The datasets contains all cleaned-up data used for analyses in the research described in the manuscript by Haenen and Colleagues (in progress). The paper addresses the hand hygiene compliance of employees from 14 Nursing homes (25 wards). Hand hygiene is regarded as the most effective means of reducing healthcare related infections and is easy to perform, despite this the hand hygiene compliance of healthcare workers in divers healthcare settings is low. We designed a tailored intervention strategy to improve hand hygiene in Dutch nursing homes. we tested our implementation strategy (CHANGE) in a stepped wedge cluster randomized trial which is based on a random sequential roll-out of the CHANGE implementation strategy to all participating LTCF wards (n=25) for comparison. A full description of the program as well as all measures is given in the method file (method-change-concept.docx). In this file you can also find a description of the process of data collection. The syntax file contains the syntax to the ITT analysis.
