Partial Hospitalization Programs

Partial Hospitalization Program Definition

A partial hospitalization program (PHP) is a structured mental health program and type of addiction treatment where clients participate in activities during the day and return home at night. These programs are available at inpatient or residential treatment facilities.

PHPs provide structured, comprehensive care while still allowing people to live their lives outside of treatment.

They are sometimes called intensive outpatient programs (IOPs) or day programs because they don't require an overnight stay.

Partial hospital programs are for people diagnosed with a:4

Someone in a partial hospitalization program is medically monitored during treatment. They participate in a variety of evidence-based therapies.

While the name can seem intimidating, a partial hospitalization program is simply a special outpatient treatment program. It's for people who need a higher level of behavioral health care than standard outpatient programs can provide.

What Happens in a Partial Hospitalization Program?

In a PHP, the following depends on the needs of each client:

  • Type of treatment
  • Length of treatment
  • Intensity of treatments
  • The medical treatment plan used

Other factors also determine a patient’s treatment plan:

  • The severity of addiction
  • Mental health treatment needs
  • Medical insurance coverage


The most common services that partial hospitalization programs offer include:

  • Behavioral therapies: Individual counseling (psychotherapy), group therapy, cognitive-behavioral therapy (CBT), dialectical behavior therapy (DBT), contingency management, and mental health counseling.
  • Case management: Most programs will assign a case manager to coordinate a person's treatment program.
  • Relapse prevention: Counselors or therapists help come up with a relapse prevention plan. This plan identifies triggers, lists warning signs of a potential relapse, and details alternative courses of action.
  • Holistic therapies: Yoga, art therapy, animal therapy, and other holistic treatments can be helpful for recovery.
  • Fitness and nutrition: A person's body undergoes significant changes during detox and recovery. Nutritionists and fitness coaches can help people adjust.
  • Medication management: Certain people may already be prescribed medication or need medication-assisted therapy from a licensed psychiatry provider.
  • Vocational skill groups: Some facilities offer short-term skill development programs to help people prepare for the job force.
  • Support groups: 12-step programs, peer counseling, and nonprofit organizations.
  • Aftercare planning: This ensures that each person is set up for success. If necessary, they can continue treatment after completing the program.


While the treatments and therapies may vary, there are five stages to the program that everyone can expect:

1. Evaluation

The first stage is evaluation. Patients undergo:

  • An interview
  • Medical examination
  • Urine test

These results provide the foundation of the treatment plan.

2. Detoxification

The next step is detox. The body must adjust to functioning without drugs or alcohol.

This can be a challenging stage. Withdrawal symptoms are also the worst during this time. Medical care and monitoring are usually necessary.

3. Psychological and Medical Treatment

After detox, therapy and other medical treatments begin.

They focus on the following:

  • Learning skills and techniques to prevent relapse
  • Discovering valuable resources
  • Building a community of people committed to helping each other live healthy, sober lives

4. Transition

Once the knowledge and tools are established, the intensity of treatments will be scaled down.

The number of days or hours spent at the facility will decrease to focus on transitioning to a sober life.

5. Maintenance

Aftercare is an essential part of a partial hospitalization program.

Many groups help provide:

  • Consistent maintenance
  • Continuous skill-building and practicing
  • Support and care throughout a person's sober life

These support groups include:

  • Alcoholics Anonymous (AA)
  • SMART Recovery
  • Other peer support systems

How Long is a Partial Hospitalization Program?

The length of a partial hospitalization program depends entirely on the patient’s needs. It is an intensive, short-term treatment method that could last a couple of weeks to several months.

They are designed to help you improve enough to move to an outpatient treatment program.

Partial Hospitalization Programs vs. Inpatient and Residential Programs

During inpatient and residential treatment programs, 100 percent of the program takes place at the facility.

Patients eat, sleep, and undergo all treatment at the residency for the duration of their program. The residency duration for both programs is typically 30, 60, or 90 days.

During partial hospitalization programs, all of the treatment services take place at the facility. However, the patient returns home to sleep.

Some programs provide food and transportation. These services vary depending on the agenda.

Often, if a patient has completed an inpatient treatment program, but still needs intensive care before fully integrating into society, a partial hospitalization program may be the next step.

  • Location
  • Services and amenities
  • Length of stay
  • Level of care
