CT (computed tomography) scanners. Methodological note No. 1
Technical Report

OSTI ID:5926695
Flexible need methodologies and planning efforts for computed tomography (CT) scanners are needed to address future utilization rates and technological developments. The 'Leonard methodology' multiplies the number of patients in each disease category diagnosable by a CT scanner by a conversion factor to estimate the number of patients that would benefit from an initial CT scan. This number is then adjusted to estimate the number of follow-up procedures and outpatient procedures generated by a hospital's patients. Other methods suggested include: (1) a weighting formula which expresses a composite weighted scanning volume in head-equivalent CT (HECT) units and (2) a sliding scale which calculates utilization levels using various slice times and a ratio of head to body scans. A standard of 3,500-4,000 HECTs per year, a level comparable to the previous target of 2,500 patient procedures, has been proposed. Adjustments based on local conditions such as data availability and service accessibility were recommended with this standard. Included are: Block McGibony and Associates' Planning for Computed Tomography (CT) Scanning: Considerations for Planners and Providers, which endorses the Leonard methodology; G. M. K. Hughes' 'National Survey of Computed Tomography Unit Capacity,' which proposes the HECT standard; the National Council on Health Planning and Development's proposed standard for CT scanners; and methodologies from the 1980 Missouri State Health Plan and the 1980/81 Southeastern Wisconsin Health Systems Plan.
