Adapting Alzheimer Disease and Related Dementias Clinical Research Evaluations in the Age of COVID-19.

In March 2020, the novel coronavirus (COVID-19) became a global pandemic that would cause most in-person visits for clinical studies to be put on pause. Coupled with protective stay at home guidelines, clinical research at the Icahn School of Medicine at Mount Sinai Alzheimer's Disease Research Center (ISMMS ADRC) needed to quickly adapt to remain operational and maintain our cohort of research participants. Data collected by the ISMMS ADRC as well as from other National Institute on Aging (NIA) Alzheimer Disease centers, follows the guidance of the National Alzheimer Coordinating Center (NACC). However, at the start of this pandemic, NACC had no alternative data collection mechanisms that could accommodate these safety guidelines. To stay in touch with our cohort and to ensure continued data collection under different stages of quarantine, the ISMMS ADRC redeployed their work force to continue their observational study via telehealth assessment. On the basis of this experience and that of other centers, NACC was able to create a data collection process to accommodate remote assessment in mid-August. Here we review our experience in filling the gap during this period of isolation and describe the adaptations for clinical research, which informed the national dialog for conducting dementia research in the age of COVID-19 and beyond.

Socio-psychological impact of COVID-19 on a diverse cohort of older adult research participants in New York

Background During the spring of 2020, New York was overwhelmed by COVID-19 and older adults as well as ethnic minorities were disproportionately affected. The Alzheimer?s Disease Research Center (ADRC) located in East Harlem in New York City, serves a predominantly low income, Latinx community. It was imperative to gauge the impact of COVID-19 on our diverse group of older adult research participants. Method Participants enrolled in the ADRC with a Clinical Dementia Rating Scale of 0 (75%) or .5 (24%) completed evaluations between May and December 2020 for the National Alzheimer?s Cooperative Center Uniform Data Set (NACC UDS) and were administered a 33-item COVID-19 questionnaire over the telephone that was modified from the questionnaire provided by NACC. The 15?20 minute survey asked questions about social, psychological, and emotional experiences with COVID-19, including whether they had lost a loved one to COVID, as well as items targeting the psychological sequelae of the pandemic (depression, isolation, a sense of loss of control, for example). Result 198 participants completed the questionnaire. Of these, 55% were non-Hispanic White, 15% were non-Hispanic Black, 14% were Hispanic, and 16% were Asian. The overall sample?s mean age was 76.4±7.5, mean education 15.80±3.1years, and 62.6% were male. Survey results indicated that 89% felt the pandemic had been disruptive to their lives, and 30% had lost a loved one to COVID. Sixty-three percent of participants reported being in touch remotely with friends or family nearly every day, and 24% 2-3x/week. Thirty two percent reported feeling they could not control important things in their life and feeling anxious (46%), bored (41%), and lonely (30%). Twenty seven percent reported feeling depressed and 23% experienced sleep problems. Conclusion In this diverse sample of community dwelling older adults, most were able to remain in close contact with family and friends, and many reported the pandemic as disruptive. However, fewer reported experiencing a loss of control as well as psychological or emotional distress (i.e., depression) which may reflect adaptive mechanisms worthy of further study.

Smartphone ownership and usage in Chinese- and English-speaking older adults.

BACKGROUND: Data collection by smartphone is becoming more widespread in healthcare research. Previous studies reported racial/ethnical differences in the use of digital health technology. However, cross-language group comparison (Chinese- and English-speaking older adults) were not performed in these studies. This project will expand to smartphone technology use in diverse older populations with a focus on Chinese American older adults who are monolingual Chinese-speakers. METHOD: The Alzheimer's Disease Research Center (ADRC) at Icahn School of Medicine at Mount Sinai (ISMMS) evaluates diverse older populations using National Alzheimer's Coordinating Center's Uniform Data Set (NACC UDS). The UDS has different language versions, including English and Chinese. The evaluation includes a medical examination, cognitive assessments, and a research blood draw. Smartphone ownership and usage were captured using a local questionnaire developed by our ADRC. The questionnaire, available in English and Chinese, was administered by our ADRC coordinators during the COVID-19 pandemic. Multivariate analysis of variance (MANOVA) was used to examine differences in technology ownership and usages between the two language groups, while controlling for age, gender, education, and cognitive status (measured by Clinical Dementia Rating). RESULT: 33 Chinese- and 117 English-speaking older adults who received a diagnosis of normal cognition or mild cognitive impairment at consensus were included in the data analysis. Results reveal a high prevalence of smartphone ownership in our Chinese- (100%) and English-speaking older participants (86.3%). Participants in both language groups use mobile technology for a wide range of purposes, such as getting news and other information (Chinese=90.9%; English=87.2%), sending/receiving text (Chinese=97.0%; English=96.6%), watching videos/TV shows (Chinese=78.8%; English=69.2%), and taking classes (Chinese=57.5%; English=57.3%). However, Chinese-speaking older adults were less likely than English-speaking older adults to use mobile technology to post their own reviews or comments online (Chinese=9.1%; English=39.3%, p=0.001), download or purchase an app (Chinese=21.2%; English=70.9%, p<0.001), track health/ fitness via apps/website (Chinese=12.1%; English=47.9%, p<0.001) and manage/receive medical care (Chinese=15.2%; English=67.5%, p<0.001). CONCLUSION: Our findings highlight potential barriers to smartphone usage in Chinese American older adults with limited English proficiency. The results have implications for how smartphone technology can be used in clinical practice and aging research.
