Self-referrals in a Dutch Emergency Department: how appropriate are they?

Objective Self-referred visits account for an average of 30% of all Emergency Department (ED) visits in the Netherlands. Some of these are considered inappropriate, because patients receive care that a GP can provide. Worldwide, studies have used various methods to determine the proportion of inappropriate visits by self-referred patients, resulting in diverging percentages. The aim of this study was to find a reliable percentage of appropriate visits to the ED by self-referred patients in the Netherlands. Methods This observational, prospective study was performed in the ED of a hospital in the Netherlands. Data were collected on all self-referred patients in four separate months over 1 year. The appropriateness of an ED visit was determined at two time points: first, after primary assessment of the patient, using predefined criteria, and second the moment the patient left the ED, on the basis of the diagnosis and treatment received. Finally, the perspective of the patients was taken into account using a questionnaire. Results In 4 months 3196 self-referred patients were included. In all, 1862 (58.8%) visits were classified as appropriate according to the predefined criteria. When the second time point was taken into consideration, 48.1% of the patients had a secondary care diagnosis and/or needed secondary care treatment, classifying their visits as appropriate. According to the opinion of the patients 76.7% classified their visit as appropriate. Conclusion The percentage of appropriate ED visits by self-referred patients in the Netherlands ranges from 48.1 to 58.8%, as determined using two different methods.
