This is a health services demonstration project that evaluates three methods of health care delivery for the management of individuals with symptoms of asthma. This study will evaluate the impact of a telephonic asthma disease management process, with and without a home intervention program, on preventing asthma-related morbidity through patient/family asthma education.

The investigators'''' central thesis is that comprehensive clinical disease management protocols for the management of asthma will improve clinical outcomes; reduce fiscal resource consumption; and improve both patient satisfaction and patient quality of life. Additionally, individualized, in-home patient education and environmental assessment, when added to the telephonic protocol, will further improve these measures. However, incremental improvement will vary according to the population''''s access to care.

This trial addresses the real-world concerns of asthma management through a disease management approach that will assist both the patient and the primary care physician by providing education, additional outpatient resources and additional access to health care personnel. This approach will stress empowering the patient to participate in his or her own health care at a higher level, which, in the case of asthma, is critical to wellness.

In a cooperative network of San Antonio medical centers, civilian and military, with a collective mission to care for military beneficiaries and the underserved patients of South Texas, this trial will evaluate the clinical benefits, as well as the cost savings, of a chronic disease management intervention in asthma. This study will fill a conspicuous gap in the medical literature by addressing the effectiveness of disease management through a large, decentralized, randomized, controlled trial.


The project will use asthma disease management protocols and educational materials developed by the National Jewish Medical and Research Center. The program will be fully available in both English and Spanish, allowing a direct test of its impact on the State’s vulnerable Hispanic population. Based on the principles of comprehensive disease management, National Jewish Medical and Research Center has developed a disease management program for asthma (DMP: Asthma) which addresses continuity of care by integrating traditional treatment methods with a program that focuses on creating a stronger partnership between the patient and the healthcare team, as well as greater patient empowerment. The primary program goal is empowering patients with the tools and resources they need for better self management of their prescribed treatment regimens and control of their environment. The program incorporates practice guidelines outlined by the National Heart, Lung, and Blood Institute (NHLBI) at the National Institutes of Health (NIH).


In addition, the demonstration will evaluate the addition of a home-based disease management protocol focusing on patient education, to test for incremental improvement. Patients will be taught about their disease (symptoms, treatment, appropriate action plans), as well as about the healthcare system (how and when to access it). Based on the principles of comprehensive disease management and the unique needs of South Texas residents, the South Texas Asthma Management Program (STAMP) is designed for a diverse, mobile, underserved patient population. The protocol delivers up-front home-based education and environmental assessment, with follow-up visits focused on reinforcement of the earlier messages. The program ensures access to a primary care provider for patients who lack this critical member of the healthcare team. It also provides multiple resources for social services and guidance in appropriately accessing the healthcare system. The goal of the program is to equip patients, who have barriers to access due to a number of factors (lack of phone, language, remote location, etc), to navigate the healthcare system and effectively receive the care they need.
