I am writing to invite [Practice name] to participate as a founding partner in the inaugural trial study of the Health Horizon Conversation Tool — a new interactive clinical aid designed to transform the way clinicians and patients talk about health trajectory, longevity, and the choices that move the needle.

Standard clinical risk communication — listing risk factors, citing population statistics, advising lifestyle change — is well-intentioned but rarely produces sustained behaviour change. It tells patients what is wrong, without showing them what is possible. The Health Horizon Conversation Tool changes that.

Used collaboratively during consultations, the tool takes the patient's age, sex, health state, and a balanced set of 10 risk and 10 protective factors and generates a personalised life expectancy comparison in real time. It shows — visually, immediately, and personally — what is at stake and what is within reach.

The tool is framed around opportunity, not just risk — consistent with motivational interviewing principles. At the end of each consultation, a personalised take-home summary is printed or exported for the patient, with their numbers, their factors, and a plain-language key message from the visit.

We are running a pragmatic stepped-wedge cluster trial across 8–15 inaugural sites. The study will measure:

• Patient activation (PAM-13 score) before and after tool-assisted consultations
• Patient recall of key health messages at 48–72 hours
• Clinician-reported changes in lifestyle factor discussion depth and goal-setting
• Clinician experience, usability, and time impact

The study qualifies as a quality improvement intervention — no change to clinical treatment — and is expected to be eligible for expedited ethical review. We estimate 25–30 enrolled consultations per site over the active study period.

This trial is best suited to practices that:

• Conduct routine or preventive health consultations with adults aged 35–80
• Have 2+ clinicians willing to participate
• Can access a screen or tablet during consultations
• Are interested in patient engagement, lifestyle medicine, or preventive care research

The time commitment is modest: a 30-minute onboarding session, use of the tool in eligible consultations (estimated 3–5 minutes per use), and brief post-consultation data entry. We have designed this to be feasible within normal clinic workflows.

I am also very happy to arrange a brief call to walk you through the tool, answer any questions about the study protocol, and discuss what participation would look like for your practice specifically.
