The aim of this study is to examine the association between patient characteristics and primary care telemedicine choice among integrated delivery system patients self-scheduling visits during the COVID-19 pandemic. We used multivariate logistic regression to examine the association between the choice of video versus telephone and patient sociodemographic characteristics and technology access among patient-initiated primary care telemedicine visits scheduled online from March to October 2020. Among 978 272 patient-scheduled primary care telemedicine visits, 39% were video visits. Patients of Black or Hispanic race/ethnicity, or living in low socioeconomic status or low internet access neighborhoods were less likely to schedule video visits. Patients 65 years or older, with prior video visit experience or mobile portal access, or visiting their own personal provider were more likely to schedule video visits. While video adoption was substantial in all patient groups examined, differences in telemedicine choice suggest the persistence of a digital divide, emphasizing the importance of maintaining a telephone telemedicine option.

The COVID-19 pandemic has dramatically changed the way health care is delivered, with telemedicine broadly promoted and widely adopted for social distancing. [1] [2] [3] While live patient-physician video telemedicine more closely approximates an in-person visit, telephone telemedicine also offers patients convenient real-time access to care without potential exposure to the virus. There is limited evidence on patient preference for video or telephone telemedicine primary care visits during the pandemic. In this time of crisis-based practice change, we studied patient characteristics associated with the choice of video versus telephone telemedicine among members of an integrated care delivery system who self-scheduled primary care visits.

This study was conducted in Kaiser Permanente Northern California (KPNC), which had adopted telephone visits over a decade ago and implemented video visit technology in 2014 with strong patient satisfaction. 4, 5 In early March 2020, in order to support social distancing, medical group leadership removed the option for patients to self-schedule in-person visits through the online patient portal. All patients self-scheduling an appointment had to choose either a telephone or a video visit with comparable scheduling availability. Inperson visits were still available, but only based on a physician's recommendation after an initial telemedicine visit. These protocols continued throughout the study period.

We examined all patient-initiated primary care telemedicine visits scheduled through the patient portal from March 16 (start of local shelter-in-place order) to October 31, 2020, and used multivariate logistic regression to examine the associations between patient choice of video versus telephone visit and patient sociodemographic characteristics (age, sex, race/ethnicity, and neighborhood socioeconomic status), technology access (neighborhood-level residential high-speed internet access, prior video visit, prior mobile portal use), and whether the visit was with patient's own personal primary care provider (PCP). Based on the patients' residential addresses, we defined low neighborhood socioeconomic status (SES) if at least 20% of residents have household incomes below the federal poverty level or at least 25% of residents 25 years of age or older have less than a high school education in the census block group using 2010 US census measures, 6 and low neighborhood residential high-speed internet access level if less than 80% of households have a residential fixed high-speed connection (at least 10 Mbps downstream and at least 1 Mbps upstream) in the census tract using Federal Communications Commission data. As additional measures of prior technology access, we captured patients' mobile portal use in the prior 365 days as a measure of prior mobile device access and use of any video visit in the prior 365 days as a measure of prior video visit experience. The multivariate model controlled for patient medical problem (ICD10 code grouping 7 of primary diagnosis), time trend (an indicator variable for week), and KPNC Medical Center, with standard errors adjusted for repeated visits within patients. For easier interpretation, we calculated the adjusted rate of video visits in telemedicine by patient characteristics using the coefficients from multivariate logistic regression. We used Stata 14.2 (StataCorp, Texas) for all analyses.

The study was approved by the Kaiser Foundation Research Institute's Institutional Review Board. Waiver of informed consent was obtained due to the observational nature of the study.

There were 978 272 primary care telemedicine visits scheduled using the patient portal during the study period. Overall, 11.0% of patients were pediatric (age< 18) and 15.7% were 65 years or older, 42.4% were male, and 47.5% were patients of White race/ethnicity; 20.3% lived in a neighborhood categorized as low SES and 40.1% lived in a neighborhood with low internet access level; 29.0% of patients had at least one video visit in prior 365 days and 60.6% had mobile portal access in prior 365 days; 75.9% of the visits were with patients' own personal PCP (Table 1) .

Overall, 39.4% of the patient-scheduled visits during the study period were scheduled as video visits and 60.6% were scheduled as telephone visits. The highest rate of video visits (60.9%) was found among visits with diagnosis of skin problems (ICD10: L00-L99), followed by 57.6% among visits with diagnosis of eye problems (ICD10: H00-H59). The rate of video visits varied significantly by diagnoses (P < .05). The proportion of video visits in telemedicine increased dramatically over time during the study period, from less than 7% in the first week of the study period to 40% in the first week of June, and 46% by the end of the study period in last week of October ( Figure 1 ).

After adjustment, all the patient characteristics examined were statistically significantly associated with the choice of video versus telephone visits ( Figure 2 

With the ongoing COVID-19 pandemic, telemedicine provides patients the option to seek primary care without the potential virus exposure, but preference and capability for video telemedicine may be different between patients. Among patient-scheduled primary care telemedicine visits in a large integrated health care delivery system, we found patients' choice of video versus telephone appointment varied by patient demographics and technology access. For example, Black or Hispanic patients or patients living in low SES or low internet access neighborhoods were less likely to choose video visits. Those with technology access, either prior video visit experience or mobile device access, were more likely to choose video visits. Still, while we found different adoption rates of video visits by patient characteristics, ranging from 35.4% to 50.3% across specific patient subgroups, the adoption rates were relatively high in all ex-amined groups and no specific group was completely left out of video telemedicine.

The findings from this large study represent unique pandemicrelated shifts in use of telemedicine, at a time when patient visits scheduled using the portal were limited to telephone or video. While this study confirmed the association of Black or Hispanic race/ethnicity and low SES neighborhood with low video visit use from other studies during the pandemic, [8] [9] [10] [11] some of the findings appear different from previous studies. We found Asian patients were more likely to choose video visits as compared with patients of White race, which is different from another study examining video visit during the pandemic. 9 In this study, where the option for a patient-initiated in-person visit was unavailable during the pandemic-affected time period, patients who were 65 years or older were significantly more likely than younger patients (ages 18-44) to choose a video visit over a telephone visit. This finding is different from studies that examined the choice of video visits when the option for an in-person visit is available, [8] [9] [10] [11] [12] [13] including our prior study 14 which found that older patients generally preferred an in-person visit to either a video or a telephone visit before the pandemic and older patients were associated with lower video use during the pandemic. 9 In the current study, the preference for video visits among older patients may be because video visits can more closely approximate the visual interaction of an in-person visit. 12 Reimbursement differences between video and telephone visits, including from federal programs, may also encourage video visit use among elderly patients during the pandemic. Our distinct findings related to age and race/ethnicity during the pandemic may reflect the impact of differences in study settings, patient populations, geographic areas, and telemedicine implementation. Further, different health care settings likely also vary in their degree of outreach to promote and support telemedicine visits, and patients' technological readiness for telemedicine.

There are several limitations in this study. First, this study was conducted in an integrated health delivery system and the majority of visits were with the patient's own PCP, and the findings from this study setting may not directly generalize to other less-integrated telemedicine delivery settings or fee for service systems or other directto-consumer telehealth programs or different patient-initiated appointment workflows. Second, while KPNC members are representative of the Northern California population in terms of age, gender, and race/ethnicity, they tend to have higher education attainment, are less likely to have low/high extremes in income, and are more likely to have experience in health-related internet use. 15 Third, this study used electronic medical records and administrative data and did not include information on patients' perspective regarding personal preference and barriers to the type of telemedicine. Moreover, patients who use the portal for scheduling visits generally have more technology access and are more likely to be e-literate, 16 and the findings from this study do not represent patients who had no ability to access to the online portal. We do not have information on whether family members help to set up or participate in the telemedicine visit. Also, in deriving patient characteristics such as internet access and SES status, we did not have access to individual level measures and used general area characteristics based on patient's neighborhood. Finally, we used a broad categorization for the primary diseases based on ICD10 grouping. Both telephone and video telemedicine visits can provide patients with a convenient and safe way to access health care without the risk of being exposed to the virus during the pandemic. At a time when patient visits scheduled using the portal were limited to tele-phone or video, we found that the rate of video visits increased over time and patients' choice of video versus telephone appointment varied by patient characteristics. The difference in telemedicine choice by technology access suggests the persistence of a digital divide [8] [9] [10] [11] 14, 16, 17 may act as a barrier to video telemedicine. Moreover, it emphasizes the importance of maintaining a telephone telemedicine option, which may often be sufficient to address patients' health concerns. Pandemic-related shifts in visit availability and preferences may spur longer term changes in patient care-seeking preferences, but the degree to which these shifts persist remains to be seen. Further research is needed to examine the patients' perspective on preference and barriers for using telemedicine, and quality and clinical outcomes associated with telemedicine modality.
