Inferior vena cava (IVC) ultrasound provides a rapid, noninvasive estimation of intravascular volume. Teleguided point-of-care ultrasound (POCUS) allows examiners without prior ultrasound experience to perform scans under real-time supervision.<\/jats:p>\n <\/jats:sec>\n \n Objective<\/jats:title>\n This study aimed to evaluate the feasibility, accuracy, efficiency, and user satisfaction of remote-guided IVC ultrasound performed by medical students and nurses without prior ultrasound experience in a geriatric inpatient setting.<\/jats:p>\n <\/jats:sec>\n \n Methods<\/jats:title>\n This prospective feasibility study was conducted between February and March 2025 in a geriatric inpatient ward at a German tertiary care hospital. Thirty hospitalized geriatric patients were recruited using a pragmatic convenience sampling approach on predefined study days. Each patient underwent 2 IVC ultrasound examinations (n=60) using a handheld device with TeleGuidance; one was performed by a medical student and one by a nurse. All scans were remotely supervised by an ultrasound-experienced cardiologist, who subsequently performed a third, independent IVC scan on each patient, serving as the reference standard. Examiners were 2 final-year medical students and 2 nurses, all without ultrasound experience, each performing 15 scans. Primary outcomes were technical feasibility (successful teleguidance connection), accuracy of IVC diameter measurement (\u226580% within +2 mm to \u20132 mm), and examination duration (\u226410 minutes). The secondary outcome was user satisfaction (\u226575 on a 0-100 numeric rating scale).<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n Connectivity and remote supervision were consistently stable, enabling completion of all scans (feasibility 100%). IVC visualization was successful in 90% (27\/30) of cases. Accuracy was achieved in 80% (48\/60; 95% CI 67-88) of scans. Mean duration was 3.3 (SD 2.0) minutes. Mean user satisfaction was 89%, with all ratings \u226585%.<\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n Telemedicine-guided IVC ultrasound was feasible and well accepted in this geriatric inpatient setting. Nonexpert examiners were able to obtain clinically usable measurements under remote supervision within a few minutes after minimal training. These findings suggest that teleguided POCUS is a promising approach to support task sharing in geriatric care. Further studies are needed to confirm these results and to evaluate integration into clinical practice.<\/jats:p>\n <\/jats:sec>\n \n Trial Registration<\/jats:title>\n German Clinical Trials Register DRKS00035821; https:\/\/www.drks.de\/search\/de\/trial\/DRKS00035821\/details<\/jats:p>\n <\/jats:sec>","DOI":"10.2196\/88574","type":"journal-article","created":{"date-parts":[[2026,6,12]],"date-time":"2026-06-12T20:05:07Z","timestamp":1781294707000},"page":"e88574","source":"Crossref","is-referenced-by-count":0,"title":["Teleguided Point-of-Care Ultrasound for Fluid Assessment in Geriatric Inpatients Performed by Nurses and Medical Students: Prospective Observational Feasibility Study"],"prefix":"10.2196","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3937-5956","authenticated-orcid":false,"given":"Stephanie","family":"Heinemann","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-5839-7581","authenticated-orcid":false,"given":"Mira Fleur","family":"Seitz","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8614-2223","authenticated-orcid":false,"given":"Christine A F","family":"von Arnim","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5190-9551","authenticated-orcid":false,"given":"Carolin","family":"Steinmetz","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8622-0810","authenticated-orcid":false,"given":"Miroslava","family":"Valentov\u00e1","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1010","published-online":{"date-parts":[[2026,6,12]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.2196\/34952"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.3238\/arztebl.m2023.0182"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1016\/j.acvd.2025.01.007"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1016\/j.jamda.2025.105536"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1016\/j.rceng.2025.502393"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1002\/jcu.70004"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1002\/ajum.12335"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1055\/s-2005-836496"},{"issue":"9","key":"ref9","doi-asserted-by":"crossref","first-page":"896","DOI":"10.1093\/ptj\/80.9.896","volume":"80","author":"Shumway-Cook, A","year":"2000","journal-title":"Phys Ther"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1007\/s10278-018-0157-9"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.2196\/36824"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1186\/s12877-023-04313-2"}],"container-title":["JMIR Formative Research"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/formative.jmir.org\/2026\/1\/e88574","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,6,12]],"date-time":"2026-06-12T20:05:08Z","timestamp":1781294708000},"score":1,"resource":{"primary":{"URL":"https:\/\/formative.jmir.org\/2026\/1\/e88574"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,6,12]]},"references-count":12,"URL":"https:\/\/doi.org\/10.2196\/88574","relation":{"has-preprint":[{"id-type":"doi","id":"10.2196\/preprints.88574","asserted-by":"object"}]},"ISSN":["2561-326X"],"issn-type":[{"value":"2561-326X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,6,12]]}}}
