Partial Hospitalization, also known as "PHP" or Day Treatment, is a type of drug treatment center that works to handle drug addiction issues and mental health disorders which may be co-occurring. In a PHP program, the individual in treatment takes part in a variety of rehabilitation activities and approaches in the daytime and then leaves in the evening time. This is done anywhere from five to seven days per week, all dependent on the severity of the drug or alcohol problem. Partial Hospitalization can be helpful for drug or alcohol addicted people in Chester who are unable to cover the costs of long-term inpatient care, or for treatment clients who are unable to be away from their home for prolonged periods of time. While in Day Treatment, individuals participate in traditional treatment services for alcohol or drug addiction issues while simultaneously dealing with psychological disorders which could keep them from staying abstinent after rehab is complete.
