Issues of knowledge, fears, motivation and potential psychological impact of performing CISC should be addressed prior to deciding on CISC and instructing patients. Follow-up care should be improved to include re-evaluations of skills, discussing adherence, integrating CISC in daily activities and general coping issues.

Few studies and little evidence were found for the relevance of team characteristics and team directed strategies in the implementation of nursing innovations. Feedback was most frequently used as a strategy. Leadership could be labeled as a team characteristic as well as a team directed strategy. Further research should be of good methodological quality and focusing on patient outcomes and time and costs invested in strategy delivery. This increases scientific knowledge on nursing implementation strategies focusing on leadership.

BackgroundThere is only limited understanding of why hand hygiene improvement strategies are successful or fail. It is therefore important to look inside the ‘black box’ of such strategies, to ascertain which components of a strategy work well or less well. This study examined which components of two hand hygiene improvement strategies were associated with increased nurses’ hand hygiene compliance.MethodsA process evaluation of a cluster randomised controlled trial was conducted in which part of the nursing wards of three hospitals in the Netherlands received a state-of-the-art strategy, including education, reminders, feedback, and optimising materials and facilities; another part received a team and leaders-directed strategy that included all elements of the state-of-the-art strategy, supplemented with activities aimed at the social and enhancing leadership. This process evaluation used four sets of measures: effects on nurses’ hand hygiene compliance, adherence to the improvement strategies, contextual factors, and nurses’ experiences with strategy components. Analyses of variance and multiple regression analyses were used to explore changes in nurses’ hand hygiene compliance and thereby better understand trial effects.ResultsBoth strategies were performed with good adherence to protocol. Two contextual factors were associated with changes in hand hygiene compliance: a hospital effect in long term (p < 0.05), and high hand hygiene baseline scores were associated with smaller effects (p < 0.01). In short term, changes in nurses’ hand hygiene compliance were positively correlated with experienced feedback about their hand hygiene performance (p < 0.05). In the long run, several items of the components ‘social influence’ (i.e., addressing each other on undesirable hand hygiene behaviour p < 0.01), and ‘leadership’ (i.e., ward manager holds team members accountable for hand hygiene performance p < 0.01) correlated positively with changes in nurses’ hand hygiene compliance.ConclusionThis study illustrates the use of a process evaluation to uncover mechanisms underlying change in hand hygiene improvement strategies. Our study results demonstrate the added value of specific aspects of social influence and leadership in hand hygiene improvement strategies, thus offering an interpretation of the trial effects.Trial registrationThe study is registered in ClinicalTrials.gov, dossier number: NCT00548015.

Professional nurses' associations are active in promoting evidence-based practice among their nurse members, but only those focusing on changing competences and attitude by addressing intrinsic motivation are well used. Other types of activities deserve to be explored, including behaviour-oriented approaches, approaches using structural, social or financial influence measures and perhaps methods based on 'involuntary involvement'.

The International Classification of Functioning, Disability and Health can be a useful tool in classifying and communicating aspects of patient functioning by nurses. A level of moderate detail within the Classification (three-digit level) seems appropriate for most nursing purposes. Our results on items that could be added or improved can serve as input in future revisions of the Classification. Future use of the International Classification should be encouraged, because of its relevance to nursing and its potential for multidisciplinary use in patient care.
