Brief 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.
Detailed 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.
Interventions
Pictographic depiction of medical indications alongside standard communication of these recommendations.
Standard communication by medical staff of treatment indications for asthma. An informative leaflet will be delivered as well.

Masking description
Participants, clinical investigators, outcome assessors, analysts and sponsors will be kept unaware of treatment allocation. The masking of the participating patients will be carried out through an informative brochure on bronchial asthma delivered as part of the usual education, albeit without using pictograms.
Intervention model description
Randomized clinical trial of parallel groups with triple masking amongst patients with a recent diagnosis of asthma (\<=15 days) in primary care.

Recruitment details
The first patient was recruited on August 1, 2022, and concluded prematurely, with the last patient recruited on December 20, 2022. This process was meant to be conducted for six months and had an early termination in the fifth month. Patients were recruited from 5 out of the six participating health centers. Each patient provided written consent through the signature of the informed consent form. The principal investigator and the director of the healthcare center then signed this consent.
Participants by arm
| Arm | Count |
|---|---|
| Pictogram Group This intervention consists of using a pictogram system called SIMAP which was developed and validated in previous research.
Participants allocated to this arm will received a pictographic depiction of their medical indications generated by an automated system. Information will include a description of inhaler functions, inhaler technique and correct aerochamber use.

| Usual Care Group These patients will receive their medical indications in the usual way, as established by the health team of the participating clinics. In addition, these patients will receive a bronchial asthma information leaflet as part of the usual education when explaining the disease. No pictograms will be included in these leaflets.
Usual Care: Standard communication by medical staff of treatment indications for asthma. An informative leaflet will be delivered as well. | 12 |

Outcome results
Disease Control at 30 Days
Asthma control achieved at 30 days after randomisation between groups using the Asthma Control Test (ACT).Min Score: 5 (indicating poor asthma control), Max Score 25 (indicating complete control). A score above 19 suggests well-controlled asthma.
Time frame: 30 days
Population: We recruited 10 patients, who voluntarily signed the informed consent. One patient withdrew from the study after signing the informed consent, and we lost contact with another patient during the 30-day follow-up.
