Background: We previously reported that not a few patients with acute severe asthma die after discharge from hospital (KJAACI 2009). This study investigated whether patient education helps to improve clinical outcomes of patients after recovery from severe asthma exacerbation or not.

Methods: Follow-up data from asthma patients who had been hospitalized due to severe exacerbation between 2007 and 2014 (Present) were compared with the previous one (1998~2006) (Previous).

Results: Age, sex, near-fatal attack, and mortality (9.8% vs. 9.6%) were not significantly different between the Previous (n=225) and Present (n=397) study. However, re-hospitalization rate was significantly lower in the Present than in the Previous study(52.4% vs. 29.3%; X2=28.0, p=0.000). The Present patients had better asthma knowledge (9.3±0.2 vs. 10.4±0.2, p=0.000) and used inhaled steroid more frequently (68.0% vs. 78.5%; X2=7.6, p=0.006). The fraction of regular hospital visitors to total subjects was significantly higher in the Present than in the Previous study (64.9% vs. 75.6%; X2=8.1, p=0.004). As the Previous study report, the regular hospital visitors (n=300) showed a significantly lower mortality (3.3% vs. 28.9%; X2=55.2, p=0.000), better knowledge (10.8±0.2 vs. 8.8±0.5, p=0.000) and higher inhaled steroid use (85.8% vs. 54.1%; X2=34.1, p=0.000) than the others (n=97) did in the Present study.

Conclusions: Clinical outcomes after recovery from severe asthma exacerbation in the present study were better than the previous one. Our efforts to educate patients might contribute to these better results.
