Sponsored by Nova Scotia Health Authority · Not applicable, Interventional, and Health services research
This study evaluates the feasibility and acceptability of implementing the electronic Comprehensive Geriatric Assessment (eCGA) in primary care for adults aged 65 years and older. The study examines how frailty changes over 12 months, how patient self-assessments compare with physician assessments, and how patients perceive the value of the eCGA when used as part of routine care.
The study also includes an interventional randomized sub-study (PAHA), in which eligible participants receive a personalized physical activity program developed by a Clinical Exercise Physiologist. Participants are randomized to either an immediate-start or delayed-start exercise group, allowing assessment of the effects of a tailored activity intervention on frailty, physical activity participation, and goal attainment.
Findings will inform how eCGA tools and personalized activity interventions can be integrated into primary care to support healthy aging and frailty management.
This study investigates the use of the electronic Comprehensive Geriatric Assessment (eCGA) in primary care as a structured approach to identifying frailty, monitoring change over time, and informing individualized care planning for older adults. The eCGA is an electronic adaptation of the Comprehensive Geriatric Assessment used in geriatric care, integrated into the TELUS electronic medical record used in Nova Scotia. Embedding the eCGA directly within the EMR is designed to improve feasibility and uptake by allowing primary care physicians to efficiently review key domains of mobility, cognition, mood, comorbidities, medications, and daily function during routine care encounters to generate a frailty index (FI).
The main study is a prospective, longitudinal cohort conducted in a primary care clinic. Up to 120 adults aged 65 and older will complete baseline eCGA assessments, patient-reported frailty and health questionnaires with follow-up at 12-months. We will investigate changes in frailty status, concordance between physician and patient frailty assessments (eCGA Frailty Index, Clinical Frailty Scale, Pictorial Fit-to-Frail Scale, Health Questionnaire - Frailty Index), patient experiences with the eCGA process, and health service utilization. Quantitative analyses include descriptive statistics, paired comparisons, one-way ANOVA models, correlation analyses, and regression models to identify predictors of frailty change. Qualitative semi-structured interviews will explore participants' perspectives on the acceptability and perceived clinical value of the eCGA.
The study also includes a randomized interventional sub-study-the Personalized Approach for Healthy Aging (PAHA). Sixty to 120 participants will be randomized into two groups.
Group AB (Immediate Exercise Group) will receive a tailored physical activity intervention beginning at baseline.
Group BA (Delayed Exercise Group) will receive the same intervention beginning after an initial waiting period.
The intervention is delivered by a Clinical Exercise Physiologist and includes individualized goal setting using Goal Attainment Scaling, a tailored exercise prescription, and structured follow-up contacts (weekly in month 1, biweekly in month 2, then monthly to month 6. This will vary by participant as needed). Randomization is stratified by Clinical Frailty Scale score.
The PAHA sub-study evaluates whether a personalized exercise intervention can improve physical activity levels (Physical Activity Scale for the Elderly), frailty progression, and individualized goals. Mixed-effects models will be used to examine longitudinal changes in activity and frailty, with "time zero" defined as the start of the intervention for each participant. Time points prior to and after the start of the intervention will be analyzed to evaluate treatment effects, carry-over effects, and sequence effects. Participants who withdraw early will still contribute available data, consistent with mixed-model analytic methods.
Safety monitoring is integrated into both clinical practice and the study design. All participants undergo a physician assessment prior to sub-study enrollment; referrals to physiotherapy or occupational therapy occur when clinically appropriate. The Clinical Exercise Physiologist monitors symptoms, adherence, and adverse events at each contact and modifies exercise prescriptions as necessary. All serious adverse events potentially related to the intervention are reviewed by the Principal Investigator and reported in accordance with institutional policy.
Qualitative and quantitative data will be triangulated to provide a comprehensive understanding of the feasibility, acceptability, and potential clinical impact of integrating frailty assessment and tailored physical activity support into routine primary care for older adults.

Exclusion Criteria:
Participants begin the Personalized Approach for Healthy Aging (PAHA) physical activity intervention immediately after basline assessment. The intervention includes individualized goal setting using Goal Attainment Scaling, tailored exercise prescription, and structured follow-up contacts with a Clinical Exercise Physiologist.
Behavioral: Personalized Approach for Healthy Aging (PAHA)
Participants begin the PAHA physical activity intervention after a delayed-start period. They complete the same assessments and receive the same individualized exercise program as Group AB (immediately exercise group) but begin the intervention later in the study.
Behavioral: Personalized Approach for Healthy Aging (PAHA)
A personalized physical activity and behaviour-change program delivered by a Clinical Exercise Physiologist, including individualized goal setting, tailored home-based exercise prescriptions, and structured follow-up contacts (telephone or virtual) over 6 months.
Comprehensive Geriatric Assessment - Frailty Index
A comprehensive geriatric assessment (CGA) of the participants' global health state, including their current and relevant past illnesses, medications, cognition, emotion, motivation, health attitude, communication, sleep, pain, control of life, strength, balance, mobility, activities and instrumental activities of daily living, quality of life, lifestyle, and social engagement are assessed. Information to inform the CGA is derived from participant interviews, structured assessments and tests, and medical record review. Each CGA item will be recoded to a scale from 0 to 1, with 0 representing no deficit and 1 representing the full deficit. The total Frailty Index score will be calculated by dividing the sum of the variables' recoded values (the sum of the deficits) by the number of variables measured for that person. The range of the frailty index score is between 0 and 1, where higher scores indicate greater frailty.
Time frame: Assessed at baseline and at 12-month follow-up.
Health Questionnaire - Frailty Index
The health questionnaire includes questions related to self-rated health, chronic conditions, activities of daily living, instrumental activities of daily living, cognitive function, and mental health. Responses to each question will be coded on a scale from 0 to 1, with 0 representing no deficit and 1 representing the full deficit. The total health questionnaire Frailty Index score will be calculated by dividing the sum of the variables' coded values (the sum of the deficits) by the number of variables measured for that person. The range of the frailty index score is between 0 and 1, where higher scores indicate greater frailty.
Time frame: Baseline and 12-month follow-up.
Clinical Frailty Scale
The Clinical Frailty Scale (CFS) broadly stratifies degrees of fitness and frailty on a 9-point scale where higher scores indicate greater risk: 1-very fit; 2-fit; 3-managing well; 4-living with very mild frailty; 5- living with mild frailty; 6-living with moderate frailty; 7-living with severe frailty; 8- living with very severe frailty; and 9-terminally ill. The score is based on clinical judgment as part of the comprehensive geriatric assessment.
Time frame: Baseline and 12-month follow-up
Pictorial Fit-Frail Scale
This is a brief, picture-based frailty assessment designed so patients, caregivers, or clinicians can rate current health status common across 14 domains (e.g., mobility, function, cognition, mood, nutrition, comorbidity) using simple visual panels. This scale will be completed separately by participants (self-administered version) and health care professionals (PFFS-HCP). For each domain, the level representing least or no impairment (first picture on the left) is scored 0, the next level (second picture from the left) as 1, etc. The minimum score for each domain is 0; the maximum score for each domain ranges from 2 to 5. Total Pictorial Fit-Frail Scale scores are calculated by summing the scores across domains. The final summed score ranges from 0 (no frailty; very fit) to 43 (severely frail).
Time frame: Baseline and 12-month follow-up.
Physical Activity Scale for the Elderly
The Physical Activity Scale for the Elderly (PASE) quantifies the frequency, duration, and intensity of physical activities, and sedentary time. The scale includes 10 questions that collect information about physical activities performed over the past week, including leisure activities, household activities, work, and volunteering (e.g., walking, caring for another person). The responses for each activity are used to calculate a total score. Scores range from 0 to over 400, with higher scores representing greater activity levels. The Physical Activity Scale for the Elderly will be administered by the Clinical Exercise Physiologist. It will only be administered to participants who consent to participate in the sub-study.
Time frame: Group AB: Baseline, 3 months, 6 months, and 12 months Group BA: Baseline, 6 months, 9 months, and 12 months.
Patient acceptability of eCGA
Acceptability of the electronic Comprehensive Geriatric Assessment (eCGA) as reported by participants using an 18-item survey administered post-CGA to assess ease of completion, understanding, perceived usefulness, and overall satisfaction. Each item is scored on a 5-point Likert scale where 1 indicates strong agreement and 5 indicates strong disagreement. The acceptability score will be calculated by summing all item scores. The total score will range from 18 (best outcome) to 90 (worst outcome).
Time frame: Baseline with follow-up at 12-months.
Goal Attainment (PAHA Sub-Study)
Goals are constructed on a 5-point scale ranging from +2 (much better than the expected outcome) to -2 (much worse than the expected outcome), where the participant's baseline status is set as -1 and the expected outcome (i.e., desired goal) is set as 0. Goals are set at baseline with the Clinical Exercise Physiologist who reviews attainment status with participants at each follow-up. Mean Goal Attainment scores and proportion of goals achieved will be reported. Goal Attainment Scaling is individualized in that participants select goal that are personally relevant. Summarizing this individualized information is accomplished using a formula that accounts for the number of goals set and variations in attainment (total score range 17 - 82 with higher scores indicating greater goal achievement).
Time frame: Group AB: Baseline with follow-up at 3-, 6-, and 12-months. Group BA: Baseline with follow-up at 6-, 9-, and 12-months.
Qualitative experience of the eCGA and PAHA
Semi-structured interviews at 12 months will explore participants' experiences of the eCGA process and, for PAHA participants, the personalized exercise program (acceptability, feasibility, perceived benefits, and barriers). Transcripts will be analyzed using thematic analysis to identify key themes informing implementation.
Time frame: Interviews conducted approximately 12 months after baseline.
