Background In early 2020 New York City (NYC) was the epicenter of the COVID-19 pandemic in the US. Older adults were at especially high risk. Telemedicine (TM) was used to shift care from overburdened emergency departments (ED) to provide health care to a community in lock down. TM options presented unique challenges to our diverse older adult population including visual, hearing, cognitive and language limitations. Our objective was to evaluate the use of TM during the peak of the pandemic in NYC. Methods We conducted a retrospective chart review of patients 65 and older evaluated remotely via TM during our pandemic surge. Chart extraction was performed by six emergency physicians. Outcomes included demographics, technical limitations, rates of ED referral, and 30-day mortality. Results During the study period a total of 140 encounters were reviewed. The mean age was 73 years. Overall, 20% of patients in the cohort were emergently referred to the ED. Use of TH by this age cohort increased 20-fold as compared to a similar time frame pre pandemic. ED referral was highest in the those over 75; 45.9% (>75 yrs.). Forty three percent used family to assist. Thirty-day mortality was 7%. Conclusion TM use by older adults grew substantially at our institution during our initial COVID-19 surge. The same-day emergent referral rate and mortality rate reflect the high acuity represented in this cohort and points to the need for telehealth providers that are trained in triage and emergency medicine with a knowledge of local resource availability.

Background: The COVID-19 Pandemic in 2020 impacted more than 230 million people worldwide and caused over 500,000 deaths in the United States (US). It was estimated that in the first three months of the US pandemic more than 80% of the deaths were in those over 65 years 1 . In the spring of 2020, New York City was the US epicenter. Resources at city hospitals were limited. 2 There was a dramatic shift for all primary and non-emergency care to either be delayed or conducted via phone or Telehealth. These forms of remote health care monitoring offered patients and clinicians an opportunity to interface without the use of scarce personal protective equipment 3 .

There is a long history of using technology in low resourced areas and in disasters worldwide. In both natural and manmade disasters, telehealth has been used to assist clinicians on the ground with the use of video-link expert consultation and has been used by both military and peacetime health care providers. 4 More recently with hi-speed internet connections and the use of smart phones, a more comprehensive service can be provided.

Despite the potential innovations that telehealth present, certain patient populations may face logistical and other unique challenges in adopting such care platforms. Reaching older adults, presents unique challenges due to technology requirements, visual, hearing, and cognitive limitations. [5] [6] [7] Additionally, in diverse multilingual communities, translation services need to be readily available.

Importance: With a greater knowledge of telehealth platform limitations specific to older adults, we can improve services in the future. The peak of the pandemic in NYC required implementation of multiple disaster response plans. This study helps to identify and describe the utility and limitations of TM in serving the older adult population during a pandemic and can be used to model improved response in future disasters. The US Non English speaking population is increasing the 2016 American Community Survey found that over 21% of the population spoke a language other than English at home an increase from 18% in 2010. 8 The Columbia University Irving Medical Center/New York Presbyterian Hospital (CUIMC/ED) Emergency Department (ED) serves a multilingual urban population, thus we specifically described our patients' cultural and language needs.

This is a descriptive study of TM patients greater than 65 years old in which we describe the TM visits and problems that arise. Our primary objective was to describe the TM utilization amongst older adults during the peak of the pandemic in our ED and to compare usage to a similar time during the 2019 flu season. We also specifically compared the older adult age cohorts of 65-75, and >75 years to determine if there were differences in medical acuity and needs.

We conducted a retrospective chart review at an urban single-center academic medical center of patients greater than 65 years of age that utilized the Virtual Urgent Care program entitled "On Demand" platform from 3/1/2020-4/30/2020. Our Virtual Urgent Care program launched in 2018, is a TM platform, where patients outside the hospital setting (e.g. home, at work) are able to virtually connect and access a board certified emergency physician for a consultation and virtual exam/treatment plan, using a secure link on the hospital webpage. Users of this program were a mix of existing patients within our healthcare system who received targeted hospital messages regarding the TM services, alongside members of the public who came across the program through web searches. There were no new advertising initiatives during March/April 2020. Our daily total patient visit volume on the platform increased approximately twenty-fold during March and April of 2020 as compared to January/February 2020. The TM physicians were affiliated with (CUIMC/NYP) a quaternary academic medical center with 2 campuses in the borough of Manhattan.

The TM service was available to anyone calling from the state of New York. The Virtual Urgent care platform was staffed overwhelmingly by EM boarded physicians who are employed full time in the ED. The telehealth shift was a dedicated shift, but the same physicians had most of their clinical shifts providing in person ED care at the affiliated department. We developed and employed chart extraction tool for data acquisition. We additionally performed a deidentified electronic medical record (EMR) inquiry of TM visits by the same age cohort from 12/1/19 to 1/23/20 to determine TM frequency of use during a similar time span in the preceding influenza season. The study was approved by the local Institutional Review Board.

Eligible participants were identified through the electronic health records and included if they were 65 years of age or older with a Virtual Urgent Care "On Demand" visit note from 3/1/2020-4/30/2020 from a physician affiliated with the CUIMC/NYP west campus.

Measurements: Patient data was deidentified and entered a secure abstraction tool by six emergency medicine physicians. A legend for the abstraction tool was created by the six physicians so that data collection had consistency. The chart reviews were divided evenly amongst the physicians. Each physician was responsible for providing chart extraction of between 21 and 24 separate visits. Missing data was reported as such. An inter-rater reliability analysis was performed to ensure homogeneity and consensus among the data abstractors. All information was gathered solely through chart extraction of available notes in the EMR. Thirtyday mortality was only reported if the death was found in the EMR, of note the EMR in use is a large national platform and thus did include some deaths that occurred at other institutions that shared the same EMR system. We measured statistical correlation between age group cohort and gender, language, family assistance, living alone, technological difficulties, medication prescription, COVID like symptoms and same day referral to ED.

Median with first and third quartile was reported for continuous variables while frequency with percentage was reported for categorical variables by two age groups. Fisher's exact test was performed to assess the association between age and other categorical variables while Kruskal-Wallis test was performed to assess the association between age and other continuous variables.

We analyzed inter-rater reliability in multiple ways. First, we assumed independence among different ratings from the same physician and calculated the Cohen's kappa statistics for agreement and tested if the agreement happens by chance. 9 We also provided percentage agreement and 95% confidence interval. Analysis was conducted in RStudio Version 1.1.453. 10

Characteristics of study subjects: A total of 179 charts were pulled from the electronic health records of which 140 charts had eligible criteria. Of the 39 charts excluded, 15 had no notes documented, 8 were duplicates, and 16 did not meet criteria because the patient was not 65 years of age or older or did not have a Virtual Urgent Care visit. Of the charts with eligible criteria and reviewed, demographic information was collected and is illustrated in Table 1 .

Twenty-nine patients were referred to the ED urgently, of which four refused to go and 5% (n= 8) were directed to activate (or the provider activated) EMS by calling 911. The comparison of ED referral and age is shown in Table 1 . In comparing age and likelihood of urgent ED referral 45.9 % of those 75 years or greater were referred vs 12.9% of patients less than 75 years (p<0.001). Patients were assisted by family in 49 cases, 75% of patients greater than 75 used family assistance while only 30.5% of those less than 75 (p<0.001) used family to assist. We found charts were missing data related to the use of family assistance in 26 (18.5%) of the visits.

There were 10 deaths recorded with a known 30-day mortality rate of the TM cohort of 7%. The 30-day mortality rate of those referred to ED emergently was 10% and of those not emergently referred the 30-day Mortality was 6%. The 30-day mortality rate difference was not statistically significant between those greater than 75 and those less than 75 years (p=.46), ( 

Our descriptive study demonstrated a significant increase in telehealth utilization during the COVID-19 pandemic, suggesting the tremendous potential for use of such platforms by older adults during a disaster or public health emergency. We reached more patients of all ages via telehealth during the COVID-19 surge. We had a twenty-fold increase in TM usage amongst older adults when compared with a similar time in the influenza season.

We found most TM visits in this study were concerning for covid like illness (64.2%).

There were a significant number of calls (35.8%) related to other issues. This may represent patients who were unable or unwilling to receive care in an Emergency Department, Urgent Care Clinic, or doctor's office. This represents an opportunity to provide care while deferring visits from an overcrowded ED where it is difficult to isolate undifferentiated patients. From an infection control standpoint, TM provides a way to screen vulnerable patients while avoiding exposure to respiratory illnesses in an overcrowded environment.

Our data also points to room for improvement in the technology interface with older adults using remote health care. Just under half (43%) of the calls used family members to assist the patient, this was significantly more common in those greater than 75 years. Only 6% of the charts reviewed showed evidence of an interrupted visit but we suspect technical difficulties were far more frequent as we do not have the statistics related to the TM visits not able to be connected to clinician. Just over 30% of the calls were made by non-English speakers which points to the need of not only the clinician visits to be multilingual but the instructions to connect also be multilingual. When older patients are seen in the ED hands on instruction with their mobile phone or device would be one way to increase appropriate use of telehealth services.

Multilingual written instructions and training designated family members would also increase availability of TM services to older adults.

Telehealth program development is often thought to be a way to defer non-emergent care, but we found many patients with high medical acuity. In fact, 21.7% (n=30) of the cases were referred emergently to the ED. As expected, same day ED referral was more significant in the greater than 75 age group. There were 10 known deaths of this cohort during the study period giving us a known 30-day mortality rate of 7% of this cohort of telehealth users.

Limitations: There are several limitations to this study. First, as a study carried out at a single site generalizability of the results to other clinical contexts may be limited. Additionally, determination of visits with family assistance, technological problems, or language problems were based only on what was documented in medical records as we did not have access to the software platform statistics of incomplete registration or dropped videocalls that occurred prior to connecting with the clinician. This data was missing in many of the charts. We are also limited by the clinician's likelihood of noting these concerns as this was not a required format of the note. Thirty-day mortality includes only mortality recorded in the EMR and thus may be underrepresented if the death was recorded outside this Institution's EMR.

Consumer bias could impact the type of patients that use Virtual Urgent Care, and therefore affect the outcome of the results. Lastly, the patient population that the platform serves is limited to discrete geographic regions. Internally, the small sample size of 140 patients potentially affects overall power.

In summary our study points to not only acceptance of telehealth by older adults in a disaster situation but also some of the pitfalls and technological difficulties. One of the most important findings was that the high medical acuity required emergency medicine trained physicians that are also actively working clinically within the same health care system.

Many of the findings in this study were used to formulate practice standards of our developing TM program. In addition, knowledge of real time ED Capacity, and EMS response time are important factors to consider when responding to a community wide disaster or epidemic.

Ultimately future work focused on the efficacy and implementation of TM may help us gain greater understanding of TM as an exciting platform with unique opportunities and challenges to better serve and support older adult patients.

The COVID 19 pandemic has by necessity required the use of new ways to provide health care, this study provides an initial evaluation of the use of remote health care to provide emergency and urgent care to older adults in a safe environment. It is important that new modalities be evaluated in a systematic way.

2. What does this study attempt to show? It describes the successes and limitations of healthcare delivery to older adults via Telemedicine.

3. What are the key findings? There was a 20-fold increase in the use of telemedicine in the older adult cohort during the study period as compared to the preceding influenza peak. Most adults >75 years old required family assistance. Older adults using telehealth often required emergent referral to the Emergency Department. Is there a concern for COVID like illness?
