Capitated contracting in radiology: negotiating techniques, financial calculations, and utilization management.

The authors describe how to develop and manage a capitated outpatient radiology contract. Aspects of a capitated fee structure and the need to apportion fees between a hospital and its radiology group are discussed. During negotiations with a managed care organization (MCO), certain information and commitments should be obtained. Utilization data should also be obtained from the MCO, but if they are not available (or are thought to be unreliable), certain norms can be used. Once a utilization projection is arrived at, reimbursement calculations can be made and compared with assumed reimbursements under a known fee schedule, such as that of Medicare. This procedure allows one to estimate whether a capitated proposal is financially feasible. Once a contractual agreement is instituted, the radiology group must then track and manage utilization. An understanding of these principles should enable radiologists to deal effectively with both practice and fiscal concerns presented by managed care.

Cost containment in the use of low-osmolar contrast agents: effect of guidelines, monitoring, and feedback mechanisms.

PURPOSE: To describe a program for controlling intravenous use of low-osmolar contrast agents (LOCAs). MATERIALS AND METHODS: The department of radiology at the authors' institution adopted a policy of selective use of intravenously administered LOCAs. Clinical indications for LOCA use were specified after consultation with the administration, risk managers, legal department, and ethics committee of the hospital. The guidelines were then publicized throughout the department and hospital, and a contrast agent data form was developed to collect data on all cases. Monitoring mechanisms were instituted. RESULTS: Over the next 23 months, 11,373 patients received intravenous iodinated contrast agents, of whom 28.1% were deemed to be at high risk and were given LOCAs. Monthly tracking showed no evidence of a trend toward increasing use of LOCAs. CONCLUSION: Clear definition of use guidelines, close monitoring, and feedback can stabilize LOCA use at acceptably low levels.

Laser modification to an x-ray collimator: an aid in positioning patients for neurosurgical and radiographic procedures.

In high-ambient-light levels such as are found in operating rooms, and at long target-to-patient distances, the cross lines and light field projected from conventional x-ray collimators are not easily visible and proper patient positioning is difficult. The collimators on two mutually perpendicular x-ray units have been modified by replacing the incandescent bulbs with lasers and adjusting the lasers to be coaxial with the x-ray beams. These modifications have been coupled with a third wall-mounted laser to facilitate patient positioning for stereotaxic thermal hypophysectomy. The use of the laser-modified collimators has resulted in considerable saving of time for the operating team and has markedly reduced patient anesthesia time. The laser-modified collimator has also been found useful in positioning patients for other radiographic procedures in the operating room and has virtually eliminated retakes due to malpositioning.
