Falls are common causes of disability, reduced disability-adjusted life years and death in older adults. Balance deficits and cognitive impairment are common causes of falls. Dual-task training is a new strategy that can potentially improve balance and cognitive function, leading to decreased falls. The effectiveness and cost-effectiveness of self-administered dual-task (sDT) training to improve balance and prevent falls is not known. We developed sDT training combining physical and cognitive tasks to improve balance and reduce falls. The proposed randomised controlled trial (RCT) with economic evaluation is to test the effectiveness and cost-effectiveness of the sDT compared with self-administered single-task training (sST) in this population.

In this RCT, we will recruit 190 community-dwelling older adults with a history of at least one fall over the last 6 months from 11 elderly centres. The older adults will be randomly assigned to the sDT (n=95) and sST groups (n=95). Each group will be offered in six training workshops to teach the participants either sDT or sST depending on the group allocation. Each workshop will last an hour and will be held once every 2 weeks for 3 months. Besides, the participants will be instructed to repeat the exercises at home two times weekly for 3 months. Following the intervention phase, the participants will continue unsupervised home-based exercises for 6 months. Assessments will be performed before, after and 6 months after completing the intervention. A fall calendar and cost diary will be provided to each older adult to record the number of falls and fall-related costs during and after the intervention to assess fall incidence and cost-effectiveness. Effectiveness will be assessed using a negative binomial regression model following the intention-to-treat principle for falls and a linear mixed model for the additional measure and cost-effectiveness using a Markov model.

This study has ethical approval from the PolyU Institutional Review Board for conducting research on human subjects (Ref: HSEARS20210322005). The results will be disseminated through seminars for individuals and health practitioners, international conferences and published in peer-reviewed journals.

The New York City (NYC) HIV Care Coordination Programme (CCP) is designed to help people with HIV (PWH) overcome barriers to care and treatment engagement. We assessed preferences for CCP components among programme enrollees (’clients’) and providers. Our objective is to compare client and provider preferences, which were previously analysed separately.

We used a discrete choice experiment to assess preferences for four CCP features (‘attributes’): Help with Adherence to Antiretroviral Therapy (ART), Help with Primary Care Appointments, Help with Issues other than Primary Care and Where Programme Visits Happen. Each of these attributes had 3–4 variants (‘levels’). In the original surveys, levels within Where Programme Visits Happen varied by participant type (client vs provider). We recoded the levels by visit location (VL) or by travel time (TT) to make them comparable and report results from both approaches.

25 Ryan White Part A-funded NYC CCPs participated.

152 providers and 181 clients completed the survey.

Preferences were quantified using the relative importance of the attributes and utility of the levels.

From January 2020 to March 2021, 152 providers and 181 clients completed the survey. Most of the providers (52%) were

Client and provider preferences clearly diverged regarding CCP service intensity: in the aggregate, clients tended to prefer lower-intensity services, whereas providers endorsed higher-intensity services. These results highlight the importance of engaging clients as partners in decisions about programme services to facilitate alignment with client values.
