[Critical thinking among nurses during unit-based quality assurance projects].

The purposes of this study were to describe the objectives and levels of critical thinking among nurses during unit-based quality assurance projects and the meaning of the participation for their own development and nursing practice. The data were collected by interviewing ten nurses who had taken part in the quality assurance projects. The themes used in interviews were created on the basis of two open questions answered by 28 nurses. The data were analysed by using qualitative content analysis and applying the levels of reflective thinking developed by Mezirow (1981), Goodman (1984) and Järvinen (1990). The first level of critical thinking was defined as technical thinking, the second level as reflective thinking and the third level as critical reflection. The results showed that nurses reflected the structural factors of the quality assurance on the technical level. When reflecting their own quality assurance processes (process factors) nurses used their critical thinking on all levels. Very few nurses considered the outcome factors of the quality assurance, but when they focused their thinking on the outcomes the reflection reached all levels. The nurses reflected the meaning of the quality assurance projects on all three levels. According to the nurses, the quality assurance enhanced their professional abilities as well as motivation in work and self-esteem. The quality assurance projects also clarified the principles guiding nursing practice. Interaction between nurses, patients and colleagues became more open.
