Individualized electronic decision support and reminders to improve diabetes care in the community: COMPETE II randomized trial

Background: Diabetes mellitus is a complex disease with serious complications. Electronic decision support, providing information that is shared and discussed by both patient and physician, encourages timely interventions and may improve the management of this chronic disease. However, it has rarely been tested in community-based primary care. Methods: In this pragmatic randomized trial, we randomly assigned adult primary care patients with type 2 diabetes to receive the intervention or usual care. The intervention involved shared access by the primary care provider and the patient to a Web-based, colour-coded diabetes tracker, which provided sequential monitoring values for 13 diabetes risk factors, their respective targets and brief, prioritized messages of advice. The primary outcome measure was a process composite score. Secondary outcomes included clinical composite scores, quality of life, continuity of care and usability. The outcome assessors were blinded to each patient’s intervention status. Results: We recruited sequentially 46 primary care providers and then 511 of their patients (mean age 60.7 [standard deviation 12.5] years). Mean follow-up was 5.9 months. The process composite score was significantly better for patients in the intervention group than for control patients (difference 1.27, 95% confidence interval [CI] 0.79–1.75, p < 0.001); 61.7% (156/253) of patients in the intervention group, compared with 42.6% (110/258) of control patients, showed improvement (difference 19.1%, p < 0.001). The clinical composite score also had significantly more variables with improvement for the intervention group (0.59, 95% CI 0.09–1.10, p = 0.02), including significantly greater declines in blood pressure (−3.95 mm Hg systolic and −2.38 mm Hg diastolic) and glycated hemoglobin (−0.2%). Patients in the intervention group reported greater satisfaction with their diabetes care. Interpretation: A shared electronic decision-support system to support the primary care of diabetes improved the process of care and some clinical markers of the quality of diabetes care.

Patients' consent preferences regarding the use of their health information for research purposes: a qualitative study:

Objective: To explore the consent preferences of patients whose health data are currently being used for research purposes. Methods: Semi-structured interviews were conducted with 17 patients whose primary physicians were taking part in a study that utilized de-identified individual-level health information from their electronic medical record. All physicians practised in southwestern Ontario. All interviews were taped, transcribed verbatim and analysed using a constant comparative method. All transcripts and debriefing notes were read and reread to elicit general themes. Results: Three main themes emerged from the data: patients recognized the need to balance their consent preferences with time pressures in the clinical encounter when deciding the nature of consent for a study; patients generally regarded the seeking of consent as being an issue of respect for them as individuals; and patients were also weighing their perceived benefits and concerns related to the research. For these patients, seeking their consent was an important step in research participation. For some patients, the sponsor and the research topic were factors that would influence their decision to provide consent. Conclusion: Patients want their consent to be sought when their data are used for research purposes. This will involve explicitly informing patients that a study is taking place, providing written consent and offering regular updates about the study.
