2. Definition of asthma “A chronic inflammatory disorder of the airways… in susceptible individuals, inflammatory symptoms are usually associated with widespread but variable airflow obstruction and an increase in airway response to a variety of stimuli. Obstruction is often reversible, either spontaneously or with treatment.” Thorax 2003

3. More than five million people in the UK are being treated for asthma Many emergency admissions are believed to be avoidable Many people who die from asthma had well recognised identifiable risk factors

4. British Guideline on the Management of Asthma BTS/SIGN 2008 Updated 2011

5. The aim of asthma management is disease control- this is defined as: No daytime symptoms No night-time symptoms No need for rescue medication No limitations on activity, including exercise No exacerbations Normal lung function (in practical terms FEV 1 and/or PEF <80% predicted or best) with minimal side effects from treatment

IN THE LAST WEEK / MONTH YES NO “Have you had difficulty sleeping because of your asthma symptoms (including cough)?” “Have you had your usual asthma symptoms during the day (cough, wheeze, chest tightness or breathlessness)?” “Has your asthma interfered with your usual activities (e.g. housework, work, school, etc)?” Date / / /

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

26. Quality Outcome Framework (QOF) Current QOF indicators Asthma register Annual asthma review Confirmation of diagnosis Smoking status of 14-19 year olds NO necessity to check inhaler technique or measure lung function No necessity to measure asthma control

27. What do patients care about? No bad asthma days No restriction on their life PEF is not important to patients

28. What do we care about? No chronic symptoms No asthma attacks or emergency visits Minimal need for quick relief (as needed) beta₂ agonists Patients can maintain normal physical activity, including exercise Lung function as close to normal as possible Minimal (or no) adverse effects from medicine

29. Medication £1 billion spent on respiratory drugs- not including antibiotics Respiratory items are the most expensive category in the BNF inhalers Relatively low volume of respiratory prescriptions Source: NHS information Centre

30. Inhalers Seretide (all) is the most expensive drug Seretide 250 evohaler is the most expensive individual item Symbicort 200 is the 5 th most expensive item Of the top 5 costliest drugs to the NHS, currently 3 are inhalers Source: NHS Information Centre

32. Barriers for using inhalers Sub optimal communication between HCP & patient Lack of opportunity to discuss fear of side effects Patients under-estimate the severity Over-estimate their level of control Technique

33. The most expensive inhaler is an inhaler not taken correctly Could cost 50p per puff! The right inhaler and the right technique is very important Devices such as the AIMS, in-check and 2-tone can help
