Riktigere bruk av laboratorietjenester - medisinske aspekter
Sammanfattning
INTERPRETATION : There are no known differences in morbidity between the northern and western health regions that can explain the observed variations in the use of laboratory tests. Our observations indicate a need for a thorough investigation of current utilisation of laboratory tests. Initiatives should be taken on a national basis to improve appropriate use.
RESULTS : We observed differences in the absolute frequency of requested tests and a marked variation in relative ratios (ratio between related tests) between the laboratories in northern and western Norway. Data from Haukeland University Hospital showed a mean increase of 12% (range: -24-54%) in the number of ordered tests between 2002-04.
MATERIAL AND METHODS : Production statistics for 2004 were obtained through a questionnaire sent to all public clinical chemistry hospital laboratories in northern and western Norway. Additional detailed production statistics were obtained from Haukeland University Hospital for 2002-04.
BACKGROUND : There has been a large increase in the use and costs of laboratory tests during recent years. Several reports have indicated excessive and inappropriate use. The purpose of this study was to assess the use of public laboratory services within clinical chemistry in two Norwegian health regions.
