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.

ItemProstate-specific membrane antigen-positron emission tomography/computed tomography (PSMA-PET/CT)-guided stereotactic ablative body radiotherapy for oligometastatic prostate cancer: a single-institution experience and review of the published literature(WILEY, 2019-11)OBJECTIVES: To report the outcomes of stereotactic ablative body radiotherapy (SABR) in men with oligometastatic prostate cancer (PCa) diagnosed on prostate-specific membrane antigen (PSMA)-positron emission tomography/computed tomography (PET/CT), based on a single-institution experience and the published literature. PATIENTS AND METHODS: This was a retrospective cohort study of the first 20 consecutive men with oligometastatic PCa, treated with SABR in a single institution, who had biochemical recurrence after previous curative treatment (surgery/radiotherapy), had no evidence of local recurrence, were not on palliative androgen deprivation therapy (ADT), and had PSMA-PET/CT-confirmed oligometastatic disease (≤3 lesions). These men were treated with SABR to a dose of 30 Gy in three fractions for bone metastases, and 35-40 Gy in five fractions for nodal metastases. The outcomes of interest were: PSA response; local progression-free survival (LPFS); distant progression-free survival (DPFS); and ADT-free survival (ADTFS). A literature review was performed to identify published studies reporting on outcomes of PSMA-PET/CT-guided SABR. RESULTS: In our institutional cohort, 12 men (60%) had a decline in PSA post-SABR. One man had local progression 9.6 months post-SABR, with 12-month LPFS of 93%. Ten men had distant progression outside of their SABR treatment field, confirmed on PSMA-PET/CT, with 12-month DPFS of 62%, of whom four were treated with palliative ADT, two received prostate bed radiotherapy for prostate bed progression (confirmed on magnetic resonance imaging), and four received a further course of SABR (of whom one had further progression and was treated with palliative ADT). At last follow-up, six men (one with local progression and five with distant progression) had received palliative ADT. The 12-month ADTFS was 70%. Men with longer intervals between local curative treatment and SABR had better DPFS (P = 0.03) and ADTFS (P = 0.005). Four additional studies reporting on PSMA-PET/CT-guided SABR for oligometastatic PCa were identified and included in the review, giving a total of 346 patients. PSA decline was reported in 60-70% of men post-SABR. The 2-year LPFS, DPFS and ADTFS rates were 76-100%, 27-52%, and 58-62%, respectively. CONCLUSION: Our results showed that PSMA-PET/CT could have an important role in identifying men with true oligometastatic PCa who would benefit the most from metastases-directed therapy with SABR.

ItemFactors associated with spontaneous stone passage in a contemporary cohort of patients presenting with acute ureteric colic: results from the Multi-centre cohort study evaluating the role of Inflammatory Markers In patients presenting with acute ureteric Colic (MIMIC) study(WILEY, 2019-09)OBJECTIVES: To assess the relationship of white blood cell count (WBC) and other routinely collected inflammatory and clinical markers including stone size, stone position, and medical expulsive therapy use (MET), with spontaneous stone passage (SSP) in a large contemporary cohort of patients with acute ureteric colic, as there are conflicting data on the role of WBC and other inflammatory markers in SSP in patients with acute ureteric colic. PATIENTS AND METHODS: Multicentre retrospective cohort study coordinated by the British Urology Researchers in Surgical Training (BURST) Research Collaborative at 71 secondary care hospitals across four countries (UK, Republic of Ireland, Australia, and New Zealand). In all, 4170 patients presented with acute ureteric colic and a computed tomography confirmed single ureteric stone. Our primary outcome measure was SSP, as defined by the absence of need for intervention to assist stone passage (SP). Multivariable mixed effects logistic regression was used to explore the relationship between key patient factors and SSP. RESULTS: In all, 2518 patients were discharged with conservative management and had further follow-up with a SSP rate of 74% (n = 1874/2518). Sepsis after discharge with conservative management was reported in 0.6% (n = 16/2518). On multivariable analysis neither WBC, neutrophils count, nor C-reactive protein (CRP) predicted SSP, with an adjusted odds ratio (OR) of 0.97 (95% confidence interval [CI] 0.91-1.04, P = 0.38), 1.06 (95% CI 0.99-1.13, P = 0.1) and 1.00 (95% CI 0.99-1.00, P = 0.17), respectively. MET also did not predict SSP (adjusted OR 1.11, 95% CI 0.76-1.61). However, stone size and stone position were significant predictors. SSP for stones <5 mm was 89% (95% CI 87-90) compared to 49% (95% CI 44-53) for stones ≥5-7 mm, and 29% (95% CI 23-36) for stones >7 mm. For stones in the upper ureter the SSP rate was 52% (95% CI 48-56), middle ureter was 70% (95% CI 64-76), and lower ureter was 83% (95% CI 81-85). CONCLUSION: In contrast to the previously published literature, we found that in patients with acute ureteric colic who are discharged with initial conservative management neither WBC, neutrophil count, nor CRP, helps determine the likelihood of SSP. We also found no overall benefit from the use of MET. Stone size and position are important predictors and our present findings represent the most comprehensive SP rates for each millimetre increase in stone size from a large contemporary cohort adjusting for key potential confounders. We anticipate that these data will aid clinicians managing patients with acute ureteric colic and help guide management decisions and the need for intervention.

ItemAdverse impact of malnutrition markers on major abdominopelvic cancer surgery(WILEY, 2019-05)BACKGROUND: Malnutrition has been associated with adverse postoperative outcomes in a range of procedures but none have evaluated the interaction between clinical indicators of malnutrition. We aimed to comparatively evaluate how combinations of nutritional parameters impact postoperative outcomes amongst patients undergoing major cancer operations. METHODS: Major abdominopelvic cancer surgery cases (colectomy, cystectomy, esophagectomy, gastrectomy, hysterectomy, nephrectomy, pancreatectomy, pneumonectomy and prostatectomy) were identified in the American College of Surgeons National Surgical Quality Improvement Program database from 2007-2016. Malnutrition was defined by the presence of the following parameters: body mass index <18.5 kg/m2 ; preoperative serum albumin <3.0 g/dL or more than 10% weight loss in the last 6 months. Malnourished cases were matched with cases with satisfactory nutritional status using propensity scores. The primary outcome was the incidence of Clavien III-IV complications. RESULTS: Of the 30 207 cases included, 8.5% had at least one marker of malnutrition. The incidence of Clavien III-IV complications across all cases was 5.8%. In the matched cohort, malnourished cases had a higher rate of complications than those with adequate nutritional status (11.3% versus 9.6%, P = 0.018). A correlation was observed between the number of malnutrition markers possessed and the incidence of Clavien III-V complications. Cases with all three makers had the highest likelihood of experiencing a complication (odds ratio 5.47, 95% confidence interval 1.85-16.17). CONCLUSION: Poor nutritional status confers an increased risk of major postoperative complications and being discharged to a facility in non-upper gastrointestinal cancer patients. There was a correlation between the number of malnutrition parameters and the risk of complications.

ItemHigh dose rate brachytherapy boost for prostate cancer: Biochemical control and the impact of transurethral resection of the prostate and hydrogel spacer insertion on toxicity outcomes(WILEY, 2019-06)INTRODUCTION: To examine the long-term outcomes of high dose rate brachytherapy boost (HDR-BT) combined with external beam radiotherapy (EBRT) for intermediate and high-risk prostate cancer patients. METHODS: Data from 95 patients who underwent combined EBRT (50.4 Gy) and HDR-BT to the prostate between 2010 and 2017 were retrospectively analysed. Biochemical progression free survival (bPFS), local recurrence free survival (LRFS), metastatic free survival (MFS) and overall survival (OS) were estimated using Kaplan-Meier method. Regression analysis was conducted to identify important predictors of outcomes. RESULTS: A total of 24 patients received an initial HDR-BT dose of 18 Gy in three fractions, with the remaining 71 patients receiving 16 Gy in two fractions as per departmental protocol changes. Most patients (88%) received androgen deprivation therapy. A transurethral resection of the prostate (TURP) was performed in 14 patients and hydrogel spacers (HS) were used in 30 patients. Median follow-up was 58 months. The 5-year bPFS, LRFS, MFS and OS were 92%, 100%, 92% and 88%. Univariate regression revealed no statistical association between patient characteristics and time to relapse (all P > 0.1). Late > grade 2 genitourinary (GU) toxicity was 6.3%. The use of HS or prior TURP had no impact on late GU toxicity. Late Grade 1 gastrointestinal (GI) toxicity was 5.3%. CONCLUSION: The combined HDR-BT with EBRT resulted in excellent bPFS. The cumulative risk of late GU and GI toxicity was low and can be further improved with preventative strategies such as a pre-emptive TURP and/or HS insertion.

ItemAnalysis of social media use among Australian and New Zealand otolaryngologists(WILEY, 2019-06)BACKGROUND: Social media's rapid worldwide growth has permeated surgical practice. To date, no study has evaluated social media use amongst Australian and New Zealand otolaryngologists. METHODS: Cross-sectional study of all members of the Australian and New Zealand Societies of Otolaryngology Head and Neck Surgery with comprehensive searches of websites and social media platforms (Facebook, Twitter, LinkedIn, ResearchGate and Instagram) was performed. RESULTS: A total of 498 otolaryngologists were identified with 81.7% working in Australia; 79.1% had some form of online presence - either professional website or activity on ≥1 social media platform and 53.0% of otolaryngologists had a professional website and mean number of social media profiles averaged 1.35 per surgeon. LinkedIn was the most widely used social media platform (51.6%). 38.8% of otolaryngologists had Facebook accounts with 11.9% of those 'public' accounts used for business purposes. Otolaryngologists with a research and authorship interest had the highest mean number of social media accounts (1.78) and were more likely to be associated with ResearchGate, LinkedIn and website ownership. Facial plastic surgeons averaged the second highest mean number of social media accounts per surgeon (1.71) and were most active on Facebook, Instagram and YouTube. There was a linear decline in the mean number of social media accounts per surgeon and rate of professional website ownership with increasing years in practice. CONCLUSION: Social media uptake amongst otolaryngologists appears consistent with colleagues in other surgical specialties. Otolaryngologists with fewer years in practice and specialty interests in facial plastic surgery and authorship and research are significantly more active on social media.
