John IJ, Choo H, Pettengell CJ, et al., 2021, Patient views on surgeon-specific outcome reporting in vascular surgery: novel validated patient questionnaire study, Annals of Surgery, Vol: 274, Pages: e1030-e1037, ISSN: 0003-4932
BACKGROUND: SSMD are used to enhance transparency, improve quality and facilitate patient choice. The use of SSMD is controversial, but patients' views on such data are largely unknown. OBJECTIVES: The aim of this study was therefore to explore the views of patients and to identify their priorities for outcome reporting in vascular surgery. METHODS: A prospective questionnaire study of 165 patients receiving care in a single academic vascular unit was performed. Data on patients' current understanding and use of SSMD, together with future priorities were collected. RESULTS: Of the 165 patients 80% were unaware of SSMD. 72% thought they should be made aware of the data, although 63% thought they were likely to misinterpret the results. The majority recognized the utility of SSMD to inform treatment (60%) and surgeon (53%) choice. The majority prioritize the patient-surgeon relationship (90%) and past experiences of care (71%) when making treatment decisions. A significant majority (66% vs 49%; P < 0.005) would favour hospital-level to surgeon-level data. The main patient priorities for future outcome reporting were waiting list length (56%), the quality of hospital facilities (55%), and patient satisfaction (54%). CONCLUSIONS: The aims of SSMD reporting are not currently being met, and both patients and healthcare professionals have shared concerns over the nature and usefulness of the data. Patients express a preference for hospital-level outcomes and prioritize the experience of receiving care over outcomes when making treatment decisions. Future outcome reporting should include patient-directed hospital-level metrics that are readily accessible and understood by all.

Aufegger L, Soane E, Darzi A, et al., 2021, Shared leadership in tertiary care: design of a simulation for patient safety decision-making in healthcare management teams, BMJ Simulation & Technology Enhanced Learning, Vol: 7, Pages: 216-222, ISSN: 2056-6697
Introduction Simulation-based training (SBT) on shared leadership (SL) and group decision-making (GDM) can contribute to the safe and efficient functioning of a healthcare system, yet it is rarely incorporated into healthcare management training. The aim of this study was design, develop and validate a robust and evidence-based SBT to explore and train SL and GDM.Method Using a two-stage iterative simulation design approach, 103 clinical and non-clinical managerial students and healthcare professionals took part in an SBT that contained real-world problems and opportunities to improve patient safety set within a fictional context. Self-report data were gathered, and a focus group was conducted to address the simulation’s degree of realism, content, relevance, as well as areas for improvement.Results Participants experienced the simulation scenario, the material and the role assignment as realistic and representative of real-world tasks and decision contexts, and as a good opportunity to identify and enact relevant tasks, behaviours and knowledge related to SL and GDM. Areas for improvement were highlighted with regard to involving an actor who challenges SL and GDM; more preparatory time to allow for an enhanced familiarisation of the content; and, video debriefs to reflect on relevant behaviours and team processes.Conclusions Our simulation was perceived as an effective method to develop SL and GDM within the context of patient safety and healthcare management. Future studies could extend this scenario method to other areas of healthcare service and delivery, and to different sectors that require diverse groups to make complex decisions.
Chan C, Sounderajah V, Normahani P, et al., 2021, Wearable activity monitors in home based exercise therapy for patients with intermittent claudication: a systematic review, European Journal of Vascular and Endovascular Surgery, Vol: 61, Pages: 676-687, ISSN: 1078-5884
OBJECTIVE: Intermittent claudication (IC) can severely limit functional capacity and quality of life. Supervised exercise therapy is the recommended first line management; however, this is often limited by accessibility, compliance and cost. As such, there has been an increased interest in the use of wearable activity monitors (WAMs) in home based telemonitoring exercise programmes for claudicants. This review aims to evaluate the efficacy of WAM as a feedback and monitoring tool in home based exercise programmes for patients with IC. DATA SOURCES: A search strategy was devised. The databases MEDLINE, EMBASE, and Web of Science were searched through to April 2020. REVIEW METHODS: Randomised trials and prospective trials were included. Eligible trials had to incorporate WAMs as a feedback tool to target walking/exercise behaviour. The primary outcome was the change in walking ability. Study quality was assessed with risk of bias tool. RESULTS: A total of 1148 records were retrieved. Of these, eight randomised controlled trials and one prospective cohort study, all of which compared a WAM intervention against standard care and/or supervised exercise, met the inclusion criteria. Owing to heterogeneity between studies, no meta-analysis was conducted. WAM interventions improved measures of walking ability (heterogeneous outcomes such as maximum walking distance, claudication distance and six minute walk distance), increased daily walking activity (steps/day), cardiovascular metrics (maximum oxygen consumption), and quality of life. CONCLUSION: There is some evidence that home based WAM interventions are beneficial for improving walking ability and quality of life in patients with IC. However, existing studies are limited by inadequate sample size, duration, and appropriate power. Achieving consensus on outcome reporting and study methods, as well as maximising device adherence, is needed.

BackgroundEuropean countries face fiscal pressure regarding the long-term sustainability of their healthcare system due to increasing levels of public health expenditures and mounting demographic pressures. The promotion of generic drugs is considered to be an efficient means to tackle these challenges; however, market diffusion remains slow. The aim of this study was to investigate the impact of price and brand cues on purchase intentions by means of Direct-to-Consumer (DTC) advertising, and to build on the market cue evaluation model by Dodd et al.MethodsParticipants rated purchase intentions on six DTC adverts varying in price and brand information, followed by self-reports on purchase intentions, attitudes towards generics, brand loyalty, price consciousness, as well as perceptions of quality, risk and value. Open-ended questions explored attitudes toward generic drugs.ResultsBrand information and purchase intentions were mediated by perceived risk and perceived quality, while price information influenced purchase intention through perceptions of quality, risk and value. Consumers’ purchase behaviour was furthermore influenced by unawareness and misconceptions, past experiences, and advertising as a decision-making tool.ConclusionsAdvertisements, including price and brand information, are an important tool to improve consumers’ awareness of the availability of different OTC drugs. Practical and theoretical implications are discussed.

Aufegger L, Bùi KH, Bicknell C, et al., 2020, Designing a paediatric hospital information tool with children, parents, and healthcare staff: a UX study, BMC Pediatrics, Vol: 20, ISSN: 1471-2431
BACKGROUND: The hospital patient pathway for having treatment procedures can be daunting for younger patients and their family members, especially when they are about to undergo a complex intervention. Opportunities to mentally prepare young patients for their hospital treatments, e.g. for surgical procedures, include tools such as therapeutic clowns, medical dolls, or books and board games. However, while promising in reducing pre-operative anxiety and negative behaviours, they may be resource intensive, costly, and not always readily available. In this study, we co-designed a digital hospital information system with children, parents and clinicians, in order to prepare children undergoing medical treatment. METHOD: The study took place in the UK and consisted of two parts: In part 1, we purposively sampled 37 participants (n=22 parents, and n=15 clinicians) to understand perceptions and concerns of an hospital information platform specifically design for and addressed to children. In part 2, 14 children and 11 parents attended an audio and video recorded co-design workshop alongside a graphic designer and the research team to have their ideas explored and reflected on for the design of such information technology. Consequently, we used collected data to conduct thematic analysis and narrative synthesis. RESULTS: Findings from the survey were categorised into four themes: (1) the prospect of a hospital information system (parents' inputs); (2) content-specific information needed for the information system (parents' and clinicians' inputs); (3) using the virtual information system to connect young patients and parents (parents' inputs); and (4) how to use the virtual hospital information system from a clinician's perspective (clinicians' inputs). In contrast, the workshop highlighted points in times children were most distressed/relaxed, and derived the ideal hospital visit in both their and their parents' perspectives. CONCLUSIONS: The findings support the use of v

Background As systems become more complex, shared leadership (SL) has been suggested to have a dominant role in improving cross-functional working tailored to organisational needs. Little, however, is known about the benefits of SL in healthcare management, especially for UK’s recently formed integrated care system (ICS). The aim of this study was to understand current attitudes, barriers and needs of clinical and non-clinical managers sharing leadership responsibilities in the ICS.Method Twenty clinical and non-clinical leaders in 15 organisations were interviewed to understand current cross-functional leadership collaborations, and the potential SL may have on the recently established ICS in the National Health Service (NHS). The data were transcribed and analysed thematically.Results Findings showed perceptions and experiences of clinical and non-clinical healthcare management in relation to: (1) motivation to execute a leadership position, including the need to step up and a sense of duty; (2) attitudes towards interdisciplinary working, which is reflected in conflicts due to different values and expertise; (3) SL skills and behaviours, including the need for mutual understanding and cooperative attitudes by means of effective communication and collaboration; and (4) barriers to achieve SL in the ICS, such as bureaucracy, and a lack of time and support.Conclusions SL may help improve current leadership cultures within the NHS; however, for SL to have a tangible impact, it needs to be delivered as part of leadership development for doctors in postgraduate training, and development programmes for aspiring, emerging and established leaders, with clear lines of communication.

Ramjeeawon A, Sharrock AE, Morbi A, et al., 2020, Using Fully-Immersive Simulation Training with Structured Debrief to Improve Nontechnical Skills in Emergency Endovascular Surgery., J Surg Educ, Vol: 77, Pages: 1300-1311
OBJECTIVE: Assess whether fully-immersive simulation training with structured debriefing of a standardized emergency thoracic endovascular aortic repair (TEVAR) scenario improves team-work performance of the lead surgeon. Secondary aims: assess whether technical skills (TS) and radiation safety behaviors (RSB) improved concurrently. DESIGN: Pre-post study. SETTING: UK-based training days. PARTICIPANTS: General and vascular surgical trainees (n = 16). INTERVENTION(S): Fully-immersive simulation training with structured debriefing of a standardized emergency TEVAR scenario. Following standardized emergency TEVAR technical training, trainees led 2 standardized fully-immersive endovascular surgery simulations, with scripted support from a passive surgical team. A non-TS (NTS) structured debrief was delivered following simulations. NTS were assessed using the validated observational teamwork assessment for surgery tool post hoc using video recordings of simulations. TS were assessed through time taken to complete each step of the procedure, as defined during technical training. RSB were assessed through checking for presence of pre-defined actions and the length of time fluoroscopy was used during each simulation. RESULTS: Total observational teamwork assessment for surgery scores improved following structured debrief (p = 0.005, median 52.55/90 vs 73.0/90), alongside all constituent domains - communication (p < 0.001, median 11.7/20 vs 16.6/20), coordination (p < 0.001, median 8.6/15 vs 13.4/15), cooperation (p < 0.001, median 13.15/20 vs 16.35/20), leadership (p < 0.001, median 8.70/15 vs 11.30/15) and monitoring (p < 0.001, median 9.85/20 vs 14.85/20). TS improved; time to complete 12 of 13 procedural steps improved (p < 0.027). Fluoroscopy time (seconds) decreased (p = 0.339, 543.6 vs 495.5), frequency lead surgeons checked the team were wearing leads increased (p = 0.125, 3 vs 7) and asked the team to step back before screening increased (p = 0.003

BACKGROUND: The treatment of distal (below the knee) deep vein thrombosis (DVT) is not clearly established. Distal DVT can either be treated with anticoagulation, or monitored with close follow-up to detect progression to the proximal veins (above the knee), which requires anticoagulation. Proponents of this monitoring strategy base their decision to withhold anticoagulation on the fact that progression is rare and most people can be spared from potential bleeding and other adverse effects of anticoagulation. OBJECTIVES: To assess the effects of different treatment interventions for people with distal (below the knee) deep vein thrombosis (DVT). SEARCH METHODS: The Cochrane Vascular Information Specialist searched the Cochrane Vascular Specialised Register, CENTRAL, MEDLINE, Embase and CINAHL databases and World Health Organization International Clinical Trials Registry Platform and ClinicalTrials.gov trials registers to 12 February 2019. We also undertook reference checking to identify additional studies. SELECTION CRITERIA: Randomised controlled trials (RCTs) for the treatment of distal DVT. DATA COLLECTION AND ANALYSIS: Two review authors independently selected trials and extracted data. We resolved disagreements by discussion. Primary outcomes of interest were recurrence of venous thromboembolism (VTE), DVT and major bleeding and follow up ranged from three months to two years. We performed fixed-effect model meta-analyses with risk ratio (RRs) and 95% confidence intervals (CIs). We assessed the certainty of the evidence using GRADE. MAIN RESULTS: We identified eight RCTs reporting on 1239 participants. Five trials randomised participants to anticoagulation for up to three months versus no anticoagulation. Three trials compared anticoagulation treatment for different time periods. Anticoagulant compared to no intervention or placebo for distal DVT treatment Anticoagulation with a vitamin K antagonist (VKA) reduced the risk of recurrent VTE during follow-up compa

BACKGROUND: The optimum management of isolated penetrating aortic ulceration (PAU), with no associated intramural hematoma or aortic dissection is not clear. We evaluate the short- and long-term outcomes in isolated PAU to better inform management strategies. METHODS: We conducted a retrospective review of 43 consecutive patients (mean age, 72.2 years; 26 men) with isolated PAU (excluding intramural hematoma/aortic dissection) managed at a single tertiary vascular unit between November 2007 and April 2019. Twenty-one percent had PAU of the arch, 62% of the thoracic aorta, and 17% of the abdominal aorta. Conservative and surgical groups were analyzed separately. Primary outcomes included mortality, PAU progression, and interventional complications. RESULTS: Initially, 67% of patients (29/43) were managed conservatively; they had significantly smaller PAU neck widths (P = .04), PAU depths (P = .004), and lower rates of associated aneurysmal change (P = .004) compared with those initially requiring surgery. Four patients (4/29) initially managed conservatively eventually required surgical management at a mean time interval of 49.75 months (range, 9.03-104.33 months) primarily owing to aneurysmal degeneration. Initially, 33% of patients (14/43) underwent surgical management; 7 of the 14 procedures were urgent. Of the 18 patients, 17 eventually managed with surgical intervention had an endovascular repair; 2 of the 17 endovascular cases involved supra-aortic debranching, six used scalloped, fenestrated, or chimney stents. The overall long-term mortality was 30% (mean follow-up, 48 months; range, 0-136 months) with no significant difference between the conservatively and surgically managed groups (P = .98). No aortic-related deaths were documented during follow-up in those managed conservatively. There was no in-hospital mortality after surgical repair. Of these 18 patients, two required reintervention within 30 days for t

Background: Vascular surgery has one of the highest unplanned 30-day readmission rates of all surgical specialities. The degree to which these may be avoidable and the optimal strategies to reduce their occurrence is unknown. The aim of this study was to identify and classify avoidable 30-day readmissions in patients undergoing vascular surgery in order to plan targeted interventions to reduce their occurrence, improve outcomes and reduce cost.Methods: A retrospective analysis of discharges over a 12-month period from a single tertiary vascular unit was performed. A multidisciplinary panel conducted a manual case note review to identify and classify those 30-day unplanned emergency readmissions deemed avoidable.Results: An unplanned 30-day readmission occurred in 72/885 (8.1%) admissions. These unplanned readmissions were deemed avoidable in 50.0% (36/72) and were most frequently due to unresolved medical issues (19/36, 52.8%) and inappropriate admission with the potential for outpatient management (7/36, 19.4%). A smaller number were due to inadequate social care provision (4/36, 11.1%) and the occurrence of other avoidable adverse events (4/36, 11.1%). Conclusion: Half of all 30-day readmissions in vascular patients are potentially avoidable. Multidisciplinary coordination of inpatient care and the transition from hospital to community care following discharge need to be improved.

Objective:To determine if psychosocial factors moderate the relationship between surgical complications and quality of life (QoL).Summary Background:Patients who experience surgical complications have significantly worse post-operative QoL than patients with an uncomplicated recovery. Psychosocial factors, such as coping style and level of social support influence how people deal with stressful events, but it is unclear if they impact on QoL following a surgical complication. These findings can inform the development of appropriate interventions that support patients post-operatively. Methods:This is a longitudinal cohort study; data were collected at pre-op, 1 month post-op, 4 months post-op and 12 months post-op. A total of 785 patients undergoing major elective gastro-intestinal, vascular or cardio-thoracic surgery were recruited from 28 National Health Service (NHS) sites in England and Scotland took part in the study.Results:Patients who experience major surgical complications report significantly reduced levels of physical and mental QoL (p<0.05) but they make a full recovery over time. Findings indicate that a range of psychosocial factors such as the use of humor as a coping style and the level of health care professional support may moderate the impact of surgical complications on QoL.Conclusion:Surgical complications alongside other socio-demographic and psychosocial factors contribute to changes in QoL; the results from this exploratory study suggest that interventions that increase the availability of healthcare professional support and promote more effective coping strategies prior to surgery may be useful, particularly in the earlier stages of recovery where QoL is most severely compromised. However, these relationships should be further explored in longitudinal studies that include other types of surgery and employ rigorous recruitment and follow up procedures.
Aufegger L, Bicknell C, Soane E, et al., 2019, Understanding health management and safety decisions using signal processing and machine learning, BMC Medical Research Methodology, Vol: 19, ISSN: 1471-2288
BackgroundSmall group research in healthcare is important because it deals with interaction and decision-making processes that can help to identify and improve safer patient treatment and care. However, the number of studies is limited due to time- and resource-intensive data processing. The aim of this study was to examine the feasibility of using signal processing and machine learning techniques to understand teamwork and behaviour related to healthcare management and patient safety, and to contribute to literature and research of teamwork in healthcare.MethodsClinical and non-clinical healthcare professionals organised into 28 teams took part in a video- and audio-recorded role-play exercise that represented a fictional healthcare system, and included the opportunity to discuss and improve healthcare management and patient safety. Group interactions were analysed using the recurrence quantification analysis (RQA; Knight et al., 2016), a signal processing method that examines stability, determinism, and complexity of group interactions. Data were benchmarked against self-reported quality of team participation and social support. Transcripts of group conversations were explored using the topic modelling approach (Blei et al., 2003), a machine learning method that helps to identify emerging themes within large corpora of qualitative data.ResultsGroups exhibited stable group interactions that were positively correlated with perceived social support, and negatively correlated with predictive behaviour. Data processing of the qualitative data revealed conversations focused on: (1) the management of patient incidents; (2) the responsibilities among team members; (3) the importance of a good internal team environment; and (4) the hospital culture.ConclusionsThis study has shed new light on small group research using signal processing and machine learning methods. Future studies are encouraged to use these methods in the healthcare context, and to conduct further research
