Understanding Levels of Care

Mental health treatment exists on a continuum of care, ranging from weekly outpatient therapy to inpatient hospitalization. Partial Hospitalization Programs (PHP) and Intensive Outpatient Programs (IOP) fall between these extremes and are designed to provide structured, intensive support while allowing patients to return home each day.

What Is a Partial Hospitalization Program?

PHP is the higher level of the two programs, typically involving treatment five days per week for five to six hours per day. It is designed for individuals who require a high level of clinical support but do not need round-the-clock inpatient care. PHP often serves as a step-down from inpatient hospitalization or a step-up for individuals whose symptoms are not adequately managed in IOP.

What Is an Intensive Outpatient Program?

IOP provides a moderate level of structured support, typically three to five days per week for three hours per day. It is well-suited for individuals with significant mental health symptoms who are stable enough to function with greater independence. IOP allows more flexibility for work, school, and family obligations.

How to Choose the Right Level

The appropriate level of care is determined through a clinical assessment that considers symptom severity, safety, level of functioning, support systems, and treatment history. Your clinician will recommend the level of care most likely to support your recovery while matching your current clinical needs.

Transitioning Between Levels

It is common for individuals to move between levels of care as their treatment progresses. Someone may begin in PHP and step down to IOP as symptoms stabilize, then continue with weekly outpatient therapy. This stepped-care approach ensures ongoing support is matched to clinical need at every stage of recovery.
