Qualitative and Quantitative Workplace Analysis of Staff Requirement in an Academic Radiology Department

Abstract

Purpose The role of today’s hospital-based radiologists goes far beyond interpretation-related tasks. This observational study defines these types of activities and quantifies the type of value-adding interactions radiologists experience on a daily basis with referring departments and other health personnel. The purpose of this study is to evaluate the quality and quantity of these value-adding non-image interpretation tasks in the daily routine of hospital-based residents and attending radiologists.

Methods A prospective, observational study was performed in the radiology department of a German university hospital. Two experienced radiologists performed a 30-day observation of the entire medical staff. The observers followed the subject radiologists throughout the workday, recording activities using a time and motion methodology. An evaluation matrix was developed to characterize and quantify image interpretation tasks (IITs), non-image interpretation tasks (NITs), and contingency allowance (CA) for residents and attending radiologists. Here, the example of the MRI unit is used.

Results Four main categories of responsibilities for NITs were identified including teaching and education, clinical decision support, management and organization, and patient care. The quantitative analysis for residents showed: IITs 15 h/d (53 %), NITs 9.8 h/d (34 %), CA 2.2 h/d (13 %). For attendings the analysis revealed: IITs 6.7 h/d (40 %), NITs 7.8 h/d (47 %), and CA 1.7 h/d (13 %). This resulted in staff requirements of 2 attendings and 3.4 residents for the MRI unit. On average, 6 TSEs/h occurred in the case of residents and 13 TSEs/h in the case of attendings.

Conclusion NITs consumed a significant portion of a radiologist’s workday. Therefore, the number of examinations performed is not a reliable surrogate for the daily workload of hospital-based radiologists especially in cross-sectional imaging units. Though time-consuming, these non-interpretive tasks are greatly contributing to the fact that modern radiology is assuming a central position in patient management, fulfilling a critical role that surpasses image interpretation-related tasks to include a more integrative and consultative role. These findings will help to further define the changing role of radiologists with respect to other physicians, non-medical personnel, hospital administrators, as well as policy makers.

Key points: 

• Staff requirements are a significant factor in department strategy.

• Targeted analysis can deliver valuable information about workload per activity and the required staff.

• The number of examinations performed is not a reliable surrogate for the daily workload of hospital-based radiologists.

• NITs comprise a significant portion of a radiologist’s workday.

• Though time-consuming, non-interpretive tasks contribute to the fact that modern radiology is assuming a central role in patient management.
