Many older people with wounds are treated in their homes, currently assessed by monitoring the wound area over weeks to ascertain the potential for healing. A noncontact method using thermal imaging has been shown to predict the healing trajectory of diabetes-related foot ulcers, although has not been tested in VLU or the home setting. This project investigated the effectiveness of using thermal imaging to predict VLU healing in the homes of participants. Images of 78 ulcers were collected weekly using a thermal camera from 67 participants in their homes, at 5 consecutive time points. Final follow-up calls were undertaken at 12 weeks to ascertain healing status (healed\/unhealed). Images were preprocessed and segmented and the area of the region of the wound was extracted. Kruskal\u2013Wallis tests were performed to test the association of the change of areas over the 5 consecutive weeks with the healing status of the ulcers at 12 weeks. The 95% confidence interval plots were obtained to study the distribution of the area in the healed and unhealed cases. This study found that the difference in the imaged areas between unhealed ulcers at 12 weeks did not reach statistical significance using thermal imaging. Therefore, thermal images could not predict healing progression in VLUs when the images were taken in the homes of participants. Future research to improve the prediction of venous leg ulcer healing should include developing a protocol to standardize conditions, improve imaging process methods, and use machine learning.<\/jats:p>","DOI":"10.1177\/15347346211002351","type":"journal-article","created":{"date-parts":[[2021,4,15]],"date-time":"2021-04-15T17:57:47Z","timestamp":1618509467000},"page":"85-92","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":7,"title":["Can Thermal Imaging Technique be Used to Predict the Healing Status of a Venous Leg Ulcer?"],"prefix":"10.1177","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4192-7254","authenticated-orcid":false,"given":"Rajna","family":"Ogrin","sequence":"first","affiliation":[{"name":"Bolton Clarke, Victoria, Australia"},{"name":"Royal Melbourne Institute of Technology University, Melbourne, Victoria, Australia"},{"name":"Griffith University, Brisbane, Queensland, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1618-3772","authenticated-orcid":false,"given":"Mohammod A.","family":"Motin","sequence":"additional","affiliation":[{"name":"Royal Melbourne Institute of Technology University, Melbourne, Victoria, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Behzad","family":"Aliahmad","sequence":"additional","affiliation":[{"name":"Royal Melbourne Institute of Technology University, Melbourne, Victoria, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kylie","family":"Elder","sequence":"additional","affiliation":[{"name":"Bolton Clarke, Victoria, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jacinta","family":"Anderson","sequence":"additional","affiliation":[{"name":"Bolton Clarke, Victoria, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dinesh","family":"Kumar","sequence":"additional","affiliation":[{"name":"Royal Melbourne Institute of Technology University, Melbourne, Victoria, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2021,4,15]]},"reference":[{"key":"bibr1-15347346211002351","doi-asserted-by":"publisher","DOI":"10.1016\/j.annepidem.2018.10.005"},{"issue":"2","key":"bibr2-15347346211002351","first-page":"14","volume":"3","author":"Briggs M","year":"2003","journal-title":"EWMA J"},{"key":"bibr3-15347346211002351","doi-asserted-by":"publisher","DOI":"10.1097\/00152192-200207000-00007"},{"key":"bibr4-15347346211002351","author":"de la Torre J","year":"2008","journal-title":"Medscape"},{"key":"bibr5-15347346211002351","first-page":"6","volume-title":"Skin breakdown, the silent epidemic","author":"Posnett J","year":"2007"},{"key":"bibr6-15347346211002351","volume-title":"Australia\u2019s health 2008","author":"AIHW","year":"2008"},{"key":"bibr7-15347346211002351","doi-asserted-by":"publisher","DOI":"10.1016\/S0190-9622(94)70134-2"},{"key":"bibr8-15347346211002351","doi-asserted-by":"publisher","DOI":"10.1016\/j.jccw.2013.11.001"},{"key":"bibr9-15347346211002351","doi-asserted-by":"publisher","DOI":"10.1111\/j.1742-481X.2012.01033.x"},{"key":"bibr10-15347346211002351","doi-asserted-by":"publisher","DOI":"10.1111\/iwj.12859"},{"key":"bibr11-15347346211002351","volume-title":"Australian and New Zealand clinical practice guideline for prevention and management of venous leg ulcers","author":"AWMA, NZWCS","year":"2011"},{"key":"bibr12-15347346211002351","doi-asserted-by":"publisher","DOI":"10.1111\/j.1524-475X.2007.00328.x"},{"key":"bibr13-15347346211002351","doi-asserted-by":"publisher","DOI":"10.2337\/dc06-2209"},{"key":"bibr14-15347346211002351","doi-asserted-by":"publisher","DOI":"10.1177\/193229681000400508"},{"key":"bibr15-15347346211002351","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(05)67696-9"},{"key":"bibr16-15347346211002351","doi-asserted-by":"publisher","DOI":"10.1016\/0046-8177(95)90037-3"},{"key":"bibr17-15347346211002351","doi-asserted-by":"publisher","DOI":"10.1177\/1932296818803115"},{"key":"bibr18-15347346211002351","unstructured":"KPMG.\n                      An economic evaluation of compression therapy for venous leg ulcers\n                      .
