LUP is conducted under an agreement between the Danish government and the Danish Regions. The survey was also conducted in 2000, 2002, 2004 and 2006. Since 2009, following a change of concepts, it is carried out as an annual, nationwide survey, investigating the experiences of both inpatients and outpatients in Danish hospitals.
In its new form, the survey presents the results at four distinct levels: national, regional, hospital and unit level. This provides the opportunity for individual units to be evaluated and to identify areas for improvement of patient experiences.
