Brief summary
The goal of this randomized clinical trial is to learn about the impact of the implementation of an intervention-based case management follow-up program during periods of clinical worsening or poor adherence in patients with moderate and severe asthma. Patients will be randomized into two arms: a case management follow-up group and a control group that will follow-up according to routine care practice. A single masking (outcomes assessor) was performed. Researchers will compare the response on exacerbations, health resource use and asthma control between the two groups during a one-year follow-up. Outcomes on pulmonary function, quality of life, adherence to treatment, pulmonary inflammation parameters and systemic corticosteroid use will also be studied. Additionally, other baseline clinical characteristics and events of the previous year will be collected retrospectively for all patients. The study was evaluated and approved by a local ethics committee. All study participants will receive an asthma education session with review of inhaler technique and training in the use of self-management action plans. Only participants in the case management follow-up group will periodically send asthma control (ACT) and adherence (TAI) questionnaires to the case manager. If not completed, the case manager will contact the patient by telephone to determine the degree of asthma control and adherence. The case manager will also monitor the withdrawal of drugs on the electronic prescription. The patient will contact the case manager via a mobile app, phone or email if needed due to worsening symptoms or need for self-management support. With this information, the case manager will make decisions based on personalized medical instructions prepared by the pulmonologist at the baseline visit, which will be reviewed according to evolution.
Interventions
The case manager will monitor asthma control (asthma control test, ACT) and adherence to treatment with questionnaires (inhaler adherence test, TAI) and electronic prescription withdrawal (e-prescription). The case manager will make decisions based on these results and according to pre-designed medical instructions. In addition, the patient will be able to contact the case manager for advice during periods of worsening symptoms. The patient will contact the case manager via a mobile app with messaging and video call option, as well as a contact phone number and email for consultations.

Eligibility
Inclusion criteria
* Age ≥ 18 years. * Previous diagnosis of bronchial asthma according to GEMA 5.4 criteria. • Follow-up for at least 6 months in an asthma unit and absence of relevant uncontrolled comorbidities. * Classified as moderate or severe asthma according to therapeutic step at the beginning of the study, as defined by GEMA 5.4. * Signed informed consent form.
Exclusion criteria
* Simultaneous presence of other diseases that may simulate asthma symptoms (COPD, left heart failure, functional dyspnea/hyperventilation syndrome, inducible laryngeal obstruction...). * Severe psychosocial problems or any other clinical situation that prevents the signature of the informed consent and/or the follow-up proposed in the study. * Lack of minimum technological knowledge for the use of monitoring tools.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Median ACT score at 6 and 12 months compared with control group and baseline | At 6 and 12 months | ACT is a validated, self-administered questionnaire to assess asthma control in the last 4 weeks. Possible scores range from 5 (worst possible control) to 25 (best possible control). Scores equal to or greater than 20 suggest good asthma control. Median ACT score at 6 and 12 months compared with control group and baseline |
| Median of total and severe exacerbations at 12 months | From baseline to 12 months | Hospital admissions, emergency room visits, and unscheduled medical visits for asthma exacerbation accumulated at the end of the follow-up period compared with control group and baseline |
| Median healthcare resources use at 12 months | From baseline to 12 months | Healthcare resource use was defined as the addition of the number of unscheduled medical visits in primary care, emergency department care and hospitalisations. Median use of health resources at 12 months compared with control group and baseline |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Median FeNO value at 6 and 12 months | At 6 and 12 months | Exhaled nitric oxide (FeNO) will be measured using NioxVero electrochemical analyser according to standard use technique. FeNO is measured in ppb. Median FeNO value at 6 and 12 months compared with control group and baseline. |
| Median of electronic prescription withdrawal at 12 months | At 12 months | To assess adherence, the percentage of withdrawal of inhaled glucocorticoid e-prescriptions will be measured. |
| Median blood eosinophil count at 12 months | At 12 months | Median blood eosinophil count at 12 months compared with control group and baseline. |
| Median pre-bronchodilator forced expiratory volume in the first second (pre-bronchodilator FEV1) and zscore at 6 and 12 months | At 6 and 12 months | Lung function was measured according to the SEPAR guidelines. Zscore is a tool to express results of spirometry that facilitates interpretation and comparison between patients with different characteristics. The Z-score indicates how many standard deviations a measured value is from predicted. Median pre-bronchodilator forced expiratory volume in the first second (pre-bronchodilator FEV1) and zscore at 6 and 12 months compared with control group and baseline |
| Median AQLQ score at 6 and 12 months | At 6 and 12 months | Asthma Quality of Life Questionnaire (AQLQ) is a validated, self-administered questionnaire to assess quality of life related to asthma. Possible scores range from 1 (worst possible quality of life) to 7 (best possible). The minimum clinically significant change is 0.5 points. Median AQLQ score at 6 and 12 months compared with control group and baseline. |
