Background:
We considered the factors of poor adherence to and dropout from sublingual immunotherapy (SLIT) by verifying patient backgrounds 1 year after start of treatment.
Methods:
We recruited 38 patients who began SLIT between November 2014 and September 2015. We analyzed their attributes and level of understanding of the treatment, and conducted a self-reported survey on factors behind dropout cases and poor adherence cases.
Results:
Four patients dropped out 1 year after start of treatment. Three left for reasons related to anxiety about side effects. There were five cases of poor adherence. There was no significant difference between good adherence, poor adherence, and dropout regarding level of understanding of the treatment (p=0.59). In the comparison between good and poor adherence groups, except four dropout patients, the adherence tended to be poor in patients with short duration of disease, smoking patients, and young patients. Continuous rate of SLIT achieved about 90%, suggesting relatively high level of adherence.
Conclusion:
It appears possible that anxiety related to side effects could be a factor affecting dropout from SLIT. There was no significant difference regarding level of understanding of the treatment. The adherence tended to be poor in patients with short duration of disease, smoking patients, and young patients.
