Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • poor asthma control

    2006-2009

Secondary Outcomes (1)

  • quality of care indicators (inhaled corticosteroid to beta2-agonist ratio)

    2006-2009

Study Arms (2)

1

NO INTERVENTION

Physicians in this arm will be using the standard MOXXI electronic health record.

2

EXPERIMENTAL

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

Interventions

computer-based decision support for asthma managementDEVICE

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.
