Managing the risks associated with technological disruption in the road transport system: a control structure modelling approach. ERGONOMICS 2024; 67:498-514. [PMID: 37381733 DOI: 10.1080/00140139.2023.2226850] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/10/2022] [Accepted: 06/11/2023] [Indexed: 06/30/2023]
Abstract
Road transport is experiencing disruptive change from new first-of-a-kind technologies. While such technologies offer safety and operational benefits, they also pose new risks. It is critical to proactively identify risks during the design, development and testing of new technologies. The Systems Theoretic Accident Model and Processes (STAMP) method analyses the dynamic structure in place to manage safety risks. This study applied STAMP to develop a control structure model for emerging technologies in the Australian road transport system and identified control gaps. The control structure shows the actors responsible for managing risks associated with first-of-a-kind technologies and the existing control and feedback mechanisms. Gaps identified related to controls (e.g. legislation) and feedback mechanisms (e.g. monitoring for behavioural adaptation). The study provides an example of how STAMP can be used to identify control structure gaps requiring attention to support the safe introduction of new technologies.

Ferritin heavy chain supports stability and function of the regulatory T cell lineage. EMBO J 2024; 43:1445-1483. [PMID: 38499786 PMCID: PMC11021483 DOI: 10.1038/s44318-024-00064-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2023] [Revised: 02/15/2024] [Accepted: 02/20/2024] [Indexed: 03/20/2024] Open
Abstract
Regulatory T (TREG) cells develop via a program orchestrated by the transcription factor forkhead box protein P3 (FOXP3). Maintenance of the TREG cell lineage relies on sustained FOXP3 transcription via a mechanism involving demethylation of cytosine-phosphate-guanine (CpG)-rich elements at conserved non-coding sequences (CNS) in the FOXP3 locus. This cytosine demethylation is catalyzed by the ten-eleven translocation (TET) family of dioxygenases, and it involves a redox reaction that uses iron (Fe) as an essential cofactor. Here, we establish that human and mouse TREG cells express Fe-regulatory genes, including that encoding ferritin heavy chain (FTH), at relatively high levels compared to conventional T helper cells. We show that FTH expression in TREG cells is essential for immune homeostasis. Mechanistically, FTH supports TET-catalyzed demethylation of CpG-rich sequences CNS1 and 2 in the FOXP3 locus, thereby promoting FOXP3 transcription and TREG cell stability. This process, which is essential for TREG lineage stability and function, limits the severity of autoimmune neuroinflammation and infectious diseases, and favors tumor progression. These findings suggest that the regulation of intracellular iron by FTH is a stable property of TREG cells that supports immune homeostasis and limits the pathological outcomes of immune-mediated inflammation.

The Effect of Wire Versus Magnetic Seed Localization on Lumpectomy Cavity Size. Pract Radiat Oncol 2023:S1879-8500(23)00347-8. [PMID: 38161002 DOI: 10.1016/j.prro.2023.12.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2023] [Revised: 11/29/2023] [Accepted: 12/01/2023] [Indexed: 01/03/2024]
Abstract
PURPOSE Our purpose was to assess whether an association exists between surgical localization technique and lumpectomy cavity size on radiation therapy planning computed tomography (CT) scan. METHODS AND MATERIALS A single-institution retrospective review was conducted of women undergoing breast conserving surgery with wire or magnetic seed guided lumpectomy followed by adjuvant radiation therapy from 2018 to 2021. Patients of a surgeon only performing 1 localization technique or undergoing bracketed localization were excluded. The primary outcome was lumpectomy cavity size on simulation CT. Confounding due to imbalance in patient and tumor factors was addressed with overlap weights derived from a propensity score analysis and used in a weighted multivariable analysis. Secondary outcomes included positive margins, total pathologic volume, boost delivery, and boost modality. RESULTS Of 617 women who received lumpectomy during the study period, 387 were included in final analysis. Tumors of patients undergoing seed localization were more likely unifocal, assessable by ultrasound, and smaller. Seed use rates ranged from 27.7% to 70.7% per surgeon. There was no difference in positive margins (6.4 vs 5.4%, P = .79) or second surgeries (9.4 vs 8.1%, P = .79) between groups. Close margin rates were similar for ductal carcinoma in situ (P = .35) and invasive carcinoma (P = .97). In unadjusted bivariable analyses, wire localization was associated with larger total pathology volume (P = .004), but localization technique showed no association with CT cavity volume (P = .15). After adjusting for potentially confounding variables, multivariable analysis failed to show an association between localization technique and either CT cavity (P = .35) or total path volume (P = .08). There was no difference in indicated-boost delivery (P = .15) or electron boost (P = .14) by localization technique. CONCLUSIONS There was no significant difference in CT cavity size by localization technique, suggesting choice between surgical techniques does not impede radiation therapy boost delivery.

Abstract
Artificial Intelligence (AI) is being increasingly implemented within road transport systems worldwide. Next generation of AI, Artificial General Intelligence (AGI) is imminent, and is anticipated to be more powerful than current AI. AGI systems will have a broad range of abilities and be able to perform multiple cognitive tasks akin to humans that will likely produce many expected benefits, but also potential risks. This study applied the EAST Broken Links approach to forecast the functioning of an AGI system tasked with managing a road transport system and identify potential risks. In total, 363 risks were identified that could have adverse impacts on the stated goals of safety, efficiency, environmental sustainability, and economic performance of the road system. Further, risks beyond the stated goals were identified; removal from human control, mismanaging public relations, and self-preservation. A diverse set of systemic controls will be required when designing, implementing, and operating future advanced technologies.Practitioner summary: This study demonstrated the utility of HFE methods for formally considering risks associated with the design, implementation, and operation of future technologies. This study has implications for AGI research, design, and development to ensure safe and ethical AGI implementation.

Abstract
BACKGROUND Healthcare providers often encounter clinical trial results in the form of visual data displays. Although there is a robust literature on patient responses to data displays in medical settings, less is known about how providers comprehend and apply this information. Our study provides a scoping review of the literature on providers' reactions to and perceptions of data displays. METHODS We searched article databases (PubMed, PsycINFO, Web of Science, Cumulative Index to Nursing and Allied Health Literature, the Cochrane Library) supplemented by handsearching. Eligible articles were published in English from 1990 to 2020. RESULTS We identified 15 articles meeting our criteria. Studies with physicians were more prevalent (13/15) than those with other healthcare providers (6/15). Commonly assessed outcomes included objective (10/15) and subjective comprehension (4/15), preference for certain data display formats (6/15), and hypothetical decision-making around prescribing (4/15). In studies that assessed comprehension of clinical trial concepts, scores were average or below what would be considered mastery of the information. Data display formats that were preferred did not always correlate with better comprehension of information; lesser preferred formats (e.g. icon array) often resulted in better comprehension. CONCLUSION Our findings suggest that healthcare providers may not accurately interpret complex types of data displays, and it is unknown if such limitations affect actual decision-making. Interventions are needed to enhance comprehension of complex data displays within the context of prescription drug professional promotion.

Abstract
Introduction Indoor tanning beds cause more than 450,000 new skin cancers each year, yet their use remains common, with a global indoor tanning prevalence of 10.4%. Social media provides an opportunity for cost-effective, targeted public health messaging. We sought to direct Instagram users at high risk of indoor tanning to accurate health information about the risks of indoor tanning and to reduce indoor tanning bed use. Methods We disseminated a public health campaign on Instagram on April 6-27, 2022 with 34 video and still-image advertisements. We had 2 target audiences at high risk of indoor tanning: women aged 18-30 years in Kentucky, Nebraska, Ohio, or Tennessee interested in indoor tanning and men aged 18-45 years in California interested in indoor tanning. To evaluate the impact of the campaign, we tracked online metrics, including website visits, and conducted an interrupted time-series analysis of foot traffic data in our target states for all tanning salons documented on SafeGraph from January 1, 2018 to 3 months after the campaign. Results Our indoor tanning health information advertisements appeared on Instagram feeds 9.1 million times, reaching 1.06 million individuals. We received 7,004 views of our indoor tanning health information landing page (Average Time on Page of 56 seconds). We did not identify a significant impact on foot traffic data on tanning salons. Conclusions We show the successful use of social media advertising to direct high-risk groups to online health information about indoor tanning. Future research quantifying tanning visits before and after indoor tanning interventions is needed to guide future public health efforts.

Protocolized screening and detection of occult alcohol use before and after liver transplant: Lessons learned from a quality improvement initiative. Clin Transplant 2023; 37:e15036. [PMID: 37218656 DOI: 10.1111/ctr.15036] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2022] [Revised: 05/09/2023] [Accepted: 05/13/2023] [Indexed: 05/24/2023]
Abstract
INTRODUCTION Detection of alcohol (ETOH) use with biomarkers provides an opportunity to intervene and treat patients with alcohol use disorder before and after liver transplant (LT). We describe our center's experience using urine ethyl glucuronide (EtG) and serum phosphatidylethanol (PEth) in alcohol screening protocols. METHODS Single-center, retrospective review of patients presenting for LT evaluation, patients waitlisted for LT for alcohol-associated liver disease (ALD), and patients who received a LT for ALD over a 12-month period, from October 1, 2019 through September 30, 2020. Patients were followed from waitlisting to LT, or for up to 12 months post-LT. We monitored protocol adherence to screening for ETOH use- defined as completion of all possible tests over the follow-up period- at the initial LT visit, while on the LT waitlist and after LT. RESULTS During the study period, 227 patients were evaluated for LT (median age 57 years, 58% male, 78% white, 54.2% ALD). Thirty-one patients with ALD were placed on the waitlist, and 38 patients underwent LT for ALD during this time period. Protocolized adherence to screening for alcohol use was higher for PEth for all LT evaluation patients (191 [84.1%] vs. 146 [67%] eligible patients, p < .001), in patients with ALD waitlisted for LT (22 [71%] vs. 14 (48%] eligible patients, p = .04) and after LT for ALD, 20 (33 [86.8%] vs. 20 [52.6%] eligible patients, p < .01). Few patients with a positive test in any group completed chemical dependency treatment. CONCLUSIONS When screening for ETOH use in pre- and post-LT patients, protocol adherence is higher using PEth compared to EtG. While protocolized biomarker screening can detect recurrent ETOH use in this population, engagement of patients into chemical dependency treatment remains challenging.

Examining factors for the adoption of silvopastoral agroforestry in the Colombian Amazon. Sci Rep 2023; 13:12252.

Abstract
Current land use systems in the Amazon largely consist of extensive conventional productivist livestock operations that drive deforestation. Silvopastoral systems (SPS) support a transition to low carbon production if they intensify in sympathy with the needs of biophysical and socio-economic contexts. SPS have been promoted for decades as an alternative livestock production system but widespread uptake has yet to be seen. We provide a schema of associating factors for adoption of SPS based on past literature in tropical agriculture and apply this to a bespoke survey of 172 farms in the Caquetá region of the Colombian Amazon. We find a number of factors which do not apply to this region and argue for a context specific approach. The impact of managing increased market access and opportunities for SPS producers are crucial to avoiding additional deforestation. Further understanding of the underlying antecedents of common factors, such as perceptions of silvopastoral systems, would reduce the risk of perverse policy outcomes.

Abstract
INTRODUCTION Life-threatening haemorrhage is the leading cause of potentially survivable injury in battlefield casualties. During Operation HERRICK (Afghanistan), mortality rates improved year on year due to a number of advances in trauma care, including haemostatic resuscitation. Blood transfusion practice has not previously been reported in detail during this period. METHODS A retrospective analysis of blood transfusion at the UK role 3 medical treatment facility (MTF) at Camp Bastion between March 2006 and September 2014 was performed. Data were extracted from two sources: the UK Joint Theatre Trauma Registry (JTTR) and the newly established Deployed Blood Transfusion Database (DBTD). RESULTS 3840 casualties were transfused 72 138 units of blood and blood products. 2709 adult casualties (71%) were fully linked with JTTR data and were transfused a total of 59 842 units. Casualties received between 1 unit and 264 units of blood product with a median of 13 units per patient. Casualties wounded by explosion required almost twice the volume of blood product transfusion as those wounded by small arms fire or in a motor vehicle collision (18 units, 9 units, and 10 units, respectively). More than half of blood products were transfused within the first 2 hours following arrival at the MTF. There was a trend towards balanced resuscitation with more equal ratios of blood and blood products being used over time. CONCLUSION This study has defined the epidemiology of blood transfusion practice during Operation HERRICK. The DBTD is the largest combined trauma database of its kind. It will ensure that lessons learnt during this period are defined and not forgotten; it should also allow further research questions to be answered in this important area of resuscitation practice.

Abstract
BACKGROUND Healthcare providers (HCPs) often encounter clinical trial results in the form of data displays in prescription drug promotions. Information conveyed in data displays vary in their presentation and complexity. This study describes characteristics of data displays in prescription drug advertising targeted to HCPs. METHODS This study characterized the content of 140 data displays in 98 unique print advertisements from 2009 to present and identified in AdPharm, an online database of pharmaceutical advertisements. Two reviewers independently coded the advertisements for characteristics (κ = 0.85) including complexity, format, and quality. RESULTS About one-third (32%) of the advertisements contained multiple data displays (range 2 to 6) and 44% showed clinical data from oncology trials; other disease domains were mental and behavioral health (14%), rheumatology and autoimmune disorders (8%), endocrinology (7%), cardiology (6%), infectious disease (6%), pulmonology and allergy (4%), and others (< 2% each). About one-half (51%) of displays were classified as "simple" which included "pseudographs" and basic tables or charts. "Complex" displays appeared as survival curves, line graphs, or bar graphs with complex features. Most complex displays included a comparator drug (90%), plain language restatement of the key finding (93%) and disclosure statements (91%) with additional study details, although their placement varied. Complex displays were of high quality, according to our selected indicators; our analysis found no data distortion or errors. CONCLUSION Data displays in prescription drug advertising are often highly complex. Future research assessing understanding of data displays and the potentially beneficial effect of disclosures and other features is warranted.

Abstract
INTRODUCTION Augmented-reality (AR) smart glasses provide an alternative to standard computer display monitors (CDM). AR smart glasses may provide an opportunity to improve visualisation during fluoroscopy and interventional radiology (IR) procedures when there can be difficulty in viewing intra-procedural images on a CDM. The aim of this study was to evaluate radiographer perception of image quality (IQ) when comparing CDM and AR smart glasses. METHODS 38 radiographers attending an international congress evaluated ten fluoroscopic-guided surgery and IR images on both a CDM (1920 × 1200 pixels) and a set of Epson Moverio BT-40 AR smart glasses (1920 × 1080 pixels). Participants provided oral responses to pre-defined IQ questions generated by study researchers. Summative IQ scores for each participant/image were compared between CDM and AR smart glasses. RESULTS Of the 38 participants, the mean age was 39 ± 1 years. 23 (60.5%) participants required corrective glasses. In terms of generalisability, participants were from 12 different countries, the majority (n = 9, 23.7%) from the United Kingdom. For eight out of ten images, the AR smart glasses demonstrated a statistically significant increase in perceived IQ (median [IQR] 2.0 [-1.0 to 7.0] points) when compared to the CDM. CONCLUSION AR smart glasses appear to show improvements in perceived IQ when compared to a CDM. AR smart glasses could provide an option for improving the experiences of radiographers involved in image-guided procedures and should be subject to further clinical evaluations. IMPLICATIONS FOR PRACTICE Opportunities exist to improve perceived IQ for radiographers when reviewing fluoroscopy and IR images. AR smart glasses should be further evaluated as a potential opportunity to improve practice when visual attention is split between positioning equipment and image review.

Abstract
Abstract
Purpose/Objectives To assess whether an association exists between surgical localization technique and size of lumpectomy cavity on radiation (RT) planning CT scan. Adjuvant RT with boost to lumpectomy cavity has been shown to improve local control compared to adjuvant whole breast radiation alone, but larger cavity sizes can lead to worse cosmetic outcomes following boost administration, which could lead providers to omit boost. Therefore, decreasing cavity size could increase guideline-concordant boost administration and minimize adverse cosmetic outcomes. Materials/Methods A retrospective review was conducted of all patients undergoing breast conserving surgery with either wire- or magnetic seed -guided lumpectomy followed by adjuvant RT at a single institution from 2018 to 2021. Data were collected from pre-surgical work-up, surgical pathology, and radiation planning. Women undergoing bracketed wire localization and patients treated by a surgeon who only performed wire localized procedures were excluded. The primary outcome was lumpectomy cavity size as measured on planning CT. We first conducted an overlapping weights propensity score analysis to account for imbalance between groups in age, BMI, breast size as measured on planning CT scan, pre-operative imaging tumor volume, neoadjuvant therapies, lumpectomy histology (DCIS alone vs DCIS + invasive vs invasive alone vs invasive with lobular features vs no residual), and multifocality. Multivariable analysis (MVA) of CT cavity volume included the above weighted variables as well as surgeon and radiation oncologist. Secondary analyses included MVA of total pathologic volume, bivariable analysis of boost delivery, bivariable analysis of electron vs photon boost, stratification by surgeon, and fixed effect model for year of surgery. Results Of 617 women who received lumpectomy during the study period, 387 were included in final analysis. Patients who underwent seed localization were less likely to have multifocal disease, less likely to have calcifications on mammogram, more likely to have ultrasound measurements for pre-op imaging, and had smaller tumor size on pre-op imaging. Four surgeons performed all cases, with rates of seed use per surgeon ranging from 27.7% to 70.7% but generally increasing throughout the study period. There was no difference between wire and seed localization in the need for additional margins based on intra-operative margin analysis (58.4 vs 62.7%, p = 0.5). There was no difference in positive margins (6.4 vs 5.4%, p = 0.81) or second surgeries (9.4 vs 8.1%, p = 0.79). Rates of close margins were the same for DCIS (23.4 vs 17.3%, p = 0.35) and invasive carcinoma (7.6 vs 6.8%, p = 0.97) between techniques. Initial uncorrected bivariable analysis shows wire localization has a non-significant trend toward increased CT cavity volume (4.56cc, p = 0.15) and a significant association with total pathology volume (21.7cc, p = 0.004). For the primary outcome, breast size, time from surgery to simulation, and surgeon were all significantly associated with CT cavity volume but there was no significant difference by localization technique (p=0.38). For pathology volume, there was a non-significant trend toward increased specimen volume with wire localization (p = 0.07), and significant associations with BMI, histology, and pre-op imaging volume. When stratified by surgeon, there was no surgeon for whom one localization technique led to significantly different CT or pathology volume over the other. There were no significant changes of the treatment effect over time (p = 0.79). There was no significant difference between wire and seed localization in indicated boost delivery (85% vs 79%, p = 0.14) or electron boost (42% vs 56%, p = 0.13). Conclusion There was no significant difference in CT cavity size between wire localization and magnetic seed localization, suggesting that the choice between these surgical techniques does not impede RT boost delivery.

BACKGROUND Same-day discharge after mastectomy without immediate reconstruction (MwoR) has been shown to be safe, with improved patient satisfaction when compared with patients discharged 1 or more days after surgery. Nevertheless, only 16% of patients undergoing MwoR in Michigan are discharged on the day of surgery, with significant variation between facilities (3-88%). Our objective was to explore determinants of same-day discharge and offer strategies for broader implementation of this practice. METHODS We conducted semi-structured interviews with surgeons performing MwoR across the state of Michigan. Recruitment utilized purposeful and snowball sampling methods. The Tailored Implementation in Chronic Disease (TICD) framework was used to inform the creation of the interview guide. Interviews were transcribed and then analyzed using directed content analysis guided by the TICD framework. Salient determinants were organized into patient, provider, and system-level factors. RESULTS Participants (n = 26) included general surgeons, breast surgeons, and surgical oncologists. Most surgeons (n = 18, 69%) reported that they discharged fewer than 60% of patients the same day after MwoR. The most common barriers included patient knowledge at the patient level; awareness of evidence, surgeon dogma, and peer influence at the provider level; and team processes and operating room logistics at the system level. CONCLUSION We identified surgeon-defined determinants of same-day discharge after MwoR. For the identified barriers, potential implementation strategies could include incorporation of preoperative drain teachings for patients, utilizing consensus statements and opinion leaders to disseminate evidence supporting same-day mastectomies, and conducting workshops with relevant stakeholders to establish consistent facility practice patterns among surgical teams.

A scoping review of empirical research on prescription drug promotion. Res Social Adm Pharm 2023; 19:859-872. [PMID: 36931982 DOI: 10.1016/j.sapharm.2023.02.012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2022] [Revised: 02/21/2023] [Accepted: 02/22/2023] [Indexed: 03/04/2023]
Abstract
BACKGROUND Pharmaceutical spending on prescription drug promotion is considerable, and exposure to advertising can influence demand and behavior. The U.S. Food and Drug Administration (FDA) provides industry guidance to help ensure that communications to consumers and health care providers about prescription drug promotion are truthful, balanced, and accurately communicated. As empirical research has accelerated on this topic in the past decade, an understanding of the current landscape of the science will help inform future research. OBJECTIVES Using systematic methods, this rigorous scoping review of the literature over the past decade (2012-2021) (1) examined the extent to which prescription drug promotion has been empirically investigated with consumers, patients, and health care providers; (2) examined the extent to which content and features of prescription drug promotion have been empirically investigated; and (3) identified themes across the literature to better understand the current landscape of prescription drug promotion. METHODS Databases searched include PubMed, Web of Science, CINAHL, APA PsycInfo, Business Source Corporate, Communication Source, Cochrane Library, and ClinicalTrials.gov for original research published in English from January 1, 2012, through November 10, 2021, using terms related to direct-to-consumer advertising, prescription drugs, and outcomes of interest (e.g., attitudes, perceptions, intentions, behaviors). RESULTS Of 804 screened references, 151 studies addressed the first research question, and 40 studies addressed the second. The most common theme across the body of evidence focused on testing of features and content in prescription drug promotional materials (84), followed by studies examining attitudes, perceptions, and behaviors toward prescription drug promotion more generally (43). Some (27) studies focused on targeted populations, such as patients, the elderly, non-English speaking people or individuals of a non-white race/ethnicity. Twenty-four studies assessed influence of exposure to prescription drug promotion on actual clinical outcomes, while 11 studies examined emerging technologies around prescription drug promotion. Seven studies evaluated the extent to which prescription drug promotion complied with existing guidelines and requirements. CONCLUSIONS Findings from this scoping review suggest there has been an increase in the number of empirical studies conducted on prescription drug promotion over the past decade. Potential areas that warrant further study include examination of emerging technologies, an expanded focus on targeted populations, and construct measurement.

Abstract
BACKGROUND Preoperative imaging in clinical stage II melanoma is not indicated per National Comprehensive Cancer Network (NCCN) guidelines but remains common in clinical practice. METHODS Patients presenting with cutaneous clinical stage II melanoma from 2007 to 2019 were retrospectively reviewed. A clinical decision analysis with cost data was designed to understand ideal practice patterns in managing stage II melanoma, with pre-versus selective post-operative imaging as the initial decision node. RESULTS There were 277 subjects included, and 143 underwent preoperative imaging (49.5%). This changed management (i.e. no surgery) in one patient (0.4%). Overall, 16 patients had additional findings on imaging (5.8%). Upfront surgery with selective postoperative imaging was a more cost-effective strategy than routine performance of preoperative imaging, with savings of $1677 per patient. CONCLUSION Preoperative imaging is a low yield, costly approach for patients with clinical stage II melanoma with minimal impact on the decision to proceed with surgical management.

An orange will do: Suspending learner disbelief in simulations. CURRENTS IN PHARMACY TEACHING & LEARNING 2022; 14:1337-1339.

Abstract
INTRODUCTION Increasingly, educators are implementing simulation to supplement teaching. Where simulation is not already integral, difficulties have arisen with the utilization of simulation due to limited resources, training requirements, and educator uncertainty. PERSPECTIVE A learner's ability to suspend disbelief in a simulation can impact the effectiveness of learning. In other words, they become so immersed in the simulation that they ignore obvious limitations and choose to believe the activity is realistic. When designing simulations, educators need to consider intended learning outcomes (ILOs), realism, and briefings/debriefings to help learners suspend disbelief. Realism encompasses physical realism (fidelity), conceptual realism, and emotional/experiential realism. The ILOs should drive the simulation design and type of realism required. These should be presented to learners in a briefing, explaining where and why they may need to suspend disbelief; this should be reiterated during a debriefing to centre a learner's focus on whether the ILOs were met. Without this, learners may not "buy into" the simulation and instead can get lost in detail not relevant to their learning. IMPLICATIONS The use of cutting-edge equipment does not, on its own, ensure that learners get the most realistic learning experience. The goal of simulations should be to utilize resources in the most advantageous manner for attainment of ILOs. In a time when institutions may be pressured for time, staff, and resources, educators should remember that it is possible to facilitate effective learning in low-resource ways.

Abstract
Assisted dying refers to the steps of the administration of a voluntary assisted dying substance and the administration of the substance. In Australia, assisted dying is now legal in all states. However, there is limited knowledge of what underpins the community's attitudes toward assisted dying. It is important for health professionals to understand what underpins attitudes toward assisted dying when navigating the option with patients and family members. We used a survey based on the Tripartite Model of Attitudes to examine the degree to which beliefs, emotions, and experiences, as well as knowledge, underpinned attitudes towards assisted dying. With a sample of 108, we found emotions and beliefs to significantly explain attitudes towards assisted dying. Knowledge of assisted dying practices was low amongst the sample. Our findings suggest that education of assisted dying is required, and that attitudes towards assisted dying in the Australian community are underpinned by beliefs and emotions.

Abstract
There has been a renewed interest in the role of dietary therapies to manage irritable bowel syndrome (IBS), with diet high on the agenda for patients. Currently, interest has focussed on the use of traditional dietary advice (TDA), a gluten-free diet (GFD) and the low FODMAP diet (LFD). A consensus meeting was held to assess the role of these dietary therapies in IBS, in Sheffield, United Kingdom.Evidence for TDA is from case control studies and clinical experience. Randomised controlled trials (RCT) have demonstrated the benefit of soluble fibre in IBS. No studies have assessed TDA in comparison to a habitual or sham diet. There have been a number of RCTs demonstrating the efficacy of a GFD at short-term follow-up, with a lack of long-term outcomes. Whilst gluten may lead to symptom generation in IBS, other components of wheat may also play an important role, with recent interest in the role of fructans, wheat germ agglutinins, as well as alpha amylase trypsin inhibitors. There is good evidence for the use of a LFD at short-term follow-up, with emerging evidence demonstrating its efficacy at long-term follow-up. There is overlap between the LFD and GFD with IBS patients self-initiating gluten or wheat reduction as part of their LFD. Currently, there is a lack of evidence to suggest superiority of one diet over another, although TDA is more acceptable to patients.In view of this evidence, our consensus group recommends that dietary therapies for IBS should be offered by dietitians who first assess dietary triggers and then tailor the intervention according to patient choice. Given the lack of dietetic services, novel approaches such as employing group clinics and online webinars may maximise capacity and accessibility for patients. Further research is also required to assess the comparative efficacy of dietary therapies to other management strategies available to manage IBS.

Abstract
BackgroundJoint damage in the knee can be severe in both rheumatoid arthritis (RA) and osteoarthritis (OA) such that total knee replacement (TKR) is often the only management option. Pathological assessment of the extent or type of synovial tissue inflammation from joint explants or biopsies can be useful. However, an ongoing challenge in using semi-quantitative assessments of synovitis is the disagreement between human pathologist scores of the same sample. We previously developed and validated a computer vision algorithm to automatically count each cell nucleus in an H&E-stained synovial whole slide image and yield a value of cell density, defined as mean nuclei count per mm2 of tissue1.ObjectivesWe sought to develop methods to distinguish OA from RA based on machine learning analysis of histologic features on H&E-stained synovial tissue samples.MethodsWe measured 14 pathologist-scored histology features (137 RA and 152 OA patients) and computer vision quantified cell density (60 RA and 147 OA patients) in H&E stained synovial tissue samples from total knee replacement arthroplasty explants. A random forest model was trained using disease state (OA vs RA) as classifier and histology features and/or cell density as inputs, and feature importance scores for the model were calculated.ResultsSynovium from patients with RA exhibited increased lymphocytic inflammation, lining hyperplasia, neutrophils, detritus, plasma cells, Russell bodies, binucleate plasma cells, sub-lining giant cells, synovial lining giant cells, and fibrin (all p<0.001), while synovium from patients with OA had increased mast cells and fibrosis (both p<0.001). Fourteen pathologist-scored features allowed for discrimination between RA and OA samples, producing a macro-averaged area under the receiver operating curve (AUC) of 0.85. This discriminatory ability was comparable to that of the computer vision score of cell density alone (AUC = 0.88). Combining the pathologist scores with the cell density metric improved the discriminatory power of the model (AUC = 0.91). The three most important features in this combined model were mast cells followed by cell density and fibrosis (Figure 1). AUC values for each individual feature are provided in Table 1. The optimal cell density threshold to distinguish RA from OA synovium was 3,400 cells per mm2, which yielded a sensitivity of 0.82 and specificity of 0.82.Table 1.Area under receiver operating characteristic curves (AUC) of the synovial features in distinguishing RA and OA patientsFeatureAUCAutomated Cell Density0.88Fibrosis0.84Mast cells0.80Lining hyperplasia0.78Lymphocytic inflammation0.69Fibrin0.68Plasma cells0.66Detritus0.64Binucleate plasma cells0.60Neutrophils0.60Synovial giant cells0.58Sub-lining giant cells0.57Russell bodies0.56Germinal centers0.51Mucoid change0.50Figure 1.Importance of synovial features in distinguishing RA and OA synoviumFeature importance scores for supervised machine learning model including all 14 pathology scores and the computer vision-generated cell density.ConclusionH&E-stained images of RA and OA TKR explant synovium are distinct. We identified cell density, mast cells and fibrosis as the three most important features for making this distinction, with RA being characterized by increased cell density, low mast cells, and low fibrosis. Cell density greater than 3400 per mm2 of tissue yields a sensitivity of 0.82 and a specificity of 0.82 for distinguishing RA from OA. In the future, this can have clinical and research applications as this technique removes the requirement for subjective selection of a certain field of interest, is reproducible, and is scalable as it does not require technical expertise of a pathologist.References[1]Guan S, Mehta B…Orange DE.

Abstract
Purpose Identifying drivers of behavior is essential to develop effective messaging around COVID-19 prevention and mitigation. Our study assessed for behavioral antecedents of social distancing, wearing face coverings, and sheltering in place during the onset of the COVID-19 pandemic. Although ours is an early assessment, understanding motivation for behavior will remain critical as U.S. vaccination uptake has stalled and variants continue to pose a health threat. Design Cross-sectional survey; Setting: Online assessments in April 10–13 and 17–20, 2020; Subjects: 2,279 U.S. adults identified through a national, probability-based web panel (34% response rate). Measures: self-reported behavior, perceived effectiveness and risk, worry, social norms, and knowledge. Analysis Multivariable regression analyses Results Most Americans reported social distancing (91%) and sheltering in place (86%). Just over half reported wearing face coverings (51%), whereas more (77%) said they intended to do so. Perceived effectiveness of the behavior was consistently associated with each outcome (OR = 2.34, 1.40, 2.11, respectively; all P < .01). Perceptions about the extent to which others should comply with behavior (social norms) were strongly associated with intentions to wear a face covering only (OR = 6.30, 95% CI 4.34-9.15; P < .001) and worry about getting COVID-19 was associated with sheltering in place and social distancing (OR = 2.63, 95% CI 1.15–5.00; 4.91, 95% CI 1.66, 14.50, respectively; all P < .05). Conclusion Behavioral constructs were strongly associated with COVID-19 preventive and mitigation behaviors and have implications for communication.

Abstract
Abstract
Introduction
Coronavirus-2 is the virus responsible for the COVID-19 pandemic. People with certain risk factors, such as having chronic obstructive pulmonary disease (COPD) may be more likely to develop complications. Research has identified that ~7% of patients with COVID-19 have a bacterial infection, however antibiotic prescribing rates have been found to vary from 38% to 72% (1,2). Primary care is estimated to make up 75% of antibiotic prescribing and was therefore a key target to evaluate whether antimicrobial stewardship principles were being followed during the COVID-19 pandemic.
Aim
To audit the adherence of antibiotic prescribing in people with COPD during the COVID-19 pandemic across a primary care network (PCN) in England against national and local guidelines.
Methods
The management of patients with COPD should follow NICE Guideline (NG) 114, NG168 and the local formulary. Three audit standards were created: 1) 100% of COPD patients should not be started on prophylactic antibiotics to reduce risk from COVID-19; 2) 100% of COPD patients should not be prescribed antibiotics for COVID-19 symptoms; 3) 90% of antibiotic prescription regimens should adhere to local and national guidelines. Prescribing data was collected from 12 practices linked to the PCN. Data of patients who had COPD, were prescribed an antibiotic, and had an indication for the antibiotic between 01/03/20 and the 30/06/20 were extracted and transferred into an anonymised spreadsheet. A total of 1088 data points were extracted. Random stratified sampling provided 300 data points for analysis, ensuring each GP surgery was represented proportionally; the required sample size to determine significance was 291. For each practice, the total number of antibiotics prescribed to COPD patients between March-June 2019 and March-June 2020 was extracted. Descriptive statistics were used to determine antibiotic prescribing adherence and overall rates of prescribing. Inferential statistics were used to compare rates of prescribing pre-vs-during the pandemic.
Results
Antibiotics were not prescribed for any patient for prophylaxis against COVID-19 (100% adherence to criteria 1). Two patients were prescribed antibiotics for ‘suspected disease caused by COVID-19’ (99.4% adherence to criteria 2). In only 28.7% of cases, the antibiotic was prescribed in line with the national and local guidelines (criteria 3). In most cases, treatment duration was the main reason for poor adherence, with longer courses of antibiotics being prescribed (7 rather than 5 days). Prescribing rates did not change significantly in 2020 compared to 2019 (1134 antibiotic prescriptions vs 1029 antibiotic prescriptions; p>0.05).
Conclusion
The audit was successful in determining that the COVID-19 pandemic did not significantly affect antibiotic prescribing rates across the PCN for people with COPD. Adherence to NICE and local guidelines was low, specifically concerning the duration of antibiotic treatment. This highlights an area for improvement; to ensure healthcare professionals across the PCN prescribe in-line with antimicrobial stewardship principles. Extracted data was limited to antibiotic prescribing and could have been expanded to include steroids to provide a fuller audit of prescribing in COPD exacerbations. A re-audit may be beneficial since the publication of NG191.

Abstract
Abstract
Introduction
Within the context of education, motivation relates to the desire students possess to engage in their learning environment. This quality is vital in determining the effort an individual expresses towards their learning and the desire they have to achieve higher academic performances (1). Educational technologies, particularly digital technologies, have long been used in post-secondary education to increase collaboration, critical thinking and motivation among students (2). The advancements in technology have led to the creation of novel augmented reality (AR) educational tools, however they have not been widely implemented or researched with the education of pharmacy students in the United Kingdom.
Aim
To identify changes of pharmacy students’ self-reported intrinsic motivation towards learning after using the ‘Pharma Compounds AR’ (PCAR) educational tool.
Methods
The PCAR tool was an image-based educational AR mobile application – it displayed 3-D models and animations of complex molecules when unique target images were scanned with the mobile’s camera. 118 stage two undergraduate Pharmacy students from a University in England were approached through cohort emails that contained a link to an online consent form and pre-intervention questionnaire. Participants were required to complete the pre-questionnaire before they received the PCAR tool for at least two months. Students were informed that they could use the tool to accommodate their learning in any way they felt appropriate. Once the intervention period ended, participants completed an online post-questionnaire. Changes in self-reported intrinsic motivation were determined with the use of adapted Intrinsic Motivation Inventory (IMI) Likert scale questions. The pre-questionnaire focused on motivation towards learning using conventional methods and their perceived usefulness, whereas the post-questionnaire focused on motivation towards learning with the PCAR tool and its perceived usefulness. Descriptive and inferential statistical analyses were conducted on the IMI adapted Likert scales.
Results
A total of 68 (57.6% rr) undergraduate Pharmacy students completed the pre-questionnaire. The majority were aged 18-21(82.4%), female (70.6%) and domestic (94.1%). The post-questionnaire was completed by 30 students (44.1% rr), mainly aged 18-21 (83.3%), female (70%), and domestic (86.7%). Participants ranked their agreement to each Likert statement from 1 (not true at all) to 7 (very true). Mean agreement motivation scores were increased after the use of the PCAR tool (pre-3.88 vs post-5.15), as were the mean agreement scores of the learning tools’ perceived usefulness (pre-4.69 vs post-5.29). Dependant T-tests performed on responses of students who completed both questionnaires revealed a significant increase in students’ mean pre- and post-intervention motivation towards learning scores (p=0.000). No significance was calculated between the mean pre-and post-agreement usefulness scores (p>0.05).
Conclusion
Incorporating the PCAR tool into the education of stage two Pharmacy students significantly increased their reported motivation towards learning when compared to conventional methods, it was also reported as being a more useful learning tool. The drop in post-questionnaire responses has to be acknowledge as a limitation as well as not explicitly knowing how students used the PCAR tool in their studies. Nevertheless, the incorporation of AR into schools of Pharmacy could provide students and tutors more engaging teaching and learning experiences.

Abstract
Abstract
Introduction
As a result of changes in the demands and pressures on the NHS, the role of the pharmacist has advanced from purely dispensing and compounding medicines to a more clinical and patient-centred approach to care (1). Since 2015, NHS England set a target of recruiting practice-based pharmacists into 20% of practices by 2020-2021 as a way of reducing these pressures (2). Conducting evaluations of clinical pharmacists in individual practices is essential for role integration and evolution.
Aim
To explore patient perceptions of clinical pharmacists across three general practices.
Methods
A paper-based questionnaire consisting of open and closed questions was used to gather patient perceptions on the role of a clinical pharmacist and their consultation experiences. Participants included patients over the age of 18 who had attended a face-to-face appointment with a clinical pharmacist from one of three general practice surgeries in England between November and December 2019. The clinical pharmacists were used as a gateway to recruit participants; post-consultation, the pharmacist asked patients if they would complete a questionnaire. Patients were provided with an information sheet and consent form prior to completion of the questionnaire. The questionnaire was anonymous. Data were analysed using descriptive statistics and content analysis.
Results
A total of 39 participants completed the questionnaire. Most participants were elderly (28%) and female (64%). The primary reason for the consultations was due to an acute illness (79%), and the most common outcome was the supply of a prescription (83%). Patients were predominantly unfamiliar with the role of a clinical pharmacist (56%) and 31% of patients reportedly thought their appointment had been with a doctor. All patients were positive about their experience and reported they would “be more than happy to see a pharmacist in the future” and that the role was “a very necessary addition to the practice”. All patients reported that their consultation was the same (51%) or better than they have had with a doctor (49%). Patients commented on the pharmacists’ consultation skills, making statements such as [they] “listened to me”, “asked me questions”, “were really good at explaining” and “spoke in a way I understood”. Clinical pharmacists were reported as being “very professional” and knowledgeable as “[they] knew more about my medication [than the doctor] and prescribed me something to help”. Patients reported that they would recommend the clinical pharmacist to their family and friends when seeking an appointment.
Conclusion
This research highlights patient acceptance towards consultations with a clinical pharmacist and reinforces the competence of pharmacists to undertake this role. A key finding related to the effective consultation skills of the pharmacists and involving the patients in their care. The number of patients who participated limits the generalisability of the findings, and the patient responses may have been a reaction to the individual clinical pharmacists rather than their thoughts on the role overall. Increased publicity and patient education of the role of a clinical pharmacist may promote a greater integration into the multidisciplinary team.

Abstract
Abstract
Introduction
In frailty, Comprehensive geriatric assessment (CGA) has benefit in improving patient outcomes, including hospital readmissions and institutionalisation. We looked to evaluate the effectiveness of our newly initiated multi-disciplinary, acute frailty team (AFT) in improving acute care. This team works on the Acute Medical Unit (AMU), delivering early CGA alongside the existing acute medical care.
Methods
The AFT initially targeted identification of frailty using the Rockwood clinical frailty score (CFS) through local quality improvement work. A standard operating procedure, encompassing CGA for all patients with frailty (define as a CFS 5 to 8 or, 4 with a frailty syndrome) was introduced. This assessment was additional to usual acute medical care. The impact was measured by retrospective case note review of 100 AMU admissions with frailty prior to the team being in post (Jan-March 2020) with a subsequent 100 patients seen by the AFT (March–April 2021). The 2 groups were matched for age, gender, frailty scores and pre-admission residence. These 2 cohorts were compared against key performance indices.
Results
The mean age of patients in the Pre and post AFT cohorts were 85 years and 84 years respectively with an average CFS of 6. The identification and documentation of frailty improved in the AFT intervention cohort from 31% to 100% and screening for delirium with 4AT improved from 27% to 91%. The number of patients in the AFT cohort discharged directly from AMU increased from 5% to 14% with the average length of in-patient stay reducing from 10.2 days to 7.8 days. Thirty day remission fell from 23% to 16% in the AFT cohort, and the number of patients discharge to new 24 hour care declined from 21% to 9%.
Conclusion
Our AFT alongside existing acute medical care improved outcomes including, frailty identification, delirium screening, length of stay, re-admissions and institutionalisation.

Abstract
OBJECTIVE Adverse childhood experiences (ACEs) and lifetime traumatic events are closely linked to development of comorbid psychiatric symptoms and substance use. Although research shows the risk for psychiatric and substance use comorbidity conferred by early adversity, most studies have not modeled multivariate symptom patterns that include posttraumatic stress disorder (PTSD) symptom criteria (i.e., re-experiencing, effortful avoidance, numbing, and hyperarousal). The aim of the present study was to model multivariate patterns of substance use and psychiatric symptoms, including PTSD criteria, and examine associations between these patterns and early adversity. METHOD Latent profile analysis (LPA) was used in a large, nonclinical sample of community adults (N = 1,431). Relations between profile membership, cumulative ACEs, and demographic covariates were then evaluated. RESULTS Results indicated four distinct profiles of psychiatric symptom comorbidity (PSC): (a) PTSD dominant with elevated illicit drug and cannabis use; (b) anxiety and depression dominant with elevated use across substances; (c) avoidance dominant with low severity of all other psychiatric symptoms and substance use; and (d) psychiatrically healthy. Analyses identified significant associations between profile membership and cumulative ACEs and other traumatic events. Cumulative ACEs and traumatic events were highest among the PTSD dominant profile. CONCLUSIONS A greater understanding of heterogeneous patterns of PSC may allow for future development of treatment care paths that correspond to standard criteria of symptom presentation and severity.

Temporal trends of perfluoroalkyl substances in an Australian wastewater treatment plant: A ten-year retrospective investigation. THE SCIENCE OF THE TOTAL ENVIRONMENT 2022; 804:150211. [PMID: 34798742 DOI: 10.1016/j.scitotenv.2021.150211] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/09/2021] [Revised: 09/01/2021] [Accepted: 09/03/2021] [Indexed: 06/13/2023]
Abstract
Per- and poly-fluoroalkyl substances (PFAS) are a problematic group of chemicals used in various industrial and household products. They have been extensively detected in wastewater as a result of day-to-day product usage. Due to concerns about their safety, voluntary and regulatory action to limit the manufacture and use of some individual PFAS has occurred since the year 2000. The impact that this intervention has had on the use and potential exposure of Australians has not been measured. Wastewater serves as a powerful tool to assess the chemical use or consumption patterns of a population over time. We accessed a ten-year wastewater archiving program to conduct a temporal analysis of PFAS trends in an urban Australian population between the years 2010 and 2020. Results showed a decline in the concentrations for most PFAS, and a change in the PFAS profile from perfluorosulfonic acids and long-chain perfluorocarboxylic acids, to the short-chain perfluorocarboxylic acids and PFOS-replacement degradation products such as 5:3 FTCA. Intermittent pulses of PFAS that were significantly higher than 'background' levels (i.e., representing the PFAS input from primarily households) were observed, suggesting continuing industrial PFAS input within the wastewater catchment. This study highlights the long-term consequences of the diffuse use of persistent chemicals in products, and their ability to continue to enter the wastewater stream for decades.

Abstract
New therapies that address the underlying pathophysiology of Alzheimer’s Disease (AD), coupled with the growth of the AD population, will transform the AD care pathway and present significant challenges to health systems. We explored real-world challenges health systems may face in delivering potential new AD therapies with diverse stakeholders. Key challenges in care included integrating primary care providers into assessment and management, availability of memory care specialists, understanding payment and coverage issues and training mid-level providers to help coordinate care and serve as a shared resource across the system. This input informed a novel Site Readiness Framework for AD, comprising self-assessment exercises to identify health system capabilities and gaps and a framework of core strategies and responsive tools to help prepare to integrate new AD therapies. These resources may help health systems improve readiness to modify care pathways to integrate new therapies for AD.

Abstract
Background Bacterial coinfection in COVID-19 is infrequent, yet empiric antibiotic use is common. The objectives of this study were to investigate the effect of empiric antibiotics on time to resolution of COVID-19 pneumonia, elucidate the impact of COVID-19 on procalcitonin levels, and determine the incidence of respiratory bacterial coinfection. Methods This was a retrospective study of adult patients hospitalized with COVID-19 between June 1, 2020 and September 30, 2020. Patients were included if they had at least one procalcitonin level. They were excluded if admitted to an intensive care unit within 24 hours of presentation or received antibiotics for an indication besides pneumonia. Patients were stratified into 4 groups based on procalcitonin level and receipt of antibiotics. The primary outcome was time to clinical resolution of pneumonia. A key secondary outcome was incidence of confirmed respiratory bacterial coinfection. Results A total of 199 patients were included. Patients with a procalcitonin greater than 0.25 ng/mL who received antibiotics had a longer median time to clinical resolution of pneumonia, 8 days (95% CI, 4 to 11 days) vs. 3 or 4 days in other groups (P< 0.001). Additionally, this same group required greater baseline oxygen supplementation, had more comorbidities, and increased mortality compared to all other groups. Median time to clinical resolution of pneumonia was also longer in patients who received antibiotics compared to those who did not (5 vs. 4 days, P=0.017) and in those with a procalcitonin greater than 0.25 ng/mL compared to those with PCT less than or equal to 0.25 ng/mL (7 vs. 4 days, P< 0.001). Renal dysfunction was more prevalent in patients with an elevated procalcitonin (45% vs. 17.5%). The overall incidence of confirmed respiratory bacterial coinfection was 1.5%. Conclusion Irrespective of procalcitonin level, empiric antibiotics were not associated with a shorter time to resolution of COVID-19 pneumonia in non-critically ill patients. Elevated procalcitonin is likely a reflection of the severity of COVID-19 disease and baseline renal function rather than bacterial infection. Additionally, the overall incidence of confirmed bacterial coinfection in non-critically ill patients hospitalized with COVID-19 was low. Disclosures Kiya D.

Abstract
The present research was motivated by a prior study, where several wallets, each containing a photo of either a baby, a puppy, a family, or an elderly couple, were scattered across a city in the United Kingdom. Most of the wallets containing a photo of a baby were returned compared with less than one-third of the wallets containing a photo of an elderly couple. To investigate further, in a series of three studies we examined, using a pseudo online version of the dictator game, possible subtle cues supporting prosocial behaviour by manipulating the type of avatar used by the recipient of the donation made by the “dictator.” Overall, it emerged that participants showed significantly higher levels of generosity towards babies and older people, supporting the notion that perceptions of vulnerability and need drive prosocial behaviour.

Abstract
Abstract
Aim
In addition to a reduction in elective surgery, the COVID-19 pandemic has been associated with concerning rates of post-operative mortality in COVID-19 patients highlighting the threat of nosocomial transmission. Relocation of elective patients into a protected cold wing of a tertiary centre, vigilant testing and staff test, and trace were implemented to address these issues.
Method
Retrospective analysis of 5069 consecutive patients who underwent procedures in theatre from 11/03/20 – 08/09/20 was performed. Comparison of numbers of procedures was compared with the same study dates in 2019. Detailed analysis of nosocomial transmission of COVID-19 and mortality was performed using patient notes and death certificates.
Results
5854 procedures were performed in 2020 compared with 13219 in 2019, representing a reduction of 55.7%. The overall mortality in 2020 was 2.7% (135/5069). COVID-19 negative mortality was 2.36% (119/5033). 74 patients tested positive for COVID-19 at any time (1.3%); mortality amongst patients who tested positive seven days pre- to 30 days post-procedure was 5.4% (4/74). Nosocomial transmission rate was 0.27% in elective admissions (10/3773) and 0.97% in acute admissions (20/2052).
Conclusions
The first wave of the pandemic has predictably caused a significant reduction in elective activity. Our hospital infection prevention measures have kept nosocomial transmission rates low, particularly for elective admissions. We have observed lower rates of post-operative mortality in COVID-19 patients than published in other centres. Continuation of surgical services is important for patient outcomes, and essential for training the surgeons of tomorrow.
