Perceptions of online surgical-focused learning amongst surgeons during the COVID pandemic: A scoping review 2020-22.

INTRODUCTION: During the COVID pandemic many centres adopted e-learning as a tool to adhere to social distancing recommendations while continuing to provide ongoing postgraduate medical education. We aimed to complete this scoping review in order to map experience and perceptions amongst surgeons and surgical trainees to remote learning during the COVID pandemic. METHODS: Using Arksey and O'Malley's five step model for conducting a scoping review, a systematic search strategy was undertaken across three online databases SCOPUS, MEDLINE and Web of Science. Only original articles in English in the field of postgraduate education in surgery were included. RESULTS: 44 studies were selected for review. Of these 44, 21 were studies of perception of a newly developed e-learning tool/platform. 17 were surveys of surgeon's attitudes towards e-learning during the COVID pandemic. The remaining 6 studies were studies of knowledge or skills acquired through new e-learning, which included a survey of experience. The United States was the most common country of origin with General Surgery the most represented surgical speciality. Response rates across all three study subgroups were on average >60%. Surgeon's experience of e-learning was reported in only positive terms in 86% (n = 38/44) of studies. CONCLUSIONS: This paper is informative in that it focuses specifically on surgeons' perceptions of a e-learning tools used in addition to skills or knowledge gained. Positive e-learning experience reported in these studies may lead to more blended learning curriculums being developed, deployed and evaluated going forward.

The Role of Physician and Practice Characteristics in the Quality of Diabetes Management in Primary Care: Systematic Review and Meta-analysis.

BACKGROUND: Despite evidence-based guidelines, high-quality diabetes care is not always achieved. Identifying factors associated with the quality of management in primary care may inform service improvements, facilitating the tailoring of quality improvement interventions to practice needs and resources. METHODS: We searched MEDLINE, EMBASE, CINAHL and Web of Science from January 1990 to March 2019. Eligible studies were cohort studies, cross-sectional studies and randomised controlled trials (baseline data) conducted among adults with diabetes, which examined the relationship between any physician and/or practice factors and any objective measure(s) of quality. Studies which examined patient factors only were ineligible. Where possible, data were pooled using random-effects meta-analysis. RESULTS: In total, 82 studies were included. The range of individual quality measures and the construction of composite measures varied considerably. Female physicians compared with males ((odds ratio (OR) = 1.07, 95% CI: 1.04, 1.10), 8 studies), physicians with higher diabetes volume compared with lower volume (OR = 1.24, 95% CI: 1.05-1.47, 4 studies) and practices with Electronic Health Records (EHR) versus practices without (OR = 1.43, 95% CI: 1.11-1.84, 4 studies) were associated with a higher quality of care. There was no association between physician experience, practice location and type of practice and quality. Based on the narrative synthesis, increasing physician age and higher practice socio-economic deprivation may be associated with lower quality of care. DISCUSSION: Identification of physician- and practice-level factors associated with the quality of care (female gender, younger age, physician-level diabetes volume, practice deprivation and EHR use) may explain differences across practices and physicians, provide potential targets for quality improvement interventions and indicate which practices need specific supports to deliver improvements in diabetes care.

Sustaining quality in the community: trends in the performance of a structured diabetes care programme in primary care over 16 years.

AIM: To examine the quality of care delivered by a structured primary care-led programme for people with Type 2 diabetes mellitus in 1999-2016. METHODS: The Midland Diabetes Structured Care Programme provides structured primary care-led management. Trends over time in care processes were examined (using a chi-squared trend test and age- and gender-adjusted logistic regression). Screening and annual review attendance were reviewed. A composite of eight National Institute for Health and Care Excellence-recommended processes was used as a quality indicator. Participants who were referred to diabetes nurse specialists were compared with those not referred (Student's t-test, Pearson's chi-squared test, Wilcoxon-Mann-Whitney test). Proportions achieving outcome targets [HbA1c ≤58 mmol/mol (7.5%), blood pressure ≤140/80 mmHg, cholesterol <5.0 mmol/l] were calculated. RESULTS: Data were available for people with diabetes aged ≥18 years: 1998/1999 (n=336); 2003 (n=843); 2008 (n=988); and 2016 (n=1029). Recording of some processes improved significantly over time (HbA1c , cholesterol, blood pressure, creatinine), and in 2016 exceeded 97%. Foot assessment and annual review attendance declined. In 2016, only 29% of participants had all eight National Institute for Health and Care Excellence processes recorded. A higher proportion of people with diabetes who were referred to a diabetes nurse specialist had poor glycaemic control compared with those not referred. The proportions meeting blood pressure and lipid targets increased over time. CONCLUSIONS: Structured primary care led to improvements in the quality of care over time. Poorer recording of some processes, a decline in annual review attendance, and participants remaining at high risk suggest limits to what structured care alone can achieve. Engagement in continuous quality improvement to target other factors, including attendance and self-management, may deliver further improvements.

Health service utilization and related costs attributable to diabetes.

AIMS: To estimate the health service use and direct healthcare costs attributable to diabetes using best available data and methods. METHODS: A nationally representative sample of adults aged ≥50 years was analysed (n=8107). Health service use in the previous 12 months included the number of general practitioner visits, outpatient department visits, hospital admissions, and accident and emergency department attendances. Multivariable negative binomial regression was used to estimate the associations between diabetes and frequency of visits. Average marginal effects were applied to unit costs for each health service and extrapolated to the total population, calculating the incremental costs associated with diabetes. RESULTS: The prevalence of diabetes was 8.0% (95% CI: 7.4, 8.6). In fully adjusted models, diabetes was associated with additional health service use. Compared to those without diabetes, people with diabetes have, on average, 1.49 (95% CI: 1.10, 1.88) additional general practitioner visits annually. Diabetes was associated with an 87% increase in outpatient visits, a 52% increase in hospital admissions and a 33% increase in accident and emergency department attendances (P<0.001). The incremental cost of this additional service use, nationally, is an estimated €88,894,421 annually, with hospital admissions accounting for 67% of these costs. CONCLUSION: Using robust methods, we identified substantially increased service use attributable to diabetes across the health system. Our findings highlight the urgent need to invest in the prevention and management of diabetes.

Emergency endovascular management of acute thoracic aortic pathology A safe and feasible option.

Endovascular repair has revolutionised the emergency treatment of thoracic aortic disease. We report our 10 year experience using this treatment in emergency cases. A prospectively maintained vascular database was analysed. Patients' medical records and CT images stored on the hospital PACS system were also reviewed. Statistical analysis was done using IBM SPSS V21. There were a total of 59 thoracic aortic stenting procedures of which 33 (60% males with a mean age of 58 yrs) were performed for emergency thoracic pathologies: traumatic transection (n = 10), ruptured aneurysm (n = 6), non-traumatic dissection (n = 8) and penetrating aortic ulcer (n = 9). All patients had self-expanding endografts implanted. Two patients required debranching procedures before the endovascular treatment. Thirty-day mortality was 12.1% (4/33). 70% of patients received a single device. There were 7 procedure related complications, 6 requiring re-intervention: thoracotomy and drainage in 2 patients, proximal graft extension in 2, open drainage of groin haematoma in 1 and open repair of a common femoral artery pseudo-aneurysm in one patient. In total 23 patients were transferred from 11 centres nationwide. There were no mortalities or other complications related to patient transfer from peripheral centres. Although acute thoracic aortic pathology is life threatening, appropriate blood pressure management and treatment of associated injuries can result in favourable outcomes. Endovascular repair is a safe and effective treatment option which enables patients to be treated with reduced morbidity and mortality. Transfer of patients with acute pathology to a tertiary centre can safely be performed.

The prevalence of Type 2 diabetes and related complications in a nationally representative sample of adults aged 50 and over in the Republic of Ireland.

AIM: To investigate the prevalence of diagnosed Type 2 diabetes and its related complications in a nationally representative sample of older adults in the Republic of Ireland. METHODS: Cross-sectional analysis of a population-based sample of adults aged ≥ 50 years from the first wave of The Irish Longitudinal Study on Ageing (TILDA), (2009-2011). Diagnosed Type 2 diabetes prevalence was estimated by self-report or the use of oral hypoglycaemic agents. The prevalence of microvascular and macrovascular complications was determined by self-report. RESULTS: Diagnosed Type 2 diabetes prevalence was 8.4% [95% confidence interval (CI): 7.8-9.0%] and was higher among men [10.3% (95% CI: 9.4-11.2%)] than women [6.6% (95% CI: 5.9-7.5%)]; P ≤ 0.001. Among participants with diagnosed Type 2 diabetes, the overall prevalence of microvascular complications was 26.0% (95% CI: 22.4-30.0%) with no evidence of gender-specific differences (P = 0.7). The overall prevalence of macrovascular complications was 15.1% (95% CI: 12.2-18.4%) and was higher among men [17.8% (95% CI: 14.3-23.1%)] than women [11.4% (95% CI: 7.7-16.4%)]; P ≤ 0.001. CONCLUSIONS: In the absence of a national diabetes register, these findings provide a robust estimate of the national prevalence of diagnosed Type 2 diabetes and level of complications among adults aged 50 years and over in Ireland.

Endovascular versus open repair of ruptured abdominal aortic aneurysm.

INTRODUCTION: Endovascular aneurysm repair (EVAR) is a comparatively less invasive technique than open repair (OR). Debate remains with regard to the benefit of EVAR for patients with ruptured abdominal aortic aneurysm (RAAA). We sought to evaluate and report outcomes of EVAR for RAAA in an Irish tertiary vascular referral centre. METHODS: Patients undergoing emergency surgery for ruptured or symptomatic AAA were identified from theatre logbooks and HIPE database. Retrospective chart review was undertaken. Data were exported to IBM SPSS version 21 for statistical analysis with p < 0.05 considered significant. RESULTS: A total of 41 patients underwent surgery for RAAA. The mean age was 74 years old with a range from 55 to 89 years. The majority (n = 25, 61%) were baseline American Society of Anaesthesiology (ASA) grade 3-4. Of these 56% underwent EVAR with the remaining 44% repaired open. Mortality rate in those undergoing emergency EVAR was 34.8%, compared with 38.9% in those undergoing open surgery. This difference was not statistically significant. The mean overall length of stay was 13 days. With regard to prognostic indicators of patient outcome, increasing patient age was noted to be significantly associated with increased mortality (p = 0.013), as was increased ASA score at time of surgery (p = 0.029). CONCLUSIONS: Mortality rates in those undergoing EVAR for RAAA are comparable with those undergoing open repair. Increasing age and ASA score are significant predictors of mortality in patients with RAAA undergoing intervention.

Laminar airflow and the prevention of surgical site infection. More harm than good?

INTRODUCTION: Laminar airflow (LAF) systems are thought to minimise contamination of the surgical field with airborne microbes and thus to contribute to reducing surgical site infections (SSI). However recent publications have questioned whether LAF ventilation confers any significant benefit and may indeed be harmful. METHODS: A detailed literature review was undertaken through www.Pubmed.com and Google scholar (http://scholar.google.com). Search terms used included "laminar flow". "laminar airflow", "surgical site infection prevention", "theatre ventilation" and "operating room ventilation", "orthopaedic theatre" and "ultra-clean ventilation". Peer-reviewed publications in the English language over the last 50 years were included, up to and including March 2014. RESULTS: Laminar airflow systems are predominantly used in clean prosthetic implant surgery. Several studies have demonstrated decreased air bacterial contamination with LAF using bacterial sedimentation plates placed in key areas of the operating room. However, apart from the initial Medical Research Council study, there are few clinical studies demonstrating a convincing correlation between decreased SSI rates and LAF. Moreover, recent analyses suggest increased post-operative SSI rates. CONCLUSION: It is premature to dispense with LAF as a measure to improve air quality in operating rooms where prosthetic joint surgery is being carried out. However, new multi-centre trials to assess this or the use of national prospective surveillance systems to explore other variables that might explain these findings such as poor operating room discipline are needed, to resolve this important surgical issue.

What next after thermal ablation for varicose veins: non-thermal ablation?

BACKGROUND: Endothermal treatment of the great saphenous vein has become the first line of treatment for superficial venous reflux. Newer treatments, especially non-thermal ablation have potential benefits both for patient acceptability and decreased risk of nerve injury. APPROACH: We describe the current non-thermal options available including advantages and disadvantages. Ultrasound guided foam sclerotherapy avoids the risk of nerve injury, however it is not as effective as endothermal ablation. Mechanochemical endovenous ablation combines mechanical endothelial damage using a rotating wire, with the infusion of a liquid sclerosant (the Clarivein™ system). Reports suggest that this system is safe and effective, eliminating the need for tumescent anaesthesia with no reported case of nerve injury. Finally the VenaSeal™ Sapheon Closure System comprises the endovenous delivery of cyanoacrylate tissue adhesive to the vein causing fibrosis. Peri-operative discomfort seems to be minimal but the complication of thrombophlebitis has been reported in up to 15% of patients. CONCLUSIONS: Non-thermal options promise comparable treatment efficacy without the added morbidity associated with high thermal energies. The potential of treating venous reflux without the risk of nerve damage may change how surgeons approach venous disease.

Surgical attire, practices and their perception in the prevention of surgical site infection.

INTRODUCTION: Clean surgical scrubs, surgical gowns and headgear are worn by operative teams to decrease bacterial contamination and lower surgical site infection (SSI) rates. METHODS: A detailed review was undertaken of peer-reviewed publications and other sources of material in the English language over the last 50 years included. RESULTS: Surgical scrubs should be clean and made of tightly woven material. Studies investigating single-use gowns and drapes versus reusable gowns report conflicting evidence. Double gloving may reduce SSI rates in procedures where no antibiotic prophylaxis was administered. Bacterial contamination of the operative field has been shown to be decreased by the wearing of surgical headgear by the operating team. CONCLUSIONS: Further consideration and better trials are required to determine the impact of different theatre clothing on SSI rates.

The role of topical antibiotics used as prophylaxis in surgical site infection prevention.

Compared with systemic antibiotic therapy, the topical or local delivery of an antibiotic has many potential advantages. However, local antibiotics at the surgical site have received very limited approval in any of the surgical prophylaxis consensus guidelines that we are aware of. A review of the literature was carried out through searches of peer-reviewed publications in PubMed in the English language over a 30 year period between January 1980 and May 2010. Both retrospective and prospective studies were included, as well as meta-analyses. With regard to defining 'topical' or 'local' antibiotic application, the application of an antibiotic solution to the surgical site intraoperatively or immediately post-operatively was included. A number of surgical procedures have been shown to significantly benefit from perioperative topical prophylaxis, e.g. joint arthroplasty, cataract surgery and, possibly, breast augmentation. In obese patients undergoing abdominal surgery, topical surgical prophylaxis is also proven to be beneficial. The selective use of topical antibiotics as surgical prophylaxis is justified for specific procedures, such as joint arthroplasty, cataract surgery and, possibly, breast augmentation. In selective cases, such as obese patients undergoing abdominal surgery, topical surgical prophylaxis is also proven to be beneficial. Apart from these specific indications, the evidence for use of topical antibiotics in surgery is lacking in conclusive randomized controlled trials.

A study of the factors influencing school-going students considering medical careers.

INTRODUCTION: Obtaining a place in an Irish medical school is extremely competitive, a situation mirrored in many other countries. We aimed to determine the factors influencing school students in deciding to study medicine in university. We further determined what level of interest exists in pursuing a surgical career after completion of medical school. METHODS: The Royal College of Surgeons in Ireland hosts an annual "Introduction to Medicine" programme for senior school children. Attendees were surveyed using a Likert scale to examine the factors influencing the group in choosing to study medicine, and pursue surgery as their ultimate career choice. RESULTS: A total of 128 completed the survey, giving a response rate of 100%. The opportunity to help others was most the most influential factors cited by students (97%). Males were significantly more likely to have an interest in a career in surgery rather than medicine (p = 0.003), and ranked "financial reward" (p = 0.036) as a more significant factors in influencing career choice than did females. CONCLUSIONS: A clear understanding of these factors influencing our students in their career choices and a strategy of recruitment based on these is imperative in order to optimize recruitment of students most suited to working as doctors.

Delayed ultraviolet erythema not suppressed by oral prednisolone: a randomized crossover study.

BACKGROUND: The anti-inflammatory potency of topical dermatological corticosteroids in suppressing ultraviolet (UV) erythema is routinely measured. No such model exists to assess the potency of systemically administered steroids. OBJECTIVE: To determine whether or not suppression of delayed UV erythema by a systemic corticosteroid could provide a useful model for assessing the anti-inflammatory potency of systemic corticosteroids. METHODS: We conducted a randomized, placebo-controlled, patient and assessor blinded, crossover study of oral prednisolone effects on the delayed UV-induced erythemal response in normal subjects. Six healthy volunteers were phototested with a xenon arc monochromator and then dosed with 30 mg of oral prednisolone or matching placebo daily for 4 days. Repeat phototesting was performed on the 4th day of dosing. The minimal erythema dose (MED) was assessed immediately after test UV doses were administered and 24 h later. After a 2-week washout period, the dosing and testing were repeated in a crossover fashion. RESULTS: A suppression index (SI) [1/(baseline MED value divided by on prednisolone/placebo value)] allowed comparison of the degree of suppression on and off prednisolone. Oral prednisolone did not significantly suppress the threshold UV erythema response (MED). We may have missed small effects in this study and possibly a larger dose or a longer duration of corticosteroid would have had an effect. Possibly, assessment of corticosteroid potency in suppressing established UV erythema rather than on the development of threshold erythema would have yielded different results. CONCLUSION: The threshold UV erythema suppression model assessed in this study could not distinguish between oral prednisolone and placebo. This UV-erythema suppression test system is not promising as a model to test the anti-inflammatory potency of systemic steroids.

Barriers and facilitators to initial and continued attendance at community-based lifestyle programmes among families of overweight and obese children: a systematic review.

The success of childhood weight management programmes relies on family engagement. While attendance offers many benefits including the support to make positive lifestyle changes, the majority of families referred to treatment decline. Moreover, for those who do attend, benefits are often compromised by high programme attrition. This systematic review investigated factors influencing attendance at community-based lifestyle programmes among families of overweight or obese children. A narrative synthesis approach was used to allow for the inclusion of quantitative, qualitative and mixed-method study designs. Thirteen studies met the inclusion criteria. Results suggest that parents provided the impetus for programme initiation, and this was driven largely by a concern for their child's psychological health and wellbeing. More often than not, children went along without any real reason or interest in attending. Over the course of the programme, however, children's positive social experiences such as having fun and making friends fostered the desire to continue. The stigma surrounding excess weight and the denial of the issue amongst some parents presented barriers to enrolment and warrant further study. This study provides practical recommendations to guide future policy makers, programme delivery teams and researchers in developing strategies to boost recruitment and minimise attrition.

General practitioner views on the determinants of test ordering: a theory-based qualitative approach to the development of an intervention to improve immunoglobulin requests in primary care.

BACKGROUND: Research suggests that variation in laboratory requesting patterns may indicate unnecessary test use. Requesting patterns for serum immunoglobulins vary significantly between general practitioners (GPs). This study aims to explore GP's views on testing to identify the determinants of behaviour and recommend feasible intervention strategies for improving immunoglobulin test use in primary care. METHODS: Qualitative semi-structured interviews were conducted with GPs requesting laboratory tests at Cork University Hospital or University Hospital Kerry in the South of Ireland. GPs were identified using a Health Service Executive laboratory list of GPs in the Cork-Kerry region. A random sample of GPs (stratified by GP requesting patterns) was generated from this list. GPs were purposively sampled based on the criteria of location (urban/rural); length of time qualified; and practice size (single-handed/group). Interviews were carried out between December 2014 and February 2015. Interviews were transcribed verbatim using NVivo 10 software and analysed using the framework analysis method. Emerging themes were mapped to the theoretical domains framework (TDF), which outlines 12 domains that can enable or inhibit behaviour change. The behaviour change wheel and behaviour change technique (BCT) taxonomy were then used to identify potential intervention strategies. RESULTS: Sixteen GPs were interviewed (ten males and six females). Findings suggest that intervention strategies should specifically target the key barriers to effective test ordering, while considering the context of primary care practice. Seven domains from the TDF were perceived to influence immunoglobulin test ordering behaviours and were identified as 'mechanisms for change' (knowledge, environmental context and resources, social/professional role and identity, beliefs about capabilities, beliefs about consequences, memory, attention and decision-making processes and behavioural regulation). Using these TDF domains, seven BCTs emerged as feasible 'intervention content' for targeting GPs' ordering behaviour. These included instructions on how to effectively request the test (how to perform behaviour), information on GPs' use of the test (feedback on behaviour), information about patient consequences resulting from not doing the test (information about health consequences), laboratory/consultant-based advice/education (credible source), altering the test ordering form (restructuring the physical environment), providing guidelines (prompts/cues) and adding interpretive comments to the results (adding objects to the environment). These BCTs aligned to four intervention functions: education, persuasion, environmental restructuring and enablement. CONCLUSIONS: This study has effectively applied behaviour change theory to identify feasible strategies for improving immunoglobulin test use in primary care using the TDF, 'behaviour change wheel' and BCT taxonomy. The identified BCTs will form the basis of a theory-based intervention to improve the use of immunoglobulin tests among GPs. Future research will involve the development and evaluation of this intervention.

Radiofrequency ablation: an assessment of clinical and cost efficacy.

BACKGROUND: Varicose veins are common and frequently cause patient distress. In recent years, Radiofrequency ablation (RFA) has emerged as a minimally invasive alternative to traditional open venous ligation surgery. AIMS: The aim of this study was to directly compare RFA and open saphenofemoral ligation. METHODS: This was a single-centre retrospective cohort study. Consecutive patients undergoing surgical management over a 2-year period commencing from January 2011 were studied. Radiological success, peri-operative serological testing and hospital length of stay were documented. Procedural cost was calculated. A focused cohort analysis was undertaken to compare the initial 50 RFA procedures performed with the last 50. RESULTS: During the study period, 296 patients underwent surgical intervention. A total of 204 patients underwent RFA. Sixty-six percent of all patients were female. RFA was associated with a reduction in overnight hospital stay (18 vs. 78 %, P = <0.001) when compared with open ligation with a success rate of 98 %. No significant inter-group difference was noted for 30-day readmission (p = 0.203). Focused cohort analysis identified an increase in hospital day case activity (74 vs. 90 %, p = 0.002), which contributed to a reduction in procedural cost (€1,024 vs. €971, p = 0.003) over the study period. CONCLUSIONS: Radiofrequency ablation is a viable alternative to open repair offering excellent efficacy. It is however associated with a higher procedural cost than the open surgical option.

Trends in blindness due to diabetic retinopathy among adults aged 18-69years over a decade in Ireland.

AIMS: To describe trends in the incidence of visual impairment and blindness due to diabetic retinopathy among adults aged 18-69years in Ireland between 2004 and 2013. METHODS: Data on visual impairment due to diabetic retinopathy in adults aged 18-69years or over who are registered with the National Council for the Blind of Ireland, (2004-2013) were analysed. Annual incidence rates were calculated for the adult population and the population with diagnosed diabetes. Poisson regression was used to test for changes in rates over time. The relative, attributable and population risk of blindness and visual impairment due to diabetic retinopathy were calculated for 2013. RESULTS: Over the decade, the prevalence of diagnosed diabetes increased from 2.1% to 3.6%. Among people with diagnosed diabetes, the incidence of visual impairment due to diabetic retinopathy increased from 6.4 (95% CI 2.4-13.9) per 100,000 in 2004 to 11.7 (95% CI 5.9-21.0) per 100,000 in 2013. The incidence of blindness due to diabetic retinopathy varied from 31.9 per 100,000 (95% CI 21.6-45.7) in 2004 to 14.9 per 100,000 (95% CI 8.2-25.1) in 2013. CONCLUSIONS: Our findings indicate the need for increased attention to preventive measures for microvascular complications among adults with diabetes in Ireland. Retinopathy screening has been standardised in Ireland, these findings provide useful baseline statistics to monitor the impact of this population-based screening programme.
