Objektivizacija mjerenja radnoga opterećenja radiologa i procjena trenda u jedanaestogodišnjem razdoblju Objectification of measuring the workload of radiologists and estimate of the trend in the eleven-year period

摘要

The workload of radiologists has been commonly estimated by the number of performed procedures. More accurate estimates can be obtained using dimensionless units, which measure the workload of each radiological procedure (Relative Value Units, RVU). Using the RVU system the complexity of the radiological procedures can also be determined and analyzed.udIn studies on the radiologists workload data are usually collected by survey, and the unavailability of radiologists is usually neglected.udIn this work, a computational method for objective measurement of the workload of radiologists was developed. Data on the number of the procedures and radiologists who performed the procedures were collected from the archives of radiological reports and the RVU system developed by American Medical Association was used. Developed method was used on radiologic reports from eleven year period. Significant positive trend and seasonality of the workload was found. Also, there was a significant positive trend of the complexity of the radiologic procedures, as well as increasing homogeneity of the radiologists’ workload.
