"You can't improve what you don't measure."
— Lord Kelvin

Lord Kelvin was a physicist, engineer and mathematician who became known for his work in measurement and scientific thinking. Whilst he certainly wasn't talking about care services when he made this observation, I often think the quote is just as relevant to health and social care today as it was to science over a hundred years ago.

Throughout my career, I have worked with services that were performing well and services that were facing significant challenges. What has always interested me is that most leaders genuinely want to improve. I rarely meet a Registered Manager, Provider or Quality Lead who comes to work thinking, "How can I stand still today?"

Most people are working incredibly hard. Action plans are written, audits are completed, staff meetings take place, incidents are reviewed and training is delivered. Yet despite all of this activity, there are times when services still struggle to answer a very simple question:

Are we actually improving?

That question can sometimes feel uncomfortable because activity is often much easier to demonstrate than impact.

I remember working with a service some years ago that had a very impressive audit schedule. Everything was being audited. There were folders full of reports, action plans and monitoring records. On the surface, it looked like a service with strong governance arrangements.

However, when we started looking more closely, a different picture emerged.

The audits were being completed, but recurring issues continued to appear month after month. The same concerns were being identified, the same actions were being agreed and yet little seemed to be changing.

The issue wasn't that the service wasn't measuring anything. The issue was that nobody had stopped to ask what the information was actually telling them.

That experience has stayed with me because it highlights something I see regularly across the sector. We can become very focused on collecting information without always taking the time to understand it.

Take nutrition as an example. Most services will routinely monitor weights and complete MUST assessments. Those are important measures and provide valuable information. However, simply recording a person's weight each month does not improve nutritional outcomes.

The value comes from understanding what those measurements are telling us. Has somebody's weight been gradually declining over the last three months? Are nutritional interventions having the desired effect? Have referrals been made at the right time? Are we seeing improvement, deterioration or no change at all?

The measurement itself is only the starting point. What matters is how we interpret the information and what actions we take as a result.

The same principle applies to almost every aspect of service delivery.

A single complaint may tell us about one person's experience. A series of complaints over six months may tell us something about communication, staffing or culture.

A single medication error may be an isolated incident. A pattern of medication errors may indicate a training need, a process issue or wider concerns that require attention.

A safeguarding concern may be significant in its own right. Several safeguarding concerns linked by a common theme may reveal risks that would never be identified if each concern was viewed in isolation.

This is where leadership becomes so important.

Strong Registered Managers don't simply collect information because they are expected to. They remain curious and look beyond the numbers and ask questions. What is this information telling me?, what patterns are emerging?, what has changed over time? and evidence do I have that the actions we have taken are making a difference?

I often encourage leaders to think about the difference between measuring activity and measuring outcomes.

For example, a service may be able to demonstrate that every member of staff has completed their mandatory training. Whilst that is useful information and provides assurance that training requirements are being met, it is only part of the picture.

The more important question is what difference that training has actually made.

Has it improved practice? Has it increased staff confidence and competence? Has it reduced incidents, improved decision-making or led to better outcomes for the people using the service?

The same principle applies across many aspects of service delivery. Audits may be completed, supervision sessions may take place, observations may be carried out and action plans may be implemented, but the real value lies not in the completion of these activities. The real value lies in understanding what they have achieved.

Have they improved quality? Have they reduced risk? Have they strengthened governance? Have they enhanced the experience of people using the service?

Completing the activity is important, but effective leaders look beyond completion rates and compliance. They focus on understanding the impact of their actions and whether those actions are contributing to meaningful and sustainable improvement.

Reflection

As you reflect on your own service this week, it may be worth considering where your most valuable information comes from.

What information gives you the clearest understanding of the quality of care people are receiving and what measures genuinely help you understand how your service is performing?

Perhaps most importantly, are you collecting information simply because it has always been collected, or are you using it to drive meaningful improvement?, because Lord Kelvin's observation remains as relevant today as ever.

If we want to improve something, we first need to understand it and if we want to understand it, we need to measure the things that matter most.
