Mobile health (mHealth) and wearable technology may provide health information to empower patients when communicating with providers and in turn shorten the time to diagnosis. We conducted three online co-design focus groups with POTS patients to determine elements of a desirable mHealth intervention. Themes emerged that helped us develop a smartphone- and wearable-based system, using a risk communication model as a message design framework. A pilot randomized trial is ongoing to test the POTS App. Initial results showed the app reaches high usability.<\/jats:p>","DOI":"10.3233\/shti251192","type":"book-chapter","created":{"date-parts":[[2025,8,7]],"date-time":"2025-08-07T11:44:02Z","timestamp":1754567042000},"source":"Crossref","is-referenced-by-count":0,"title":["A Co-Designed and Theory-Based Mobile Health App for Patients with Postural Orthostatic Tachycardia Syndrome (POTS): Development and Usability Testing"],"prefix":"10.3233","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6209-2420","authenticated-orcid":false,"given":"Jami","family":"Warren","sequence":"first","affiliation":[{"name":"University of Kentucky College of Health Sciences, Lexington, KY, USA"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7130-1415","authenticated-orcid":false,"given":"Ming-Yuan","family":"Chih","sequence":"additional","affiliation":[{"name":"University of Kentucky College of Health Sciences, Lexington, KY, USA"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4668-4359","authenticated-orcid":false,"given":"Deanna D.","family":"Sellnow","sequence":"additional","affiliation":[{"name":"Clemson University Department of Communication, Clemson, SC, USA"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6748-0617","authenticated-orcid":false,"given":"John","family":"Kotter","sequence":"additional","affiliation":[{"name":"University of Kentucky College of Medicine, Lexington, KY, USA"}]}],"member":"7437","container-title":["Studies in Health Technology and Informatics","MEDINFO 2025 \u2014 Healthcare Smart \u00d7 Medicine Deep"],"original-title":[],"link":[{"URL":"https:\/\/ebooks.iospress.nl\/pdf\/doi\/10.3233\/SHTI251192","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,7]],"date-time":"2025-08-07T11:44:03Z","timestamp":1754567043000},"score":1,"resource":{"primary":{"URL":"https:\/\/ebooks.iospress.nl\/doi\/10.3233\/SHTI251192"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,8,7]]},"ISBN":["9781643686080"],"references-count":0,"URL":"https:\/\/doi.org\/10.3233\/shti251192","relation":{},"ISSN":["0926-9630","1879-8365"],"issn-type":[{"value":"0926-9630","type":"print"},{"value":"1879-8365","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,8,7]]}}}
