The interval between visits is part of the treatment, not empty time waiting for the next encounter. The medication continues to work or to produce side effects. The behavioral changes the patient is trying continue or don't. The life events that affect the clinical picture happen. The clinician who plans the between-visit interval deliberately produces better care than the clinician who lets follow-up timing happen by default.
Match interval to clinical status. During medication initiation or destabilization, weekly to biweekly. During active treatment with response in progress, every 2-4 weeks. During maintenance with stability, monthly to quarterly. Highly stable maintenance, every 3-6 months. The wrong interval in either direction creates problems — too frequent costs patient time without benefit, too infrequent misses emerging issues.
Define triggers for earlier contact at every visit. What would prompt the patient to call before the next scheduled visit? Specific symptoms worsening (PHQ-9 climbing, return of insomnia, new suicidality). Side effects that aren't tolerable. Life events that destabilize. Medication-related concerns. The patient who knows what would prompt earlier contact has a relationship with the treatment, not just appointments.
Between-visit work happens. The patient is supposed to be taking medication, monitoring symptoms, engaging in behavioral changes if part of the plan, attending therapy if relevant. Make this explicit at the end of each visit: "Between now and next time, here's what we're both doing." The plan that's understood and shared gets followed; the plan that's vague drifts.
Document the next-step interval and rationale at the end of each note. Why this interval? What would change it? Sets the standard for the receiving clinician (if you go on leave or hand off) and supports your own next-visit planning.
Adjust as clinical status changes. The patient who was every 4 weeks during stable maintenance and is now in a depressive recurrence needs weekly visits for a while. The patient who has been every 2 weeks during active treatment and has stabilized for 3 months can move to every 4-6 weeks. Treat visit frequency as a clinical variable, not a fixed schedule.
