  • Ruling out cardiac failure : Cost-benefit analysis of a sequential testing strategy with NT-proBNP before echocardiography
  • 2013

    • Objectives. To estimate the possible economic benefit of a sequential testing strategy with NT-proBNP to reduce the number of echocardiographies.Methods. Retrospective study in a third-party payer perspective. The costs were calculated from three Swedish counties: Blekinge, Östergötland, and Uppland. Two cut-off levels of NT-proBNP were used: 400 and 300 pg/mL. The cost-effectiveness of the testing strategy was estimated through the short-term cost avoidance and reduction in demand for echocardiographies.Results. The estimated costs for NT-proBNP tests and echocardiographies per county were reduced by 33%–36% with the 400 pg/mL cut-off and by 28%–29% with the 300 pg/mL cut-off. This corresponded to a yearly cost reduction of approximately €2–5 million per million inhabitants in these counties.Conclusion. The use of NT-proBNP as a screening test could substantially reduce the number of echocardiographies in the diagnostic work-up of patients with suspected cardiac failure, as well as the associated costs.

  • Reference values of thirty-one frequently used laboratory markers for 75-year-old males and females
  • 2012
  • Ingår i: Upsala Journal of Medical Sciences. - : Uppsala Medical Society. - 0300-9734 .- 2000-1967. ; 117:3, s. 264-272
  • Tidskriftsartikel (refereegranskat)abstract
    • Background.We have previously reported reference values for common clinical chemistry tests in healthy 70-year-old males and females. We have now repeated this study 5 years later to establish reference values also at the age of 75. It is important to have adequate reference values for elderly patients as biological markers may change over time, and adequate reference values are essential for correct clinical decisions.Methods.We have investigated 31 frequently used laboratory markers in 75-year-old males (n = 354) and females (n = 373) without diabetes. The 2.5 and 97.5 percentiles for these markers were calculated according to the recommendations of the International Federation of Clinical Chemistry.Results. Reference values are reported for 75-year-old males and females for 31 frequently used laboratory markers.Conclusion.There were minor differences between reference intervals calculated with and without individuals with cardiovascular diseases. Several of the reference intervals differed from Scandinavian reference intervals based on younger individuals (Nordic Reference Interval Project).
