IN THE LAST WEEK / MONTH<br />
“Have you had difficulty sleeping because of your asthma<br />
symptoms (including cough)?”<br />
“Have you had your usual asthma symptoms during the day<br />
(cough, wheeze, chest tightness or breathlessness)?”<br />

Asthma Control Test (ACT)<br />
1. In the past 4 weeks, how much of the time did your asthma keep you from<br />
getting as much done at work, school or at home?<br />
Score<br />
2. During the past 4 weeks, how often have you had shortness<br />
of breath?<br />
3. During the past 4 weeks, how often did your asthma symptoms<br />
(wheezing, coughing, shortness of breath, chest tightness or pain)<br />
wake you up at night, or earlier than usual in the morning?<br />
4. During the past 4 weeks, how often have you used your rescue<br />
inhaler or nebulizer medication (such as salbutamol)?<br />
5. How would you rate your asthma control during the past<br />
4 weeks?<br />

Rhinitis frequently under‐diagnosed and<br />
misdiagnosed in practice<br />
Simple tools to support diagnosis<br />
Rhinitis frequently poorly assessed<br />
Tools to assess impact in clinical practice as opposed<br />
to clinical trials not fully developed but rapid<br />
development in this area<br />
Need to ensure link to assessment of asthma as<br />
rhinitis severity important predictor of future risk in<br />
patients with asthma
