The score also included health status, dyspnoea and forced expiratory volume in 1\u2005s (HADO.2 score).<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A prospective, observational, non-intervention study was carried out. Patients were recruited from the six outpatient clinics of the respiratory service of a single university hospital. The component variables of the HADO.2 score and BODE index were studied, and PA was measured using an accelerometer. The outcomes for the HADO.2 score were mortality and hospitalisations during follow-up and an exploration of the correlation with health-related quality of life at the moment of inclusion in the study.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>401 patients were included in the study and followed up for three years. The HADO.2 score showed good predictive capacity for mortality: C-index 0.79 (0.72\u20130.85). The C-index for hospitalisations was 0.72 (0.66\u20130.77) and the predictive ability for quality of life, as measured by R2, was 0.63 and 0.53 respectively for the Saint George's Respiratory Questionnaire and COPD Assessment Test.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>There was no statistically significant difference between the mortality predictive capacity of the HADO.2 score and the BODE index. Adding PA to the original BODE index significantly improved the predictive capacity of the index. The HADO.2 score, which includes PA as a key variable, showed good predictive capacity for mortality and hospitalisations. There were no differences in the predictive capacity of the HADO.2 score and the BODE index.<\/jats:p><\/jats:sec>","DOI":"10.1183\/23120541.00488-2023","type":"journal-article","created":{"date-parts":[[2024,1,11]],"date-time":"2024-01-11T17:05:25Z","timestamp":1704992725000},"page":"00488-2023","update-policy":"https:\/\/doi.org\/10.1183\/ers-crossmark-policy","source":"Crossref","is-referenced-by-count":4,"title":["Influence of physical activity on the prognosis of COPD patients: the HADO.2 score \u2013 health, activity, dyspnoea and obstruction"],"prefix":"10.1183","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1199-9166","authenticated-orcid":false,"given":"Crist\u00f3bal","family":"Esteban","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nere","family":"Larrea","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Amaia","family":"Aramburu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Javier","family":"Moraza","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Leyre","family":"Chasco","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Myriam","family":"Aburto","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Susana","family":"Aizpiri","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3759-5322","authenticated-orcid":false,"given":"Rafael","family":"Golpe","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2170-7876","authenticated-orcid":false,"given":"Jos\u00e9 M.","family":"Quintana","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"81","published-online":{"date-parts":[[2024,1,11]]},"reference":[{"key":"2024121407200841000_10.1.00488-2023.1","unstructured":"Global Initiative for Chronic Obstructive Lung Disease (GOLD) . 2023 Global Strategy for the Diagnosis, Management and Prevention of COPD. https:\/\/goldcopd.org\/2023-gold-report-2\/"},{"key":"2024121407200841000_10.1.00488-2023.2","doi-asserted-by":"crossref","first-page":"754004","DOI":"10.3389\/fimmu.2021.754004","article-title":"The role of extracellular vesicles as a shared disease mechanism contributing to multimorbidity in patients with COPD","volume":"12","author":"Reid","year":"2021","journal-title":"Front Immunol"},{"key":"2024121407200841000_10.1.00488-2023.3","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMoa021322"},{"key":"2024121407200841000_10.1.00488-2023.4","doi-asserted-by":"publisher","DOI":"10.1016\/j.rmed.2008.12.005"},{"key":"2024121407200841000_10.1.00488-2023.5","doi-asserted-by":"crossref","first-page":"276","DOI":"10.1016\/j.pulmoe.2020.10.008","article-title":"Development and validation of a prognostic index (BODEXS90) for mortality in stable chronic obstructive pulmonary disease","volume":"29","author":"Golpe","year":"2023","journal-title":"Pulmonology"},{"key":"2024121407200841000_10.1.00488-2023.6","doi-asserted-by":"publisher","DOI":"10.1183\/09031936.00138507"},{"key":"2024121407200841000_10.1.00488-2023.7","doi-asserted-by":"publisher","DOI":"10.1136\/thx.2006.060145"},{"key":"2024121407200841000_10.1.00488-2023.8","doi-asserted-by":"publisher","DOI":"10.1183\/09031936.00024608"},{"key":"2024121407200841000_10.1.00488-2023.9","doi-asserted-by":"publisher","DOI":"10.1378\/chest.11-2014"},{"key":"2024121407200841000_10.1.00488-2023.10","doi-asserted-by":"publisher","DOI":"10.1378\/chest.10-2521"},{"key":"2024121407200841000_10.1.00488-2023.11","doi-asserted-by":"publisher","DOI":"10.1186\/1741-7015-8-28"},{"key":"2024121407200841000_10.1.00488-2023.12","doi-asserted-by":"publisher","DOI":"10.1093\/qjmed\/hcl110"},{"key":"2024121407200841000_10.1.00488-2023.13","doi-asserted-by":"publisher","DOI":"10.1136\/thx.54.7.581"},{"key":"2024121407200841000_10.1.00488-2023.14","doi-asserted-by":"publisher","DOI":"10.1016\/0021-9681(87)90171-8"},{"key":"2024121407200841000_10.1.00488-2023.15","doi-asserted-by":"publisher","DOI":"10.1183\/09031936.96.09061160"},{"key":"2024121407200841000_10.1.00488-2023.16","doi-asserted-by":"publisher","DOI":"10.3109\/15412555.2012.692409"},{"key":"2024121407200841000_10.1.00488-2023.17","doi-asserted-by":"crossref","first-page":"388","DOI":"10.1016\/j.arbres.2013.04.001","article-title":"Spirometry.
