Scores of 20–25 are classified as well-controlled asthma; 16–19 as not well-controlled; and 5-15 as very poorly controlled asthma. N , total number of qualified subjects for evaluation; n (%), frequency (percentage of frequency); 95% CI, 95% confidence interval.

Maintenance therapy, medication availability and prescription during the COVID-19 pandemic

Of note, during the COVID-19 pandemic, 13.5% (24/178) of the patients had worried about insufficient maintenance medications, among whom 45.8% (11/24) had reduced medication dosing for this reason. After reducing medication dosing, 27.3% (3/11) of them experience asthma aggravation.
Among patients who had their prescriptions refilled during the COVID-19 pandemic, 60.6% (40/66) chose to go to hospitals (including community clinics, secondary and tertiary hospitals), 36.4% (24/66) chose a nearby pharmacy, and 3.0% (2/66) chose to buy online. For those who could tell the amount of medication they got in a visit(n=55), 52.7% (29/55), 21.8% (12/55), and 21.8% (12/55) had prescriptions enough for 1 month, 2 month and 3 month(or more) treatment, respectively.
For patients on maintenance therapy (n=105), 93.3% (98/105) used two or even three drugs, as illustrated in Table 4. ICS plus LABA was the most commonly used therapy, followed by ICS/LABA plus oral leukotriene modifiers (LTRA) (Table 4).
