Objective: Although frontline clinicians are crucial in implementing and spreading innovations, their engagement in quality improvement remains suboptimal. Our goal was to identify facilitators and barriers to the development and engagement of clinicians in quality improvement.Design: A 25-item questionnaire informed by theoretical frameworks was developed, tested and disseminated by email.Settings: Members and fellows of the International Society for Quality in Healthcare.Participants: 1010 eligible participants (380 fellows and 647 members).Interventions: None.Main Outcome Measures: Self-efficacy and effectiveness in conducting and leading quality improvement activities.Results: We received 212 responses from 50 countries, a response rate of 21%. Dedicated time for quality improvement, mentorship and coaching and a professional quality improvement network were significantly related to higher self-efficacy. Factors enhancing effectiveness were dedicated time for quality improvement, multidisciplinary improvement teams, professional development in quality improvement, ability to select areas for improvement and organizational values and culture. Inadequate time, mentorship, organizational support and access to professional development resources were key barriers. Personal strengths contributing to effectiveness were the ability to identify problems that need to be fixed, reflecting on and learning from experiences and facilitating sharing of ideas. Key quality improvement implementation challenges were adopting new payment models, demonstrating the business case for quality and safety and building a culture of accountability and transparency.Conclusions: Our findings highlight areas that organizations and professional development programs should focus on to promote clinician development and engagement in quality improvement. Barriers related to training, time, mentorship, organizational support and implementation must be concurrently addressed to augment the effectiveness of other approaches. [ABSTRACT FROM AUTHOR]

Background: After Action Review is a form of facilitated team learning and review of events. The methodology originated in the United States Army and forms part of the Incident Management Framework in the Irish Health Services. After Action Review has been hypothesized to improve safety culture and the effect of patient safety events on staff (second victim experience) in health care settings. Yet little direct evidence exists to support this and its implementation has not been studied. Aim: To investigate the effect of After Action Review on safety culture and second victim experience and to examine After Action Review implementation in a hospital setting. Methods: A mixed methods study will be conducted at an Irish hospital. To assess the effect on safety culture and second victim experience, hospital staff will complete surveys before and twelve months after the introduction of After Action Review to the hospital (Hospital Survey on Safety Culture 2.0 and Second Victim Experience and Support Tool). Approximately one in twelve staff will be trained as After Action Review Facilitators using a simulation based training programme. Six months after the After Action Review training, focus groups will be conducted with a stratified random sample of the trained facilitators. These will explore enablers and barriers to implementation using the Theoretical Domains Framework. At twelve months, information will be collected from the trained facilitators and the hospital to establish the quality and resource implications of implementing After Action Review. Discussion: The results of the study will directly inform local hospital decision-making and national and international approaches to incorporating After Action Review in hospitals and other healthcare settings.

Background: The density and phenotype of tumour-associated macrophages have been linked with prognosis in a range of solid tumours. While there is strong preclinical evidence that tumour-associated macrophages promote aspects of tumour progression, it can be challenging to infer clinical activity from surface markers and ex vivo behaviour. We investigated the association of macrophage infiltration with prognosis and functional changes in the tumour microenvironment in primary human melanoma.Methods: Fifty-seven formalin-fixed, paraffin-embedded primary melanomas were analysed by immunohistochemical analysis of CD68, CD163, inducible nitric oxide synthase (iNOS) and arginase expression. RNA sequencing was performed on serial sections of 20 of the stained tumours to determine the influence of macrophage infiltration on gene expression.Results: CD68+ cells are a functionally active subset of macrophages that are associated with increased iNOS and arginase staining and altered gene expression. In comparison, while there is a greater accumulation of CD163+ macrophages in larger tumours, these cells are comparatively inactive, with no association with the level of iNOS or arginase staining, and no effect on gene expression within the tumour. The infiltration of either subset of macrophages did not correlate to overall survival.Conclusions: Thus, melanomas contain distinct macrophage populations with diverse phenotypes, but with no observable prognostic role.

In summary, we report a follow-up study of a small cohort of latex-allergic patients, and demonstrate a proportion of patients whose investigations no longer indicate latex allergy following a period of allergen avoidance. Keywords: contact urticaria; occupational; rubber chemicals EN contact urticaria occupational rubber chemicals 451 452 2 05/06/21 20210601 NES 210601 Natural rubber latex (NRL) allergy is an important occupational health concern, particularly among healthcare professionals (HCPs). Half of the patients (n = 10) had changed occupation since diagnosis, but only three patients reported latex allergy as the reason for change. [Extracted from the article]

Molecular methods may reveal the presence of pathogens in samples through the detection of specific target gene(s) associated with microorganisms, but often, the subsequent cultural isolation of the pathogen is not possible. This discrepancy may be related to low concentration of the cells, presence of dead cells, competitive microflora, injured cells and cells in a viable but non-culturable state, free DNA and the presence of free bacteriophages which can carry the target gene causing the PCR-positive/culture-negative results. Shiga-toxigenic Escherichia coli (STEC) was used as a model for studying this phenomenon, based on the phage-encoded cytotoxins genes (Stx family) as the detection target in samples through real-time qPCR. Stx phages can be integrated in the STEC chromosome or can be isolated as free particles in the environment. In this study, a combination of PCR with culturing was used for investigating the presence of the stx1 and stx2 genes in 155 ovine recto-anal junction swab samples (method (a)-PCR). Samples which were PCR-positive and culture-negative were subjected to additional analyses including detection of dead STEC cells (method (b)-PCR-PMA dye assay), presence of Stx phages (method (c)-plaque assays) and inducible integrated phages (method (d)-phage induction). Method (a) showed that even though 121 samples gave a PCR-positive result (78%), only 68 samples yielded a culturable isolate (43.9%). Among the 53 (34.2%) PCR-positive/culture-negative samples, 21 (39.6%) samples were shown to have STEC dead cells only, eight (15.1%) had a combination of dead cells and inducible stx phage, while two samples (3.8%) had a combination of dead cells, inducible phage and free stx phage, and a further two samples had Stx1 free phages only (3.8%). It was thus possible to reduce the samples with no explanation to 20 (37.7% of 53 samples), representing a further step towards an improved understanding of the STEC PCR-positive/culture-negative phenomenon.
