Telehealth is increasingly used to provide specialty consultations to infants and children receiving care. However, there is uncertainty if the COVID-19 pandemic has influenced the use of telehealth among vulnerable populations.
This research aims to compare the overall use of tele–urgent care visits for pediatric patients before and after the pandemic, especially among vulnerable populations.
We conducted a cross-sectional analysis of pediatric tele–urgent care visits at a virtual care center at a southeastern health care center. The main outcome of this study was the use of pediatrics tele–urgent visits across geographical regions with different levels of social disparities and between 2019 and 2020.
Of 584 tele–urgent care visits, 388 (66.4%) visits occurred in 2020 during the pandemic compared to 196 (33.6%) visits in 2019. Among 808 North Carolina zip codes, 181 (22%) consisted of a high concentration of vulnerable populations, where 17.7% (56/317) of the tele–urgent care visits originated from. The majority (215/317, 67.8%) of tele–urgent care visits originated from zip codes with a low concentration of vulnerable populations. There was a significant association between the rate of COVID-19 cases and the concentration level of social factors in a given Zip Code Tabulation Area.
The use of tele–urgent care visits for pediatric care doubled during the COVID-19 pandemic. The majority of the tele–urgent care visits after COVID-19 originated from regions where there is a low presence of vulnerable populations. In addition, our geospatial analysis found that geographic regions with a high concentration of vulnerable populations had a significantly higher rate of COVID-19–confirmed cases and deaths compared to regions with a low concentration of vulnerable populations.
Pediatricians have used telehealth to provide a broad range of health care services among primary and specialty care [
Social determinants of health are paramount to the use of tele–urgent care because of the widening digital divide that occurs as a result of differences in individual socioeconomic characteristics [
We conducted a cross-sectional analysis of pediatric tele–urgent care visits at a virtual care center at a southeastern health care center. The virtual care center offers on-demand services to all patients older than 2 years regardless of their geographic location or medical affiliation to a health care system. Patients are required to create a profile through the virtual care center web portal and provide personal information such as age, gender, residential address, and insurance coverage. The web portal allows patients to choose from a list of providers based on the patient’s chief complaint. In addition, patients can choose between having an on-demand visit or scheduling a visit based on their preference and the availability of the provider. Board-certified physicians are available for on-demand televisits with the ability to prescribe and send medications to the patient’s choice of pharmacy.
The tele–urgent care visit data were received and preprocessed in Excel (Microsoft Corporation). All patients between the ages of 2 and 18 years were included in the analysis. Gender had three categories that were male, female, and nonbinary. Insurance type included the member ID and group ID if the patient provided insurance coverage information. Otherwise, the insurance field was empty, indicating the patient reported no insurance coverage.
The main outcome of this study was the use of pediatrics tele–urgent care visits across geographical regions with different levels of social disparities and between 2019 and 2020.
Since tele–urgent care participant data were collected and available at the zip level, Zip Code Tabulation Areas (ZCTAs; generalized areal representations of United States Postal Service zip code service areas) were used as the unit of analysis [
For this research, ZCTA-level social factors data was obtained from the ACS 2014-2018 5-year estimates, the most current 5-year data available from the ACS. We used percentages to account for population density for each social factor. Social factors used in the analyses were percent American Indian or Alaska Native people, percent of Black or African American people, percent in poverty, percent of single female headed households receiving Supplemental Nutrition Assistance Program (SNAP; formerly known as food stamps) with children younger than 18 years, percent of households receiving food stamps or SNAP with a person older than 60 years, total population receiving Medicare, and total population receiving Medicaid. For each variable, a threshold was set to determine if a ZCTA was
The maps were created using the computed social score for each ZCTA, as well as data on 2019 and 2020 telemedicine visits, and COVID-19 cases, aggregated to ZCTAs. For reference, urban centers throughout the state are labeled on the 2019 visits map. We used dot plot graphs to represent the number of visits coming from zip codes tagged with each of the listed social factors, tagged with no social factors, and the overall visit counts for each year for reference. Factors were sorted by the overall frequency of visits across both years.
Descriptive statistics, visualizations, and statistical tests were all performed in R (R Foundation for Statistical Computing) using ggplot2, version 4.0.2., and the maps were created using ArcGIS Pro 2.6.0 (Esri; July 28, 2020) and Illustrator 2020 24.3.0 (Adobe Inc; August 1, 2020). We primarily analyzed the data through descriptive tables and visualizations.
Of 584 tele–urgent care visits, 388 (66.4%) visits occurred in 2020 during the pandemic compared to 196 (33.6%) visits in 2019. Over half of the patients were male (112/196, 57%) in 2019, versus in 2020 when over half of the patients were female (202/388, 52%). For both years, the majority of patients reported having health insurance coverage. There was a larger gap between insured and uninsured patients in 2020, such that there were 265 (68%) insured patients and 123 (32%) uninsured patients (

This line graph shows the percentage of the total visits across the March to August time frame within the overall telemedicine population and broken down into the zip codes with and without social factors identified. The year 2019 shows more variation around the overall trend, reflecting a year not driven by COVID-19 and the smaller overall number of visits.
Visits from 2019 and 2020 were also compared geographically.
The number of tele–urgent care visits doubled in 2020 (n=317) compared to 2019 (n=155). In addition, the distribution of the visits covered more geographic locations in North Carolina compared to the visits in 2019 that were primarily around the Durham-Raleigh area (

We conducted a cross-sectional study of pediatrics tele–urgent care visits before and after the COVID-19 pandemic among vulnerable populations. We found that the volume of tele–urgent care visits for pediatrics doubled after the pandemic when compared to the year before, which can be explained by the shutdown of health care systems during the initial phases of the COVID-19 pandemic. Post–COVID-19, there was a substantial shift in patient characteristics seeking tele–urgent care for pediatrics such that there were more women and patients with health insurance coverage compared to pre–COVID-19. Most of the postpandemic visits originated from the metropolitan Raleigh region. This could be explained by several reasons including the shutdown of in-person nonessential visits during the initial phases of the pandemic. In addition, there were strict COVID-19 social gathering restrictions, and many schools transitioned to virtual classrooms.
Post–COVID-19, we reported an overall substantial increase in pediatric tele–urgent care visits. Regions characterized with high poverty and high concentration of African American people encountered the highest increase in visits among all examined social factors. The high demand among these communities demonstrates high disparities for tele–urgent care use for pediatrics care during the pandemic. We recommend future exploration of current infrastructure and culture to adopting tele–urgent care such that patients living in areas of high poverty may not have access to tele–urgent care equipment or internet access, which may hinder the adoption of tele–urgent care among vulnerable populations. Therefore, offering video and telephone visit options to vulnerable populations may improve adoption and use levels of tele–urgent care.
Telehealth provides a convenient delivery method of health care for pediatric patients; however, the impact of tele–urgent care on patient outcomes remains unknown. We recommend future investigation of the effect of tele–urgent care on emergency department visits and urgent care clinic visits. Moreover, prescription rates were found to be different between video and telephone visits [
There appears to be a relationship between social flags and change in tele–urgent care visits between 2019 and 2020. Although a sizeable minority of tele–urgent care visits occurred in regions with high concentrations of vulnerable populations, the majority of tele–urgent care visits occurred in zip codes with low concentrations of vulnerable populations. Post–COVID-19, the volume of tele–urgent care visits in regions with a high concentration of vulnerable populations was less when compared to pre–COVID-19. Although the reason for such a drop in visits is unclear, it is possible that loss of employment and new local tele–urgent care clinics may have attributed to the decrease in visits. In addition, it is possible that during the pandemic newly established tele–urgent care services available through local clinics and primary care providers were preferred by patients.
Post–COVID-19, there were two spikes in the volume of tele–urgent care visits in March and July 2020 among most vulnerable population groups compared to two spikes in 2019 in March and April. The post–COVID-19 increase may be associated with the sudden shutdown of in-person appointments across the state in March 2020 in response to the World Health Organization announcing COVID-19 as a global pandemic [
Telehealth use in pediatric care has shown major increase in use during the pandemic. In the future, telehealth may be a suitable health care delivery modality that complements in-office pediatric visits for established patients. Although telehealth use has increased during the pandemic, there remains unanswered questions around the effectiveness of telehealth in pediatric care and the quality of care [
This study has several limitations. Although the tele–urgent care data is statewide, it represents a single virtual care center. The patient demographic form did not include ethnic or racial information, which limited our ability to map patient-level ethnic data to zip code–level ethnic data. In the future, patient demographic forms will include ethnic and racial fields. The comparison of 2019 and 2020 data may include confounding factors including the effect of marketing campaigns and word of mouth in increasing the volume of tele–urgent care visits.
The use of tele–urgent care visits for pediatric care doubled during the COVID-19 pandemic. The majority of the tele–urgent care visits after COVID-19 originated from regions where there is a low presence of vulnerable populations. In addition, our geospatial analysis found that geographic regions with a high concentration of vulnerable populations had a significantly higher rate of COVID-19–confirmed cases and deaths compared to regions with a low concentration of vulnerable populations.
