EHR reminders boost well-child visits, vax rates



Reminder messages sent through electronic health records (EHRs) to patient portals increased rates of scheduling and completion of well-child visits for those overdue for well care, as well as vaccination rates, according to data published today in JAMA Network Open.

Anne E. Berset, BA, with general and community pediatrics at Cincinnati Children’s Hospital, led a randomized clinical trial conducted at three academic primary care practices from July 30 to Oct. 4, 2021.

The practices serve a mostly non-Hispanic Black, low-income population and provide more than 60,000 visits a year to 30,000 patients.

The study population included 945 patients, 62.4% of them non-Hispanic Black and 807 (85.4%) covered by public insurance.

Standard message and tailored message compared

The study population was randomized to get either a standard reminder message, a tailored message, or no message (control group).

The standard messages referenced the patient’s first name and reminded parents their child was due for a well-child visit, and asked them to schedule it using the portal or by calling the number provided.

The tailored message added the date of the last well-child check-up “to address distortions of time perception experienced during the pandemic,” the authors write.

The primary outcome was whether the well-child visit was completed within 8 weeks. Other outcomes included whether a well-child visit was scheduled within 2 weeks of the first reminder message and whether the patient received a COVID-19 vaccine within 8 weeks of the reminder.

Reminders outperform control group

There was a significant increase in scheduling and completion of appointments after parents received the standard and tailored messages compared with controls.

The results with the COVID reminders were particularly striking. While only 3.7% of the eligible patients got a vaccine when they got no message, 17.3% got the vaccine in that time frame when they got the standard message. Interestingly, only 2.7% received the shot after the tailored message.

J. Howard Smart, MD, with Sharp HealthCare in San Diego, told this publication he was not surprised that a patient portal reminder would increase the rate of scheduling overdue well-child visits. “Parents may indeed have lost track of when their children need to have check-ups” during the pandemic, he said.

Reminders without tailored information more effective

He said he was surprised, just as the investigators were, that the reminders without the tailored information seemed to be more effective for some outcomes.

The authors explained that a focus group found “that families with patient portal accounts prefer straightforward, brief, and user-friendly messages.”

That may help explain why the standard message outperformed the tailored message, the authors write.

“Families may have been distracted by the additional information related to the child’s age and date of last WCC [well-child check-up] in the tailored message,” they write.

Dr. Smart said, “Their discussion of why this might be the case sounds reasonable. Simple, short messages may be better received.”

“Evidence like this should stimulate portal software vendors to make this kind of outgoing messaging easy to set up for providers,” he said.
