Intensive Outpatient Programme
Also written as: IOP — Intensive Outpatient Programme
A structured psychiatric treatment programme delivering therapeutic services for approximately nine or more hours per week in a non-residential outpatient setting.
Full Definition
An Intensive Outpatient Programme (IOP) represents a level of psychiatric care that is less intensive than a partial hospitalisation programme but more structured than standard outpatient therapy. IOPs typically involve three to five sessions per week, each lasting two to three hours, and include group psychotherapy, psychoeducation, and medication monitoring. IOPs are commonly used for step-down from partial hospitalisation or as an early intervention to prevent inpatient admission. The abbreviation 'IOP' is consistent across most US payer and regulatory documents; editors should ensure it is not conflated with 'IP' (inpatient) in abbreviated clinical notes.
Usage
Usage note: Do not abbreviate as 'OP' or 'OPT'. Ensure 'IOP' is defined on first use, particularly in documents that also reference 'IP' for inpatient.
