British Society of Gastroenterology guidelines on sedation in gastrointestinal endoscopy.

Over 2.5 million gastrointestinal endoscopic procedures are carried out in the United Kingdom (UK) every year. Procedures are carried out with local anaesthetic r with sedation. Sedation is commonly used for gastrointestinal endoscopy, but the type and amount of sedation administered is influenced by the complexity and nature of the procedure and patient factors. The elective and emergency nature of endoscopy procedures and local resources also have a significant impact on the delivery of sedation. In the UK, the vast majority of sedated procedures are carried out using benzodiazepines, with or without opiates, whereas deeper sedation using propofol or general anaesthetic requires the involvement of an anaesthetic team. Patients undergoing gastrointestinal endoscopy need to have good understanding of the options for sedation, including the option for no sedation and alternatives, balancing the intended aims of the procedure and reducing the risk of complications. These guidelines were commissioned by the British Society of Gastroenterology (BSG) Endoscopy Committee with input from major stakeholders, to provide a detailed update, incorporating recent advances in sedation for gastrointestinal endoscopy.This guideline covers aspects from pre-assessment of the elective 'well' patient to patients with significant comorbidity requiring emergency procedures. Types of sedation are discussed, procedure and room requirements and the recovery period, providing guidance to enhance safety and minimise complications. These guidelines are intended to inform practising clinicians and all staff involved in the delivery of gastrointestinal endoscopy with an expectation that this guideline will be revised in 5-years' time.

Radiofrequency ablation compared with argon plasma coagulation after endoscopic resection of high-grade dysplasia or stage T1 adenocarcinoma in Barrett's esophagus: a randomized pilot study (BRIDE).

BACKGROUND AND AIMS: Endoscopic resection (ER) is safe and effective for Barrett's esophagus (BE) containing high-grade dysplasia (HGD) or mucosal adenocarcinoma (T1A). The risk of metachronous neoplasia is reduced by ablation of residual BE by using radiofrequency ablation (RFA) or argon plasma coagulation (APC). These have not been compared directly. We aimed to recruit up to 100 patients with BE and HGD or T1A confirmed by ER over 1 year in 6 centers in a randomized pilot study. METHODS: Randomization was 1:1 to RFA or APC (4 treatments allowed at 2-month intervals). Recruitment, retention, dysplasia clearance, clearance of benign BE, adverse events, healthcare costs, and quality of life by using EQ-5D, EORTC QLQ-C30, or OES18 were assessed up to the end of the trial at 12 months. RESULTS: Of 171 patients screened, 76 were randomized to RFA (n = 36) or APC (n = 40). The mean age was 69.7 years, and 82% were male. BE was <5 cm (n = 27), 5 to 10 cm (n = 45), and >10 cm (n = 4). Sixty-five patients completed the trial. At 12 months, dysplasia clearance was RFA 79.4% and APC 83.8% (odds ratio [OR] 0.7; 95% confidence interval [CI], 0.2-2.6); BE clearance was RFA 55.8%, and APC 48.3% (OR 1.4; 95% CI, 0.5-3.6). A total of 6.1% (RFA) and 13.3% (APC) had buried BE glands. Adverse events (including stricture rate after starting RFA 3/36 [8.3%] and APC 3/37 [8.1%]) and quality of life scores were similar, but RFA cost $27491 more per case than APC. CONCLUSION: This pilot study suggests similar efficacy and safety but a cost difference favoring APC. A fully powered non-inferiority trial is appropriate to confirm these findings.

Learning from high risk industries may not be straightforward: a qualitative study of the hierarchy of risk controls approach in healthcare.

OBJECTIVE: Though healthcare is often exhorted to learn from 'high-reliability' industries, adopting tools and techniques from those sectors may not be straightforward. We sought to examine the hierarchies of risk controls approach, used in high-risk industries to rank interventions according to supposed effectiveness in reducing risk, and widely advocated as appropriate for healthcare. DESIGN: Classification of risk controls proposed by clinical teams following proactive detection of hazards in their clinical systems. Classification was based on a widely used hierarchy of controls developed by the US National Institute for Occupational Safety and Health (NIOSH). SETTING AND PARTICIPANTS: A range of clinical settings in four English NHS hospitals. RESULTS: The four clinical teams in our study planned a total of 42 risk controls aimed at addressing safety hazards. Most (n = 35) could be classed as administrative controls, thus qualifying among the weakest type of interventions according to the HoC approach. Six risk controls qualified as 'engineering' controls, i.e. the intermediate level of the hierarchy. Only risk control qualified as 'substitution', classified as the strongest type of intervention by the HoC. CONCLUSIONS: Many risk controls introduced by clinical teams may cluster towards the apparently weaker end of an established hierarchy of controls. Less clear is whether the HoC approach as currently formulated is useful for the specifics of healthcare. Valuable opportunities for safety improvement may be lost if inappropriate hierarchical models are used to guide the selection of patient safety improvement interventions. Though learning from other industries may be useful, caution is needed.

Professionalising patient safety? Findings from a mixed-methods formative evaluation of the patient safety specialist role in the English National Health Service.

Objectives: While safety-dedicated professional roles are common in other high-risk industries, in health care they have tended to have a relatively narrow, technical focus. We present initial findings from a mixed-methods evaluation of a novel, senior role with responsibility for leadership of safety in English National Health Service organisations: the patient safety specialist. Methods: We conducted interviews with those responsible for designing, developing and overseeing the introduction of the role. We also carried out a national survey of current patient safety specialists. Data collection and analysis focused on the rationale for the role, its theory of change, and experiences of putting the theory into practice. Results: Interview participants articulated a clear theory of change for the role, highlighting ways in which the focus of the role, the seniority, responsibility and influence of role holders, and the expertise they brought might result in better safety management and speedier implementation of initiatives to manage risk and improve safety. Survey respondents had mixed experiences of the role to date, particularly in terms of material and symbolic support from their organisations. Together, findings from the two datasets indicated the need for a careful balance between strategic and operational activities to secure impact for patient safety specialists while ensuring they were embedded in the realities of clinical work as done-a balance that not all role holders found easy to achieve. Conclusions: The vision for the patient safety specialist role is clear, and supported by a plausible account of how the work of role holders might result in the intended objectives. The degree to which specialists are supported and resourced to deliver on these ambitions, however, varies markedly across organisations.

Risk Controls Identified in Action Plans Following Serious Incident Investigations in Secondary Care: A Qualitative Study.

OBJECTIVES: The impact of incident investigations in improving patient safety may be linked to the quality of risk controls recommended in investigation reports. We aimed to identify the range and apparent strength of risk controls generated from investigations into serious incidents, map them against contributory factors identified in investigation reports, and characterize the nature of the risk controls proposed. METHODS: We undertook a content analysis of 126 action plans of serious incident investigation reports from a multisite and multispeciality UK hospital over a 3-year period to identify the risk controls proposed. We coded each risk control against the contributory factor it aimed to address. Using a hierarchy of risk controls model, we assessed the strength of proposed risk controls. We used thematic analysis to characterize the nature of proposed risk controls. RESULTS: A substantial proportion (15%) of factors identified in investigation reports as contributing to serious incidents were not addressed by identifiable risk controls. Of the 822 proposed risk controls in action plans, most (74%) were assessed as weak, typically focusing on individualized interventions-even when the problems were organizational or systemic in character. The following 6 broad approaches to risk controls could be identified: improving individual or team performance; defining, standardizing, or reinforcing expected practice; improving the working environment; improving communication; process improvements; and disciplinary actions. CONCLUSIONS: The identified shortfalls in the quality of risk controls following serious incident investigations-including a 15% mismatch between contributory factors and aligned risk controls and 74% of proposed risk controls centering on weaker interventions-represent significant gaps in translating incident investigations into meaningful systemic improvements. Advancing the quality of risk controls after serious incident investigations will require involvement of human factors specialists in their design, a theory-of-change approach, evaluation, and curation and sharing of learning, all supported by a common framework.

Factors influencing participation in randomised clinical trials among patients with early Barrett's neoplasia: a multicentre interview study.

OBJECTIVES: Strong recruitment and retention into randomised controlled trials involving invasive therapies is a matter of priority to ensure better achievement of trial aims. The BRIDE (Barrett's Randomised Intervention for Dysplasia by Endoscopy) Study investigated the feasibility of undertaking a multicentre randomised controlled trial comparing argon plasma coagulation and radiofrequency ablation, following endoscopic resection, for the management of early Barrett's neoplasia. This paper aims to identify factors influencing patients' participation in the BRIDE Study and determine their views regarding acceptability of a potential future trial comparing surgery with endotherapy. DESIGN: A semistructured telephone interview study was performed, including both patients who accepted and declined to participate in the BRIDE trial. Interview data were analysed using the constant comparison approach to identify recurring themes. SETTING: Interview participants were recruited from across six UK tertiary centres where the BRIDE trial was conducted. PARTICIPANTS: We interviewed 18 participants, including 11 participants in the BRIDE trial and 7 who declined. RESULTS: Four themes were identified centred around interviewees' decision to accept or decline participation in the BRIDE trial and a potential future trial comparing endotherapy with surgery: (1) influence of the recruitment process and participant-recruiter relationship; (2) participants' views of the design and aim of the study; (3) conditional altruism as a determining factor and (4) participants' perceptions of surgical risks versus less invasive treatments. CONCLUSION: We identified four main influences to optimising recruitment and retention to a randomised controlled trial comparing endotherapies in patients with early Barrett's-related neoplasia. These findings highlight the importance of qualitative research to inform the design of larger randomised controlled trials.

Mindful Application of Aviation Practices in Healthcare.

INTRODUCTION: Evidence supports the efficacy of incorporating select recognized aviation practices and procedures into healthcare. Incident analysis, debrief, safety brief, and crew resource management (CRM) have all been assessed for implementation within the UK healthcare system, a world leader in aviation-based patient safety initiatives. Mindful application, in which aviation practices are specifically tailored to the unique healthcare setting, show promise in terms of acceptance and long-term sustainment. METHODS: In order to establish British healthcare applications of aviation practices, a PubMed search of UK authored manuscripts published between 2005-2016 was undertaken using search terms 'aviation,' 'healthcare,' 'checklist,' and 'CRM.' A convenience sample of UK-authored aviation medical conference presentations and UK-authored patient safety manuscripts were also reviewed. RESULTS: A total of 11 of 94 papers with UK academic affiliations published between 2005-2016 and relevant to aviation modeled healthcare delivery were found. The debrief process, incident analysis, and CRM are the primary practices incorporated into UK healthcare, with success dependent on cultural acceptance and mindful application. CRM training has gained significant acceptance in UK healthcare environments. DISCUSSION: Aviation modeled incident analysis, debrief, safety brief, and CRM training are increasingly undertaken within the UK healthcare system. Nuanced application, in which the unique aspects of the healthcare setting are addressed as part of a comprehensive safety approach, shows promise for long-term success. The patient safety brief and aviation modeled incident analysis are in earlier phases of implementation, and warrant further analysis.Powell-Dunford N, Brennan PA, Peerally MF, Kapur N, Hynes JM, Hodkinson PD.
