Moreover, once diagnosed and discharged from the hospital, the 30-day readmission risk in COPD patients is found to be the highest among all chronic diseases. The existing diagnosis methods, such as Global Initiative for Chronic Obstructive Lung Disease (GOLD) 2019, Body-mass index, airflow Obstruction, Dyspnea, and Exercise (BODE) index, modified Medical Research Council (mMRC), COPD assessment test (CAT), 6-minute walking distance, which are adopted currently by physicians cannot predict the potential readmission of COPD patients, especially within the 30 days after discharge from the hospital. In this paper, a statistical model was proposed to predict the readmission risk of COPD patients within 30-days by monitoring their physical activity (PA) in daily living with accelerometer-based wrist-worn wearable devices. This proposed model was based on our previously reported PA models for activity index (AI) and regularity index (RI) and it introduced a new parameter, quality of activity (QoA), which incorporates previously proposed parameters, such as AI and RI, with other activity-based indices to predict the readmission risk. Data were collected from continuous PA monitoring of 16 COPD patients after hospital discharge as test subjects and readmission prediction criteria were proposed, with a 63% sensitivity and a 37.78% positive prediction rate. Compared to other clinical assessment, diagnosis, and prevention methods, the proposed model showed significant improvement in predicting the 30-day readmission risk.<\/jats:p>","DOI":"10.3390\/s20010217","type":"journal-article","created":{"date-parts":[[2020,1,3]],"date-time":"2020-01-03T03:28:53Z","timestamp":1578022133000},"page":"217","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Prediction of 30-Day Readmission for COPD Patients Using Accelerometer-Based Activity Monitoring"],"prefix":"10.3390","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5748-0151","authenticated-orcid":false,"given":"Wen-Yen","family":"Lin","sequence":"first","affiliation":[{"name":"Department of Electrical Engineering, Center for Biomedical Engineering, Chang Gung University, Tao-Yuan 33302, Taiwan"},{"name":"Division of Cardiology, Department of Internal Medicine, Chang Gung Memorial Hospital, Tao-Yuan 33305, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2032-7321","authenticated-orcid":false,"given":"Vijay Kumar","family":"Verma","sequence":"additional","affiliation":[{"name":"Department of Electrical Engineering, Center for Biomedical Engineering, Chang Gung University, Tao-Yuan 33302, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2031-0183","authenticated-orcid":false,"given":"Ming-Yih","family":"Lee","sequence":"additional","affiliation":[{"name":"Division of Cardiology, Department of Internal Medicine, Chang Gung Memorial Hospital, Tao-Yuan 33305, Taiwan"},{"name":"Graduate Institute of Biomedical Engineering, Center for Biomedical Engineering, Chang Gung University, Tao-Yuan 33302, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Horng-Chyuan","family":"Lin","sequence":"additional","affiliation":[{"name":"Department of Thoracic Medicine, Chang Gung Memorial Hospital, Tao-Yuan 33305, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chao-Sung","family":"Lai","sequence":"additional","affiliation":[{"name":"Department of Electronic Engineering, Center for Biomedical Engineering, Chang Gung University, Tao-Yuan 33302, Taiwan"},{"name":"Department of Nephrology, Chang Gung Memorial Hospital, Linkou, Tao-Yuan 33305, Taiwan"},{"name":"Department of Materials Engineering, Ming Chi University of Technology, New Taipei 24301, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2019,12,30]]},"reference":[{"key":"ref_1","unstructured":"(2019, November 23).
