PURPOSE: To study the trend of asthma exacerbation readmission rates over the last several years.

METHODS: We evaluated the readmission rates for asthma over the last several years to observe the trend of asthma readmissions to the hospital within 30 days of discharge. We present the trends during the time period 2009 to 2013 using data from Healthcare Cost and Utilization Project Nationwide Readmissions Database. A cohort of 1,220,047 asthma hospitalizations of patients older than 18 years was identified in this time period and the 30-day readmission rates were analyzed by comparing rates in consecutive years and the beginning and end of the time period listed using Z-test for proportions.

RESULTS: The subsequent hospital readmission rates with asthma as the primary diagnosis within 30 days following an original asthma admission were the following through the years 2009-2013: 5.1% (13,672/267,211), 5.4% (13,669/252,460), 5.3% (12,918/243,475), 5.1% (11,902/229,630), 5.1% (11,572/227,272). When comparing rates in consecutive years the trend through the aforementioned years was not statistically significant (p>0.05) suggesting that there has been no significant change in asthma readmission rates between 2009 and 2013.

CONCLUSIONS: Asthma continues to be one of the leading causes of hospital admissions in the United States with a total of 1,220,047 admissions between 2009 and 2013. With a consistently 30-day readmission rate of more than 5% there has been no significant change in asthma readmission rates between 2009 and 2013.

CLINICAL IMPLICATIONS: Asthma related conditions are considered ambulatory care sensitive conditions that could have been avoided, through better education and outpatient care. A previous study in pediatrics asthma showed that post-discharge outpatient follow up in addition to proper education was associated with reduced hospital readmission rates, similar studies evaluated other diseases in adults including COPD were suggestive of decreasing readmission rate with better education and outpatient follow up, but we could not find well established studies to evaluate how these measures can affect readmission rates of asthma in adults. As the readmission rates of asthma have been stable over the last few years, more studies need to evaluate the effect of optimizing discharge medications, asthma education and post-discharge follow up on readmission rates.
