Patient Characteristics Associated with Telehealth Scheduling and Completion in Primary Care at a Large, Urban Public Healthcare System.

Understanding patient characteristics associated with scheduling and completing telehealth visits can identify potential biases or latent preferences related to telehealth usage. We describe patient characteristics associated with being scheduled for and completing audio and video visits. We used data from patients at 17 adult primary care departments in a large, urban public healthcare system from August 1, 2020 to July 31, 2021. We used hierarchical multivariable logistic regression to generate adjusted odds ratios (aOR) for patient characteristics associated with having been scheduled for and completed telehealth (vs in-person) visits and for video (vs audio) scheduling and completion during two time periods: a telehealth transition period (N = 190,949) and a telehealth elective period (N = 181,808). Patient characteristics were significantly associated with scheduling and completion of telehealth visits. Many associations were similar across time periods, but others changed over time. Patients who were older (≥ 65 years old vs 18-44 years old: aOR for scheduling 0.53/completion 0.48), Black (0.86/0.71), Hispanic (0.76/0.62), or had Medicaid (0.93/0.84) were among those less likely to be scheduled for or complete video (vs audio) visits. Patients with activated patient portals (1.97/3.34) or more visits (≥ 3 scheduled visits vs 1 visit: 2.40/1.52) were more likely to be scheduled for or complete video visits. Variation in scheduling/completion explained by patient characteristics was 7.2%/7.5%, clustering by provider 37.2%/34.9%, and clustering by facility 43.1%/37.4%. Stable and dynamic associations suggest persistent gaps in access and evolving preferences/biases. Variation explained by patient characteristics was relatively low compared with that explained by provider and facility clustering.

Discovery of novel bicyclic[3.3.0]proline peptidyl α-ketoamides as potent 3CL-protease inhibitors for SARS-CoV-2.

The outbreak of SARS-CoV-2 has caused global crisis on health and economics. The multiple drug-drug interaction risk associated with ritonavir warrants specialized assessment before using Paxlovid. Here we report a multiple-round SAR study to provide a novel bicyclic[3.3.0]proline peptidyl α-ketoamide compound 4a, which is endowed with excellent antiviral activities and pharmacokinetic properties. Also, in vivo HCoV-OC43 neonatal mice model demonstrated compound 4a has good in vivo efficacy. Based on these properties, compound 4a worth further SAR optimization with the goal to develop compounds with better pharmacokinetic properties and finally to realize single agent efficacy in human.

Impact of COVID-19 on the Delivery of Eye Care to Uninsured Diabetic Patients at a Student-Run Free Clinic: A Comprehensive Evaluation of Eye Clinic Performance.

Background: Diabetic retinopathy is the leading cause of blindness among working-age adults in the United States and requires timely screening and management. This study evaluates the impact of the coronavirus disease 2019 (COVID-19) pandemic on diabetic retinopathy screening (DRS) for uninsured, predominantly Latino patients at the University of California San Diego Student-Run Free Clinic Project (SRFCP). Methods: A retrospective chart review was conducted of all living diabetic patients at SRFCP who were seen in 2019 (n=196), 2020 (n=183), and 2021 (n=178). Ophthalmology clinic referrals, scheduled patient visits, and visit outcomes were analyzed longitudinally to determine the impact of the pandemic on screening patterns. Results: The study population was 92.1% Latino, 69.5% female, with a mean age of 58.7 years. The distribution of patients seen (p<0.001), referred (p=0.012), and scheduled (p<0.001) in 2020 and 2021 significantly differed from 2019. In 2019, 50.5% of 196 patients eligible for DRS were referred, 49.5% were scheduled, and 45.4% were seen. In 2020, 41.5% of 183 eligible patients were referred, but only 20.2% were scheduled and 11.4% were seen. In 2021, there was a rebound: 63.5% of 178 patients were referred, 56.2% scheduled and 46.1% seen. No shows and cancellations represented 12.4% and 6.2% of the 97 encounters scheduled in 2019, but were markedly higher (10.8% and 40.5% respectively) for the 37 encounters scheduled in 2020. Conclusions: The COVID-19 pandemic significantly impacted the delivery of eye care at SRFCP. The need for annual DRS exceeded the capacity of the ophthalmology clinic in all years studied, but the difference was especially pronounced with more stringent COVID-19 restrictions in 2020. SRFCP patients could benefit from telemedicine DRS programs to improve screening capacity.

Incentivizing COVID-19 vaccination among racial/ethnic minority adults in the United States: $209 per dose could convince the hesitant.

BACKGROUND: More than two years into the coronavirus disease (COVID-19) pandemic, it remains unclear whether financial incentives can reduce vaccine hesitancy and improve uptake among key unvaccinated populations. This study estimated the willingness of racial/ethnic minority adults in the United States to accept financial incentives for COVID-19 vaccination and the minimum amount needed to vaccinate a sufficiently high percentage of this population. METHODS: From August through September 2021, we conducted an online survey of 367 Black/African American and Hispanic patients, age ≥ 18 years, from 8 community health centers in Rhode Island. Contingent valuation questions assessed respondents' willingness-to-accept (WTA) incentives for COVID-19 vaccination using random-starting-points and iterative incentive offers of $5 to $50 per dose. Ordered logistic regression models examined associations between respondent characteristics and WTA. Predictive probabilities were modeled using both within-survey range and out-of-survey range incentive offer amounts and compared against vaccination thresholds needed to reach herd immunity. RESULTS: Less than 30% of unvaccinated survey respondents were WTA an incentive of $50/dose for vaccination. Models using out-of-survey incentive offer amounts greater than $50 suggested that 85% of respondents would agree $140/dose (95% CI: $43-$236) could convince other people to accept vaccination, while $209/dose (95% CI: -$91-$509) would be needed for 85% of respondents to accept vaccination themselves. CONCLUSIONS: Findings from this analysis may inform the design of incentive schemes aiming to reduce racial/ethnic disparities in vaccine and booster uptake, which will continue to be important as new variants of SARS-CoV-2 emerge.

Patient satisfaction with telehealth versus in-person visits during COVID-19 at a large, public healthcare system.

RATIONALE: During the coronavirus disease pandemic, audio-only and video telehealth visits became more widely available, but the relative patient satisfaction between telehealth and in-person modalities is not well-described. AIMS AND OBJECTIVES: Our objective was to compare patient satisfaction with audio-only, video, and in-person adult primary care visits at a large, urban public healthcare system. METHODS: In this cross-sectional study, we used aggregated data from Press Ganey patient satisfaction surveys at 17 primary care facilities at New York City Health + Hospitals for visits between 1 June 2021 to 30 November 2021. We compared mean scores for questions common to surveys for each modality in domains of Access, Care Provider, and Overall Assessment using pairwise comparisons with two-tailed t-tests. RESULTS: There were 7,183/79,562 (9.0%) respondents for in-person visits and 1,009/15,092 (6.7%) respondents for telehealth visits. Compared to respondents for in-person visits, respondents for telehealth visits were more likely to be aged 35-64 years, Asian, and speak English as their primary language, and less likely to be ≥65 years old, Black or other race, and speak Spanish or another language as their primary language (p < 0.001). Patients reported higher mean satisfaction for Access measures for telehealth visits than in-person visits (p < 0.001). For Care Provider satisfaction questions, video visits generally had higher mean scores than in-person and, in turn, audio-only visits. For Overall Assessment questions, video visits had higher mean scores than in-person and, subsequently, audio-only visits. CONCLUSION: Of the visit modalities, video visits had the highest mean satisfaction scores across all domains. Telehealth may improve experiences with access, but audio-only visits may provide poorer visit experiences.

Effectiveness of controlling COVID-19 epidemic by implementing soft lockdown policy and extensive community screening in Taiwan.

Strict and repeated lockdowns have caused public fatigue regarding policy compliance and had a large impact on several countries' economies. We aimed to evaluate the effectiveness of a soft lockdown policy and the strategy of active community screening for controlling COVID-19 in Taiwan. We used village-based daily confirmed COVID-19 statistics in Taipei City and New Taipei City, between May 2, 2021, and July 17, 2021. The temporal Gi* statistic was used to compute the spatiotemporal hotspots. Simple linear regression was used to evaluate the trend of the epidemic, positivity rate from community screening, and mobility changes in COVID-19 cases and incidence before and after a level three alert in both cities. We used a Bayesian hierarchical zero-inflated Poisson model to estimate the daily infection risk. The cities accounted for 11,403 (81.17%) of 14,048 locally confirmed cases. The mean effective reproduction number (Re) surged before the level three alert and peaked on May 16, 2021, the day after the level three alert in Taipei City (Re = 3.66) and New Taipei City (Re = 3.37). Mobility reduction and a lower positive rate were positively associated with a lower number of cases and incidence. In the spatiotemporal view, seven major districts were identified with a radial spreading pattern from one hard-hit district. Villages with a higher inflow degree centrality among people aged ≥ 60 years, having confirmed cases, specific land-use types, and with a higher aging index had higher infection risks than other villages. Early soft lockdown policy and detection of infected patients showed an effective strategy to control COVID-19 in Taiwan.

Strategies to Ensure Continuity of Care Using Telemedicine with Older Adults during COVID-19: A Qualitative Study of Physicians in Primary Care and Geriatrics.

Objectives: Our objective was to interview primary care physicians (PCPs) and geriatricians on their experiences using telemedicine during the COVID-19 pandemic to examine strategies used to maintain continuity of care with their patients, ages 65 and older. Methods: Using purposive sampling, we selected physicians based on community size (metro/suburban/rural) and practice setting (academic/community) and conducted semi-structured interviews via Zoom (mean: 30 minutes). Interviews were recorded, transcribed, coded, and analyzed using framework analysis. Results: We enrolled 33 physicians (15 PCPs and 18 geriatricians) from July to November 2020. Findings indicate that many physicians successfully bridged the digital divide by: assessing patients' technological readiness in advance, being flexible with telehealth modes, using available home or facility-based staff, educating patients on telehealth privacy and usefulness, making accommodations for disabilities, and involving caregivers. Discussion: These findings can inform future policy and practice and assist physicians in resolving addressable barriers to telehealth use among older patients.

Self-Reported COVID-19 Infections and Social Mixing Behavior at Oncology Meetings.

PURPOSE: The COVID-19 pandemic largely suspended in-person scientific meetings because of risk of disease spread. In the era of vaccination and social distancing practices, meetings have begun returning to in-person formats. We surveyed attendees and potential attendees of 2 oncology meetings in the United States to identify rates of mixing behavior and the subsequent rate of self-reported COVID-19 infection. METHODS AND MATERIALS: We collected via survey reported social mixing behavior and COVID-19 positivity (within 21 days of meeting conclusion) of actual and potential in-person attendees of the American Society of Clinical Oncology (ASCO) Quality Care Symposium held September 24 to 25, 2021, and the American Society for Radiation Oncology (ASTRO) Annual Meeting held October 24 to 27, 2021. Conference speakers and other participants were identified through publicly available meeting materials and targeted via e-mail when possible. Recruitment of additional attendees and potential attendees was also conducted through a sharable link promoted via oncology newsletters and social media. Descriptive statistics alone were performed owing to low COVID-19 event rates. RESULTS: Response rates from targeted conference participants with publicly available e-mails were 27.4% for the ASCO and 14.3% for the ASTRO meetings. The ASCO survey produced 94 responses (48 in-person attendees). The ASTRO survey produced 370 responses (267 in-person attendees). Across both meetings, 3 of 308 (1.0%) in-person attendees versus 2 of 141 (1.4%) nonattendees tested positive for COVID-19. Low COVID-19 positivity rates were reported among in-person attendees spending more (>20) versus fewer (≤20) hours attending live sessions (2.2% vs 0%) and among indoor social event participants versus nonparticipants (0.8% vs 1.9%). Attendees largely felt comfortable attending additional in-person meetings after experiencing ASCO (87.5%) or ASTRO (91.9%) and felt mask compliance was good or excellent at ASCO (100%) and ASTRO (94.6%) meetings. CONCLUSIONS: In-person meetings do not seem to be contributing to high rates of new COVID-19 infections in the setting of vaccine and social distancing mandates, supporting paths forward for at least partially in-person conferences as COVID-19 becomes endemic.

Differential impacts of COVID-19 lockdowns on PM 2.5 across the United States.

The COVID-19 pandemic has induced large-scale behavioral changes, presenting a unique opportunity to study how air pollution is affected by societal shifts. At 455 PM 2.5 monitoring sites across the United States, we conduct a causal inference analysis to determine the impacts of COVID-19 lockdowns on PM 2.5 . Our approach allows for rigorous confounding adjustment with highly spatio-temporally resolved effect estimates. We find that, with the exception of the Southwest, most of the US experienced increases in PM 2.5 compared to concentrations expected under business-as-usual. To investigate possible drivers of this phenomenon, we use a regression model to characterize the relationship of various factors with the observed impacts. Our findings have immense environmental policy relevance, suggesting that mobility reductions alone may be insufficient to substantially and uniformly reduce PM 2.5 .

Impact of COVID-19 Pandemic on Patients' Perceptions of Safety and Need for Elective Foot and Ankle Surgery in the United States.

BACKGROUND: With the development of the COVID-19 pandemic, elective foot and ankle surgeries were delayed throughout the United States to divert health care resources and limit exposure. Little is known about the impact of COVID-19 on patient's willingness to proceed with elective procedures once restrictions are lifted and factors contributing to such decision. METHODS: Patients across 6 US orthopedic institutions who had their elective foot and ankle surgeries cancelled secondary to the pandemic were given a questionnaire. Specifically, patients were asked about their willingness to move forward with surgery once restrictions were lifted and if not why. Pain-level and pain medication use were also assessed. Univariate analysis was used to identify factors that contribute to patient's decisions. RESULTS: A total of 150 patients participated in this study. Twenty-one (14%) opted not to proceed with surgery once restrictions were lifted. Forty-three percent (n = 9) listed concern for COVID infection as the reason; however, 14% of them would proceed if procedures were performed in surgery center. Twenty-nine (19% of the total cohort) patients had increased pain and 11% of patients were taking more pain meds because of the delay to their procedure. Patients who decided not to proceed with surgery reported pain reduction (3% vs 14%) and lower increase in pain medication used (5% vs 12%). CONCLUSION: COVID-19 has made a significant impact on the health care system. Delay of elective foot and ankle procedures impact patient quality of life and outcomes. Access to surgery centers may provide a partial solution during the pandemic. LEVEL OF EVIDENCE: Level III.

Emergency physician perspectives on using telehealth with older adults during COVID-19: A qualitative study.

OBJECTIVES: Emergency medicine physicians have played a pivotal role throughout the coronavirus disease 19 (COVID-19) pandemic through in-person and remote management and treatment. Our primary objectives were to understand emergency medicine physicians' experiences using telehealth throughout the pandemic, any facilitators/barriers to successful usage, lessons learned during implementation, and successful/abandoned strategies used to engage with older adults. METHODS: Using a semi-structured interview guide, we conducted 30-min interviews. We used purposeful sampling to recruit emergency medicine physicians from all United States regions, rural-urban settings, and academic and community practices, who reported caring for patients 65 years or older in-person or virtually during the pandemic. Interviews were audio-recorded, transcribed, double-coded, and analyzed for emergent themes using framework analysis. RESULTS: A total of 15 in-depth interviews were completed from September to November 2020. Physicians had a median age of 37 years, 7 were women, and 9 had experience with telehealth before the pandemic. We identified several themes: (1) there were various motivations for telehealth use; (2) telehealth was used primarily to supplement, not replace in-person care; (3) most platforms were easy to use; (4) patients and caregivers had high acceptability of telemedicine; and (5) older adults with sensory and cognitive impairments often relied on caregivers. Emergency medicine physicians played a critical role during primary care office closures during the first wave-dispelling misinformation about COVID-19, triaging patients to testing and treatment, and providing care that would otherwise have been deferred. CONCLUSIONS: Our data show that telemedicine gained acceptability among emergency medicine physicians and provided options to patients who may have otherwise deferred care. These findings can inform future healthcare delivery for acute care needs or pandemic responses.

Studying SARS-CoV-2 infectivity and therapeutic responses with complex organoids.

Clinical management of patients with severe complications of COVID-19 has been hindered by a lack of effective drugs and a failure to capture the extensive heterogeneity of the disease with conventional methods. Here we review the emerging roles of complex organoids in the study of SARS-CoV-2 infection, modelling of COVID-19 disease pathology and in drug, antibody and vaccine development. We discuss opportunities for COVID-19 research and remaining challenges in the application of organoids.

Telehealth was beneficial during COVID-19 for older Americans: A qualitative study with physicians.

BACKGROUND: Individuals aged 65 and older face unique barriers to adoption of telehealth, and the coronavirus disease 2019 pandemic has provided a "natural experiment" in how to meet the health needs of older patients remotely. Physician perspectives on practical considerations surrounding telehealth adoption, motivations of use, and reasons for nonuse are necessary to inform the future of healthcare delivery. The objective is to understand the experiences of physicians using telemedicine for older patients. METHODS: From September to November 2020, we conducted 30-min semi-structured interviews using purposeful sampling to identify and enroll participants from diverse settings. We included 48 U.S.-based physicians (geriatrician, n = 18, primary care, n = 15, emergency, n = 15) from all geographic regions, rural-urban and academic/community settings. Audio-recorded interviews were professionally transcribed and analyzed using framework analysis. Major themes and subthemes were identified. RESULTS: Participants had a median (interquartile range) age of 37.5 (34-44.5), 27 (56%) were women. Five major themes emerged: (1) telehealth uptake was rapid and iterative, (2) telehealth improved the safety of medical care, (3) use cases were specialty-specific (for geriatricians and primary care physicians telehealth substituted for in-person visits; for emergency physicians it primarily supplemented in-person visits), (4) physicians altered clinical care to overcome older patient barriers to telehealth use, and (5) telehealth use among physicians declined in mid-April 2020, due primarily to patient needs and administrator preferences, not physician factors. CONCLUSION: In this qualitative analysis, physicians reported a rapid, iterative uptake of telehealth and attenuation of use as coronavirus disease 2019 prevalence declined. Physician experiences during the pandemic can inform interventions and policies to help buoy telehealth for ongoing healthcare delivery and ensure its accessibility for older Americans.

Residents' Physical Activities in Home Isolation and Its Relationship with Health Values and Well-Being: A Cross-Sectional Survey during the COVID-19 Social Quarantine.

The objective of the present study was to examine the associations between residents' physical activity, health values, and well-being during isolation. On the basis of the physical activity rating scale, health values scale, subjective well-being scale, and the satisfaction with life scale, we collected 505 valid questionnaires online from 31 provinces, municipalities, and autonomous regions in China. A series of multiple linear regression models were established to study the relationship between variables, and the bootstrap confidence interval was selected to test the mediating effect. The results showed that during the period of isolation, physical activity directly (b = 0.463, p < 0.001) or indirectly (b = 0.358, p < 0.001) had a positive impact on residents' well-being through the mediating effect of health values. There was a positive correlation between physical activity and health values (b = 0.710, p < 0.001), while health values had a direct positive association on well-being (b = 0.504, p < 0.001). In addition, a moderate amount of physical activity was found to be more associated with the well-being of residents during home isolation compared to small and large amounts of physical activity. This study shows the importance of residents' physical activities in home isolation. Moderate exercise at home and regular physical activity are beneficial to our physical and mental health, especially in terms of improving overall well-being.

The role of e-commerce in the urban food system under COVID-19: lessons from China

PurposeThe purpose of this study is to investigate e-commerce as a new means to ensure that the urban demand for food can be met during the coronavirus disease 2019 (COVID-19) outbreak. Because a number of COVID-19 e-commerce models have emerged, this paper discusses whether and (if so) why and how e-commerce can ensure the food supply for urban residents if social distancing becomes a norm and the transport and logistics systems are hindered.Design/methodology/approachThis study used qualitative research methods following the lack of empirical data. The authors referred to relevant literature, statistical data and official reports and comprehensively described the importance of e-commerce in ensuring the safety of food supply to Chinese urban residents under the impact of the epidemic. Corresponding to the traditional case study, this study presented a Chinese case on ensuring food supply through e-commerce during an epidemic.FindingsThe authors found that three e-commerce models played a substantial role in preventing the spread of the epidemic and ensuring the food supply for urban residents. The nationwide e-commerce platforms under market leadership played their roles by relying on the sound infrastructure of large cities and its logistics system was vulnerable to the epidemic. In the worst-affected areas, particularly in closed and isolated communities, the local e-commerce model was the primary model, supplemented by the unofficial e-commerce model based on social relations. Through online booking, centralized procurement and community distribution, the risk of cross infection could be effectively reduced and the food demand could be effectively satisfied. The theoretical explanation further verifies that, apart from e-commerce, a governance system that integrates the government, e-commerce platform, community streets and the unofficial guanxi also impels the success of these models.Originality/valueLessons from China are drawn for other countries struggling to deliver food to those in need under COVID-19. The study not only provides a solution that will ensure constant food supply to urban residents under the COVID-19 epidemic but also provides some reference for the maintenance of the food system of urban residents under the impact of a globalization-related crisis in future.
