[Prevalence of criteria indicating bone densitometry and risk factors for low bone mass and fracture in rheumatology outpatient units]

Abstract

Many organisms have proposed criteria to identify individuals with low bone mass or increased risk for osteoporotic fracture in order to provide them with the available diagnostic and therapeutic resources. Among these organisms are the WHO, the Catalan Agency for Health Technology Assessment (CAHTA) and the International Committee for Osteoporosis Clinical Guidelines (ICOCG). We designed a prospective multicenter study to determine the prevalence of indications for bone densitometry in rheumatology outpatient clinics by applying the criteria of these three organisms. Two hundred sixty-two women and 98 men aged 18 years or older who attended five rheumatology outpatient clinics were interviewed and their medical records were reviewed. The mean age was 58.3±13.4 years. Bone densitometry was indicated in 45% of the patients interviewed according to the CAHTA criteria, in 77% according to the WHO criteria and in 62% according to the ICOCG criteria (applicable only to women). The proportion of patients with indications for bone densitometry increased with age, and was higher in women. The concordance among criteria was low.
