RESUMO
BACKGROUND: Racial disparities in lung cancer screening (LCS) are well established. Black Veterans are among those at the highest risk for developing lung cancer but are less likely to complete LCS. We sought to identify barriers and facilitators to LCS uptake among Black Veterans. PATIENTS AND METHODS: A qualitative study using semistructured interviews was conducted with 32 Black Veterans to assess for barriers, facilitators, and contextual factors for LCS and strategies to improve screening. Veterans were purposively sampled by age, sex, and LCS participation status (ie, patients who received a low-dose CT [LDCT], patients who contacted the screening program but did not receive an LDCT, and patients who did not connect with the screening program nor receive an LDCT). Interview guides were developed using the Theoretical Domains Framework and Health Belief Model. Data were analyzed using rapid qualitative analysis. RESULTS: Barriers of LCS uptake among Black Veterans include self-reported low LCS knowledge and poor memory, attention, and decision processes associated with the centralized LCS process. Facilitators of LCS uptake among Black Veterans include social/professional role; identity and social influences; perceived susceptibility, threat, and consequences due to smoking status and military or occupational exposures; emotion, behavioral regulation, and intentions; and high trust in providers. Environmental context and resources (eg, transportation) and race and racism serve as contextual factors that did not emerge as having a major impact on LCS uptake. Strategies to improve LCS uptake included increased social messaging surrounding LCS, various forms of information dissemination, LCS reminders, balanced and repeated shared decision-making discussions, and streamlined referrals. CONCLUSIONS: We identified addressable barriers and facilitators for LCS uptake among Black Veterans that can help focus efforts to improve disparities in screening. Future studies should explore provider perspectives and test interventions to improve equity in LCS.

Lung cancer screening (LCS) decreases lung cancer related mortality among high-risk people who smoke cigarettes and has been endorsed by the US Preventive Services Task Force (USPSTF) since 2013. However, adoption of LCS has been limited, and disparities in LCS among racially and ethnically minoritized groups have become apparent. While recommendations to improve disparities in LCS have been made, there is a lack of information on how these recommendations have been implemented and their relative effectiveness in improving screening disparities. This scoping review addresses this knowledge gap by examining interventions that have been implemented to improve LCS among racially and ethnically minoritized groups in the United States. A comprehensive search of MEDLINE (via PubMed), EMBASE (via Elsevier), CINAHL Complete (via EBSCO), and Scopus (via Elsevier), for articles from the period 1 January 2010 through 22 October 2021 was completed. Out of 17,045 references screened, only 11 studies describing an intervention to improve disparities in LCS were identified, underscoring the dearth of data on established interventions. The interventions discussed could be categorized into three groups -- patient level (n = 3), clinic/institution level (n = 3), and community level (n = 5) interventions. Of those studies reporting effectiveness data (n = 8), there was substantial heterogeneity in the outcomes measured and their relative effectiveness. We found that interventions which streamlined the LCS process at the level of a single clinic or institution were the most effective in improving LCS. Community-level interventions that focused on engagement and education had the greatest potential to target racially and ethnically minoritized groups. Our study underscores the need for more robust research on addressing barriers to LCS by identifying effective patient, clinic, and community-level interventions to improve LCS disparities and the need for potential standardization of intervention effectiveness outcomes.

Background: Carbon monoxide (CO) is an endogenous signaling molecule that activates cytoprotective programs implicated in the resolution of acute respiratory distress syndrome (ARDS) and survival of critical illness. Because CO levels can be measured in blood as carboxyhemoglobin, we hypothesized that carboxyhemoglobin percent (COHb%) may associate with mortality. OBJECTIVES: To examine the relationship between COHb% and outcomes in patients with ARDS requiring venovenous extracorporeal membrane oxygenation (ECMO), a condition where elevated COHb% is commonly observed. DESIGN: Retrospective cohort study. SETTING: Academic medical center ICU. PATIENTS: Patients were included that had ARDS on venovenous ECMO. MEASUREMENTS AND MAIN RESULTS: We examined the association between COHb% and mortality using a Cox proportional hazards model. Secondary outcomes including ECMO duration, ventilator weaning, and hospital and ICU length of stay were examined using both subdistribution and causal-specific hazard models for competing risks. We identified 109 consecutive patients for analysis. Mortality significantly decreased per 1 U increase in COHb% below 3.25% (hazard ratio [HR], 0.35; 95% CI, 0.15-0.80; p = 0.013) and increased per 1 U increase above 3.25% (HR, 4.7; 95% CI, 1.5-14.7; p = 0.007) reflecting a nonlinear association (p = 0.006). Each unit increase in COHb% was associated with reduced likelihood of liberation from ECMO and mechanical ventilation, and increased time to hospital and ICU discharge (all p < 0.05). COHb% was significantly associated with hemolysis but not with initiation of hemodialysis or blood transfusions. CONCLUSIONS: In patients with ARDS on venovenous ECMO, COHb% is a novel biomarker for mortality exhibiting a U-shaped pattern. Our findings suggest that too little CO (perhaps due to impaired host signaling) or excess CO (perhaps due to hemolysis) is associated with higher mortality. Patients with low COHb% may exhibit the most benefit from future therapies targeting anti-oxidant and anti-inflammatory pathways such as low-dose inhaled CO gas.
RESUMO
A transgender man in his late teens presented with signs of multisystem disease, including hepatitis, mucositis and bone marrow suppression. He later developed dyspnoea, leucocytosis and bilateral pulmonary infiltrates on chest radiograph. He was treated for community-acquired pneumonia. After several days of treatment, he developed hypoxaemic respiratory failure due to bronchoscopy-confirmed diffuse alveolar haemorrhage (DAH). The differential diagnosis and workup were extensive, and he was ultimately treated with intravenous steroids and five sessions of plasmapheresis for a presumed autoimmune aetiology. Investigations were remarkable only for elevated IgM and IgG to Mycoplasma pneumoniae (MP). This case represents a rare presentation of multisystem disease secondary to MP in adults. Clinicians should consider Mycoplasma infection in cases of multisystem disease and observe for DAH even after initiation of appropriate therapy.

The authors present a tool to improve gaps in patient safety using the electronic health record. The tool integrates gap identification, passive alerts, and actions into a single interface embedded within clinicians' workflow. The tool was developed to address venous thromboembolism prophylaxis, prevention of hypo- and hyperglycemia, code status documentation, bowel movement frequency, and skilled nursing facility transitions. Alerts and actions during silent and live periods were retrospectively analyzed. The most prevalent safety gaps were lack of venous thromboembolism prophylaxis (40.4% of alerts), constipation (19.3%), and lack of code status (18.4%). Disparities in safety gaps were present by patient race, sex, and socioeconomic status. Usability testing showed positive feedback without significant alert burden. Thus, a safety gap tool was successfully built to study and address patient safety issues. The tool's strengths are its integration within the electronic health record, ease of use, customizability, and scalability.

Administration of the birth dose of hepatitis B vaccine is an important step in reducing perinatally acquired hepatitis B infection, yet the USA is below the Healthy People 2020 goal for rate of administration.In response to updated Advisory Committee on Immunisation Practices recommendations to administer the dose within 24 hours of birth, we used quality improvement methodology to implement changes that would increase the vaccination rates of healthy newborns in our nurseries. The goal was to improve the proportion of infants who receive the hepatitis B vaccine within 24 hours of birth to >90% within a 2-year period, with a secondary goal of increasing vaccination rates prior to discharge from the nursery to >95%.Multiple Plan-Do-Study-Act (PDSA) cycles were performed. Initial cycles focused on increasing nurse and provider awareness of the updated timing recommendations. Later cycles targeted nursing workflow to facilitate timely administration of the vaccine. We implemented changes at our university medical centre and community hospital newborn nurseries.At the university medical centre nursery, both primary and secondary goals were met; the rate of hepatitis B vaccine administration within 24 hours increased from 81.7% to 96.2%, with vaccine administration prior to discharge increasing from 93.4% to 97.9%. In the community hospital nursery, the baseline rate of hepatitis B vaccine administration within 24 hours was 78.1%, and this increased to 85.8% with the interventions, falling short of the target of >90%. Vaccine administration prior to discharge increased from 87.2% to 92.0%, also not meeting the secondary target of 95%.Interventions that facilitated workflow had additional benefit beyond education alone to improve timing and rates of hepatitis B vaccine administration in both a university medical centre and community hospital nursery.
