New Study Finds Use of Medicine in Asthma Patients Reduces Hospital Stay and Saves Money

Washington, DC - A new study published in the September 2015 issue of the Journal of Pediatrics found that administering dexamethasone to patients admitted for asthma exacerbation at children’s hospitals resulted in shorter hospital stays allowing for admission cost savings of eight  percent over patients who received prednisone, a commonly used steroid for asthma inpatients. Of patients administered dexamethasone, 67 percent had a length of stay of one day compared to 60 percent of patients administered prednisone. Only seven percent of the patients administered dexamethasone had a length of stay of three or more days while 12 percent of the group administered prednisone had hospitalizations of three or more days. 

The study, “Comparative Effectiveness of Dexamethasone Versus Prednisone in Children Hospitalized with Asthma,” was the first time that the two steroids commonly administered to patients with asthma exacerbations were compared for patients who were hospitalized. Prior studies have compared these steroids in an emergency department setting; however, this study focused on the use of dexamethasone for inpatients. The authors attributed dexamethasone’s impact on asthma patients’ length of stay to its longer effectiveness, palatable taste, and milder side effects. The authors also theorized that these same factors, in addition to an overall shorter course (dexamethasone is often given as a two-day course compared to prednisone which is given as a five-day course), may help in adherence to medication usage among patients who are hospitalized, potentially resulting in lower readmission rates. A two-day dosage of dexamethasone is equivalent to a five-day dosage of prednisone, which is bitter tasting and associated with vomiting as a side effect.

“Medication compliance is especially important for children hospitalized from asthma complications since these kids tend to be at risk for more readmissions due to their chronic illness, as well as environmental and socio-economic factors,” said Kavita Parikh, MD, lead author of the study from Children’s National Health System

From 2001 to 2010, the prevalence of asthma in adults and children has increased from 7.3 percent of the population in 2001 to 8.4 percent in 2010. In 2010, more than seven million children under the age of 18 were affected by asthma. While the rate of pediatric hospitalizations for asthma has declined from 165,000 in 2000 to 130,000 in 2010, the average cost per asthma-related hospital stays has remained the same at $3,600. Children from low-income communities have consistently higher rates of hospital stays for asthma than those in wealthier communities. Medicaid is the most frequent payer for children with asthma.

About the Study
The study used data from the Children’s Hospital Association’s Pediatric Health Information System (PHIS), a comparative pediatric database of clinical and resource utilization data for inpatient, ambulatory surgery, emergency department, and observation unit patient encounters for 45 children's hospitals. The study looked at children with the principal diagnosis of asthma, ages 4 to 17, who were hospitalized between Jan. 1, 2007, and Dec. 31, 2012. The study population included otherwise well patients admitted for non-severe asthma exacerbations who had mild to moderate symptoms and did not require intensive unit care. Patients who received a combination of dexamethasone and either prednisone/prednisolone were excluded from the analysis as were children with severe symptoms requiring intensive care unit admission and children with medical complexity.
