Importance: Few person-centered, scalable models of collaborative intensive care unit (ICU) clinician-palliative care specialist care exist.

Objective: To evaluate the effect of a collaborative palliative care intervention compared to usual care among family members of patients in the ICU.

Design, Setting, And Participants: This parallel-group randomized clinical trial with patient-level randomization was conducted between April 2021 and September 2023.

In the United States, Black and Latino children with asthma are more likely than White children with asthma to require emergency department visits or hospitalizations because of an asthma exacerbation. Although many cite patient-level socioeconomic status and access to health care as primary drivers of disparities, there is an emerging focus on a major root cause of disparities-systemic racism. Current conceptual models of asthma disparities depict the historical and current effects of systemic racism as the foundation for unequal exposures to social determinants of health, environmental exposures, epigenetic factors, and differential healthcare access and quality.

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.

Importance: Unmet and racially disparate palliative care needs are common in intensive care unit (ICU) settings.

Objective: To test the effect of a primary palliative care intervention vs usual care control both overall and by family member race.

Design, Setting, And Participants: This cluster randomized clinical trial was conducted at 6 adult medical and surgical ICUs in 2 academic and community hospitals in North Carolina between April 2019 and May 2022 with physician-level randomization and sequential clusters of 2 Black patient-family member dyads and 2 White patient-family member dyads enrolled under each physician.

Article Synopsis
  • Racial disparities in lung cancer screening (LCS) exist within the Veterans Affairs health care system, despite reduced barriers; a study at the Durham Veterans Affairs Health Care System aimed to investigate this issue in North Carolina.
  • The study included veterans referred for LCS from 2013 to 2021, specifically looking at those who identified as White or Black and met eligibility criteria, excluding those who died early or screened before referral.
  • Results showed that only 37.1% of veterans completed LCS, with significant disparities: Black veterans had a lower completion rate (30.5%) compared to White veterans (41.3%), and lower odds of completing screening even after accounting for demographic and socioeconomic factors.

Objectives: While palliative care needs are assumed to improve during ICU care, few empiric data exist on need trajectories or their impact on long-term outcomes. We aimed to describe trajectories of palliative care needs during ICU care and to determine if changes in needs over 1 week was associated with similar changes in psychological distress symptoms at 3 months.

Design: Prospective cohort study.

Objective: Because the heterogeneity of patients in intensive care units (ICUs) and family members represents a challenge to palliative care delivery, we aimed to determine if distinct phenotypes of palliative care needs exist.

Methods: Prospective cohort study conducted among family members of adult patients undergoing mechanical ventilation in six medical and surgical ICUs. The primary outcome was palliative care need measured by the Needs at the End-of-Life Screening Tool (NEST, range from 0 (no need) to 130 (highest need)) completed 3 days after ICU admission.

Article Synopsis
  • Black and Latinx adults with moderate-to-severe asthma were involved in a trial comparing a patient-activated inhaled glucocorticoid strategy (intervention) against usual care to address high asthma burdens in these populations.
  • The results showed that the intervention group experienced fewer severe asthma exacerbations (0.69 vs. 0.82) and improved asthma control over time compared to the usual-care group.
  • The intervention also led to a reduction in missed days due to asthma, enhancing participants' quality of life and indicating a potential benefit for tailored asthma management strategies in these communities.

Importance: Palliative care consultations in intensive care units (ICUs) are increasingly prompted by clinical characteristics associated with mortality or resource utilization. However, it is not known whether these triggers reflect actual palliative care needs.

Objective: To compare unmet needs by clinical palliative care trigger status (present vs absent).

Introduction: The technologies used to treat the millions who receive care in intensive care unit (ICUs) each year have steadily advanced. However, the quality of ICU-based communication has remained suboptimal, particularly concerning for Black patients and their family members. Therefore we developed a mobile app intervention for ICU clinicians and family members called ICUconnect that assists with delivering need-based care.

Asthma prevalence, morbidity, and mortality disproportionately impact African American/Black (AA/B) and Hispanic/Latinx (H/L) communities. Adherence to daily inhaled corticosteroid (ICS), recommended by asthma guidelines in all but the mildest cases of asthma, is generally poor. As-needed ICS has shown promise as a patient-empowering asthma management strategy, but it has not been rigorously studied in AA/B or H/L patients or in a real-world setting.

Background: Internationally, adult asthma medication adherence rates are low. Studies characterizing variations in barriers by country are lacking.

Objective: To conduct a scoping review to characterize international variations in barriers to asthma medication adherence among adults.

Background: Cluster-randomized trials (CRTs) are being increasingly used to test a range of interventions, including medical interventions commonly used in clinical practice. Policies created by the NIH and the Food and Drug Administration (FDA) require the reporting of demographics and the examination of demographic heterogeneity of treatment effect (HTE) for individually randomized trials. Little is known about how frequent demographics are reported and HTE analyses are conducted in CRTs.

Background: Inhaled corticosteroid (ICS) adherence rates are suboptimal among adult black/African Americans. Comprehensive studies characterizing the effectiveness and the methodological approaches to the development of interventions to improve ICS adherence in adult black/African Americans have not been performed.

Objectives: Conduct a systematic review of patient/family-level interventions to improve ICS adherence in adult black/African Americans.

Background/aims The Food and Drug Administration Amendments Act mandates that applicable clinical trials report basic summary results to the ClinicalTrials.gov database within 1 year of trial completion or termination. We aimed to determine the proportion of pulmonary trials reporting basic summary results to ClinicalTrials.

The global burden of chronic obstructive pulmonary disease (COPD) continues to grow in part due to better outcomes in other major diseases and in part because a substantial portion of the worldwide population continues to be exposed to inhalant toxins. However, a disproportionate burden of COPD occurs in people of low socioeconomic status (SES) due to differences in health behaviors, sociopolitical factors, and social and structural environmental exposures. Tobacco use, occupations with exposure to inhalant toxins, and indoor biomass fuel (BF) exposure are more common in low SES populations.

Objective: We assessed the sensitivity and specificity of 8 electronic health record (EHR)-based phenotypes for diabetes mellitus against gold-standard American Diabetes Association (ADA) diagnostic criteria via chart review by clinical experts.

Materials And Methods: We identified EHR-based diabetes phenotype definitions that were developed for various purposes by a variety of users, including academic medical centers, Medicare, the New York City Health Department, and pharmacy benefit managers. We applied these definitions to a sample of 173 503 patients with records in the Duke Health System Enterprise Data Warehouse and at least 1 visit over a 5-year period (2007-2011).
