Partial Hospitalization, also known as "PHP" or Day Treatment, is a type of alcohol and drug rehabilitation program which is meant to deal with drug and alcohol addiction issues and mental health disorders which might be co-occurring. In a PHP facility, the treatment client in rehab takes part in a number of treatment activities and methods in the daytime and then leaves in the night time. This is done anywhere from five to seven days a week, depending on the seriousness of the drug problem. Partial Hospitalization can be most effective for addicted men and women in Valhalla, New York who may not be able to cover the costs of long-term inpatient rehab, or for treatment clients who are unable to be apart from their home and work for prolonged durations of time. While in Day Treatment, individuals participate in typical treatment services for addiction problems while also addressing mental health issues which could keep them from remaining abstinent after rehab is done.
