Researchers at the University of Texas Health Science Center at San Antonio conducted a study from 1999 to 2004 titled "A Randomized, Controlled Study to Evaluate the Role of an In-Home Asthma Disease Management Program Provided by Respiratory Therapists in Improving Outcomes and Reducing Cost of Care." The primary objective of this study was to determine if an in-home asthma disease management program provided by respiratory therapists (RT) could improve patient outcomes and reduce the cost of care when compared to home care provided by nurses (RN) or standard care provided in the physician's office.

Eligible patients, 18-64 years who received ED or inpatient treatment for an asthma exacerbation, were randomized upon discharge to a standard care group, a group receiving post-discharge home health visits from RNs, or a respiratory care asthma disease management intervention program group receiving post-discharge home visits from RTs. The three groups were followed prospectively in a blinded fashion for six months.

Positive outcomes were as follows: emergency department visits, physician office visits (sick/unscheduled), quality of life, and symptoms.
