17.4 Falls Risk Assessment (STRATIFY), Ergonomics & Manual Handling
Key Takeaways
- Inpatient falls represent the most prevalent patient safety incident in Irish acute hospitals, requiring mandatory risk screening within 6 hours of admission using validated tools such as STRATIFY (score ≥ 2 indicates high risk).
- Bed rails must never be used routinely as a falls prevention measure; when applied to restrict a patient's voluntary freedom of movement, they constitute a physical restraint requiring comprehensive risk-benefit assessment, multidisciplinary consensus, and strict monitoring.
- Following an inpatient fall, nurses must follow a strict post-fall algorithm: do not move the patient immediately; perform a primary survey (ABCDE), immobilise the cervical spine if head strike is suspected, examine for fractures, obtain INEWS vitals, and await medical assessment before hoisting or mobilizing.
- Under the Safety, Health and Welfare at Work Act 2005 and General Application Regulations 2007, manual lifting of dependent adult patients is prohibited; nurses must conduct a TILE risk assessment and utilize mechanical handling aids (slide sheets, active/passive hoists).
Falls Risk Assessment (STRATIFY), Ergonomics & Manual Handling
Core Safety Insight: Inpatient falls account for over 30% of all reported clinical incidents in Irish healthcare, contributing to serious physical trauma (notably fractured neck of femur and intracranial haemorrhage), functional decline, and fear of falling. Effective fall reduction is directed by the HSE National Strategy for the Prevention of Falls and Fractures in Ireland's Older People, paired with ergonomic compliance under the Safety, Health and Welfare at Work Act 2005.
Falls Risk Assessment & Screening: The STRATIFY Tool
Every adult patient admitted to an acute hospital in Ireland must undergo a validated falls risk assessment within 6 hours of admission, repeated weekly, and immediately re-evaluated after any fall or significant clinical change.
The STRATIFY Assessment Tool
The STRATIFY (St Thomas's Risk Assessment Tool in Falling Elderly Inpatients) scale is one of the most widely validated and utilized screening instruments in Irish clinical practice. It scores five distinct clinical criteria on a binary (0 or 1) basis:
+-----------------------------------------------------------------------------+
| THE STRATIFY FALLS RISK ASSESSMENT TOOL |
+---+---------------------------------------------------------+---------------+
| # | ASSESSMENT QUESTION / CLINICAL PARAMETER | SCORE (0 or 1)|
+---+---------------------------------------------------------+---------------+
| 1 | PREVIOUS FALL: Did the patient present with a fall, or | Yes = 1 |
| | has the patient fallen in the hospital or past 3 months?| No = 0 |
+---+---------------------------------------------------------+---------------+
| 2 | AGITATION / COGNITION: Is the patient agitated, | Yes = 1 |
| | confused, or disoriented to person, place, or time? | No = 0 |
+---+---------------------------------------------------------+---------------+
| 3 | VISUAL IMPAIRMENT: Is the patient visually impaired to | Yes = 1 |
| | the extent that everyday function is severely affected? | No = 0 |
+---+---------------------------------------------------------+---------------+
| 4 | FREQUENT TOILETING: Does the patient have urgent, | Yes = 1 |
| | frequent, or uncontrolled toileting needs / diarrhoea? | No = 0 |
+---+---------------------------------------------------------+---------------+
| 5 | MOBILITY & TRANSFER: Is the patient's combined transfer | Yes = 1 |
| | (bed-to-chair) and mobility score impaired or unsafe? | No = 0 |
+---+---------------------------------------------------------+---------------+
| TOTAL STRATIFY SCORE (Range: 0 to 5) | >= 2 = HIGH |
+-------------------------------------------------------------+---------------+
Clinical Interpretation
- Score 0 to 1: Low to Moderate Risk — Implement universal falls precautions (clutter-free environment, accessible call bell, appropriate footwear).
- Score ≥ 2: High Risk of Falling — Mandates an individualised multidisciplinary falls care plan, red risk identifier wristband, comfort rounds, and targeted environmental interventions.
Multifactorial Risk Factors
Falls result from complex interactions between intrinsic physiological vulnerabilities and extrinsic environmental hazards:
- Intrinsic Factors: Advanced age (≥65 years), cognitive impairment (dementia, delirium), sensory deficits, postural (orthostatic) hypotension (defined as a drop in systolic BP ≥20 mmHg or diastolic BP ≥10 mmHg within 3 minutes of standing), peripheral neuropathy, arthritis, urinary urgency/incontinence, and polypharmacy (particularly "culprit drugs": benzodiazepines, antipsychotics, antidepressants, opioids, diuretics, and antihypertensives).
- Extrinsic Factors: Dim lighting, cluttered walking pathways, wet or highly polished floors, call bells placed out of patient reach, inappropriate bed height, trailing IV tubing or catheter bags, and poor footwear (backless slippers, smooth soles, or walking in socks).
Multi-Component Falls Prevention Interventions
- Low-Low Profiling Beds & Floor Crash Mats: For patients with severe cognitive impairment or restlessness who attempt to climb out of bed, lower the electric profiling bed to its minimum height (inches from floor) and place high-density impact-absorbing crash mats along the bedside.
- Intentional Rounding ("The 4 Ps"): Registered nurses and HCAs conduct structured comfort rounds every 1 to 2 hours:
- Pain: Assess comfort and administer prescribed analgesia.
- Position: Assist with turning and comfortable alignment.
- Potty: Proactively assist with toileting before urgency precipitates unassisted climbing.
- Possessions: Ensure call bell, water jug, reading glasses, and walking aids are placed securely within arm's reach.
- Safe Footwear: Ensure well-fitting shoes with non-skid rubber soles and supportive heel counters, or hospital-issued grip socks. Strictly prohibit bare feet, open-backed slippers, or standard socks.
- Sensor Alarm Mats: Wireless pressure-sensitive bed or chair alarm mats notify nursing staff when an unassisted high-risk patient begins to stand.
Bed Rails: Safety Devices vs Physical Restraint
In Irish healthcare, bed rails (cot sides) are governed by the Department of Health National Policy on Towards a Restraint-Free Environment in Nursing Homes and Hospitals and NMBI guidelines.
+-----------------------------------------------------------------------------+
| BED RAILS: CLINICAL RISK-BENEFIT MATRIX |
+------------------------------------+----------------------------------------+
| LEGITIMATE CLINICAL INDICATIONS | SEVERE RISKS & RESTRAINT HAZARDS |
+------------------------------------+----------------------------------------+
| - Prevents accidental roll-out in | - Patient climbing over rails: fall |
| unconscious, heavily sedated, or | height increases by 3-4 feet, leading|
| completely immobile patients | to catastrophic intracranial injury |
| - Provides sensory boundary on | - Entrapment of head, neck, or limbs |
| specialised air mattresses | between rail bars (asphyxiation risk)|
| - Patient explicitly requests them | - Agitation, fear, and delirium |
| for bed turning assistance | exacerbated by feeling "caged in" |
+------------------------------------+----------------------------------------+
[!CAUTION] The Restraint Determination: If bed rails are raised with the intention of restricting a mobile, confused patient from voluntarily getting out of bed, they are legally classified as a Physical Restraint. Bed rails must NEVER be used as a routine fall prevention measure. Restraint application requires documented medical order, capacity assessment, multidisciplinary consensus, exploration of all least restrictive alternatives (e.g., low-low bed, floor mat, sensor alarm), family consultation, and frequent recorded safety checks.
Post-Fall Management Protocol (HSE Algorithm)
When an inpatient fall occurs, healthcare staff must execute the standardized HSE Post-Fall Clinical Pathway without delay:
+-----------------------------------------------------------------------------+
| HSE POST-FALL CLINICAL PATHWAY |
+-----------------------------------------------------------------------------+
| 1. IMMEDIATE ACTION: DO NOT MOVE THE PATIENT! |
| - Keep patient resting flat on the floor in situ |
| - Check environment for immediate hazards; reassure patient |
+-----------------------------------------------------------------------------+
v
| 2. PRIMARY SURVEY (ABCDE) & CERVICAL SPINE IMMOBILISATION |
| - Assess Airway, Breathing, Circulation, Disability (AVPU/GCS), Exposure |
| - If fall was UNWITNESSED, head strike occurred, or neck pain present: |
| Maintain manual in-line cervical spine stabilisation! |
+-----------------------------------------------------------------------------+
v
| 3. SECONDARY SURVEY: SYSTEMATIC INJURY EXAMINATION |
| - Inspect skull for lacerations, haematomas, "battle's sign", raccoon eyes|
| - Palpate clavicles, ribs, pelvic ring, and spine |
| - Check lower limbs: Shortening and external rotation indicates |
| FRACTURED NECK OF FEMUR (#NOF) |
+-----------------------------------------------------------------------------+
v
| 4. VITAL SIGNS & NEUROLOGICAL BASELINE |
| - Full INEWS vital signs (HR, BP, RR, SpO2, Temp) |
| - Check Capillary Blood Glucose (rule out hypoglycaemia) |
| - Record GCS and pupillary size/reactivity |
+-----------------------------------------------------------------------------+
v
| 5. MEDICAL REVIEW & SAFE TRANSFER |
| - Urgent medical team examination BEFORE moving if injury is suspected |
| - Transfer using mechanical lifting equipment (e.g., scoop stretcher, |
| HoverJack air transfer, or mobile floor hoist with lifting sling) |
| - NEVER PERFORM A MANUAL DEAD-LIFT FROM THE FLOOR! |
+-----------------------------------------------------------------------------+
v
| 6. POST-FALL GOVERNANCE & OBSERVATIONS |
| - 24-hour Neurological Observations (GCS, pupils, vitals) if unwitnessed |
| fall, head strike, or patient is receiving anticoagulants |
| - Re-evaluate STRATIFY score, update care plan, log on NIMS, inform family|
+-----------------------------------------------------------------------------+
Manual Handling & Ergonomics in Nursing
Musculoskeletal disorders (especially lumbar strain and disc herniation) represent the primary cause of occupational disability among nurses. Nursing practice in Ireland is governed by the Safety, Health and Welfare at Work Act 2005 and the Safety, Health and Welfare at Work (General Application) Regulations 2007 (Chapter 4 of Part 2: Manual Handling of Loads).
The "No Manual Lifting" Policy
Irish healthcare facilities enforce an explicit No Manual Lifting Policy for dependent adult patients. Manually lifting a patient's full body weight without mechanical equipment is unsafe, illegal, and unacceptable practice.
The TILE Ergonomic Assessment Framework
Prior to conducting any manual handling intervention, the nurse must assess four interrelated ergonomic risk components:
+-----------------------------------------------------------------------------+
| THE TILE ERGONOMIC FRAMEWORK |
+---+-------------------+-----------------------------------------------------+
| T | TASK | Does the move involve twisting, stooping, bending, |
| | | excessive reaching, or long lifting distances? |
+---+-------------------+-----------------------------------------------------+
| I | INDIVIDUAL | Does the healthcare worker have adequate training, |
| | CAPABILITY | physical strength, pregnancy, or prior back injury? |
+---+-------------------+-----------------------------------------------------+
| L | LOAD | Patient weight, height, unpredictable movements, |
| | (PATIENT) | cognitive comprehension, pain, lines, and catheters?|
+---+-------------------+-----------------------------------------------------+
| E | ENVIRONMENT | Is there sufficient space around bed? Trip hazards, |
| | | slippery floors, bed height adjusted to hip level? |
+---+-------------------+-----------------------------------------------------+
Mechanical Handling Equipment
- Slide Sheets: Low-friction siliconized polyester sheets used in pairs or folded. Mandatory for in-bed repositioning, moving patients up the bed, and lateral transfers from bed to trolley. Never pull a patient directly across bedsheets without slide sheets.
- Active Standing Hoists (e.g., Sara Stedy, Sara 3000): Used for transfers (bed to chair, commode) in patients who are cognitively cooperative and can bear weight on at least one leg and maintain sitting balance.
- Passive Mechanical Hoists (Ceiling or Mobile Floor Hoists): Used for fully dependent, non-weight-bearing, or bariatric patients. Requires two trained operators and correct sling selection:
- Universal sling: Full body support with head extension.
- Hammock sling: For amputee patients.
- Toileting sling: For sanitary access (requires good head control).
- Transfer Boards (Banana Boards): Used for independent or assisted seated lateral sliding between bed and wheelchair.
Safe Body Mechanics Principles
- Base of Support: Maintain a wide, stable base with feet shoulder-width apart, one foot slightly forward in the direction of movement.
- Centre of Gravity: Bend at the hips and knees; keep your back straight; never bend at the waist.
- Load Proximity: Hold loads and patient handling handles close to your body.
- Eliminate Spinal Twisting: Turn by shifting your feet; never rotate or twist your spine while bearing weight.
- Bed Height Adjustment: Always raise the electric profiling bed to the knuckle or hip level of the shortest nurse prior to handling.
Clinical Traps & OSCE Safety Pearls
- OSCE Trap 1: Hoisting a Fallen Patient Without Primary Survey. Rushing to hoist a fallen patient back into bed before completing an ABCDE survey, cervical spine assessment, and checking for limb fractures is a critical safety failure.
- OSCE Trap 2: Performing a Manual Floor Lift. Attempting to manually lift a patient from the floor under their axillae (armpits) causes severe brachial plexus nerve injury and nurse lumbar injury. Always use a scoop stretcher, HoverJack, or floor hoist.
- OSCE Trap 3: Raising Bed Rails for Confused, Mobile Patients. In an OSCE station featuring a restless, confused patient trying to get out of bed, reflexively raising all four bed rails is graded as an inappropriate physical restraint. State that you will lower the bed, place a floor crash mat, and commence comfort rounds.
- OSCE Trap 4: Moving Patients in Bed at Low Working Height. Failing to raise the electric bed to working knuckle height before using slide sheets demonstrates poor ergonomic practice and results in point deductions.
A nurse hears a loud thud from a side room and discovers an 82-year-old male post-operative patient lying supine on the floor beside his bed. The patient is conscious, groaning, rubbing the back of his occiput, and complaining of severe right groin pain. What is the nurse's immediate priority management action?
An 80-year-old woman with moderate Alzheimer's dementia is admitted with acute delirium secondary to a urinary tract infection. She is disoriented to time and place, highly restless, and repeatedly attempts to climb out of bed to find her children. The night nurse suggests raising both full-length bed rails to prevent her from falling. How should this proposed intervention be evaluated under NMBI and Irish National Restraint Policy?
Two registered nurses are preparing to reposition a 115 kg dependent patient up in bed following major open abdominal surgery. Applying the TILE framework and Irish occupational health regulations (Safety, Health and Welfare at Work Act 2005), which clinical manual handling technique is mandatory?
