Why the evaluation here takes two sessions
In much of American outpatient psychiatry, a new patient evaluation lasts thirty minutes, and sometimes less. In that window a clinician is expected to take a psychiatric history, screen for medical causes, assess safety, reach a diagnosis, explain it, and start treatment. It cannot be done well. Everyone in the field knows it cannot be done well. The visit length is set by billing economics, not by what the task requires.
The first visit is where the most consequential decisions of your entire treatment get made. Diagnoses assigned in that first hour tend to follow people for years, copied forward from note to note. A first prescription anchors everything that comes after it: if it fails, the next step is usually framed as an adjustment to that choice rather than a fresh look. Errors made at the beginning compound; that is precisely why the beginning deserves the most time, and in most systems gets the least.
A rushed evaluation does not produce a smaller amount of understanding. It produces a confident-sounding guess.
Here is some of what a thirty-minute evaluation routinely has no room for. The medical conditions and medications that mimic psychiatric illness. The sleep history, which reorganizes the differential diagnosis more often than almost anything else. The timeline of how symptoms actually emerged over a life, which frequently distinguishes conditions that look identical in a snapshot. The question of what has genuinely been tried before, at what dose, for how long, since "I tried that and it did not work" often turns out to mean two weeks at a starting dose. And the person's own theory of what is wrong, which is sometimes correct and always informative.
This practice runs the evaluation as two 60-minute sessions on separate days, and the space between them is not scheduling convenience. It is method. A single interview captures one day of your life, and psychiatry has a long history of mistaking a bad week for a disorder and a good day for recovery. Two samples taken days apart begin to separate state from trait. The gap also generates data no first meeting can: how you slept afterward, what surfaced on the drive home, which questions you kept arguing with. And it protects against the oldest error in medicine, anchoring, because the second session exists partly to attack the first session's hypothesis before it hardens into your chart.
Two hours also makes an evaluation possible rather than merely fast. There is room to check the streams a checklist skips: the biological context, the developmental arc, the relationships and pressures symptoms live inside, the things that give your life meaning and where that meaning has thinned out. A formulation built from those streams is specific enough to be tested, and a plan built on it can be explained in plain language, including what we expect to happen and what we will do if it does not.
There is also a quieter reason. Being thoroughly listened to, once, changes what patients expect from their care afterward. People who have been understood ask better questions, report side effects sooner, and participate in decisions instead of receiving them. That is not a soft benefit. It is the difference between treatment that adapts and treatment that drifts.
So the evaluation here is two 60-minute sessions, and it will stay that way. It is the least efficient part of this practice by the numbers, and the most valuable part by every measure that matters.
