Ensuring the safety of elderly residents is a primary concern for care home operators across the globe. In the United Kingdom, falls represent one of the most significant risks to resident well-being, often leading to severe injuries, prolonged hospital stays, and a decline in overall quality of life. However, recent research conducted by Lancaster University demonstrates that integrating advanced technology into residential care environments can yield substantial, measurable improvements in resident safety. By utilizing AI-powered smart lights, care homes in the Lancashire and South Cumbria region successfully reduced falls by roughly a third, establishing a new benchmark for fall prevention in UK care homes.
The Growing Challenge of Falls in Residential Facilities
Falls among the elderly are a complex, multifaceted issue that carry heavy physical, emotional, and financial consequences. In residential settings, residents frequently present with varying degrees of frailty, advanced dementia, and high levels of clinical complexity. These factors inherently elevate the risk of falls. In many regions, including Lancashire and South Cumbria, care homes consistently experience fall rates exceeding 22 percent per 100 beds over a standard six-month period.
When a fall occurs, the immediate danger is compounded by what healthcare professionals refer to as a “long lie”—a prolonged period spent on the floor after a fall before receiving assistance. Long lies can lead to dehydration, hypothermia, pressure sores, and severe psychological distress. Furthermore, falls are a leading driver of emergency admissions, placing immense strain on local ambulance services and acute hospital trusts. For care home managers and staff, preventing these incidents requires constant vigilance, which can be exceptionally difficult amid ongoing staffing pressures and the need to provide individualized care for dozens of residents simultaneously.

Understanding the Technology Behind AI Smart Lights
To address the persistent challenge of unwitnessed falls and delayed response times, NHS Lancashire and South Cumbria Integrated Care Board (ICB) funded the deployment of approximately 800 AI-powered Nobi smart lights across 79 residential and nursing homes. The selected facilities were prioritized based on their high-risk profiles, ensuring that the technology was deployed where it could provide the maximum benefit.
Unlike traditional motion sensors or pull-cord alarms, which are often reactive and require resident intervention, these smart lights function proactively and unobtrusively. Installed directly in residents’ bedrooms, the devices are designed to look like standard ceiling lamps, preserving the homely aesthetic of the care environment. However, beneath the surface, they utilize artificial intelligence to monitor behavior and movement continuously, 24 hours a day, seven days a week.
When the system’s algorithms detect a fall, the lamp initiates a structured response protocol. First, it speaks directly to the resident, asking if they are okay. If the resident responds that they do not need help, the alert is cancelled. If there is no response, or if the resident explicitly asks for assistance, the smart light immediately dispatches a message to the care team’s mobile devices. Crucially, it also transmits a corresponding image showing exactly where and how the fall occurred. This visual context allows staff to assess the severity of the situation before entering the room and prepare the appropriate equipment or assistance.
Key Findings from the Lancashire and South Cumbria Trial
Researchers from the Lancaster University Centre for Ageing Research were commissioned by the ICB to conduct an independent, rigorous evaluation of the two-year initiative. As the largest evaluation of its kind in a care setting, the study combined quantitative data on fall rates and ambulance callouts with qualitative insights from care staff, providing a comprehensive view of the technology’s real-world impact.
Reduction in Fall Rates and Emergency Admissions
The most striking finding was a 32 percent reduction in the overall number of falls across the participating care homes. This statistic alone represents a massive improvement in resident safety. Additionally, the data revealed a 23 percent reduction in total ambulance callouts and a 24 percent reduction in callouts that resulted in hospital conveyance. By reducing the need for emergency transports, the care homes not only protected residents from the trauma and risks associated with hospital transfers but also alleviated significant pressure on regional emergency services.

Improving Staff Response Times
Perhaps the most operationally significant finding related to staff response times. Before the implementation of the smart lights, the average response time to a fall occurrence was approximately 11 minutes. After the technology was installed and operational, this average dropped to just 2.99 minutes. Drastically reducing this window is critical for preventing the complications associated with long lies and ensures that residents receive prompt medical evaluation and assistance following an incident.
Financial and Operational Benefits for Care Facilities
Beyond the clear health and safety advantages, the utilization of smart lights presents a compelling financial case for care home operators. The Lancaster University evaluation highlighted that the technology generates substantial cost savings by avoiding the expenses associated with hospital admissions, ambulance dispatches, and the extended care required after severe fall-related injuries.
According to the study, the use of Nobi lights in care homes is estimated to produce an average annual saving between £16,110 and £33,606 per individual home. When extrapolated across all the homes involved in the Lancashire and South Cumbria trial, the projected annual savings range from £918,306 to £1,915,549. For an industry that frequently operates on tight margins, these savings can be redirected toward improving facility amenities, increasing staff retention through better compensation, or investing in further care enhancements.
Furthermore, the qualitative data gathered by Lancaster University researchers indicated that over half of the care home managers felt the technology contributed to an overall improvement in residents’ well-being. By minimizing the physical trauma of falls and the anxiety of waiting for help, residents can experience a more stable, comfortable, and dignified quality of life.
Implementing Smart Light Technology in Your Facility
The success of the Lancashire and South Cumbria trial provides a clear roadmap for other care homes looking to adopt similar technologies. A critical factor in the success of this initiative was the high level of staff acceptance. The evaluation found that 80 percent of care home staff felt confident in using the technology. This high adoption rate was likely due to the unobtrusive nature of the lights and the tangible ways in which the technology assisted rather than hindered their daily workflows.
For facilities considering implementation, the process should begin with a thorough risk assessment to identify which rooms or residents are at the highest risk of unwitnessed falls. Engaging staff early in the planning process is also essential to address any concerns regarding privacy or workflow disruption. It is important to clarify to both staff and residents’ families that the smart lights are designed with privacy in mind—they only capture and transmit images when a fall is detected, functioning purely as a safety mechanism rather than a surveillance tool.

Once installed, management must ensure that protocols for responding to alerts are standardized and that staff are trained on how to interpret the data provided by the images. As noted by medical directors involved in the trial, the information regarding exactly how a fall occurred allowed staff to make proactive, environmental changes—such as adjusting furniture placement, improving lighting in specific room zones, or modifying care routines—to prevent future, similar incidents.
The Future of Technology-Driven Elderly Care
The independent evaluation by Lancaster University provides robust, credible evidence that AI-enabled care technology is not merely a futuristic concept, but a practical, highly effective tool currently available to the sector. As the demographic shift toward an aging population continues globally, the strain on traditional care models will only intensify. Relying solely on increased staffing to mitigate risks like falls is financially and logistically unsustainable.
Smart lights represent a specific application of a broader movement toward ambient intelligence in healthcare—environments that are sensitive and responsive to the presence of people. By seamlessly integrating safety monitoring into the physical infrastructure of a room, care homes can provide continuous protection without compromising the personal dignity or comfort of their residents.
The results from Lancashire and South Cumbria serve as a compelling case study for healthcare commissioners, care home operators, and regulatory bodies. When implemented thoughtfully, with an emphasis on staff training and data-driven care adjustments, smart light technology significantly improves fall prevention outcomes, generates substantial financial savings, and most importantly, keeps vulnerable residents safe.
