Disseminating technology in global surgery.

BACKGROUND: Effective dissemination of technology in global surgery is vital to realize universal health coverage by 2030. Challenges include a lack of human resource, infrastructure and finance. Understanding these challenges, and exploring opportunities and solutions to overcome them, are essential to improve global surgical care. METHODS: This review focuses on technologies and medical devices aimed at improving surgical care and training in low- and middle-income countries. The key considerations in the development of new technologies are described, along with strategies for evaluation and wider dissemination. Notable examples of where the dissemination of a new surgical technology has achieved impact are included. RESULTS: Employing the principles of frugal and responsible innovation, and aligning evaluation and development to high scientific standards help overcome some of the challenges in disseminating technology in global surgery. Exemplars of effective dissemination include low-cost laparoscopes, gasless laparoscopic techniques and innovative training programmes for laparoscopic surgery; low-cost and versatile external fixation devices for fractures; the LifeBox pulse oximeter project; and the use of immersive technologies in simulation, training and surgical care delivery. CONCLUSION: Core strategies to facilitate technology dissemination in global surgery include leveraging international funding, interdisciplinary collaboration involving all key stakeholders, and frugal scientific design, development and evaluation.

Do ultrasound guided trochanteric bursa injections of corticosteroid for greater trochanteric pain syndrome provide sustained benefit and are imaging features associated with treatment response?

AIM: To assess intra-bursal corticosteroid injections (ICSI) efficacy and duration of action in the management of greater trochanteric pain syndrome (GTPS). The secondary aim was to identify patient and ultrasound (US) features predictive of treatment response. MATERIALS AND METHODS: Consecutive prospectively recruited patients undergoing US-guided ICSI therapy for GTPS received baseline pre-injection questionnaires assessing pain at rest and activity, demographics and comorbidities. Baseline US and radiography findings were reported prospectively. Follow-up was performed at 6 weeks and 6 and 12 months, and change in pain scores assessed using the Wilcoxon signed rank test. Logistic regression examined associations between demographics, US findings, and a clinically significant reduction in pain score (≥50%). RESULTS: Over 6 months, 127 patients were recruited with a median age of 63.5 years and 90% were female. The greatest pain reduction was between baseline and 6 weeks at activity (median 8 versus 5, p<0.001). The majority of patients noted a reduction in pain score, but the percentage of patients receiving a ≥50% reduction at 6 weeks, 6 months, and 12 months for pain at rest was 41%, 37%, and 36%, respectively. Regression models suggested only gluteus medius bursitis was weakly associated with pain reduction. CONCLUSION: ICSIs confer a benefit in pain reduction to a large proportion of patients in the short term, but this may not be reduced by a clinically significant amount. This small effect size and lack of predictive imaging features suggests initial management including subsequent steroid injection could be provided without imaging guidance in the majority of cases.

Longitudinal analysis of reporting and quality of systematic reviews in high-impact surgical journals.

BACKGROUND: The PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) Statement aims to optimize the reporting of systematic reviews. The performance of the PRISMA Statement in improving the reporting and quality of surgical systematic reviews remains unclear. METHODS: Systematic reviews published in five high-impact surgical journals between 2007 and 2015 were identified from online archives. Manuscripts blinded to journal, publication year and authorship were assessed according to 27 reporting criteria described by the PRISMA Statement and scored using a validated quality appraisal tool (AMSTAR, Assessing the Methodological Quality of Systematic Reviews). Comparisons were made between studies published before (2007-2009) and after (2011-2015) its introduction. The relationship between reporting and study quality was measured using Spearman's rank test. RESULTS: Of 281 eligible manuscripts, 80 were published before the PRISMA Statement and 201 afterwards. Most manuscripts (208) included a meta-analysis, with the remainder comprising a systematic review only. There was no meaningful change in median compliance with the PRISMA Statement (19 (i.q.r. 16-21) of 27 items before versus 19 (17-22) of 27 after introduction of PRISMA) despite achieving statistical significance (P = 0·042). Better reporting compliance was associated with higher methodological quality (rs = 0·70, P < 0·001). CONCLUSION: The PRISMA Statement has had minimal impact on the reporting of surgical systematic reviews. Better compliance was associated with higher-quality methodology.

Challenges and opportunities in academic neurosurgery.

Clinical academia aims to bridge the gap between clinicians and scientists, by combining academic activity with clinical practice. The term 'clinical academics' generally refers to clinicians who have protected time within their job plans for undertaking academic activities. Engagement with academic activity by trainees is not only essential to fulfil necessary curriculum competencies, but also allows them to explore areas of interest outside of clinical practice and develop advanced academic skills. This article provides an overview of different routes into academic neurosurgery, and discusses the advantages and difficulties in pursuing this career path. It also covers the differences between postgraduate research degrees and explores the different job plan models available at consultant level. Academic neurosurgery is a rewarding career and opportunities should be made available to those who wish to explore it further. Developing academic careers may have a positive impact on wider workforce planning strategies and improve the delivery of high-quality evidence-based neurosurgical care.
