RESUMO
OBJECTIVES: To investigate how information about innovative surgical procedures is communicated to patients. BACKGROUND: Despite the national and international guidance that patients should be informed whether a procedure is innovative and has uncertain outcomes, little is known about current practice. METHODS: This qualitative study followed 7 "case studies" of surgical innovation in hospitals across the United Kingdom. Preoperative interviews were conducted with clinician innovators (n=9), preoperative real-time consultations between clinicians and patients were audio-recorded (n=37). Patients were interviewed postoperatively (n=30). Data were synthesized using thematic analytical methods. RESULTS: Interviews with clinicians demonstrated strong intentions to inform patients about the innovative nature of the procedure in a neutral manner, although tensions between fully informing patients and not distressing them were raised. In the consultations, only a minority of clinicians actually made explicit statements about, (1) the procedure being innovative, (2) their limited clinical experience with it, (3) the paucity of evidence, and (4) uncertainty/unknown outcomes. Discussions about risks were generalized and often did not relate to the innovative component. Instead, all clinicians optimistically presented potential benefits and many disclosed their own positive beliefs. Postoperative patient interviews revealed that many believed that the procedure was more established than it was and were unaware of the unknown risks. CONCLUSIONS: There were contradictions between clinicians' intentions to inform patients about the uncertain outcomes of innovative and their actual discussions with patients. There is a need for communication interventions and training to support clinicians to provide transparent data and shared decision-making for innovative procedures.

INTRODUCTION: The number of laparoscopic liver resections undertaken has increased. However, lesions located postero-superiorly are difficult to access. This may be overcome by the novel use of trans-thoracic port(s). Methods for the safe and transparent introduction of new and modified surgical procedures are limited and a summary of these issues, for minimally invasive trans-thoracic liver resections (MITTLR), is lacking. This study aims to understand and summarize technique description, governance procedures, and reporting of outcomes for MITTLR. METHODS: A systematic literature search to identify primary studies of all designs describing MITTLR was undertaken. How patients were selected for the new technique was examined. The technical components of MITTLR were identified and summarized to understand technique development over time. Governance arrangements (eg, Institutional Review Board approval) and steps taken to mitigate harm were recorded. Finally, specific outcomes reported across studies were documented. RESULTS: Of 2067 screened articles, 16 were included reporting data from 145 patients and 6 countries. Selection criteria for patients was explicitly stated in 2 papers. No studies fully described the technique. Five papers reported ethical approval and 3 gave details of patient consent. No study reported on steps taken to mitigate harm.Technical outcomes were commonly reported, for example, blood loss (15/16 studies), operative time (15/16), and margin status (11/16). Information on patient-reported outcomes and costs were lacking. CONCLUSIONS: Technical details and governance procedures were poorly described. Outcomes focussed on short term details alone. Transparency is needed for reporting the introduction of new surgical techniques to allow their safe dissemination.

BACKGROUND: Consent remains a crucial, yet challenging, cornerstone of clinical practice. The ethical, legal and professional understandings of this construct have evolved away from a doctor-centred act to a patient-centred process that encompasses the patient's values, beliefs and goals. This alignment of consent with the philosophy of shared decision-making was affirmed in a recent high-profile Supreme Court ruling in England. The communication of information is central to this model of health care delivery but it can be difficult for doctors to gauge the information needs of the individual patient. The aim of this paper is to describe 'core information sets' which are defined as a minimum set of consensus-derived information about a given procedure to be discussed with all patients. Importantly, they are intended to catalyse discussion of subjective importance to individuals. MAIN BODY: The model described in this paper applies health services research and Delphi consensus-building methods to an idea orginally proposed 30 years ago. The hypothesis is that, first, large amounts of potentially-important information are distilled down to discrete information domains. These are then, secondly, rated by key stakeholders in multiple iterations, so that core information of agreed importance can be defined. We argue that this scientific approach is key to identifying information important to all stakeholders, which may otherwise be communicated poorly or omitted from discussions entirely. Our methods apply systematic review, qualitative, survey and consensus-building techniques to define this 'core information'. We propose that such information addresses the 'reasonable patient' standard for information disclosure but, more importantly, can serve as a spring board for high-value discussion of importance to the individual patient. CONCLUSION: The application of established research methods can define information of core importance to informed consent. Further work will establish how best to incorporate this model in routine practice.

A patient presented with impending airway obstruction due to a dislodged interim maxillary obturator. The removal was complicated by the presence of severe trismus due to previous maxillectomy and recent radiotherapy. An emergency tracheotomy with the patient under local anesthetic was required to provide a definitive airway and to permit subsequent removal of the obturator with the patient under general anesthesia. The situation highlights the risks associated with interim obturators while awaiting the provision of an ideally fitted, well-retained, definitive obturator. Displaced obturators are potentially life threatening and difficult to remove in emergency situations.

Surgery remains an important, often primary, treatment modality in the management of head and neck cancers (HNCs). Malignant disease of the oral cavity, oropharynx and larynx may all be treated by surgery alone, or in combination with chemotherapy and/or radiotherapy.Recent decades have seen significant advances in the surgical management of HNC. Refinement of surgical technique (particularly in microvascular surgery), improved training standards, advances in peri-operative care and more recent innovations, including transoral robotic surgery, have resulted in better survival and quality of life outcomes.This paper provides the dental practitioner with an overview of common surgical procedures used in the management of HNC, with an emphasis on the management of squamous cell cancers affecting the oral cavity, oropharynx and larynx. Throughout, there is an emphasis on the implications for the dental team of cancer and its surgical management, at each of these anatomical sites.

Aerosol generating procedures (AGPs) are defined as any procedure releasing airborne particles <5 µm in size from the respiratory tract. There remains uncertainty about which dental procedures constitute AGPs. We quantified the aerosol number concentration generated during a range of periodontal, oral surgery and orthodontic procedures using an aerodynamic particle sizer, which measures aerosol number concentrations and size distribution across the 0.5-20 µm diameter size range. Measurements were conducted in an environment with a sufficiently low background to detect a patient's cough, enabling confident identification of aerosol. Phantom head control experiments for each procedure were performed under the same conditions as a comparison. Where aerosol was detected during a patient procedure, we assessed whether the size distribution could be explained by the non-salivary contaminated instrument source in the respective phantom head control procedure using a two-sided unpaired t-test (comparing the mode widths (log(σ)) and peak positions (DP,C)). The aerosol size distribution provided a robust fingerprint of aerosol emission from a source. 41 patients underwent fifteen different dental procedures. For nine procedures, no aerosol was detected above background. Where aerosol was detected, the percentage of procedure time that aerosol was observed above background ranged from 12.7% for ultrasonic scaling, to 42.9% for 3-in-1 air + water syringe. For ultrasonic scaling, 3-in-1 syringe use and surgical drilling, the aerosol size distribution matched the non-salivary contaminated instrument source, with no unexplained aerosol. High and slow speed drilling produced aerosol from patient procedures with different size distributions to those measured from the phantom head controls (mode widths log(σ)) and peaks (DP,C, p< 0.002) and, therefore, may pose a greater risk of salivary contamination. This study provides evidence for sources of aerosol generation during common dental procedures, enabling more informed evaluation of risk and appropriate mitigation strategies.

OBJECTIVE: To review guidance, included in written local UK National Health Service (NHS) organisation policies, on information provision and consent for the introduction of new invasive procedures- including surgeries, and devices (IPs/Ds). DESIGN: A qualitative documentary analysis of data on patient information provision and consent extracted from policies for the introduction of IP/Ds from NHS organisations in England and Wales. SETTING: NHS trusts in England and health boards in Wales, UK. PARTICIPANTS: Between December 2017 and July 2018, 150 acute trusts in England and 7 health boards in Wales were approached for their policies for the introduction of new IP/Ds. In total, 123 policies were received, 11 did not fit the inclusion criteria and a further policy was included from a trust website resulting in 113 policies included for review. RESULTS: From the 113 policies, 22 did not include any statements on informed consent/information provision or lacked guidance on the information to be provided to patients and were hence excluded. Consequently, 91 written local NHS policies were included in the final dataset. Within the guidance obtained, variation existed on disclosure of the procedure's novelty, potential risks, benefits, uncertainties, alternative treatments and surgeon's experience. Few policies stated that clinicians should discuss the existing evidence associated with a procedure. Additionally, while the majority of policies referred to patients needing written information, this was often not mandated and few policies specified the information to be included. CONCLUSIONS: Nearly a fifth of all the policies lacked guidance on information to be provided to patients. There was variability in the policy documents regarding what patients should be told about innovative procedures. Further research is needed to ascertain the information and level of detail appropriate for patients when considering innovative procedures. A core information set including patients' and clinicians' views is required to address variability around information provision/consent for innovative procedures.

INTRODUCTION: Robotic cholecystectomy (RC) is a recent innovation in minimally invasive gallbladder surgery. The IDEAL (idea, development, exploration, assessment, long-term study) framework aims to provide a safe method for evaluating innovative procedures. This study aimed to understand how RC was introduced, in accordance with IDEAL guidelines. METHODS: Systematic searches were used to identify studies reporting RC. Eligible studies were classified according to IDEAL stage and data were collected on general study characteristics, patient selection, governance procedures, surgeon/centre expertise, and outcome reporting. RESULTS: Of 1425 abstracts screened, 90 studies were included (5 case reports, 38 case series, 44 non-randomized comparative studies, and 3 randomized clinical trials). Sixty-four were single-centre and 15 were prospective. No authors described their work in the context of IDEAL. One study was classified as IDEAL stage 1, 43 as IDEAL 2a, 43 as IDEAL 2b, and three as IDEAL 3. Sixty-four and 51 provided inclusion and exclusion criteria respectively. Ethical approval was reported in 51 and conflicts of interest in 34. Only 21 reported provision of training for surgeons in RC. A total of 864 outcomes were reported; 198 were used in only one study. Only 30 reported a follow-up interval which, in 13, was 1 month or less. CONCLUSION: The IDEAL framework was not followed during the adoption of RC. Few studies were conducted within a research setting, many were retrospective, and outcomes were heterogeneous. There is a need to implement appropriate tools to facilitate the incremental evaluation and reporting of surgical innovation.

OBJECTIVE: Outcome selection and reporting in studies of novel surgical procedures and devices lacks standardisation, hindering safe and effective evaluation. A core outcome set (COS) to measure and report in all studies of surgical innovation is needed. We explored outcomes in a specific sample of innovative surgical device case studies to identify outcome domains specifically relevant to innovation to inform the development of a COS. DESIGN: A targeted review of 11 purposive selected case studies of innovative surgical devices. METHODS: Electronic database searches in PubMed (July 2018) identified publications reporting the introduction and evaluation of each device. Outcomes were extracted and categorised into domains until no new domains were conceptualised. Outcomes specifically relevant to evaluating innovation were further scrutinised. RESULTS: 112 relevant publications were identified, and 5926 outcomes extracted. Heterogeneity in study type, outcome selection and reporting was observed across surgical devices. Categorisation of outcomes was performed for 2689 (45.4%) outcomes into five broad outcome domains. Outcomes considered key to the evaluation of innovation (n=66; 2.5%) were further categorised as surgeon/operator experience (n=40; 1.5%), unanticipated events (n=15, 0.6%) and modifications (n=11; 0.4%). CONCLUSION: Outcome domains unique to evaluating innovative surgical devices have been identified. Findings have been combined with multiple other data sources relevant to the evaluation of surgical innovation to inform the development of a COS to measure and report in all studies evaluating novel surgical procedures/devices.

There are around 8,500 new cases of oral squamous cell carcinoma (SCC) diagnosed in the UK each year and the incidence appears to be increasing. Although surgical and non-surgical treatment options have improved significantly in the last few decades, five-year survival has not, with an average five-year survival of 56% in the UK. Providing patients have access, there are frequent opportunities for oral cancer screening by their general dental practitioner. We present two cases of SCC managed in our department, both of whom were referred following a protracted period of review in general dental practice, where the initial 'benign diagnoses' were not re-evaluated during this time. This delay can considerably impact on patient outcomes, including survival. We outline each patient's clinical course, and key learning points to help dental practitioners detect lesions that require prompt referral to the oral and maxillofacial service for urgent investigation.

BACKGROUND: In 2002 a pyrocarbon interphalangeal joint implant was granted Food and Drug Administration approval with limited evidence of effectiveness. It is important to understand device use and outcomes since this implant entered clinical practice in order to establish incremental evidence, appropriate study design and reporting. This systematic review summarised and appraised studies reporting pyrocarbon proximal interphalangeal joint arthroplasty. METHODS: Systematic review of MEDLINE, EMBASE, SCOPUS, Web of Science, BIOSIS, CINAHL and CENTRAL from inception to November 2020. All study designs reporting pyrocarbon proximal interphalangeal joint arthroplasty in humans were included. Data extracted included information about study characteristics, patient selection, regulatory (gaining research ethics approval) and governance issues (reporting of conflicting interests), operator and centre experience, technique description and outcome reporting. Descriptive and narrative summaries were reported. RESULTS: From 4316 abstracts, 210 full-text articles were screened. A total of 38 studies and 1434 (1-184) patients were included. These consisted of three case reports, 24 case series, 10 retrospective cohort studies and one randomised trial. Inclusion and exclusion criteria were stated in 25 (66%) studies. Most studies (n = 27, 71%) gained research ethics approval to be conducted. Six studies reported conflicting interests. Experience of operating surgeons was reported in nine (24%) and caseload volume in five studies. There was no consensus about the optimal surgical approach. Technical aspects of implant placement were reported frequently (n = 32) but the detail provided varied widely. Studies reported multiple, heterogenous outcomes. The most commonly reported outcome was range of motion (n = 37). CONCLUSIONS: This systematic review identified inconsistencies in how studies describing the early use and update of an innovative procedure were reported. Incremental evidence was lacking, risking the implant being adopted without robust evaluation. This review adds to evidence highlighting the need for more rigorous evaluation of how implantable medical devices are used in practice following licencing.

BACKGROUND: More stringent policies for addressing conflicts of interest have been implemented around the world in recent years. Considering the value of revisiting conflict of interest quality standards set by the International Patient Decision Aid Standards (IPDAS) Collaboration, we sought to review evidence relevant to 2 questions: 1) What are the effects of different strategies for managing conflicts of interest? and 2) What are patients' perspectives on conflicts of interest? METHODS: We conducted a narrative review of English-language articles and abstracts from 2010 to 2019 that reported relevant quantitative or qualitative research. RESULTS: Of 1743 articles and 118 abstracts identified, 41 articles and 2 abstracts were included. Most evidence on the effects of conflict of interest management strategies pertained only to subsequent compliance with the management strategy. This evidence highlighted substantial noncompliance with prevailing requirements. Evidence on patient perspectives on conflicts of interest offered several insights, including the existence of diverse views on the acceptability of conflicts of interest, the salience of conflict of interest type and monetary value to patients, and the possibility that conflict of interest disclosure could have unintended effects. We identified no published research on the effects of IPDAS Collaboration conflict of interest quality standards on patient decision making or outcomes. LIMITATIONS: Because we did not conduct a systematic review, we may have missed some evidence relevant to our review questions. In addition, our team did not include patient partners. CONCLUSIONS: The findings of this review have implications for the management of conflicts of interest not only in patient decision aid development but also in clinical practice guideline development, health and medical research reporting, and health care delivery.

OBJECTIVES: Little is known about how innovative surgical procedures are introduced and discussed with patients. This qualitative study aimed to explore perspectives on information provision and consent prior to innovative surgical procedures. DESIGN: Qualitative study involving semi-structured interviews. Interviews were audio recorded, transcribed and analysed thematically. PARTICIPANTS: 42 interviews were conducted (26 surgeons and 16 governance representatives). SETTING: Surgeons and governance representatives recruited from various surgical specialties and National Health Service (NHS) Trusts across England, UK. RESULTS: Participants stated that if a procedure was innovative, patients should be provided with additional information extending beyond that given during routine surgical consultations. However, difficulty defining innovation had implications for whether patients were informed about novel components of surgery and how the procedure was introduced (ie, as part of a research study, trust approval or in routine clinical practice). Furthermore, data suggest surgeons found it difficult to establish what information is essential and how much detail is sufficient, and governance surrounding written and verbal information provision differed between NHS Trusts. Generally, surgeons believed patients held a view that 'new' was best and reported that managing these expectations could be difficult, particularly if patient views aligned with their own. CONCLUSIONS: This study highlights the challenges of information provision and obtaining informed consent in the context of innovative surgery, including establishing if and how a procedure is truly innovative, determining the key information to discuss with patients, ensuring information provision is objective and balanced, and managing patient expectations and preferences. This suggests that surgeons may require support and training to discuss novel procedures with patients. Further work should capture consultations where new procedures are discussed with patients and patients' views of these information exchanges.

INTRODUCTION: Innovation is key to improving outcomes in healthcare. Innovative pharmaceutical products undergo rigorous phased research evaluation before they are introduced into practice. The introduction of innovative invasive procedures and devices is much less rigorous and phased research, including randomised controlled trials, is not always undertaken. While the innovator (usually a surgeon) may introduce a new or modified procedure/device within the context of formal research, they may also be introduced by applying for local National Health Service (NHS) organisation approval alone. Written policies for the introduction of new procedures and/or devices often form part of this local clinical governance infrastructure; however, little is known about their content or use in practice. This study aims to systematically investigate how new invasive procedures and devices are introduced in NHS England and Wales. METHODS AND ANALYSIS: An in-depth analysis of written policies will be undertaken. This will be supplemented with interviews with key stakeholders. All acute NHS trusts in England and Health Boards in Wales will be systematically approached and asked to provide written policies for the introduction of new invasive procedures and devices. Information on the following will be captured: (1) policy scope, including when new procedures should be introduced within a formal research framework; (2) requirements for patient information provision; (3) outcome reporting and/or monitoring. Data will be extracted using a standardised form developed iteratively within the study team. Semistructured interviews with medical directors, audit and governance leads, and surgeons will explore views regarding the introduction of new invasive procedures into practice, including knowledge of and implementation of current policies. ETHICS AND DISSEMINATION: In-depth analysis of written policies does not require ethics approval. The University of Bristol Ethics Committee (56522) approved the interview component of the study. Findings from this work will be presented at appropriate conferences and will be published in peer-reviewed journals.

INTRODUCTION: Transoral robotic surgery (TORS) has been adopted in some parts of the world as an innovative approach to the resection of oropharyngeal tumours. The development, details and outcomes of early-to-later phase evaluation of this technique and the quality of evidence to support its adoption into practice have hitherto not been summarised. The aim of this review is to identify and summarise the early and later phase studies of, and evidence for, TORS and to understand how early phase studies report intervention development, governance procedures and selection and reporting of outcomes to optimise methods for using the Idea, Development, Exploration, Assessment, Long-term follow-up (IDEAL) framework for surgical innovation that informs evidence-based practice. The protocol has been written in line with the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols checklist. METHODS AND ANALYSIS: Electronic searches in OVID SP versions of Medline and EMBASE, the Cochrane Central Register of Controlled Trials and the Cochrane Database of Systematic Reviews from the start of indexing to 30 April 2017 will identify studies reporting TORS. At least two independent researchers will identify studies for inclusion. Two researchers will extract data from each paper. Studies will be categorised into IDEAL stages of study design from 'pre-IDEAL' to randomised controlled trials (stage 3). Data will be collected about the (1) novel intervention and criteria for modification, (2) governance arrangements and patient information provision, (3) outcome domains selected and reported and (4) quality of study design, conduct and reporting. Descriptive statistics and a narrative synthesis will be presented. ETHICS AND DISSEMINATION: The results of this systematic review will be presented at relevant conferences. The methods will be used to inform future reviews exploring other novel surgical innovations. The findings will be published in a peer-reviewed journal. This study does not require ethical approval.
