Impact of azelastine nasal spray on symptoms and quality of life compared with cetirizine oral tablets in patients with seasonal allergic rhinitis.

BACKGROUND: In fall 2004, the first Azelastine Cetirizine Trial demonstrated statistically significant improvements in the total nasal symptom score (TNSS) and Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ) scores with the use of azelastine nasal spray vs oral cetirizine in patients with seasonal allergic rhinitis (SAR). OBJECTIVE: To compare the effects of azelastine nasal spray vs cetirizine on the TNSS and RQLQ scores in patients with SAR. METHODS: This 2-week, double-blind, multicenter trial randomized 360 patients with moderate-to-severe SAR to azelastine, 2 sprays per nostril twice daily, or cetirizine, 10-mg tablets once daily. The primary efficacy variable was the 12-hour reflective TNSS (rhinorrhea, sneezing, itchy nose, and nasal congestion). Secondary efficacy variables were individual symptom scores and the RQLQ score. RESULTS: Azelastine nasal spray and cetirizine significantly improved the TNSS and individual symptoms compared with baseline (P < .001). The TNSS improved by a mean of 4.6 (23.9%) with azelastine nasal spray compared with 3.9 (19.6%) with cetirizine. Significant differences favoring azelastine nasal spray were seen for the individual symptoms of sneezing and nasal congestion. Improvements in the RQLQ overall (P = .002) and individual domain (P < or = .02) scores were greater with azelastine nasal spray. Both treatments were well tolerated. CONCLUSIONS: Azelastine nasal spray and cetirizine effectively treated nasal symptoms in patients with SAR. Improvements in the TNSS and individual symptoms favored azelastine over cetirizine, with significant differences for nasal congestion and sneezing. Azelastine nasal spray significantly improved the RQLQ overall and domain scores compared with cetirizine.

Willingness to pay for sensory attributes of intranasal corticosteroids among patients with allergic rhinitis.

OBJECTIVE: Sensory attributes of intranasal corticosteroids (INSs) differ by product based on chemical composition. We previously reported that patients are able to demonstrate preferences for certain INS sensory attributes, which may affect their willingness to adhere to therapy. As part of the same study, we also sought to determine if these same patients are willing to pay for products not containing certain sensory attributes. METHODS: We conducted a 2-part cross-sectional study of 120 patients with allergic rhinitis at 4 allergy and immunology clinics in the United States in November and December 2003. In the first part of the study, the patients chose between pairs of hypothetical INS products that differed in the intensity of 6 sensory attributes (smell, taste, aftertaste, throat rundown, nose runout, and feel of spray in nose/throat; results were reported in the Annals of Allergy, Asthma & Immunology [2004;93:345-50]). In the second part of the study, reported here, discrete choice experiment methodology was used in which the patients chose among hypothetical INS products that differed in the intensity of the 6 sensory attributes and monthly copayments of dollar 15, dollar 30, and dollar 50. Each sensory attribute was characterized by 3 intensity levels, e.g., no aftertaste (mild intensity), weak aftertaste (moderate intensity), or strong aftertaste (severe intensity). The strength of preferences, shown as marginal willingness to pay to avoid certain sensory attributes, was measured in U.S. dollars per month. We also evaluated the effect of annual household income on willingness to pay. RESULTS: Demographic results indicated that 86.7% of participants had prior experience with at least 2 INS products. Seven patients (5.8%) were excluded from the willingness-to-pay analysis due to inconsistent responses to the logic checks used to confirm patient engagement in the study instrument. On average, the 113 remaining patients were willing to pay $11 (95% confidence interval [CI], dollar 9-dollar 13) per month in 2003 dollars to get an INS with no smell instead of strong smell, dollar 12 (95% CI, dollar 10-dollar 14) for no taste instead of strong taste, dollar 20 (95% CI, dollar 18-dollar 22) for no aftertaste instead of strong aftertaste, dollar 10 (95% CI, dollar 9-dollar 12) for no throat rundown instead of a lot of throat rundown, dollar 11 (95% CI, dollar 9-dollar 13) for no nose runout instead of a lot of nose runout, and dollar 6 (95% CI, dolalr 4-dollar 8) for a spray with a wet feel instead of a dry feel. Comparing moderate intensity levels of each sensory attribute with the mildest, only 3 attributes had statistically significant willingness to pay: aftertaste, throat rundown, and nose runout. Patients with a higher income were willing to pay more to avoid a lot of throat rundown and nose runout than those with a low income (P <0.01), but this relationship did not hold for the other sensory attributes. CONCLUSION: Patients demonstrated significant willingness to pay to avoid certain sensory attributes of INSs. Sensory attributes of INS products appear to be potentially important considerations when evaluating alternative INS products for drug therapy selection or formulary placement.

The maternal-fetal medicine fellowship match system: effectiveness at identifying successful clinician-investigators at 1 institution.

OBJECTIVE: To determine if rank position on the match list of a maternal-fetal medicine (MFM) fellowship program predicted applicant academic success. STUDY DESIGN: The Thomas Jefferson University MFM fellowship program rank order lists and the results of the match were reviewed for 1991-2002. Evaluation of candidates includes an application, 3 letters of recommendation, curriculum vitae and interview upon invitation. Career success of graduated fellows was defined as MFM board certification, number of peer-reviewed publications and of Society for MFM (SMFM) abstract publications. RESULTS: Applicants ranked higher tended to have more peer-reviewed publications per applicant (9.2 vs. 4.7 vs. 4.4, p = 0.5) and more abstracts presented at SMFM (7.6 vs. 8.0 vs. 3.8 p = 0.5) as compared to lower-ranked applicants. Ranked applicants had a higher probability of being MFM board certified (74 vs. 22%, p = 0.005), having more peer-reviewed publications (6.8 vs. 1.4, p = 0.005), and more abstracts (7.1 vs. 2.1, p < 0.0001) as compared to nonranked applicants. CONCLUSION: MFM fellowship applicants who were ranked higher were more likely to publish as compared to lower-ranked applicants. Ranked applicants were more likely to publish and be MFM board certified as compared to nonranked applicants.

Patient preferences for sensory attributes of intranasal corticosteroids and willingness to adhere to prescribed therapy for allergic rhinitis: a conjoint analysis.

BACKGROUND: Sensory attributes of intranasal corticosteroid (INS) products vary. OBJECTIVE: To evaluate patient preferences for INS sensory attributes and the degree to which attributes influence patients' willingness to adhere to therapy. METHODS: We conducted a cross-sectional study with 120 individuals across 4 US allergy/immunology clinics. Respondents chose between pairs of hypothetical INSs differing in sensory attribute composition. We measured the strength of preferences for 6 sensory attributes (smell, taste, aftertaste, throat rundown, nose runout, and feel of spray in nose or throat). Preferences were measured for 3 intensity levels of each sensory attribute (eg, no taste, weak taste, and strong taste). Other outcomes included an importance score for each sensory attribute and patients' willingness to adhere to therapy with an INS with the lowest intensity levels of each sensory attribute vs one with moderate intensity levels. RESULTS: Preferences decreased with increasing intensity levels of each sensory attribute. Aftertaste was the most important attribute in 28% of patients, taste in 19%, throat rundown in 18%, nose runout in 12%, smell in 11%, and feel of spray in 7%. If instructed to take an INS daily for 3 months, 77% of patients stated that they would definitely be able to follow their physician's advice (willingness to adhere) if given one containing the lowest level of each sensory attribute vs 4% if given one having moderate levels (P < .01). CONCLUSIONS: Patient preferences are inversely related to increasing intensity levels of sensory attributes and affect patients' willingness to adhere to therapy. Application of patient preferences when selecting INSs could improve adherence.
