Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Each visit is expected to take approximately 60 to 90 minutes. There are 3 visits over a period of 12 weeks with 6 weeks between visits. At each visit, participants are required to complete the Asthma Quality of Life Questionnaire, the Asthma Control Questionnaire as well as a symptom score questionnaire - these questionnaires are validated. At each visit, measurement of lung function via spirometry as well as an inhaled mannitol challenge test of airway hyperresponsiveness will be performed (Australian Register of Therapeutic Goods registration number for the mannitol challenge test = AUSTR 116832). Dependent on the results of spirometry and the inhaled mannitol challenge test, variations may be made to the dose and type of inhaled asthma medications. At Visit 2 and Visit 3, subjects who have been issued with a Smartinhaler (trademark) device to measure inhaled corticosteroid use will have the data from this device downloaded to a computer. At each visit subjects will be encouraged to remain adherent to their dose of inhaled corticosteroid and to state a personal goal for their asthma treatment.

Outcomes
Primary outcome [1] 4990 0
This is a pilot study into the feasibility and acceptability of outcome and goal orientated monitoring of inhaled corticosteroids in asthma within the general practice context using airway hyperresponsiveness challenge testing. This study is not powered to detect any outcome. The study will be used as the basis for future study designs. The number of patients who participate as well as their impressions of acceptability of the process will form the primary outcome. This pilot will assess the feasibility of implementing this method of managing asthma in general practice - this will be measured by the response rates as well as qualitative data from general practitioners and practice nurses.

Summary
Brief summary
This study aims to find out whether a method of monitoring asthma with the potential to improve adherence and control is feasible and acceptable in the general practice environment. It is hoped that this study will lead to improvements in asthma control.

Prospective asthmatic patients will be invited to participate in the study and those who meet the eligibility criteria will proceed in the study. The study will involve 3 visits of no more 2 hours duration, each visit being 6 weeks apart. There will be some flexibility in that the visits can occur 2 weekdays before or after the exact scheduled date. See Attachment 1 for the study timeline.

Subjects will be seen by Dr James Turton (study coordinator) who will conduct all clinical visits. Subjects will have their lung function tested and will be tested for asthma using an inhaled mannitol challenge test (Aridol (trademark)). During clinic visits, subjects will complete questionnaires relating to asthma quality of life, control and symptoms as well as being asked about their experiences during the testing process.

In order to measure whether the subjects are using their inhaled medication as prescribed, subjects who use “puffers” (pressurised metered dose inhaler) will be issued with an electronic dose counter (Smartinhaler (trademark)). The Smartinhaler (trademark) device will time and date stamp each actuation – subjects will be informed of this feature of the device. Those who use an alternative dry powder inhaler type of medication will have the built-in dose counter on such devices checked at each visit.

As this is a feasibility and acceptability study, both general practitioners and practice nurses will be invited to give their impressions of the monitoring process in brief semistructured interviews.

The information obtained in the pilot study will inform the development of a formal research protocol to test this intervention.
