Über den Autor Derkx, Hay
Hay Derkx (24-9-1949) worked as physician in Malawi for 3 years and as a general practitioner at Berg en Terblijt. In 2001 he became involved in the development of "The Health line", a medical call centre. As a result of this experience he became increasingly fascinated by the phenomenon of telephone triage which resulted in this thesis.
