  • Inpatients were subdivided according to the peer hospital area, and outpatients according to the source (GP or ambulatory care clinic).

  • The frequency of inappropriate retesting was higher among inpatients than outpatients for vitamin D (χ2=324.9, p<0.001), vitamin B12 (χ2=6.9, p=0.009) and folate (χ2=5.9, p=0.015).
