Subject: Pulse pilot results — and what we are not claiming yet

Three months ago we put a small health companion in the hands of 320 patients at one clinic in Boston. We measured what we said we would measure, and only that.

Here is what we have. The companion helped users track weight, blood pressure, sleep, and activity. 78% of pilot users opened the app at least once a day, and the average session was 2.8 minutes. The clinic's care team said the first 30 seconds of a visit were the most useful; less so after that. We did not measure weight loss, doctor visits, or diagnostic accuracy in this pilot, so we are not going to claim any of those.

Here is what we are not claiming. We are not claiming Pulse detects heart disease. We are not claiming users will lose weight because of Pulse. We are not claiming fewer doctor visits. The companion surfaces patterns from the data the user puts in. The clinician decides what those patterns mean. When we do not have a study to point to, we do not claim the outcome.

We are still figuring out what the next pilot should measure. If you have run a similar pilot in your own clinic, we would like to hear what worked and what did not. Reply to this email, or book a 30-minute slot with the team using the link below.
