This study examined the six-month prevalence, risk factors, and costs of falls in older people using home support services who are at risk of falling. Of the 109 participants, 70.6 per cent reported >or= one fall in the previous six months, and 27.5 per cent experienced multiple falls. Although there was no statistically significant difference in any fall-related risk factor between fallers (1+ falls) and non-fallers (0 falls), fallers had clinically important trends towards lower levels of physical, social, and psychological functioning. There was no statistically significant difference between fallers and non-fallers in the total per-person costs of use of health services in the previous six months; however, there were significant differences between groups in specific types of health services. The multivariate analysis revealed the presence of five risk factors for falls: neurological disorder (e.g., cognitive impairment, Parkinson's disease), age >or= 85 years, environmental hazards, previous slip or trip, and visual impairment.
