Patients presenting to family physicians after a fall: a report from the Ambulatory Sentinel Practice Network

Patients who fall present a diagnostic challenge to family physicians. The diagnostic workup of these patients must be thorough enough to detect and treat important causes of the fall yet not subject patients to unnecessary tests. Previous studies have provided only limited guidance for primary care physicians because in general they occurred in settings other than primary care and focused on a single age group.

The Ambulatory Sentinel Practice Network (ASPN) conducted a 6-month study of primary care patients of all ages presenting after a fall, or with medical problems resulting from a fall. ASPN clinicians collected information about the history, physical examination findings, and follow-up of these patients. Causes of falls were grouped into three categories: external reasons for falling, internal reasons related to gait, and internal reasons unrelated to gait.

Participating clinicians identified 431 patients who had falls out of the 256,680 seen for any reason during the study period. The patients ranged in age from 1 to 94 years. The rate of falls for patients increased rapidly after age 65 years. Most falls occurred for reasons external to the patient, but internal reasons, both nonlocomotor and locomotor, increased after age 65 years. No nonlocomotor causes for a fall were found in patients younger than 65 years of age. Also, the rate of hospitalization of patients seen for falls was greater in the geriatric age group.

The results highlight the need for further research about falls, particularly those occurring in pediatric and young adult patients. Furthermore, correcting environmental hazards and modifying gait problems in the elderly by increasing lower extremity and truncal strength could decrease the risk of falling.
