Computer-Based Decision Support in Managing Asthma in Primary Care
This study is currently recruiting participants.

First Received: September 13, 2005   Last Updated: January 21, 2009   History of Changes

Collaborator: Canadian Institutes of Health Research (CIHR)

ClinicalTrials.gov Identifier: NCT00170248
  Purpose

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 18 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 2,880 of their patients with asthma.

Primary Outcome Measures:
  • poor asthma control [ Time Frame: 2005-2009 ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • quality of care indicators (inhaled corticosteroid to beta2-agonist ratio, prescription of an action plan) [ Time Frame: 2005-2009 ] [ Designated as safety issue: No ]
  • patient outcome:self-reported symptom control [ Time Frame: 2005-2009 ] [ Designated as safety issue: No ]

Estimated Enrollment: 2880
Study Start Date: March 2003
Estimated Study Completion Date: September 2009
Estimated Primary Completion Date: September 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
1: No Intervention
Physicians in this arm will be using the standard electronic prescription interface.
2: Experimental
In addition to the standard electronic prescription module, 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.
