Partial Hospitalization, also known as "PHP" or Day Treatment, is a kind of drug rehabilitation facility that works to treat drug and alcohol addiction disorders and mental health issues which may possibly be co-occurring. In a PHP program, the person in rehabilitation participates in a variety of treatment activities and techniques in the day and then leaves in the night time. This is done anywhere from five to seven days per week, depending on the seriousness of the drug problem. Partial Hospitalization can be most effective for drug or alcohol addicted men and women in Pekin who may not be able to pay for long-term inpatient rehab, or for those who are unable to be away from their home and work for prolonged durations of time. While in Day Treatment, people participate in typical treatment services for addiction problems while also dealing with mental health issues which may deter them from staying abstinent after rehabilitation is complete.
