However, there are concerns about its feasibility and validity compared to traditional clinic spirometry. The aim of this study was to evaluate the feasibility and validity of telehealth spirometry for patients with CF living in a regional setting. Methods: This retrospective study included forty-eight people with cystic fibrosis (pwCF) aged 6\u201333 years. Participants performed home spirometry using a portable flow sensor spirometer over a one-year period, without supervision. Spirometry readings from portable spirometers were compared with the nearest in-clinic spirometry using the intra-correlation coefficient (ICC) and Bland\u2013Altman plots. Data were collected over a period of one year, with regular intervals of measurements. Results: In 427 of the 877 (48.6%) attempted sessions, successful spirometry at home was recorded. Although we showed good reliability between at-home and in-clinic measurements using the Bland\u2013Altman plots and intraclass correlation co-efficient (ICC) (values ranged from 0.76 to 0.88), analysis of the 117 pairs of at-home and in-clinic spirometries showed that mean differences of forced expiratory volume in the 1st sec (FEV1) and forced vital capacity (FVC) obtained at home (both in liter and z-score) had, on average, lower values than the corresponding values at the clinic. Conclusions: Home-based telehealth spirometry is feasible among pwCF and provides advantages, especially for those from remote or secluded areas. However, lower values in FVC and FEV1 obtained through home spirometry should not be used interchangeably with clinic values.<\/jats:p>","DOI":"10.3390\/children12030277","type":"journal-article","created":{"date-parts":[[2025,2,25]],"date-time":"2025-02-25T03:40:12Z","timestamp":1740454812000},"page":"277","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["The Feasibility and Validity of Home Spirometry for People with Cystic Fibrosis: Is It Comparable to Spirometry in the Clinic?"],"prefix":"10.3390","volume":"12","author":[{"given":"Athina","family":"Sopiadou","sequence":"first","affiliation":[{"name":"Pediatric Pulmonology and CF Unit, Hippokration Hospital of Thessaloniki, Aristotle University of Thessaloniki, 54124 Thessaloniki, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maria","family":"Gioulvanidou","sequence":"additional","affiliation":[{"name":"Pediatric Pulmonology and CF Unit, Hippokration Hospital of Thessaloniki, Aristotle University of Thessaloniki, 54124 Thessaloniki, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0864-9985","authenticated-orcid":false,"given":"Christos","family":"Kogias","sequence":"additional","affiliation":[{"name":"Pediatric Pulmonology and CF Unit, Hippokration Hospital of Thessaloniki, Aristotle University of Thessaloniki, 54124 Thessaloniki, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elissavet-Anna","family":"Chrysochoou","sequence":"additional","affiliation":[{"name":"Pediatric Pulmonology and CF Unit, Hippokration Hospital of Thessaloniki, Aristotle University of Thessaloniki, 54124 Thessaloniki, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-7614-038X","authenticated-orcid":false,"given":"Ioustini","family":"Kalaitzopoulou","sequence":"additional","affiliation":[{"name":"Pediatric Pulmonology and CF Unit, Hippokration Hospital of Thessaloniki, Aristotle University of Thessaloniki, 54124 Thessaloniki, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9505-2054","authenticated-orcid":false,"given":"Elpis","family":"Hatziagorou","sequence":"additional","affiliation":[{"name":"Pediatric Pulmonology and CF Unit, Hippokration Hospital of Thessaloniki, Aristotle University of Thessaloniki, 54124 Thessaloniki, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,2,25]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2195","DOI":"10.1016\/S0140-6736(20)32542-3","article-title":"Cystic fibrosis","volume":"397","author":"Shteinberg","year":"2021","journal-title":"Lancet"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"153","DOI":"10.1016\/j.jcf.2018.02.006","article-title":"ECFS best practice guidelines: The 2018 revision","volume":"17","author":"Castellani","year":"2018","journal-title":"J.
