Measuring Quality of Life: How Environmental Design Impacts KPIs
Environmental design improvements are sometimes dismissed as 'soft' interventions that are difficult to measure. In reality, the impact of signage and design on quality of life can be tracked through existing care home KPIs -- from falls data and medication use to inspection ratings and family satisfaction scores.
Care home managers and operators face constant pressure to demonstrate quality improvement. Regulatory bodies demand evidence of good outcomes, commissioners require quality metrics, and families expect transparency about the standard of care their loved one receives. Environmental design is sometimes perceived as a 'nice to have' rather than a measurable intervention, but this perception is outdated. A growing body of evidence, led by the DSDC at the University of Stirling and supported by research from the Bradford Dementia Group and Alzheimer's Society, demonstrates that environmental modifications -- including signage, lighting, and spatial design -- produce measurable improvements across multiple quality of life indicators.
Falls and Safety Metrics#
Falls are one of the most closely monitored metrics in care homes, and one where environmental design has a direct and measurable impact. Research published in Age and Ageing found that improved wayfinding signage reduced corridor falls by up to 30% in dementia care settings. Night-time falls, often caused by residents searching for the toilet in inadequate lighting, are reduced by high-contrast toilet signs and low-level corridor lighting. Every fall prevented is a measurable outcome that translates into reduced injury, reduced hospital admissions, and improved regulatory metrics.
Quality of life KPIs affected by environmental design:
- Falls frequency and severity -- particularly corridor and toilet-related falls
- Use of PRN (as needed) anxiolytic and antipsychotic medication -- reduced when environmental anxiety triggers are addressed
- Incontinence episodes attributable to wayfinding failure rather than physiological cause
- Weight and nutritional status -- improved when residents can find and navigate the dining room independently
- Engagement scores from Dementia Care Mapping or similar tools -- improved when residents access communal spaces
- Challenging behaviour incident frequency -- reduced when environmental triggers are eliminated
- Family satisfaction survey scores -- improved when the environment visibly supports their loved one
- Staff sickness and turnover rates -- reduced in calmer, better-designed environments
- Regulatory inspection ratings -- improved when environmental quality is evident to inspectors
Medication Reduction as a Quality Indicator#
NICE guidelines recommend non-pharmacological approaches as the first-line management of behavioural symptoms in dementia, yet many care homes still rely heavily on medication. Antipsychotic prescribing in dementia care is a specific focus for the CQC and other regulators. Environmental design that reduces agitation and anxiety addresses the root causes of much of this prescribing. Care homes that implement comprehensive signage and wayfinding improvements consistently report reductions in PRN medication use, providing a measurable quality indicator that aligns with national prescribing guidelines and impresses regulators.
Pro Tip
Before implementing a signage improvement, record your baseline metrics: falls rate, PRN medication use, engagement scores, and incident frequency. After implementation, measure the same metrics at 3, 6, and 12 months. This data demonstrates ROI to directors and commissioners and provides evidence for inspection.
Building a Business Case for Design Investment#
A complete signage system for a 40-bed care home typically costs less than the equivalent of two weeks' agency staff cover. Yet the return on this investment is measurable across multiple KPIs and sustained over years. Fewer falls mean fewer hospital transfers and fewer serious injury investigations. Reduced medication use aligns with regulatory expectations and reduces pharmacy costs. Higher engagement scores demonstrate quality of life improvements to commissioners. Better inspection ratings protect occupancy and revenue. For care home operators, environmental design is one of the highest-ROI investments available.
The King's Fund's research on care home environments concludes that the physical environment is 'the silent partner in care delivery.' Measuring its impact through existing KPIs transforms it from a background feature into a strategic quality improvement tool.

"After installing a complete signage system, our falls reduced by 28%, PRN anxiolytic use dropped by 35%, and our next CQC inspection moved us from 'Requires Improvement' to 'Good' on the safe domain. The signage paid for itself within the first quarter." -- Operations Director, Care Home Group, South East England
Measuring quality of life is not about reducing human experience to numbers. It is about ensuring that the care environment is genuinely delivering the outcomes it promises. When environmental design improvements produce measurable benefits across falls, medication, engagement, satisfaction, and regulatory compliance, they validate the investment and, more importantly, confirm that residents are living better because of the changes made. That is the ultimate quality metric.
