A single, simple question about a patient’s experience of falls in the previous year can help predict their risk of fractures, a study suggests.
In Osteoporosis International, researchers reported the outcomes of a cohort study using Manitoba clinical registry data from 24,943 men and women aged 40 years and older within the province who had undergone a fracture-probability assessment, and had data on self-reported falls for the previous year and fracture outcomes.
William D. Leslie, MD, of the University of Manitoba in Winnipeg, and coauthors wrote that a frequent criticism of the FRAX fracture risk assessment tool was the fact that it didn’t include falls or fall risk in predicting fractures.
“Recent evidence derived from carefully conducted research cohort studies in men found that falls increase fracture risk independent of FRAX probability,” they wrote. “However, data are inconsistent with a paucity of evidence demonstrating usefulness of self-reported fall data as collected in routine clinical practice.”
0.8% experienced a hip fracture, and 4.9% experienced any incident fracture.
The analysis showed an increased risk of fracture with the increasing number of self-reported falls experienced in the previous year. The risk of major osteoporotic fracture was 49% higher among individuals who reported one fall, 74% in those who reported two falls and 2.6-fold higher for those who reported three or more falls in the previous year, compared with those who did not report any falls.
A similar pattern was seen for any incident fracture and hip fracture, with a 3.4-fold higher risk of hip fracture seen in those who reported three or more falls. The study also showed an increase in mortality risk with increasing number of falls.
“We documented that a simple question regarding self-reported falls in the previous year could be easily collected during routine clinical practice and that this information was strongly predictive of short-term fracture risk independent of multiple clinical risk factors including fracture probability using the FRAX tool with BMD [bone mineral density],” the authors wrote.
The analysis did not find an interaction with age or sex and the number of falls.
