Clinical Trial Summary

In the short term, the study will provide insight into the effectiveness of multi-component intervention for reducing Fear of falling (FoF) in community-dwelling older adults. Effective interventions will be incorporated into existing programs for frailty and falls prevention in primary care. Reducing FoF will break the cycle of physical activity restriction, functional decline and further falls in older adults. Long term potential benefits include improving the health status of older adults and thus reducing healthcare utilization. The primary aim is to compare the effectiveness of a multi-component intervention comprising exercise recommendations, cognitive behavioural therapy (CBT) components and motivational interviewing (MI) based telephone review against usual care for reducing Fear of Falling (FoF) in community- dwelling older adults. Secondary aims include to compare the effectiveness of the multi-component intervention against usual care for increasing physical activity and reducing falls in community- dwelling older adults. We hypothesize that the multi-component intervention will be more effective as compared to usual care for reducing FoF and falls and increasing physical activity in community- dwelling older adults.

Long term potential benefits include improving the health status of older adults and thus reducing healthcare utilization. The primary aim is to compare the effectiveness of a multi-component intervention comprising exercise recommendations, cognitive behavioural therapy (CBT) components and motivational interviewing (MI) based telephone review against usual care for reducing Fear of Falling (FoF) in community- dwelling older adults. Secondary aims include to compare the effectiveness of the multi-component intervention against usual care for increasing physical activity and reducing falls in community- dwelling older adults. We hypothesize that the multi-component intervention will be more effective as compared to usual care for reducing FoF and falls and increasing physical activity in community- dwelling older adults. Sample size was calculated with reference to effect sizes from meta-analyses by Chua et al. (2019) and Liu et al. (2018), where effect sizes of 0.28 and 0.33 respectively were found. The sample size calculation was based on effect size of 0.3 difference in FoF between the intervention and comparator groups; with power of 80% and significance level of 0.05, 175 patients will be needed in each group. Assuming attrition rate of 20%, 210 participants in each group, or a total of 420 participants, would be needed. Recruitment procedures Recruitment will take place at all National Healthcare Group Polyclinics over a period of 12 months. All healthcare staff including doctors, nurses, physiotherapists and care coordinators (CCs) in recruiting clinics will be briefed about the study and inclusion and exclusion criteria. Potential participants will be recruited on a case encounter basis when they attend at the clinics for follow-up visits. The above-mentioned healthcare staff will refer potential participants who meet the inclusion criteria to any of the study team members. Study team members who encounter suitable potential participants will refer them to another study team member in clinic for recruitment if available, i.e., nurses in study team may cross refer their patients to each other for recruitment. Study team members proficient in potential participants' language will explain the study and clarify any doubts using the Participant Information Sheet, take written informed consent and administer the baseline questionnaire. Data Collection Tools III) Fear of falling (FoF) will be screened using the Single Question on FoF and Activity Restriction (SQ-FAR) and measured using the Short Falls Efficacy Scale - International (FES-I) The SQ-FAR is a single question 'Are you afraid of falling?' used as a screening tool for FoF. It was found to have moderate agreement of 87.8% (Kappa=0.57) with the Falls Efficacy Scale-International (FES-I) in community dwelling adults aged 65 to 70 years old (Belloni et al., 2020). Responses include 'no', 'yes' and 'yes, a lot', 'yes' and 'yes, a lot' indicate presence of FoF. The Short FES-I is a 7-item measure of "fear of falling" and has been demonstrated to have good reliability and validity (Hauer et al., 2010). It was also evaluated in Malaysia and showed good internal consistency, test-retest reliability, construct validity, and responsiveness, with Cronbach's alpha of 0.905 and intraclass correlation coefficient 0.997 for the English version (Tan et al., 2018). Scores are calculated by totaling responses for each item, with a range from minimum 7 (no concern about falling) to maximum 28 (severe concern about falling). 7 to 8 points indicates low concern, 9 to 13 indicates moderate concern and 14 to 28 indicates high concern. Permission to use Short FES-I was obtained from Professor Chris Todd https://sites.manchester.ac.uk/fes-i/ IV) Physical Activity levels will be measured using the Incidental and Planned Exercise Questionnaire: Weekly Average (IPEQ -WA) The IPEQ consists of 10 questions which measure type and amount of physical activity and provides estimates of the frequency and duration of planned exercise and day-to-day activities. Validation in a population of older adults showed that IPAQ-WA had excellent test-retest reliability, with intraclass correlation coefficient 0.87 and was able to discriminate differences in physical activity levels between groups differentiated by sex, age and fall risk factors (Delbaere et al., 2010). Total time spent is summed across all components and expressed as hours per week. The score is derived from multiplying frequency score and duration score to create a total duration for the week score. Permission to use the questionnaire was obtained from Associate Professor Kim Delbaere https://www.neura.edu.au/research-clinic/fbrg/resources/ Statistical and analytical plans Demographic and clinical data, falls, FoF scores and (IPEQ-WA) scores will be reported using descriptive statistics. Paired t-test will be used to compared the differences in FoF scores, number of falls and IPEQ-WA scores pre and post intervention. Independent t-test will be used to compare differences in FoF score, number of falls and IPEQ-WA scores in intervention group and comparator group at 3 months and 6 months post intervention. Ethical considerations Informed Consent Attending healthcare professionals will refer eligible participants to members of the study team on the day of the clinic visit. Trained study team members proficient in potential participants' language will explain the study and clarify any doubts using the Participant Information Sheet. Participants will be given the information sheet about the research study and informed that they could withdraw from the study anytime. The contact details of the PI and DSRB would be given to them to allow them to raise any queries regarding the study. Potential participants will be given adequate time to consider before making a decision whether or not to participate. If the individual fulfils the inclusion criteria and agrees for research participation, written consent will be taken. Confidentiality of Data and Patient Records Hard copy data will be stored in designated locked cabinet(s) or room(s). Electronic data will be stored in a secured computer that is password protected. All hard copy or electronic data will be accessible to authorized study team members only. ;
