Meeting the challenges of retention and enrollment of study participants in clinical trials during the COVID-19 pandemic from the study leadership perspective: Experience from the Zoster Eye Disease Study (ZEDS)
Tom, MeeLee; Cohen, Elisabeth J; LopezJimenez, Carlos; Hochman, Judith S; Troxel, Andrea B; Jeng, Bennie H
Purpose/UNASSIGNED:To describe steps taken that enabled a high rate of retention and early resumption of enrollment in the Zoster Eye Disease Study (ZEDS), a randomized controlled trial funded by the National Eye Institute, during the first 13 months (3/1/2020-3/31/2021) of the COVID-19 pandemic. Methods/UNASSIGNED:A number of responses were implemented in ZEDS when the focus shifted to retention of study participants at the beginning of the pandemic including frequent communication with the participating clinical centers (PCCs) about remote visits, local lab work, shipping study medication, and completion of revised case report forms. Additional payments were provided to the PCCs. Remote activation of PCCs continued. Screening and enrollment visits gradually resumed when allowed. Results/UNASSIGNED:Communication with PCCs increased, and average attendance at monthly coordinator teleconferences went up from 17 to 47. Remote visits peaked in April 2020, accounting for 75% (33/44) of study visits, then declined to less than 10% of study visits beginning August 2020. Overall, 97% (590/609) of study visits were completed. Only 5.5% (9/165) of study participants withdrew consent, and 2.4% (4/165) were lost to follow-up. Enrollment returned to pre-pandemic levels by September 2020. Discussion/UNASSIGNED:Strong communication and unwavering commitment, combined with the technological capability for remote work, visits, and shipment of study medication, were key to the successful retention of study participants and resumption of enrollment. Conclusions/UNASSIGNED:Rapid responses to challenges to trials caused by the COVID-19 pandemic can enable them to continue successfully and provide insights into the planning of future trials.

BACKGROUND:Toxic metabolic encephalopathy (TME) has been reported in 7-31% of hospitalized patients with coronavirus disease 2019 (COVID-19); however, some reports include sedation-related delirium and few data exist on the etiology of TME. We aimed to identify the prevalence, etiologies, and mortality rates associated with TME in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-positive patients. METHODS:We conducted a retrospective, multicenter, observational cohort study among patients with reverse transcriptase-polymerase chain reaction-confirmed SARS-CoV-2 infection hospitalized at four New York City hospitals in the same health network between March 1, 2020, and May 20, 2020. TME was diagnosed in patients with altered mental status off sedation or after an adequate sedation washout. Patients with structural brain disease, seizures, or primary neurological diagnoses were excluded. The coprimary outcomes were the prevalence of TME stratified by etiology and in-hospital mortality (excluding comfort care only patients) assessed by using a multivariable time-dependent Cox proportional hazards models with adjustment for age, race, sex, intubation, intensive care unit requirement, Sequential Organ Failure Assessment scores, hospital location, and date of admission. RESULTS:Among 4491 patients with COVID-19, 559 (12%) were diagnosed with TME, of whom 435 of 559 (78%) developed encephalopathy immediately prior to hospital admission. The most common etiologies were septic encephalopathy (n = 247 of 559 [62%]), hypoxic-ischemic encephalopathy (HIE) (n = 331 of 559 [59%]), and uremia (n = 156 of 559 [28%]). Multiple etiologies were present in 435 (78%) patients. Compared with those without TME (n = 3932), patients with TME were older (76 vs. 62 years), had dementia (27% vs. 3%) or psychiatric history (20% vs. 10%), were more often intubated (37% vs. 20%), had a longer hospital length of stay (7.9 vs. 6.0 days), and were less often discharged home (25% vs. 66% [all P < 0.001]). Excluding comfort care patients (n = 267 of 4491 [6%]) and after adjustment for confounders, TME remained associated with increased risk of in-hospital death (n = 128 of 425 [30%] patients with TME died, compared with n = 600 of 3799 [16%] patients without TME; adjusted hazard ratio [aHR] 1.24, 95% confidence interval [CI] 1.02-1.52, P = 0.031), and TME due to hypoxemia conferred the highest risk (n = 97 of 233 [42%] patients with HIE died, compared with n = 631 of 3991 [16%] patients without HIE; aHR 1.56, 95% CI 1.21-2.00, P = 0.001). CONCLUSIONS:TME occurred in one in eight hospitalized patients with COVID-19, was typically multifactorial, and was most often due to hypoxemia, sepsis, and uremia. After we adjustment for confounding factors, TME was associated with a 24% increased risk of in-hospital mortality.

BACKGROUND:A number of studies have identified patient-, provider-, and community-level barriers to effective diabetes management among South Asian Americans, who have a high prevalence of type 2 diabetes. However, no multi-level, integrated community health worker (CHW) models leveraging health information technology (HIT) have been developed to mitigate disease among this population. This paper describes the protocol for a multi-level, community-clinical linkage intervention to improve glycemic control among South Asians with uncontrolled diabetes. METHODS:The study includes three components: 1) building the capacity of primary care practices (PCPs) to utilize electronic health record (EHR) registries to identify patients with uncontrolled diabetes; 2) delivery of a culturally- and linguistically-adapted CHW intervention to improve diabetes self-management; and 3) HIT-enabled linkage to culturally-relevant community resources. The CHW intervention component includes a randomized controlled trial consisting of group education sessions on diabetes management, physical activity, and diet/nutrition. South Asian individuals with type 2 diabetes are recruited from 20 PCPs throughout NYC and randomized at the individual level within each PCP site. A total of 886 individuals will be randomized into treatment or control groups; EHR data collection occurs at screening, 6-, 12-, and 18-month. We hypothesize that individuals receiving the multi-level diabetes management intervention will be 15% more likely than the control group to achieve ≥0.5% point reduction in hemoglobin A1c (HbA1c) at 6-months. Secondary outcomes include change in weight, body mass index, and LDL cholesterol; the increased use of community and social services; and increased health self-efficacy. Additionally, a cost-effectiveness analysis will focus on implementation and healthcare utilization costs to determine the incremental cost per person achieving an HbA1c change of ≥0.5%. DISCUSSION/CONCLUSIONS:Final outcomes will provide evidence regarding the effectiveness of a multi-level, integrated EHR-CHW intervention, implemented in small PCP settings to promote diabetes control among an underserved South Asian population. The study leverages multisectoral partnerships, including the local health department, a healthcare payer, and EHR vendors. Study findings will have important implications for the translation of integrated evidence-based strategies to other minority communities and in under-resourced primary care settings. TRIAL REGISTRATION/BACKGROUND:This study was registered with clinicaltrials.gov: NCT03333044 on November 6, 2017.

COVID-19 and ischemic stroke
Sagris, Dimitrios; Papanikolaou, Aikaterini; Kvernland, Alexandra; Korompoki, Eleni; Frontera, Jennifer A; Troxel, Andrea B; Gavriatopoulou, Maria; Milionis, Haralampos; Lip, Gregory Y H; Michel, Patrik; Yaghi, Shadi; Ntaios, George
Since the onset of the COVID-19 pandemic, a substantial proportion of COVID-19 patients had documented thrombotic complications and ischemic stroke. Several mechanisms related to immune mediated thrombosis, the renin angiotensin system, and the effect of SARS-CoV-2 in cardiac and brain tissue may contribute to the pathogenesis of ischemic stroke in patients with COVID-19. Simultaneously, significant strains on global healthcare delivery, including ischemic stroke management, have made treatment of stroke in the setting of COVID-19 particularly challenging. In this review we summarize the current knowledge on epidemiology, clinical manifestation and pathophysiology of ischemic stroke in patients with COVID-19 to bridge the gap from bench to bedside and clinical practice during the most challenging global health crisis of the last decades.

Prospective individual patient data meta-analysis: Evaluating convalescent plasma for COVID-19
Goldfeld, Keith S; Wu, Danni; Tarpey, Thaddeus; Liu, Mengling; Wu, Yinxiang; Troxel, Andrea B; Petkova, Eva
As the world faced the devastation of the COVID-19 pandemic in late 2019 and early 2020, numerous clinical trials were initiated in many locations in an effort to establish the efficacy (or lack thereof) of potential treatments. As the pandemic has been shifting locations rapidly, individual studies have been at risk of failing to meet recruitment targets because of declining numbers of eligible patients with COVID-19 encountered at participating sites. It has become clear that it might take several more COVID-19 surges at the same location to achieve full enrollment and to find answers about what treatments are effective for this disease. This paper proposes an innovative approach for pooling patient-level data from multiple ongoing randomized clinical trials (RCTs) that have not been configured as a network of sites. We present the statistical analysis plan of a prospective individual patient data (IPD) meta-analysis (MA) from ongoing RCTs of convalescent plasma (CP). We employ an adaptive Bayesian approach for continuously monitoring the accumulating pooled data via posterior probabilities for safety, efficacy, and harm. Although we focus on RCTs for CP and address specific challenges related to CP treatment for COVID-19, the proposed framework is generally applicable to pooling data from RCTs for other therapies and disease settings in order to find answers in weeks or months, rather than years.

A Behavioral Economics-Electronic Health Record Module to Promote Appropriate Diabetes Management in Older Adults: Protocol for a Pragmatic Cluster Randomized Controlled Trial
Belli, Hayley M; Troxel, Andrea B; Blecker, Saul B; Anderman, Judd; Wong, Christina; Martinez, Tiffany R; Mann, Devin M
BACKGROUND:The integration of behavioral economics (BE) principles and electronic health records (EHRs) using clinical decision support (CDS) tools is a novel approach to improving health outcomes. Meanwhile, the American Geriatrics Society has created the Choosing Wisely (CW) initiative to promote less aggressive glycemic targets and reduction in pharmacologic therapy in older adults with type 2 diabetes mellitus. To date, few studies have shown the effectiveness of combined BE and EHR approaches for managing chronic conditions, and none have addressed guideline-driven deprescribing specifically in type 2 diabetes. We previously conducted a pilot study aimed at promoting appropriate CW guideline adherence using BE nudges and EHRs embedded within CDS tools at 5 clinics within the New York University Langone Health (NYULH) system. The BE-EHR module intervention was tested for usability, adoption, and early effectiveness. Preliminary results suggested a modest improvement of 5.1% in CW compliance. OBJECTIVE:This paper presents the protocol for a study that will investigate the effectiveness of a BE-EHR module intervention that leverages BE nudges with EHR technology and CDS tools to reduce overtreatment of type 2 diabetes in adults aged 76 years and older, per the CW guideline. METHODS:A pragmatic, investigator-blind, cluster randomized controlled trial was designed to evaluate the BE-EHR module. A total of 66 NYULH clinics will be randomized 1:1 to receive for 18 months either (1) a 6-component BE-EHR module intervention + standard care within the NYULH EHR, or (2) standard care only. The intervention will be administered to clinicians during any patient encounter (eg, in person, telemedicine, medication refill, etc). The primary outcome will be patient-level CW compliance. Secondary outcomes will measure the frequency of intervention component firings within the NYULH EHR, and provider utilization and interaction with the BE-EHR module components. RESULTS:Study recruitment commenced on December 7, 2020, with the activation of all 6 BE-EHR components in the NYULH EHR. CONCLUSIONS:This study will test the effectiveness of a previously developed, iteratively refined, user-tested, and pilot-tested BE-EHR module aimed at providing appropriate diabetes care to elderly adults, compared to usual care via a cluster randomized controlled trial. This innovative research will be the first pragmatic randomized controlled trial to use BE principles embedded within the EHR and delivered using CDS tools to specifically promote CW guideline adherence in type 2 diabetes. The study will also collect valuable information on clinician workflow and interaction with the BE-EHR module, guiding future research in optimizing the timely delivery of BE nudges within CDS tools. This work will address the effectiveness of BE-inspired interventions in diabetes and chronic disease management.

A randomized trial of exercise and diet on health-related quality of life in survivors of breast cancer with overweight or obesity
Brown, Justin C; Sarwer, David B; Troxel, Andrea B; Sturgeon, Kathleen; DeMichele, Angela M; Denlinger, Crystal S; Schmitz, Kathryn H
BACKGROUND:Obesity is a chronic, relapsing, and progressive disease; it is associated with poor health-related quality of life (HRQOL) in survivors of breast cancer. METHODS:In this 2 × 2 factorial trial, 351 survivors of breast cancer with overweight or obesity were randomized to 1 of 4 treatment groups for 52 weeks: control, exercise alone, diet alone, or exercise plus diet. HRQOL end points were measured at baseline and at week 52 using the 36-Item Medical Outcomes Survey-Short Form (SF-36). Repeated measures analysis of covariance quantified the estimated treatment difference (ETD). RESULTS:(5.9), and 71 participants (20.2%) self-reported fair or poor general health. After 52 weeks, compared with control, the exercise plus diet improved the physical health summary score (ETD: 5.39; 95% CI, 0.55-10.22); exercise alone (ETD: -1.91; 95% CI, -6.60 to 2.79) and diet alone (ETD: 3.16; 95% CI, -1.52 to 7.83) did not change the physical health summary score. Compared with control, exercise alone (ETD: -0.27; 95% CI, -6.60 to 2.79), diet alone (ETD: 3.25; 95% CI, -1.41 to 7.91), and the exercise plus diet (ETD: 1.75; 95% CI, -2.90 to 6.39) did not change the mental health summary score. Exercise alone did not impact any HRQOL subscale; diet alone improved the vitality subscale; exercise plus diet improved the physical functioning, role-physical and vitality subscales. CONCLUSION/CONCLUSIONS:In survivors of breast cancer with overweight or obesity, exercise plus diet improved select HRQOL end points at week 52.

Acceptability of capnography-assisted respiratory therapy: a new mind-body intervention for COPD
Norweg, Anna Migliore; Skamai, Anne; Kwon, Simona C; Whiteson, Jonathan; MacDonald, Kyle; Haas, Francois; Collins, Eileen G; Goldring, Roberta M; Reibman, Joan; Wu, Yinxiang; Sweeney, Greg; Pierre, Alicia; Troxel, Andrea B; Ehrlich-Jones, Linda; Simon, Naomi M
Dyspnoea self-management is often suboptimal for patients with COPD. Many patients with COPD experience chronic dyspnoea as distressing and disabling, especially during physical activities. Breathing therapy is a behavioural intervention that targets reducing the distress and impact of dyspnoea on exertion in daily living. Using a qualitative design, we conducted interviews with 14 patients after they participated in a novel mind-body breathing therapy intervention adjunct, capnography-assisted respiratory therapy (CART), combined with outpatient pulmonary rehabilitation. Comprehensive CART consisted of patient-centred biofeedback, tailored breathing exercises, a home exercise programme and motivational interviewing counselling. We assessed participants' perceptions and reported experiences to gauge the acceptability of CART and refine CART based on feedback. Constant comparative analysis was used to identify commonalities and themes. We identified three main themes relating to the acceptability and reported benefits of CART: (1) self-regulating breathing; (2) impact on health; and (3) patient satisfaction. Our findings were used to refine and optimise CART (i.e. its intensity, timing and format) for COPD. By addressing dysfunctional breathing behaviours and dysregulated interoception, CART offers a promising new paradigm for relieving dyspnoea and related anxiety in patients with COPD.

Dominance of Alpha and Iota variants in SARS-CoV-2 vaccine breakthrough infections in New York City
Duerr, Ralf; Dimartino, Dacia; Marier, Christian; Zappile, Paul; Wang, Guiqing; Lighter, Jennifer; Elbel, Brian; Troxel, Andrea B; Heguy, Adriana
The efficacy of COVID-19 mRNA vaccines is high, but breakthrough infections still occur. We compared the SARS-CoV-2 genomes of 76 breakthrough cases after full vaccination with BNT162b2 (Pfizer/BioNTech), mRNA-1273 (Moderna), or JNJ-78436735 (Janssen) to unvaccinated controls (February-April 2021) in metropolitan New York, including their phylogenetic relationship, distribution of variants, and full spike mutation profiles. The median age of patients in the study was 48 years; 7 required hospitalization and 1 died. Most breakthrough infections (57/76) occurred with B.1.1.7 (Alpha) or B.1.526 (Iota). Among the 7 hospitalized cases, 4 were infected with B.1.1.7, including 1 death. Both unmatched and matched statistical analyses considering age, sex, vaccine type, and study month as covariates supported the null hypothesis of equal variant distributions between vaccinated and unvaccinated in χ2 and McNemar tests (P > 0.1), highlighting a high vaccine efficacy against B.1.1.7 and B.1.526. There was no clear association among breakthroughs between type of vaccine received and variant. In the vaccinated group, spike mutations in the N-terminal domain and receptor-binding domain that have been associated with immune evasion were overrepresented. The evolving dynamic of SARS-CoV-2 variants requires broad genomic analyses of breakthrough infections to provide real-life information on immune escape mediated by circulating variants and their spike mutations.

BACKGROUND:Colorectal cancer is the second leading cause of cancer death among Hispanic Americans. Puerto Ricans are the second largest Hispanic subgroup in the USA and the largest in New York City, but little is known about predictors of colorectal cancer screening uptake in this population. AIMS/OBJECTIVE:We used the New York City Community Health Survey, a population-based telephone survey, to investigate predictors of up-to-date colonoscopy use over time among Puerto Ricans aged ≥ 50 years in NYC. METHODS:We assessed the association between sociodemographic and medical factors and up-to-date colonoscopy use (defined as colonoscopy within the last 10 years) using univariable and multivariable logistic regression over six time periods: 2003-2005, 2006-2008, 2009-2010, 2011-2012, 2013-2014, and 2015-2016. RESULTS:On multivariable analysis, age ≥ 65 years (OR 1.64-1.93 over three periods) and influenza vaccination (OR 1.86-2.17 over five periods) were the two factors most consistently associated with up-to-date colonoscopy use. Individuals without a primary care provider (OR 0.38-0.50 over three periods) and who did not exercise (OR 0.49-0.52 over two periods) were significantly less likely to have an up-to-date colonoscopy. CONCLUSIONS:Older age, influenza vaccination, having a primary care provider, and exercise are independent predictors of up-to-date colonoscopy use among Puerto Ricans in NYC. Interventions to improve screening colonoscopy uptake among Puerto Ricans should be targeted to those aged 50-64 years and who do not have a primary care provider.
