Every year, hundreds of thousands of Americans die as result of substance misuse. Luckily, there are thousands of treatment programs out there that can help you or your loved one regain sobriety. One of the most effective forms of treatment for substance use disorders is what is known as intensive outpatient programs (IOPs).

What Is an Intensive Outpatient Program (IOP)?

There are two major forms of drug and alcohol rehab: inpatient and outpatient rehab. Inpatient rehab requires patients to live at a treatment facility where they attend treatment and therapies. Inpatient rehab is generally considerably more expensive than outpatient rehab, and also makes it difficult, if not impossible, for patients to maintain their personal, legal, financial, and professional responsibilities. However, inpatient rehab is widely believed to provide the greatest likelihood of successfully achieving and maintaining sobriety.

Outpatient rehab is typically considerably less expensive than inpatient rehab, and it allows patients to continue to fulfill their daily obligations while still getting treatment. While outpatient rehab is generally considered to be less effective than inpatient rehab, there are many outpatient programs that are every effective at helping patients regain their sobriety.

One of the most effective forms of outpatient rehab are intensive outpatient programs (IOPs). Intensive outpatient programs (IOPs) , also sometimes referred to as intensive outpatient treatment programs (IOTPs), are structured, non-residential addiction treatment programs. IOPs are designed to treat mental health and substance use disorders that do not (or no longer) require medically supervised detox, medical monitoring, around-the-clock care, or hospitalization.

“IOP is a good option for those who are struggling with sobriety after detox and/or those with family or job obligations,” says psychiatric mental health nurse practitioner (PMHNP) Valerie Puffenberger.

IOP programs do not include detox. However, IOPs very frequently accept patients who have just completed detox and are looking for an alternative to inpatient rehab. Many patients also attend IOPs as a step-down level of care after they have completed an inpatient program.

How Does an IOP Work?

Most IOP programs require patients to meet several days a week for several hours at a time. While the exact schedule will vary from one IOP program to the next, most require patients to attend between six and thirty hours per week of programming. IOP programs have a strict schedule and structure that patients must follow, although most programs can be set up in a somewhat flexible manner so that patients can continue to work, care for family, attend class, or fulfill other responsibilities.

Conveniently, many IOP programs supplement in-person treatment with check-ins online or over the phone.

IOP programs treat their patients in a number of ways; however, therapy and life skills/relapse prevention training are generally the largest and most important components. Although individual therapy sessions are frequently included as part of an IOP program, group therapy makes up the bulk of therapeutic sessions in most IOPs.

The goal of IOP therapy and skills training sessions is to help patients uncover the underlying causes of their addictions, as well as their triggers. IOP helps patients learn more about themselves and teaches them how they can improve their lives. IOP is designed to provide patients with the knowledge and skills they need to prevent relapse and maintain their sobriety.

Many IOPs require drug and alcohol testing, but other forms of medical supervision or monitoring are absent from the vast majority of IOPs. However, IOPs do provide some level of mental health monitoring and help patients stay accountable.

Intensive Outpatient Program (IOP) vs Partial Hospitalization Program (PHP)

Another form of outpatient rehab is what is known as a partial hospitalization program, or PHP. Partial hospitalization programs share several similarities with IOP programs, but there are many differences. In fact, many treatment professionals consider partial hospitalization programs to be more like inpatient rehab programs than intensive outpatient programs.

The major difference between partial hospitalization programs and IOPs is that PHPs are more intensive. Partial hospitalization programs require more frequent and longer treatment sessions than IOPs. PHPs typically require patients to attend five days of sessions a week, for between four to eight hours a day, although this varies by patient.

Although PHPs do not provide the level of medical monitoring that is found with inpatient rehab, PHPs often do provide more medical monitoring than IOPs. This means that partial hospitalization programs are often better choices for those who are still in need of detox vs IOPs. PHPs are also considered a better choice for patients who feel less stable of who are less secure of their ability to prevent relapse.

Benefits of IOPs

There are many potential benefits of enrolling in an IOP program, including:

It can serve as a transitional step between inpatient rehab or PHP and “the real world,” outside of treatment.
Family involvement in treatment is more possible than is the case with other treatment options.
Flexible scheduling allows patients to receive treatment while maintaining their responsibilities.
Less expensive than many other forms of treatment.
Maintains normalcy in the patient’s life, which reduces the stress caused by ending treatment.
IOPs provide relapse prevention skills that help patients maintain their sobriety.
Gain access to peer support that helps prevent relapse.
Structured in a way that trains patients to lead a more healthy and productive life.

Intensive Outpatient Program Success Rates

Studies have consistently shown that IOP is effective at treating substance use and mental health disorders and that IOP patients have a much higher likelihood of achieving lasting sobriety than those who attempt sobriety without any treatment.

However, the potential for any individual to achieve sobriety via an IOP program depends on many factors, including:

What substances are the focus of the use disorder or disorders
The presence of co-occurring mental health conditions and substance use disorders
Age, gender, weight, and genetics
The motivation of the patient to achieve sobriety
The patient’s support network, both within and outside of the IOP
The skill, training, and experience of the IOP’s staff
The length and severity of any substance use or mental health conditions

Finding an IOP that Works for You

There are thousands of IOP programs throughout the country, meaning you will be able to find one that works for your needs and goals.

“When considering an IOP it is important to consider services that are offered such as cognitive behavioral therapy, family education and counseling, medication management, trauma-focused therapy, and wellness education,” says Puffenberger.

Additionally, you’ll want to keep the following in mind as you compare IOPs:

Geographical location and convenience of the IOP program

The cost of the IOP and what payment options are available to you
Whether or not the IOP program takes your insurance plan
The reputation of the IOP program
The accreditation and experience of the IOP’s staff
The scheduling options that the IOP provides
What treatments and therapies the IOP provides
Whether or not the IOP has programs specific to your needs (e.g., a veteran’s program or an opioid program)

Local IOPs

The vast majority of patients choose to attend local IOPs because it minimally impacts their daily responsibilities and routines.

However, in some cases, an IOP that is not close to a patient’s residence may be advisable, as distance may enable them to escape negative or triggering people, places, and things.

Online IOP Programs

Studies have shown that online IOP programs can be an effective form of treatment, especially if patients are dedicated and active in their attendance and participation. Online IOP programs provide even greater flexibility than traditional IOPs and are even less disruptive to patients’ lives.

Intense Outpatient Program FAQs

How is an IOP program different from a partial hospitalization program (PHP)?

In general, IOP programs are less intensive than partial hospitalization programs (PHPs). IOP programs typically require patients to attend significantly fewer hours of treatment a week.

Partial hospitalization programs (PHPs) are considered more rigorous than IOP programs. They also provide greater possibilities for medical and clinical monitoring. Patients who have a firmer grip and/or more time in sobriety are generally better suited to an IOP program vs a partial hospitalization program.

What are the benefits of an online IOP program?

There are many benefits to online IOPs. Some of the most important include:

Scheduling flexibility – perhaps more than any other treatment option
Cost effectiveness – some of the least expensive treatment options available
The ability to choose the right program for each patient regardless of distance

How do I find an IOP program near me?

There are many ways to find an IOP program near you. One of the most reliable is to contact local religious, charitable, governmental, and health care organizations. Another is to conduct an internet search for terms like “IOP near me”.

Can an IOP program help with eating disorders?

Some IOP programs will be able to provide help with eating disorders, and others will not. It will entirely depend on the program. Eating disorders often require special care, especially if they are severe and long-lasting, so make sure to ask any IOP you’re considering if they specialize in that area.

Also, please be aware that some severe eating disorders require inpatient treatment. If you want to know whether a specific IOP program can provide help with eating disorders, and what help they can provide, you should contact them directly.
