Overview

Background People with mild cognitive impairment (MCI) fall as often as people living with early dementia. Yet, few trials have investigated the effectiveness of fall prevention interventions for people with MCI. Recruitment of specific populations into long-term trials can be challenging, and to assist future studies, it is necessary to better understand more about trial recruitment. This study outlines the recruitment of people with MCI into the Balance on the Brain trial. This was a single-blind randomised controlled trial based in the Perth Metropolitan Area, which included people living with MCI in the community, aged 50 or over, and who were self-reported to not be meeting the Australian physical activity guidelines. The multi-modal exercise intervention was for 6 months, and all participants were followed up monthly for 12 months. A sample size of 396 was calculated to meet the requirements for the falls primary outcome (212 participants for the balance primary outcome). Methods Eleven recruitment strategies were used across the 36-month recruitment (January 2021 through to December 2023). Some recruitment strategies had costs, and these are also outlined. Results A total of 780 potential participants were initially prescreened, 258 completed full REDCap ® screening, and 128 people were recruited. Memory clinics/hospitals were the most successful recruitment source, followed by Facebook advertisements and radio. Discussion Recruiting people with MCI can be difficult, exacerbated in this study by the concurrent COVID-19 pandemic. Less restrictive inclusion criteria and multisite recruitment may provide greater success. Trials registration Australian New Zealand Clinical Trials Registry (ANZCTRN) ACTRN12620001037998.
