RESUMEN
Background: Surgical site infections (SSI) complicate up to 40% of surgical procedures, leading to increased patient morbidity and mortality. Previous research identified disparities in SSI prevention guidelines and clinical practices across different institutions. The study aims to identify variations in SSI prevention practices within and between specialties and financial systems and provide a representation of existing SSI preventative measures to help improve the standardization of SSI prevention practices. Methods: This collaborative cross-sectional survey will be aimed at pan-surgical specialties internationally. The study has been designed and will be reported in line with the CROSS and CHERRIES standards. An international study steering committee will design and internally validate the survey in multiple consensus-based rounds. This will be based on SSI prevention measures outlined in the CDC (2017), WHO (2018), NICE (2019), Wounds UK (2020) and the International Surgical Wound Complications Advisory Panel (ISWCAP) guidelines. The questionnaire will include demographics, SSI surveillance, preoperative, peri-operative and postoperative SSI prevention. Data will be collected on participants' surgical specialty, operative grade, of practice and financial healthcare system of practice. The online survey will be designed and disseminated using QualtricsXM Platform™ through national and international surgical colleges and societies, in addition to social media and snowballing. Data collection will be open for 3 months with reminders, and raking will be used to ascertain the sample. Responses will be analyzed, and the chi-square test used to evaluate the impact of SSI prevention variables on responses. Discussion: Current SSI prevention practice in UK Vascular surgery varies considerably, with little consensus on many measures. Given the inconsistency in guidelines on how to prevent SSIs, there is a need for standardization. This survey will investigate the disparity in SSI preventative measures between different surgical fields and countries.
RESUMEN
BACKGROUND: Keratinocyte or nonmelanoma skin cancer (NMSC) is the commonest malignancy worldwide. The usual treatment is surgical excision. Current guidelines underestimate incomplete excision rates. OBJECTIVES: We aimed to determine the risk of incomplete excision of NMSCs through a systematic review and meta-analysis of primary clinical studies. METHODS: A PRISMA-compliant systematic review and meta-analysis was performed using methodology proposed by Cochrane (PROSPERO CRD42019157936). A comprehensive search strategy was applied to MEDLINE, Embase, Scopus, CINAHL, EMCare, Cochrane Library and the grey literature (January 2000-27 November 2019). All studies were included except those on Mohs micrographic surgery, frozen section or biopsies. Abstract screening and data extraction were performed in duplicate. Risk of bias was assessed using a tool for prevalence/incidence studies. The primary outcome was the proportion of incomplete surgical excisions. A random-effects model for pooling of binomial data was used. Differences between proportions were assessed by subgroup meta-analysis and meta-regression, which were presented as risk ratios (RRs). RESULTS: Searching identified 3477 records, with 110 studies included, comprising 53 796 patients with 106 832 basal cell carcinomas (BCCs) and 21 569 squamous cell carcinomas (SCCs). The proportion of incomplete excisions for BCC was 11·0% [95% confidence interval (CI) 9·7-12·4] and for SCC 9·4% (95% CI 7·6-11·4). Proportions of incomplete excisions by specialty were: dermatology, BCCs 6·2% and SCCs 4·7%; plastic surgery, BCCs 9·4% and SCCs 8·2%; general practitioners, BCCs 20·4% and SCCs 18·9%. The risk of incomplete excision for general practitioners was four times that of dermatologists for both BCCs (RR 3·9, 95% CI 2·0-7·3) and SCCs (RR 4·8, 95% CI 1·0-22·8). Studies were heterogeneous (I2 = 98%) and at high risk of bias. CONCLUSIONS: The proportion of incomplete excisions is higher than previously reported. Excisions performed by specialists may lower the risk of incomplete excision.

BACKGROUND: Intermittent claudication (IC) is a common condition that causes pain in the lower limbs when walking and has been shown to severely impact the quality of life (QoL) of patients. The QoL is therefore often regarded as an important measure in clinical trials investigating intermittent claudication. To date, no consensus exits on the type of life questionnaire to be used. This review aims to examine the QoL questionnaires used in trials investigating peripheral arterial disease (PAD). MATERIAL AND METHODS: A systematic review of randomised clinical trials including a primary analysis of QoL via questionnaire was performed. Trials involving patients with diagnosed PAD were included (either clinically or by questionnaire). Any trial which had QoL as the primary outcome data was included with no limit being placed on the type of questionnaire used. RESULTS: The search yielded a total of 1845 articles of which 31 were deemed appropriate for inclusion in the review. In total, 14 different QoL questionnaires were used across 31 studies. Of the questionnaires 24.06% were missing at least one domain when reported in the results of the study. Mean standard deviation varied widely based on the domain reported, particularly within the SF36. DISCUSSION: Despite previous recommendations for Europewide standardisation of quality of life assessment, to date no such tool exists. This review demonstrated that a number of different questionnaires remain in use, that their completion is often inadequate and that further evidence-based guidelines on QoL assessment are required to guide future research.
RESUMEN
OBJECTIVE: Dialkylcarbomoyl chloride (DACC)-coated dressings (Leukomed Sorbact and Cutimed Sorbact) irreversibly bind bacteria at the wound surface that are then removed when the dressing is changed. They are a recent addition to the wound care professional's armamentarium and have been used in a variety of acute and chronic wounds. This systematic review aims to assess the evidence supporting the use of DACC-coated dressings in the clinical environment. METHOD: We included all reports of the clinical use of DACC-coated dressings in relation to wound infection. Medline, Embase, CENTRAL and CINAHL databases were searched to September 2016 for studies evaluating the role of DACC-coated dressings in preventing or managing wound infections. RESULTS: We identified 17 studies with a total of 3408 patients which were included in this review. The DACC-coating was suggested to reduce postoperative surgical site infection rates and result in chronic wounds that subjectively looked cleaner and had less bacterial load on microbiological assessments. CONCLUSION: Existing evidence for DACC-coated dressings in managing chronic wounds or as a surgical site infection (SSI) prophylaxis is limited but encouraging with evidence in support of DACC-coated dressings preventing and treating infection without adverse effects.

BACKGROUND: Alcohol-related presentations to hospital have been increasing in the UK in recent years, including the occurrence of acute withdrawal. This study sought to better characterize the clinical features, patterns of treatment and outcomes in this patient group. METHODS: Patients admitted to the Acute Medical Unit of York Hospital due to acute alcohol withdrawal are normally treated according to a protocol that involves both fixed-dose and symptom-triggered drug administration. Admissions between 2010 and 2011 inclusive were studied. RESULTS: There were 211 admission episodes solely due to acute alcohol withdrawal, involving 127 patients (97 men, 76.4%) with median age of 45 years (interquartile range: 39-52 years). There was a high prevalence of depression (34%), alcoholic liver disease (22%) and drug misuse (12%). Total dose of chlordiazepoxide varied between 0 and 610 mg and tapered rapidly after the first day of admission. Vitamin supplements were administered to >90% of patients, including parenteral and oral in 74%, parenteral alone in 9% and oral alone in 9%. A specialist alcohol nurse reviewed patients while in hospital in 40% of cases. Approximately one-third of patients had multiple admissions for alcohol withdrawal during the study period. CONCLUSION: A high prevalence of physical and mental health disorders was observed. The local policy permitted high initial chlordiazepoxide doses and prompt downward titration, with a broad range of doses between individuals. Approximately 10% required no specific therapy, and there may be opportunities for developing alternative pathways for delivery of care in an ambulatory setting for these patients.
