Partial Hospitalization, sometimes referred to as "PHP" or Day Treatment, is a form of drug rehabilitation center that is meant to deal with substance abuse disorders and mental health issues which may possibly be co-occurring. In a PHP center, the person in rehabilitation partakes in various rehab activities and approaches in the daytime and then leaves in the evening time. This is done several days per week, all dependent on the seriousness of the drug problem. Partial Hospitalization can be most effective for drug addicted individuals in Tunnel who who may be unable to pay for long-term inpatient rehab, or for treatment clients who are not able to be apart from their households for extended lengths of time. While in Day Treatment, people take part in standard treatment services for addiction problems while at the same time addressing mental health problems which could keep them from staying sober when rehabilitation is complete.
