Predicting the Tumble: Recurrent Fall History and Dual-Task Impairment Emerge as Primary Risk Factors in COPD

Highlights

Chronic obstructive pulmonary disease (COPD) is increasingly recognized as a systemic condition where fall risk is significantly elevated, yet accurate prediction remains a challenge. A recent study has established a clinical prediction model with the following key findings:

• Approximately 42% of individuals with COPD experienced at least one fall over a 12-month prospective period.
• The final predictive model identified three robust factors: a history of two or more falls in the preceding year, a higher number of chronic conditions, and poor performance on the Timed Up and Go Dual-Task (TUG-DT) test.
• A history of recurrent falls (≥2) was the strongest predictor, increasing the odds of future falls by more than 3.5 times.
• The model demonstrated acceptable discrimination (c-statistic 0.69) and excellent calibration, providing a foundation for clinical screening.
