Assessing the attitude of surgical trainees towards virtual reality simulation: A national cross-sectional questionnaire study.

BACKGROUND: We performed a cross sectional study to determine the attitudes of surgical trainees and medical students towards virtual reality (VR) simulation in surgical training. A survey was devised through an iterative process before distribution to surgical trainees, foundation year doctors and medical students through online platforms. METHODS: The survey was disseminated within the United Kingdom through social media and email correspondence, in co-operation with national surgical organisations. 91 trainees responded from a variety of clinical specialities. RESULTS: VR technology in surgical training was viewed positively, with 91.3% of trainees agreeing that VR should be both an adjunct in surgical training as well as a competency-based assessment tool. Barriers to access were present, with access notably more challenging for senior surgeons. CONCLUSION: Virtual reality surgical simulation in surgical training is beginning to emerge as a genuine high-fidelity, low-risk solution to the lack of surgical case volume trainees are currently experiencing.

A District General Hospital Trauma Service Response to COVID-19: Lessons Learnt.

OBJECTIVE: This article seeks to evaluate and outline the changes made to the trauma and orthopaedic department in a district general hospital in the United Kingdom during the COVID-19 pandemic. We detail the approach in relation to surgical management, workforce optimisation and our general reflections as a department. METHODS: We interviewed, collated and have subsequently described the adaptations implemented by our department. We have collected their shared strategy and reflections on how the COVID-19 pandemic affected our department. RESULTS: Alterations were implemented to mitigate the effects of the COVID-19 pandemic. A strategy focused on ensuring the workforce remained healthy, and patient care pathways were altered as minimally as possible. CONCLUSIONS:  As a unit, a sense of heightened vigilance needs to remain for the foreseeable future. Decisive action by departmental leadership, alongside a cohesive and open, has allowed for our trauma service to continue largely unchanged. This analysis serves as an important aide-memoire for future periods of extreme uncertainty.

Evaluating Healthcare Worker Competence in the Correct Use of Personal Protective Equipment in the COVID Era: A Quality Improvement Project.

INTRODUCTION: Throughout the coronavirus disease 2019 pandemic, personal protective equipment (PPE) guidance has rapidly evolved. Healthcare workers (HCWs) should use PPE correctly to reduce the risk of nosocomial transmission of the coronavirus. We predict a lack of training regarding correct PPE usage amongst HCWs and introduce a low-resource method of training. METHODS: HCWs from various disciplines at a District General Hospital self-rated their ability in utilising PPE using uncontrolled pre- and post-session 16-item questionnaires following a single PPE training session. Participant responses were analysed using Student's t-test for independent (unpaired) samples. RESULTS: Of 64 participants, 37 participants (59%) received any prior PPE training. Six participants (9%) previously received specific severe acute respiratory syndrome coronavirus 2 PPE training. Survey scores were higher in the post-test than the pre-test group. CONCLUSION: This study highlights the lack of formal PPE training amongst HCWs and the need for establishing PPE training as part of the mandatory training of HCWs.

A Meta-analysis of Clinical, Patient-Reported Outcomes and Cost of DIEP versus Implant-based Breast Reconstruction.

INTRODUCTION: Comparative data on clinical outcomes and cost of deep inferior epigastric perforator (DIEP) and implant-based reconstruction (IBR) are limited. We conducted a Preferred Reporting Items for Systematic Review and Meta-analysis-compliant systematic review and meta-analysis to compare clinical, patient-reported outcomes (PROs) and cost. METHODS: The protocol was published a priori on PROSPERO (CRD42017072557). EMBASE, MEDLINE, Google Scholar, Cochrane Controlled Register of Trials, Science Citation Index, and ClinicalTrials.gov were searched from January 1994 to August 2018. Two independent reviewers evaluated the articles for inclusion. Study quality was assessed using Grading of Recommendations Assessment, Development, and Evaluation, and risk of bias (RoB) was assessed using Cochrane's RoB in Nonrandomized Studies of Interventions tool. RESULTS: Out of 6,381 articles screened, 16 were included [unilateral 782 DIEPs, 376 implants; mean age 49 years, follow-up (months): DIEP 29.9; IBR 35.5]. Mean flap loss and fat necrosis rates were 3.97% (SD 4.90) and 9.67% (SD 17.0), respectively. There was no difference in mean length of stay {standard mean difference 0.63 [confidence interval (CI) -9.17 to 10.43]; P =0.90}. The number of reoperations for complications was significantly lower in DIEP versus IBR [SMD -0.29 (CI -0.48 to -0.09); P < 0.01]. There were no randomized controlled trials. Study quality was low with high RoB. One study reported $11,941/Quality-adjusted Life Year incremental cost-effectiveness ratio for DIEP, with higher breast Quality-adjusted Life Year (DIEP 19.5; IBR 17.7) using Breast Questionnaire; 3 studies evaluated cost, favoring DIEP. Two comparative studies evaluating PROs favored DIEP. CONCLUSIONS: DIEP reconstruction maybe more cost-effective and yield superior PROs. However, poor-quality, bias-ridden studies limit the findings. Adequate reporting of core outcome measures is required to minimize reporting bias and facilitate evidence synthesis. Prospective, multicenter, cohort studies using robust patient-reported outcome measures (PROMs) tools, evaluating cost-effectiveness and contributing to national/international registries, will facilitate national-level policy and shared decision-making.

Systematic review of the efficacy of fat grafting and platelet-rich plasma for wound healing.

Adipose-derived stem cells found in fat grafts may have significant healing properties. When fat is combined with autologous platelet-rich plasma (PRP), there may be enhanced healing effects due to the pro-angiogenic and anti-inflammatory effects of PRP. This study aimed to evaluate the current evidence on fat grafting in combination with PRP for wound healing to establish the efficacy of this technique. A comprehensive search in the MEDLINE, EMBASE, CENTRAL, Science Citation Index, and Google Scholar databases (to March 2017) was conducted to identify studies on fat grafting and PRP for wound healing. Case series of less than 3 cases and studies only describing harvest technique were excluded. The database identified 571 articles, of which 3 articles that used a combination of fat and PRP for wound healing (1 RCT and 2 case series) were included in this review. A total of 69 wounds in 64 patients were treated with an average wound size of 36.32cm2 . Of these, 67% of wounds achieved complete healing. When reported, the mean time to healing was 7.5 weeks for those who underwent a single treatment. There were no significant complications in any patients. The combination of fat grafting and PRP may achieve adequate wound healing with relatively quick wound healing time compared with standard wound management options. However, evidence is extremely limited, and further studies are required to evaluate its efficacy for wound healing.

Protocol for a systematic review of the efficacy of fat grafting and platelet-rich plasma for wound healing.

BACKGROUND: The use of fat grafting as a reconstructive surgical option is becoming much more common. Adipose-derived stem cells found in fat grafts are believed to facilitate wound healing via differentiation into fibroblasts and keratinocytes and the release of pro-healing growth factors. Several small studies have shown a positive effect of fat grafting in healing of wounds of a variety of aetiologies. When fat is combined with autologous platelet-rich plasma (PRP), there may be enhanced healing effects. This may be due to the pro-angiogenic and anti-inflammatory effects of PRP. We aim to synthesise the current evidence on combination fat grafting and PRP for wound healing to establish the efficacy of this technique. METHODS/DESIGN: We will conduct a comprehensive literature search in the MEDLINE, EMBASE, CENTRAL, Science Citation Index, and Google Scholar databases (up to July 2017) to identify studies on fat grafting and PRP for wound healing. All primary studies and systematic reviews of these studies will be included, except case reports and case series with fewer than three patients, to evaluate the outcome of fat grafting and PRP on wound healing either on its own or when compared to other studies. Primary outcome measures are expected to be the proportion of total wounds healed at 12 weeks and the average wound healing time (time for 100% re-epithelialisation). Expected secondary outcome measures are the proportion of wounds achieving 50% wound healing, the type of wound benefitting most from fat grafting, economic evaluation, health-related quality of life, and adverse events. Subgroup analysis will be performed for the proportions of wounds healed based on wound aetiology. DISCUSSION: This review will provide robust evidence of the efficacy of fat grafting and PRP for wound healing. This is an emerging technique, and this review is expected to guide clinical practice and ongoing research aimed at improving wound care. SYSTEMATIC REVIEW REGISTRATION: PROSPERO CRD42016049881.
