Association between the correct use of intranasal aerosols and symptom improvement in allergic rhinitis

Allergic rhinitis (AR) is highly prevalent worldwide. Good patient adherence ensures successful treatment. This study aimed to identify the association between the intranasal aerosol technique and symptom improvement. This is an analytical, prospective, and longitudinal study that included 36 patients diagnosed with AR. The Rhinitis Control Assessment Test (RCAT) questionnaire was administered to both an experimental population and a control group. The 11 steps of the intranasal aerosol technique were explained to the experimental group, and performance was graded using a pamphlet for patient follow-up in subsequent controls. Of the participants, 63.9% were women and 36.1% were men, with a median age of 30 years (IQR 24-42) and an age range from 18 to 69 years. An average RCAT percentage of 55.6% was observed in both groups during the first consultation. On the second visit, a difference in disease control was noted. In the experimental group, 83.3% had controlled symptoms, whereas only 61.1% of the control group did. At the third visit, 76.5% of the experimental group had controlled symptoms, compared to 58.8% of the control group. In the experimental group, 52.9% of patients demonstrated good technique, while only 5.9% in the control group did (p=0.004). Patient education and training, compared to an untrained group, benefit the patient by aiding in the remission of symptoms and improving quality of life.
