Thanks! Digital health can be incredibly fun and rewarding, but there are plenty of opportunities to run head first into walls you may not have realized even existed.<p>Aside from the ethics considerations, privacy regulations (and the desire to tread conservatively) can lead to some odd implementation decisions...especially if you&#x27;re coming into the industry from a general or consumer oriented tech background.<p>I once worked on a medication adherence project for patients in Italy where patients needed to complete bi-weekly assessments and generally track their medication adherence. We set up a secure portal&#x2F;website for patients, but were prohibited from emailing them reminders when their next assessment was due.<p>The sponsor (aka pharma co) was extremely conservative re: patient privacy laws and more or less left it at, &quot;well, the patient will just have to remember to return to the website, log in, and complete their survey at the appointed time.&quot; After a couple of months of sub-optimal survey completion rates, they re-evaluated their position and let us send out survey reminder emails.....which is a baseline thing to do when you need to retain participants over the life of a study.<p>Oddly enough, this was for a commercial project (medication was available on the market, physicians were referring their patients to this website as a value added sort of service) and the commercial side is a bit more wild west than phase 2&#x2F;3 research. Well, as wild west as the pharma&#x2F;clinical research industry gets :)<p>There are parallels between customer acquisition&#x2F;retention in SaaS and patient recruitment&#x2F;retention in clinical trials that are pretty interesting...but I think most folks on the Saas side would think the healthcare folks are trying to solve problems with one (if not two) hands tied behind their backs - and in some cases, wouldn&#x27;t be wrong in thinking so.
