Abstract

Objective: To document the recovery of vascular services in Europe following the first COVID-19 pandemic peak. Methods: An online structured vascular service survey with repeated data entry between 23 March and 9 August 2020 was carried out. Unit level data were collected using repeated questionnaires addressing modifications to vascular services during the first peak (March – May 2020, “period 1”), and then again between May and June (“period 2”) and June and July 2020 (“period 3”). The duration of each period was similar. From 2 June, as reductions in cases began to be reported, centres were first asked if they were in a region still affected by rising cases, or if they had passed the peak of the first wave. These centres were asked additional questions about adaptations made to their standard pathways to permit elective surgery to resume. Results: The impact of the pandemic continued to be felt well after countries’ first peak was thought to have passed in 2020. Aneurysm screening had not returned to normal in 21.7% of centres. Carotid surgery was still offered on a case by case basis in 33.8% of centres, and only 52.9% of centres had returned to their normal aneurysm threshold for surgery. Half of centres (49.4%) believed their management of lower limb ischaemia continued to be negatively affected by the pandemic. Reduced operating theatre capacity continued in 45.5% of centres. Twenty per cent of responding centres documented a backlog of at least 20 aortic repairs. At least one negative swab and 14 days of isolation were the most common strategies used for permitting safe elective surgery to recommence. Conclusion: Centres reported a broad return of services approaching pre-pandemic “normal” by July 2020. Many introduced protocols to manage peri-operative COVID-19 risk. Backlogs in cases were reported for all major vascular surgeries.

Abstract

The prediction of a difficult cholecystectomy has traditionally been based on certain pre-operative clinical and imaging factors. Most of the previous literature reported small patient cohorts and have not used an objective measure of operative difficulty. The aim of this study was to develop a pre-operative score to predict difficult cholecystectomy, as defined by a validated intra-operative difficulty grading scale. Two cohorts from prospectively maintained databases of patients who underwent laparoscopic cholecystectomy were analysed: the CholeS Study (8755 patients) and a single surgeon series (4089 patients). Factors potentially predictive of difficulty were correlated to the Nassar intra-operative difficulty scale. A multivariable binary logistic regression analysis was then used to identify factors that were independently associated with difficult laparoscopic cholecystectomy, defined as operative difficulty grades 3 to 5. The resulting model was then converted to a risk score, and validated on both internal and external datasets. Increasing age and ASA classification, male gender, diagnosis of CBD stone or cholecystitis, thick-walled gallbladders, CBD dilation, use of pre-operative ERCP and non-elective operations were found to be significant independent predictors of difficult cases. A risk score based on these factors returned an area under the ROC curve of 0.789 (95% CI 0.773–0.806, p

Abstract

This online structured survey has demonstrated the global impact of the COVID-19 pandemic on vascular services. The majority of centres have documented marked reductions in operating and services provided to vascular patients. In the months during recovery from the resource restrictions imposed during the pandemic peaks, there will be a significant vascular disease burden awaiting surgeons.

Abstract

A reliable system for grading operative difficulty of laparoscopic cholecystectomy would standardise description of findings and reporting of outcomes. The aim of this study was to validate a difficulty grading system (Nassar scale), testing its applicability and consistency in two large prospective datasets.Patient and disease-related variables and 30-day outcomes were identified in two prospective cholecystectomy databases: the multi-centre prospective cohort of 8820 patients from the recent CholeS Study and the single-surgeon series containing 4089 patients. Operative data and patient outcomes were correlated with Nassar operative difficultly scale, using Kendall's tau for dichotomous variables, or Jonckheere-Terpstra tests for continuous variables. A ROC curve analysis was performed, to quantify the predictive accuracy of the scale for each outcome, with continuous outcomes dichotomised, prior to analysis.A higher operative difficulty grade was consistently associated with worse outcomes for the patients in both the reference and CholeS cohorts. The median length of stay increased from 0 to 4 days, and the 30-day complication rate from 7.6 to 24.4% as the difficulty grade increased from 1 to 4/5 (both p 0.001). In the CholeS cohort, a higher difficulty grade was found to be most strongly associated with conversion to open and 30-day mortality (AUROC = 0.903, 0.822, respectively). On multivariable analysis, the Nassar operative difficultly scale was found to be a significant independent predictor of operative duration, conversion to open surgery, 30-day complications and 30-day reintervention (all p 0.001).We have shown that an operative difficulty scale can standardise the description of operative findings by multiple grades of surgeons to facilitate audit, training assessment and research. It provides a tool for reporting operative findings, disease severity and technical difficulty and can be utilised in future research to reliably compare outcomes according to case mix and intra-operative difficulty.

12. Consensus in Traditional Chinese Medical Diagnosis in Open Populations

Author

Abstract

© Copyright 2019, Mary Ann Liebert, Inc. Objectives: An acceptable level of diagnostic agreement is a prerequisite for consistent administration of treatment. It is critical for investigating effectiveness of different treatment approaches using multiple practitioners. To the best of our knowledge, no previous investigation of diagnostic consensus using open populations in Chinese medicine (CM) has been reported. Investigations restricted to individual medical conditions, such as have been usually studied, do not reveal any information as to what occurs in real world clinical settings. This knowledge gap led to the current study being conducted. Design/Location/Subjects/Interventions: Investigating diagnostic agreement specifically in Traditional Chinese Medicine (TCM) in an open population, two or three practitioners diagnosed 35 subjects at the University of Technology, Sydney (UTS), TCM clinic. The practitioners were restricted to a list of the 56 most frequently used TCM diagnoses at the UTS clinic. Up to three diagnostic patterns per subject could be selected, with nominated patterns scored between 1 and 5. Outcome measures: Agreement was determined with two criteria, both expressed as simple percentages: pattern and linearly weighted agreements. Results: The results showed that 23% of practitioners obtained pattern agreement, while 19% demonstrated weighted agreement. Conclusion: There appears to be very low diagnostic agreement between practitioners. This is an important finding. If unchallenged by further investigation, the recognition of such poor diagnostic consensus may lead to rejection of TCM theory before it has been adequately assessed. Diagnostic agreement must be improved so that future investigations into treatment effectiveness or mechanisms of action are made on a valid basis. Additionally, the current TCM diagnostic format must be altered to allow the application of chance-removed statistics or the calculation of a standard error with open popul

13. Appropriate Statistics for Determining Chance-Removed Interpractitioner Agreement

Abstract

© Copyright 2019, Mary Ann Liebert, Inc. Objectives: Fleiss' Kappa (FK) has been commonly, but incorrectly, employed as the "standard" for evaluating chance-removed inter-rater agreement with ordinal data. This practice may lead to misleading conclusions in inter-rater agreement research. An example is presented that demonstrates the conditions where FK produces inappropriate results, compared with Gwet's AC2, which is proposed as a more appropriate statistic. A novel format for recording a Chinese Medical (CM) diagnoses, called the Diagnostic System of Oriental Medicine (DSOM), was used to record and compare patient diagnostic data, which, unlike the contemporary CM diagnostic format, allows agreement by chance to be considered when evaluating patient data obtained with unrestricted diagnostic options available to diagnosticians. Design: Five CM practitioners diagnosed 42 subjects drawn from an open population. Subjects' diagnoses were recorded using the DSOM format. All the available data were initially used to evaluate agreement. Then, the subjects were sorted into three groups to demonstrate the effects of differing data marginality on the calculated chance-removed agreement. Outcome measures: Agreement between the practitioners for each subject was evaluated with linearly weighted simple agreement, FK and Gwet's AC2. Results and Conclusions: In all cases, overall agreement was much lower with FK than Gwet's AC2. Larger differences occurred when the data were more free marginal. Inter-rater agreement determined with FK statistics is unlikely to be correct unless it can be shown that the data from which agreement is determined are, in fact, fixed marginal. It follows that results obtained on agreement between practitioners with FK are probably incorrect. It is shown that inter-rater agreement evaluated with AC2 statistic is an appropriate measure when fixed marginal data are neither expected nor guaranteed. The AC2 statistic should be used as the standard statist

14. A Novel Approach to Describing Traditional Chinese Medical Patterns: The 'traditional Chinese Medical Diagnostic Descriptor'

Author

Popplewell, M, Reizes, J, Zaslawski, C, Popplewell, M, Reizes, J, and Zaslawski, C

Abstract

© Copyright 2019, Mary Ann Liebert, Inc. Objectives: In the first of a series of three articles by the present authors, diagnostic agreement between Traditional Chinese Medicine (TCM) practitioners was found to be low. This was the first time that TCM diagnoses had been evaluated with an open population of patients and this result is a cause of concern. In the second article, incorrect statistics were shown to have often been used to calculate chance-removed inter-rater agreement, and appropriate statistics such as Gwet's Agreement Coefficient 2 (AC2) was recommended for future studies. In this, the third article, a novel approach to recording TCM diagnostic patterns, the Traditional Chinese Medical Diagnostic Descriptor (TCMDD), is presented that allows chance-removed agreement calculation. An example of mapping TCM diagnostic patterns to the TCMDD format is given and diagnostic agreement is evaluated. Design, Settings, Subjects: The same 35 subjects used to report agreement in our first article were also diagnosed by additional practitioners using the TCMDD format during the same experimental sessions at the University of Technology, Sydney Clinic. TCM diagnoses from the first article were also mapped to the TCMDD format. Outcome measures: Linearly weighted simple agreement and the AC2 statistic were utilized and all results compared. Results: Linearly weighted simple agreement using the TCMDD and TCM mapped to TCMDD format averaged 0.80 ± 0.02 compared with 0.19 for TCM. TCMDD and TCM mapped to TCMDD chance-removed agreement, as calculated with AC2, ranged between 0.67 and 0.73 ± 0.03. Conclusions: The TCMDD allows the essence of diagnoses expressed by TCM practitioners to be appropriately compared. This was confirmed by the TCM mapped to TCMDD results. In both cases, simple agreement was significantly greater than that obtained with the TCM format. Chance-removed statistics and error estimates can be reliably calculated with the AC2 and the TCMDD in open populat

Abstract

Background The ability to accurately predict operative duration has the potential to optimise theatre efficiency and utilisation, thus reducing costs and increasing staff and patient satisfaction. With laparoscopic cholecystectomy being one of the most commonly performed procedures worldwide, a tool to predict operative duration could be extremely beneficial to healthcare organisations. Methods Data collected from the CholeS study on patients undergoing cholecystectomy in UK and Irish hospitals between 04/2014 and 05/2014 were used to study operative duration. A multivariable binary logistic regression model was produced in order to identify significant independent predictors of long (> 90 min) operations. The resulting model was converted to a risk score, which was subsequently validated on second cohort of patients using ROC curves. Results After exclusions, data were available for 7227 patients in the derivation (CholeS) cohort. The median operative duration was 60 min (interquartile range 45–85), with 17.7% of operations lasting longer than 90 min. Ten factors were found to be significant independent predictors of operative durations > 90 min, including ASA, age, previous surgical admissions, BMI, gallbladder wall thickness and CBD diameter. A risk score was then produced from these factors, and applied to a cohort of 2405 patients from a tertiary centre for external validation. This returned an area under the ROC curve of 0.708 (SE = 0.013, p 90 min increasing more than eightfold from 5.1 to 41.8% in the extremes of the score. Conclusion The scoring tool produced in this study was found to be significantly predictive of long operative durations on validation in an external cohort. As such, the tool may have the potential to enable organisations to better organise theatre lists and deliver greater efficiencies in care.

Abstract

Background The aim was to describe the management of benign gallbladder disease and identify characteristics associated with all-cause 30-day readmissions and complications in a prospective population-based cohort. Methods Data were collected on consecutive patients undergoing cholecystectomy in acute UK and Irish hospitals between 1 March and 1 May 2014. Potential explanatory variables influencing all-cause 30-day readmissions and complications were analysed by means of multilevel, multivariable logistic regression modelling using a two-level hierarchical structure with patients (level 1) nested within hospitals (level 2). Results Data were collected on 8909 patients undergoing cholecystectomy from 167 hospitals. Some 1451 cholecystectomies (16·3 per cent) were performed as an emergency, 4165 (46·8 per cent) as elective operations, and 3293 patients (37·0 per cent) had had at least one previous emergency admission, but had surgery on a delayed basis. The readmission and complication rates at 30 days were 7·1 per cent (633 of 8909) and 10·8 per cent (962 of 8909) respectively. Both readmissions and complications were independently associated with increasing ASA fitness grade, duration of surgery, and increasing numbers of emergency admissions with gallbladder disease before cholecystectomy. No identifiable hospital characteristics were linked to readmissions and complications. Conclusion Readmissions and complications following cholecystectomy are common and associated with patient and disease characteristics.

Abstract

Background The aims of this prospective population-based cohort study were to identify the patient and hospital characteristics associated with emergency cholecystectomy, and the influences of these in determining variations between hospitals. Methods Data were collected for consecutive patients undergoing cholecystectomy in acute UK and Irish hospitals between 1 March and 1 May 2014. Potential explanatory variables influencing the performance of emergency cholecystectomy were analysed by means of multilevel, multivariable logistic regression modelling using a two-level hierarchical structure with patients (level 1) nested within hospitals (level 2). Results Data were collected on 4744 cholecystectomies from 165 hospitals. Increasing age, lower ASA fitness grade, biliary colic, the need for further imaging (magnetic retrograde cholangiopancreatography), endoscopic interventions (endoscopic retrograde cholangiopancreatography) and admission to a non-biliary centre significantly reduced the likelihood of an emergency cholecystectomy being performed. The multilevel model was used to calculate the probability of receiving an emergency cholecystectomy for a woman aged 40 years or over with an ASA grade of I or II and a BMI of at least 25·0 kg/m2, who presented with acute cholecystitis with an ultrasound scan showing a thick-walled gallbladder and a normal common bile duct. The mean predicted probability of receiving an emergency cholecystectomy was 0·52 (95 per cent c.i. 0·45 to 0·57). The predicted probabilities ranged from 0·02 to 0·95 across the 165 hospitals, demonstrating significant variation between hospitals. Conclusion Patients with similar characteristics presenting to different hospitals with acute gallbladder pathology do not receive comparable care.

Abstract

OBJECTIVE To document the recovery of vascular services in Europe following the first COVID-19 pandemic peak. METHODS An online structured vascular service survey with repeated data entry between 23 March and 9 August 2020 was carried out. Unit level data were collected using repeated questionnaires addressing modifications to vascular services during the first peak (March - May 2020, "period 1"), and then again between May and June ("period 2") and June and July 2020 ("period 3"). The duration of each period was similar. From 2 June, as reductions in cases began to be reported, centres were first asked if they were in a region still affected by rising cases, or if they had passed the peak of the first wave. These centres were asked additional questions about adaptations made to their standard pathways to permit elective surgery to resume. RESULTS The impact of the pandemic continued to be felt well after countries' first peak was thought to have passed in 2020. Aneurysm screening had not returned to normal in 21.7% of centres. Carotid surgery was still offered on a case by case basis in 33.8% of centres, and only 52.9% of centres had returned to their normal aneurysm threshold for surgery. Half of centres (49.4%) believed their management of lower limb ischaemia continued to be negatively affected by the pandemic. Reduced operating theatre capacity continued in 45.5% of centres. Twenty per cent of responding centres documented a backlog of at least 20 aortic repairs. At least one negative swab and 14 days of isolation were the most common strategies used for permitting safe elective surgery to recommence. CONCLUSION Centres reported a broad return of services approaching pre-pandemic "normal" by July 2020. Many introduced protocols to manage peri-operative COVID-19 risk. Backlogs in cases were reported for all major vascular surgeries.

Abstract

Background: Chronic limb-threatening ischaemia with ischaemic pain and/or tissue loss., Objective: To examine the clinical and cost-effectiveness of a vein bypass-first compared to a best endovascular treatment-first revascularisation strategy in preventing major amputation or death., Design: Superiority, open, pragmatic, multicentre, phase III randomised trial., Setting: Thirty-nine vascular surgery units in the United Kingdom, and one each in Sweden and Denmark., Participants: Patients with chronic limb-threatening ischaemia due to atherosclerotic peripheral arterial disease who required an infra-popliteal revascularisation, with or without an additional more proximal infra-inguinal revascularisation procedure, to restore limb perfusion., Interventions: A vein bypass-first or a best endovascular treatment-first infra-popliteal, with or without an additional more proximal infra-inguinal revascularisation strategy., Main Outcome Measures: The primary outcome was amputation-free survival. Secondary outcomes included overall survival, major amputation, further revascularisation interventions, major adverse limb event, health-related quality of life and serious adverse events., Methods: Participants were randomised to a vein bypass-first or a best endovascular treatment-first revascularisation strategy. The original sample size of 600 participants (247 events) was based on a hazard ratio of 0.66 with amputation-free survival rates of 0.72, 0.62, 0.53, 0.47 and 0.35 in years 1-5 in the best endovascular treatment-first group with 90% power and alpha at p  = 0.05. The sample size was revised to an event-based approach as a result of increased follow-up time due to slower than anticipated recruitment rates. Participants were followed up for a minimum of 2 years. A cost-effectiveness analysis was employed to estimate differences in total hospital costs and amputation-free survival between the groups. Additionally, a cost-utility analysis was carried out and the total cost and quality-adjusted life-years, 2 and 3 years after randomisation were used., Results: Between 22 July 2014 and 30 November 2020, 345 participants were randomised, 172 to vein bypass-first and 173 to best endovascular treatment-first. Non-amputation-free survival occurred in 108 (63%) of 172 patients in the vein bypass-first group and 92 (53%) of 173 patients in the best endovascular treatment-first group [adjusted hazard ratio 1.35 (95% confidence interval 1.02 to 1.80); p  = 0.037]. Ninety-one (53%) of 172 patients in the vein bypass-first group and 77 (45%) of 173 patients in the best endovascular treatment-first group died [adjusted hazard ratio 1.37 (95% confidence interval 1.00 to 1.87)]. Over follow-up, the economic evaluation discounted results showed that best endovascular treatment-first was associated with £1690 less hospital costs compared to vein bypass-first. The cost utility analysis showed that compared to vein bypass-first, best endovascular treatment-first was associated with £224 and £2233 less discounted hospital costs and 0.016 and 0.085 discounted quality-adjusted life-year gain after 2 and 3 years from randomisation., Limitations: Recruiting patients to the Bypass versus Angioplasty in Severe Ischaemia of the Leg Trial-2 trial was difficult and the target number of events was not achieved., Conclusions: A best endovascular treatment-first revascularisation strategy was associated with better amputation-free survival, which was largely driven by fewer deaths. Overall, the economic evaluation results suggest that best endovascular treatment-first dominates vein bypass-first in the cost-effectiveness analysis and cost-utility analysis as it was less costly and more effective than a vein bypass-first strategy., Future Work: The Bypass versus Angioplasty in Severe Ischaemia of the Leg Trial-2 investigators have a data sharing agreement with the BEst Surgical Therapy in patients with Chronic Limb threatening Ischaemia investigators. One output of this collaboration will be an individual patient data meta-analysis., Study Registration: Current Controlled Trials ISRCTN27728689., Funding: This award was funded by the National Institute for Health and Care Research (NIHR) Health Technology Assessment programme (NIHR award ref: 12/35/45) and is published in full in Health Technology Assessment ; Vol. 28, No. 65.

Abstract

Objective: The Bypass versus Angioplasty in Severe Ischaemia of the Leg (BASIL)-2 trial enrolled participants with chronic limb threatening ischaemia who required an infrapopliteal, with or without a femoropopliteal, revascularisation procedure to restore limb perfusion. Participants randomised to a vein bypass (VB) first revascularisation strategy were over one third more likely than those randomised to a best endovascular treatment (BET) first revascularisation strategy to die from any cause during a median follow up of 40.0 (interquartile range 20.9, 60.6) months. The aim of the present study was to describe the timing and causes of death in BASIL-2 as a first step towards trying to better understand why randomisation to a VB first revascularisation strategy was associated with this excess mortality., Methods: A 10 person international panel comprising vascular and endovascular surgeons as well as vascular interventional radiologists, who had all been principal investigators in BASIL-2, took part in a modified Delphi consensus exercise to adjudicate the primary cause of death and, in particular, whether the cause was primarily cardiac or non-cardiac., Results: In 151 of 168 deaths (89.9%), the Delphi panel achieved a consensus regarding the cause of death being probably cardiac or non-cardiac. In the BET group, 16 of 77 deaths (21%) were classified as probably cardiac compared with 32 of 91 (35%) in the VB group (unadjusted subdistribution hazard ratio 2.16, 95% confidence interval [CI] 1.20 - 3.87; unadjusted cause specific hazard ratio 2.15, 95% CI 1.19 - 3.90). At the point of randomisation, 64 of 344 (18.6%), 40 of 342 (11.7%), and 37 of 344 (10.8%) participants had a previous myocardial infarction (MI), percutaneous coronary intervention (PCI), and coronary artery bypass graft (CABG), respectively. There was no evidence of varying treatment effects for cause of death in subgroup analyses of previous PCI, CABG, or MI., Conclusion: The excess mortality observed in the VB first revascularisation strategy group in BASIL-2 was largely due to deaths that were adjudicated by the Delphi panel as probably primarily cardiac. These excess cardiac deaths were observed throughout follow up and there was no evidence of non-proportional hazards. Further work is ongoing to try to better understand the reasons for these findings., (Copyright © 2024 The Authors. Published by Elsevier B.V. All rights reserved.)

Abstract

Surgical site infections (SSIs) following major lower limb amputation (MLLA) in vascular patients are a major source of morbidity. The objective of this systematic review was to determine the incidence of SSI following MLLA in vascular patients. This review was prospectively registered with the International Prospective Register of Systematic Reviews (CRD42023460645). Databases were searched without date restriction using a pre-defined search strategy. The search identified 1427 articles. Four RCTs and 21 observational studies, reporting on 50 370 MLLAs, were included. Overall SSI incidence per MLLA incision was 7.2% (3628/50370). The incidence of SSI in patients undergoing through-knee amputation (12.9%) and below-knee amputation (7.5%) was higher than the incidence of SSI in patients undergoing above-knee amputation, (3.9%), p < 0.001. The incidence of SSI in studies focusing on patients with peripheral arterial disease (PAD), diabetes or including patients with both was 8.9%, 6.8% and 7.2%, respectively. SSI is a common complication following MLLA in vascular patients. There is a higher incidence of SSI associated with more distal amputation levels. The reported SSI incidence is similar between patients with underlying PAD and diabetes. Further studies are needed to understand the exact incidence of SSI in vascular patients and the factors which influence this., (© 2024 The Author(s).

Abstract

Background: Chronic limb-threatening ischaemia is the severest manifestation of peripheral arterial disease and presents with ischaemic pain at rest or tissue loss (ulceration, gangrene, or both), or both. We compared the effectiveness of a vein bypass first with a best endovascular treatment first revascularisation strategy in terms of preventing major amputation and death in patients with chronic limb threatening ischaemia who required an infra-popliteal, with or without an additional more proximal infra-inguinal, revascularisation procedure to restore limb perfusion., Methods: Bypass versus Angioplasty for Severe Ischaemia of the Leg (BASIL)-2 was an open-label, pragmatic, multicentre, phase 3, randomised trial done at 41 vascular surgery units in the UK (n=39), Sweden (n=1), and Denmark (n=1). Eligible patients were those who presented to hospital-based vascular surgery units with chronic limb-threatening ischaemia due to atherosclerotic disease and who required an infra-popliteal, with or without an additional more proximal infra-inguinal, revascularisation procedure to restore limb perfusion. Participants were randomly assigned (1:1) to receive either vein bypass (vein bypass group) or best endovascular treatment (best endovascular treatment group) as their first revascularisation procedure through a secure online randomisation system. Participants were excluded if they had ischaemic pain or tissue loss considered not to be primarily due to atherosclerotic peripheral artery disease. Most vein bypasses used the great saphenous vein and originated from the common or superficial femoral arteries. Most endovascular interventions comprised plain balloon angioplasty with selective use of plain or drug eluting stents. Participants were followed up for a minimum of 2 years. Data were collected locally at participating centres. In England, Wales, and Sweden, centralised databases were used to collect information on amputations and deaths. Data were analysed centrally at the Birmingham Clinical Trials Unit. The primary outcome was amputation-free survival defined as time to first major (above the ankle) amputation or death from any cause measured in the intention-to-treat population. Safety was assessed by monitoring serious adverse events up to 30-days after first revascularisation. The trial is registered with the ISRCTN registry, ISRCTN27728689., Findings: Between July 22, 2014, and Nov 30, 2020, 345 participants (65 [19%] women and 280 [81%] men; median age 72·5 years [62·7-79·3]) with chronic limb-threatening ischaemia were enrolled in the trial and randomly assigned: 172 (50%) to the vein bypass group and 173 (50%) to the best endovascular treatment group. Major amputation or death occurred in 108 (63%) of 172 patients in the vein bypass group and 92 (53%) of 173 patients in the best endovascular treatment group (adjusted hazard ratio [HR] 1·35 [95% CI 1·02-1·80]; p=0·037). 91 (53%) of 172 patients in the vein bypass group and 77 (45%) of 173 patients in the best endovascular treatment group died (adjusted HR 1·37 [95% CI 1·00-1·87]). In both groups the most common causes of morbidity and death, including that occurring within 30 days of their first revascularisation, were cardiovascular (61 deaths in the vein bypass group and 49 in the best endovascular treatment group) and respiratory events (25 deaths in the vein bypass group and 23 in the best endovascular treatment group; number of cardiovascular and respiratory deaths were not mutually exclusive)., Interpretation: In the BASIL-2 trial, a best endovascular treatment first revascularisation strategy was associated with a better amputation-free survival, which was largely driven by fewer deaths in the best endovascular treatment group. These data suggest that more patients with chronic limb-threatening ischaemia who required an infra-popliteal, with or without an additional more proximal infra-inguinal, revascularisation procedure to restore limb perfusion should be considered for a best endovascular treatment first revascularisation strategy., Funding: UK National Institute of Health Research Health Technology Programme., Competing Interests: Declaration of interests AWB reports salary part paid by a National Institute for Health (NIHR) and Care Research Health Technology Assessment (HTA) BASIL-2 grant; payment expert advice and testimony from NHS Resolution, His Majesty's Coroners, National Crime Agency, UK, Scotland, Wales, and Northern Ireland Governments, and various law firms, outside of the submitted work; and payment to his institution and personal honoraria for committee work from NIHR HTA and NICE.

Abstract

Background: The Global Limb Anatomic Staging System (GLASS) is a new method of quantifying the anatomic severity of infrainguinal disease in patients with chronic limb-threatening ischemia. However, because GLASS has undergone limited validation, its value as an aid to shared decision-making regarding the choice of revascularization strategy remains incompletely defined. Here we report the relationship between GLASS and outcomes in a contemporary series comprising all 309 patients who underwent an attempt at femoropopliteal and/or infrapopiteal endovascular therapy for chronic limb-threatening ischemia in our unit between 2009 and 2014., Methods: Baseline patient characteristics and outcome data including immediate technical success (ITS), amputation-free survival (AFS), overall survival, limb salvage, freedom from reintervention (FF-R), and freedom from major adverse limb events (FF-MALE) were obtained from hospital databases. GLASS grades and stage were obtained from pre-endovascular therapy angiographic imaging. Outcome data were censored on May 31, 2017., Results: Baseline patient characteristics were similar across different GLASS femoropopliteal and IP grades and overall limb stages. Worsening GLASS stage was associated with a significant reduction in ITS (97.5% vs 91.5% vs 84.0%; P = .029). At 72 months FF-R (hazard ratio, 2.00; 95% confidence interval, 1.11-3.57; P = .020) and FF-MALE (hazard ratio, 1.76, 95% confidence interval, 1.10-2.81; P = .019) were significant worse in GLASS stage 3 than in stage 2 limbs., Conclusions: In our study, there were significant differences in ITS, FF-R and FF-MALE between limbs with GLASS stage 2 and 3 disease. However, further GLASS refinement seems likely to be required if its usefulness in everyday clinical practice as an aid to shared decision-making regarding the choice of revascularization strategy is to be maximized., (Copyright © 2022 Society for Vascular Surgery.

Abstract

Introduction: Acute scrotal pain is a common paediatric surgical emergency. Assessment and timely exploration are required to rule out testicular torsion (TT) and prevent unnecessary morbidity., Methods: A retrospective observational cohort study was carried out at two district general hospitals in the UK for boys aged ≤16 years presenting with acute scrotal pain between January 2014 and October 2017 managed by adult general surgery (AGS) at one hospital and adult urology (AU) at the other., Results: Some 565 patients were eligible for inclusion ( n =364 AGS, n =201 AU). A higher proportion of patients underwent surgical exploration at AGS compared with AU (277/346 (80.1%) vs 96/201 (47.8%); p <0.001). Of those who underwent exploration, 101/373 (27.1%) had TT, of whom 25/101 (24.8%) underwent orchidectomy and 125/373 (33.5%) had torted testicular appendage. There was no statistically significant difference in rates of orchidectomy between AGS (19/68, 27.9%) and AU (6/33, 18.2%) with testicular salvage rates of 72.1% and 81.8%, respectively ( p =0.334). Patients were twice as likely to be readmitted at AGS as at AU (28/346 (8.1%) vs 8/201 (4.0%); p =0.073)., Conclusion: Although intraoperative findings were similar between adult general surgeons and urologists, there were significant differences in surgical management, with a higher rate of surgical exploration by general surgeons. Testicular salvage and 30-day postoperative morbidity rates at both institutions were acceptable but the readmission rate was high at 6.6%. It is not known why there is a heterogeneity in management of acute scrotal pain between specialist centres, and further prospective investigations are warranted.

Abstract

Background: Since the turn of the millennium, there has been a worldwide trend towards an endovascular-first strategy where possible revascularization strategy for chronic limb-threatening ischemia. There is concern that this may be inappropriate and can result in net patient harm. The aim of this study, therefore, is to compare important clinical outcomes following femoropopliteal plain balloon angioplasty (FP-PBA), with selective use of bare metal stents (BMSs), in a contemporary series (CS) of patients treated in our unit between 2009 and 2014 with those observed following FP-PBA ± BMS in the United Kingdom National Institute of Health Research Health Technology Assessment-funded Bypass vs Angioplasty in Severe Ischaemia of the Leg (BASIL-1 [B1]) trial (treated 1999-2004)., Methods: Baseline and clinical outcome data (amputation-free survival [AFS], overall survival [OS], limb salvage, freedom from reintervention, and freedom from major adverse limb events) were obtained from prospectively gathered hospital data and B1 trial case record forms., Results: There were 237 CS and 218 B1 patients. CS patients were older (77 vs 73 years; P = .0002). B1 patients were more likely to be current smokers, less likely to be on best medical therapy, and underwent more extensive endovascular interventions. CS had more hospital admissions (4 vs 2; P < .0001) before they reached their primary endpoint (AFS). Immediate technical success was nonsignificantly higher in the CS patients (87% vs 83%; P = .2). BMS were used in 20 CS (8%) and 2 B1 (1%) patients (P = .0002). AFS (hazard ratio, 0.64; 95% confidence interval, 0.49-0.82; P = .0005) and OS (hazard ratio, 0.58; 95% confidence interval, 0.44-0.76; P = .0001) were significantly worse in the CS cohort. There was no significant difference in limb salvage, freedom from reintervention, or freedom from major adverse limb events., Conclusions: Patients with chronic limb-threatening ischemia managed in our unit (2009-2014) by means of a FP-PBA ± BMS first (where possible) revascularization strategy experienced significantly worse AFS and OS than patients treated with FP-PBA ± BMS in the B1 trial 10 years earlier (1999-2004)., (Copyright © 2021 Society for Vascular Surgery.

Abstract

Objective: The Global Vascular Guideline on chronic limb threatening ischaemia (CLTI) has introduced the Global Limb Anatomic Staging System (GLASS) as a new angiographic scoring system. However, the relationship between GLASS and outcomes following revascularisation has not previously been studied., Methods: Using pre-intervention angiograms the relationship between GLASS and immediate technical failure (ITF), amputation free survival (AFS), limb salvage (LS), overall survival (OS), and freedom from major adverse limb events (FF-MALE) was examined in 377 patients undergoing endovascular therapy (EVT, n = 213) or bypass surgery (BS, n = 164) in the Bypass versus Angioplasty in Severe Ischaemia of the Leg (BASIL)-1 trial (randomised 1999-2004)., Results: There was no significant difference in GLASS between cohorts. There was a significant relationship between ITF and GLASS in EVT (I 14%, II 15%, III 28%, p = .049). GLASS was significantly related to AFS (hazard ratio [HR], 1.37; 95% CI 1.01-1.85; p = .042), LS (HR 1.96; 95 % CI 1.12-3.43; p = .018), and FF-MALE (HR 1.49; 95% CI 1.04-1.87; p = .028) in the EVT cohort. In BS patients, there was no relationship between GLASS and these outcomes. FF-MALE was significantly worse after EVT than BS in GLASS II (p = .038) and III (p = .001). Among the subgroup of patients with femoropopliteal (FP) disease (BS, n = 109 or EVT, n = 159), FF-MALE was significantly higher after BS than EVT (p < .001). The superiority of BS over EVT with increasing GLASS FP grade was greater in the analysis of patients using vein grafts., Conclusion: In the BASIL-1 cohort, GLASS is associated with outcomes following EVT but not BS. Although further validation in contemporary CLTI cohorts is required, GLASS seems likely be useful in shared decision making and for stratifying patients in future trials., (Copyright © 2020 European Society for Vascular Surgery.

Abstract

Objectives: Venous thromboembolism is a potentially fatal complication of superficial endovenous treatment. Proper risk assessment and thromboprophylaxis could mitigate this hazard; however, there are currently no evidence-based or consensus guidelines. This study surveyed UK and Republic of Ireland vascular consultants to determine areas of consensus., Methods: A 32-item survey was sent to vascular consultants via the Vascular and Endovascular Research Network (phase 1). These results generated 10 consensus statements which were redistributed (phase 2). 'Good' and 'very good' consensus were defined as endorsement/rejection of statements by >67% and >85% of respondents, respectively., Results: Forty-two consultants completed phase 1. This generated seven statements regarding risk factors mandating peri-procedural pharmacoprophylaxis and three statements regarding specific pharmacoprophylaxis regimes. Forty-seven consultants completed phase 2. Regarding venous thromboembolism risk factors mandating pharmacoprophylaxis, 'good' and 'very good' consensus was achieved for 5/7 and 2/7 statements, respectively. Regarding specific regimens, 'very good' consensus was achieved for 3/3 statements., Conclusions: The main findings from this study were that there was 'good' or 'very good' consensus that patients with any of the seven surveyed risk factors should be given pharmacoprophylaxis with low-molecular-weight heparin. High-risk patients should receive one to two weeks of pharmacoprophylaxis rather than a single dose.

Abstract

Objectives: In the first of a series of three articles by the present authors, diagnostic agreement between Traditional Chinese Medicine (TCM) practitioners was found to be low. This was the first time that TCM diagnoses had been evaluated with an open population of patients and this result is a cause of concern. In the second article, incorrect statistics were shown to have often been used to calculate chance-removed inter-rater agreement, and appropriate statistics such as Gwet's Agreement Coefficient 2 (AC2) was recommended for future studies. In this, the third article, a novel approach to recording TCM diagnostic patterns, the Traditional Chinese Medical Diagnostic Descriptor (TCMDD), is presented that allows chance-removed agreement calculation. An example of mapping TCM diagnostic patterns to the TCMDD format is given and diagnostic agreement is evaluated. Design, Settings, Subjects: The same 35 subjects used to report agreement in our first article were also diagnosed by additional practitioners using the TCMDD format during the same experimental sessions at the University of Technology, Sydney Clinic. TCM diagnoses from the first article were also mapped to the TCMDD format. Outcome measures: Linearly weighted simple agreement and the AC2 statistic were utilized and all results compared. Results: Linearly weighted simple agreement using the TCMDD and TCM mapped to TCMDD format averaged 0.80 ± 0.02 compared with 0.19 for TCM. TCMDD and TCM mapped to TCMDD chance-removed agreement, as calculated with AC2, ranged between 0.67 and 0.73 ± 0.03. Conclusions: The TCMDD allows the essence of diagnoses expressed by TCM practitioners to be appropriately compared. This was confirmed by the TCM mapped to TCMDD results. In both cases, simple agreement was significantly greater than that obtained with the TCM format. Chance-removed statistics and error estimates can be reliably calculated with the AC2 and the TCMDD in open populations.

Abstract

Objectives: Fleiss' Kappa (FK) has been commonly, but incorrectly, employed as the "standard" for evaluating chance-removed inter-rater agreement with ordinal data. This practice may lead to misleading conclusions in inter-rater agreement research. An example is presented that demonstrates the conditions where FK produces inappropriate results, compared with Gwet's AC2, which is proposed as a more appropriate statistic. A novel format for recording a Chinese Medical (CM) diagnoses, called the Diagnostic System of Oriental Medicine (DSOM), was used to record and compare patient diagnostic data, which, unlike the contemporary CM diagnostic format, allows agreement by chance to be considered when evaluating patient data obtained with unrestricted diagnostic options available to diagnosticians. Design: Five CM practitioners diagnosed 42 subjects drawn from an open population. Subjects' diagnoses were recorded using the DSOM format. All the available data were initially used to evaluate agreement. Then, the subjects were sorted into three groups to demonstrate the effects of differing data marginality on the calculated chance-removed agreement. Outcome measures: Agreement between the practitioners for each subject was evaluated with linearly weighted simple agreement, FK and Gwet's AC2. Results and Conclusions: In all cases, overall agreement was much lower with FK than Gwet's AC2. Larger differences occurred when the data were more free marginal. Inter-rater agreement determined with FK statistics is unlikely to be correct unless it can be shown that the data from which agreement is determined are, in fact, fixed marginal. It follows that results obtained on agreement between practitioners with FK are probably incorrect. It is shown that inter-rater agreement evaluated with AC2 statistic is an appropriate measure when fixed marginal data are neither expected nor guaranteed. The AC2 statistic should be used as the standard statistical approach for determining agreement between practitioners.

Abstract

Objectives: An acceptable level of diagnostic agreement is a prerequisite for consistent administration of treatment. It is critical for investigating effectiveness of different treatment approaches using multiple practitioners. To the best of our knowledge, no previous investigation of diagnostic consensus using open populations in Chinese medicine (CM) has been reported. Investigations restricted to individual medical conditions, such as have been usually studied, do not reveal any information as to what occurs in real world clinical settings. This knowledge gap led to the current study being conducted. Design/Location/Subjects/Interventions: Investigating diagnostic agreement specifically in Traditional Chinese Medicine (TCM) in an open population, two or three practitioners diagnosed 35 subjects at the University of Technology, Sydney (UTS), TCM clinic. The practitioners were restricted to a list of the 56 most frequently used TCM diagnoses at the UTS clinic. Up to three diagnostic patterns per subject could be selected, with nominated patterns scored between 1 and 5. Outcome measures: Agreement was determined with two criteria, both expressed as simple percentages: pattern and linearly weighted agreements. Results: The results showed that 23% of practitioners obtained pattern agreement, while 19% demonstrated weighted agreement. Conclusion: There appears to be very low diagnostic agreement between practitioners. This is an important finding. If unchallenged by further investigation, the recognition of such poor diagnostic consensus may lead to rejection of TCM theory before it has been adequately assessed. Diagnostic agreement must be improved so that future investigations into treatment effectiveness or mechanisms of action are made on a valid basis. Additionally, the current TCM diagnostic format must be altered to allow the application of chance-removed statistics or the calculation of a standard error with open populations. This article is the first of a series of three that report problems in TCM diagnostic reliability and proposes solutions to the issues outlined.

Abstract

Background: Bypass surgery (BS) remains the gold standard revascularization strategy in patients with chronic limb-threatening ischemia (CLTI) owing to infrainguinal disease. The Bypass versus Angioplasty for Severe Ischaemia of the Leg (BASIL)-1 trial showed that, in patients with CLTI who survived for 2 years or more, BS resulted in better clinical outcomes. Despite this finding, there has been an increasing trend toward an endovascular-first approach to infrainguinal CLTI. Our aim was to investigate whether changes in practice have impacted the clinical outcomes of BS in our unit 10 years after BASIL-1., Methods: Data for patients who underwent femoropopliteal (FP) BS in BASIL-1 (1999-2004) were retrieved from trial case record forms. The comparator contemporary series (CS) comprised all patients undergoing FP BS for CLTI in our unit between 2009 and 2014. Demographic and clinical outcome data on patients in the CS were collected from the prospectively collected hospital electronic notes. Anatomic patterns of disease in the BASIL-1 and CS cohorts were scored using the Bollinger and GLASS criteria. Statistical analysis was performed in SAS v9.4., Results: There were 128 patients from BASIL-1 and 50 patients in the CS. Baseline age, gender, affected limb, and diabetes prevalence were similar, as were days spent in hospital out to 12 months and length of follow-up. BASIL-1 patients were more likely to be current smokers (P = .000) and had a higher creatinine (P = .04). The 30-day morbidity and mortality were higher in BASIL-1 (45.3% vs 22%; P = .004). There was no significant difference between BASIL-1 and CS with regard to run-off Bollinger (37.7 vs 32.1; P = .167) and IP GLASS (0 vs 0; P = .390) scores, with both groups having a median of two runoff vessels. Amputation-free survival (62% vs 28%; hazard ratio [HR], 1.86; 95% confidence interval [CI], 1.18-2.93; P = .007), limb salvage (85% vs 69%; HR, 2.31; 95% CI, 1.14-4.68; P = .02), overall survival (69% vs 35%; HR, 1.66; 95% CI, 1.00-2.74; P = .05) and major adverse limb events (67% vs 47%; HR, 1.93; 95% CI, 1.15-3.22; P = .01) were all significantly better in BASIL-1., Conclusions: Although 30-day mortality and morbidity were significantly lower, all of the examined longer term clinical outcomes after FP BS were significantly worse in the CS group a decade on from BASIL-1. Further research in the form of prospective cohort studies and randomized controlled trials is urgently required to determine if the CS data reported herein are generalizable to current vascular surgical practice and, if so, to determine the reasons for these unexpected outcomes., (Copyright © 2018 Society for Vascular Surgery.

Abstract

Background: NICE Clinical Guidelines (CG) 168, published in July 2013, recommend specialist vascular referral for all leg ulcers, defined as a break in the skin below the knee that has not healed within two weeks., Aim: To examine the impact of CG168 on the primary care management of leg ulcers using The Health Improvement Network database., Methods: An eligible population of approximately two million adult patients was analysed over two 18-month periods before and after publication of CG168. Those with a new diagnosis of leg ulcers in each time period were analysed in terms of demographics, specialist referral and superficial venous ablation., Results: We identified 7532 and 7462 new diagnoses of leg ulcers in the pre- and post-CG168 cohorts, respectively. Patients with a new diagnosis of leg ulcers were elderly (median age: 77 years both cohorts) and less likely to be male (47% both cohorts). There were 2259 (30.0%) and 2329 (31.2%) vascular service referrals in the pre- and post-CG168 cohorts, respectively (hazard ratio, 1.05, 95% CI: 0.99, 1.11, p = 0.096). The median interval between general practitioner diagnosis and referral was 1.5 days in both cohorts. Patients from both cohorts who were referred for a new diagnosis of leg ulcers were equally likely to receive superficial venous ablation., Conclusions: Disappointingly, we have been unable to demonstrate that publication of NICE CG168 has been associated with a meaningful change in leg ulcer management in primary care in line with guideline recommendations.

Abstract

Objective/background: In July 2013, new UK guidelines recommended that all patients with symptomatic varicose veins (VV) be referred to a specialist vascular service for consideration of superficial venous intervention (SVI). In the UK, general practitioners (GPs) in primary care control access to publicly funded vascular services provided through the National Health Service. GP awareness and concordance with Clinical Guideline (CG)168 recommendations is vital if patients with VV are to receive evidence-based treatment in line with national recommendations. The aim was to assess the UK-wide impact of new guidelines on GP management of VV using a large database of electronic GP records., Methods: An eligible population of patients aged ≥ 18 years was analysed over two 18-month periods, before and after guideline publication. Those with a new diagnosis of VV in each time period were analysed in terms of demographics, specialist referral, compression hosiery prescriptions, and recorded SVI., Results: Analysis included approximately two million patients from 285 GP practices. Before and after CG168 cohorts were well matched. Study populations included 13,014 patients before and 12,466 patients after guideline publication. There was an increase in specialist referrals from 24% (n = 3173) to 28% (n = 3457) (Cox hazard ratio [HR] 1.15, 95% confidence interval [CI] 1.09-1.20; p < .001). Median time to referral was 1.5 days. Prescribed compression hosiery declined from 20% (n = 2558) before the new guidelines to 18% (n = 2292) after the new guidelines (HR 0.93, 95% CI 0.88-0.98; p = .008). There were similar increases in proportions recorded as having SVI, from 3.6% (n = 469) before the new guidelines to 4.2% (n = 526) after the new guidelines (HR 1.16, 95% CI 1.02-1.31; p = .023). There was a statistically significant increase in endothermal ablation after CG168. In Cox models, age, sex, Townsend quintile, and body mass index were significantly related to the chance of referral and SVI., Conclusion: Encouragingly, following publication of National Institute for Health and Care Excellence CG168, there has been a statistically significant improvement in the management of VV in primary care in line with the CG recommendations., (Copyright © 2018 European Society for Vascular Surgery.

Abstract

Background Leg ulcers are a common cause of morbidity and disability and result in significant health and social care expenditure. The UK National Institute for Health and Care Excellence (NICE) Clinical Guideline (CG)168, published in July 2013, sought to improve care of patients with leg ulcers, recommending that patients with a break in the skin below the knee that had not healed within two weeks be referred to a specialist vascular service for diagnosis and management. Aim Determine the impact of CG168 on referrals to a leg ulcer service. Methods Patients referred with leg ulceration during an 18-month period prior to CG168 (January 2012-June 2013) and an 18-month period commencing six months after (January 2014-June 2015) publication of CG168 were compared. Results There was a two-fold increase in referrals (181 patients, 220 legs vs. 385 patients, 453 legs) but no change in mean age, gender or median-duration of ulcer at referral (16.6 vs. 16.2 weeks). Mean-time from referral to specialist appointment increased (4.8 vs. 6 weeks, p = 0.0001), as did legs with superficial venous insufficiency (SVI) (36% vs. 44%, p = 0.05). There was a trend towards more SVI endovenous interventions (32% vs. 39%, p = 0.271) with an increase in endothermal (2 vs. 32 legs, p = 0.001) but no change in sclerotherapy (24 vs. 51 legs) treatments. In both groups, 62% legs had compression. There was a reduction in legs treated conservatively with simple dressings (26% vs. 15%, p = 0.0006). Conclusions Since CG168, there has been a considerable increase in leg ulcer referrals. However, patients are still not referred until ulceration has been present for many months. Although many ulcers are multi-factorial and the mainstay of treatment remains compression, there has been an increase in SVI endovenous intervention. Further efforts are required to persuade community practitioners to refer patients earlier, to educate patients and encourage further investment in chronically underfunded leg ulcer services.

Abstract

Background UK National Institute for Health and Care Excellence (NICE) clinical guidelines (CG) 168, published in July 2013, aimed to improve the management of lower limb venous disease by newly recommending interventional treatment for all people affected by symptomatic varicose veins (VV) and specialist vascular referral for all people suffering from a leg ulcer (LU) that had been present for ≥2 weeks. This study aims to determine if CG168 has increased access to vascular services, particularly for the socially deprived, who might be expected to have greater need for such services. Methods The study was performed in a highly multi-cultural, socio-economically diverse, mixed urban/suburban population of approximately 1.2 million people living in and around East Birmingham, UK. Index of multiple deprivation quintile (IMD-Q) was used as a measure of social deprivation to compare levels of social deprivation of people undergoing interventions for symptomatic VV or referred with an LU during 18-month periods before and after the publication of CG168. The referring general practitioner practices (GPPs) were also recorded. Results There was no change in overall IMD-Q distribution before and after CG168 in terms of VV interventions. However, there was a non-significant increase in proportions of people classified as IMD-Q5 (the most deprived quintile). After CG168, fewer IMD-Q5 people with LU were referred, with a shift in referrals towards those from less socially deprived areas. More GPP referred people with both VV and LU after CG168, and those that referred patients before and after CG168 tended to refer more after CG168. Conclusions CG168 has increased VV interventions as well as the number referred with LU. However, this improvement in access to treatment and referral may have disproportionately favoured the more socio-economic privileged. Professional and public education is required to ensure that the beneficial impact of the CG168 recommendations are maximised and that those with the greatest health needs have equal access to evidence-based management of their venous disease.

Abstract

Objective: The aim was to compare outcomes in a subgroup of patients with infrapopliteal (IP) disease randomised to infrapopliteal vein bypass (VB) or plain balloon angioplasty (PBA) in the original BASIL trial., Methods: A comparison of outcomes from patients randomised to VB or PBA undergoing revascularisation for severe limb ischaemia (SLI) because of IP disease with or without femoropopliteal disease. Data were extracted from case report forms from the BASIL trial. The primary outcome was amputation free survival (AFS); secondary outcomes included overall survival (OS), 30 day mortality and morbidity, freedom from arterial re-intervention, immediate technical success, repeat and crossover interventions, length of hospital stay, and quality of revascularisation., Results: A total of 104 patients were identified in the BASIL study with IP disease, 56 randomised to IP VB, and 48 to IP PBA. Groups were similar at baseline except for more chronic kidney disease and non-steroidal anti-inflammatory drug use in the VB group, and more previous surgical arterial intervention and antihypertensive use in the PBA group. There were no statistically significant differences in AFS or OS; however, clinically important trends were apparent in favour of a VB first strategy. Patients allocated to VB demonstrated significantly quicker relief of rest pain when compared with PBA (p = .005), but no significant differences in improved tissue healing. Median length of index hospital admission was significantly greater in the VB than in the PBA group (18 vs. 10 days, p < .0001) but there was no difference between the two groups in median total hospital stay between randomisation and the primary endpoint (VB 43.5 vs. PBA 42 days)., Conclusions: Further randomised trials, like BASIL-2 and BEST-CLI, are required to determine whether patients with severe limb ischaemia who require IP revascularisation and who are suitable for VB should have bypass or endovascular intervention as their primary revascularisation procedure., (Crown Copyright © 2017.

Abstract

Introduction Lower limb venous disease affects up to one half, and obesity up to one quarter, of the adult population. Many people are therefore affected by, and present to health services for the treatment of both conditions. This article reviews the available evidence of pathophysiological and clinical relationship between obesity and varicose veins, chronic venous insufficiency and ulceration and deep vein thrombosis. Methods A literature search of PubMed and Cochrane libraries was performed in accordance with PRISMA statement from 1946 to 2015, with further article identification from following cited references for articles examining the relationship between obesity and venous disease. Search terms included obesity, overweight, thrombosis, varicose veins, CEAP, chronic venous insufficiency, treatment, endovenous, endothermal, sclerotherapy, bariatric surgery and deep vein thrombosis. Results The proportion of the population suffering from lower limb venous disease and obesity is increasing. Obesity is an important risk factor for all types of lower limb venous disease, and obese patients with lower limb venous disease are more likely to be symptomatic as a result of their lower limb venous disease. The clinical diagnosis, investigation, imaging and treatment of lower limb venous disease in obese people present a number of challenges. The evidence base underpinning medical, surgical and endovenous management of lower limb venous disease in obese people is limited and such treatment may be associated with worse outcomes and increased risks when compared to patients with a normal body mass index. Conclusion Lower limb venous disease and obesity are both increasingly common. As such, phlebologists will be treating ever greater numbers of obese patients with lower limb venous disease, and clinicians in many other specialties are going to be treating a wide range of obesity-related health problems in people with or at risk of lower limb venous disease. Unfortunately, obese people have been specifically excluded from many, if not most, of the pivotal studies. As such, many basic questions remain unanswered and there is an urgent need for research in this challenging and increasingly prevalent patient group.

Abstract

Objective: Although varicose veins are a common cause of morbidity, the UK National Health Service and private medical insurers have previously sought to ration their treatment in a non-evidence based manner in order to limit health-care expenditure and reimbursement. In July 2013, the UK National Institute for Health and Care Excellence published new national Clinical Guidelines (CG168) to promote evidence-based commissioning and management of varicose veins. The aim of this study was to evaluate the impact of CG168 on the referral and management of varicose veins at the Heart of England NHS Foundation Trust, Birmingham, UK., Methods: Interrogation of a prospectively gathered database, provided by the Heart of England NHS Foundation Trust Performance Unit, of patients undergoing interventions for varicose veins since 1 January 2012. Patients treated before (group 1) and after (group 2) publication of CG168 were compared., Results: There were 253 patients, 286 legs (48% male, mean (range) age 54 (20-91) years) treated in group 1, and 417 patients, 452 legs, (46% male, mean (range) age 54 (14-90) years) treated in group 2, an increase of 65%. CG168 was associated with a significant reduction in the use of surgery (131 patients (52%) group 1 vs. 127 patients (30%) group 2, p = 0.0003, χ(2)), no change in endothermal ablation (30 patients (12%) group 1 vs. 45 patients (11%) group 2), a significant increase in ultrasound-guided foam sclerotherapy (92 patients (36%) group 1 and 245 patients (59%) group 2, p = 0.0001, χ(2)) and an increase in treatment for C2/3 disease (53% group 1 and 65.2% group 2, p = 0.0022, χ(2))., Conclusions: Publication of National Institute for Health and Care Excellence CG168 has been associated with a significant increase (65%) in the number of patients treated, referral at an earlier (CEAP C) stage and increased use of endovenous treatment. CG 168 has been highly effective in improving access to, and quality of care, for varicose veins at Heart of England NHS Foundation Trust., (© The Author(s) 2015.)

Abstract

Objective: The last 10 years have seen the introduction into everyday clinical practice of a wide range of novel non-surgical treatments for varicose veins. In July 2013, the UK National Institute for Health and Care Excellence recommended the following treatment hierarchy for varicose veins: endothermal ablation, ultrasound-guided foam sclerotherapy, surgery and compression hosiery. The aim of this paper is to review the randomised controlled trials that have compared endothermal ablation and ultrasound-guided foam sclerotherapy to determine if the level 1 evidence base still supports an "endothermal ablation first" strategy for the treatment of varicose veins., Methods: A PubMed and OVID literature search (until 31 January 2015) was performed and randomised controlled trials comparing endothermal ablation and ultrasound-guided foam sclerotherapy were obtained., Results: Although anatomical success appeared higher with endothermal ablation than ultrasound-guided foam sclerotherapy, clinical success and patient-reported outcomes measures were similar. Morbidity and complication rates were very low and not significantly different between endothermal ablation and ultrasound-guided foam sclerotherapy. Ultrasound-guided foam sclerotherapy was consistently less expensive that endothermal ablation., Conclusions: All endovenous modalities appear to be successful and have a role in modern day practice. Although further work is required to optimise ultrasound-guided foam sclerotherapy technique to maximise anatomical success and minimise retreatment, the present level 1 evidence base shows there is no significant difference in clinical important outcomes between ultrasound-guided foam sclerotherapy and endothermal ablation. As ultrasound-guided foam sclerotherapy is less expensive, it is likely to be a more cost-effective option in most patients in most healthcare settings. Strict adherence to the treatment hierarchy recommended by National Institute for Health and Care Excellence seems unjustified., (© The Author(s) 2015.)

Abstract

Background: Oral antiseptics reduce nosocomial infections and ventilator-associated pneumonia in critically ill medical and surgical patients intubated for prolonged periods. However, the role of oral antiseptics given before and after planned surgery is not clear. The aim of this systematic review and meta-analysis is to determine the effect of oral antiseptics (chlorhexidine or povidone-iodine) when administered before and after major elective surgery., Methods: Searches were conducted of the MEDLINE, EMBASE and Cochrane databases. The analysis was performed using the random-effects method and the risk ratio (RR) with 95 % confidence interval (CI)., Results: Of 1114 unique identified articles, perioperative chlorhexidine was administered to patients undergoing elective surgery in four studies. This identified 2265 patients undergoing elective cardiac surgery, of whom 1093 (48.3 %) received perioperative chlorhexidine. Postoperative pneumonia and nosocomial infections were observed in 5.3 and 20.2 % who received chlorhexidine compared to 10.4 and 31.3 % who received a control preparation, respectively. Oral perioperative chlorhexidine significantly reduced the risk of postoperative pneumonia (RR = 0.52; 95 % CI 0.39-0.71; p < 0.01) and overall nosocomial infections (RR = 0.65; 95 % CI 0.52-0.81; p < 0.01), with no effect on in-hospital mortality (RR = 1.01; 95 % CI 0.49-2.09; p = 0.98)., Conclusions: Perioperative oral chlorhexidine significantly decreases the incidence of nosocomial infection and postoperative pneumonia in patients undergoing elective cardiac surgery. There are no randomised controlled studies of this simple and cheap intervention in patients undergoing elective non-cardiac surgery., Trial Registration: This systematic review was registered with the International prospective register of systematic reviews (PROSPERO). The registration number is CRD42015016063.
