Enhancing community engagement, public involvement, and social capital through researchers' participation in community dance projects: unexpected outcomes in underserved communities.

BACKGROUND: The Dance and Health project aimed to promote public involvement in health research. Public involvement leads worked with project partner community groups, Aakash Odedra Dance Company and Moving Together, to develop a community engagement project with people living in low-socioeconomic areas/deprivation and diverse ethnic minority groups. Dance and Health included a weekly 60-min dance class and 30 min of facilitated health science discussion, that could either be a public involvement discussion for a research project, an activity about a particular biomedical research theme or ongoing discussions with a visiting researcher. The goal of this paper is to explore the impact of the Dance and Health project on the social capital of participants and provide key learnings on how to engage and build partnerships with people from underserved groups in health research contexts. METHODS: Qualitative interviews and focus groups were completed which explored participant and dance tutor experiences in community venues. Participants were aged between 22 and 90, most were female and were from Asian ethnic minority groups and White British groups living in deprived neighbourhoods in Leicester. Qualitative data were analysed using qualitative content analysis. RESULTS: The responses to the Dance and Health project were positive across all the focus groups. Central themes identified were Feedback on the Project, Motivation to Exercise, Criticism of the NHS, Mental Wellbeing, Engagement in a Post Pandemic New Normal, Accessibility and Inclusivity, Empowerment and Building Social Capital. DISCUSSION: The focus groups evidenced that the project had broad impact. Participants expressed empowerment and ownership and described a range of social capital enrichment generated through the project including networks and friendships, access to the institutional resource of health science, and the opportunity to engage with a health and leisure activity that was valued and meaningful.

A research team worked with community dance schools in Leicester to try to get more people from the Asian community and from poorer neighbourhoods involved in research and science. By taking part in the project, people benefitted from an opportunity to exercise and to learn about and influence health research taking place locally. However, the researchers also noticed that there were other benefits to the project. Dancing and learning about health science helped people bond and form new friendships. The researchers joined in, and this helped build friendships and trust between participants and people working in science and research. This is called bridging which is where we bring people together from different groups. The dance sessions made the researchers more approachable and less intimidating, so it was easier to trust them and build friendships. Bridging and bonding are ways of building social capital. Social capital describes the social resources that people can access in their neighbourhoods and communities e.g. facilities (village halls or clubs) and support networks. Researchers delivered focus groups in which participants talked about Feedback on the Project, Motivation to Exercise, Criticism of the NHS, Mental Wellbeing, Engagement in a Post Pandemic New Normal, Accessibility and Inclusivity, Empowerment and Social Capital. This supported the idea that projects where we try to engage with communities can build social capital. This is most likely when projects provide safety and accessibility, (1) and flexibility, a sense of belonging, commitment, communication, being genuine, relevance, sustainability (4).

Ethical considerations in public engagement: developing tools for assessing the boundaries of research and involvement.

Public engagement with research (PEwR) has become increasingly integral to research practices. This paper explores the process and outcomes of a collaborative effort to address the ethical implications of PEwR activities and develop tools to navigate them within the context of a University Medical School. The activities this paper reflects on aimed to establish boundaries between research data collection and PEwR activities, support colleagues in identifying the ethical considerations relevant to their planned activities, and build confidence and capacity among staff to conduct PEwR projects. The development process involved the creation of a taxonomy outlining key terms used in PEwR work, a self-assessment tool to evaluate the need for formal ethical review, and a code of conduct for ethical PEwR. These tools were refined through iterative discussions and feedback from stakeholders, resulting in practical guidance for researchers navigating the ethical complexities of PEwR. Additionally, reflective prompts were developed to guide researchers in planning and conducting engagement activities, addressing a crucial aspect often overlooked in formal ethical review processes. The paper reflects on the broader regulatory landscape and the limitations of existing approval and governance processes, and prompts critical reflection on the compatibility of formal approval processes with the ethos of PEwR. Overall, the paper offers insights and practical guidance for researchers and institutions grappling with ethical considerations in PEwR, contributing to the ongoing conversation surrounding responsible research practices.

Schools and Wastewater Surveillance: Practical Implications for an Emerging Technology to Impact Child Health.

Since the start of the COVID-19 pandemic, wastewater surveillance has emerged as a public health tool that supplements traditional surveillance methods used to detect the prevalence of the SARS-CoV-2 virus in communities. In May 2020, the Houston Health Department (HHD) partnered with a coalition of municipal and academic partners to develop a wastewater monitoring and reporting system for the city of Houston, Texas. The HHD subsequently launched a program to conduct targeted wastewater sampling at 52 school sites located in a large, urban school district in Houston. Data generated by this program are shared with school district officials and nurses from participating schools. Although initial feedback from these stakeholders indicated that they considered the wastewater data valuable, the emergency nature of the pandemic prevented a systematic evaluation of the program. To address this gap in knowledge, the HHD and Rice University conducted a study to determine how wastewater data are used to make decisions about COVID-19 prevention and mitigation practices in schools. Our findings indicate that maximizing the utility of wastewater data in the school context will require the development of communication strategies and education efforts tailored to the needs of specific audiences and improving collaboration between local health departments, school districts, and school nurses.

Association between early care and education centres policies and practices and children's healthy behaviours.

OBJECTIVE: To examine the impact of nutritional and physical activity (PA) policies and practices at early care and education centres on behavioural changes among children ages 2-5. METHODS: The study population included 586 children from 25 education centres throughout the state of Georgia. Policies and practices were measured using the Georgia Nutrition and PA Assessment at the start of school year in Fall 2017. Survey data were collected at the beginning of school year September/October 2017 and at the end of school year April/May 2018 to measure changes in children's nutritional and PA behaviour over the school year. We used generalised estimating equations to estimate odds ratios and 95% confidence intervals. RESULTS: Children at centres with a high nutrition assessment score had higher odds of increasing vegetable consumption (OR = 2.1; 95% CI: 1.1, 4.0) while the odds of increasing fruit (OR = 1.4; 95% CI: 0.8, 2.4) and water (OR = 1.2; 95% CI: 0.5, 2.7) consumption increased non-significantly. The odds of improving PA were similar between children at centres with a high versus a low PA assessment score. CONCLUSION: The results, though insignificant, indicate that policies and practices could influence children's health behaviours. Further research is warranted to examine whether improvements in policies and practices could explain changes in children's health behaviours, the impact of educator's knowledge on children's health behaviours and the implementation of and adherence to policy and practice improvement plans.

Nutritional compensation of the circadian clock is a conserved process influenced by gene expression regulation and mRNA stability.

Compensation is a defining principle of a true circadian clock, where its approximately 24-hour period length is relatively unchanged across environmental conditions. Known compensation effectors directly regulate core clock factors to buffer the oscillator's period length from variables in the environment. Temperature Compensation mechanisms have been experimentally addressed across circadian model systems, but much less is known about the related process of Nutritional Compensation, where circadian period length is maintained across physiologically relevant nutrient levels. Using the filamentous fungus Neurospora crassa, we performed a genetic screen under glucose and amino acid starvation conditions to identify new regulators of Nutritional Compensation. Our screen uncovered 16 novel mutants, and together with 4 mutants characterized in prior work, a model emerges where Nutritional Compensation of the fungal clock is achieved at the levels of transcription, chromatin regulation, and mRNA stability. However, eukaryotic circadian Nutritional Compensation is completely unstudied outside of Neurospora. To test for conservation in cultured human cells, we selected top hits from our fungal genetic screen, performed siRNA knockdown experiments of the mammalian orthologs, and characterized the cell lines with respect to compensation. We find that the wild-type mammalian clock is also compensated across a large range of external glucose concentrations, as observed in Neurospora, and that knocking down the mammalian orthologs of the Neurospora compensation-associated genes CPSF6 or SETD2 in human cells also results in nutrient-dependent period length changes. We conclude that, like Temperature Compensation, Nutritional Compensation is a conserved circadian process in fungal and mammalian clocks and that it may share common molecular determinants.

Telehealth Support for Dementia Caregivers During the COVID-19 Pandemic: Lessons Learned From the NYU Family Support Program.

OBJECTIVES: In response to the needs of dementia caregivers during the COVID-19 pandemic, the NYU Langone Alzheimer's Disease and Related Disorders Family Support Program (FSP) quickly transitioned to providing most services online. To understand how dementia caregivers experienced FSP services after the switch to video telehealth, we conducted qualitative interviews of spouse or partner dementia caregivers. PARTICIPANTS: Ten participants were recruited from a convenience sample of dementia spouse or partner caregivers who used one or more online FSP services offered during the pandemic. DESIGN: Caregivers engaged in semi-structured interviews held via videoconference between May and June 2020. Qualitative analysis of interviews was conducted according to the principles of framework analysis. RESULTS: Caregivers reported high satisfaction with the FSP pre-pandemic and continued to feel supported when services were provided online. They transitioned to video telehealth services with little difficulty. CONCLUSIONS: While video telehealth is frequently cited as beneficial for those in rural communities, socioeconomically disadvantaged groups, or homebound individuals, our findings suggest that video telehealth is also advantageous for dementia caregivers, given their unique barriers, including lack of time due to caregiving responsibilities, lack of respite care for the person with dementia, and the additional burdens of travel time to access in-person services.

Functional analysis of 110 phosphorylation sites on the circadian clock protein FRQ identifies clusters determining period length and temperature compensation.

In the negative feedback loop driving the Neurospora circadian oscillator, the negative element, FREQUENCY (FRQ), inhibits its own expression by promoting phosphorylation of its heterodimeric transcriptional activators, White Collar-1 (WC-1) and WC-2. FRQ itself also undergoes extensive time-of-day-specific phosphorylation with over 100 phosphosites previously documented. Although disrupting individual or certain clusters of phosphorylation sites has been shown to alter circadian period lengths to some extent, it is still elusive how all the phosphorylations on FRQ control its activity. In this study, we systematically investigated the role in period determination of all 110 reported FRQ phosphorylation sites, using mutagenesis and luciferase reporter assays. Surprisingly, robust FRQ phosphorylation is still detected even when 84 phosphosites were eliminated altogether; further mutating another 26 phosphoresidues completely abolished FRQ phosphorylation. To identify phosphoresidue(s) on FRQ impacting circadian period length, a series of clustered frq phosphomutants covering all the 110 phosphosites were generated and examined for period changes. When phosphosites in the N-terminal and middle regions of FRQ were eliminated, longer periods were typically seen while removal of phosphorylation in the C-terminal tail resulted in extremely short periods, among the shortest reported. Interestingly, abolishing the 11 phosphosites in the C-terminal tail of FRQ not only results in an extremely short period, but also impacts temperature compensation (TC), yielding an overcompensated circadian oscillator. In addition, the few phosphosites in the middle of FRQ are also found to be crucial for TC. When different groups of FRQ phosphomutations were combined intramolecularly, expected additive effects were generally observed except for one novel case of intramolecular epistasis, where arrhythmicity resulting from one cluster of phosphorylation site mutants was restored by eliminating phosphorylation at another group of sites.

Medical students' experience of studying while working part-time and the effects of COVID-19.

AIMS: The costs of being a medical student are large and increasing, and many students need to work part-time to meet financial pressures. This study explores the impact that part-time extracurricular paid work during the academic year has on medical student wellbeing, their interactions with the curriculum, and the effect of COVID-19 on work in 2020. METHODS: An online survey in 2020 gathered demographic, quantitative and qualitative information from medical students and their work experiences. Descriptive statistics analysed quantitative data; qualitative data were analysed using qualitative content analysis. RESULTS: Of the 36% (n=530) of students who responded, 255 (49%) reported undertaking paid part-time work, with 59 (24%) reporting they would not be able to remain studying if they did not work. When interacting with the medical programme, 43% of students reported their work conflicted with scheduled medical school commitments, and 70% reported conflicts between work and individual study. COVID-19 disrupted 57% of paid work during the year. Impacts on students' wellbeing were both positive and negative. Positive aspects included developing new skills, self-confidence and resilience. Working also provided an escape from the study demands of the medical programme. Negative aspects were predominantly about the increased stress working had on students, specifically on the impact of paid work on their own health. CONCLUSIONS: Almost half of medical students work part-time while studying. Understanding the perceived implications that part-time work has on student education and wellbeing could help medical schools provide appropriate advice and pastoral support for their students.

White-Nose Syndrome Pathogen Pseudogymnoascus destructans Detected in Migratory Tree-Roosting Bats.

White-nose syndrome (WNS) is an emerging fungal epizootic disease that has caused large-scale mortality in several species of North American bats. The fungus that causes WNS, Pseudogymnoascus destructans (Pd), has also been detected in bat species without diagnostic signs of WNS. Although these species could play a role in WNS spread, understanding of the spatial and temporal extents of Pd occurrence on WNS-resistant species is limited. This study evaluated the presence of Pd on 272 individuals of three species of migratory tree-roosting bats: hoary (Lasiurus cinereus), eastern red (Lasiurus borealis), and silver-haired (Lasionycteris noctivagans) bats, obtained opportunistically during summer and autumn from throughout much of their ranges in North America. We also compared tissue sampling protocols (i.e., tissue swabbing, fur swabbing, and DNA extraction of excised wing tissue). We detected Pd on three eastern red bats from Illinois and Ohio, US, one silver-haired bat from West Virginia, US, and one hoary bat from New York, US, all via DNA extracted from wing tissue of carcasses. These results document the first publicly reported detections of Pd on a hoary bat and on migratory bats during the autumn migratory period, and demonstrate the potential for using carcasses salvaged at wind-energy facilities to monitor for Pd.

Longitudinal study: understanding the lived experience of couples across the trajectory of dementia.

BACKGROUND: The longitudinal study, "Couples Lived Experiences," focuses on whether and how relationship characteristics of older couples change with the cognitive decline of one member of the couple, and how these changes affect each individual's emotional and physical health outcomes. Until now, most psychosocial research in dementia has focused either on the person with dementia (PWD) or the caregiver separately. The previous literature examining relationship characteristics and their role in outcomes for the caregiver and PWD is scant and suffers from methodological issues that limit the understanding of which relationship characteristics most influence outcomes for caregivers and care-receivers and what other factors may mitigate or exacerbate their effects. METHODS: We will enroll 300 dyads and collect information via online interviews of each member of the couple, every 6 months for 3 years. Relationship characteristics will be measured with a set of short, well-validated, and reliable self-report measures, plus the newly developed "Partnership Approach Questionnaire." Outcomes include global quality of life, subjective physical health, mental health (depression and anxiety), and status change (transitions in levels of care; i.e., placement in a nursing home). Longitudinal data will be used to investigate how relationship characteristics are affected by cognitive, functional, and behavioral changes, and the impact of these changes on health outcomes. Qualitative data will also be collected to enrich the interpretation of results of quantitative analyses. DISCUSSION: Psychosocial interventions have demonstrated effectiveness in promoting the wellbeing of PWD and their caregivers. The knowledge gained from this study can lead to the development or enhancement of targeted interventions for older couples that consider the impact of cognitive and functional decline on the relationship between members of a couple and thereby improve their wellbeing. TRIAL REGISTRATION: This study has been registered with ClinicalTrials.gov. ClinicalTrials.gov Identifier is: NCT04863495 .

Effect of Palliative Care Curriculum on Serious Illness Conversation Preparedness.

BACKGROUND: A shortage of palliative pare (PC) specialists underscores the necessity that all clinicians feel comfortable with serious illness conversations (SICs). OBJECTIVE: To assess the effect of an intensive PC curriculum with multiple teaching modalities on Internal Medicine residents' confidence with SICs and advance care planning documentation. METHODS: Twelve PC modules consisting of didactic lectures, role-playing, and online interactive modules were integrated as continuing education during academic year 2018-2019. Surveys were administered precurriculum and at 3 and 6 months postcurriculum to measure the primary outcome of increasing resident preparedness for SICs. A retrospective chart review was used to analyze secondary outcomes of advance care planning documentation for patients cared for by residents exposed to the curriculum versus residents from the previous year who received monthly didactic PC lectures. RESULTS: Postintervention surveys demonstrated statistically significant improvement in resident confidence. An increase in patient code status confirmation rates (odds ratio, 1.81; 95% confidence interval, 1.12-2.94; P = 0.02) and a decrease in PC consultation (odds ratio, 0.56; 95% confidence interval, 0.33-0.97; P = 0.04) was observed when compared with the previous year. CONCLUSION: Among residents, the incorporation of an intensive PC curriculum that uses multiple teaching modalities improves confidence in SICs, which we believe is integral to the practice of goal-concordant patient care.

Obesity and the Risk of Intubation or Death in Patients With Coronavirus Disease 2019.

OBJECTIVES: To characterize the impact of obesity on disease severity in patients with coronavirus disease 2019. DESIGN: This was a retrospective cohort study designed to evaluate the association between body mass index and risk of severe disease in patients with coronavirus disease 2019. Data were abstracted from the electronic health record. The primary endpoint was a composite of intubation or death. SETTING: Two hospitals in Massachusetts (one quaternary referral center and one affiliated community hospital). PATIENTS: Consecutive patients hospitalized with confirmed coronavirus disease 2019 admitted between March 13, 2020, and April 3, 2020. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: A total of 305 patients were included in this study. We stratified patients by body mass index category: < 25 kg/m (54 patients, 18%), ≥ 25 kg/m to < 30 kg/m (124 patients, 41%), ≥ 30 kg/m to < 35 kg/m (58 patients, 19%), and ≥ 35 kg/m (69 patients, 23%). In total, 128 patients (42%) had a primary endpoint (119 patients [39%] were intubated and nine died [3%] without intubation). Sixty-five patients (51%) with body mass index greater than or equal to 30 kg/m were intubated or died. Adjusted Cox models demonstrated that body mass index greater than or equal to 30 kg/m was associated with a 2.3-fold increased risk of intubation or death (95% CI, 1.2-4.3) compared with individuals with body mass index less than 25 kg/m. Diabetes was also independently associated with risk of intubation or death (hazard ratio, 1.8; 95% CI, 1.2-2.7). Fifty-six out of 127 patients (44%) with body mass index greater than or equal to 30 kg/m had diabetes, and the combination of both diabetes and body mass index greater than or equal to 30 kg/m was associated with a 4.5-fold increased risk of intubation or death (95% CI, 2.0-10.2) compared with patients without diabetes and body mass index less than 25 kg/m. CONCLUSIONS: Among consecutive patients hospitalized with coronavirus disease 2019, obesity was an independent risk factor for intubation or death.

The effect of patient code status on surgical resident decision making: A national survey of general surgery residents.

BACKGROUND: Multiple studies have demonstrated that, compared with their full code counterparts, patients with do-not-resuscitate or do-not-intubate status have higher in-hospital and postdischarge mortality than predicted by clinical characteristics alone. We sought to determine whether patient code status affects surgical resident decision making. METHODS: We created an online survey that consisted of 4 vignettes, followed by 10 questions regarding decisions on possible diagnostic and therapeutic interventions. All program directors of Accreditation Council for Graduate Medical Education-accredited general surgery residencies were randomized to receive 1 of 2 survey versions that differed only in the code status of the patients described, with requests to distribute the survey to their residents. Responses to each question were based on a Likert scale. RESULTS: A total of 194 residents completed the survey, 51% of whom were women, and all years of surgical residency were represented. In all vignettes, patient code status influenced perioperative medical decisions, ranging from initiation of dialysis to intensive care unit transfer. In 2 vignettes, it affected decisions to proceed with indicated emergency operations. CONCLUSION: When presented with patient scenarios pertaining to clinical decision making, surgical residents tend to assume that patients with a do-not-resuscitate or do-not-intubate code status would prefer to receive less aggressive care overall. As a result, the delivery of appropriate surgical care may be improperly limited unless a patient's goals of care are explicitly stated. It is important for surgical residents to understand that a do-not-resuscitate or do-not-intubate code status should not be interpreted as a "do-not-treat" status.

Association Between Do Not Resuscitate/Do Not Intubate Orders and Emergency Medicine Residents' Decision Making.

BACKGROUND: Research has shown that do not resuscitate (DNR) and do not intubate (DNI) orders may be construed by physicians to be more restrictive than intended by patients. Previous studies of physicians found that DNR/DNI orders are associated with being less willing to provide invasive care. OBJECTIVES: The purpose of this study was to assess the influence of code status on emergency residents' decision-making regarding offering invasive procedures for those patients with DNR/DNI compared with their full code counterparts. METHODS: We conducted a nationwide survey of emergency medicine residents using an instrument of 4 clinical vignettes involving patients with serious illnesses. Two versions of the survey, survey A and survey B, alternated the DNR/DNI and full code status for the vignettes. Residency leaders were contacted in August 2018 to distribute the survey to their residents. RESULTS: Three hundred and three residents responded from across the country. The code status was strongly associated with decisions to intubate or perform CPR and influenced the willingness to offer other invasive procedures. DNR/DNI status was associated with less frequent willingness to place central venous catheters (88.2% for DNR/DNI vs. 97.2% for full code, p < 0.001), admit patients to the intensive care unit (89.9% vs. 99.0%, p < 0.001), offer dialysis (79.3% vs. 98.0%, p < 0.001), and surgical consultation (78.7% vs. 94.2%, p < 0.001). CONCLUSIONS: In a nationwide survey, emergency medicine residents were less willing to provide invasive procedures for patients with DNR/DNI status, including the placement of central venous catheters, admission to the intensive care unit, and consultation for dialysis and surgery.

Equipoise in Appropriate Initial Volume Resuscitation for Patients in Septic Shock With Heart Failure: Results of a Multicenter Clinician Survey.

PURPOSE: International clinical practice guidelines call for initial volume resuscitation of at least 30 mL/kg body weight for patients with sepsis-induced hypotension or shock. Although not considered in the guidelines, preexisting cardiac dysfunction may be an important factor clinicians weigh in deciding the quantity of volume resuscitation for patients with septic shock. METHODS: We conducted a multicenter survey of clinicians who routinely treat patients with sepsis to evaluate their beliefs, behaviors, knowledge, and perceived structural barriers regarding initial volume resuscitation for patients with sepsis and concomitant heart failure with reduced ejection fraction (HFrEF) <40%. Initial volume resuscitation preferences were captured as ordinal values, and additional testing for volume resuscitation preferences was performed using McNemar and Wilcoxon signed rank tests as indicated. Univariable logistic regression models were used to identify significant predictors of ≥30 mL/kg fluid administration. RESULTS: A total of 317 clinicians at 9 US hospitals completed the survey (response rate 47.3%). Most respondents were specialists in either internal medicine or emergency medicine. Substantial heterogeneity was found regarding sepsis resuscitation preferences for patients with concomitant HFrEF. The belief that patients with septic shock and HFrEF should be exempt from current sepsis bundle initiatives was shared by 39.4% of respondents. A minimum fluid challenge of ∼30 mL/kg or more was deemed appropriate in septic shock by only 56.4% of respondents for patients with concomitant HFrEF, compared to 89.1% of respondents for patients without HFrEF (P < .01). Emergency medicine physicians were most likely to feel that <30 mL/kg was most appropriate in patients with septic shock and HFrEF. CONCLUSIONS: Clinical equipoise exists regarding initial volume resuscitation for patients with sepsis-induced hypotension or shock and concomitant HFrEF. Future studies and clinical practice guidelines should explicitly address resuscitation in this subpopulation.

Feasibility of a Multicomponent Program to Promote Physical Activity and Nutrition in Georgia Low-Income Early Care and Education Settings.

BACKGROUND: This article describes the process and intermediate outcomes from a program implemented in 65 Early Care and Education (ECE) centers serving low-income families throughout Georgia during the 2014-2017 school years. METHODS: The HealthMPowers' Empowering Healthy Choices in Schools, Homes, and Communities ECE program was based on the organization's previously successful elementary school program and aligns with current early childhood nutrition and physical activity recommendations. Participating centers worked with HealthMPowers for up to 3 years. A team from each center led changes by conducting annual self-assessments, creating and implementing improvement plans, and implementing nutrition and physical activity programs using educational resources and environmental cues. A monitoring and evaluation plan provided ongoing feedback to HealthMPowers and centers. Family and staff surveys provided insights into behaviors of children, families, and staff. Process measures included specific benchmarks (e.g., center leadership team formation, improvement plan implementation). Annual self-assessment results served as intermediate outcome measures. RESULTS: As of 2017, 65 centers had enrolled in the program. All centers formed a health team and completed the baseline self-assessment and most implemented an improvement plan (88%). At the 1-year follow-up self-assessment, centers reported improvements from baseline including never offering food incentives for good behavior (75%-86%), conducting taste testing at least once a month (61%-79%), and rarely/never serving sugar-sweetened beverages (93%-96%). CONCLUSIONS: Initial process measures from a multicomponent health promotion program in ECE were promising. An integrated continuous improvement approach to working with child care settings is feasible and likely effective.

Analyzing Who, When, and Where: Data for Better Targeting of Resources for School-Based Asthma Interventions.

BACKGROUND: Rates of uncontrolled asthma vary by demographics, space, and time. This article uses data on ambulance-treated asthma attacks in children to analyze these variations so that school districts can improve their asthma management interventions. METHODS: Incidence rates of 1826 ambulance-treated asthma attacks for children aged 5-18 years were calculated for school zones for elementary, middle, and high schools in the Houston (Texas) Independent School District (HISD). Zones with rates in the upper quartile were identified as the highest rate zones and were compared with other school zones in the district by demographics, location, and timing of attacks. RESULTS: The ambulance-treated asthma rate was respectively 5, 3, and 2 times greater in the highest rate school zones compared with all other school zones for those school levels. Ambulance-treated asthma attacks in the high-rate school zones occurred most at midday and in the evening and high-rate zones were often geographically contiguous. Schools in the high-rate zones had a higher percent of socioeconomically disadvantaged students and were more often without a school nurse. CONCLUSION: Spatial and temporal analysis of ambulance data can be valuable tools for schools to focus policy and program interventions for the students in need of improved asthma management.

Association between Do Not Resuscitate/Do Not Intubate Status and Resident Physician Decision-making. A National Survey.

RATIONALE: Compared with their Full Code counterparts, patients with do not resuscitate/do not intubate (DNR/DNI) status receive fewer interventions and have higher mortality than predicted by clinical characteristics. OBJECTIVES: To assess whether internal medicine residents, the front-line providers for many hospitalized patients, would manage hypothetical patients differently based on code status. We hypothesized respondents would be less likely to provide a variety of interventions to DNR/DNI patients than to Full Code patients. METHODS: Cross-sectional, randomized survey of U.S. internal medicine residents. We created two versions of an internet survey, each containing four clinical vignettes followed by questions regarding possible interventions; the versions were identical except for varying code status of the vignettes. Residency programs were randomly allocated between the two versions. RESULTS: Five hundred thirty-three residents responded to the survey. As determined by Chi-squared and Fisher's exact test, decisions to intubate or perform cardiopulmonary resuscitation were largely dictated by patient code status (>94% if Full Code, <5% if DNR/DNI; P < 0.0001 for all scenarios). Resident proclivity to deliver noninvasive interventions (e.g., blood cultures, medications, imaging) was uniformly high (>90%) and unaffected by code status. However, decisions to pursue other aggressive or invasive options (e.g., dialysis, bronchoscopy, surgical consultation, transfer to intensive care unit) differed significantly based on code status in most vignettes. CONCLUSIONS: Residents appear to assume that patients who would refuse cardiopulmonary resuscitation would prefer not to receive other interventions. Without explicit clarification of the patient's goals of care, potentially beneficial care may be withheld against the patient's wishes.
