Qualità della vita nell’osteoporosi – Icaro Abstract

Measurement of Quality of Life (QoL) in patients enrolled in the ICARO study (Incidence and ChAracterization of “inadequate treatment Responder patients” in Osteoporosis): results at follow-up after 12 months.

ICARO is a multicentre observational project aimed at assessing the outcome at the 12-month follow-up (longitudinal phase) in patients with severe osteoporosis and “inadequate response to antiresorptive treatment”, defined as patients prescribed with antiresorptive drugs (alendronate, risedronate and raloxifene) for at least 1 year and presenting a new fragility fracture (vertebral or non-vertebral).
Health-related quality of life (HRQOL) was measured by using the QUALEFFO-41 questionnaire, which includes the following domains: pain, activities of daily living, housework, mobility, leisure/social activities, general health perception, and mood. A score = 1 indicates the worst impact and a score = 5 is the best impact on HRQOL. The scores were linearly transformed to obtain a 0 to 100 score, corresponding to the best and the worst HRQOL, respectively. The mean (± SD) changes from baseline in patients with and without new incidental fractures in the follow-up period who answered at least 70% of items at both baseline and endpoint are shown in the following table. P values refer to the comparisons between subgroups (n = number of evaluable patients).

 

The occurrence of new fractures in the follow-up period caused a worsening of HRQOL (except changes of mood) and the difference between the two subgroups was significant (p<0.05) for mobility and general health perception. The comparison in patients with traumatic and non-traumatic fractures showed that the former group had higher worsening in any domain (not significantly between groups), while the analysis in patients with symptomatic and symptoms-free fractures showed that symptoms caused a more marked worsening of HRQOL (significantly between groups for pain, p = 0.040, and mood, p = 0.003).
These data show that the occurrence of new fractures is associated with a deterioration of HRQOL parameters, being impairment of mobility and of ability in daily activities the most important factor that caused a poor general health perception.
