Objecive: To investigate temporal trends in the individual workload of nuclear medicine physicians at a large tertiary care academic center between 2008 and 2023., Methods: This study analyzed the reporting workload of nuclear medicine physicians in a large tertiary care academic center in The Netherlands on 36 unique (randomly sampled) calendar days, for each year between 2008 and 2023. The average daily departmental workload (measured with relative value units) was calculated for each year between 2008 and 2023. The individual workload was calculated by dividing the average daily departmental workload in each year by the available full-time equivalent nuclear medicine physicians in each year. Mann-Kendall tests were used to assess for any temporal monotonic trends in individual workload and types of nuclear medicine procedures performed., Results: Individual workload increased significantly between 2008 and 2023 (Mann-Kendall tau of 0.611, P = 0.001). Individual workload in 2023 was 86% higher than in 2008. The use of positron emission tomography (PET) increased significantly (Mann-Kendall tau of 0.912, P < 0.001) between 2008 and 2023. The use of diagnostic scintigraphy decreased significantly in the same period (Mann-Kendall tau of -0.817, P < 0.001). The use of DEXA also showed a significant decrease (Mann-Kendall tau of -0.467, P = 0.013), but this decrease was negligible on a relative scale. The number of therapeutic procedures (Mann-Kendall tau of -0.100, P = 0.626) remained statistically stable in this period., Conclusions: Our single-center study showed that the individual workload of nuclear medicine physicians has increased significantly between 2008 and 2023, driven by the rise in PET scans. The demand for both diagnostic and therapeutic nuclear medicine procedures and associated workload is expected to keep on increasing in the foreseeable future. This workload trend should be taken into account by policymakers involved in nuclear medicine staffing planning. A healthy balance between the nuclear medicine workforce and workload is necessary to maintain the quality of care, to be able to perform other important (academic) tasks such as research, educating and training medical students and residents, and management, and to prevent physician burnout and dropout., Competing Interests: Declarations. Ethical approval: This retrospective study was approved by the local ethical review board, and the requirement for informed consent was waived., (© 2024.

Background: The workload of musculoskeletal radiologists has come under pressure. Our objective was to estimate the reading times of common musculoskeletal MRI examinations., Methods: A total of 144 radiologists were asked to estimate reading times (including interpretation and reporting) for MRI of the shoulder, elbow, wrist, hip, knee, and ankle. Multivariate linear regression analyses were performed., Results: Reported median reading times with interquartile range (IQR) for the shoulder, elbow, wrist, hip, knee, and ankle were 10 (IQR 6-14), 10 (IQR 6-14), 11 (IQR 7.5-14.5), 10 (IQR 6.6-13.4), 8 (IQR 4.6-11.4), and 10 (IQR 6.5-13.5) min, respectively. Radiologists aged 35-44 years reported shorter reading times for the shoulder (β coefficient [β] = B-3.412, p = 0.041), hip (β = -3.596, p = 0.023), and knee (β = -3.541, p = 0.013) than radiologists aged 45-54 years. Radiologists not working in an academic/teaching hospital reported shorter reading times for the hip (β = -3.611, p = 0.025) and knee (β = -3.038, p = 0.035). Female radiologists indicated longer reading times for all joints (β of 2.592 to 5.186, p ≤ 0.034). Radiologists without musculoskeletal fellowship training indicated longer reading times for the shoulder (β = 4.604, p = 0.005), elbow (β = 3.989, p = 0.038), wrist (β = 4.543, p = 0.014), and hip (β = 2.380, p = 0.119). Radiologists with <5 years of post-residency experience indicated longer reading times for all joints (β of 5.355 to 6.984, p ≤ 0.045), and radiologists with 5-10 years of post-residency experience reported longer reading time for the knee (β = 3.660, p = 0.045) than those with >10 years of post-residency experience., Conclusions: There is substantial variation among radiologists in reported reading times for common musculoskeletal MRI examinations. Several radiologist-related determinants appear to be associated with reading speed, including age, gender, hospital type, training, and experience.
