Determinants of radiologists' desired workloads

Area of Science:

• Medical Imaging and Radiology
• Health Services Research
• Workforce Studies

Background:

• Understanding factors influencing radiologists' desired work hours is crucial for workforce planning.
• Work intensity, measured as procedures per hour, is a key but often overlooked variable.
• Previous studies have not fully explored the relationship between work intensity and desired workload.

Purpose of the Study:

• To identify the determinants of desired work hours among radiologists.
• To specifically investigate the impact of work intensity on radiologists' desired annual workloads.
• To analyze how individual and practice characteristics influence workload preferences.

Main Methods:

• Utilized weighted data from the American College of Radiology's (ACR) 2003 survey.
• Employed multiple linear regression analysis to examine influencing factors.
• Focused on work intensity (procedures per work hour) as a primary variable.

Main Results:

• A 1 procedure/hour increase in work intensity correlated with a 2.3-hour decrease in desired annual work.
• Older radiologists (≥65 years) desired significantly fewer hours (262 fewer) than middle-aged counterparts (45-54 years).
• Radiologists in academic practices desired more hours (213 more) than those in private groups; regional differences also noted.

Conclusions:

• While increased work intensity is associated with seeking fewer hours, its effect is marginal.
• Radiology practices are likely to continue managing workload by increasing intensity rather than extending hours.
• Age, practice setting, and geographic region are significant factors influencing radiologists' desired work hours.
