Brief summary
GeoAsma is a study for the definition, validation and evaluation of predictive models on the influence of the environment on asthmatic patients in Andalusia.
Detailed description
Although for decades there have been multiple studies on the association of asthma with factors such as weather conditions, pollution, pollen and the social condition of patients, the GeoAsma project aims to advance the study of environmental factors that influence the health of asthmatic patients by combining BigData technology and data mining analysis, Geographic Information Systems and open data provided by official sources with data from the Electronic Health Record of the Andalusian Health System, that provides healthcare services to more than 8,000,000 citizens. This project aims to study through data mining techniques and multilevel analysis the influence of clinical and environmental factors: pollen level, air pollution, atmospheric conditions and social determinants in more than 800,000 asthmatic patients during the last 15 years in Andalusia, the southernmost region of Spain. It is expected that the results of this study will serve to define predictive models that will help professionals and patients in our region to make decisions. After the validation of the models, a decision support system will be implemented in a web platform and in a mobile application. Its impact on the reduction of exacerbations, control, quality of life and resource consumption of asthmatic patients will be analysed. This evaluation will be carried out through a pilot with 214 patients with a follow-up period of 12 months with asthma in the hospitals participating in this proposal.
Interventions
OTHERClinical Decission support system management & mobile App Intervention Group
The clinicians treating the patients will use a clinical decision support system that includes predictive models associated with the level of risk of exacerbation. This models have been obtained in asthmatic patients by applying data mining techniques and multilevel analysis in the study of the influence of clinical characteristics and the environment of each subject. The patients will use a mobile app to help manage their symptoms.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Treatment adherence | 1 year | Estimated through dispensations |
| Asthma control | 1 year | The Asthma Control Test is a validated determination of asthma control that is directly control of asthma that is answered directly by the patient and consists of five questions questions that assess: activity limitations, dyspnea, nocturnal symptoms, rescue medication use, and the patient's overall rating of asthma control. symptoms, use of rescue medication, and the patient's overall rating of asthma control over the previous four weeks, which is defined from the results of a questionnaire. |
| Number of exacerbations Number of exacerbations | 1 year | Measured by the number of times the patient goes to the emergency room or uses rescue medication and/or cycles of oral corticosteroids. |
| Health-related quality of life | 1 year | The Asthma Quality of Life Questionnaire (AQLQ) will be administered at baseline, 3 and 6 months of the study. The AQLQ contains 32 items corresponding to 4 dimensions of health: limitation of usual activities, symptoms, emotional function, and environmental stimuli. |
| Quality-adjusted life year | 1 year | To calculate this index, the EuroQol-5D quality of life questionnaire will be administered at baseline, three and six months into the study. The EQ-5D describes health status with five dimensions (mobility, self-care, activities of daily living, pain/discomfort, and anxiety/depression), each of which is defined with three levels of severity. It also consists of a millimetered Visual Analog Scale (VAS) on which the subject must score his or her health status on the day of the survey, with the extremes of the scale being the worst imaginable health status (0) and the best imaginable health status (100). |
| Patient satisfaction | 1 year | It will be carried out at the end of the study by means of a questionnaire that includes items on ease of use, usefulness, intention to use, etc. |
| Respiratory function | 1 year | Several pulmonary function tests will be carried out. These tests will include spirometry (FEV1, FVC, FEV1/FVC ratio, PC20, PD15, Fractional exhaled nitric oxide) |
| Immune response | 1 year | IgE test, lymphocite count |
