What is the single most dominant force in U.S. health care delivery?

Rationale:

A. Physicians are paid at higher rates than private organizations: This statement does not accurately describe the staff model of managed care. Compensation rates may vary but are not necessarily higher than in private organizations.

B. The health maintenance organization (HMO) employs its own fixed-salary physicians: In the staff model, physicians and other healthcare providers are directly employed by the HMO and receive fixed salaries rather than fee-for-service payments.

C. Meets the nutritional and therapeutic requirements of the patients: This statement relates more to the provision of healthcare services rather than the employment model within managed care.

D. Registered nurses are sponsored by agency staffing companies: This statement does not pertain to the staff model of managed care; it describes a different aspect of healthcare staffing and employment.

A. Concurrent: Concurrent utilization review involves the ongoing monitoring of a patient's care and recovery while they are still receiving treatment. This type of review focuses on ensuring that the care provided is appropriate and that the patient is progressing as expected.

B. Preauthorization: Preauthorization involves obtaining approval from a health insurer before a service is provided to ensure it will be covered. It does not focus on monitoring a patient's recovery.

C. Retrospective: Retrospective review involves evaluating the care provided to a patient after the treatment has been completed. It looks at the appropriateness of care but does not monitor ongoing recovery.

D. Prospective: Prospective review involves evaluating the necessity of a treatment before it begins. It does not include ongoing monitoring of a patient's prognosis for recovery.
