Parental Perceptions and Preferences of Asthma Medication Delivery Devices in a Pediatric Emergency Room Público

Abstract

Many children in the United States suffer from asthma, which is a common chronic lung disease characterized by airway inflammation and swelling. Typical symptoms include coughing, wheezing, shortness of breath, and sputum production. While patients and families can treat symptoms of asthma at home, there are numerous incidents in which parents bring asthmatic children to emergency departments for medical treatment.

Children’s National is one such hospital that treats children with asthma. The hospital is a world-renowned pediatric hospital located in the center of Washington, D.C. It is also the only pediatric level I trauma center in the nation’s capital, making it a premiere center to treat sick patients. Children’s National uses the short acting bronchodilator albuterol to treat children who come to the emergency department experiencing asthma attacks.   

Albuterol is typically administered either through a nebulizer or a metered dose inhaler with spacer (MDI+S). Both devices have been extensively studied to compare their efficacy in treating asthma. Studies have determined that the MDI+S is as effective as the nebulizer is at treating acute asthma exacerbations in pediatric emergency rooms. Additionally, the MDI+S cuts down time spent in the emergency department for patients. Thus, physicians at Children’s National have been attempting to treat children with albuterol via an MDI+S. However, some doctors have been met with parental resistance to this treatment plan.

Determining whether parents prefer the nebulizer or MDI+S and why is critical for understanding the treatment perceptions and preferences of parents. The culture of American biomedicine has swayed towards emphasizing the preferences and decisions of physicians. However, patient care in emergency departments will hopefully be improved upon by developing treatment plans in accordance with the preferences of not only the physicians but also patients and their families.

A sample of parents visiting the emergency department at Children’s National completed a survey inquiring into their perceptions and preferences of asthma medication delivery devices.  The responses from this research project conducted at Children’s National were used to explore parental perceptions as they relate to device ease, speed, comfort, and effectiveness.
