Senior adults aged 65 years and older represented only 2.5% of users and 1.2% of VCs. Monthly VC volumes in 2024 exceeded those in 2023, with some months recording nearly double the consultation numbers and surpassing 2500 VCs in the second half of 2024. Mean default (6.6%) and conversion (2.2%) rates showed a decreasing trend from 2023 to 2024. Referrals to emergency or specialist outpatient services constituted 5.6% of VCs. Acute medical conditions accounted for 82.7% of VCs, chronic disease management 12.4% and other reasons 4.9%, with upper respiratory tract infections comprising almost half of acute cases. Over half (50.9%) of consultations were not prescribed medications, of which 72.3% were issued sick leave. 81.3% of users had two or fewer sick leave issuances, including those with none.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Although AODTH outreach to older adults was low, the service was effective for acute medical management with low in-person consultation conversion despite the lack of physical examination. The rising trends of AODTH users and VCs over 2 years reflect gradual service adoption, while low defaulter and referral rates reflect an appropriate implementation framework. Prevalent medical certification is likely the cornerstone to maintain AODTH service as a means for recovery from acute illnesses.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1136\/fmch-2026-003988","type":"journal-article","created":{"date-parts":[[2026,8,12]],"date-time":"2026-08-12T12:40:27Z","timestamp":1786538427000},"page":"e003988","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Implementation outcomes from delivering \u2018acute-on-demand telehealth services\u2019 in primary care: a retrospective observational study"],"prefix":"10.1136","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5946-1149","authenticated-orcid":false,"given":"Ngiap Chuan","family":"Tan","sequence":"first","affiliation":[{"name":"Research, SingHealth Polyclinics, Singapore"},{"name":"SingHealth Duke NUS Family Medicine Academic Program, Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shen Yi Dominic","family":"Lim","sequence":"additional","affiliation":[{"name":"Duke-NUS Graduate Medical School, Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-2013-6138","authenticated-orcid":false,"given":"Win Yee","family":"Cheong","sequence":"additional","affiliation":[{"name":"SingHealth Polyclinics, Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yi Ling Eileen","family":"Koh","sequence":"additional","affiliation":[{"name":"SingHealth Polyclinics, Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chun-Yun Gary","family":"Kang","sequence":"additional","affiliation":[{"name":"SingHealth Duke NUS Family Medicine Academic Program, Singapore"},{"name":"SingHealth Polyclinics, Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-1796-6234","authenticated-orcid":false,"given":"Jambay","family":"Dorji","sequence":"additional","affiliation":[{"name":"SingHealth Duke NUS Family Medicine Academic Program, Singapore"},{"name":"SingHealth Polyclinics, Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2026,8,12]]},"reference":[{"key":"2026092308151843000_14.3.e003988.1","doi-asserted-by":"crossref","unstructured":"Stoltzfus M , Kaur A , Chawla A , et al .
