Risk factors associated with visiting or not visiting the accident & emergency department after a fall.

BACKGROUND: Little is known about the prevalence of modifiable risk factors of falling in elderly persons with a fall-history who do not visit the Accident and Emergency (A&E) Department after one or more falls. The objective of this study was to determine the prevalence of modifiable risk factors in a population that visited the A&E Department after a fall (A&E group) and in a community-dwelling population of elderly individuals with a fall history who did not visit the A&E Department after a fall (non-A&E group). METHODS: Two cohorts were included in this study. The first cohort included 547 individuals 65 years and older who were visited at home by a mobile fall prevention team. The participants in this cohort had fall histories but did not visit the A&E Department after a previous fall. These participants were age- and gender-matched to persons who visited the A&E Department for care after a fall. All participants were asked to complete the CAREFALL Triage Instrument. RESULTS: The mean number of modifiable risk factors in patients who did not visit the A&E Department was 2.9, compared to 3.8 in the group that visited the A&E Department (p<0.01). All risk factors were present in both groups but were more prevalent in the A&E group, except for the risk factors of balance and mobility (equally prevalent in both groups) and orthostatic hypotension (less prevalent in the A&E group). The risk factors of polypharmacy, absence of orthostatic hypotension, fear of falling, impaired vision, mood and high risk of osteoporosis were all independently associated with visiting the A&E Department. CONCLUSION: All modifiable risk factors for falling were found to be shared between community-dwelling elderly individuals with a fall history who visited the A&E Department and those who did not visit the Department, although the prevalence of these factors was somewhat lower in the A&E group. Preventive strategies aimed both at patients presenting to the A&E Department after a fall and those not presenting after a fall could perhaps reduce the number of recurrent falls, the occurrence of injury and the frequency of visits to the A&E Department.

Assessing the prevalence of modifiable risk factors in older patients visiting an ED due to a fall using the CAREFALL Triage Instrument.

OBJECTIVE: Falls in older people are a common presenting complaint. Knowledge of modifiable risk factors may lead to a more tailored approach to prevent recurrent falls and/or fractures. We investigated prevalence of 8 modifiable risk factors for recurrent falling and/or a serious consequence of the fall among older patients visiting the emergency department after a fall with the Combined Amsterdam and Rotterdam Evaluation of Falls Triage Instrument (CTI), a self-administrated questionnaire that consists of questions concerning demographics, possible cause(s) of the fall, and questions relating to (modifiable) risk factors for falling. METHODS: After treatment for their injuries, 1077 consecutive patients 65 years or older visiting the accident and emergency department due to a fall were evaluated by the CTI. The following were assessed: impaired vision, mobility disorder, fear of falling, mood disorder, high risk of osteoporosis, orthostatic hypotension, incontinence, and polypharmacy. RESULTS: The percentage of respondents who returned the questionnaire was 59.3%. The mean (SD) age was 78.5 (7.5) years, and 57.8% experienced a fall with serious consequences. There were 60.9% of patients with a recurrent fall versus 51% with a first fall who experienced with a serious consequence (P = .025). Age and risk factors mobility disorder (odds ratio [OR], 1.9; 95% confidence interval [CI], 1.1-3.3), high risk of osteoporosis (OR, 2.0; 95% CI, 1.2-3.2), incontinence (OR, 1.7; 95% CI, 1.0-2.7), fear of falling (OR, 2.2; 95% CI, 1.3-3.7), and orthostatic hypotension (OR, 2.4; 95% CI, 1.4-4.2) were independently associated with a recurrent fall. Age and high risk of osteoporosis were the only risk factors predicting a serious consequence of a fall (OR, 4.6; 95% CI, 2.9-7.2). CONCLUSIONS: Age and 5 modifiable risk factors assessed with the CTI were independently associated with a recurrent fall. Only high risk of osteoporosis was associated with a serious consequence.
