Development and validation of an Online Comprehensive Geriatric Screening (O-CGS) Tool.

Area of Science:

• Gerontology
• Digital Health
• Geriatric Medicine

Background:

• Digitalization is transforming healthcare, offering opportunities to improve older adult well-being.
• Developing effective digital tools is crucial for enhancing geriatric care.
• Intrinsic capacity declines in older adults require accessible screening methods.

Purpose of the Study:

• To develop an online comprehensive geriatric screening (O-CGS) tool.
• To evaluate the validity and usability of the O-CGS tool for detecting intrinsic capacity declines in older adults.

Main Methods:

• 381 Thai adults aged 55+ completed an online self-administered O-CGS followed by face-to-face assessments.
• Convenience sampling was used at a university hospital in Bangkok.
• Statistical measures including sensitivity, specificity, and accuracy were calculated.

Main Results:

• The O-CGS tool demonstrated varied sensitivity (48%-100%) and specificity (54%-98%) across different geriatric syndromes.
• The online cognitive screening component showed acceptable performance for mild and severe cognitive impairment (61% sensitivity, 63% specificity).
• Participants completed the O-CGS in an average of 37 minutes and reported high satisfaction (4.4/5).

Conclusions:

• The self-administered O-CGS tool exhibits satisfactory performance and feasibility.
• The O-CGS tool aligns with the principles of healthy aging.
• Digital screening tools can effectively support geriatric health assessments.
