Abstract
Since 1993, nurses in a surgical ward have been working with quality development related to patients with peripheral intravenous line. The aim of this study was to describe the process of this development. The DySSSy-method (Dynamic Standard Setting System), a method for establishing quality goals for structur, process and outcome, is a practical approach which was used to assure the quality of care. The method facilitates the identification of quality indicators. Nine quality indicators have been measured 13 times. One indicator is for example, Number of patients with cannulae in place less than 24 hours, related to, the total number of patients with cannulae. The conclusion is that quality development with indicators, regularly measured, raised the quality of care for the patients.
