About

Background: Falls are the leading cause of injury among older adults in Singapore, but falls among the elderly can be preventable and the risks are predictable. Translating this understanding of falls etiology into an integrated clinical and public health program that is accessible to the elderly is a critical health services delivery challenge.

Hypothesis: An evidence-based program of screening, risk modification and physical therapy delivered in a community setting will reduce recurrent falls incidence among a high-risk group of elderly recently discharged to the community.

Methodology: This randomized controlled trial targets patients seen at Emergency Department (ED) for a fall or fall-related injuries who are at least 65 years old and will be discharged to home. Upon signing the informed consent form, the participants will be followed up for nine months from the baseline assessment during which the participants are randomized into either a control or the intervention group. The participants in the intervention group will be provided with a multifactorial program of screening, risk modification and physical therapy focused on progressive strength, balance, and gait training either as an individualized program or a group setting in the community for the first three months from the date of randomization. The number of recurrent falls will be monitored via a falls prevention diary maintained by (or for) each participant.

Full description

Objective:

To develop and demonstrate the feasibility and effectiveness of a multifactorial, community-based falls prevention program of screening, risk modification, and progressive physical therapy that targets vulnerable elderly Singaporeans at high-risk of falls.

Methodology:

This two-year, multi-center, two-arm, parallel group, randomized controlled trial will be divided into three phases: (1) pre-study, (2) intervention, and (3) analysis.

During the pre-study phase, overseas experts will train local physiotherapists and community health workers on how to administer and deliver the falls prevention program. Engaging hospital-based physiotherapists to deliver the home-based assessments and exercise programs will maximize the likelihood of long-term sustainability of the intervention program. In addition, manuals will be developed for physiotherapists to guide the evaluation risk factor assessments, home environment assessments, appropriate referrals to different health care providers, and selection of exercise programs that will be progressive, challenging and of optimal intensity and durations. Manuals for risk factor assessments will be shared with the blinded assessors.

The intervention phase will be divided into two phases: a three-month "Active Intervention Phase" and a six-month "Maintenance Phase." In the beginning of the active intervention phase, the participants in the intervention group will receive a detailed falls risk assessment at the baseline assessment by a physiotherapist. The risk factors that will be assessed are the following:

Poor vision: Referral to ophthalmologist for correction
Polypharmacy: Referral to AIC for management of medications if use of five or more medications
Environmental Hazards: Caregiver education and suitable recommendations according to the CDC guidelines to modify risk such as removal of rugs, change to safer footwear, use of non-slip bath mats, additional lighting at night.
Deficiencies in gait, balance or mobility: Physiotherapist-supervised program of gait training, balance and strengthening exercises In the analysis phase, the collected data will be analyzed. The primary outcome measure of the study is the number of fallers over the entire study period. The number of falls will be captured by a falls prevention diary maintained by (or for) each participant.

Procedures:

The elderly seen at ED for a fall or fall-related injury will be screened for participation of the study. Once the consent is taken, all study participants will be given an assessment by a physiotherapist at baseline which assesses sociodemographic characteristics, functional status measured by the Short Physical Performance Battery (SPPB), two-minute walk test, history of falls, cognitive impairment measured by the Montreal Cognitive Assessment (MoCA), quality of life (EQ-5D-5L and EQ-VAS), health care utilization, and medical history (polypharmacy, orthostatic vital signs, and self-reporting eyesight and hearing).

At the end of baseline assessment, the participants will be assigned either a control or the intervention group. Before the start of the exercise sessions, the participants in the intervention group will. Need to complete Physical Activity Readiness Questionnaire (PAR-Q) and a medical evaluation by a physician to ensure that the participants are fit for physical activity. Based on the SPPB score at baseline assessment, participants will be categorized as either high-risk (SPPB<6) or low-to-moderate-risk (SPPB>6) for falls. High-risk patients will be given an individualized PT-supervised program of physical therapy that specifically targets impairments that interfere with engaging in exercise in group setting. The goal of the tailored physical therapy sessions is to modify impairments and transition these patients to an evidence-based exercise program. Low-to-moderate-risk patients will be directly enrolled into an evidence-based group exercise program. The group exercise programs will be offered as one-hour sessions, twice weekly over the intervention period. At the end of the active intervention phase, these participants will transition to a maintenance phase in which they will be encouraged to continue with the exercise on their own and will also be referred to the Health Promotion Board's STEP program.

The participants will be asked at the end of the active intervention phase (three months from the date of randomization) and at the end of the study period (nine months from the date of randomization) about their functional status, history of falls, cognitive impairment, quality of life, health care utilization, and medical history by the blinded assessors. Recurrent falls incidence will be monitored by participants' self-reporting monthly falls diary as well as monthly phone calls conducted by the study coordinator during the entire study period.
