v
A
[Angela]:
Welcome to Cost Saver Conversations. I'm Angela, and I ask the practical questions so you can quickly understand what matters. Today, I'm joined by Asad.
A
[Asad]:
Hi Angela. We are unpacking "Why NHS Prescription Spending by ICB Varies Across England and How to Read the Data Fairly" today and tying it back to the wider Cost Saver ecosystem, including tools like NHS ICB Prescribing Explorer, so you can turn insights into action quickly.
A
[Angela]:
Just a heads-up before we dive in: we are your synthetic hosts. We are great with numbers, but as AI, we can sometimes be confidently wrong. Think of us as the digital versions of your most knowledgeable, slightly caffeinated friends.
A
[Asad]:
Exactly. Treat this chat as a smart estimate only, not as professional financial guidance. Always check important details with official sources or a qualified expert before making any big decisions.
A
[Angela]:
Hello and welcome back to Cost Saver. I'm Angela, and joining me as always is Asad. So — today we're getting into something that sounds, on the surface, kind of... dry. NHS prescription spending data. But Asad, I have a feeling this is one of those topics where the more you dig, the more interesting it gets.
A
[Asad]:
Yeah, it really is. And honestly, it's one of those areas where a misread figure can cause genuine harm — not just confusion, but actual poor decisions at a local level. So, um, it's worth taking seriously.
A
[Angela]:
Right. So let's set the scene. We're talking about NHS prescription spending by ICB — Integrated Care Boards. And the premise is, you open a spreadsheet, you see one area spending way more than its neighbour, and your first thought is... someone's wasting money.
A
[Asad]:
Exactly. And it's a completely natural reaction. I'd probably think the same thing, honestly. But it's — well, it's usually the wrong one. That's sort of the whole point of this.
A
[Angela]:
Okay. So before we even get to why spending differs — can you just explain what we're actually looking at when we see this data? Because I think a lot of people assume it's fairly straightforward.
A
[Asad]:
Yeah, so — most of the public prescribing data comes from the NHS Business Services Authority, the NHSBSA. And what they're counting, broadly, is prescriptions written in England and dispensed in the community. So your local pharmacy, appliance contractors, that kind of thing. Some hospital-written prescriptions that get dispensed in the community are in there too.
A
[Angela]:
Okay, that sounds fairly clear so far.
A
[Asad]:
It does, but — here's where it gets a bit tricky. The main unit you'll see is a prescription item. And a prescription item is, um, it's one entry for one medicine on a prescription form. So if a doctor prescribes three different medicines on one form, that's three items. If the same patient collects the same medicine every month for a year, that's twelve items.
A
[Angela]:
Oh! So an item count isn't a count of patients at all.
A
[Asad]:
Not at all, no. And this is where people really trip up. Two areas could have the same number of items but very different numbers of actual patients — just because one tends to issue shorter prescriptions, say monthly, and another issues longer ones, three months at a time.
A
[Angela]:
Hm. So you can't use it to say, oh, this area is prescribing to more people.
A
[Asad]:
Not reliably, no. You can't tell from an item count how many different people got medicines, how long each prescription lasted, whether the medicine was even taken correctly — none of that. It's a very specific measure that answers a very specific question, and it gets misused a lot.
A
[Angela]:
Which is kind of... a lot to get wrong before you've even started comparing anything.
A
[Asad]:
[laughs] Yeah, exactly. And then there's the cost side, which has its own complications on top of that.
A
[Angela]:
Go on.
A
[Asad]:
So the NHSBSA publishes more than one cost measure. The two main ones are net ingredient cost and actual cost. Net ingredient cost is basically the basic price of the medicine before discounts and fees. Actual cost tries to reflect what the NHS actually pays after discounts, with dispensing fees added in.
A
[Angela]:
So they're — they're not the same thing.
A
[Asad]:
They're not, no. Neither is wrong — they just answer different questions. But if you compare one area's net ingredient cost with another area's actual cost, you're comparing apples with pears. And that happens more than you'd think.
A
[Angela]:
That's a really easy mistake to make, actually. Especially if you're just, you know, downloading a spreadsheet and getting stuck in without — without really checking what column you're looking at.
A
[Asad]:
Totally. So the most useful trio of numbers, if you want a sensible picture, is — total items prescribed, total cost, and average cost per item. Those three together tell you so much more than any one of them alone. Does that make sense?
A
[Angela]:
Yeah, it does. Because — okay, so an area could have a high total cost but a low cost per item, which means it's just... volume. Lots of people, lots of medicines.
A
[Asad]:
Exactly right. Or the other way — average volume but a really high cost per item, which points to a handful of very expensive medicines. And those are completely different stories.
A
[Angela]:
So we should never be treating a ranking of ICBs by total spend as a league table of efficiency.
A
[Asad]:
Never. I mean — total spend mostly reflects how many people live in an area and how much medicine they actually need. It's not a measure of how well the money's being managed.
A
[Angela]:
Right. Okay. So — let's get into the why. Why does spending vary so much across England's 42 ICBs?
A
[Asad]:
So the — the reasons usually overlap, but there are a few main ones. The simplest is just... people. A bigger population needs more medicines in total. So raw totals will always flatter small ICBs and penalise large ones. That's why any fair comparison really needs a per-person figure rather than a raw total.
A
[Angela]:
And age comes into it as well, I'd imagine.
A
[Asad]:
Massively, yeah. Older people are more likely to be living with several long-term conditions, and those conditions often need regular medication. So an ICB that covers, say, a coastal town with a lot of older residents is going to show more items and higher costs than one covering a city with a younger, more mobile population — even if the clinicians in both places are prescribing really carefully.
A
[Angela]:
Which is kind of obvious when you say it out loud, but I don't think people always make that connection when they're staring at the numbers.
A
[Asad]:
They really don't. And analysts do adjust for this — there's age and sex weighting, using prescribing units that reflect the make-up of a practice list. You don't need to do the maths yourself, but it helps to know that a simple per-head figure is only a first step. It's not the whole story.
A
[Angela]:
What about deprivation? Because I feel like that must play a role too.
A
[Asad]:
It plays a huge role. Health isn't spread evenly across England — conditions like diabetes, heart disease, asthma, COPD, mental illness — they're more common in some communities than others. And deprived areas often have higher rates of illness and more people living with several conditions at once.
A
[Angela]:
So more prescribing, higher spending.
A
[Asad]:
Right. And — and this is the important bit — that's often the system working as intended. Someone with diabetes and high blood pressure will reasonably be on several regular medicines. A higher bill in those places can reflect real need, not overuse.
A
[Angela]:
So lower prescribing isn't automatically better.
A
[Asad]:
No, it really isn't. Lower prescribing can also point to under-treatment or missed diagnoses. Which is — I mean, that's potentially a much bigger problem than spending a bit more.
A
[Angela]:
Hmm. I hadn't thought about it like that, actually. That's — yeah, that reframes it quite a bit.
A
[Asad]:
Yeah. And then there's the mix of medicines, which is where totals can really mislead. Not all medicines cost the same — that's obvious — but a small number of high-cost medicines can account for a large share of spending, even when the item count looks completely ordinary.
A
[Angela]:
So two areas could look identical on volume but be really different on cost.
A
[Asad]:
Exactly. And that cost-per-item figure helps you spot that pattern quickly. You also want to ask whether a cost rise is coming from — uh, a change in the price of a common medicine, or a new treatment being used more widely, or more patients getting an existing medicine, or a shift from one product to another. Each of those has a different meaning.
