RESUMO

BACKGROUND: Breast cancer screening attendance in the UK has fallen, and London has the lowest uptake nationally. This study tested the impact of a behavioural science-informed reminder SMS, and animated video intervention on screening uptake. METHODS: This three-armed randomised controlled trial took place in two screening services in London (each service operated across a range of static sites such as hospitals, and mobile sites). We included participants who were registered with GP as female, aged 50-70 years, and not screened in the past 3 years. We excluded those who had opted out of screening messages or were in care. Participants were assigned into three groups via the final two digits of their NHS number (ratio 34:33:33): control group (received usual care reminder), behavSMS group (behavioural science-informed SMS reminder addressing reducing negative emotions and information on health consequences), or behavSMS+video group (behavioural SMS plus link to animation). Researchers were masked to allocation. The SMS and video were co-designed with stakeholders using the Behaviour Change Wheel. Invitation processes changed during the COVID-19 pandemic, and therefore, we did separate analyses for those receiving a timed appointment (n=9027), and an open invitation to book an appointment (n=25 020). Messages were sent 7 days and 1 day before the appointment, plus 7 days after the open invitation letter. Group differences in the primary outcome of attendance within 3 months of invitation (and secondary outcome of booking for open invites) were assessed using χ2, and logistic regression controlling for age, ethnicity, deprivation, and first invitation. This trial is registered with ClinicalTrials.gov, NCT05395871. FINDINGS: Recruitment took place between July 18, and Oct 21, 2022. For timed invitations, 3094 participants were assigned to the control group, 2952 to the behavSMS group, and 2981 to the behavSMS+video group. For open invitations groups sizes were 8654, 8095, and 8271 respectively. Median age was 59 years for participants who received a timed appointment, and 58 years for those who received an open invitation. There were no attendance differences for timed appointments (intention-to-treat analysis): 71·9% (2225/3094) in control group; 69·9% (2064/2952) in behavSMS group; 71·7% (2137/2981) in behavSMS+video group (χ2(2)=3·47, p=0·176), even when controlling for covariates. There were no attendance differences for open invitations either: 7·4% (4104/8654) in control group, 8·3% (3909/8095) in behavSMS group, 48·1% (3978/8271) in behavSMS+video (χ2(2)=1·40, p=0·497), including when controlling for covariates. However, in the per-protocol analysis (of those with valid mobile numbers), intervention groups were more likely to book an appointment: 44·7% (3238/7274) in control group, 46·3% (3121/6744) in behavSMS group, and 46·3% (3199/6910) in behavSMS+video group (χ2(2)=6·01, p=0·050). INTERPRETATION: Despite positive stakeholder feedback during co-design, the SMS or SMS+video interventions did not increase breast screening attendance compared with the usual SMS reminder. A limitation is that only 5·8% participants followed the video link. Links within SMS are unlikely to be an effective way to disseminate video content, and alternative options are being explored.

RESUMO

BACKGROUND: Poor handovers between hospital and primary care threaten safe discharges, with elderly and frail patients most at risk of harm. Using Behavioural Science we explored influences and identified relevant behaviour change techniques (BCTs) to improve written handovers and safety during discharge. METHODS: We conducted two qualitative studies: (1) ethnographic observations (>80 h) collected by five researchers in five purposively sampled clinical areas of a London teaching hospital, investigating routine work and interactions of hospital staff involved in discharges; and (2) 12 semi-structured interviews with hospital staff involved in discharge exploring influences on preparations of written handovers. Written consent was sought from clinical leads for ethnographic observations and from interview participants. Ethnographic fieldnotes and interview transcripts were thematically analysed using inductive and deductive approaches, respectively. Study findings were triangulated to identify key influences, mapped onto the Theoretical Domains Framework (TDF). We identified appropriate BCTs to address observed influences within each TDF domain using the Theory and Techniques Tool. Health-care workers (n=15), patients (n=2) and carers (n=2) selected and designed an intervention to improve written handovers in two workshops. Hospital workshop participants were involved with preparing written discharge handovers. Public participants had either recently been discharged from hospital or cared for someone recently discharged, including patients from groups especially vulnerable during discharge. FINDINGS: Triangulation of study findings generated 11 key influences on preparations of written handovers within five TDF domains: knowledge (eg, lack of awareness of guidelines), skills (staff experience), social or professional role and identity (effective communication), environmental context and resources (working patterns), and social influences (lack of feedback). 14 BCTs were identified to address these influences, including behavioural rehearsal or practice, instruction on how to perform a behaviour, and social support (practical). Workshop participants selected and designed a multifaceted educational intervention to improve written handovers. INTERPRETATION: The quality of handover documentation prepared by hospital staff for primary care teams is affected by influences from multiple domains, requiring a multifaceted approach to improve handovers. Although only based on findings from one hospital, the designed intervention should be tested in clinical settings with key stakeholders, including primary care staff, to evaluate impact on quality of written handovers and patient safety.

RESUMO

OBJECTIVES: Survivorship encompasses the physical, psychological, social, functional, and economic experience of a living with a chronic condition for both the patient and their caregiver. It is made up of nine distinct domains and remains understudied in nononcological pathologies, including infrarenal abdominal aortic aneurysmal disease (AAA). This review aims to quantify the extent to which existing AAA literature addresses the burden of survivorship. METHODS: The MEDLINE, EMBASE, and PsychINFO databases were searched from 1989 through September 2022. Randomized controlled trials, observational studies, and case series were included. Eligible studies had to detail outcomes related to survivorship in patients with AAA. Owing to the heterogeneity between studies and outcomes, no meta-analysis was conducted. Study quality was assessed with specific risk of bias tools. RESULTS: A total of 158 studies were included. Of these, only five (treatment complications, physical functioning, comorbidities, caregivers, and mental health) of the nine domains of survivorship have been studied previously. The available evidence is of variable quality; most studies display a moderate to high risk of bias, are of an observational study design, are based within a limited number of countries, and consist of an insufficient follow-up period. The most frequent complication after EVAR was endoleak. EVAR is associated with poorer long-term outcomes compared with open surgical repair in most studies retrieved. EVAR showed better outcomes in regard to physical functioning in the short term, but this advantage was lost in the long term. The most common comorbidity studied was obesity. No significant differences were found between open surgical repair and EVAR in terms of impact on caregivers. Depression is associated with various comorbidities and increased the risk of a nonhospital discharge. CONCLUSIONS: This review highlights the absence of robust evidence regarding survivorship in AAA. As a result, contemporary treatment guidelines rely on historic quality-of-life data that are narrow in scope and nonrepresentative of contemporary clinical practice. As such, there is an urgent need to reevaluate the aims and methodology associated with traditional quality-of-life research moving forward.

RESUMO

BACKGROUND: Breast cancer screening is estimated to save 1300 lives annually in the United Kingdom. Despite this, uptake of invitations has fallen over the past decade. Behavioural science-informed interventions addressing the determinants of attendance behaviour have shown variable effectiveness. This may be due to the narrow repertoire of techniques trialled, and the difficulties of implementation at a population-scale. The aim of this study is to evaluate the impact on breast screening uptake of a novel behavioural video intervention which can contain more complex combinations of behavioural change techniques. METHODS: A 3-armed randomised controlled trial will be undertaken in London comparing the impact of (1) the usual care SMS reminder, to (2) a behavioural plain text SMS reminder and (3) a novel video sent as a link within the behavioural plain text SMS reminder. A total of 8391 participants (2797 per group) will be allocated to one of the three trial arms using a computer randomisation process, based upon individuals' healthcare identification numbers. The novel video has been co-designed with a diverse range of women to overcome the barriers faced by underserved communities and the wider population. The behavioural SMS content has also been co-designed through the same process as the video. Messages will be sent through the current reminder system used by the London screening programmes, with reminders 7 days and 2 days prior to a timed appointment. The primary outcome is attendance at breast cancer screening within 3 months of the initial invitation. Secondary outcomes will include evaluating the impact of each message amongst socio-demographic groups and according to the appointment type e.g. first invitation or recall. DISCUSSION: In addition to general declining trends in attendance, there is also concern of increasing healthcare inequalities with breast cancer screening in London. The current novel intervention, designed with underserved groups and the general population, incorporates several behavioural techniques to overcome the barriers to attendance. Understanding its potential impact in a real-world setting therefore may provide significant information on how to address reducing attendance and healthcare disparities. TRIAL REGISTRATION: This study was registered on ClinicalTrials.gov ( NCT05395871 ) on the 27th May 2022.

RESUMO

INTRODUCTION: The aim of this study was to identify factors associated with primary graft patency 1 year following open lower limb revascularisation (LLR) at a tertiary referral vascular service. METHODS: A retrospective analysis of patients undergoing infra-inguinal bypass surgery between January 2016 and May 2017 at a tertiary vascular centre (St Mary's Hospital, London) was performed. Data regarding patient demographics, comorbidities, type of operation and post-operative anti-thrombotic strategy were collected. Quality of run-off score was assessed from pre-operative imaging. RESULTS: Seventy-seven cases were included in the analysis. Overall, the primary patency rate at 1-year was 63.6% (n = 49/77) and the secondary patency rate was 67.5% (n = 52/77). Independent variables with statistically significant inferior patency rates at 1-year were (1) bypasses with below knee targets (p = 0.0096), (2) chronic limb threatening ischaemia indication (p = 0.038), (3) previous ipsilateral revascularisation (p < 0.001) and (4) absence of hypertension history (p = 0.041). There was also a trend towards significance for American Society of Anesthesiologists (ASA) grade (p = 0.06). Independent variables with log-rank test p values of <0.1 were included in a Cox proportional hazards model. The only variable with a statistically significant impact on primary patency rates was previous open or endovascular ipsilateral revascularisation (HR 2.44 (1.04-5.7), p = 0.04). CONCLUSION: At 1-year follow-up, previous ipsilateral revascularisation was the most significant factor in affecting patency rates. Patients in this subgroup should therefore be deemed high-risk, which should be reflected in the informed consent and peri-operative management.

RESUMO

OBJECTIVES: The PREDICT study aimed to determine how the COVID-19 pandemic affected surgical services and surgical patients and to identify predictors of outcomes in this cohort. BACKGROUND: High mortality rates were reported for surgical patients with COVID-19 in the early stages of the pandemic. However, the indirect impact of the pandemic on this cohort is not understood, and risk predictors are yet to be identified. METHODS: PREDICT is an international longitudinal cohort study comprising surgical patients presenting to hospital between March and August 2020, conducted alongside a survey of staff redeployment and departmental restructuring. A subgroup analysis of 3176 adult emergency patients, recruited by 55 teams across 18 countries is presented. RESULTS: Among adult emergency surgical patients, all-cause in-hospital mortality (IHM) was 3.6%, compared to 15.5% for those with COVID-19. However, only 14.1% received a COVID-19 test on admission in March, increasing to 76.5% by July.Higher Clinical Frailty Scale scores (CFS >7 aOR 18.87), ASA grade above 2 (aOR 4.29), and COVID-19 infection (aOR 5.12) were independently associated with significantly increased IHM.The peak months of the first wave were independently associated with significantly higher IHM (March aOR 4.34; April aOR 4.25; May aOR 3.97), compared to non-peak months.During the study, UK operating theatre capacity decreased by a mean of 63.6% with a concomitant 27.3% reduction in surgical staffing. CONCLUSION: The first wave of the COVID-19 pandemic significantly impacted surgical patients, both directly through co-morbid infection and indirectly as shown by increasing mortality in peak months, irrespective of COVID-19 status.Higher CFS scores and ASA grades strongly predict outcomes in surgical patients and are an important risk assessment tool during the pandemic.

RESUMO

Whilst breast cancer screening has been implemented in many countries, uptake is often suboptimal. Consequently, several interventions targeting non-attendance behaviour have been developed. This systematic review aims to appraise the successes of interventions, identifying and comparing the specific techniques they use to modify health behaviours. A literature search (PROSPERO CRD42020212090) between January 2005 and December 2020 using PubMed, Medline, PsycInfo, EMBASE and Google Scholar was conducted. Studies which investigated patient-facing interventions to increase attendance at breast cancer screening appointments were included. Details regarding the intervention delivery, theoretical background, and contents were extracted, as was quantitative data on the impact on attendance rates, compared to control measures. Interventions were also coded using the Behavioural Change Techniques (BCT) Taxonomy. In total fifty-four studies, detailing eighty interventions, met the inclusion criteria. Only 50% of interventions reported a significant impact on screening attendance. Thirty-two different BCTs were used, with 'prompts/cues' the most commonly incorporated (77.5%), however techniques from the group 'covert learning' had the greatest pooled effect size 0.12 (95% CI 0.05-0.19, P < 0·01, I2 = 91.5%). 'Problem solving' was used in the highest proportion of interventions that significantly increased screening attendance (69.0%). 70% of the interventions were developed using behavioural theories. These results show interventions aimed at increasing screening uptake are often unsuccessful. Commonly used approaches which focus upon explaining the consequences of not attending mammograms were often ineffective. Problem solving, however, has shown promise. These techniques should be investigated further, as should emerging technologies which can enable interventions to be feasibly translated at a population-level.

RESUMO

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.

RESUMO

BACKGROUND: The COVID-19 vaccination roll-out continues to grow at significant pace around the world. There is, however, growing concern regarding vaccine hesitancy amongst Black, Asian and Minority Ethnic (BAME) populations. Such inequalities have the potential for exposing, an already at-risk population, further. Whilst the COVID-19 vaccination programme is in its infancy, influenza programmes have been undertaken for over 50 years, and may provide invaluable insights. In this commentary, we aim to examine the lessons from influenza vaccinations, and how this can help reduce inequalities with COVID-19 vaccinations. MAIN TEXT: Several factors have been associated with both seasonal and pandemic influenza vaccine hesitancy amongst BAME groups. One of the most prevalent barriers in both types of immunisation programmes is the mistrust of medical organisations. This is often a multi-faceted issue, with previous negative healthcare discrimination, and historical unethical practices contributing towards this scepticism. This mistrust, however, is predominantly aimed towards healthcare systems, as opposed to individual physicians. In fact, physician endorsement is often a strong driver to vaccination, with Black patients who receive this support 8 times more likely to receive seasonal influenza vaccination. On the other hand, with H1N1 pandemic influenza vaccination, social norms or community influence, was an important determinant. In both seasonal and pandemic immunisation programmes, a significant amount of concern regarding side-effects, including misinformation, was reported amongst BAME groups. CONCLUSIONS: The use of community-based approaches, with local advocacy, has the potential to counteract misinformation, and concerns regarding side-effects. Moreover, using consistent physician endorsement not only in media campaigns but also through messaging would potentially help to address longstanding healthcare mistrust amongst minority ethnic groups. Close attention regarding how the vaccination programme, and the health policies introduced as a consequence, affect BAME communities in order to prevent widening inequalities in the future.

RESUMO

BACKGROUND: The use of face masks remains contentious, with international variation in practice. Their prevalence in the UK, is likely to increase due to new legislation. Clear information regarding the appropriate use of masks is needed, to ensure compliance with policies to reduce transmission of COVID-19. We aimed to assess the impact of visual representations of guidance, or infographics, upon the knowledge of appropriate face mask usage in a representative UK cohort. METHODS: Adult patients were recruited to this randomised internet-based questionnaire study during the 12-14 May 2020 from across the UK. Respondents viewed one of five public health stimuli regarding the use of face masks, or no stimulus. The groups accessed aids by the European Centre for Disease Control (EUCDC), World Health Organisation (WHO), Singaporean Ministry of Health (SMOH), text from the UK government (UK Gov), or an infographic designed by the Behavioural Insights Team (BIT). The primary outcome was to evaluate the effect of each infographic upon participants' recall of face mask technique, sentiments and willingness to wear a face covering. Secondary outcomes included the effect of symptomology and socio-demographic factors. RESULTS: 4099 respondents were randomised (1009 control, 628 EUCDC, 526 WHO, 639 SMOH, 661 UKGOV and 606 BIT). Stimuli from the WHO, SMOH and BIT demonstrated significantly higher average recall scores compared to the controls (7.40 v. 7.38 v. 7.34 v. 6.97, P < 0.001). BIT's stimulus led to the highest confidence about mask-wearing (87%). Only 48.2% of the cohort felt stimuli reduced anxiety about COVID-19. However, willingness to use a mask was high, (range 84 to 88%). CONCLUSIONS: To ensure the appropriate use of masks, as mandated by UK law, guidance must provide sufficient information, yet remain understandable. Infographics can aid the recall of correct mask techniques by highlighting salient steps and reducing cognitive burden. They have also demonstrated greater trustworthiness than text-only guidance. The effect of infographics upon COVID-19-related anxiety was poor, and they should be further developed to address this sentiment. A willingness to wear face masks has, however, been demonstrated.

RESUMO

BACKGROUND: Peritoneal cytology has been used as a part of the cancer staging of gastric cancer patients. The primary aim of this systematic review was to evaluate the value of peritoneal cytology as part of the staging of gastric cancer and survival prediction. The second aim was to establish if positive cytology may be modified by neoadjuvant therapy, to improve prognosis. METHODS: An electronic literature search was performed using Embase, Medline, Web of Science, and Cochrane library databases up to January 2016. The logarithm of the hazard ratio (HR) with 95% confidence intervals (CI) was used as the primary summary statistic. Comparative studies were used, and the outcome measure was survival in three groups: (1) positive versus negative cytology at staging laparoscopy immediately preceding surgery; (2) effect of neoadjuvant therapy on cytology and survival; and (3) positive cytology in the absence of macroscopic peritoneal disease was compared with obvious macroscopic peritoneal disease. RESULTS: Pooled analysis demonstrated that positive cytology was associated with significantly reduced overall survival (HR, 3.46; 95% CI, 2.77-4.31; P < 0.0001). Interestingly, negative cytology following neoadjuvant chemotherapy was associated with significantly improved overall survival (HR, 0.42; 95% CI, 0.31-0.57; P < 0.0001). The absence of macroscopic peritoneal disease with positive cytology was associated with significantly improved overall survival (HR, 0.64; 95% CI, 0.56-0.73; P < 0.0001). CONCLUSION: This study suggests that patients with initial positive cytology may have a good prognosis following neoadjuvant treatment if the cytology results change to negative after treatment.

RESUMO

BACKGROUND: Gastrointestinal cancers constitute the third most common cancers worldwide. Tumor markers have long since been used in the postoperative surveillance of these malignancies; however, the true value in clinical practice remains undetermined. OBJECTIVE: This study aimed to evaluate the clinical utility of three tumor markers in colorectal and esophagogastric cancer. METHODS: A systematic review of the literature was undertaken to elicit the sensitivity, specificity, statistical heterogeneity and ability to predict recurrence and metastases for carcinoembryonic antigen (CEA), cancer antigen (CA) 19-9 and CA125. European surgeons were surveyed to assess their current practice and the characteristics of tumor markers they most valued. Data from the included studies and survey were combined in a cost-benefit trade-off analysis to assess which tumor markers are of most use in clinical practice. RESULTS: Diagnostic sensitivity and specificity were ranked the most desirable characteristics of a tumor marker by those surveyed. Overall, 156 studies were included to inform the cost-benefit trade-off. The cost-benefit trade-off showed that CEA outperformed both CA19-9 and CA125, with lower financial cost and a higher sensitivity, and diagnostic accuracy for metastases at presentation (area under the curve [AUC] 0.70 vs. 0.61 vs. 0.46), as well as similar diagnostic accuracy for recurrence (AUC 0.46 vs. 0.48). CONCLUSIONS: Cost-benefit trade-off analysis identified CEA to be the best performing tumor marker. Further studies should seek to evaluate new tumor markers, with investigation tailored to factors that meet the requirements of practicing clinicians.

RESUMO

BACKGROUND: Acute appendicitis is the most common surgical emergency and can represent a challenging diagnosis, with a negative appendectomy rate as high as 20 %. This review aimed to evaluate the clinical utility of individual biomarkers in the diagnosis of appendicitis and appraise the quality of these studies. METHODS: A systematic review of the literature between January 2000 and September 2015 using of PubMed, OvidMedline, EMBASE and Google Scholar was conducted. Studies in which the diagnostic accuracy, statistical heterogeneity and predictive ability for severity of several biomarkers could be elicited were included. Information regarding costs and process times was retrieved from the regional laboratory. European surgeons blinded to these reviews were independently asked to rank which characteristics of biomarkers were most important in acute appendicitis to inform a cost-benefit trade-off. Sensitivity testing and the QUADAS-2 tool were used to assess the robustness of the analysis and study quality, respectively. RESULTS: Sixty-two studies met the inclusion criteria and were assessed. Traditional biomarkers (such as white cell count) were found to have a moderate diagnostic accuracy (0.75) but lower costs in the diagnosis of acute appendicitis. Conversely, novel markers (pro-calcitonin, IL 6 and urinary 5-HIAA) were found to have high process-related costs including analytical times, but improved diagnostic accuracy. QUADAS-2 analysis revealed significant potential biases in the literature. CONCLUSION: When assessing biomarkers, an appreciation of the trade-offs between the costs and benefits of individual biomarkers is needed. Further studies should seek to investigate new biomarkers and address concerns over bias, in order to improve the diagnosis of acute appendicitis.

RESUMO

Gastric cancer is the fifth most common cancer and the second most common cause of cancer-related death worldwide. The aim of this review was to evaluate the effect of gastric cancer screening on the stage at diagnosis and survival from disease. A systematic review of the literature between January 1995 and December 2014 was performed. Studies that compared screened versus nonscreened populations for the diagnosis of gastric cancer and included the stage at diagnosis were analyzed. The QUADAS-2 and the ROBANS tools were used to assess the quality of the studies. A total of 11 studies from the Far East comprising 4039 participants in the screened and 6635 in the nonscreened groups were included. Screening was associated with a significant increase in the detection of early gastric cancer (EGC) [pooled odds ratio (POR)=3.90; 95% confidence interval (CI), 3.01-5.06; P<0.0001] and reduction in the incidence of advanced gastric cancer (POR=0.27; 95% CI, 0.20-0.35; P<0.0001). Furthermore, screening improved the 5-year survival significantly (hazard ratio=0.56; 95% CI, 0.48-0.66; P<0.0001). About 73% of the screened patients were found to have EGC compared with 43% of the nonscreened patients. About 8% of the screened patients were found to have advanced gastric cancer compared with 54% of the nonscreened patients. Screening for gastric cancer is useful in detecting asymptomatic patients with EGC in high-prevalence areas. This in turn increases the number of treatable cancers and improves the 5-year survival. There is a need for the development and the validation of alternative risk-stratification tools in low-incidence areas to allow for similar benefits.

RESUMO

Unequivocal international guidelines regarding the diagnosis and management of patients with acute appendicitis are lacking. The aim of the consensus meeting 2015 of the EAES was to generate a European guideline based on best available evidence and expert opinions of a panel of EAES members. After a systematic review of the literature by an international group of surgical research fellows, an expert panel with extensive clinical experience in the management of appendicitis discussed statements and recommendations. Statements and recommendations with more than 70 % agreement by the experts were selected for a web survey and the consensus meeting of the EAES in Bucharest in June 2015. EAES members and attendees at the EAES meeting in Bucharest could vote on these statements and recommendations. In the case of more than 70 % agreement, the statement or recommendation was defined as supported by the scientific community. Results from both the web survey and the consensus meeting in Bucharest are presented as percentages. In total, 46 statements and recommendations were selected for the web survey and consensus meeting. More than 232 members and attendees voted on them. In 41 of 46 statements and recommendations, more than 70 % agreement was reached. All 46 statements and recommendations are presented in this paper. They comprise topics regarding the diagnostic work-up, treatment indications, procedural aspects and post-operative care. The consensus meeting produced 46 statements and recommendations on the diagnostic work-up and management of appendicitis. The majority of the EAES members supported these statements. These consensus proceedings provide additional guidance to surgeons and surgical residents providing care to patients with appendicitis.

RESUMO

BACKGROUND: The key to the digital leveling-up strategy of the National Health Service is the development of a digitally proficient leadership. The National Health Service Digital Academy (NHSDA) Digital Health Leadership program was designed to support emerging digital leaders to acquire the necessary skills to facilitate transformation. This study examined the influence of the program on professional identity formation as a means of creating a more proficient digital health leadership. OBJECTIVE: This study aims to examine the impact of the NHSDA program on participants' perceptions of themselves as digital health leaders. METHODS: We recruited 41 participants from 2 cohorts of the 2-year NHSDA program in this mixed methods study, all of whom had completed it >6 months before the study. The participants were initially invited to complete a web-based scoping questionnaire. This involved both quantitative and qualitative responses to prompts. Frequencies of responses were aggregated, while free-text comments from the questionnaire were analyzed inductively. The content of the 30 highest-scoring dissertations was also reviewed by 2 independent authors. A total of 14 semistructured interviews were then conducted with a subset of the cohort. These focused on individuals' perceptions of digital leadership and the influence of the course on the attainment of skills. In total, 3 in-depth focus groups were then conducted with participants to examine shared perceptions of professional identity as digital health leaders. The transcripts from the interviews and focus groups were aligned with a previously published examination of leadership as a framework. RESULTS: Of the 41 participants, 42% (17/41) were in clinical roles, 34% (14/41) were in program delivery or management roles, 20% (8/41) were in data science roles, and 5% (2/41) were in "other" roles. Interviews and focus groups highlighted that the course influenced 8 domains of professional identity: commitment to the profession, critical thinking, goal orientation, mentoring, perception of the profession, socialization, reflection, and self-efficacy. The dissertation of the practice model, in which candidates undertake digital projects within their organizations supported by faculty, largely impacted metacognitive skill acquisition and goal orientation. However, the program also affected participants' values and direction within the wider digital health community. According to the questionnaire, after graduation, 59% (24/41) of the participants changed roles in search of more prominence within digital leadership, with 46% (11/24) reporting that the course was a strong determinant of this change. CONCLUSIONS: A digital leadership course aimed at providing attendees with the necessary attributes to guide transformation can have a significant impact on professional identity formation. This can create a sense of belonging to a wider health leadership structure and facilitate the attainment of organizational and national digital targets. This effect is diminished by a lack of locoregional support for professional development.

RESUMO

Barcode medication administration (BCMA) technology can improve patient safety by using scanning technology to ensure the right drug and dose are given to the right patient. Implementation can be challenging, requiring adoption of different workflows by nursing staff. In one London National Health Service trust scanning rates were lower than desired at around 0-20% of doses per ward. Our objective was to encourage patient safety behaviours in the form of medication scanning through implementation of a feedback intervention. This was informed by behavioural science, codesigned with nurses and informed by known barriers to use. Five wards were selected to trial the intervention over an 18-week period beginning August 2021. The remaining 14 hospital wards acted as controls. Intervention wards had varying uptake of BCMA at baseline and represented a range of specialties. A bespoke feedback intervention comprising three behavioural science constructs (gamification, the messenger effect and framing) was delivered to each intervention ward each week. A linear difference-in-difference analysis was used to evaluate the impact of our intervention on scan rates, both for the overall 18-week period and at two weekly intervals within this timeframe. We identified a 23.1 percentage point increase in medication scan rates (from an average baseline of 15.0% to 38.1%) on the intervention wards compared with control (p<0.001) following implementation of the intervention. Feedback had most impact in the first 6 weeks, with an initial percentage point increase of 26.3 (p<0.001), which subsequently plateaued. Neither clinical specialty nor number of beds on each ward were significant factors in our models. Our study demonstrated that a feedback intervention, codesigned with end users and incorporating behavioural science constructs, can lead to a significant increase in the adoption of BCMA scanning.

RESUMO

Surgery is a substantial contributor to healthcare-related emissions. Despite a drive to improve sustainability, few interventions have been adopted. Stakeholder engagement is considered a key barrier to implementation. This study aimed to determine the attitudes and beliefs of the perioperative staff and the public regarding sustainability initiatives in surgery, and whether differences exist between the two groups. Materials and Methods: Separate validated healthcare professional and public questionnaires were developed using a stepwise process. A systematic review was undertaken using Medline, Embase and Cochrane to identify key domains pertaining to sustainability and ensure content validity. Initial questionnaires were developed and refined using an iterative process of feedback from focus groups. Psychometric validation was conducted to remove question ambiguity. The final validated questionnaire was distributed to perioperative staff and the public using a multimodal approach involving online tools and in person. Results: Only 37.1% of perioperative staff reported the implementation of sustainability initiatives in their departments. Yet, staff (45.7%) and the public (48.2%) somewhat agreed that sustainability should influence a surgeon's procedural decision-making. Insufficient staff education regarding sustainability was a potential cause for the lack of adoption, with 71.4% reporting they had no formal training. Moreover, discrepancies in the perceived importance of sustainability may have contributed. Staff and the public agreed that outcomes (38.6 vs. 42.7%, P=0.767) and surgeon experience with a technique (28.6 vs. 40.0%, P=0.082) were more important than sustainability. However, 40.9% of the public did not consider operative time an important factor compared to sustainability, while 45.7% of staff would only tolerate procedures 25% longer. Conclusions: Engaging stakeholders is central to implementing long-term environmentally sustainable initiatives in surgery without compromising patient outcomes. More work is needed to understand the relative trade-offs considered by perioperative staff and the public, as well as provide both groups with more pertinent education on ecological outcomes.

RESUMO

OBJECTIVE: To systematically evaluate interventions designed to improve the sustainability of surgical practice with respect to their environmental and financial impact. BACKGROUND: Surgery contributes significantly to emissions attributed to healthcare due to its high resource and energy use. Several interventions across the operative pathway have, therefore, been trialed to minimize this impact. Few comparisons of the environmental and financial effects of these interventions exist. MATERIALS AND METHODS: A search of studies published up to 2nd February 2022 describing interventions to increase surgical sustainability was undertaken. Articles regarding the environmental impact of only anesthetic agents were excluded. Data regarding environmental and financial outcomes were extracted with a quality assessment completed dependent upon the study design. RESULTS: In all, 1162 articles were retrieved, of which 21 studies met inclusion criteria. Twenty-five interventions were described, which were categorized into five domains: 'reduce and rationalize', 'reusable equipment and textiles', 'recycling and waste segregation', 'anesthetic alternatives', and 'other'. Eleven of the 21 studies examined reusable devices; those demonstrating a benefit reported 40-66% lower emissions than with single-use alternatives. In studies not showing a lower carbon footprint, the reduction in manufacturing emissions was offset by the high environmental impact of local fossil fuel-based energy required for sterilization. The per use monetary cost of reusable equipment was 47-83% of the single-use equivalent. CONCLUSIONS: A narrow repertoire of interventions to improve the environmental sustainability of surgery has been trialed. The majority focuses on reusable equipment. Emissions and cost data are limited, with longitudinal impacts rarely investigated. Real-world appraisals will facilitate implementation, as will an understanding of how sustainability impacts surgical decision-making.

RESUMO

BACKGROUND: The increasing use of mobile messaging within healthcare, poses challenges for screening programmes, which involve communicating with large, diverse populations. This modified Delphi study aimed to create guidance regarding the use of mobile messaging for screening programmes, to facilitate greater, and equitable screening uptake. METHODS: Initial recommendations were derived from a literature review, expert scoping questionnaire, public consultation, and discussion with relevant national organisations. Experts from the fields of public health, screening commissioning, industry and academia voted upon the importance and feasibility of these recommendations across two consensus rounds, using a 5-point Likert scale. Items reaching consensus, defined a priori at 70%, on importance and feasibility formed 'core' recommendations. Those reaching this threshold on importance only, were labelled 'desirable'. All items were subsequently discussed at an expert meeting to confirm suitability. FINDINGS: Of the initial 101 items, 23 reached consensus regarding importance and feasibility. These 'core' items were divided across six domains: message content, timing, delivery, evaluation, security, and research considerations. 'Core' items such as explicitly specifying the sender and the role of patient involvement in development of screening message research had the highest agreement. A further 17 'desirable' items reached consensus regarding importance, but not feasibility, including the integration into GP services to enable telephone verification. INTERPRETATION: These findings forming national guidance for services, will enable programmes to overcome implementation challenges and facilitate uptake of screening invitations. By providing a list of desirable items, this study provides areas for future consideration, as technological innovation in messaging continues to grow.
