Lessons From Mass-Testing for Coronavirus Disease 2019 in Long-Term Care Facilities for the Elderly in San Francisco.

Coronavirus disease 2019 can cause significant mortality in the elderly in long-term care facilities (LTCF). We describe 4 LTCF outbreaks where mass testing identified a high proportion of asymptomatic infections (4%-41% in healthcare workers and 20%-75% in residents), indicating that symptom-based screening alone is insufficient for monitoring for COVID-19 transmission.

A Telemedicine Approach to Increase Treatment of Alcohol Use Disorder in Primary Care: A Pilot Feasibility Study.

BACKGROUND AND AIMS: Unhealthy drinking is a leading threat to health, yet few people with alcohol use disorder (AUD) receive treatment. This pilot tested the feasibility of addiction medicine video consultations in primary care for improving AUD medication adoption and specialty treatment initiation. METHODS: Primary care providers (PCPs) received training and access to on-call addiction medicine consultations. Feasibility measures were training attendance, intention to use the service and/or AUD pharmacotherapy, and user feedback. Secondary outcomes were utilization, prescription and treatment initiation rates, and case reports. χ2 tests were used to compare prescription and treatment initiation rates for consult recipients and non-recipients. RESULTS: Ninety-one PCPs (71.1%) attended a training, and 60 (65.9%) provided feedback. Of those, 37 (64.9%) mentioned pharmacotherapy and 41 (71.9%) intended to use the video consult service. Of 27 users, 19 provided feedback; 12 (63.1%) rated its value at 8 or above, on a scale of 1 to 10 (average 6.9). The most useful aspect was immediacy, and users wanted an easier workflow and increased consultant availability. Of 32 patients who received a consult, 11 (34.4%) were prescribed naltrexone, versus 43 (6.4%) of non-recipients (P < 0.0001); 11 (34.4%) initiated specialty treatment, versus 105 (19.7%) of non-recipients (P < 0.05). CONCLUSIONS: PCP training attendance and feedback suggest that an addiction telemedicine consult service would be valuable to PCPs and might increase AUD medication uptake and specialty addiction treatment initiation. However, future research should include significant modifications to the piloted telemedicine model: robust staffing and simpler, more flexible methods for PCPs to obtain consults.

Timely intervention and control of a novel coronavirus (COVID-19) outbreak at a large skilled nursing facility-San Francisco, California, 2020.

OBJECTIVE: To describe epidemiologic and genomic characteristics of a severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) outbreak in a large skilled-nursing facility (SNF), and the strategies that controlled transmission. DESIGN, SETTING, AND PARTICIPANTS: This cohort study was conducted during March 22-May 4, 2020, among all staff and residents at a 780-bed SNF in San Francisco, California. METHODS: Contact tracing and symptom screening guided targeted testing of staff and residents; respiratory specimens were also collected through serial point prevalence surveys (PPSs) in units with confirmed cases. Cases were confirmed by real-time reverse transcription-polymerase chain reaction testing for SARS-CoV-2, and whole-genome sequencing (WGS) was used to characterize viral isolate lineages and relatedness. Infection prevention and control (IPC) interventions included restricting from work any staff who had close contact with a confirmed case; restricting movement between units; implementing surgical face masking facility-wide; and the use of recommended PPE (ie, isolation gown, gloves, N95 respirator and eye protection) for clinical interactions in units with confirmed cases. RESULTS: Of 725 staff and residents tested through targeted testing and serial PPSs, 21 (3%) were SARS-CoV-2 positive: 16 (76%) staff and 5 (24%) residents. Fifteen cases (71%) were linked to a single unit. Targeted testing identified 17 cases (81%), and PPSs identified 4 cases (19%). Most cases (71%) were identified before IPC interventions could be implemented. WGS was performed on SARS-CoV-2 isolates from 4 staff and 4 residents: 5 were of Santa Clara County lineage and the 3 others were distinct lineages. CONCLUSIONS: Early implementation of targeted testing, serial PPSs, and multimodal IPC interventions limited SARS-CoV-2 transmission within the SNF.

Population-scale longitudinal mapping of COVID-19 symptoms, behaviour and testing.

Despite the widespread implementation of public health measures, coronavirus disease 2019 (COVID-19) continues to spread in the United States. To facilitate an agile response to the pandemic, we developed How We Feel, a web and mobile application that collects longitudinal self-reported survey responses on health, behaviour and demographics. Here, we report results from over 500,000 users in the United States from 2 April 2020 to 12 May 2020. We show that self-reported surveys can be used to build predictive models to identify likely COVID-19-positive individuals. We find evidence among our users for asymptomatic or presymptomatic presentation; show a variety of exposure, occupational and demographic risk factors for COVID-19 beyond symptoms; reveal factors for which users have been SARS-CoV-2 PCR tested; and highlight the temporal dynamics of symptoms and self-isolation behaviour. These results highlight the utility of collecting a diverse set of symptomatic, demographic, exposure and behavioural self-reported data to fight the COVID-19 pandemic.

Population-scale Longitudinal Mapping of COVID-19 Symptoms, Behavior, and Testing Identifies Contributors to Continued Disease Spread in the United States.

Despite social distancing and shelter-in-place policies, COVID-19 continues to spread in the United States. A lack of timely information about factors influencing COVID-19 spread and testing has hampered agile responses to the pandemic. We developed How We Feel, an extensible web and mobile application that aggregates self-reported survey responses, to fill gaps in the collection of COVID-19-related data. How We Feel collects longitudinal and geographically localized information on users' health, behavior, and demographics. Here we report results from over 500,000 users in the United States from April 2, 2020 to May 12, 2020. We show that self- reported surveys can be used to build predictive models of COVID-19 test results, which may aid in identification of likely COVID-19 positive individuals. We find evidence among our users for asymptomatic or presymptomatic presentation, as well as for household and community exposure, occupation, and demographics being strong risk factors for COVID-19. We further reveal factors for which users have been SARS-CoV-2 PCR tested, as well as the temporal dynamics of self- reported symptoms and self-isolation behavior in positive and negative users. These results highlight the utility of collecting a diverse set of symptomatic, demographic, and behavioral self- reported data to fight the COVID-19 pandemic.

Knowing How to Ask Good Questions: Comparing Latinos and Non-Latino Whites Enrolled in a Cardiovascular Disease Prevention Study.

INTRODUCTION: Latinos face unique challenges engaging with their health care providers for risk management of cardiovascular disease (CVD). OBJECTIVE: To better understand differences in how Latinos and non-Latino whites (NLWs) experience CVD care. METHODS: We examined self-reported activation, engagement, confidence, and communication comparing Latinos (n = 194) and NLWs (n = 208). Data were taken from baseline survey assessments of participants in the CREATE Wellness Study (NCT02302612), designed to help patients with poorly controlled CVD risk factors more actively engage in their care. The groups were compared using χ2 tests and separate logistic regression models adjusting for age, age and income, and age and educational attainment. RESULTS: Latinos in this cohort were younger, were less educated, and had lower incomes than did NLWs. In age-adjusted models, Latinos were significantly less likely to report knowing how to ask good questions about their health (71.1% vs 83.7% for NLW, p < 0.01; adjusted odds ratio = 0.49, 95% confidence interval = 0.29-0.83). Further adjustment by educational attainment or income did not attenuate this association. Latinos were also significantly more likely to report positive experiences and confidence with several measures of chronic illness care (adjusted odds ratio range = 1.57-2.01). Further adjustment by educational attainment eliminated these associations. CONCLUSION: We found notable differences between Latinos and NLWs in their experience of health care. These results provide insights into how CVD risk management programs can be tailored for Latinos. Interventions to improve patient activation and engagement for Latinos with CVD should emphasize question-asking skills.

CREATE Wellness: A multi-component behavioral intervention for patients not responding to traditional Cardiovascular disease management.

BACKGROUND/AIMS: Cardiovascular disease (CVD) is the leading cause of death in the US. Many patients do not benefit from traditional disease management approaches to CVD risk reduction. Here we describe the rationale, development, and implementation of a multi-component behavioral intervention targeting patients who have persistently not met goals of CVD risk factor control. METHODS: Informed by published evidence, relevant theoretical frameworks, stakeholder advice, and patient input, we developed a group-based intervention (Changing Results: Engage and Activate to Enhance Wellness; "CREATE Wellness") to address the complex needs of patients with elevated or unmeasured CVD-related risk factors. We are testing this intervention in a randomized trial among patients with persistent (i.e > 2 years) sub-optimal risk factor control despite being enrolled in an advanced and highly successful CVD disease management program. RESULTS: The CREATE Wellness intervention is designed as a 3 session, group-based intervention combining proven elements of patient activation, health system engagement skills training, shared decision making, care planning, and identification of lifestyle change barriers. Our key learnings in designing the intervention included the value of multi-level stakeholder input and the importance of pragmatic skills training to address barriers to care. CONCLUSIONS: The CREATE Wellness intervention represents an evidence-based, patient-centered approach for patients not responding to traditional disease management. The trial is currently underway at three medical facilities within Kaiser Permanente Northern California and next steps include an evaluation of efficacy, adaptation for non-English speaking patient populations, and modification of the curriculum for web- or phone-based versions.
