Potential downsides of virtual group visits
SMAs and VSMAs may not work for every practice. Some small practices may not have enough patients to organize a group visit around a particular condition – even a common one like diabetes. In a presentation before the Society of General Internal Medicine, a physician from the Medical University of South Carolina, Charleston, warned that it may be difficult for a practice to fill diabetes group visits every year.
Additionally, some patients don’t want to talk about personal matters in a group. “They may not want to reveal certain things about themselves,” Dr. Mirsky said. “So I tell the group that if there is anything that anyone wants to talk about in private, I’m available.”
Another drawback of SMAs is that more experienced patients may have to slog through information they already know, which is a particular problem when patients can drop in and out of sessions. Dr. Mirsky noted that “what often ends up happening is that the experienced participant helps the newcomer.”
Finally, confidentially is a big concern in a group session. “In a one-on-one visit, you can go into details about the patient’s health, and even bring up an entry in the chart,” Dr. Wheeler said. “But in a group visit, you can’t raise any personal details about a patient unless the patient brings it up first.”
SMA patients sign confidentiality agreements in which they agree not to talk about other patients outside the session. Ensuring confidentiality becomes more complicated in virtual group visits, because someone located in the room near a participant could overhear the conversation. For this reason, patients in V-SMAs are advised to use headphones or, at a minimum, close the door to the room they are in.
To address privacy concerns, Zoom encrypts its data, but some privacy breeches have been reported, and a U.S. senator has been looking into Zoom’s privacy vulnerabilities.
Transferring groups to virtual groups
It took the COVID-19 crisis for most doctors to take up virtual SMAs. Dr. Sumego said that the Cleveland Clinic started virtual SMAs more than a year ago, but most other groups operating SMAs were apparently not providing them virtually before COVID-19 started.
Dr. Dysinger said he tried virtual SMAs in 2017 but dropped them because the technology – using Zoom – was challenging at the time, and his staff and most patients were resistant. “Only three to five people were attending the virtual sessions, and the meetings took place in the evening, which was hard on the staff.”
“When COVID-19 first appeared, our initial response was to try to keep the in-person group and add social distancing to it, but that wasn’t workable, so very quickly we shifted to Zoom meetings,” Dr. Dysinger said. “We had experience with Zoom already, and the Zoom technology had improved and was easier to use. COVID-19 forced it all forward.”
Are V-SMAs effective? While there have been many studies showing the effectiveness of in-person SMAs, there have been very few on V-SMAs. One 2018 study of obesity patients found that those attending in-person SMAs lost somewhat more weight than those in V-SMAs.
As with telemedicine, some patients have trouble with the technology of V-SMAs. Dr. Dysinger said 5%-10% of his SMA patients don’t make the switch over to V-SMAs – mainly because of problems in adapting to the technology – but the rest are happy. “We’re averaging 10 people per meeting, and as many as 20.”
