      <i>Background</i> - A vast body of literature has documented regional variations in healthcare utilization rates. The extent to which such variations are “unwarranted” critically depends on whether there are corresponding variations in patients’ needs. Using a unique medical registry, the current paper investigated any associations between utilization rates and patients’ needs, as measured by two ...

Consequently, it rates raised questions as to what determines when to treat a patient. After Wennberg and Gittelsohns’ paper ‘Small Area Variations in Health Care Delivery’ was pub-lished in 1973, it became clear ...

    • Related variations: A novel approach for detecting patterns of regional variations in healthcare utilisation rates 

      Rudolfsen, Jan Håkon; Olsen, Jan Abel (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-06-22)
      Regional variations in healthcare utilisation rates are ubiquitous and persistent. In settings where an aggregate national health service budget is allocated primarily on a per capita basis, little regional variation in total healthcare utilisation rates will be observed. However, for specific treatments, large variations in utilisation rates are observed, iymplying a substitution effect at some ...
