Organizational health literacy (OHL) is crucial for public health, in turn health care organizations play vital roles in improving populations' health literacy. Therefore, the aim of this qualitative study was to explore how the organizational health literacy self-assessment tool (OHL Self-AsseT) was implemented, used, and understood by primary care teams from a network of general practices and a Home Care Service Organization in Zurich, Switzerland. Reflexive thematic analysis with a constructivist orientation was used to analyze data from 19 interviews pre- and post-OHL Self-AsseT use. Normalization Process Theory supported structuring of inductively developed themes. Findings show that the participants experienced working with the OHL Self-AsseT meaningful, as it helped with "Addressing OHL construction sites" so that they could "build momentum for change". The experience of "Succeeding together in construction" led to a "feeling of team-efficacy during change". Practical use of the tool and/or discussions about OHL led to a growing conceptual understanding, which was described as "Using a construction plan-making sense of ongoing OHL activities". To conclude, the OHL Self-AsseT encouraged teams to initiate change, led to greater team-efficacy and supported the construction of OHL. Improved implementation strategies will support this intervention's scale-up as a base for effectiveness testing.
