How To Choose Between PHP vs IOP For Substance Use Addiction?
IOP or PHP? Confused about which to choose? Each level of support addresses different levels of severity, condition, and treatment goal. Here are the things to consider:

Intensive outpatient program (IOP) has a flexible schedule, and it offers:
- More flexibility in time
- 2-4 hours per session, 3-5 times per week

Intensive outpatient care may be effective:

What is the Continuum of Care in Addiction Treatment?
In a continuum of care, patients “step down” to less-intensive levels of care as they recover 2. To break the cycle of addiction, the licensed clinical addiction specialist examines the individual to get a better idea of the condition and decides:
- Medical Detoxification to cleanse the system from harmful toxins/substances
- Inpatient Treatment or Residential Care for intensive support to overcome severe addiction symptoms and withdrawals
- PHP (Partial Hospitalization Program) for patients who require intensive daytime treatment and therapy
- IOP (Intensive Outpatient Program) for structured and part-time addiction support
- Transitional Living or Aftercare for post-treatment care to prevent relapse
How Mental Health Conditions Influence Your Addiction Treatment Choice?
Addiction to drugs or alcohol is considered a mental illness. This is because substance use interferes with daily life activities and responsibilities. 7.9 million people in the U.S. had a co-occurring disorder 6.
Struggling with two conditions at the same time is known as “comorbidity”. Having a SUD and a mental health illness at the same time complicates the condition, and it needs a more intensive level of care.
Here’s how it influences addiction treatment choice:
The Partial Hospitalization Program (PHP) is preferable to individuals who need:
- Daily psychiatric oversight for mental health illness
- Structured care for addiction
Intensive Outpatient Program (IOP) is suitable for individuals who are:
- Stable mentally, but still needs support for a psychiatric illness
- Already on the journey of recovery
IOP Vs PHP: Which Treatment Is Best For You? The Final Verdict
The therapist diagnoses the condition and places the patient in a setting that will address the severity:
- Partial hospitalization program/partial care is for high levels of addiction
- An intensive outpatient program is for moderate levels of addiction
