Why Elderly People Face Greater Risk
Adults aged 65 and older consistently make up a disproportionate share of disaster fatalities. During Hurricane Katrina, roughly 70% of those who died were over 60. In the 2003 European heat wave, an estimated 35,000 excess deaths occurred — the elderly representing the vast majority. This vulnerability is not inevitable. With deliberate planning, older adults can weather emergencies with far greater safety.
Several intersecting factors create this elevated risk: reduced physical mobility, greater dependence on medications and medical equipment, diminished ability to regulate body temperature, cognitive conditions such as dementia, social isolation, and limited access to real-time information. Each factor can be addressed.
Mobility Challenges and Evacuation
Understanding the Range of Mobility
Not all older adults have limited mobility, but planners must account for the full spectrum:
| Mobility Level | Description | Evacuation Implication |
|---|
| Fully independent | Walks unassisted, drives | Standard evacuation planning |
| Cane or walker dependent | Slower pace, requires assistance on stairs | Allow extra time, avoid crowds |
| Wheelchair user (manual) | Needs clear paths, assistance over obstacles | Requires helper, accessible transport |
| Wheelchair user (power) | Heavy chair, battery-dependent | Requires vehicle with ramp, charged battery |
| Bed-bound or hoist-dependent | Cannot self-evacuate | Requires multiple helpers, ambulance transport |
Evacuation Planning Steps
- Assess the older adult's specific mobility level honestly — many people overestimate their capacity in a calm setting versus an emergency.
- Identify accessible evacuation routes. Multi-storey homes require a ground-floor evacuation plan or a pre-arranged "area of refuge" if evacuation is impossible.
- Arrange transport in advance. Standard emergency shelters may have limited wheelchair-accessible vehicles. Contact your local council or emergency management office at least annually to register for accessible transport.
- Practice the evacuation. Walk the route with the older adult at a realistic pace. Time it. Identify obstacles — steps, gravel paths, narrow doorways.
- Identify two trained helpers beyond immediate family — neighbours, faith community members, or paid carers who know the plan.
- Keep a "go bag" already packed near the front door, at a height the person can reach.
Medications: The 90-Day Supply Rule
Medication interruption is one of the most dangerous and most preventable risks for older adults in emergencies.
⚠️ Many emergencies last far longer than people expect. A 72-hour supply is insufficient. Aim for a 90-day supply of all critical medications, rotated to prevent expiry.
Building a Medication Reserve
- Speak with the prescribing doctor or pharmacist about obtaining a larger supply. In many countries, insurance will permit a 90-day dispensing for long-term medications.
- Use a rotating system: use from the front, add new stock to the back.
- Store medications in a cool, dry location away from direct sunlight. For temperature-sensitive medications (such as some insulins), know the alternative storage plan when refrigeration is unavailable.
- Keep a printed medication list in the go bag. Include: medication name, dose, frequency, prescribing doctor, and pharmacy contact. Update it every time medications change.
- Photograph the medication list and store it in cloud-accessible phone storage so a carer can access it remotely.
Medication List Template
| Medication Name | Dose | Frequency | Condition It Treats | Prescriber | Dispensing Pharmacy |
|---|
| Example: Metoprolol | 50 mg | Once daily (morning) | Hypertension | Dr Smith | City Pharmacy |
| Example: Warfarin | 3 mg | Once daily (evening) | Atrial fibrillation | Dr Ahmed | City Pharmacy |
Life-Sustaining Medical Equipment
Older adults who rely on powered medical equipment face a specific set of risks during power outages or evacuations.
Oxygen Concentrators
- Concentrators require continuous electrical power. Without it, a patient may have only hours of supplemental oxygen remaining from portable cylinders.
- Register with your electricity provider as a life-support customer. Many providers offer priority reconnection and advance warning of planned outages.
- Maintain at least a 48-hour portable oxygen cylinder backup, and know how to switch from concentrator to cylinder.
- Carry the oxygen prescription documentation in the go bag — airlines, emergency shelters, and hospitals need this.
Dialysis
- Home dialysis patients should contact their dialysis centre's emergency planning coordinator. Most centres have pre-established agreements with facilities in evacuation zones.
- Know the nearest dialysis centre in your planned evacuation destination.
- Carry sufficient supplies for at least two extra sessions in case of transport delay.
- Medic Alert identification documenting dialysis dependence is essential.
Pacemakers and Implantable Defibrillators
- These devices are battery-powered internally and do not require external electricity, but the person wearing them may still need follow-up care if they miss scheduled checks.
- Carry the device identity card (issued by the manufacturer) at all times. This card contains model information needed by emergency medical staff.
- Note that some airport security scanners and strong electromagnetic fields can interfere with some devices — relevant during evacuation.
Power Wheelchairs and Stair Lifts
- Keep power wheelchairs plugged in and at full charge whenever possible.
- Identify a manual wheelchair backup.
- If the household has a stair lift, rehearse ascending and descending stairs manually with assistance in case of power failure.
Vulnerability to Temperature Extremes
Heat
The body's ability to regulate temperature decreases with age. Sweat gland function diminishes, recognition of thirst declines, and several common medications (diuretics, beta-blockers, antihistamines, antipsychotics) impair thermoregulation further.
Signs of heat stress requiring immediate action: confusion, cessation of sweating despite heat, rapid pulse, loss of consciousness.
During a heat emergency:
- Move the person to the coolest available location — air-conditioned buildings, underground levels.
- Apply cool (not ice-cold) water to skin and fan it.
- Offer small sips of water if fully conscious.
- Do not leave alone.
Cold
Older adults experience core temperature drops faster than younger adults and may not shiver effectively — a warning sign that thermoregulation is already compromised. They may also not feel cold even when dangerously hypothermic.
During a heating failure:
- Layer clothing, focusing on the core and head.
- Use sleeping bags rated below current ambient temperature.
- Move to a community warming shelter at 15°C or below for vulnerable individuals.
- Check in on older neighbours who live alone every few hours.
Cognitive Impairment and Dementia
People with dementia present specific emergency planning challenges. Disruption of routine triggers acute distress; unfamiliar environments increase disorientation; self-care capacity may be overestimated by carers.
- Attach an ID wristband or sewn label with name, address, and emergency contact to frequently worn clothing.
- Prepare a brief laminated "communication card" explaining the condition to emergency responders.
- During evacuation, maintain as much routine as possible — same mealtimes, familiar objects in the go bag (a photo album, a favourite blanket).
- Tell emergency shelter staff immediately on arrival about the condition and level of supervision needed.
- Plan for behavioural responses to stress — agitation, wandering, refusal to leave — and have strategies prepared with carers.
Social Isolation and Community Networks
Social isolation is not merely a quality-of-life issue — it is a survival risk. Isolated older adults are far less likely to receive timely warning, assistance, or rescue.
- Map the immediate social network of every older adult you are responsible for. How often does someone see them face-to-face? Who holds a spare key?
- Establish a daily check-in system that activates during emergencies — a text, a call, a knock on the door.
- Know the older adult's neighbours and brief them on any special needs.
- Connect with neighbourhood emergency preparedness groups or local councils — many run formal "vulnerable persons registers."
Pre-Registering with Emergency Services
Many local authorities and utility companies maintain registers of vulnerable adults for use during emergencies. Registration can result in priority evacuation assistance, welfare checks, and priority utility restoration.
- Contact your local council's emergency planning team and ask about their vulnerable persons register.
- Contact your electricity, gas, and water providers and ask about priority service registers for medical and elderly customers.
- Provide written consent if registering on behalf of another adult.
- Update registrations annually or whenever the person's circumstances change.
⚠️ Registration is not a guarantee of rescue. It improves your odds of receiving assistance, but you must still maintain your own preparedness plan.
Caregiver Planning
Family members or paid carers who support older adults need their own emergency plan that accounts for their role.
- Identify a backup carer who can fulfil your role if you are incapacitated, at work, or unreachable during an emergency.
- Brief the backup carer fully on the older adult's medical conditions, medications, equipment, and personality.
- Leave a written care summary at the older adult's home.
- Discuss in advance what decisions the backup carer is authorised to make.
- Ensure the older adult's legal documents (advance care directive, power of attorney) are accessible and up to date.
Emergency Kit Checklist for Older Adults
Beyond the standard household emergency kit, older adults should ensure:
- 90-day medication supply, current and rotated
- Printed medication and medical history list
- Copies of health insurance cards and advance care directives
- Spare glasses and hearing aid batteries (minimum 2-week supply)
- Comfortable, non-slip footwear near the exit
- Portable phone charger (fully charged)
- Communication device appropriate to any sensory impairment
- Personalised comfort items for psychological grounding
