Nurses are ambivalent with regard to how they experience complex nursing care situations. The contextual conditions and the nurses' personal characteristics play a key role in whether nurses perceive complex nursing care situations as positive challenges or overwhelming burdens. These findings are important for managers, as they can support nurses to master complex nursing care situations.

The newly developed moral distress questionnaire appears to produce face validity and is sufficiently applicable for use in our study. The results indicate that moral distress appears to be a relevant phenomenon also in Swiss hospitals and that nurses were experiencing it prior to the introduction of Swiss diagnosis-related groups.

With the newly developed questionnaire to measure the complexity of nursing care in acute care hospitals it seems to be possible to assess and to quantify the complexity of nursing care in various acute care hospital settings. Based on the findings and the feedback of the participating users, the questionnaire needs to be improved for large-scale application.

Patient-related complexity of nursing care in acute care hospitalsan updated concept Rational: The interest in complexity of nursing care has grown in science and practice in recent years because of changed patient profiles and higher average levels of patient acuity in acute care hospitals. Aim: The aim of this study was to redefine the concept of patient-related 'complexity of nursing care' in acute care hospitals. Design: The hybrid model for concept development was chosen. Methods: In a first theoretical phase, we performed a narrative literature review regarding defining elements of patient-related 'complexity of nursing care' and developed a working definition. In the fieldwork phase, we investigated collective case studies representing 12 nursing care situations. The theoretical phase was updated before all findings were synthesised, and in the final analytical phase, the preliminary working definition was refined. Ethics: An ethical committee judged the study as unproblematic (waiver no. 82/14 from 5 December 2014). Results: The concept was redefined confirming previous understandings of patient-related 'complexity of nursing care' as a dynamic, relational concept characterised by the instability, variability and uncertainty that exist. The extent of complexity was determined by multifaceted patient problems and resources as well as extensive knowledge, experience, attention and caring skills of registered nurses interacting with each other. Limitations: The study did not include organisation-related complexity of nursing care. Conclusions: The redefinition of the concept may support a common understanding of patient-related demands on nursing care among practitioners, managers and politicians which is important regarding patient safety and health nursing staff.

AimMoral distress experienced by nurses in acute care hospitals can adversely impact the affected nurses, their patients and their hospitals; therefore, it is advisable for organizations to establish internal monitoring of moral distress. However, until now, no suitable questionnaire has been available for use in German‐speaking contexts. Hence, the aim of this study was to develop and psychometrically test a German‐language version of the Moral Distress Scale.DesignWe chose a sequential explanatory mixed methods design, followed by a second quantitative cross‐sectional survey.MethodsAn American moral distress scale was chosen, translated, culturally adapted, tested in a pilot study and subsequently used in 2011 to conduct an initial web‐based quantitative cross‐sectional survey of nurses in all inpatient units at five hospitals in Switzerland's German‐speaking region. Data were analysed descriptively and via a Rasch analysis. In 2012, four focus group interviews were conducted with 26 nurses and then evaluated using knowledge maps. The results were used to improve the questionnaire. In 2015, using the revised German‐language instrument, a second survey and Rasch analysis were conducted.ResultsThe descriptive results of the first survey's participants (n = 2153; response rate: 44%) indicated that moral distress is a salient phenomenon in Switzerland. The data from the focus group interviews and the Rasch analysis produced information valuable for the questionnaire's further development. Alongside the data from the second survey's participants (n = 1965; response rate: 40%), the Rasch analysis confirmed the elimination of previous deficiencies on its psychometrics. A Rasch‐scaled German version of the Moral Distress Scale is now available for use.
