Health Care Utilization With Telemedicine and In-Person Visits in Pediatric Primary Care

Telemedicine is an increasingly used yet understudied vehicle to deliver pediatric primary care. Evidence detailing downstream health care utilization after telemedicine visits is needed.

To compare pediatric primary care conducted via telemedicine (video or telephone) with in-person office visits with regard to physician medication prescribing and imaging and laboratory ordering and downstream follow-up office visits, emergency department (ED) visits, and hospitalizations.

This cohort study included all patients younger than 18 years who had scheduled primary care appointments with a pediatrician from January 1 to December 31, 2022, in the Kaiser Permanente Northern California health system, a large integrated health care delivery system offering in-person office visits, video visits, or telephone visits for pediatric primary care.

Pediatric primary care in-person visit, telephone visit, or video visit.

Rates of physician medication prescribing and imaging and laboratory ordering during an index telemedicine or office visit and rates of in-person office visits, ED visits, and hospitalizations within 7 days after the visit, adjusted for patient and clinical characteristics.

Of 782 596 total appointments (51.1% male) among 438 638 patients, telemedicine was used for 332 153 visits (42.4%). After adjustment, there was more medication prescribing for in-person visits (39.8%) compared with video visits (29.5%; adjusted difference, -10.3%; 95% CI, -10.6% to -10.0%) or telephone visits (27.3%; adjusted difference, -12.5%; 95% CI, -12.5% to -12.7%). There was also more laboratory ordering for in-person visits (24.6%) compared with video visits (7.8%; adjusted difference, -16.8%; 95% CI, -17.0% to -16.6%) or telephone visits (8.5%; adjusted difference, -16.2%; 95% CI, -16.3% to -16.0%). There was more imaging ordering for in-person visits (8.5%) compared with video visits (4.0%; adjusted difference, -4.5%; 95% CI, -4.6% to -4.4%) and telephone visits (3.5%; adjusted difference, -5.0%; 95% CI, -5.1% to -4.9%). After adjustment, fewer in-person follow up visits occurred for index visits that were in-person (4.3%) compared with video (14.4%; adjusted difference, 10.1%; 95% CI, 9.9%-10.3%) or telephone (15.1%; adjusted difference, 10.8%; 95% CI, 10.7%-11.0%) visits. The rate of ED visits following an in-person visit was slightly lower (1.75%) compared with after video visits (2.04%; adjusted difference, 0.29%; 95% CI, 0.21%-0.38%) or telephone visits (2.00%; adjusted difference, 0.25%; 95% CI, 0.18%-0.33%). There was no statistically significant difference in the 7-day rate of hospitalizations.

In this cohort study, telephone and video visits for pediatric primary care were associated with less prescribing and ordering than in-person visits. Telemedicine visits were associated with modestly higher rates of subsequent in-person visits and slightly higher rates of ED visits, and there was no difference in hospitalizations. Telemedicine appears to be a useful vehicle for health care delivery in the pediatric population, although it is not a universal substitute for in-person visits.
