Asthma is a health problem that afflicts many Canadians. Better methods are needed to provide primary care physicians with ways of implementing current guidelines into regular practice for optimal disease management. This study will test the benefits of providing computer-based decision-support for asthma to primary care physicians, with links to home monitoring for their patients. To add value and to ensure regular use for the physician for all of his/her patients, these computerized decision-support tools will be linked to an electronic prescribing and drug management system. The investigators will evaluate the effectiveness of the computer-based decision-support system by determining whether asthma patients of physicians who receive computer-assisted management tools have better disease control after 33 months of implementation compared to asthma patients of physicians who have the electronic prescription and drug management system alone. To answer this question, the investigators will conduct a cluster randomized controlled trial in a population of approximately 100 physicians in 40 clinics in Quebec, and a total of approximately 4500 of their patients with asthma.

Further study details as provided by Robyn Tamblyn, McGill University:

Primary Outcome Measures:
  • poor asthma control [ Time Frame: 2006-2009 ]

Secondary Outcome Measures:
  • quality of care indicators (inhaled corticosteroid to beta2-agonist ratio) [ Time Frame: 2006-2009 ]

Enrollment: 4447
Study Start Date: October 2006
Study Completion Date: June 2009
Primary Completion Date: June 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
No Intervention: 1
Physicians in this arm will be using the standard MOXXI electronic health record.
Experimental: 2
In addition to the standard MOXXI electronic health record, physicians in this arm will be using the computer-based decision support for asthma management
Device: computer-based decision support for asthma management
The asthma management decision support system uses data from the patient problem and medication list to provide patient-specific management recommendations based on Canadian Consensus guidelines for asthma management. Web-enabled technology for asthma education nurses is used to collect home-monitoring information from patients between visits and feedback to primary care physicians in accordance with options selected by the physician for each patient.
