How often do you repeat a formal suicide risk screen at follow-up visits?

Patient safety and suicide, in my practice, is always my number one priority. However, that does not translate into plastering every patient encounter with a formal suicide risk assessment. Once I come to know my patient's history, stability, and life situation, for most ongoing patients in my outpatient psychiatry practice, suicide risk is not a concern. It's just plain fatuous, and alienating to the maintenance of doctor-patient rapport, to force every patient to complete a suicide risk checkl...

This really depends on the patient: whether they have had any history of suicidality, whether perhaps their depression is sometimes accompanied by suicidal, even passive suicidal thoughts. That would, in general, be a more frequent look-see, perhaps not a formal screen, but just asking a question as part of a routine follow-up, going over any neurovegetative, depressive symptoms, etc.
