Resource requirements for interventional radiologic management of long- term ambulatory hemodialysis patients

OBJECTIVE: The purpose of this study was to determine how many and what type of procedures a vascular and interventional radiology service should provide for patients at ambulatory-patient dialysis centers and to determine the necessary resource requirements. These data may provide a realistic starting point for those engaged in the planning and provision of contractual services to dialysis centers. MATERIALS AND METHODS: Patient records at three dialysis centers for a recent 3- year period were examined, and demographic and clinical data were recorded. Records were cross-correlated with records from the vascular and interventional radiology service that had contractually provided all dialysis-related procedures. These data generated a monthly procedure volume and case mix per 100 dialysis patients. Facility usage times for 121 dialysis-related procedures were obtained prospectively and used to calculate the expected resources needed to service the dialysis patients. RESULTS: The three centers provided 5795 hemodialysis-months to 386 patients. Of the 386 patients over the 36- month period, 101 died and 92 transferred from the centers. Three hundred and sixteen patients required 1580 interventional procedures. Monthly procedure volume per 100 dialysis patients averaged 27.1 procedures. Observed procedure times were used to calculate expected room-time hours required to service the monthly procedural volume and case mix per 100 dialysis patients. CONCLUSION: On average, 500 ambulatory dialysis patients will require the full-time use of an interventional suite and the services of a full-time technologist, nurse, and physician to provide necessary dialysis-related procedures. If resources cannot accommodate this volume, the quality and timeliness of care for these patients is jeopardized.
