Partial Hospitalization, sometimes called "PHP" or Day Treatment, is a type of drug and alcohol rehab facility which is meant to deal with drug addiction disorders and mental health problems which may possibly be co-occurring. In a PHP center, the person in rehab takes part in a variety of treatment activities and strategies in the day and then returns home in the evening. This is done anywhere from five to seven days a week, depending on the significance of the drug or alcohol problem. Partial Hospitalization can be most effective for addicted people in Charlestown, Massachusetts who are unable to cover the costs of long-term inpatient rehab, or who are not able to be apart from their households for extended lengths of time. While in Day Treatment, treatment clients take part in typical treatment services for drug and alcohol addiction problems while also addressing psychological issues which could keep them from staying abstinent after rehabilitation is done.
