A pilot study of performance enhancement coaching for newly appointed urology registrars

OBJECTIVES

To assess the feasibility of performance enhancement coaching (PEC) for newly appointed Urology registrars (ST3s), specifically: whether the concept appealed, and which areas beyond technical skills acquisition were felt to be most relevant or useful.

SUBJECTS AND METHODS

All delegates on the Urology Bootcamp 2023 were invited to take part in an online survey before and after a 2-hour PEC workshop, collecting: basic demographic data, performance challenges, and the important aspects to include in, and consider with, a coaching programme. The workshop was delivered by a surgeon with a professional coaching qualification, to groups of four delegates at a time over 4 days. Ten pre-defined areas were offered during the session.

RESULTS

On a scale of 1 (poor) to 10 (excellent), the 62 participants' overall health was reported as a median of 8/10 (physical) and 7/10 (mental). Anxiety during performance was the most common concern (63%) and was accompanied by a tremor in 55%. The next most popular concerns, with 19% of responses each, were: sleep, insufficient operative skill or expertise, and worry about relationships with trainers. The commonest topics discussed were 'the inner critic' (100%), 'autonomic modulation' (69%), 'not working, well' (13%) and 'optimising study' (6%). Seventy-seven per cent were unaware of PEC for practising surgeons. All respondents felt that they would benefit from PEC to some extent (80% ≥8/10 where 10/10 was 'very useful'), ideally at the ST3 level. Sixty-two percent of respondents said there should be a fee for trainees, whereas 38% thought it should be free and paid for by their training authorities.

CONCLUSION

The concept of PEC is acceptable to ST3 Urology trainees, with particular interest in techniques to mitigate negative self-talk and autonomic modulation techniques. Existing barriers to coaching for the surgical community would need to be addressed in designing an acceptable coaching programme.

The empty pelvis syndrome: a core data set from the PelvEx collaborative

BACKGROUND

Empty pelvis syndrome (EPS) is a significant source of morbidity following pelvic exenteration (PE), but is undefined. EPS outcome reporting and descriptors of radicality of PE are inconsistent; therefore, the best approaches for prevention are unknown. To facilitate future research into EPS, the aim of this study is to define a measurable core outcome set, core descriptor set and written definition for EPS. Consensus on strategies to mitigate EPS was also explored.

METHOD

Three-stage consensus methodology was used: longlisting with systematic review, healthcare professional event, patient engagement, and Delphi-piloting; shortlisting with two rounds of modified Delphi; and a confirmatory stage using a modified nominal group technique. This included a selection of measurement instruments, and iterative generation of a written EPS definition.

RESULTS

One hundred and three and 119 participants took part in the modified Delphi and consensus meetings, respectively. This encompassed international patient and healthcare professional representation with multidisciplinary input. Seventy statements were longlisted, seven core outcomes (bowel obstruction, enteroperineal fistula, chronic perineal sinus, infected pelvic collection, bowel obstruction, morbidity from reconstruction, re-intervention, and quality of life), and four core descriptors (magnitude of surgery, radiotherapy-induced damage, methods of reconstruction, and changes in volume of pelvic dead space) reached consensus-where applicable, measurement of these outcomes and descriptors was defined. A written definition for EPS was agreed.

CONCLUSIONS

EPS is an area of unmet research and clinical need. This study provides an agreed definition and core data set for EPS to facilitate further research.

Prostatic urethral lift for subjects in urinary retention (PULSAR): 12-Month results of a prospective controlled trial compared with real-world outcomes

Objective

To examine the safety and efficacy of prostatic urethral lift (PUL) in acute urinary retention (AUR) patients within a controlled (PULSAR) and real-world setting (Real-World Retrospective study).

Materials and methods

PULSAR was a 12-month prospective study of PUL in AUR patients (n = 51) performed at six centres in the United Kingdom; enrolled BPH patients aged ≥50 years, with prostate volume of ≤100 cc. AUR was defined as being catheter dependent with at least one prior failed trial without catheter (TWOC) while on an alpha-blocker. RWR consisted of 3226 consecutive PUL patients across 22 international sites treated between July 2017 and March 2020; 469 of whom were in urinary retention (RWRr), that is, catheter-dependent at the time of their procedure. Symptom response, uroflow and catheter independence rates were compared between PULSAR and RWRr subjects. A logistical regression model was constructed to evaluate patient baseline and dynamic factors predicting success after the procedure.

Results

Seventy-three percent of PULSAR subjects were catheter independent and free from surgical reintervention at 12 months post-PUL. Success was associated with higher voiding efficiency during the perioperative period. Slightly higher catheter-independent rates (80%) were seen in RWRr patients; variables that influenced success included age <70 years, lower baseline prostate-specific antigen (PSA), lower baseline post-void residual (PVR) and shorter pre-procedural catheter duration. Logistic regression of the combined PULSAR and RWRr retention groups revealed that procedural age <70 years and higher bladder voiding efficiency (BVE) were associated with success.

Conclusions

Lower baseline PSA and PVR, younger age and shorter pre-procedure catheter durations drove successful outcomes in AUR patients undergoing PUL. Post-PUL voiding efficiencies may help ascertain long-term response to treatment.

A Pilot Study Evaluating a Virtual Reality-Based Nontechnical Skills Training Application for Urology Trainees: Usability, Acceptability, and Impact

OBJECTIVE

This study aimed to develop and evaluate a virtual reality (VR)-based nontechnical skills (NTS) training application for urology trainees and assess its effectiveness in improving their skills and confidence.

DESIGN

A mixed-methods study was conducted to develop and evaluate a VR-based NTS training application for 32 urology trainees. The development process involved collaboration with 5 urology experts, 2 medical education specialists, and a human factors researcher. The study evaluated the application's usability, acceptability, and efficacy through 3 phases: scenario development with expert feedback integration, storyboarding and creation processes with facilitators and urology trainees, and a final evaluation by trainees.

SETTING

The data were collected during a 4-day urology boot camp in October 2022.

PARTICIPANTS

Thirty-two urology trainees participated in the study and completed 2 VR scenarios designed to enhance their NTS skills RESULTS: The System Usability Scale (SUS) showed a moderate usability score of 66. The Training Evaluation Inventory (TEI) and additional feedback demonstrated positive effects on trainees' learning and confidence in their NTS abilities. Most participants found the application easy to use, and effective and they expressed interest in using similar VR applications for other aspects of surgical training.

CONCLUSIONS

VR-based NTS training applications show potential for enhancing urology trainees' nontechnical skills. The integration of expert feedback and immersive technology offers a promising, accessible, and cost-effective solution to the challenges of delivering NTS training. Future research should explore the long-term impact of VR-based NTS training on trainees' performance and patient outcomes and consider incorporating advanced AI technologies for personalized and dynamic learning experiences.

Minimum standards of pelvic exenterative practice: PelvEx Collaborative guideline

This document outlines the important aspects of caring for patients who have been diagnosed with advanced pelvic cancer. It is primarily aimed at those who are establishing a service that adequately caters to this patient group. The relevant literature has been summarized and an attempt made to simplify the approach to management of these complex cases.

A Prospective Multi-Institutional Evaluation of Iatrogenic Urethral Catheterization Injuries

OBJECTIVES

To perform a multi-institutional investigation of incidence and outcomes of urethral trauma sustained during attempted catheterization.

PATIENTS & METHODS

A prospective, multi-center study was conducted over a designated 3-4 month period, incorporating seven academic hospitals across the UK and Ireland. Cases of urethral trauma arising from attempted catheterization were recorded. Variables included sites of injury, management strategies and short-term clinical outcomes. The catheterization injury rate was calculated based on the estimated total number of catheterizations occurring in each center per month. Anonymised data were collated, evaluated and described.

RESULTS

Sixty-six urethral catheterization injuries were identified (7 centers; mean 3.43 months). The mean injury rate was 6.2 ± 3.8 per 1000 catheterizations (3.18-14.42/1000). All injured patients were male, mean age 76.1 ± 13.1 years. Urethral catheterization injuries occurred in multiple hospital/community settings, most commonly Emergency Departments (36%) and medical/surgical wards (30%). Urological intervention was required in 94.7% (54/57), with suprapubic catheterization required in 12.3% (n = 7). More than half of patients (55.56%) were discharged with an urethral catheter, fully or partially attributable to the urethral catheter injury. At least one further healthcare encounter on account of the injury was required for 90% of patients post-discharge.

CONCLUSIONS

This is the largest study of its kind and confirms that iatrogenic urethral trauma is a recurring medical error seen universally across institutions, healthcare systems and countries. In addition, urethral catheter injury results in significant patient morbidity with a substantial financial burden to healthcare services. Future innovation to improve the safety of urinary catheterization is warranted.

Microbiomes of Urine and the Prostate Are Linked to Human Prostate Cancer Risk Groups

BACKGROUND

Bacteria play a suspected role in the development of several cancer types, and associations between the presence of particular bacteria and prostate cancer have been reported.

OBJECTIVE

To provide improved characterisation of the prostate and urine microbiome and to investigate the prognostic potential of the bacteria present.

DESIGN, SETTING, AND PARTICIPANTS

Microbiome profiles were interrogated in sample collections of patient urine (sediment microscopy: n = 318, 16S ribosomal amplicon sequencing: n = 46; and extracellular vesicle RNA-seq: n = 40) and cancer tissue (n = 204).

OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS

Microbiomes were assessed using anaerobic culture, population-level 16S analysis, RNA-seq, and whole genome DNA sequencing.

RESULTS AND LIMITATIONS

We demonstrate an association between the presence of bacteria in urine sediments and higher D'Amico risk prostate cancer (discovery, n = 215 patients, p < 0.001; validation, n = 103, p < 0.001, χ² test for trend). Characterisation of the bacterial community led to the (1) identification of four novel bacteria (Porphyromonas sp. nov., Varibaculum sp. nov., Peptoniphilus sp. nov., and Fenollaria sp. nov.) that were frequently found in patient urine, and (2) definition of a patient subgroup associated with metastasis development (p = 0.015, log-rank test). The presence of five specific anaerobic genera, which includes three of the novel isolates, was associated with cancer risk group, in urine sediment (p = 0.045, log-rank test), urine extracellular vesicles (p = 0.039), and cancer tissue (p = 0.035), with a meta-analysis hazard ratio for disease progression of 2.60 (95% confidence interval: 1.39-4.85; p = 0.003; Cox regression). A limitation is that functional links to cancer development are not yet established.

CONCLUSIONS

This study characterises prostate and urine microbiomes, and indicates that specific anaerobic bacteria genera have prognostic potential.

PATIENT SUMMARY

In this study, we investigated the presence of bacteria in patient urine and the prostate. We identified four novel bacteria and suggest a potential prognostic utility for the microbiome in prostate cancer.

Sepsis rates after template prostate biopsy with single-dose prophylactic antibiotic

Introduction

Urosepsis is a significant risk associated with prostate biopsy. Resistance of microorganisms to antibiotics is a challenging issue for clinicians in everyday practice. In the current study, we investigated the rates of sepsis and hospital admissions following transperineal (TP) prostate biopsies using a single dose of gentamicin.

Material and methods

Data for consecutive patients who underwent TP prostate biopsies (March 2019–March 2020) were included. Patients received a single-dose of prophylactic gentamicin 120 mg IV and had skin preparation with antiseptic povidone-iodine or chlorhexidine solution prior to the procedure. Patient’s electronic records were reviewed for rates of sepsis and readmission to hospital within 7 days following TP prostate biopsy.

Results

A total of 365 consecutive patients were included in the study. After exclusion of non-eligible patients, 280 patients were included in final analysis. The median age was 67 years (32–83), the median prostate-specific antigen (PSA) level was 8.5 ng/ml (0.2–58), and the median prostate size was 44 cc (10–188). Approximately 58% of patients had one or more comorbidities in the form of diabetes mellitus (DM), hypertension, asthma, chronic kidney disease, or ischemic heart disease. Adenocarcinoma was found in 71.7% of patients. None of the 280 patients developed sepsis. Urinary tract infection (UTI) occurred in 2.8% of patients with E.coli, none of them required hospital readmission.

Conclusions

Our single centre experience showed a 0% sepsis rate after TP prostate biopsy with single prophylactic dose of gentamicin. Future randomized controlled trials (RCTs) should explore the possibility of performing these procedures without antibiotic prophylaxis in order to reduce the unnecessary use of antibiotics.

Simultaneous pelvic exenteration and liver resection for primary rectal cancer with synchronous liver metastases: results from the PelvEx Collaborative

AIM

At presentation, 15-20% of patients with rectal cancer already have synchronous liver metastases. The aim of this study was to determine the surgical and survival outcomes in patients with advanced rectal cancer who underwent combined pelvic exenteration and liver (oligometastatic) resection.

METHOD

Data from 20 international institutions that performed simultaneous pelvic exenteration and liver resection between 2007 and 2017 were accumulated. Primarily, we examined perioperative outcomes, morbidity and mortality. We also assessed the impact that margin status had on survival.

RESULTS

Of 128 patients, 72 (56.2%) were men with a median age of 60 years [interquartile range (IQR) 15 years]. The median size of the liver oligometastatic deposits was 2 cm (IQR 1.8 cm). The median duration of surgery was 406 min (IQR 240 min), with a median blood loss of 1090 ml (IQR 2010 ml). A negative resection margin (R0 resection) was achieved in 73.5% of pelvic exenterations and 66.4% of liver resections. The 30-day mortality rate was 1.6%, and 32% of patients had a major postoperative complication. The 5-year overall survival for patients in whom an R0 resection of both primary and metastatic disease was achieved was 54.6% compared with 20% for those with an R1/R2 resection (P = 0.006).

CONCLUSION

Simultaneous pelvic exenteration and liver resection is feasible, with acceptable morbidity and mortality. Simultaneous resection should only be performed where an R0 resection of both pelvic and hepatic disease is anticipated.

Exercise-induced attenuation of treatment side-effects in patients with newly diagnosed prostate cancer beginning androgen-deprivation therapy: a randomised controlled trial

OBJECTIVES

(i) To assess whether exercise training attenuates the adverse effects of treatment in patients with newly diagnosed prostate cancer beginning androgen-deprivation therapy (ADT), and (ii) to examine whether exercise-induced improvements are sustained after the withdrawal of supervised exercise.

PATIENTS AND METHODS

In all, 50 patients with prostate cancer scheduled for ADT were randomised to an exercise group (n = 24) or a control group (n = 26). The exercise group completed 3 months of supervised aerobic and resistance exercise training (twice a week for 60 min), followed by 3 months of self-directed exercise. Outcomes were assessed at baseline, 3- and 6-months. The primary outcome was difference in fat mass at 3-months. Secondary outcomes included: fat-free mass, cardiopulmonary exercise testing variables, QRISK^® 2 (ClinRisk Ltd, Leeds, UK) score, anthropometry, blood-borne biomarkers, fatigue, and quality of life (QoL).

RESULTS

At 3-months, exercise training prevented adverse changes in peak O₂ uptake (1.9 mL/kg/min, P = 0.038), ventilatory threshold (1.7 mL/kg/min, P = 0.013), O₂ uptake efficiency slope (0.21, P = 0.005), and fatigue (between-group difference in Functional Assessment of Chronic Illness Therapy-Fatigue score of 4.5 points, P = 0.024) compared with controls. After the supervised exercise was withdrawn, the differences in cardiopulmonary fitness and fatigue were not sustained, but the exercise group showed significantly better QoL (Functional Assessment of Cancer Therapy-Prostate difference of 8.5 points, P = 0.034) and a reduced QRISK2 score (-2.9%, P = 0.041) compared to controls.

CONCLUSION

A short-term programme of supervised exercise in patients with prostate cancer beginning ADT results in sustained improvements in QoL and cardiovascular events risk profile.

The Success and Evolution of a Urological "Boot Camp" for Newly Appointed UK Urology Registrars: Incorporating Simulation, Nontechnical Skills and Assessment

BACKGROUND

Urological training has dramatically changed in recent years. Training durations are shorter and a drive toward consultant led care has reduced trainees experience. Within the UK, approximately 50 registrars annually embark on a 5-year Urology training programme, with variable levels of basic urological experience.

OBJECTIVE

To describe a simulation programme aimed at delivering the knowledge and skills necessary to safely and effectively start working as a registrar in Urology by intensive training with a 1:1 faculty to delegate ratio.

DESIGN, SETTING, AND PARTICIPANTS

Our course content mirrors the UK training syllabus for junior Urology registrars. We delivered 8 modules over a 4-day programme with a fifth day of assessments. Delegates level of urological knowledge, operative competency and confidence pre-, immediately post-training and at 3-months postcourse were assessed. Objective delegate and faculty feedback was also collected. Technical skills modules include; inguinoscrotal surgery, ureteroscopy, transurethral resection, urodynamics, and Botox administration as well as basic reconstructive and laparoscopic operative skills. "Nontechnical" skills included simulated ward round, out-patient, and emergency scenarios.

RESULTS

Feedback from delegates and faculty members has been overwhelmingly positive. We have used this feedback to tailor the content of the course for following years. An increased knowledge level (based on mean examination scores [precourse 55.5%, postcourse 70.1%]) and operative competency was observed in all skills assessed (transurethral resection of the prostate, transurethral resection of bladder tumor, Ureteroscopy, laparoscopic skills, and instrument assembly). Operative confidence was increased immediately and at 3-months postcourse.

CONCLUSIONS

Our "boot camp" course provides a realistic introduction and foundation to begin Urological practice. Being delivered at the beginning of the training scheme, prior to intensive patient exposure, registrars are in an optimum position to develop their newly acquired knowledge and skills to enhance training and intends to improve patient safety and satisfaction.

Patient perspectives of vigorous intensity aerobic interval exercise prehabilitation prior to radical cystectomy: a qualitative focus group study

PURPOSE

Preoperative cardiopulmonary fitness is increasingly being recognized as an important factor influencing postoperative recovery outcomes in cancer patients. The aim of this study was to explore patient perspectives of preoperative high intensity aerobic interval exercise before radical cystectomy.

MATERIALS AND METHODS

Focus groups involving a purposive convenience sample of patients with bladder cancer (N = 14; mean age ± SD: 72.3 ± 6.0 years) were undertaken in a hospital education department. Data were analyzed using Framework analysis.

RESULTS

Participants identified physical (e.g., fitness) psychological (e.g., preparing for their operation) and social (e.g., peer support) benefits of the program. Key motivational factors for engaging in exercise prehabiliation were identified as social support, previous exercise experience and objective measures of progression. The need for clear information from healthcare providers to ensure that patients are adequately prepared for sessions was highlighted.

CONCLUSIONS

This qualitative study provides new insights into the perspectives and experiences of patients with bladder cancer regarding participation in preoperative vigorous intensity aerobic exercise. The study yielded novel perceptions on the physical, psychological and social health benefits accruing from the exercise program and patient views on program design features, which are important for informing future interventions and implementation strategies.IMPLICATIONS FOR REHABILITATIONA preoperative high intensity aerobic interval exercise program before radical cystectomy provides physical, psychological and social benefits to individuals living with bladder cancer.Supervised exercise, objective improvement, and peer and family support all contribute to motivation to engage with preoperative high intensity aerobic interval exercise.Individuals may require support post-radical cystectomy in order to continue with exercise due to the uncertainty around this.

Abdominal wall ectopic testis torsion mimicking a Spigelian hernia in an adult

We report an unusual case of an ectopic testis identified in a 37-year-old man presenting with acute severe right iliac fossa pain and an irreducible mass. Initially diagnosed as a Spigelian hernia, computed tomography and ultrasonography identified the presence of an ectopic testis in the abdominal wall. Interparietal testicular ectopia is an extremely rare condition. We present and discuss the first case in the literature of an ectopic testis located between the internal and external oblique muscle layers of the anterior abdominal wall in an adult.

Self Management Activation Randomised Trial for Prostatitis (SMART-P): study protocol for a randomised controlled trial

BACKGROUND

Chronic prostatitis otherwise known as chronic pelvic pain syndrome is a common urological diagnosis that causes many men significant morbidity and has a detrimental effect on their quality of life. Standard treatment with antibiotics and simple analgesia are often ineffective and many patients are managed by the chronic pain services.Cognitive behavioural therapy has been shown to be helpful in the management of many chronic diseases and has recently been proposed as an effective treatment for chronic prostatitis. Furthermore, a self management programme administered to groups of men with lower urinary tract symptoms has been shown to be more effective than standard treatments including surgery.Therefore, we have developed a cognitive behavioural therapy programme specifically for men with chronic prostatitis. This novel treatment approach will be compared to conventional therapy in the pain clinic such as atypical analgesia and local anaesthetic injections in the context of a randomised controlled trial.

METHODS/DESIGN

Men will be recruited from general urology outpatient clinics following the exclusion of other diagnoses that could be responsible for their symptoms. Men will be randomised to attend either a self management healthcare and education programme or to pain clinic referral alone. The self management programme will be administered by a clinical psychologist to small groups of men over six consecutive weekly sessions each lasting two hours. Patients will be taught techniques of problem-solving and goal-setting and will learn coping mechanisms and how to modify catastrophic cognition.The primary outcome will be change from baseline in the National Institute of Health Chronic Prostatitis Symptom Index, a validated instrument for the assessment of men with chronic prostatitis. Secondary outcomes include generic quality of life scores and analgesic and drug usage. Outcomes will be assessed at 2, 6 and 12 months.

DISCUSSION

If this group administered self management programme is shown to be effective in the treatment of men with chronic prostatitis it may become the new standard of care for these patients. Furthermore, it may be adapted for use in women with interstitial cystitis, a condition which is analogous to chronic prostatitis in men.

Prospective evaluation of a novel one-stop testicular clinic

INTRODUCTION

In 2003, the waiting time for routine scrotal assessment approached 6 months in our hospital. The patients' diagnostic pathway was not uniform and involved several delays between general practitioner, radiologist and urologist. If malignancy was suspected, patients were seen and assessed within 2 weeks. However, it was possible for patients with unsuspected malignancy to have their diagnosis delayed.

PATIENTS AND METHODS

Funding was provided by the NHS Modernisation Agency's Action On Urology project. Men who were referred by their general practitioner (GP) with a testicular or scrotal condition would be reviewed in a one-stop joint sonographer and urology nurse specialist clinic provided entirely within the urology department with rapid open access. Data were prospectively collected for 2 years. Source of referral, suspected diagnosis, findings and outcome were recorded.

RESULTS

A total of 1017 patients attended the clinic over this period; of these, 203 (4%) were referred under the '2-week wait' criteria. Of patients attending the clinic, 79% were discharged to GP care, 8% were added to the waiting list for a surgical procedure and 20% were referred with 'testicular lump'. Eleven patients were suspected to have testicular tumour on ultrasound and proceeded to orchidectomy in this period. One patient (0.1%) was found to have an unsuspected seminoma. The waiting time for all scrotal ultrasound examinations has fallen from 22 to 2 weeks. The waiting times for intravenous urography and general ultrasound were also significantly reduced following the introduction of this service (P = 0.005).

CONCLUSIONS

The majority of patients passing through this clinic are the 'worried-well' with benign scrotal pathology. They can now be seen within 2 weeks regardless of whether their GP suspects testicular tumour. This reduces anxiety in this large group of patients freeing capacity elsewhere in the diagnostic imaging department.

Up-regulation of endothelial delta-like 4 expression correlates with vessel maturation in bladder cancer

PURPOSE

Angiogenesis and vascular endothelial growth factor (VEGF) expression are associated with a poor outcome in bladder cancer. To understand more about the mechanisms, we studied the role of delta-like 4 (DLL4), an endothelial-specific ligand of the Notch signaling pathway, in bladder cancer angiogenesis.

EXPERIMENTAL DESIGN

The expression of DLL4, CD34, and VEGF were studied in a cohort of 60 bladder tumors and 10 normal samples using quantitative PCR. In situ hybridization was used to study the pattern of DLL4 expression in 22 tumor and 9 normal samples. Serial sections were also stained for CD34 and alpha-smooth muscle actin (alpha-SMA) using conventional immunohistochemistry.

RESULTS

The expression of DLL4 was significantly up-regulated in superficial (P < 0.01) and invasive (P < 0.05) bladder cancers. DLL4 expression significantly correlated with CD34 (P < 0.001) and VEGF (P < 0.001) expression. The in situ hybridization studies showed that DLL4 was highly expressed within bladder tumor vasculature. Additionally, DLL4 expression significantly correlated with vessel maturation as judged by periendothelial cell expression of alpha-SMA, 98.7% of DLL4-positive tumor vessels coexpressed alpha-SMA, compared with 64.5% of DLL4-negative tumor vessels (P < 0.001). High DLL4 expression may have prognostic value in superficial and invasive bladder.

CONCLUSION

DLL4 expression is associated with vascular differentiation in bladder cancer; thus, targeting DLL4 may be a novel antiangiogenic therapy.

Facilities for chemical decontamination in accident and emergency departments in the United Kingdom

OBJECTIVE

To audit the facilities for chemical decontamination, with special reference to cyanide poisoning, in all major accident and emergency departments in the UK.

METHOD

A simple postal questionnaire was used to audit planning, premises, equipment, protection for staff, and stocks of specific antidotes to cyanide poisoning.

RESULTS

227 questionnaires from 261 departments (87%) were returned and used in the survey. Of the 227 departments who responded, 151 (66%) had a written plan; 168 (74%) departments had premises for decontamination; 55 (24%) were judged to have satisfactory premises; 146 (64%) departments had a shower or hose for decontamination; 60 (26%) departments had a decontamination trolley suitable for "stretcher" patients; 203 (89%) had some protective equipment for staff but only 77 (34%) had complete protection--that is, goggles, chemical resistant clothing, and breathing apparatus. In the authors' opinion only seven (3%) departments had satisfactory premises and equipment to treat "stretcher" patients and full protection for staff. A further 11 (5%) departments were equipped to manage ambulant patients at a similar level. Some 205 (90%) departments stocked one or more antidotes to cyanide and 77 (34%) stocked all four antidotes. Thirty four (15%) departments held all four antidotes to cyanide and had full protection for staff. Only five (2%) departments had satisfactory premises and equipment to treat "stretcher" patients, full protection for staff, and at least three of four antidotes.

CONCLUSIONS

Most departments had some equipment for chemical decontamination. However, there were major inconsistencies in the range of equipment held and these limited its usefulness. Only a small minority of departments was satisfactorily equipped to deal with a serious chemical incident.

A new technique for continent urinary diversion

Canine experimental surgery was used to investigate the feasibility of creating a new continent urinary reservoir. Remodelled ileum was used to fashion this reservoir like the Kock pouch, but without either of the intussuscepted nipple valves which it uses. Ureters were implanted directly into the wall of the reservoir using a nonrefluxing technique. Continence was obtained by plication of a short limb of intact ileum exiting from the reservoir through which intermittent catheterization was performed. Three of four animals which remained infection-free had good to excellent results. Reservoir infection in four additional animals was associated with failure due to ureteral obstruction. The advantages of this reservoir include the use of ileum to achieve a low-pressure reservoir, the absence of the complex nipple valves of the Kock pouch, and the absence of foreign bodies such as staples and artificial sphincters. While the followup in this study is recognized as relatively short-term, the successes seen in this difficult-to-use animal model suggest that further evaluation of this simplified procedure is warranted.
