Objective: To generate evidence of the effectiveness of hip protectors to minimize risk of hip fracture at the time of falling among residents of long-term care (LTC) by contrasting rates of hip fractures between falls with and without hip protectors.
Design: A 12-month, retrospective cohort study. We retrospectively reviewed fall incident reports recorded during the 12 months prior to baseline in participating homes.
Setting And Participants: A population-based sample comprising all residents from 14 LTC homes owned and operated by a single regional health authority, who experienced at least 1 recorded fall during the 12-month study.
Results: At baseline, the pooled mean (standard deviation) age of residents in participating homes was 82.7 (11.3) years and 68% were female. Hip protectors were worn in 2108 of 3520 (60%) recorded falls. Propensity to wear hip protectors was associated with male sex, cognitive impairment, wandering behavior, cardiac dysrhythmia, use of a cane or walker, use of anti-anxiety medication, and presence of urinary and bowel incontinence. The incidence of hip fracture was 0.33 per 100 falls in falls with hip protectors compared with 0.92 per 100 falls in falls without hip protectors, representing an unadjusted relative risk (RR) of hip fracture of 0.36 (95% confidence interval 0.14-0.90, P = .029) between protected and unprotected falls. After adjusting for propensity to wear hip protectors, the RR of hip fracture was 0.38 (95% confidence interval 0.14-0.99, P = .048) during protected vs unprotected falls.
Conclusions And Implications: Hip protectors were worn in 60% of falls, and the risk of hip fracture was reduced by nearly 3-fold by wearing a hip protector at the time of falling. Given that most clinical trials have failed to attain a similar level of adherence, our findings support the need for future research on the benefits of dissemination and implementation strategies to maximize adherence with hip protectors in LTC.

Introduction: The use of theories, models and/or frameworks (TMFs) in implementation research and practice is essential for developing useful and testable implementation strategies. Recommendations and tools exist to aid implementation groups in selecting TMFs, but they do not explicitly outline a systematic method for identifying and selecting TMFs. This paper aimed to (1) propose a systematic consensus-based method to select TMFs to support implementation processes, and to (2) demonstrate the use of this novel method in the context of researching the implementation of hip protectors for fracture prevention in long-term care (LTC).

Mainstream approaches to nutrition typically focus on diet consumption, overlooking multi-dimensional aspects of nutrition that are important to American Indian/Alaska Native (AI/AN) communities. To address health challenges faced by AI/AN communities, strengths-based measures of nutrition grounded in community worldviews are needed. In collaboration with AI/AN communities in Baltimore and Minneapolis, we developed the Indigenous Nourishment Scales through three phases.

Falls and hip fractures are a major health concern among older adults in long term care (LTC) with almost 50% of residents experiencing a fall annually. Hip fractures are one of the most important and frequent fall-related injuries in LTC. There is moderate to strong certainty evidence that multifactorial interventions may reduce the risk of falls and fractures; however, there is little evidence to support its implementation.

Osteosarcopenia is an emerging clinical condition highly prevalent in the older people. Affected subjects due to their intrinsic skeletal fragility and propensity to falls are at elevated risk of hip fractures which can increase morbidity and mortality. Strategies for attenuating the impact of predisposing factors on hip fractures are not yet well defined and should derive from multidisciplinary care and collaborations.

Osteoporosis is characterized by loss of bone mineral density and increased fracture risk. Reduction of hip fracture incidence is of major clinical importance. Hip protectors aim to attenuate the impact force transmitted to the femur upon falling, however different conclusions on their efficacy have been reported; some authors suggest this may be due to differences in compliance.
