title: Preference for erectile dysfunction treatments: Assessment by means of consumers preference analysis techniques.
abstract: BACKGROUND
  Patient preference for erectile dysfunction (ED) treatments is of great importance for satisfaction and adherence. We have assessed the usefulness of the main technique for assessing consumer preferences (conjoint analysis) to analyze preferences towards these treatments. We also assessed the influence of age, frequency of sexual intercourse, co-morbidities, ED severity or having testosterone deficiency syndrome (TDS).
  
  
  METHODS
  Observational, cross-sectional, multicenter study in 626 men aged ≥18 years that had recently taken at least two different PDE5i, one being vardenafil orodispersible (ODT). Seven selected features of ED treatments were tested. Different series of scenarios (cards) were created by combining these features: two series of 4 features (9 cards), another one series of 7 (16 cards). Short series were tested in Primary Care, and the long series in Urology/Andrology offices. Influences were tested by rank ordered logistic regression analysis.
  
  
  RESULTS
  The feature «administration form» was consistently given the most relative importance; the ODT form was given the greatest utility. Consensus towards the most and least preferred treatment was achieved only in one of the short series tested. Only severity of TDS symptoms, or having the most frequent symptoms, influenced treatment preference. Influence was mild.
  
  
  CONCLUSIONS
  Conjoint analysis is a valid method for assessing preferences for ED treatments. A short series of highly selected attributes is advisable. Easiness and convenience of administration are of great importance for users. TDS symptomatology mildly affects preference.
