title: Patient preferences for route of allergy immunotherapy: a comparison of four delivery methods.
abstract: Allergen-specific immunotherapy (IT) is a disease-modifying treatment for allergic rhinitis, and adherence to the treatment schedule is important for a successful outcome. Several methods for delivering IT are now available, but little information is known concerning patient preference for these options.
  
  
  
  Over a 12-month period, 228 adults scheduled to undergo outpatient allergy testing were offered a survey to rank 4 different IT delivery methods: subcutaneous IT (SCIT), sublingual IT using liquid extracts (SLIT), sublingual allergy immunotherapy tablets (AIT), and oral mucosal immunotherapy (OMIT) using a toothpaste delivery vehicle.
  
  
  
  Of the participants who completed the survey, ranking scores (mean ± SD) for SCIT, SLIT, AIT, and OMIT, with 1 being the highest rank, were 3.36 ± 1.02, 2.03 ± 0.92, 2.30 ± 1.02, and 2.32 ± 1.05, respectively. The number of participants who ranked SCIT, SLIT, AIT, or OMIT as their number 1 choice was 24 (10.5%), 79 (34.6%), 61 (26.8%), and 64 (28.1%), respectively. When comparing first choice rankings, there were no statistically significant differences between SLIT, AIT, or OMIT, yet all 3 groups ranked higher than SCIT (p < 0.0001).
  
  
  
  SCIT earned the lowest mean rank and had the least number of participants rank it as the most preferred method. Among the other 3 choices, by mean scores, SLIT was preferred most compared to either AIT or OMIT; but when considering first choices only, there were no significant differences in preference. Most of the study participants identified the convenience of home IT administration as the most important factor in their ranking.
