- 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 Scale6-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) TestStandardised 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 functional mobility assessment for frail elderly patients in hospital. Assesses lying to sitting, sitting to lying, sitting balance, standing, gait, transfer, and walking distance. 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 (MNA)Screens for malnutrition risk in elderly patients (>=65 years). Validated MNA-Short Form for rapid screening in clinical settings.
- 4AT Delirium Assessment ToolRapid bedside tool to assess for delirium in older adults. Does not require prior training. Score >=4 indicates likely delirium.
- STRATIFY Falls Risk ScoreIdentifies inpatients at risk of falling using 5 clinical questions. STRATIFY is widely used in UK hospitals for falls prevention planning.
- Polypharmacy Risk Assessment (Beer Criteria)Identifies high-risk medication burden in elderly patients. Based on American Geriatrics Society Beers Criteria and STOPP/START framework.
- Caregiver Strain Index (CSI)Screens for significant caregiver strain in family members of ill or elderly patients. Score >=7 indicates high strain and need for support.
- 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 TestBrooke & 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 Assessment16-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 Living8-domain self/informant rating of higher-order daily function (Lawton & Brody 1969). Original female 0–8; for men, food preparation/housekeeping/laundry typically excluded — score 0–5. Lower = greater dependence.
- Hendrich II Fall Risk ModelHospital inpatient falls risk screening (Hendrich 2003). Sums 8 weighted variables. Score ≥5 = high risk; trigger falls-prevention bundle.
- PRISMA-7 Frailty Screening Tool7-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 Risk6-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 Survey13-item self-report screen for vulnerability in community-dwelling adults ≥65 (Saliba 2001). Higher score = greater functional decline / mortality risk. Score ≥3 indicates 4× greater risk of death or functional decline over 2 years.
- Katz Index of Independence in Activities of Daily Living6-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 patient self-report and informant observation (Alexopoulos 1988). Each item 0 (absent), 1 (mild/intermittent), 2 (severe). Total 0–38. Score ≥8 suggests probable depression.
- 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 ScaleFirst standardised pressure-injury risk score (Norton 1962). Five domains each 1–4. Total 5–20 (lower = higher risk). Score ≤14 = at risk; ≤12 = high risk.
- MUST — Malnutrition Universal Screening ToolFive-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 ScreeningESPEN-endorsed inpatient nutritional risk screen (Kondrup 2003). Combines impaired nutritional status + severity of disease, with age adjustment.
- Fried Frailty PhenotypeFive-criterion physical frailty model (Fried/Cardiovascular Health Study 2001). Patient meeting ≥3 criteria = frail; 1–2 = pre-frail; 0 = robust.
- Electronic Frailty Index (eFI) BandsUK 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.
