Partial Hospitalization, sometimes referred to as "PHP" or Day Treatment, is a kind of drug and alcohol treatment center that works to deal with drug and alcohol addiction issues and psychological issues which may possibly be co-occurring. In a PHP center, the treatment client in rehabilitation takes part in a variety of rehabilitation activities and approaches in the daytime and then returns home in the night time. This is carried out anywhere from five to seven days per week, depending on the seriousness of the drug problem. Partial Hospitalization can be helpful for drug or alcohol addicted men and women in Foster who may not be able to pay for long-term inpatient treatment, or for treatment clients who are not able to be away from their home and work for extensive periods of time. While in Day Treatment, treatment clients participate in standard treatment services for alcohol or drug addiction issues while simultaneously addressing mental health disorders which could keep them from staying abstinent when rehabilitation is complete.
