Abstract

BACKGROUND: Globally, it is estimated that the geriatric population will double in the coming 30 years. In Pakistan, people over 65 are more than 15 million, and it is estimated to reach 40 million by 2050, which will be around l2%o of the total population. Holistic geriatric assessment is designed to cover the needs of the senior citizens, which includes multiple morbidities, cognitive changes, functional status, risk of fall, and polypharmacy. There multiple tools to assess geriatric problems however, this study aims to create and authenticate tool that focuses on formative assessment of trainees on a detailed and comprehensive assessment of geriatric patients.
METHODOLOGY: The pilot study for tool validation is commenced at the Department of Family Medicine, Aga Khan University, Pakistan. The comprehensive geriatric assessment tool (CGAT) for the residents was developed with seven domains and twenty-seven items. This tool then underwent the process of content validation by six experts. All family medicine residents (n:16) were evaluated on their interaction with an elderly standardized patient by three independent evaluators applying this tool. Data was analyzed using STAT14.0. The internal consistency was measured through Cronbach's Alpha. Inter-rater reliability was assessed using Interclass Correlation Coefficient (ICC). Performances of junior residents (Year 1 and2) and senior residents (Year 3 & 4) were compared for item-based scores using an independent sample t-test.
Results:Content validity index for clarity, comprehensiveness, and relevance of the tool was 0.88. Cronbach's alpha was 0.944. The interclass Correlation Coefficient (ICC) of the item-based rating scale and global ratings scale was found to be good (0,849). The F-test confirms the ICC was statistically significant(p = 0.000), meaning raters distinguished between residents consistently. Though the senior resident (Year 3 &4) performed better than the junior residents (Year I &.2), it was not statistically significant.
Conclusion: The newly developed comprehensive geriatric assessment tool has excellent content validity and high reliability (internal consistency), reflecting the tool’s strength in measuring key competencies
