Partial Hospitalization, sometimes called "PHP" or Day Treatment, is a kind of alcohol and drug treatment program which is meant to treat substance abuse problems and mental health issues which may possibly be co-occurring. In a PHP program, the person in treatment participates in a number of rehab services and methods in the day and then returns home in the evening. This is carried out anywhere from five to seven days a week, depending on the seriousness of the drug or alcohol problem. Partial Hospitalization can be most effective for drug addicted persons in Roxbury who may not be able to cover the costs of long-term inpatient care, or for those who are unable to be away from their families for extended durations of time. While in Day Treatment, treatment clients participate in standard treatment services for drug and alcohol addiction issues while also dealing with mental health disorders which could keep them from remaining sober once rehabilitation is done.
