Preferred provider organization
In health insurance in the United States, a preferred provider organization (PPO), sometimes referred to as a participating provider organization or preferred provider option, is a managed care organization of medical doctors, hospitals, and other health care providers who have agreed with an insurer or a third-party administrator to provide health care at reduced rates to the insurer's or administrator's clients.

Use of BPO pantomimes, instead of the IO pantomimes dominant in non-apraxic patients (i.e. BPO errors), is one of the diagnostic error patterns in apraxia. Though BPO errors seem to be inconsistent in their efficacy for diagnosing apraxia: many studies have shown BPO errors being distinctly associated with the apraxic symptomatology; while many have shown they are not. However, it has been asserted that these apparently contradicting results may be due to a lack of control for confounding factors. For example, BPO errors are differentially affected by age and educational level in normal subjects; older, healthy people (tested group average 69 years old) and healthy adults with lower amount of education (tested group with average 7.2 years of formal education) make significantly more BPO errors than the average adult population.
