Due to the priority given to profit, HMOs may restrict the duration of patients' visits to the doctor and may deny the patient the treatment that the doctor has recommended.
2. HMO profit-oriented practices can be injurious to patient health as well as a waste of the doctor's time. Patients on complicated drug regimens may not adjust well to the replacement of one of their prescriptions by a cheaper alternative. In the case of maladjustment, the patient must make numerous extra visits to the physician to identify the problem and allow supervision of his recovery. In addition, the HMOs pressure doctors into releasing patients from hospital before they are ready.
3. The per capita payment method encourages doctors not to give patients the best quality care. If doctors receive the same payment regardless of patient health care needs, it is in their financial interest to have patients who require little care, and to spend as little time as possible with them.
4. HMOs want to usurp physicians' authority to determine patient care but want none of the responsibility for ensuring patient health.
