Objectives To characterize determinants of career satisfaction among pediatric hospitalists working in diverse practice settings, and to develop a framework to conceptualize factors influencing career satisfaction. Methods Semi-structured interviews were conducted with community and tertiary care hospitalists, using purposeful sampling to attain maximum response diversity. We employed close- and open-ended questions to assess levels of career satisfaction and its determinants. Interviews were conducted by telephone, recorded, and transcribed verbatim. Emergent themes were identified and analyzed using an inductive approach to qualitative analysis. Results A total of 30 interviews were conducted with community and tertiary care hospitalists, representing 20 hospital medicine programs and 7 Northeastern states. Qualitative analysis yielded 657 excerpts which were coded and categorized into four domains and associated determinants of career satisfaction: (i) professional responsibilities; (ii) hospital medicine program administration; (iii) hospital and healthcare systems; and (iv) career development. While community and tertiary care hospitalists reported similar levels of career satisfaction, they expressed variation in perspectives across these four domains. While the role of hospital medicine program administration was consistently emphasized by all hospitalists, community hospitalists prioritized resource availability, work schedule and clinical responsibilities while tertiary care hospitalists prioritized diversity in non-clinical responsibilities and career development. Conclusions We illustrate how hospitalists in different organizational settings prioritize both consistent and unique determinants of career satisfaction. Given associations between physician satisfaction and healthcare quality, efforts to optimize modifiable factors within this framework, at both community and tertiary care hospitals, may have broad impacts.
