We surveyed physicians and patients to create a novel Desirability of outcome ranking (DOOR) for non-severe community-acquired pneumonia (CAP). Patients generally ranked uncomfortable but non-life-threatening symptoms as less desirable, while physicians focused on traditional medical outcomes. When developing DOORs, both patient and clinician perspectives should be considered.

Paleontology provides insights into the history of the planet, from the origins of life billions of years ago to the biotic changes of the Recent. The scope of paleontological research is as vast as it is varied, and the field is constantly evolving. In an effort to identify “Big Questions” in paleontology, experts from around the world came together to build a list of priority questions the field can address in the years ahead. The 89 questions presented herein (grouped within 11 themes) represent contributions from nearly 200 international scientists. These questions touch on common themes including biodiversity drivers and patterns, integrating data types across spatiotemporal scales, applying paleontological data to contemporary biodiversity and climate issues, and effectively utilizing innovative methods and technology for new paleontological insights. In addition to these theoretical questions, discussions touch upon structural concerns within the field, advocating for an increased valuation of specimen-based research, protection of natural heritage sites, and the importance of collections infrastructure, along with a stronger emphasis on human diversity, equity, and inclusion. These questions offer a starting point—an initial nucleus of consensus that paleontologists can expand on—for engaging in discussions, securing funding, advocating for museums, and fostering continued growth in shared research directions.

Respiratory viral infection (RVI) outbreaks pose a significant threat to health. They are associated with patient morbidity and mortality, staff absenteeism, and financial burden on the healthcare system. There is a need for strategies to reduce RVI transmission in hospitals. One proposal is implementation of continuous masking policies. However, the effectiveness of such policies in mitigating RVI spread is unclear. We conducted a systematic review of the literature to determine the effectiveness of continuous masking in reducing the incidence and transmission of RVIs amongst patients and healthcare workers (HCWs) in hospitals. We systematically searched for original articles published between 2000-2024 according to a pre-determined search criterion. Studies were screened by two reviewers in Covidence. One reviewer extracted the data from eligible studies into a pre-determined data extraction form. For studies that reported only count data, results were summarized narratively. Meta-analysis to pool unadjusted or adjusted outcome measures for studies that report a statistical comparison between masking policies and transmission of infections will be considered if appropriate. Joanna Briggs Institute tools will be used for critical appraisal. 3691 studies were identified. 17 met eligibility criteria. 12 studies were conducted in single-center adult hospitals. 4 studies were conducted in pediatric hospitals, with 2 in neonatal centers. One study was conducted on a hospital system. The studied infections were influenza A/B, parainfluenza 1-3, adenovirus, respiratory syncytial virus (RSV), traditional human coronavirus strains, human metapneumovirus, SARS-CoV-2, and rhinovirus/enterovirus. Eight studies assessed the impact of a masking policy on infection rate in patients. All 8 reported masking policies reduce RVI transmission in patients. 9 studies assessed the impact of a masking policy on infection rate in HCWs. 7 were associated with reductions in RVI transmission in HCWs, whereas 2 showed no statistically significant change. The studies identified in this systematic review were associated with a reduction in RVI transmission with the use of continuous masking amongst patients. The evidence for continuous masking was less consistent for preventing RVI transmission amongst HCW with two studies reporting it was not effective. Our findings suggest that masking policies may play a role in RVI prevention but there are significant limitations with the use of observational design and masking in conjunction with other prevention measures. However, assessment of the quality of the papers is pending. Future directions will include assessing secondary outcomes like masking adherence and assessing adjusted analyses form confounding which are critically important.

Background: Adherence with antimicrobial resistant organism (ARO) admission screening is suboptimal, despite clinical support tools in clinical information systems (CIS) to facilitate the process. Behaviour change techniques to improve adherence are needed. However, in a resource-constrained healthcare system, strategies that motivate healthcare workers (HCWs) to align their practices with infection prevention and control (IPC) policies need to be prioritized. Methods: An online survey (REDCap) and a virtual (Zoom) consensus meeting using a modified nominal group technique with online voting was conducted among HCWs, IPC, and the CIS staff in September and October 2024, respectively, to achieve consensus on a prioritized list of interventions to improve ARO admission screening at acute care and acute rehabilitation facilities (n=100) in Alberta, Canada. Interventions from the Behaviour Change Wheel were mapped to barriers/enablers influencing screening adherence. Each intervention was judged across the APEASE criteria (Acceptability, Practicality, Effectiveness, Affordability, Side Effects, Equity) using a 5-point Likert Scale. Consensus to include interventions required >4 criteria with >80% agreement, consensus to exclude required >4 criteria with 80%. Interventions that did not reach consensus were discussed to determine whether to include in the final candidate list. Attendees were asked to vote on their top three interventions from the final candidate list. Results: There were 15 barriers and one enabler to ARO admission screening, mapped to 43 unique interventions. Of these, 16 interventions addressed more than one barrier/enabler, while 27 interventions only addressed a single barrier. Fifty-nine respondents completed the survey. Most respondents (63%) were IPC staff, 20% were nurses, and 17% were other HCWs (including IPC physicians). Nine interventions met criteria to include in the candidate list, 26 were excluded, and 8 interventions did not reach consensus in the survey and were discussed. There were 32 attendees at the consensus meeting (53% IPC staff and physicians, 34% clinical staff, 13% other provincial teams). Three interventions were selected: 1) creating a nursing task to complete the tool in the CIS when an admission order is signed, 2) add a banner on the CIS Storyboard when the tool is not complete, and 3) develop a best practice guideline for frontline staff on ARO admission screening. Conclusions: The survey and consensus meeting were efficient methods to determine a prioritized list of interventions, which will be implemented and evaluated, to improve ARO admission screening in Alberta.

Background: Dichotomous outcomes rarely capture the range of potential outcomes important to patients and clinicians. To address this limitation, the Desirability of Outcome Ranking (DOOR) score was created to rank potential outcomes from least to most desirable. Currently, there is no standardized method to develop a DOOR score and data are limited on whether patients and their clinicians rank outcomes similarly. We aimed: (a) to develop a novel DOOR score for adults hospitalized with community-acquired pneumonia (CAP) by surveying patients and clinicians on their preferred outcome ranking and (b) to compare their relative DOOR rankings. Methods: We created nine clinical scenarios describing the spectrum of potential outcomes of patients with CAP two weeks after initial emergency department visit. To ascertain clinician DOOR score, we used a snowball sampling method to recruit a target of 25 clinicians in specialties that regularly treat CAP. For the patient DOOR score, we recruited patients hospitalized with CAP by reviewing electronic patient lists for adults hospitalized with pneumonia. Respondents were asked to rank the 9 cases from most to least desirable in REDCap. To create the final DOOR score, we used Friedman rank sum tests to combine/collapse DOOR outcomes with scores that did not significantly differ. We used the Mann Whitney U test to compare DOOR rankings between physicians and patients. Final study results were presented to a national hospital medicine patient and family advisory committee (PFAC) for their impressions. Results: 22 patients (71% response rate) and 25 clinicians responded to our DOOR survey. Their ranked order of DOOR outcomes is shown in Table 1. Combining non-significantly different DOOR outcomes resulted in collapsing of 6 cases into 2 categories for 5 overall DOOR scores that significantly differed from each other (Table 1 for final ranking). Patients and clinicians had significantly different preferred ranking for 6 DOOR cases. Our PFAC had several hypotheses as to why rankings differed (Table 2). Conclusion: We present a novel DOOR score derived from patient and clinician reported preferences for outcomes of hospitalized adult patients with CAP. Clinicians and patients differed in their perception of certain outcomes with patients ranking symptoms that were uncomfortable but not potentially life-threatening as less desirable than physicians. Physicians tended to rank quality linked metrics such as readmission as worse than patients. When designing future trials using DOOR scores, researchers should consider including patients in DOOR score design as their perspectives may differ from clinicians.

Background: Targeted admission screening of high-risk patients for antimicrobial resistant organisms (AROs) is a key component of infection prevention and control. However, adherence with screening is suboptimal, risking a negligible impact on the prevention of ARO transmission. Clinical decision support tools in clinical information systems (CIS) may improve ARO screening adherence. This study evaluated the adherence of ARO admission screening using a tool in the provincial CIS in Alberta, Canada and the relationship between adherence and hospital ARO rates. Methods: A population-based, sequential cross-sectional study was completed on all admissions to acute care and acute rehabilitation facilities where ARO admission screening occurs on any unit, and where the CIS was implemented in Alberta between January 1, 2020 and March 31, 2024 (n=100). Mental health facilities/units, continuing care, newborns Results: There were 97 (97% of eligible facilities) facilities that implemented the CIS across seven launch periods included. Overall adherence ranged from 43% to 65%. After controlling for bed size and health zone, adherence decreased by the number of months each facility was active on the CIS (aIRR 0.987, 95%CI 0.986-0.987). There was no seasonality in trends. There was a negative relationship between adherence and overall MRSA infection rate (rs = -0.68) and after adjusting for bed size, health zone, and number of months active on the CIS (aIRR 0.99, 95% CI 0.986-0.994). Analysis could not be completed for CPO due to small numbers. Conclusions: While increased ARO admission screening adherence was associated with lower overall MRSA infection rates, the IRR was close to one and may not be clinically significant. With adherence decreasing over time, further work is needed to understand barriers to ARO admission screening and implement strategies to support healthcare providers in completing appropriate surveillance for AROs.

This study investigates screening practices for antimicrobial-resistant organisms (AROs) in seventy-five hospitals participating in the Canadian Nosocomial Infection Surveillance Program (CNISP). Screening practices varied with widespread MRSA screening, selective carbapenemase-producing organisms (CPO) screening, and limited vancomycin-resistant Enterococcus (VRE) screening. These findings may help interpret ARO rates within CNISP hospitals and inform screening practices.

When making decisions, people tend to look back and forth between the alternatives until they eventually make a choice. Eye-tracking research has established that these shifts in attention are strongly linked to choice outcomes. A predominant framework for understanding the dynamics of the choice process, and thus the effects of attention, is sequential sampling of information. However, existing methods for estimating the attention parameters in these models are computationally costly and overly flexible, and yield estimates with unknown precision and bias. Here we propose an estimation method that relies on a link between sequential sampling models and random utility models (RUM). This method uses familiar econometric tools (i.e., logistic regression) and yields estimates that appear to be unbiased and relatively precise compared to existing methods, in a small fraction of the computation time. The RUM thus appears to be a useful tool for estimating the effects of attention on choice.

Evidence-based insertion and maintenance bundles are effective in reducing the incidence of central line-associated bloodstream infections (CLABSI) in intensive care unit (ICU) settings. We studied the adoption and compliance of CLABSI prevention bundle programs and CLABSI rates in ICUs in a large network of acute care hospitals across Canada.

The conservation sector increasingly values reflexivity, in which professionals critically reflect on the social, institutional and political aspects of their work. Reflexivity offers diverse benefits, from enhancing individual performance to driving institutional transformation. However, integrating reflexivity into conservation practice remains challenging and is often confined to informal reflections with limited impact. To overcome this challenge, we introduce co-reflexivity, offering an alternative to the binary distinction between social science on or for conservation, which respectively produce critical outsider accounts of conservation or provide social science instruments for achieving conservation objectives. Instead, co-reflexivity is a form of social science with conservation, in which conservation professionals and social scientists jointly develop critical yet constructive perspectives on and approaches to conservation. We demonstrate the value of co-reflexivity by presenting a set of reflections on the project model, the dominant framework for conservation funding, which organizes conservation activity into distinct, target-oriented and temporally bounded units that can be funded, implemented and evaluated separately. Co-reflexivity helps reveal the diverse challenges that the project model creates for conservation practice, including for the adoption of reflexivity itself. Putting insights from social science research in dialogue with reflections from conservation professionals, we co-produce a critique of project-based conservation with both theoretical and practical implications. These cross-disciplinary conversations provide a case study of how co-reflexivity can enhance the conservation–social science relationship.

During their northward migration, Red Knots Calidris canutus rufa stop at the Lagoa do Peixe National Park in the extreme south of Brazil to build up fat reserves for their journey to their Canadian breeding grounds. We tracked five Red Knots with PinPoint Argos-75 GPS transmitters to investigate differences in migration strategies from this stopover. Tracked birds used two different routes: the Central Brazil route and the Brazilian Atlantic Coast route. One bird flew 8,300 km straight from Lagoa do Peixe to the Delaware Bay (USA). Another bird stopped in Maranhão (north-east Brazil) and a third one used a yet unknown environment for the species, the mouth of the Amazon River at Baía Santa Rosa, Brazil. These two birds made short flights, covering stretches of 1,600 km to 3,600 km between stop-overs, where they stayed from 4 to 18 days. Our study highlights the occurrence of intrapopulation variation in migratory strategies and reveals the connectivity of environments that are essential for the viability of rufa Red Knot populations.
