Background: Surgical procedures present intricate challenges within healthcare delivery, often associated with higher risks of adverse events compared with non-surgical contexts. Patient and family engagement (PFE) throughout the perioperative journey is a possibility to enhance care quality, safety and patient-centredness. However, literature addressing PFE across the entirety of the perioperative journey remains sparse. Objective: The current scoping review aims to comprehensively map the existing interventions with PFE approach focused on improving patient safety across various types of surgical procedures throughout the perioperative journey. In addition, the review aims to understand the level and type of PFE approach adopted in this context. Eligibility criteria: Articles published in indexed peer-reviewed journals from 2003 to 2023, written in English, Portuguese or Spanish, that report on interventions with PFE approach targeting adult surgical patients, their families, caregivers, patient advocates and patient champions. The review includes articles reporting on both inpatient and ambulatory surgical patients. Methods: Following Joanna Briggs Institute guidelines and the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews framework, this review systematically searched PubMed, Web of Science, SCOPUS, CINAHL, and PsycINFO for relevant articles. Eligible interventions were categorised using PFE framework regarding the level of engagement and mapped according to the WHO Global Patient Safety Action Plan 2021-2030. Results: Out of 765 records initially identified, 32 met the eligibility criteria for data extraction and analysis, of which 40% originated from the USA, followed by the UK (18%) and Canada (12%). 47% of the interventions targeted 'multiple/all types' of procedures, 19% focused on cardiothoracic surgeries and 9% on gynaecological procedures or organ transplant. The majority of the interventions (88%) focused on PFE at the direct care level, predominantly adopting a consultation-based approach. Furthermore, 81% of eligible interventions emphasised patient information and education, 16% addressed codevelopment of policy and 3% of interventions focused on patient advocacy. Conclusion: The findings show a predominant focus on PFE interventions targeting patient safety at the direct care level, particularly in the provision of patient information and education. However, interventions at organisational and policy-making levels are notably scarce. Further investment is required to promote interventions engaging patients and families at broader organisational and policy-making levels.

BACKGROUND: Clinical errors in intensive care units (ICUs) are consistently attributed to communication errors. Despite its importance for patient safety and quality in critical care settings, few studies consider interprofessional communication as more than the basic exchange of information. METHODS: We conducted a scoping review of interprofessional communication in ICUs to (1) characterize how communication is defined and measured and (2) identify contributions the field of health communication can make to team communication in ICUs. Through a series of queries in PubMed and Communication and Mass Media Complete databases, we identified and compared persistent gaps in how communication is framed and theorized in 28 publications from health services and 6 from social science outlets. We identified research priorities and suggested strategies for discussing communication more holistically in future health services research. RESULTS: 34 articles published from 1999 to 2021 were included. Six explicitly defined communication. Six were published in social science journals, but none were authored by a communication studies scholar. Half of the articles addressed communication as a transaction focused on information transfer, and the other half addressed communication as a process. CONCLUSIONS: Methodological implications are identified with the intent to encourage future interdisciplinary collaboration for studying communication in ICUs. We discuss the importance of (1) using language to describe communication that facilitates interdisciplinary engagement, (2) prioritizing communication as a process and using qualitative methods to provide insight, and (3) engaging health communication theories and experts to assist in developing more fruitful research questions and designs.

Importance Large language models (LLMs) may facilitate the labor-intensive process of systematic reviews. However, the exact methods and reliability remain uncertain. Objective To explore the feasibility and reliability of using LLMs to assess risk of bias (ROB) in randomized clinical trials (RCTs). Design, Setting, and Participants A survey study was conducted between August 10, 2023, and October 30, 2023. Thirty RCTs were selected from published systematic reviews. Main Outcomes and Measures A structured prompt was developed to guide ChatGPT (LLM 1) and Claude (LLM 2) in assessing the ROB in these RCTs using a modified version of the Cochrane ROB tool developed by the CLARITY group at McMaster University. Each RCT was assessed twice by both models, and the results were documented. The results were compared with an assessment by 3 experts, which was considered a criterion standard. Correct assessment rates, sensitivity, specificity, and F1 scores were calculated to reflect accuracy, both overall and for each domain of the Cochrane ROB tool; consistent assessment rates and Cohen kappa were calculated to gauge consistency; and assessment time was calculated to measure efficiency. Performance between the 2 models was compared using risk differences. Results Both models demonstrated high correct assessment rates. LLM 1 reached a mean correct assessment rate of 84.5% (95% CI, 81.5%-87.3%), and LLM 2 reached a significantly higher rate of 89.5% (95% CI, 87.0%-91.8%). The risk difference between the 2 models was 0.05 (95% CI, 0.01-0.09). In most domains, domain-specific correct rates were around 80% to 90%; however, sensitivity below 0.80 was observed in domains 1 (random sequence generation), 2 (allocation concealment), and 6 (other concerns). Domains 4 (missing outcome data), 5 (selective outcome reporting), and 6 had F1 scores below 0.50. The consistent rates between the 2 assessments were 84.0% for LLM 1 and 87.3% for LLM 2. LLM 1's kappa exceeded 0.80 in 7 and LLM 2's in 8 domains. The mean (SD) time needed for assessment was 77 (16) seconds for LLM 1 and 53 (12) seconds for LLM 2. Conclusions In this survey study of applying LLMs for ROB assessment, LLM 1 and LLM 2 demonstrated substantial accuracy and consistency in evaluating RCTs, suggesting their potential as supportive tools in systematic review processes.

Objective: Non-invasive brain stimulation (NIBS) is beneficial to adult patients with depression, but its safety and efficacy in combination with antidepressants in children and adolescents with depression are not clear. We conducted a preliminary meta-analysis to objectively evaluate its clinical effect and provide information for future research and clinical practice. Methods: PubMed, Cochrane Library, Embase, and Web of Science were searched systematically to find clinical trials published in English before April 11, 2023. Stata software was used for meta-analysis, and random or fixed effect models were used to combine effect sizes. Results: Nine studies were eligible and included (n = 393). No articles about children were included in the analysis. The results showed that the remission rate was 40% (95% confidence interval [CI]: 13% to 71%). The scores of Children's Depression Rating Scale (CRDS) and Hamilton's depression scale (HAMD) significantly decreased compared to baseline value (MD = -27.04, 95% CI: -30.95, -23.12 and MD = -12.78, 95% CI: -19.55 to -6.01). In addition, the incidence of all adverse events was 13% (95% CI: 5%, 23%), and all were minor pain-related events. Conclusion: The combination of NIBS and antidepressants has been shown to notably alleviate depressive symptoms in adolescents, offering a considerable level of safety. This therapeutic synergy is particularly effective in patients with major depressive disorder, where repetitive transcranial magnetic stimulation augmented with antidepressants can enhance the amelioration of depressive symptoms.

Authors' objectives: The chimeric antigen receptor (CAR) T-cell therapies tisagenlecleucel (tisa-cel) and axicabtagene ciloleucel (axi-cel) are provisionally listed in Appendix 1 of the Health Insurance Benefits Ordinance in Switzerland until 31 December 2024 for the third-line treatment of B-cell acute lymphoblastic leukaemia (B-ALL), diffuse large B-cell lymphoma (DLBCL) and primary mediastinal B-cell lymphoma (PMBCL). This health technology assessment (HTA) evaluates the available evidence regarding the efficacy, effectiveness, safety, costs, cost-effectiveness and budget impact of tisa-cel and axi-cel compared to standard care in these populations. Ethical, legal, social and organisational issues associated with these therapies are also explored.

Aim: Sacral neuromodulation (SNM) is a minimally invasive treatment option for functional constipation. Evidence regarding its effectiveness is contradictory, driven by heterogeneous study populations and designs. The aim of this study was to assess the effectiveness, safety and cost-effectiveness of SNM in children and adults with refractory idiopathic slow-transit constipation (STC). Method: OVID Medline, OVID Embase, Cochrane Library, the KSR Evidence Database, the NHS Economic Evaluation Database and the International HTA Database were searched up to 25 May 2023. For effectiveness outcomes, randomized controlled trials (RCTs) were selected. For safety outcomes, all study designs were selected. For cost-effectiveness outcomes, trial- and model-based economic evaluations were selected for review. Study selection, risk of bias and quality assessment, and data extraction were independently performed by two reviewers. For the intervention 'sacral neuromodulation' effectiveness outcomes included defaecation frequency and constipation severity. Safety and cost-effectiveness outcomes were, respectively, adverse events and incremental cost-effectiveness ratios. Results: Of 1390 records reviewed, 67 studies were selected for full-text screening. For effectiveness, one cross-over and one parallel-group RCT was included, showing contradictory results. Eleven studies on safety were included (four RCTs, three prospective cohort studies and four retrospective cohort studies). Overall infection rates varied between 0% and 22%, whereas reoperation rates varied between 0% and 29%. One trial-based economic evaluation was included, which concluded that SNM was not cost-effective compared with personalized conservative treatment at a time horizon of 6 months. The review findings are limited by the small number of available studies and the heterogeneity in terms of study populations, definitions of refractory idiopathic STC and study designs. Conclusion: Evidence for the (cost-)effectiveness of SNM in children and adults with refractory idiopathic STC is inconclusive. Reoperation rates of up to 29% were reported.

Purpose: To critically assess the role and added value of knowledge graphs in pharmacovigilance, focusing on their ability to predict adverse drug reactions. Methods: A systematic scoping review was conducted in which detailed information, including objectives, technology, data sources, methodology, and performance metrics, were extracted from a set of peer-reviewed publications reporting the use of knowledge graphs to support pharmacovigilance signal detection. Findings: The review, which included 47 peer-reviewed articles, found knowledge graphs were utilized for detecting/predicting single-drug adverse reactions and drug-drug interactions, with variable reported performance and sparse comparisons to legacy methods. Implications: Research to date suggests that knowledge graphs have the potential to augment predictive signal detection in pharmacovigilance, but further research using more reliable reference sets of adverse drug reactions and comparison with legacy pharmacovigilance methods are needed to more clearly define best practices and to establish their place in holistic pharmacovigilance systems.

Introduction: Research on workplace safety has seen significant growth in academic and industry-focused literature over the past 20 years. However, the extant literature on workplace safety tends to focus on safety outcomes of physical accidents and injuries while relegating its conceptual and theoretical development to the background. Psychological safety and psychosocial safety climate in the workplace are essential to workers' health and safety. These concepts are crucial in enabling job satisfaction, work engagement, and performance productivity. Progressing the literature on this subject is necessary to keep abreast with the changing dynamics of the post-COVID challenges, such as working from home, isolation, and stress from AI, among others. A significant gap in the extant literature burrows in the lack of conceptual clarity of workplace safety from a psychological perspective and the poor understanding of its substantive effects on organizations. Hence, re-examining workplace safety's conceptual and theoretical foundations from a psychological lens offers a more nuanced understanding of its potential to contribute to employee well-being and organizational resilience, pursuing a better work-life safe and more comfortable working environment. Method: This study: (a) synthesizes the theoretical propositions and empirical findings from 990 research articles published between 2000 and 2023 to map the existing body of knowledge about psychological safety and psychosocial safety climate, including their theoretical underpinnings and mechanisms, to offer a state-of-the-art overview of the scope of workplace occupational health and safety research from a psychological perspective; (b) applied a data-based research design adhering to PRISMA; (c) compiled descriptive synthesis and textual narrative syntheses through bibliometric analysis and a systematic literature review; and (d) opens the black box of workplace safety research by presenting significant findings to inform future conceptual, theoretical, and methodological research as well as the practice of workplace safety through the lens of psychology. Results: This study's findings further offer managerial implications to workplace safety policy-making and human resource management practices to enhance employees' psychological safety and eliminate workplace psychosocial hazards.

Background: The clinical efficacy and safety of intravenous immunoglobulin (IVIg) treatment for COVID-19 remain controversial. This study aimed to map the current status and gaps of available evidence, and conduct a meta-analysis to further investigate the benefit of IVIg in COVID-19 patients. Methods: Electronic databases were searched for systematic reviews/meta-analyses (SR/MAs), primary studies with control groups, reporting on the use of IVIg in patients with COVID-19. A random-effects meta-analysis with subgroup analyses regarding study design and patient disease severity was performed. Our outcomes of interest determined by the evidence mapping, were mortality, length of hospitalization (days), length of intensive care unit (ICU) stay (days), number of patients requiring mechanical ventilation, and adverse events. Results: We included 34 studies (12 SR/MAs, 8 prospective and 14 retrospective studies). A total of 5571 hospitalized patients were involved in 22 primary studies. Random-effects meta-analyses of very low to moderate evidence showed that there was little or no difference between IVIg and standard care or placebo in reducing mortality (relative risk [RR] 0.91; 95% CI 0.78-1.06; risk difference [RD] 3.3% fewer), length of hospital (mean difference [MD] 0.37; 95% CI - 2.56, 3.31) and ICU (MD 0.36; 95% CI - 0.81, 1.53) stays, mechanical ventilation use (RR 0.92; 95% CI 0.68-1.24; RD 2.8% fewer), and adverse events (RR 0.98; 95% CI 0.84-1.14; RD 0.5% fewer) of patients with COVID-19. Sensitivity analysis using a fixed-effects model indicated that IVIg may reduce mortality (RR 0.76; 95% CI 0.60-0.97), and increase length of hospital stay (MD 0.68; 95% CI 0.09-1.28). Conclusion: Very low to moderate certainty of evidence indicated IVIg may not improve the clinical outcomes of hospitalized patients with COVID-19. Given the discrepancy between the random- and fixed-effects model results, further large-scale and well-designed RCTs are warranted

Intravenous (IV) iron supplementation is the preferred treatment option for managing severe iron deficiency (ID) and ID anemia (IDA). Three of the available IV iron preparations are ferric derisomaltose (FDI), ferric carboxymaltose (FCM), and iron sucrose (IS). The objective of the present work was to review the published literature about the efficacy, safety, quality of life (QoL), and economic outcomes of using FDI, FCM, and IS for the treatment of ID. A systematic literature search was performed following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Eligible studies were assessed for quality using appropriate tools, and data were extracted and analyzed for key outcomes. The evidence synthesis was based on published systematic literature reviews (SLRs), meta-analyses (MAs), indirect treatment comparisons (ITCs), and health technology assessments (HTAs); we also included economic evaluations performed from a Chinese perspective. Out of 337 initial hits, the review included 12 studies. The findings indicated that FDI, FCM, and IS had comparable efficacy in terms of hemoglobin (Hb) improvement. FDI showed a better safety profile with a lower risk of hypophosphatemia, hypersensitivity reactions, and cardiovascular adverse events (AEs) compared to IS and FCM. FDI also demonstrated better cost-effectiveness compared to IS, with potential cost savings attributed to fewer infusions and improved compliance. None of the included studies evaluated QoL after IV iron administration for ID. FDI offers a safe, efficacious, and cost-effective treatment option for ID. It exhibits comparable efficacy to FCM and IS but presents a better safety profile and economic advantage. FDI fulfills the criteria of efficacy, safety, economy, innovation, suitability, and accessibility, making it a promising choice for ID management in China.

Abstract Background: Virtual consultation has been proposed as a promising tool to improve the coordination and quality of healthcare between primary and specialised care. However, despite its potential facilitators, the evidence on the usefulness of virtual consultation for improving healthcare quality domains is fragmented and unclear. This scoping review aims to assess the impact of virtual consultation on different healthcare quality domains. Material and methods: We conducted a scoping review with a rigorous search strategy on PubMed, EMBASE and Cochrane Library databases. The inclusion criteria were original articles, reviews, meta-analyses or letters to the editor, published between 1 January 2017 and 24 June 2022, and available in English, Spanish or French. For each of the articles selected, we identified the addressed healthcare quality domains, their facilitators and barriers, areas of improvement and data gaps. We have adhered to Preferred Reporting Items for Systematic Reviews and Meta-Analyses for Scoping Review reporting standards. Results: 1284 manuscripts were retrieved. Finally, 235 papers were included in this review, most of which were original, descriptive studies. The most evaluated quality domain was effectiveness (223 articles). Safety and patient-centred care were the least evaluated. Simultaneous assessment of more than one domain was observed in 117 papers, being effectiveness and timeliness the most frequent combination. Our analysis revealed that virtual consultation is in development and underused. This tool has the potential to improve access to specialised care and enhance coordination between professionals. Conclusions: Virtual consultation has the potential to provide effective, efficient, equitable and timely attention. However, its contribution to safety and patient-centered care needs further evaluation. Our review emphasises the need for more rigorous research and standardised quality assessment criteria to obtain robust evidence on the usefulness of virtual consultation for improving healthcare quality domains.

BACKGROUND: In the context of a deepening global shortage of health workers and, in particular, the COVID-19 pandemic, there is growing international interest in, and use of, online symptom checkers (OSCs). However, the evidence surrounding the triage and diagnostic accuracy of these tools remains inconclusive. OBJECTIVE: This systematic review aimed to summarize the existing peer-reviewed literature evaluating the triage accuracy (directing users to appropriate services based on their presenting symptoms) and diagnostic accuracy of OSCs aimed at lay users for general health concerns. METHODS: Searches were conducted in MEDLINE, Embase, CINAHL, Health Management Information Consortium (HMIC), and Web of Science, as well as the citations of the studies selected for full-text screening. We included peer-reviewed studies published in English between January 1, 2010, and February 16, 2022, with a controlled and quantitative assessment of either or both triage and diagnostic accuracy of OSCs directed at lay users. We excluded tools supporting health care professionals, as well as disease- or specialty-specific OSCs. Screening and data extraction were carried out independently by 2 reviewers for each study. We performed a descriptive narrative synthesis. RESULTS: A total of 21,296 studies were identified, of which 14 (0.07%) were included. The included studies used clinical vignettes, medical records, or direct input by patients. Of the 14 studies, 6 (43%) reported on triage and diagnostic accuracy, 7 (50%) focused on triage accuracy, and 1 (7%) focused on diagnostic accuracy. These outcomes were assessed based on the diagnostic and triage recommendations attached to the vignette in the case of vignette studies or on those provided by nurses or general practitioners, including through face-to-face and telephone consultations. Both diagnostic accuracy and triage accuracy varied greatly among OSCs. Overall diagnostic accuracy was deemed to be low and was almost always lower than that of the comparator. Similarly, most of the studies (9/13, 69 %) showed suboptimal triage accuracy overall, with a few exceptions (4/13, 31%). The main variables affecting the levels of diagnostic and triage accuracy were the severity and urgency of the condition, the use of artificial intelligence algorithms, and demographic questions. However, the impact of each variable differed across tools and studies, making it difficult to draw any solid conclusions. All included studies had at least one area with unclear risk of bias according to the revised Quality Assessment of Diagnostic Accuracy Studies-2 tool. CONCLUSIONS: Although OSCs have potential to provide accessible and accurate health advice and triage recommendations to users, more research is needed to validate their triage and diagnostic accuracy before widescale adoption in community and health care settings. Future studies should aim to use a common methodology and agreed standard for evaluation to facilitate objective benchmarking and validation.

Background: Although the scientific literature has previously described the impact of worksite programs based on physical activity (WPPAs) on employees' productivity and health in different contexts, the effect of these programs has not been analyzed based on the characteristics or modalities of physical activity (PA) performed (e.g., aerobic exercise, strength training, flexibility). In addition, studies on WPPAs usually report health and productivity outcomes separately, not integrated into a single study. Knowing the health and economic-related impacts of a WPPAs could provide useful information for stakeholders and policy development. Objective: The purpose of this review was as follows: (1) to analyze the effect of different modalities of WPPAs on employees' productivity and health and (2) to investigate the economic impact of WPPAs. Methods: This systematic review is registered in PROSPERO (CRD42021230626) and complies with PRISMA guidelines. Only randomized controlled trials from 1997 to March 2021 were included. Two reviewers independently screened abstracts and full texts for study eligibility, extracted the data, and performed a quality assessment using the Cochrane Collaboration Risk-of-Bias Tool for randomized trials. Population, instruments, comparison, and outcome (PICO) elements were used to define eligibility criteria. Eight-hundred sixty relevant studies were found through electronic searches in PubMed, Web of Science, Medline, Scopus, and SPORTDiscus databases. Once the eligibility criteria were applied, a total of 16 papers were included. Results: Workability was the productivity variable most positively impacted by WPPAs. Cardiorespiratory fitness, muscle strength, and musculoskeletal symptoms health variables improved in all the studies included. It was not possible to fully examine the effectiveness of each exercise modality because of the heterogeneity in methodology, duration, and working population. Finally, cost-effectiveness could not be analyzed because this information was not reported in most studies. Conclusion: All types of WPPAs analyzed improved workers' productivity and health. However, the heterogeneity of WPPAs does not allow to identify which modality is more effective.

BACKGROUND: The Veterans Health Administration (VA) serves Veterans in the nation's largest integrated healthcare system. VA seeks to provide high quality of healthcare to Veterans, but due to the VA Choice and MISSION Acts, VA increasingly pays for care outside of its system in the community. This systematic review compares care provided in VA and non-VA settings, and includes published studies from 2015 to 2023, updating 2 prior systematic reviews on this topic. METHODS: We searched PubMed, Web of Science, and PsychINFO from 2015 to 2023 for published literature comparing VA and non-VA care, including VA-paid community care. Records were included at the abstract or full-text level if they compared VA medical care with care provided in other healthcare systems, and included clinical quality, safety, access, patient experience, efficiency (cost), or equity outcomes. Data from included studies was abstracted by two independent reviewers, with disagreements resolved by consensus. Results were synthesized narratively and via graphical evidence maps. RESULTS: Thirty-seven studies were included after screening 2415 titles. Twelve studies compared VA and VA-paid community care. Most studies assessed clinical quality and safety, and studies of access were second most common. Only six studies assessed patient experience and six assessed cost or efficiency. Clinical quality and safety of VA care was better than or equal to non-VA care in most studies. Patient experience in VA care was better than or equal to experience in non-VA care in all studies, but access and cost/efficiency outcomes were mixed. DISCUSSION: VA care is consistently as good as or better than non-VA care in terms of clinical quality and safety. Access, cost/efficiency, and patient experience between the two systems are not well studied. Further research is needed on these outcomes and on services widely used by Veterans in VA-paid community care, like physical medicine and rehabilitation.

Authors' objectives: Objective The aim of this health technology assessment (HTA) is to evaluate the safety, effectiveness and economic impact of folate testing in an asymptomatic general population and in patients with suspected folate deficiency due to the presence of symptoms, underlying medical disorders or external factors. In addition, ethical, legal, social and organisational issues related to folate testing are investigated.

AIM: To provide an overview of responsibilities and tasks of nurses in pharmaceutical care. DESIGN: Scoping review. METHODS: Two databases were systematically searched (MEDLINE and Scopus) for recent original research papers concerning nurses' responsibilities and tasks in pharmaceutical care. The definition of responsibility was based on literature, moral and ethical discussions. Existing responsibilities and tasks beyond preparation and administration of medication were collected and synthesized. This main study outcome was extracted from titles and abstracts only. Results were reported in accordance with PRISMA-ScR guidelines. RESULTS: Of the 3,805 titles and abstracts reviewed, 453 abstracts were included. A total of seven responsibilities were identified: (a) management of therapeutic and adverse effects of medication, (b) management of medication adherence, (c) management of patient medication self-management, (d) management of patient education and information about medication, (e) prescription management, (f) medication safety management and (g) (transition of) care coordination. Within these responsibilities, all tasks performed by nurses were described.

Background: The coronavirus disease 2019 (COVID-19) continues to spread globally. Due to the higher risk of mortality, the treatment of severe or critical patients is a top priority. Traditional Chinese medicine (TCM) treatment has played an extremely important role in the fight against COVID-19 in China; a timely evidence summary on TCM in managing COVID-19 is crucial to update the knowledge of healthcare for better clinical management of COVID-19. This study aimed to assess the effects and safety of TCM treatments for severe/critical COVID-19 patients by systematically collecting and synthesizing evidence from randomized controlled trials (RCTs) and observational studies (e.g., cohort). Methods: We searched nine databases up to 19th March 2022 and the reference lists of relevant publications. Pairs of reviewers independently screened studies, extracted data of interest, and assessed risk of bias. We performed qualitative systematic analysis with visual presentation of results and compared the direction and distribution of effect estimates for each patient's important outcome. We performed sensitivity analyses to observe the robustness of results by restricting analysis to studies with low risk of bias. Results: The search yielded 217,761 records, and 21 studies (6 RCTs and 15 observational studies) proved eligible. A total of 21 studies enrolled 12,981 severe/critical COVID-19 patients with a mean age of 57.21 years and a mean proportion of men of 47.91%. Compared with usual supportive treatments, the effect estimates of TCM treatments were consistent in direction, illustrating that TCM treatments could reduce the risk of mortality, rate of conversion to critical cases, and mechanical ventilation, and showed significant advantages in shortening the length of hospital stay, time to viral clearance, and symptom resolution. The results were similar when we restricted analyses to low-risk-bias studies. No serious adverse events were reported with TCM treatments, and no significant differences were observed between groups. Conclusion: Encouraging evidence suggests that TCM presents substantial advantages in treating severe/critical COVID-19 patients. TCM has a safety profile that is comparable to that of conventional treatment alone. TCMs have played an important role in China's prevention and treatment of COVID-19, which sets an example of using traditional medicine in preventing and treating COVID-19 worldwide.

BACKGROUND: Previous systematic reviews have found high burnout in healthcare professionals is associated with poorer patient care. However, no review or meta-analysis has investigated this association in surgeons specifically. The present study addressed this gap, by examining the association between surgeon burnout and 1) patient safety and 2) surgical professionalism. METHODS: A systematic review was performed in accordance with PRISMA guidelines. We included original empirical studies that measured burnout and patient care or professionalism in surgeons. Six databases were searched (PsycINFO, Ovid MEDLINE(R), EMBASE, Cochrane Database, CINAHL, and Web of Science) from inception to February 2021. An adapted version of the Cochrane Risk of Bias tool was used to assess study quality. Meta-analysis and narrative synthesis were utilised to synthesise results. RESULTS: Fourteen studies were included in the narrative review (including 27,248 participants) and nine studies were included in the meta-analysis. Burnout was associated with a 2.5-fold increased risk of involvement in medical error (OR = 2.51, 95% Cl [1.68-3.72]). The professionalism outcome variables were too diverse for meta-analysis, however, the narrative synthesis indicated a link between high burnout and a higher risk of loss of temper and malpractice suits and lower empathy. No link was found between burnout and patient satisfaction. CONCLUSION: There is a significant association between higher burnout in surgeons and poorer patient safety. The delivery of interventions to reduce surgeon burnout should be prioritised; such interventions should be evaluated for their potential to produce concomitant improvements in patient safety.

OBJECTIVES: Wearing a mask is an important method for reducing severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) transmission in health care and public safety settings. We assess the evidence regarding masking in the workplace during the initial months of the COVID-19 pandemic (PROSPERO CRD4202432097). METHODS: We performed a systematic review of published literature from 4 databases and evaluated the quality of evidence with the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) framework. We searched for observational and experimental research involving public safety and health care workers. We included articles evaluating the use of masks, versus no mask, on the outcome of SARS-CoV-2 infection. RESULTS: Our search yielded 15,013 records, of which 9 studies were included. Most studies (n = 8; 88.9%) involved infections or outbreaks among health care workers. The majority (88.9%) used in-depth interviews of cases and non-cases to obtain self-reported use of masks during periods of exposure. One of 9 studies quantitatively assessed differences in SARS-CoV-2 infection based on use of masks in non-patient care settings. Use of observational study designs, small sample sizes, inadequate control for confounding, and inadequate measurement of exposure and non-exposure periods with infected coworkers contributed to the quality of evidence being judged as very low. CONCLUSIONS: The available evidence from the initial months of the pandemic suggests that the use of masks in congregate, non-patient care settings, such as breakrooms, helps to reduce risk of SARS-CoV-2 virus transmission. However, this evidence is limited and is of very low quality. Prospective studies incorporating active observation measures are warranted.
