]. Controlling symptoms while minimising the side-effects of treatment is the main aim of asthma management. If a patient's asthma stabilises, the clinician should then consider stepping down the treatment [1]. In practice, the implementation of step-down or step-up strategies includes 1) the use of risk prediction, 2) tools to support shared decision-making and 3) communication between clinicians and patients about risk. Major contributors to poor asthma control include the following evidence-based care gaps [2]: 1) monitoring of control, resulting in the under-recognition of suboptimal control, 2) adjustment of medication, and 3) delivery of an asthma action plan. Asthma action plans, combined with asthma education and regular follow-up, can improve the symptoms and quality of life of the patient and can reduce hospitalisation [3]. However, it is difficult and time-consuming to regularly assess control in primary care. mHealth has the potential to transform the face of healthcare and one of its benefits can be to provide a clinical decision support system (CDSS). A CDSS is a health information technology system designed to assist clinicians and other health care professionals in clinical decision-making. In medicine, CDSSs have become a major topic in artificial intelligence. According to the National Academy of Medicine (Washington, DC, USA) [4], "facilitative clinical decision support is a practical necessity for every clinician in our rapidly-evolving health and healthcare landscape." A CDSS can reduce the burden that exponentially expanding clinical knowledge and care complexity places on clinicians, other healthcare professionals or patients. CDSSs provide clinicians and other health care professionals with knowledge and person-specific information, intelligently filtered or presented at appropriate times, to enhance health and healthcare. CDSSs can enhance decision-making through the use of the following tools: 1) computerised alerts and reminders to healthcare providers and patients, 2) clinical guidelines, 3) focused patient data reports and 4) diagnostic support [5]. Several self-management mHealth tools exist for asthma. Interventions such as the mobile app, the smart inhaler, the handheld asthma monitoring device, and SMSs were used to improve asthma control [6, 7].
