RESULTS: At this preliminary stage we have conducted 6 focus groups with 24 asthma patients, 22 COPD patients, 43 interviews with respirologists, general practitioners, respiratory educators, policy-makers, and HL researchers to capture patients’ and professionals’ viewpoints. We have begun a systematic review of published and gray literature to elucidate the scope and deficiencies of existing tools within the context of the aforementioned domains of HL. Preliminary analysis of 10 tools shows mainly the assessment of access and understanding domains. There is a paucity in assessment of communication, evaluation and use. We identified common components of HL skills acknowledged by the three information resources. Access to understandable information, lack of communication with care providers, and comprehension of therapeutic instructions were identified as barriers to management of disease among all information sources. Patient input focused on a “lack of continuity and standardization of care” when moving between providers. Different professionals outlined the importance of encouraging self-efficacy as a method of patient empowerment to adopt the role of “self-navigator”. Policy-makers mentioned that there is a need not to just measure individuals’ abilities and skills but also to “assess what proportion of the health care system actually has HL and cultural competency built into its rules, regulations, and policies”.
