As the application of lean in healthcare expands, further research is needed in at least two areas: first, on the role of context in shaping lean and its consequences and second, on how healthcare workers perceive lean. Accordingly, this context-sensitive, mixed methods study addressed how hospital workers' perceptions of lean varied across contexts in three Swedish hospitals. Registered nurses and physicians at the hospitals and across units differing in acuity completed standardized surveys (N=236, 57% response rate) about their perceptions of hospital-wide lean implementation. Perceptions varied by: hospital context, with one hospital's employees reporting the least favorable perceptions; unit acuity, with higher-acuity units reporting more favorable perceptions; and professional role, with nurses reporting more favorable perceptions than physicians. Individual interviews, group interviews, and observations provided insight about these dissimilar contexts and possible explanations for context-specific variability. Findings are discussed with respect to strategies for implementing lean in healthcare; the importance of attending to levels, context, and worker consequences of lean; and directions for future research.

Healthcare organisations in Sweden are reorienting toward horizontal organisation around care processes. This paper's aim was to investigate how implementation approaches for improvements of care processes in line with lean production (LP), at hospital strategic and operative levels, are associated with working conditions and stress-related health among the employees. Five hospitals working with improvements to care processes were studied using questionnaires to employees (n = 1,303) and interviews at strategic and operative levels at baseline and follow-up. The process redesign implementation strategies varied between the strategic and operative levels. 236 L. Dellve et al.There were associations between a higher degree of LP at operative level and increased work resources and decreased work demands. Physical, cognitive and mental stress-related symptoms were only weakly associated with strategic or operative LP initiatives. There was evidence of more beneficial or improved working conditions in relation to higher degree of LP at operative levels.Keywords: lean production; continuous improvements; work environment; psychosocial work conditions; healthcare service; human factors; implementation; stress; healthcare workers; Sweden.

Background: Swedish health care organizations (HCOs) are changing using management concepts such as Lean, in attempts of improving efficiency, quality of care and work environment. Since there are pre-conditional challenges for operative managers to engage in change, HCOs tend to assign supportive functions such as change agents (CAs) to facilitate change. Research on the use of CAs in HCOs is sparse, thus the aim of this study explores role assignments and conditions of formally appointed CAs contributing to care process redesign. Methods: A purposive sample of three Swedish hospitals initiating Lean-inspired care process redesign during 2010-2011 was done. In-depth interviews were held with fifty-one key functions during change. Focus group interviews were conducted with thirty-eight health care professionals. Data were analysed by content analysis. Results: Top managers' goal was to have operative management responsible for change during care process redesign, with support from assigned CAs. Organizing of CAs varied concerning, e.g. their hierarchical positions, job descriptions and practices, and conditions to act as driving forces towards change. Being granted formal power, having earned legitimacy and credibility, clarity regarding roles and responsibilities in change; a good sense of timing and ability to build relationships and trust, were identified as beneficial for CAs to support change. Conclusions: Role assignment and organizing of CAs varies. A position closer to the operative levels, formalized and clarified responsibilities, earned legitimacy and timing support adaptation and alignment of planned change, such as Lean-inspired care process redesign.
