Partial Hospitalization, sometimes called "PHP" or Day Treatment, is a kind of drug and alcohol treatment facility that works to handle substance abuse issues and mental health issues which may possibly be co-occurring. In a PHP center, the treatment client in rehabilitation participates in various rehab services and methods in the daytime and then leaves in the night time. This is carried out anywhere from five to seven days per week, depending on the seriousness of the drug or alcohol problem. Partial Hospitalization can be most effective for drug or alcohol addicted persons in York, Pennsylvania who who may be unable to pay for long-term inpatient treatment, or who are not able to be away from their families for extensive periods of time. While in Day Treatment, people participate in standard treatment services for drug and alcohol addiction issues while at the same time addressing mental health problems which may deter them from remaining abstinent when rehabilitation is done.
