N. Ricard et al., Link between patient preferences and treatment outcomes in seasonal allergic rhinitis: An empiric investigation, CLIN THER, 21(1), 1999, pp. 268-277
In a multicenter, parallel-group, double-masked, randomized study, two ques
tionnaires were administered to a clinical study population to identify whi
ch specific symptoms of seasonal allergic rhinitis patients perceived as mo
st important to relieve (personal preferences) and to learn whether any rel
ationship existed between patient preferences and the severity of their sym
ptoms during treatment with antihistamines. The group was composed of 256 m
ales and 313 females. Their mean age was 32.4 years, and mean duration of s
easonal allergic rhinitis was 14.5 years, with mean age of onset of 17.7 ye
ars. After receiving placebo for I week, patients were randomly allocated t
o receive an antihistamine (fexofenadine or loratadine) for 2 weeks. Patien
t preferences for relief of individual allergy symptoms (rhinitis; sneezing
; itchy, watery, red eyes; itchy nose, palate, or throat) and related condi
tions (fatigue, physical limitations) were scored using 2 different questio
nnaires before treatment (0-to-10 category rating scale far assessing the 4
symptoms of allergic rhinitis) and after receiving placebo for 1 week (Fee
ling Thermometer). Symptom severity was reported in patient diaries after 1
and 2 weeks of antihistamine treatment and was measured by patient self-as
sessment. All symptoms were considered by the patients to be important to r
elieve, the most important being itchy, watery, red eyes and rhinorrhea. Th
e severity of allergy symptoms was consistently related to the importance o
f symptoms identified before treatment. Therefore, including patient prefer
ences in medical evaluations might be a useful tool in evaluating the succe
ss of their treatment.
