predictor of clinical regional node positive disease (cN1 vs cN0/X), metastatic disease (cM1 vs cM0/X), and treatment received. RESULTS: In total, 6139 patients in the registry had either a staging PET scan (n = 889, 14%), CImg without PET scan (n = 2464, 40%), or no recorded PET or CImg (n = 2786, 45%). The proportion of allimaged patients who received staging PET increased from 19% to 36% from the first to last three-month period, and in the high-risk category the increase was 23-43%. After adjustment for grade group, PET vs CImg-only patients were observed to have a higher proportion of cN1 disease (OR = 2.46, 95% CI: 1.90-3.20) but not cM1 disease (OR = 1.10, 95% CI: 0.84-1.44). CONCLUSIONS: Our registry data highlights the rapid uptake of PET imaging, particularly in high-risk disease. Based on this data, we highlight the increased diagnosis of nodal disease, thus potentially optimizing patient selection prior to definitive treatment for prostate cancer.
