Point prevalence of suboptimal footwear features among ambulant older hospital patients: implications for fall prevention

Foot Problems in Older Adults Presenting to a Falls and Balance Clinic

INTRODUCTION

Foot problems, including musculoskeletal problems, peripheral neuropathy, peripheral arterial disease and dermatologic pathology are common in older adults and are associated with an increased risk of falling. Multicomponent podiatry interventions have been shown to reduce the incidence of falls. This paper aimed to identify older adults requiring podiatry input in a Falls and Balance clinic; to describe the model of foot health care they receive; to explore cross-sectional associations between foot problems and function and ultimately demonstrate the role of podiatry input in the multidisciplinary management of falls risk.

METHODS

Cohort study of patients attending a Falls and Balance Clinic for Comprehensive Geriatric Assessment. Demographic information was collected and functional independence, mobility, foot problems, and footwear were assessed in the clinic.

RESULTS

One-hundred and two patients were included; median age 79.3 (73-84.3) years, 68.6% female, 93.1% residing independently, 62.7% used a gait aid. Podiatry referrals were made in 80.4% of cases, with muscle weakness being the most common problem identified (90.2%); 74.8% were found to be wearing inappropriate footwear. Most patients received footwear education and half were prescribed foot and ankle strengthening exercises. Hallux and lesser toe weakness were associated with lower Short Physical Performance Battery scores (p < 0.001).

CONCLUSION

The majority of older adults in the Falls and Balance Clinic required podiatry input, with foot weakness and inappropriate footwear being common reasons for referral. Those with weakness of the hallux and lesser toes had poorer balance and mobility, which is known to be associated with greater falls risk. This highlights the need for podiatry assessment and interventions as part of the multidisciplinary approach to the management of falls risk in older adults.

Footwear and Falls in Long-Term Residential Aged Care Facilities: An Analysis of Video Capture Data

INTRODUCTION

Several footwear characteristics have been shown to affect balance and gait patterns and may therefore influence the risk of falling in older adults. However, attributing a link between footwear and falls is inherently difficult as it often relies on self-report which may be inaccurate.

METHODS

Archival video recordings of falls that occurred in two long-term residential aged care facilities were initially screened to determine whether the footwear worn at the time (barefoot, socks, slippers/sandals, or shoes) could be documented. These falls were then independently evaluated by three additional assessors and a meeting was held to obtain consensus in relation to whether the footwear could have potentially contributed to the fall, and what mechanism may have been responsible. Cross-tabulations were performed in relation to footwear type and fall characteristics (proposed mechanism and fall direction).

RESULTS

There were 300 falls experienced by 118 older adults aged 58 years-98 years (mean age 82.8 years, SD 7.6). Of these falls, footwear could be ascertained in 224 (75%). After the consensus meeting, the proportion of falls considered to be potentially related to footwear was 40 (18%). The likelihood of footwear contributing to the fall was highest when participants were wearing socks (14/19 falls; 74% of all footwear-related falls), followed by being barefoot (2/6 falls; 33%), wearing slippers/sandals (17/100 falls; 17%), and wearing shoes (7/99 falls, 7%).

CONCLUSION

Footwear could be a potential contributor to a substantial number of falls in residential aged care. Wearing socks would appear to place an older person at risk of future falls and should therefore be avoided in this population.
