Gait speed as a predictor of survival in geriatric patients

These US and European researchers sought to evaluate gait speed as a predictor for survival. They pooled 9 cohort studies (a total of 34 485 community-dwelling geriatric enrollees) with baseline gait speed data. They were followed up to to 21 years.

The researchers found: "There were 17,528 deaths. The overall 5-year survival rate was 84.8% and 10-year survival rate was 59.7%. Gait speed was associated with survival in all studies (pooled hazard ratio per 0.1 m/s, 0.88). Survival increased across the full range of gait speeds, with significant increments per 0.1 m/s. At age 75, predicted 10-year survival across the range of gait speeds ranged from 19% to 87% in men and from 35% to 91% in women. Predicted survival based on age, sex, and gait speed was as accurate as predicted based on age, sex, use of mobility aids, and self- reported function or as age, sex, chronic conditions, smoking history, blood pressure, body mass index, and hospitalization."

The researchers concluded: "In this pooled analysis of individual data from 9 selected cohorts, gait speed was associated with survival in older adults."

This study suggests gait speed may be useful in estimating survival in geriatric patients
