Abstract

Background: Patients with chronic obstructive pulmonary disease (COPD) often experience lung and extra-pulmonary impairments that lead to quadriceps muscle atrophy, limiting mobility and balance. The timed-up-and-go test is capable of evaluating fall risk and reflecting disease severity. Objective: To determine the fall risk prevalence in COPD patients using the timed-up-and-go test and fall risk screening questions. Methods: A study was conducted on 117 stable COPD patients at the Asthma - COPD Management Unit of Gia Dinh People's Hospital (6-8/2023). The time taken for the timed-up-and-go test was measured as patients transitioned from sitting to standing, walked 3 meters, turned around and walked back to the starting position, then turned around and sat down. Results: The mean age of patients was 67 ± 8 years. %FEV1 compared to the average predicted value was 56,6 ± 18,1%. The timed-up-and-go value for COPD patients was 11,2 seconds (9,8 – 12,9). The proportion of COPD patients with timed-up-and-go value exceeding 12,2 seconds was 29,9%. The fall incidence rate among COPD patients in the past year was 10,3%. The proportion of COPD patients with positive fall risk screening results was 34,2%. The optimal cutoff threshold for predicting falls based on timed-up-and-go value was 12,2 seconds, with sensitivity of 67%, specificity of 74%, AUROC of 0.71 (95% CI 0.55-0.87). Conclusion: Approximately one-third of the COPD patient population is at risk of falls. Timed-up-and-go test, along with fall risk screening questions, should be routinely implemented in stable COPD patients.
