Status Recruiting

Clinical Trial Summary

SIMAP is a triple-masked randomised trial aimed at assessing whether an automated system of pictograms associated to medical indications results in better comprehension and adherence of said indications. Adult patients with a recent diagnosis of asthma will be randomised to receive a pictographic depiction of their treatments and recommended interventions or standard communication without assistance from their attending physician. Patients will be followed-up for 60 days using the Asthma Control Questionnaire (ACT). The primary endpoint of this study is the degree of asthma control as assessed by the aforementioned questionnaire. Secondary outcomes include the number of hospitalisations, emergency care unit visits and the need to increase bronchodilator therapy as per current Global Initiative for Asthma guidelines. Outcomes will be analysed under the intention-to-treat principle by a statistician unaware of treatment allocation.

Clinical Trial Description

In this triple-masked randomised trial, adult participants with a recent diagnosis of asthma (<15 days) will be allocated to receive a pictographic depiction of their medical indications or a standard description of said indications. Eligible patients will include those between 18 and 65 years of age with a diagnosis of asthma established by standard clinical recommendations (clinical and spirometric criteria as established by Global Initiative for Asthma - GINA - guidelines) and in whom therapy including a bronchodilator and a controller medication (typically an inhaled steroid) is planned to be initiated. Patients with another cause of bronchial obstruction (such as COPD), those with cognitive or visual impairments that hampers the understanding of pictograms or those with a history of alcoholism or alcohol abuse will be excluded. Patients will be randomised using a permuted block sequence which shall be kept hidden from other investigators. Participants will be followed-up at seven, thirty and sixty-day intervals using the Asthma Control Questionnaire (ACT), which is the primary outcome of this study. Participants, clinical evaluators, analysts and sponsors will be kept unaware of treatment allocation. Secondary endpoints include the inhaler technique, the correct depiction of inhaler medication purpose, the rate of emergency care visits between groups, the rate of hospitalisations between groups and the need to increase bronchodilator therapy during scheduled visits within the trial. All analyses will be conducted using the intention-to-treat principle. ;
