Tools for Falls Risk Assessment

Falls assessment tools serve three distinct purposes: (i) screening / case-finding, (ii) risk stratification, and (iii) objective measurement of gait and balance deficits to target intervention and monitor progress.

No single tool is adequate alone. Tools supplement — never replace — a detailed history, medication review, postural blood pressure and targeted physical examination.

The most powerful single predictor is not a scale but a simple question — "Have you fallen in the last one year?" A previous fall is the strongest predictor of a future fall.

STEADI algorithm (Stopping Elderly Accidents, Deaths and Injuries — CDC): a stepwise three-stage approach — Screen → Assess → Intervene. It is the standard framework for community falls screening.

"Three Key Questions" (STEADI):

Have you fallen in the past year?

Do you feel unsteady when standing or walking?

Do you worry about falling? A "yes" to any question triggers full risk assessment.

Stay Independent 12-item questionnaire: a self-administered checklist; a score of ≥4 indicates increased fall risk and mandates further assessment.

AGAIN I'VE FALLEN mnemonic: a bedside checklist for systematic risk-factor identification — Again fallen, Gait/balance problems, ADL loss, Impaired mental status, Number of drugs (>4), Illness/delirium, Vestibular disorders, Eyes/Ears, Foot disorders, Alcohol, Lower-limb weakness, Low BP (postural), Environmental hazards, Neurological disorders.

Gait speed over a pre-measured 4-metre course. 0.6–0.8 m/sec = high-risk range; <0.6 m/sec is the accepted cut-off for abnormal gait. Every 0.1 m/sec fall in speed carries a 7% rise in fall risk. It also predicts disability, hospitalisation, institutionalisation and mortality.

Timed Get Up and Go Test (GUGT / TUG): patient rises from a standard armchair, walks 3 metres (10 feet), turns, returns and sits. Walking aid permitted. >12 seconds = high fall risk (sensitivity 77%, positive predictive value 93% in the community; sensitivity 91% but specificity only 22% in inpatients). Even an untimed observation is clinically useful.

30-Second Chair Stand Test: number of full sit-to-stands in 30 seconds with arms folded across the chest — measures lower-limb strength and endurance.

Four-Stage Balance Test: progressive stances — feet together → semi-tandem → tandem → single leg, each held for 10 seconds. Inability to hold tandem stance for 10 seconds indicates increased fall risk.

Standing unassisted from a sitting position: sensitivity 31%, specificity 90%; risk rises if the person cannot stand or takes more than 2 seconds to do so.

Tinetti Performance-Oriented Mobility Assessment (POMA / Tinetti Mobility Scale): 14 performance tasks split into Balance (0–16) and Gait (0–12), total 0– 28. Score <24 indicates fall risk (mean sensitivity 82%, specificity 65%). Takes 10– 15 minutes — its main drawback in a busy clinic.

Berg Balance Scale (BBS): 14 items, each scored 0–4, total 0–56. Interpretation: 0–20 = wheelchair-bound; 21–40 = walks with assistance; 41–56 = independent. Best suited to rehabilitation and stroke settings.

Short Physical Performance Battery (SPPB): three components — balance (side-by-side, semi-tandem, tandem), 8-foot (2.44 m) walk, and five repeated chair stands — each scored 0–4, total 0–12. Predicts mortality, nursing-home admission and disability in a graded fashion.

Dual-task testing: walking while counting backwards from 100 by sevens, TUG while holding a full glass of water, or one-leg stand with eyes closed. Institutionalised elders who cannot converse while walking are at high fall risk; clinical utility remains uncertain because of variability across studies.

Other balance measures compared psychometrically against TUG include the one-leg (single-limb) stance test and the Functional Reach Test.

Fear of falling: measured with the Falls Efficacy Scale–International (FES-I) and the Short FES-I (7-item); the ABC (Activities-specific Balance Confidence) Scale is an alternative. Fear of falling is an independent predictor of future falls.

Supporting assessments that function as tools:

Postural BP — lying, sitting, and at 1 and 3 minutes standing; fall of >20 mmHg systolic = orthostatic hypotension

Medication review tools — STOPPFall, Beers criteria, STOPP/START

Home hazard tools — HOME FAST, occupational-therapist home safety checklists

Vision/hearing — Snellen chart, whispered voice test, Hearing Handicap Inventory for the Elderly

Cognition/mood — MMSE/MoCA/SLUMS, GDS (dementia and depression both raise fall risk)

Hospital and institutional fall risk scales (used mainly by nursing services for care planning):

Morse Fall Scale (MFS) — 6 items, score 0–125; ≥25 moderate, ≥45 high risk; most widely used in acute care

STRATIFY (St Thomas's Risk Assessment Tool in Falling Elderly Inpatients) — 5 items; score ≥2 = at risk

Hendrich II Fall Risk Model — 7 items including a Get-Up-and-Go component and confusion/depression; score ≥5 = high risk

Johns Hopkins Fall Risk Assessment Tool (JHFRAT)

NICE NG249 (April 2025) — a major reversal on risk-prediction tools. The guideline replaces CG161 (2013) and covers everyone aged 65 and over plus people aged 50–64 at higher risk. It explicitly recommends against using formal falls risk-prediction tools. Clinicians should instead directly ask everyone ≥65 (and 50–64 with risk-enhancing conditions such as dementia, arthritis, Parkinson's disease, stroke, diabetes or learning disability) about any fall in the past year, opportunistically at routine appointments and annual health checks. Those with defined criteria — including two or more falls in the last year — go straight to a comprehensive falls assessment; those who fell once without these criteria have their gait and balance assessed.

World Falls Guidelines — the three-tier stratification model. Older adults are placed in low risk (education, general exercise), intermediate risk (targeted exercise or physiotherapy referral for balance and strength) or high risk (full multifactorial falls risk assessment with individualised interventions), determined either by opportunistic case-finding or at presentation with a fall. High-risk markers are recurrent falls, injurious falls, frailty and balance problems.

Real-world testing of the World Guidelines algorithm (BMC Geriatrics 2024). In 392 emergency-department patients assessed by a frailty intervention team, almost all fell into the high-risk (43.4%) or low-risk (38.0%) groups with only 4.8% intermediate, suggesting the intermediate criteria need widening. Hearing loss and dizziness were significantly associated with falls, whereas vision and balance were not, supporting formal inclusion of sensory measures in the algorithm.

Proposed algorithm refinement (Age and Ageing, 2025). Broader use of the TUG test with a shorter cut-point of 10 seconds stratified a community sample into three sizeable, distinct risk groups, allowing more timely and appropriately tailored prevention.

USPSTF 2024 — the accuracy gap in existing tools is now formally acknowledged. In response to public comment on its 2024 falls statement, the USPSTF agreed that more accurate risk assessment tools are needed and listed the development and validation of primary-care-feasible tools that accurately predict fall risk as a formal research gap.

Inpatient scales perform poorly in older patients. A large retrospective study (2024; 303 fall events vs 47,146 non-fall events) found the Hendrich II model at its standard cut-off ≥5 had sensitivity of only 29.5%, specificity 86.3% and AUC 0.57 — limited discriminative ability. Lowering the cut-off to ≥2 raised the AUC to 0.75 and identified 101 additional fall events, showing that cut-off selection matters more than the tool itself. In the same analysis, STRATIFY failed to predict falls in geriatric wards and in those aged ≥75 years, and MFS and JHFRAT showed lower sensitivity and specificity than Hendrich II.

Two-stage screening models under evaluation (International Nursing Review, 2025). The Morse Fall Scale showed higher specificity and performed well in surgical wards (AUC 0.887) and in patients aged ≥75 (AUC 0.837), while a Clinical Judgment Method offered higher sensitivity for rapid screening; a combined "screening–confirmation" two-stage model is proposed but not yet validated.

Indian evidence for tool selection. LASI wave-1 analyses show that poor grip strength, slow gait speed, ADL limitation, depression and sensory impairment are independent determinants of falls in Indian elders — supporting the use of grip strength, gait speed, GDS and simple sensory screening as the core, low-cost battery in Indian NPHCE geriatric clinics, where formal balance laboratories are unavailable.

STOPPFall as the standard medication-side tool. A validated Delphi-derived list of 14 fall-risk-increasing drug classes, mostly psychotropics, combined with stepwise practical deprescribing guidance for medication review.

Emerging technology. Wearable inertial sensors, smartphone-based TUG, instrumented gait analysis and machine-learning models are being developed to replace static questionnaires, but none has yet entered guideline recommendations.
