Partial Hospitalization, sometimes referred to as "PHP" or Day Treatment, is a type of drug rehabilitation center that works to deal with substance abuse disorders and psychological disorders which may possibly be co-occurring. In a PHP facility, the person in treatment takes part in a variety of treatment services and methods in the daytime and then leaves in the evening. This is done anywhere from five to seven days per week, depending on the significance of the drug or alcohol problem. Partial Hospitalization can be most effective for drug addicted individuals in Iowa City, Iowa who may not be able to pay for long-term inpatient rehab, or for treatment clients who are unable to be apart from their households for prolonged durations of time. While in Day Treatment, treatment clients participate in typical treatment services for drug and alcohol addiction problems while simultaneously addressing mental health issues which could keep them from staying sober after treatment is complete.
