Integrating simulation into surgical training: a qualitative case study of a national programme.

BACKGROUND: Applying simulation-based education (SBE) into surgical curricula is challenging and exacerbated by the absence of guidance on implementation processes. Empirical studies evaluating implementation of SBE interventions focus primarily on outcomes. However, understanding the processes involved in organising, planning, and delivering SBE adds knowledge on how best to develop, implement, and sustain surgical SBE. This study used a reform of early years surgical training to explore the implementation of a new SBE programme in Scotland. It aimed to understand the processes that are involved in the relative success (or failure) when implementing surgical SBE interventions. METHODS: This qualitative case study, underpinned by social constructionism, used publicly available documents and the relevant surgical SBE literature to inform the research focus and contextualise data obtained from semi-structured interviews with core surgical trainees (n = 46), consultant surgeons (n = 25), and key leaders with roles in surgical training governance in Scotland (n = 7). Initial data coding and analysis were inductive. Secondary data analysis was then undertaken using Normalisation Process Theory (NPT). NPTs' four constructs (coherence, cognitive participation, collective action, reflexive monitoring) provided an explanatory framework for scrutinising how interventions are implemented, embedded, and integrated into practice, i.e. the "normalisation" process. RESULTS: Distributed leadership (individual SBE initiatives assigned to faculty but overall programme overseen by a single leader) and the quality improvement practise of iterative refinement were identified as key novel processes promoting successful normalisation of the new SBE programme. Other processes widely described in the literature were also identified: stakeholder collaboration, personal contacts/relational processes, effective communication, faculty development, effective leadership, and tight programme management. The study also identified that learners valued SBE activities in group- or team-based social environments over isolated deliberate practice. CONCLUSIONS: SBE is most effective when designed as a comprehensive programme aligned to the curriculum. Programmes incorporating both group-based and isolated SBE activities promote deliberate practice. Distributed leadership amongst faculty attracts wide engagement integral to SBE programme implementation, while iterative programme refinement through regular evaluation and action on feedback encourages integration into practice. The knowledge contributed by critically analysing SBE programme implementation processes can support development of much needed guidance in this area.

Context matters in curriculum reform: An analysis of change in surgical training.

INTRODUCTION: Education and training reforms are typically devised by accreditation bodies and rolled out nationally. This top-down approach is positioned as contextually independent, yet context is highly influential in shaping the impact of change. Given this, it is critical to consider how curriculum reform plays out as it meets local settings. We have therefore used a national-level curriculum reform process of surgical training, Improving Surgical Training (IST), to examine the influence of context in IST implementation across two UK countries. METHODS: Adopting a case study approach, we used document data for contextualisation purposes and semi-structured interviews with key stakeholders across multiple organisations (n = 17, plus four follow-up interviews) as our main source of data. Initial data coding and analysis were inductive. We followed this with a secondary analysis using Engeström's second-generation activity theory nested within an overarching framework of complexity theory to help tease out some key elements of IST development and implementation. RESULTS: The introduction of IST into the surgical training system was historically situated within a landscape of previous reforms. IST's aims collided with existing practices and rules, thus creating tensions. In one country, the systems of IST and surgical training came together to some extent, mostly due to processes of social networks, negotiation and leverage nested in a relatively cohesive setting. These processes were not apparent in the other country, and instead of transformative change, the system contracted. Change was not integrated, and the reform was halted. CONCLUSIONS: Our use of a case study approach and complexity theory deepens understanding of how history, systems and contexts interact to facilitate or inhibit change within one area of medical education. Our study paves the way for further empirical work examining the influence of context in curriculum reform, and thus determining how best to bring about change in practice.

Scotland's "Incentivised Laparoscopy Practice" programme: Engaging trainees with take-home laparoscopy simulation.

BACKGROUND: The transfer validity of portable laparoscopy simulation is well established. However, attempts to integrate take-home simulation into surgical training have met with inconsistent engagement worldwide, as for example in our 2014-15 study of an Incentivised Laparoscopy Practice programme (ILPv1). Drawing on learning from our subsequent multi-centre study examining barriers and facilitators, we revised the programme for 2018 onwards. We now report on engagement with the 2018-2022 versions of this home-based simulation programme (ILP v2.1-2.3). METHODS: In ILP v2.1-2.3, three consecutive year-groups of new-start Core Surgical Trainees (n = 48, 46 and 53) were loaned portable simulators. The 6-month education programme included induction, technical support, and intermittent feedback. Six tasks were prescribed, with video instruction and charting of metric scores. Video uploads were required and scored by faculty. A pass resulted in an eCertificate, expected at Annual Review (but not mandatory for progression). ILP was set within a wider reform, "Improving Surgical Training". RESULTS: ILP v2.1-2.3 saw pass rates of 94%, 76% and 70% respectively (45/48, 35/46 and 37/53 trainees), compared with only 26% (7/27) in ILP v1, despite now including some trainees not intending careers in laparoscopic specialties. The ILP v2.2 group all reported their engagement with the whole simulation strategy was hampered by the COVID19 pandemic. CONCLUSIONS: Simply providing take-home simulators, no matter how good, is not enough. To achieve trainee engagement, a whole programme is required, with motivated learners, individual and group practice, intermittent feedback, and clear goals and assessments. ILP is a complex intervention, best understood as a "reform within a reform, within a context."

Scratching beneath the surface: How organisational culture influences curricular reform.

INTRODUCTION: Curricular reform is often proposed as the means to improve medical education and training. However, reform itself may not lead to noticeable change, possibly because the influence of organisational culture on change is given insufficient attention. We used a national reform of early-years surgical training as a natural opportunity to examine the interplay between organisational culture and change in surgical education. Our specific research question was: in what ways did organisational culture influence the implementation of Improving Surgical Training (IST)? METHODS: This is a qualitative study underpinned by social constructivism. Interviews were conducted with core surgical trainees (n = 46) and their supervising consultants (n = 25) across Scotland in 2020-2021. Data coding and analysis were initially inductive. The themes indicated the importance of many cultural factors as barriers or enablers to IST implementation. We therefore carried out a deductive, secondary data analysis using Johnson's (1988) cultural web model to identify and examine the different elements of organisational culture and their impact on IST. RESULTS: The cultural web enabled a detailed understanding of how organisational culture influenced IST implementation as per Johnson's six elements-Rituals and Routines (e.g. departmental rotas), Stories (e.g. historical training norms and culture), Symbols (e.g. feedback mechanisms, visibility and value placed on education), Power Structures (e.g. who has the power in local contexts), Organisational Structures (e.g. relationships and accountability) and the Control System (e.g. consultant job plans and service targets)-and how these interact. However, it did not shed light on the influence of exogenous events on change. CONCLUSION: Our data reveal cultural reasons why this curricular reform met with varying degrees of success across different hospital sites, reinforcing that curricular reform is not simply about putting recommendations into practice. Many different aspects of context must be considered when planning and evaluating change in medical education and training.

"It's making me think outside the box at times": a qualitative study of dynamic capabilities in surgical training.

Craft specialties such as surgery endured widespread disruption to postgraduate education and training during the pandemic. Despite the expansive literature on rapid adaptations and innovations, generalisability of these descriptions is limited by scarce use of theory-driven methods. In this research, we explored UK surgical trainees' (n = 46) and consultant surgeons' (trainers, n = 25) perceptions of how learning in clinical environments changed during a time of extreme uncertainty (2020/2021). Our ultimate goal was to identify new ideas that could shape post-pandemic surgical training. We conducted semi-structured virtual interviews with participants from a range of working/training environments across thirteen Health Boards in Scotland. Initial analysis of interview transcripts was inductive. Dynamic capabilities theory (how effectively an organisation uses its resources to respond to environmental changes) and its micro-foundations (sensing, seizing, reconfiguring) were used for subsequent theory-driven analysis. Findings demonstrate that surgical training responded dynamically and adapted to external and internal environmental uncertainty. Sensing threats and opportunities in the clinical environment prompted trainers' institutions to seize new ways of working. Learners gained from reconfigured training opportunities (e.g., splitting operative cases between trainees), pan-surgical working (e.g., broader surgical exposure), redeployment (e.g., to medical specialties), collaborative working (working with new colleagues and in new ways) and supervision (shifting to online supervision). Our data foreground the human resource and structural reconfigurations, and technological innovations that effectively maintained surgical training during the pandemic, albeit in different ways. These adaptations and innovations could provide the foundations for enhancing surgical education and training in the post-pandemic era.

Improving prescribing of extended prophylaxis for venous thromboembolism at discharge in patients who underwent surgery for colorectal cancer.

AIMS/BACKGROUND: Prophylaxis at discharge is important in mitigating venous thromboembolism events from colorectal cancer and major abdominopelvic surgery, both of which are risk factors for venous thromboembolism. Foundation doctors frequently rotate between departments, and so rely on departmental induction and/or handing down of knowledge to prescribe extended venous thromboembolism prophylaxis upon discharge. METHODS: A retrospective audit of all patients who underwent surgery for colorectal cancer at The County Hospital, Hereford, between 1 August 2018 and 31 August 2019, was undertaken to assess departmental compliance with guidance from the National Institute for Health and Care Excellence. RESULTS: A total of 181 patients underwent elective surgery and 29 patients had emergency surgery. The initial audit revealed a cyclical 4-monthly decline that coincided with foundation doctors' rotations. Six multidisciplinary interventions were implemented. Reaudit demonstrated 100% compliance with prescribing of extended venous thromboembolism prophylaxis at discharge. No venous thromboembolism events 30 days post operation were noted. CONCLUSIONS: A multidisciplinary approach involving educating health professionals about the importance of extended venous thromboembolis prophylaxis in patients who have undergone surgery for colorectal cancer can be effective in improving compliance with prescribing practices at discharge.

Acute pancreatitis: current perspectives on diagnosis and management.

The last two decades have seen the emergence of significant evidence that has altered certain aspects of the management of acute pancreatitis. While most cases of acute pancreatitis are mild, the challenge remains in managing the severe cases and the complications associated with acute pancreatitis. Gallstones are still the most common cause with epidemiological trends indicating a rising incidence. The surgical management of acute gallstone pancreatitis has evolved. In this article, we revisit and review the methods in diagnosing acute pancreatitis. We present the evidence for the supportive management of the condition, and then discuss the management of acute gallstone pancreatitis. Based on the evidence, our local institutional pathways, and clinical experience, we have produced an outline to guide clinicians in the management of acute gallstone pancreatitis.

Continence and micturition: an anatomical basis.

Urinary incontinence remains an important clinical problem worldwide, having a significant socio-economic, psychological, and medical burden. Maintaining urinary continence and coordinating micturition are complex processes relying on interaction between somatic and visceral elements, moderated by learned behavior. Urinary viscera and pelvic floor must interact with higher centers to ensure a functionally competent system. This article aims to describe the relevant anatomy and neuronal pathways involved in the maintenance of urinary continence and micturition. Review of relevant literature focusing on pelvic floor and urinary sphincters anatomy, and neuroanatomy of urinary continence and micturition. Data obtained from both live and cadaveric human studies are included. The stretch during bladder filling is believed to cause release of urothelial chemical mediators, which in turn activates afferent nerves and myofibroblasts in the muscosal and submucosal layers respectively, thereby relaying sensation of bladder fullness. The internal urethral sphincter is continuous with detrusor muscle, but its arrangement is variable. The external urethral sphincter blends with fibers of levator ani muscle. Executive decisions about micturition in humans rely on a complex mechanism involving communication between several cerebral centers and primitive sacral spinal reflexes. The pudendal nerve is most commonly damaged in females at the level of sacrospinous ligament. We describe the pelvic anatomy and relevant neuroanatomy involved in maintaining urinary continence and during micturition, subsequently highlighting the anatomical basis of urinary incontinence. Comprehensive anatomical understanding is vital for appropriate medical and surgical management of affected patients, and helps guide development of future therapies.

The effect of SN-6, a novel sodium-calcium exchange inhibitor, on contractility and calcium handling in isolated failing rat ventricular myocytes.

BACKGROUND AND PURPOSE: Specific Na(+) /Ca(2+) exchanger (NCX) inhibition is a potential strategy to correct reduced contractility and depleted sarcoplasmic reticulum (SR) Ca(2+) content in heart failure (HF). SN-6, a benzyloxyphenyl derivative and proposed selective NCX inhibitor, could be used for this purpose. This study aimed to evaluate the effects of SN-6 on contractility and Ca(2+) handling in normal and failing rat cardiomyocytes. EXPERIMENTAL APPROACH: HF was induced in rats by coronary artery ligation. Left ventricular myocytes were isolated and superfused with increasing concentrations of SN-6. KEY RESULTS: Sarcomere shortening, induced by field-stimulation, was reduced in amplitude with increasing concentrations of SN-6 compared with control solution. This effect was greater in failing cells. Kinetics of contractility (time to 90% peak and time to 50% relaxation) were significantly faster. Despite this, intracellular Ca(2+) transients demonstrated no change in the peak amplitude at low concentrations of SN-6, suggesting that SN-6 may affect myofilament sensitivity to Ca(2+) . Ten micro molar SN-6 significantly reduced peak Ca(2+) amplitude by 61.57% and 64.73% in normal and failing cells, respectively. Diastolic Ca(2+) was significantly increased at 1 µM SN-6. SR Ca(2+) content, assessed by rapid application of caffeine, was reduced in failing cells with 1 µM SN-6. Peak ICa , measured by whole-cell patch clamping, was significantly reduced in normal and failing myocytes at 1 µM SN-6. CONCLUSIONS AND IMPLICATIONS: Our data suggest that SN-6 is not a selective inhibitor of NCX and impairs contractility and Ca(2+) handling. Its use, together with similar putative NCX blockers, in correcting the contractile abnormalities of heart failure requires further studies.

Genetic background affects function and intracellular calcium regulation of mouse hearts.

AIMS: The genetic background is currently under close scrutiny when determining cardiovascular disease progression and response to therapy. However, this factor is rarely considered in physiological studies, where it could influence the normal behaviour and adaptive responses of the heart. We aim to test the hypothesis that genetic strain variability is associated with differences in excitation-contraction coupling mechanisms, in particular those involved in cytoplasmic Ca(2+) regulation, and that they are concomitant to differences in whole-heart function and cell morphology. METHODS AND RESULTS: We studied 8- to 10-week-old male C57BL/6, BALB/C, FVB, and SV129 mice. Echocardiography and radiotelemetry were used to assess cardiac function in vivo. FVB mice had increased left ventricular ejection fraction and fractional shortening with significantly faster heart rate (HR) and lack of diurnal variation of HR. Confocal microscopy, sarcomere length tracking, and epifluorescence were used to investigate cell volume, t-tubule density, contractility, and Ca(2+) handling in isolated ventricular myocytes. Sarcomere relaxation and time-to-peak of the Ca(2+) transient were prolonged in BALB/C myocytes, with more frequent Ca(2+) sparks and significantly higher sarcoplasmic reticulum (SR) Ca(2+) leak. There were no strain differences in the contribution of different Ca(2+) extrusion mechanisms. SV129 had reduced SR Ca(2+) leak with elevated SR Ca(2+) content and smaller cell volume and t-tubule density compared with myocytes from other strains. CONCLUSION: These results demonstrate that a different genetic background is associated with physiological differences in cardiac function in vivo and differences in morphology, contractility, and Ca(2+) handling at the cellular level.
