Partial Hospitalization, sometimes called "PHP" or Day Treatment, is a type of drug rehabilitation program which works to deal with substance abuse disorders and mental health issues which may possibly be co-occurring. In a PHP center, the person in treatment partakes in a number of treatment services and strategies in the day and then leaves in the evening time. This is carried out anywhere from five to seven days per week, all dependent on the severity of the drug problem. Partial Hospitalization can be most effective for addicted people in Vienna who who may be unable to pay for long-term inpatient rehab, or for those who are unable to be away from their home and work for extensive lengths of time. While in Day Treatment, individuals take part in standard counseling and therapy for addiction issues while at the same time overcoming mental health issues which may deter them from remaining abstinent after treatment is complete.
