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.
Communist Party of the Soviet Union
The primary party organization (PPO) was the lowest level in the CPSU hierarchy. PPOs were organized cells consisting of three or more members. A PPO could exist anywhere; for example, in a factory or a student dormitory. They functioned as the party's "eyes and ears" at the lowest level and were used to mobilize support for party policies. All CPSU members had to be a member of a local PPO. The size of a PPO varied from three people to several hundreds, depending upon its setting. In a large enterprise, a PPO usually had several hundred members. In such cases, the PPO was divided into bureaus based upon production-units. Each PPO was led by an executive committee and an executive committee secretary. Each executive committee is responsible for the PPO executive committee and its secretary. In small PPOs, members met periodically to mainly discuss party policies, ideology or practical matters. In such a case, the PPO secretary was responsible for collecting party dues, reporting to higher organs and maintaining the party records. A secretary could be elected democratically through a secret ballot, but that was not often the case; in 1979, only 88 out of the over 400,000 PPOs were elected in this fashion. The remainder were chosen by a higher party organ and ratified by the general meetings of the PPO. The PPO general meeting was responsible for electing delegates to the party conference at either the district- or town-level, depending on where the PPO was located.
