The hospital management wishes to guarantee a high quality of care by improving processes. Th improvement is based upon performance measurements documented by care providers using an order communication, planning and result reporting system. The nursing process was integrated in clinical pathways. The documented data to guide the nursing care process and used for quality improvement are off poor quality. The documentation process was improved by setting up a structured organisation of data collection into the HIS, based on a clear procedure, discussed with care providers to make sure the data collection was achievable A control mechanism of measured data has been organised. The responsibility for gathering correct data was identified and a structured follow up was organised. Feed back and discussion of data and information of the responsible team was organised. After the implementation of this method more accurate measurements were noticed. More correct data for additional improvement of the process were used. Based upon these structured approach other processes will be improve.
