BackgroundNew Public Management theory affected reforms of public sectors worldwide. In Italy, an important reform of the healthcare sector changed the profile of public hospitals, creating new management related positions in 1992. The reform defined the role of the clinician-manager: a hybrid figure, in charge of managing an entire unit. This paper aims to investigate how much clinician-managers feel like managers and how much they still feel like professionals, using time as a driver to conduct the analysis.MethodsA survey-questionnaire was administered to a set of 2,011 clinician-managers employed in public hospitals, with a response rate of 60.42%. The managerial role of healthcare professionals in public hospitals: A time-driven analysis of their activities. The questionnaire aimed to identify the difference between how much time clinician-managers actually spend on daily activities and how much time they would think be appropriate. To better cluster different type of management styles, subgroups were identified based on the type of organisations respondents work for, geographical location, and professional specialty.ResultsFindings suggest that clinician-managers spend more time on clinical activities than management. Clear differences are found according to professional specialty, and there are fewer differences in geographical location and the type of organisation.ConclusionsThe absence of clear differences in the responses between different geographical areas implies that a shared organisational culture characterizes the whole sector. However, differences in how the clinician-manager role is perceived based on the professional specialty suggest that closer integration may be needed.Supplementary InformationThe online version contains supplementary material available at 10.1186/s12913-023-09395-7.
