Study information

Scientific title

A multicentre, randomised trial in Ontario to evaluate the efficacy of Talking Health Together™ (THT in Practice), a communication education intervention for primary care patients with chronic disease


THT In Practice

Study hypothesis

We hypothesise that both Prepare, Ask, Check and Express (PACE) Talking Health Together™ (THT) education approaches compared to usual care will improve patient participation in medical encounters with their primary care physician. We also hypothesise that the combined THT e-Learning followed by workshop approach compared to the THT e-Learning alone approach will be more efficacious in improving patient participation in medical encounters.

Ethics approval

Institutional Review Board Services gave approval on the 9th January 2009

Type II diabetes mellitus, hypertension, hypercholesterolaemia


The three intervention arms are as follows:
1. THT e-Learning module alone
2. THT e-Learning module followed by THT nurse-led workshop
3. Control Group - wsual care (no THT intervention or other intervention)

Total duration of treatment is the length of time it takes to complete the on-line training for the e-Learning arm (approximately 45 minutes to 1 hour) and the length of time it takes to do the workshop (approximately 3 hours). For the third arm that gets usual care, there is no intervention.

Primary outcome measure

Evaluate the impact, compared to usual care, of a PACE training intervention of patients with chronic disease using one of two THT education approaches (either e-Learning only or e-Learning followed by a workshop) on patients' participation in primary care encounters assessed after intervention. We also will compare the impact of the THT e-Learning only approach to the THT e-Learning followed by workshop approach in the same way. This will be assessed by coding and analysis of audio-taped dialogue between the patient and the doctor at second of two doctor visits. Two published methodologies will be used: RIAS and MEDICODE.

Secondary outcome measures

1. Physician satisfaction with the doctor-patient encounter
2. Physician sense of partnership with patients
3. Patient perception of quality of doctor-patient communication and relationship
4. Patient confidence in own ability to communicate effectively with their doctor
5. Patient perception of the management of their chronic disease(s)
6. Patient recall of discussions of lifestyle recommendations and chronic disease medications discussed during the encounter

Assessed by questionnaires filled out by both patients and physicians at both visit 1 and visit 2.
