This category includes randomized clinical trials and studies that measure the accuracy of diagnostic tests. The centers should emphasize primely technology assessment.

The conclusions of earlier studies have also often had limited applicability because of bias in patient selection and because the study was earned out at a single institution. Multicenter collaborative studies can involve many types of hospitals, from HMOs to university medical centers.

From page 122... ...
For the technology assessment laboratory to be able to respond rapidly to new technological innovation, all of the major clinical deparunents must be involved and represented on its staff. Beyond the primary group of investigators, there must be a support structure consisting of faculty in biostatistics, economics, sociology, epidemiology, engineenng, law, and me behavioral sciences.

The number of primary technology assessments mat can be performed at one time win depend on me rate of enrobing patients and on Me level of fiscal support for We centers. Secondary technology assessment.

S=y Personnel Several types of study personnel will be required. The exact mix of these is difficult to establish in advance, but experience with clinical studies suggests the foBow~ng configuration: Principal investigator.

Budget To estimate a budget for each participating center, we assume that each center will provide partial salary support for the principal investigator, several coBaboradng subspecialists, a statistician, a decision analyst, and a health economist. The center will support full-time positions for two nurse clinicians, two research assistants, one data entry clerk, one secretary, and one study coordinator.

An exception is a recent study in which samples from a single person were sent to many medical centers for serum cholesterol measurement. The institutions varied widely in He concentration of total cholesterol that they reported (College of American Pathologists 1987~.

From page 128... ...
In planning a technology assessment, physicians define the gold-standard tests that win be used to determine the true state of the patient. These may vary from surgery, autopsy, or biopsy to We results of another test, or even the results of long-term surveillance to detect disease missed by the index test.
