N2 - The following data were collected during 78 visits in 24 asthmatics newly referred to the Norwich Chest Clinic:- 1) The Hyland Living With Asthma Questionnaire (LWAQ); 2) disturbance due to asthma in sleep, work/study, & other activities in the previous four weeks, from which a total asthma score (0 no disturbance - 9 maximum disturbance) was derived, from a questionnaire completed in the clinic; 3) days off work/school, nights disturbed by asthma, usual treatment step, days treatment step was increased or prednisolone taken, days when peak flow (PF) was < 80% best (and <60% best) over the previous month, from a PF/symptoms diary; 4) clinic PF, FEV1 & FVC. 9 patients completed the LWAQ at baseline, 2 & 6 months and the total score fell (improved) from 0.87 to 0.74 & 0.75. Other changes from baseline to 6 months a) in 12 patients were:- no sleep disturbance 2 → 6; woken ≥ 1 night/week 7 → zero & b) in 13 patients:- days off work/school 2.7 → zero; nights disturbed 7.0 → 2.17; usual treatment step 3.0 → 3.92; treatment step increase 2.4 → 1.0; days prednisolone taken 5.55 → 3.23; days PF <80% best 14.2 → 7.42; days PF <60% best 2.9 → 0.15. % predicted PF in clinic rose from 76.4% to 84.5% & FEV1 from 77.6% to 81.2%. PF <80% best in the previous month was correlated with symptomatic disturbance in the previous month on 44 occasions as follows:-vs sleep disturbance P=0.066; vs work/study disturbance P=0.267; vs other activities disturbance P=0.216; vs total asthma score P=0.03. Conclusions:-These data were collected in real time in a busy clinic with no research staff. The missing values emphasise the importance of developing indices of control of asthma which can be used in such a setting. Measures which merit further evaluation in the population of asthmatics referred for specialist care include during the previous month:- days when PF fell below 80% best & nights when sleep was disturbed each recorded on a PF/symptom diary, & total asthma score derived from a self-completed questionnaire.
