Physicians of London three questions<br />

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 />

“Has your asthma interfered with your usual activities<br />

(e.g. housework, work, school, etc)?”<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
