ImportanceAdministrative harm (AH), defined as the adverse consequences of administrative decisions within health care that impact work structure, processes, and programs, is pervasive in medicine, yet poorly understood and described.ObjectiveTo explore common AHs experienced by hospitalist clinicians and administrative leaders, understand the challenges that exist in identifying and measuring AH, and identify potential approaches to mitigate AH.Design, Setting, and ParticipantsA qualitative study using a mixed-methods approach with a 12-question survey and semistructured virtual focus groups was held on June 13 and August 11, 2023. Rapid qualitative methods including templated summaries and matrix analysis were applied. The participants included 2 consortiums comprising hospitalist clinicians, researchers, administrative leaders, and members of a patient and family advisory council.Main Outcomes and MeasuresQuantitative data from the survey on specific aspects of experiences related to AH were collected. Focus groups were conducted using a semistructured focus group guide. Themes and subthemes were identified.ResultsForty-one individuals from 32 different organizations participated in the focus groups, with 32 participants (78%) responding to a brief survey. Survey participants included physicians (91%), administrative professionals (6%), an advanced practice clinician (3%), and those in leadership roles (44%), with participants able to select more than one role. Only 6% of participants were familiar with the term administrative harm to a great extent, 100% felt that collaboration between administrators and clinicians is crucial for reducing AH, and 81% had personally participated in a decision that led to AH to some degree. Three main themes were identified: (1) AH is pervasive and comes from all levels of leadership, and the phenomenon was felt to be widespread and arose from multiple sources within health care systems; (2) organizations lack mechanisms for identification, measurement, and feedback, and these challenges stem from a lack of psychological safety, workplace cultures, and ambiguity in who owns a decision; and (3) organizational pressures were recognized as contributors to AHs. Many ideas were proposed as solutions.Conclusions and RelevanceThe findings of this study suggest that AH is widespread with wide-reaching impact, yet organizations do not have mechanisms to identify or address it.
