What are the most important geriatric assessment tools?

The most important geriatric assessment tools include: the Katz ADL Index and Barthel Index for basic activities of daily living, the Lawton IADL Scale for instrumental ADLs needed for community living, the Geriatric Depression Scale (GDS-15) for depression screening, the MoCA or MMSE for cognitive screening, the Clinical Frailty Scale or Edmonton Frail Scale for frailty assessment, the SPPB for physical performance, and the Falls Efficacy Scale International (FES-I) for fear of falling. Together these form a comprehensive geriatric assessment (CGA).

What is the best frailty assessment tool?

The best frailty tool depends on clinical context. The Clinical Frailty Scale (CFS) is fastest (1–2 minutes, single descriptor) and widely used in emergency, ICU, and surgical settings. The Edmonton Frail Scale (EFS) takes 10–15 minutes but assesses 9 domains including cognition (clock drawing) and physical performance (TUG), making it more informative for care planning. Both use a cut-off of 5 (CFS) or 7 (EFS) to confirm frailty. The SPPB is the best tool for objective lower extremity physical performance measurement.

What is the difference between Katz ADL and Lawton IADL?

The Katz ADL Index measures basic physical self-care activities (bathing, dressing, toileting, transferring, continence, feeding) — the six foundational skills for physical survival. The Lawton IADL Scale measures instrumental activities required for independent community living (telephone, shopping, meal preparation, housekeeping, laundry, transportation, medications, finances). IADL impairment typically precedes ADL impairment and is more sensitive to early cognitive decline. Both should be used together for a complete functional assessment.

What is the GDS-15 cut-off score for depression?

The GDS-15 cut-off score for a positive depression screen is 5 points or above. Scoring ranges: 0–4 = no depression (normal); 5–8 = mild depression; 9–11 = moderate depression; 12–15 = severe depression. At the cut-off of 5, the GDS-15 has a sensitivity of 81% and specificity of 78% for detecting depression in adults aged 65 and older (Sheikh & Yesavage, 1986). A positive screen requires further clinical assessment — it does not constitute a diagnosis.

What is a normal MoCA score?

A MoCA score of 26 or above (after applying the education adjustment of +1 for ≤12 years education) is considered normal. Scores of 18–25 indicate mild cognitive impairment (MCI), 10–17 indicate moderate cognitive impairment consistent with moderate dementia, and below 10 indicates severe cognitive impairment. The MoCA has a sensitivity of 90% and specificity of 87% for detecting MCI at the cut-off of 26 (Nasreddine et al., 2005).

Mood & Cognition

Depression and cognitive screening are the two most critical components of comprehensive geriatric assessment (CGA). The GDS-15 is the validated standard for depression screening in adults aged 65 and above — required for Medicare Annual Wellness Visits and included in the SNF Minimum Data Set (MDS 3.0). The MoCA Score Calculator interprets results from the official MoCA® test form, offering 90% sensitivity for mild cognitive impairment (MCI) versus only 18% for the MMSE. The SMMSE (Molloy & Clarnette) provides a fully standardised, publicly available cognitive screening tool when the proprietary Folstein MMSE cannot be used.

Functional Independence

Functional independence assessment determines care needs, rehabilitation goals, and eligibility for home health and skilled nursing benefits. The Katz ADL Index (6 basic self-care activities) and Lawton IADL Scale (8 community living activities) are used together to capture the full functional picture — the Katz identifies who needs physical care, the Lawton identifies who can live independently in the community. The Barthel Index adds graduated scoring across 10 activities (maximum 100), making it the gold standard for tracking functional recovery in stroke rehabilitation. All three are included in the SNF Minimum Data Set.

Frailty Assessment

Frailty assessment identifies older adults at highest risk of adverse outcomes from illness, surgery, and hospitalisation. The Clinical Frailty Scale (CFS) is the fastest frailty tool (1–2 minutes, single global rating 1–9) and is widely used in emergency departments, ICUs, and surgical preadmission. Frailty is confirmed at CFS ≥ 5. The Edmonton Frail Scale (EFS) takes longer but uniquely combines cognitive screening (clock drawing), physical performance (TUG), and multi-domain health assessment — making it the preferred tool when detailed frailty profiling is needed for care planning. EFS frailty threshold: ≥ 7.

Physical Performance

Objective physical performance measurement predicts disability, falls, nursing home admission, and mortality in older adults more accurately than self-report. The SPPB (Short Physical Performance Battery) combines three timed tests — balance, gait speed, and chair stands — into a 0–12 score that predicts all-cause mortality with a hazard ratio of 1.9–2.4 for the lowest versus highest quartile. A score ≤ 9 identifies high-risk individuals requiring intervention. The Falls Efficacy Scale International (FES-I) addresses the psychological dimension of fall risk — fear of falling affects 25–55% of older adults and predicts future falls, activity restriction, and social isolation even in those who have never fallen.

Geriatric Assessment — Clinical Reference Guide

Geriatric assessment calculators are validated screening and outcome measurement tools used to quantify function, cognition, mood, frailty, and fall risk in older adults aged 65 and above. A Comprehensive Geriatric Assessment (CGA) is a multidisciplinary diagnostic process that evaluates the medical, functional, psychological, and social capabilities of an older person to develop a coordinated plan for treatment and long-term follow-up. The calculators on this page cover all major CGA domains and are designed for use by clinicians across geriatric medicine, primary care, physical therapy, occupational therapy, nursing, and allied health.

Geriatric Assessment in US Clinical Practice

In the United States, geriatric outcome measures are required documentation for several Medicare and Medicaid programmes. The Annual Wellness Visit (AWV) requires depression screening (GDS-15 meets this requirement) and cognitive impairment screening (MoCA or MMSE). The SNF Minimum Data Set (MDS 3.0) requires Katz ADL, GDS-15, MMSE or cognitive interview, and fall risk assessment for all Medicare and Medicaid skilled nursing facility residents. The Medicare Home Health Outcome and Assessment Information Set (OASIS) requires ADL functional assessment using items from the Barthel and Katz frameworks. Having objective, documented scores from validated tools supports insurance authorisation, discharge planning, and skilled care justification.

When to Refer for Comprehensive Geriatric Assessment

A full multidisciplinary CGA is indicated when screening tools identify significant impairment. Consider CGA referral for: GDS-15 ≥ 5 (positive depression screen); MoCA ≤ 25 (possible MCI); Katz ADL ≤ 4 (dependent in 2+ ADLs); CFS ≥ 5 or EFS ≥ 7 (frailty confirmed); SPPB ≤ 9 (low physical performance); or FES-I ≥ 28 (high fall concern with likely activity restriction). Any single positive screen in a high-risk older adult warrants further clinical evaluation and, where available, geriatric specialist review.
