ABSTRACT
BACKGROUND: Little is known about rhinitis control in real-life, nor about the contribution of treatment-related and patient-related factors. OBJECTIVE: This study aimed to examine the level of rhinitis control and rhinitis medication utilization in patients with persistent rhinitis, and to identify predictors of rhinitis control. METHODS: A cross-sectional observational study was conducted in patients with persistent rhinitis recruited in community pharmacies. Participants completed the Rhinitis Control Assessment Test (RCAT), and a questionnaire on patient/rhinitis characteristics, and rhinitis medication use. A visual analogue scale (VAS) for nasal symptoms was also completed. Pharmacy dispensing data was used to calculate adherence to intranasal glucocorticoids. Nasal spray technique was evaluated using a standardized checklist. Predictors of rhinitis control were explored using a linear regression model. RESULTS: A total of 1514 patients, recruited in 215 pharmacies, participated in the study (mean age 48.7 years, 62% female). Almost 60% exhibited suboptimal rhinitis control (RCAT ≤ 21/30). A 50mm cut-off on the VAS yielded 78.1% sensitivity to identify suboptimal rhinitis control. Participants most frequently used intranasal glucocorticoids (55.6%) and intranasal decongestants (47.4%). Only 10.3% of current nasal spray users demonstrated perfect technique. More than half (54.8%) of glucocorticoid users were identified as underadherent. Female sex, self-reported nasal hyperreactivity, active asthma, and use of oral/intranasal decongestants or nasal saline were identified as predictors of worse rhinitis control. CONCLUSION: Suboptimal rhinitis control was common in this real-life sample of persistent rhinitis patients. Improving use of rhinitis medication may be key to increase disease control.
ABSTRACT
BACKGROUND: Rhinitis medicamentosa (RM) is a type of nonallergic rhinitis caused by prolonged use of nasal decongestants (NDs). Although it is a preventable phenotype of rhinitis, little is known about patients dealing with this condition. OBJECTIVE: To gain a better understanding of patients' views and experiences of ND overuse, and potential facilitators and barriers to discontinue the overuse. METHODS: We performed a qualitative study using in-depth semistructured interviews with 22 patients who have been using an ND on an almost daily basis for at least 6 months. The interviews were conducted face-to-face, audio-recorded, and transcribed verbatim. Data analysis followed the grounded theory approach. RESULTS: Interviewees described the large impact of nasal congestion on their daily lives. Despite efforts to try other treatment options, the ND was considered the only effective aid to resolve the troublesome symptom. Most participants were aware that the prolonged use was problematic, sometimes leading to hiding behavior in order to avoid criticism by others including their health professionals. Many participants expressed a strong will to discontinue. However, multiple barriers to withdrawal were identified including fear of surgery or the impact of withdrawal on sleep, lack of good alternatives, and negative experiences with past withdrawal attempts. Patients thus face a dilemma in which the barriers to withdrawal currently outweigh the possible benefits. CONCLUSION: The use of NDs is considered indispensable by many chronic users. The facilitators and barriers identified in this study provide opportunities to reduce the use of NDs and the prevalence of RM in the future.
