title: [Patients' beliefs about long-term glucocorticoid therapy and their association to treatment adherence].
abstract: BACKGROUND
  In patients treated with systemic glucocorticoids (GCs), it is unknown if beliefs about the treatment are associated with level of reported adherence.
  
  
  METHODS
  Cross-sectional study conducted in two departments of internal medicine during a six-month period. All patients receiving long-term GCs therapy were asked to fill in a questionnaire regarding their beliefs about (specific scale of the Beliefs about Medicines Questionnaire) and their adherence to (four-item Morisky-Green scale) GCs. Logistic regression analysis was used to assess association between beliefs about GCs and adherence to treatment.
  
  
  RESULTS
  One hundred and eighty one questionnaires were analysed (women: 79%, median age [IQR]: 47 [33-61] years, median duration of treatment: 18 [7-72] months, median daily dosage of prednisone equivalent: 10 [6-20] mg). Among these 181 patients, 83 (46%) reported a "concern" score equal to or higher than the "necessity" score. Nineteen percent of patients reported a low adherence level. In multivariate analysis, these patients were significantly younger (OR: 0.96 [0.93-0.98] per increasing year of age, P=0.002) and reported more frequently a "concern" score higher than a "necessity" score (OR: 3.08 [1.27-7.46], P=0.01) as compared to patients reporting a high adherence level.
  
  
  CONCLUSIONS
  Informing patients about the "necessity" of GCs and taking into account their "concerns" about adverse events or their fear of becoming dependent on the medication may improve their adherence to treatment.
