"IOP" stands for "Intensive Outpatient Program." Mental health treatment can take the form of inpatient or outpatient. Inpatient care is done at a mental health facility. Those suffering from severe addictions or depression are examples of patients who might need to receive constant supervision. For many others living at home while participating in outpatient care (support groups, telehealth options, therapist visits, etc.) allows for patients to receive treatment while engaging in daily home, work and community life. An Intensive Outpatient Program (IOP) offers a plan for those who do not require residential (inpatient) care, but need more structured treatment than a basic outpatient program offers. IOP patients can maintain daily routines while participating in a holistic treatment plan.
