The night shift problem
Night time is when care homes face a stark mismatch: the highest risk of falls with the fewest staff to respond.
Research published in the British Medical Journal and supported by NHS England data consistently shows that falls are approximately three times more likely during the night than during daytime hours for care home residents. The reasons are straightforward: residents get up to use the toilet in the dark, they are groggy and disoriented, medication side effects peak during the night, and the postural hypotension that causes dizziness is worst when rising from a lying position.
Yet staffing levels at night are typically a fraction of daytime levels. A care home with 15 staff during the day might have 2-3 at night. In domiciliary care, there are usually zero staff present between the evening and morning visits.
The result is predictable: falls happen at night, detection is delayed, and outcomes are worse. NHS data shows that night-time falls in care settings result in longer hospital stays and higher mortality rates than daytime falls. Not because the falls are more severe, but because they are discovered later.
Where falls happen at night
Understanding where night-time falls happen matters because it determines which monitoring solutions can actually help.
| Location | Approximate % of night falls | Common cause |
|---|---|---|
| Bedroom (beside the bed) | 40-50% | Getting out of bed, tangled in bedding, reaching for items |
| En-suite bathroom | 20-30% | Wet floor, toilet transfer, dizziness on standing |
| Corridor (en route to bathroom) | 15-20% | Disorientation, poor lighting, rushing |
| Other (communal areas) | 5-10% | Wandering, confusion, seeking help |
The important point here: 60-80% of night-time falls happen in bedrooms and bathrooms, the two locations where cameras cannot legally or ethically be installed. Any monitoring solution that relies on cameras is blind in the rooms where it is needed most.
Current night monitoring: what is not working
Hourly rounds
The most common approach in residential settings is scheduled rounds: a night staff member walks through the building, opening doors and visually checking each resident at set intervals, typically every one to two hours.
The problems with rounds are numerous:
- They disturb sleep. Opening a door, shining a torch, and checking on a resident inevitably causes sleep disruption. Research from the University of Stirling found that scheduled night rounds are one of the leading causes of sleep disturbance in care homes, and poor sleep is itself a risk factor for falls the following day.
- They miss events between checks. A resident who falls at 1:05am and is not checked until 2:00am lies on the floor for 55 minutes. If the round is every two hours, it could be nearly two hours.
- They are hard to do well with 2-3 staff. In a 40-bed home with 2 night staff, a thorough round takes 30-45 minutes. By the time you finish, it is nearly time to start again, leaving no capacity for actual care tasks, medication, or responding to call bells.
- Documentation is unreliable. Studies have found that night round documentation is often completed retrospectively or inaccurately, which undermines its value as evidence of care quality.
Bed sensors and pressure mats
Some care homes use bed occupancy sensors or pressure mats beside the bed. These detect when a resident leaves the bed, triggering an alert.
The limitation is that they only detect bed exit, not what happens afterwards. The resident may get up, use the bathroom, and return to bed safely. Or they may fall in the bathroom. The sensor cannot tell the difference, leading to either excessive false alarms (alert on every bed exit) or under-response (staff learn to ignore frequent alerts).
Night cameras
Some providers have explored cameras in communal areas for night monitoring. Setting aside the ethical concerns, cameras are legally prohibited in bedrooms and bathrooms under UK privacy law and GDPR principles. Since 60-80% of night falls happen in these rooms, cameras cannot solve the night-time monitoring problem.
The waking night dilemma
Care homes face a stark staffing choice at night:
- Waking night staff: fully awake and available all night. Effective but expensive. A waking night carer costs £25,000-£35,000 per year in salary alone, before on-costs. For adequate coverage, you may need 2-4 waking night staff depending on the size of the home.
- Sleep-in staff: present on site but sleeping unless needed. Much cheaper, but they must be woken by an alert to respond. If there is no alert system that detects falls, they only wake for call bells that the fallen resident may not be able to reach.
Neither option is satisfactory. Waking night cover is unaffordable for many providers. Sleep-in cover without automatic fall detection leaves dangerous gaps.
Passive radar monitoring: a different approach
60GHz radar sensors mounted on the wall detect human presence, movement, and falls continuously, including in bedrooms and bathrooms, day and night. Because the technology uses radio waves rather than cameras, it raises no privacy concerns and is legal in every room.
How it works at night
The sensor operates silently and invisibly. It emits no light, makes no sound, and requires nothing from the resident. During the night:
- It tracks whether the resident is in bed, out of bed, or moving around the room
- If a fall is detected (a rapid transition from standing to floor level followed by immobility) an automatic alert is sent to night staff
- If prolonged inactivity is detected outside normal sleep patterns (e.g., the resident is on the bathroom floor for more than a set threshold), an alert fires
- The resident is never disturbed. There is no light, no sound, no physical interaction with the technology
What it changes for night staff
The shift from rounds to radar changes how night care operates:
| Rounds-based model | Alert-based model |
|---|---|
| Check every room every 1-2 hours | Respond only when an alert indicates a problem |
| Disturbs sleeping residents | No disturbance, residents sleep undisturbed |
| Gaps of up to 2 hours between checks | Continuous monitoring with instant alerts |
| Cannot monitor bathrooms | Monitors all rooms including bathrooms |
| Staff spend most of the night walking corridors | Staff available for care tasks, medication, and targeted response |
| Documentation based on visual check (often unreliable) | Automatic logging of movement and events |
This does not mean night staff are no longer needed. They absolutely are, for medication, personal care, comfort, and emergency response. But instead of spending their shift walking corridors and opening doors, they can focus on the residents who actually need attention, guided by data rather than routine.
Implementation in care home settings
Deploying radar monitoring for night-time coverage involves practical considerations specific to residential settings.
Sensor placement
For night-time fall coverage, the priority locations are:
- Bedrooms: wall-mounted opposite or adjacent to the bed, positioned to cover the bed exit area and the path to the door
- En-suite bathrooms: covering the toilet area and the transition from standing to sitting
- Corridors: optional but useful for tracking night-time wandering
With a hardware cost of approximately €90 per sensor kit at B2B pricing, equipping a 30-bed home's bedrooms costs significantly less than one year of an additional waking night staff member's salary.
Alert routing for night shifts
Night alerts should route to:
- The on-duty night team (via mobile app, pager, or facility alert system)
- The night manager or on-call manager as escalation
- Optionally, a log for the morning handover team
Integration with night routines
Monitoring data can enhance rather than replace your night care routines:
- Use activity data to identify which residents are actually awake and might benefit from a check or comfort measure
- Reduce routine rounds for residents who are sleeping soundly, directing staff time to those who are restless or at higher risk
- Use night activity reports in morning handover briefings to flag residents who had disturbed nights
The impact on sleep quality
One of the less obvious benefits of alert-based night monitoring is improved sleep for residents. Research consistently links sleep quality in care homes to:
- Reduced fall risk the following day
- Better cognitive function
- Lower agitation and anxiety
- Reduced need for sedative medication
When you stop opening doors every hour to check on sleeping residents, sleep quality improves. When sleep improves, fall risk decreases. No amount of additional staffing can create this effect if the staffing model itself is the source of disruption.
Making the case for night monitoring
If you are considering radar-based night monitoring for your care home, the argument comes down to three things:
- Safety: continuous coverage eliminates the 1-2 hour gaps in rounds-based monitoring. Falls in bedrooms and bathrooms (the majority of night falls) are detected immediately rather than at the next scheduled check.
- Quality: better sleep for residents, more targeted care from night staff, data for morning handovers, and CQC evidence of night-time risk management.
- Cost: the hardware investment for a full care home is a fraction of the cost of an additional waking night staff member, and it provides more comprehensive coverage than any staffing model can achieve.
