The most common asthma medication used by the participants was short acting beta agonist (SABA) which was reported by 93% (n=27) of the sample, followed by oral corticosteroids (48%, n=14) and combination of Inhaled corticosteroids (ICS) and Long-acting Beta Agonists (LABA) (45%, n=13). Use of Leukotriene Antagonists and ICS was reported by five participants, each. In addition, fewer reported anti-cholinergics (7%, n=2), and none reported use of LABA alone (e.g., Salmeterol). No significant gender differences were found in medication use. We compared the self-reported medications with those listed in the medical records to assess discrepancies. Medical records were unavailable for two participants whom we did not include in calculating the following percentages. Of twenty- seven participants, twelve (44%) reported no use of ICSs or an ICS/LABA combination in their diaries. However, medical records revealed that five of those actually had prescriptions for an ICS or an ICS/LABA combination, yet failed to report these in their diaries. Table 3 compares the number of participants reporting medications of each type in the diaries and medical records, and provides percent agreement. The highest agreement was found in SABA (89%) followed by the ICS/LABA combination (73%) and systemic steroids (58%). Anti-cholinergics were the most commonly omitted medications from the participants’ diaries, followed by Leukotriene Antagonists. Of twelve participants with anti-cholinergic prescriptions, only two reported taking the medication in their diaries. Of a total of 43 discrepancies in all types of medications reported in Table 3, 91% occurred due to participants’ under-reporting of medications in the diaries. Only 9% of discrepancies were due to participants reporting of medications that were not validated by the medical records.
