BACKGROUND: Ultrasound guided regional anesthesia is widely taught using task trainer models. Commercially available models are often used; however, they can be cost prohibitive. Therefore, alternative "homemade" models with similar fidelity are often used. We hypothesize that professional task trainers will be preferred over homemade models. The purpose of this study is to determine realism, durability and cleanliness of three different task trainers for ultrasound guided nerve blocks. METHODS: This was a prospective observational study using a convenience sample of medical student participants in an ultrasound guided nerve block training session on January 24th, 2015. Participants were asked to perform simulated nerve blocks on three different task trainers including, 1 commercial and 2 homemade. A questionnaire was then given to all participants to rate their experiences both with and without the knowledge on the cost of the simulator device. RESULTS: Data was collected from 25 participants. The Blue Phantom model was found to have the highest fidelity. Initially, 10 (40%) of the participants preferred the Blue Phantom model, while 10 (40%) preferred the homemade gelatin model and 5 (20%) preferred the homemade tofu model. After cost awareness, the majority, 18 (72%) preferred the gelatin model. CONCLUSION: The Blue Phantom model was thought to have the highest fidelity, but after cost consideration the homemade gelatin model was preferred.

With the Singaporean population ageing at an exponential rate, home carers are increasingly becoming essential partners in fall prevention and care delivery for older persons living at home and in the community. Singapore, like other Asian countries, regards the family as the main support structure for the older person, and national policies have been implemented to support this cultural expectation. Family carers experience similar concerns as older persons with regard to fall risk, and identifying and addressing these concerns can potentially lower fall risk and improve fall prevention for older persons. It is timely to remind ourselves - as concern about falls in older persons begins to shift to carers - to incorporate the influence of Asian cultural values and unique family dynamics of outsourcing family caregiving, in the management of older persons' fall risk in the community.

Falls, the leading cause of injury and death among older people, can have a significant psychosocial impact on carers. Carers play a crucial role in caring for older persons at home and in fall prevention. This review, which included 15 studies, aimed to identify carers' concern about older people falling and its impact. We identified that most carers had concerns about repeated falls in older people, unknown consequences of falls and care recipients' non-adherence to fall prevention advice. These concerns, in turn, affect carers' physical and psychological health, lifestyle, caregiving burden and use of fall prevention strategies. This paper highlights the importance of recognising carers' fall concern so as to identify carers' needs and awareness of fall prevention in older people living at home. Greater insight into carers' fall concern could facilitate the implementation of new strategies to manage older people's fall risk as well as improve carers' well-being.
