Do care manager phone calls between visits help patients with depression?
Yes. In a 600-patient randomized trial, adding telephone care management to usual primary care raised the share of patients who rated their depression much improved, from 55% to 66%, and satisfaction from 29% to 47%. Pairing those calls with brief phone therapy helped more, reaching 80% much improved.
What does this mean for your clinic?
Start with what the calls actually were, because the plain version is easy to miss. Telephone care management here was not therapy. It was a care manager reaching out between visits: at least 3 calls, a note back to the treating physician, and help coordinating the plan. The question for a practice is whether that low-cost outreach, on its own, changes how patients do.
The honest answer from this trial is that it helps, but modestly. Patients who got the calls were more likely to say their depression was much improved, 66% versus 55%, and far more likely to be very satisfied with their care, 47% versus 29%. Those are real gains in engagement and experience. But on the average symptom score, the trial could not show a clear difference from the calls alone. So care management reached people and kept them in care, yet by itself it did not move the main clinical number.
What did move it was adding structured work to the calls. The arm that paired care management with an 8-session phone therapy program had lower depression scores and the highest rate of feeling much improved, 80%. Read together, the two arms tell a clear story for a clinic: outreach gets patients engaged and satisfied, and giving them something to do on those calls is what turns engagement into symptom change.
The participation numbers are worth your attention too. 97% and 93% of patients took part in the phone programs. For a practice that loses people between visits, that is the headline. A phone call met patients where they were, and almost all of them stayed in contact. Outreach that patients actually accept is the first problem solved, before any clinical effect is possible.
Now the limits, plainly. This was one trial run in a single integrated health system in Seattle, in group-model clinics, with patients who were just starting antidepressant treatment and were not already in psychotherapy. Your caseload may look different, and your usual care is your own. The trial also predates many of today's tools. Treat it as strong evidence that between-visit outreach keeps patients engaged, and as a reminder that the calls work best when they carry real clinical content and a loop back to the prescriber.
The takeaway
- Between-visit calls raised how improved and how satisfied patients felt, with very high participation, so outreach is an accessible way to hold onto people.
- Calls alone did not clearly move symptom scores. Pairing outreach with structured therapy did.
- Decide who makes the calls, what clinical work happens on them, and how the result gets back to the prescribing clinician.
This is the work Asendar™ was built for: making the work between sessions visible to your team, so a care manager can see who is engaged and who is drifting before the next visit, and each visit opens with context from the week instead of a cold start. See how it fits a collaborative care clinic.
