BACKGROUND:Clinical screening for basic social needs—such as food and housing insecurity—is becoming more common as health systems develop programs to address social determinants of health. Clinician attitudes toward such programs are largely unexplored.
OBJECTIVE:To describe the attitudes and experiences of social needs screening among a variety of clinicians and other health care professionals.
RESEARCH DESIGN:Multicenter electronic and paper-based survey.
SUBJECTS:Two hundred fifty-eight clinicians including primarily physicians, social workers, nurses, and pharmacists from a large integrated health system in Southern California.
MEASURES:Level of agreement with prompts exploring attitudes toward and barriers to screening and addressing social needs in different clinical settings.
RESULTS:Overall, most health professionals supported social needs screening in clinical settings (84%). Only a minority (41%) of clinicians expressed confidence in their ability to address social needs, and less than a quarter (23%) routinely screen for social needs currently. Clinicians perceived lack of time to ask (60%) and resources (50%) to address social needs as their most significant barriers. We found differences by health profession in attitudes toward and barriers to screening for social needs, with physicians more likely to cite time constraints as a barrier.
CONCLUSIONS:Clinicians largely support social needs programs, but they also recognize key barriers to their implementation. Health systems interested in implementing social needs programs should consider the clinician perspective around the time and resources required for such programs and address these perceived barriers.

Patients’ Attitudes and Perceptions Regarding Social Needs Screening and Navigation: Multi-site Survey in a Large Integrated Health System
2020
BackgroundAs more health care organizations integrate social needs screening and navigation programs into clinical care delivery, the patient perspective is necessary to guide implementation and achieve patient-centered care.ObjectivesTo examine patients’ perceptions of whether social needs affect health and attitudes toward healthcare system efforts to screen for and address social needs.Research DesignMulti-site, self-administered survey to assess (1) patient perceptions of the health impact of commonly identified social needs; (2) experience of social needs; (3) degree of support for a health system addressing social needs, including which social needs should be screened for and intervened upon; and (4) attitudes toward a health system utilizing resources to address social needs. Analyses were conducted using multivariable logistic regression models with clinic site cluster adjustment.SubjectsAdult patients at seven primary care clinics within a large, integrated health system in Southern California.Main MeasuresSurvey measures of experience with, acceptability of, and attitudes toward clinical social determinants of health screening and navigation.Key ResultsA total of 1161 patients participated, representing a 79% response rate. Most respondents (69%) agreed that social needs impact health and agreed their health system should ask about social needs (85%) and help address social needs (88%). Patients with social needs in the last year were more likely to (1) agree social needs impact health (OR 10.2, p < 0.001), (2) support their health system asking patients about social needs (OR 3.7, p < 0.001), and (3) support addressing patient social needs (OR 3.5, p < 0.001). Differences by social need history, gender, age, race, ethnicity, and education were found.ConclusionsMost patients at a large integrated health system supported clinical social needs screening and intervention. Differences in attitudes by social need history, gender, age, race, ethnicity, and education may indicate opportunities to develop more equitable, patient-centered approaches to addressing social needs.

Tiny habitats of tiny species: the importance of micro-refugia for threatened island-endemic arthropods
2025
Island-endemic arthropods are understudied species and likely to be highly threatened with extinction. Analysis of IUCN Red List assessments can be used to highlight important microhabitats requiring conservation for the effective management of island-endemic arthropod biodiversity. We synthesized information on the 296 island-endemic arthropod species assessed as Critically Endangered as of April 2024, the geography of the islands to which they are endemic, and the broad threats they face. These species comprised 33 taxonomic orders, across which an average of 53% of species were limited entirely to tiny, confined areas of habitat: caves, high elevation areas, isolated pools or sea stacks. These micro-refugia are most utilized by crustaceans and least utilized by myriapods. Caves and pools are the most important habitats on temperate islands where habitat degradation threatens crustaceans. On small tropical islands where arachnids and hexapods are threatened by invasive species, refugia are mostly in high elevation areas. Sea stacks appear to be effective refugia from invasive species only for threatened island-endemics with notable long-distance dispersal adaptation. None of the refugia appear effective in sustaining arthropod species immediately threatened by climate change. Using the interaction between arthropod life history, habitat and threats, it is possible to generalize micro-refugia that (1) should be immediately targeted for management, and (2) could yield undescribed or presumed-extinct species. Prioritizing such refugia for management and research can guide efficient expenditure of local capacity. In our case study, on Ascension Island, micro-refugia for seven endemic arthropods covered < 0.1% of the island's total area.

Healthcare Utilization Among Patients Diagnosed with COVID-19 in a Large Integrated Health System
2022
BackgroundThe demands for healthcare resources following a COVID-19 diagnosis are substantial, but not currently quantified.ObjectiveTo describe trends in healthcare utilization within 180 days for patients diagnosed with COVID-19 and identify patient factors associated with increased healthcare use.DesignObservational cohort study.PatientsA total of 64,011 patients with a test-confirmed COVID-19 diagnosis from March to September 2020 in a large integrated healthcare system in Southern California.Main MeasuresOverall healthcare utilization during the 180 days following COVID-19 diagnosis, as well as encounter types and reasons for visits during the first 30 days. Poisson regression was used to identify patient factors associated with higher utilization. Analyses were performed separately for patients who were and were not hospitalized for COVID-19.Key ResultsHealthcare utilization was about twice as high for hospitalized patients compared to non-hospitalized patients in all time periods. The average number of visits was highest in the first 30 days (hospitalized: 12.3 visits/30 person-days; non-hospitalized: 6.6) and gradually decreased over time. In the first 30 days, the majority of healthcare visits were telehealth encounters (hospitalized: 9.0 visits; non-hospitalized: 5.6 visits), and the most prevalent reasons for visits were COVID-related diagnoses, COVID-related symptoms, and respiratory-related conditions. For hospitalized patients, older age (≥65: RR 1.27, 95% CI 1.15–1.41), female gender (RR 1.07, 95% CI 1.05–1.09), and higher BMI (≥40: RR 1.07, 95% CI 1.03–1.10) were associated with higher total utilization. For non-hospitalized patients, older age, female gender, higher BMI, non-white race/ethnicity, former smoking, and greater number of pre-existing comorbidities were all associated with increased utilization.ConclusionsPatients with COVID-19 seek healthcare frequently within 30 days of diagnosis, placing high demands on health systems. Identifying ways to support patients diagnosed with COVID-19 while adequately providing the usual recommended care to our communities will be important as we recover from the pandemic.

Invertebrates are dominant species in primary tropical rainforests, where their abundance and diversity contributes to the functioning and resilience of these globally important ecosystems. However, more than one-third of tropical forests have been logged, with dramatic impacts on rainforest biodiversity that may disrupt key ecosystem processes. We find that the contribution of invertebrates to three ecosystem processes operating at three trophic levels (litter decomposition, seed predation and removal, and invertebrate predation) is reduced by up to one-half following logging. These changes are associated with decreased abundance of key functional groups of termites, ants, beetles and earthworms, and an increase in the abundance of small mammals, amphibians and insectivorous birds in logged relative to primary forest. Our results suggest that ecosystem processes themselves have considerable resilience to logging, but the consistent decline of invertebrate functional importance is indicative of a human-induced shift in how these ecological processes operate in tropical rainforests.
Invertebrates are key components in the ecological functioning of tropical forests. Here, Ewers
et al
. show that, compared to primary forest, logging halves the contribution of invertebrate species to several key ecosystem processes, including litter decomposition.

Embedded Research in the Learning Healthcare System: Ongoing Challenges and Recommendations for Researchers, Clinicians, and Health System Leaders
2020
Embedded research is an innovative means to improve performance in the learning healthcare system (LHS). However, few descriptions of successful embedded research programs have been published. In this perspective, we describe the Care Improvement Research Team, a mature partnership between researchers and clinicians at Kaiser Permanente Southern California. The program supports a core team of researchers and staff with dedicated resources to partner with health system leaders and practicing clinicians, using diverse methods to identify and rectify gaps in clinical practice. For example, recent projects helped clinicians to provide better care by reducing prescribing of unnecessary antibiotics for acute sinusitis and by preventing readmissions among the elderly. Embedded in operational workgroups, the team helps formulate research questions and enhances the rigor and relevance of data collection and analysis. A recent business-case analysis cited savings to the organization of over $10 million. We conclude that embedded research programs can play a key role in fulfilling the promise of the LHS. Program success depends on dedicated funding, robust data systems, and strong relationships between researchers and clinical stakeholders. Embedded researchers must be responsive to health system priorities and timelines, while clinicians should embrace researchers as partners in problem solving.

Background
Health systems are increasingly attempting to intervene on social adversity as a strategy to improve health care outcomes. To inform health system efforts to screen for social adversity, we sought to explore the stability of social risk and interest in assistance over time and to evaluate whether the social risk was associated with subsequent healthcare utilization.
Methods
We surveyed Kaiser Permanente members receiving subsidies from the healthcare exchange in Southern California to assess their social risk and desire for assistance using the Accountable Health Communities instrument. A subset of initial respondents was randomized to be re-surveyed at either three or six months later.
Results
A total of 228 participants completed the survey at both time points. Social risks were moderate to strongly stable across three and six months (Kappa range = .59-.89); however, social adversity profiles that included participants’ desire for assistance were more labile (3-month Kappa = .52; 95% CI = .41-.64 & 6-month Kappa = .48; 95% CI = .36-.6). Only housing-related social risks were associated with an increase in acute care (emergency, urgent care) six months after initial screening; no other associations between social risk and utilization were observed.
Conclusions
This study suggests that screening for social risk may be appropriate at intervals of six months, or perhaps longer, but that assessing desire for assistance may need to occur more frequently. Housing risks were associated with increases in acute care. Health systems may need to engage in screening and referral to resources to improve overall care and ultimately patient total health.

Identifying patients with symptoms suspicious for COVID-19 at elevated risk of adverse events: The COVAS score
2021
Develop and validate a risk score using variables available during an Emergency Department (ED) encounter to predict adverse events among patients with suspected COVID-19.
A retrospective cohort study of adult visits for suspected COVID-19 between March 1 – April 30, 2020 at 15 EDs in Southern California. The primary outcomes were death or respiratory decompensation within 7-days. We used least absolute shrinkage and selection operator (LASSO) models and logistic regression to derive a risk score. We report metrics for derivation and validation cohorts, and subgroups with pneumonia or COVID-19 diagnoses.
26,600 ED encounters were included and 1079 experienced an adverse event. Five categories (comorbidities, obesity/BMI ≥ 40, vital signs, age and sex) were included in the final score. The area under the curve (AUC) in the derivation cohort was 0.891 (95% CI, 0.880–0.901); similar performance was observed in the validation cohort (AUC = 0.895, 95% CI, 0.874–0.916). Sensitivity ranging from 100% (Score 0) to 41.7% (Score of ≥15) and specificity from 13.9% (score 0) to 96.8% (score ≥ 15). In the subgroups with pneumonia (n = 3252) the AUCs were 0.780 (derivation, 95% CI 0.759–0.801) and 0.832 (validation, 95% CI 0.794–0.870), while for COVID-19 diagnoses (n = 2059) the AUCs were 0.867 (95% CI 0.843–0.892) and 0.837 (95% CI 0.774–0.899) respectively.
Physicians evaluating ED patients with pneumonia, COVID-19, or symptoms suspicious for COVID-19 can apply the COVAS score to assist with decisions to hospitalize or discharge patients during the SARS CoV-2 pandemic.

BCL2 expression is enriched in advanced prostate cancer with features of lineage plasticity
2024
The widespread use of potent androgen receptor signaling inhibitors (ARSIs) has led to an increasing emergence of AR-independent castration-resistant prostate cancer (CRPC), typically driven by loss of AR expression, lineage plasticity, and transformation to prostate cancers (PCs) that exhibit phenotypes of neuroendocrine or basal-like cells. The anti-apoptotic protein BCL2 is upregulated in neuroendocrine cancers and may be a therapeutic target for this aggressive PC disease subset. There is an unmet clinical need, therefore, to clinically characterize BCL2 expression in metastatic CRPC (mCRPC), determine its association with AR expression, uncover its mechanisms of regulation, and evaluate BCL2 as a therapeutic target and/or biomarker with clinical utility. Here, using multiple PC biopsy cohorts and models, we demonstrate that BCL2 expression is enriched in AR-negative mCRPC, associating with shorter overall survival and resistance to ARSIs. Moreover, high BCL2 expression associates with lineage plasticity features and neuroendocrine marker positivity. We provide evidence that BCL2 expression is regulated by DNA methylation, associated with epithelial-mesenchymal transition, and increased by the neuronal transcription factor ASCL1. Finally, BCL2 inhibition had antitumor activity in some, but not all, BCL2-positive PC models, highlighting the need for combination strategies to enhance tumor cell apoptosis and enrich response.

Benign Paroxysmal Positional Vertigo - therapy
2025
Background
The evaluation and management of acute vertigo presentations is challenging for both patients and physicians. Benign paroxysmal positional vertigo (BPPV), acute unilateral vestibulopathy (e.g., vestibular neuritis), and stroke are priority diagnostic considerations in this circumstance. Existing evidence can be used to guide the diagnosis and treatment, however high value care opportunities—such as the Dix-Hallpike test (DHT), canalith repositioning maneuver (CRM), and gaze stabilization exercises (GSE)—are often underused, while neuroimaging studies are often overused.
Methods
This trial contains a health system focused stepped wedge intervention and an embedded individually patient randomized clinical trial. The study will start with a 6-month pre-intervention period. This will be followed by staggered intervention at the engaged EDs in 11 waves and then an approximately 6-month post-intervention period. Concurrently, patients will be recruited before and after the physician level intervention is implemented at each ED. Enrolled participants will complete baseline survey and then be randomized individually, stratified by sex, age, and medical center, to the intervention or control arm patient materials using central computerized randomization. The intervention arm will be sent intervention materials and the control arm will be sent the hospital’s standard post-discharge materials. The primary outcome of the physician-based part of the trial is use of evidence-based care practices during the index ED visit. The primary outcome of the patient focused part of the trial is the dizziness handicap index over 4 weeks.
Discussion
The DIZZTINCT-2 trial addresses key areas of uncertainty in how to improve the care of emergency department patients with acute vertigo. In addition, follow up data on how much and how fast patients improved was needed. DIZZTINCT-2 will address these key knowledge gaps efficiently.
