Partial Hospitalization, sometimes referred to as "PHP" or Day Treatment, is a form of alcohol and drug rehab program that works to handle substance abuse issues and psychological disorders which might be co-occurring. In a PHP program, the person in rehab participates in a number of rehab activities and approaches in the day and then leaves in the night time. This is carried out several days per week, depending on the significance of the drug problem. Partial Hospitalization can be helpful for drug addicted persons in Philadelphia, Pennsylvania who are unable to cover the costs of long-term inpatient rehab, or who are unable to be away from their home and work for extended lengths of time. While in Day Treatment, people take part in standard treatment services for addiction problems while simultaneously dealing with mental health issues which may deter them from staying abstinent after rehab is done.
