People with limited health literacy | We defined intervention as one that included people with limited health literacy quantitatively and using evidence-based approaches. Quantitatively, study populations that measured health literacy level using validated tools and included ≥40% of people with limited health literacy in the trial are included. We will include study populations that include individuals with high risk of limited health literacy through publications of evidence in systematic review reports and qualitative studies. This will include the following: 1) Immigrants 2) Ethnic minorities 3) Illiterates |
Types of interventions (1) Self-management | We will include any asthma-self management interventions within the taxonomy of the self-management support components suggested by Taylor et al.3. a) Direct components (delivered directly to patients and/or carers) such as education, action plans and practical support with adherence. b) Indirect components: healthcare or social care at a professional level (delivered to individual healthcare professionals or social care professionals) such as equipment, feedback and review. c) Indirect components: delivered at an organisational level such as prompts using paper or electronic reminders. |
(2) Addressing health literacy | We will included any interventional designs that are aimed at improving health literacy, as suggested by Sheridan et al.20: a) Presenting written information differently (e.g. essential information first) b) Presenting numerical information differently (e.g. the highest number is better) c) Using icons, symbols and graphs d) Presenting information pitched at a lower literacy level (e.g. primary school comprehension) e) Use of videos f) Literacy training for patients and physicians g) Implementing comprehension skills to enable self-care |
