Berg Balance Scale (BBS)

14-item functional balance assessment tool for elderly and patients with balance disorders. Each item scored 0–4. Total 0–56. Score <45 = increased fall risk. Widely used in clinical and rehabilitation settings.
Morse Fall Scale

6-item validated fall risk assessment tool for hospitalised patients. Identifies patients at risk of falls for targeted interventions. Score ≥45 = high fall risk.
Clinical Frailty Scale (CFS)

9-level clinical tool for assessing frailty in older adults. Based on clinical judgement integrating mobility, energy, physical activity, and function. Score 1 = very fit; score 9 = terminally ill. Widely used for clinical decision-making.
Timed Up and Go (TUG) Test

Standardised functional mobility test measuring time to rise from a chair, walk 3 metres, turn, and return to sit. Simple and reliable predictor of fall risk and functional mobility in older adults.
Cumulative Illness Rating Scale — Geriatric (CIRS-G)

14-organ-system comorbidity scoring tool designed for older adults. Each system scored 0 (no problem) to 4 (extremely severe). Total score 0–56. Used for risk stratification, research, and clinical decision-making in geriatric medicine.
Nutritional Risk Index (NRI)

Objective nutritional assessment tool using serum albumin and actual versus usual body weight. NRI = (1.519 × serum albumin g/L) + (41.7 × [current weight / usual weight]). Identifies nutritional risk in hospitalised patients, particularly elderly.
Elderly Mobility Scale (EMS)

7-item mobility assessment for frail older people in hospital (Smith 1994): lying to sitting, sitting to lying, sit to stand, stand, gait, 6 m timed walk and functional reach. Score 0–20; used to track recovery and plan discharge.
Clinical Frailty Scale (CFS)

Clinically assesses frailty in adults >=65 years on a 9-point scale from very fit to terminally ill. Predicts adverse outcomes and guides goals of care.
Gait Speed Test (Frailty)

Measures walking speed over 4-5 metres. A powerful predictor of disability, hospitalisation, and mortality in older adults.
Mini-Mental State Examination (MMSE)

Standardised 30-point cognitive screening tool assessing orientation, memory, attention, language, and visuospatial skills. Guides dementia diagnosis and monitoring.
Mini Nutritional Assessment — Short Form (MNA-SF)

Screens for malnutrition risk in elderly patients (>=65 years). Validated MNA-Short Form for rapid screening in clinical settings.
4AT Delirium Assessment Tool

Rapid bedside delirium assessment for older adults; no special training needed. Score ≥ 4 suggests possible delirium; 1–3 possible cognitive impairment.
STRATIFY Falls Risk Score

STRATIFY (Oliver 1997): five questions for older inpatients, 1 point each. Validation studies found limited accuracy — use alongside a multifactorial falls assessment, not alone.
Polypharmacy Risk Assessment (Beers Criteria)

Identifies high-risk medication burden in elderly patients. Based on American Geriatrics Society Beers Criteria and STOPP/START framework.
Caregiver Strain Index (CSI)

Robinson's 13-item Caregiver Strain Index for family and other informal carers. Score 7 or more indicates a high level of strain.
Abbreviated Mental Test Score (AMTS / AMT-10)

10-item bedside cognitive screen for delirium and dementia in older adults (Hodkinson 1972). Score ≤6/10 suggests cognitive impairment and warrants further assessment (e.g. 4AT, CAM, MoCA). Widely used in UK hospital settings and embedded in NICE delirium pathways.
6-CIT — Six-Item Cognitive Impairment Test

Brooke & Bullock (1999) six-item dementia screen. NICE-recommended for use in primary care (NG97). Inverse scoring: errors are summed; total 0–28 with higher score = greater impairment. Score ≥8 suggests cognitive impairment warranting referral.
Tinetti POMA — Performance-Oriented Mobility Assessment

16-item gait and balance assessment (Tinetti 1986). Total /28 (balance /16 + gait /12). Predicts falls risk in community-dwelling older adults. Widely used in UK falls clinics.
Edmonton Frail Scale (EFS)

Multidomain frailty screen (Rolfson 2006). 9 domains, total 0–17. Validated across community and acute settings.
Lawton IADL Scale — Instrumental Activities of Daily Living

8-domain rating of instrumental activities of daily living (Lawton & Brody 1969). Each domain scores 1 or 0 by the level described; total 0 (dependent) to 8 (independent). Score all 8 domains for both men and women (the original scored men on 5). There are no published cut-offs — track change over time.
Hendrich II Fall Risk Model

Hospital inpatient falls risk screening (Hendrich 2003). Sums 8 weighted variables. Score ≥5 = high risk; trigger falls-prevention bundle.
PRISMA-7 Frailty Screening Tool

7-item self/informant-report frailty screen for community-dwelling older adults (Raîche 2008). Validated in primary-care, ED triage and population screening. Score ≥3 indicates frailty and triggers comprehensive geriatric assessment.
ISAR — Identification of Seniors At Risk

6-item ED screening tool for older adults (McCusker 1999) predicting 30-day adverse outcomes (functional decline, readmission, institutionalisation, mortality). Score ≥2 triggers comprehensive geriatric assessment.
VES-13 — Vulnerable Elders Survey

13-item self-report screen for vulnerability in community-dwelling adults ≥65 (Saliba 2001). Higher score = greater functional decline / mortality risk. Score ≥3 indicates 4.2 times the risk of death or functional decline over 2 years.
Katz Index of Independence in Activities of Daily Living

6-item index of basic ADL independence (Katz 1963). Each: 1 (independent) or 0 (dependent). Total 0–6.
Cornell Scale for Depression in Dementia (CSDD)

19-item observer-rated scale of depressive symptoms in dementia, drawing on informant and patient interviews (Alexopoulos 1988). Each item 0 (absent), 1 (mild or intermittent), 2 (severe); total 0–38. Scores above 10 indicate probable and above 18 definite major depression; below 6 usually no significant depressive symptoms.
FAST — Functional Assessment Staging Tool (Reisberg)

7-stage functional staging of Alzheimer-type dementia (Reisberg 1988). Stages 1–7 reflect cognitive and functional decline; stages 7a–7f delineate end-stage dementia. FAST 7a–c is commonly used to determine hospice eligibility (US criteria) but is widely cited internationally for prognostication.
Global Deterioration Scale (GDS / Reisberg)

Seven-stage cognitive staging of Alzheimer-type dementia (Reisberg 1982). Companion to FAST. Drives counselling and care-planning.
Norton Pressure Sore Risk Scale

First standardised pressure-injury risk score (Norton 1962). Five domains each 1–4. Total 5–20 (lower = higher risk). Score ≤ 14 = at risk. Use with clinical judgement (NICE CG179).
MUST — Malnutrition Universal Screening Tool

Five-step BAPEN screening tool (2003). BMI score + unplanned weight loss score + acute disease effect score. Total 0–6 categorised low / medium / high risk.
NRS-2002 — Nutritional Risk Screening

ESPEN-endorsed inpatient nutritional risk screen (Kondrup 2003). Combines impaired nutritional status + severity of disease, with age adjustment.
Fried Frailty Phenotype

Five-criterion physical frailty model (Fried/Cardiovascular Health Study 2001). Patient meeting ≥3 criteria = frail; 1–2 = pre-frail; 0 = robust.
Electronic Frailty Index (eFI) Bands

UK primary-care eFI (Clegg 2016) automatically calculated from 36 deficits in the GP record. eFI = number of deficits present / 36. This calculator records the calculated band — generated by EMIS / SystmOne for adults ≥65 per NHS England Frailty contract.
