Drive the A39 south from Bude to Padstow and you cover roughly 45 miles of Cornish north coast — four market towns (Bude, Camelford, Wadebridge, Padstow), the dramatic Crackington Haven / Tintagel stretch, and a handful of scattered villages (Boscastle, Trebarwith, Delabole, St Kew). In winter the corridor is quiet, farming, fishing and fewer than 30,000 year-round residents. In summer it doubles or triples with holidaymakers.

PharmSee's /api/location/analyze endpoint lets us map the pharmacy provision along that 45-mile strip in enough detail to say, for the first time, exactly how many community pharmacies exist for how many GP practices — and where the closure-risk thin spots are.

The four anchor towns

Source: PharmSee /api/location/analyze on each anchor, 3-mile radius, 2026-04-11.

Widening the net to Bude's 15-mile catchment gives us the corridor-level picture: 8 pharmacies serving 5 GP practices across the full stretch, a corridor ratio of 0.62:1. The pharmacy supply is structurally ahead of the GP supply — a pattern familiar from other coastal corridors, where retired populations pull pharmacy provision up but the GP sector is thinned by workforce shortages.

The Padstow single-site phenomenon

Padstow is the corridor's most telling data point. A query against PL28 8AE returns:

• GP practices (3 miles): 0
• Pharmacies (3 miles): 1
• Chain: Boots
• Annual dispensing revenue (latest PharmSee data): £66,647
• Annual item volume: 51,665

The £66k revenue figure is approximately one-fifteenth of a typical Boots branch in the national PharmSee dataset. Boots' average community branch runs around £1m-£1.2m annually on NHS dispensing. Padstow's single Boots is running at roughly 5-6% of that national average.

Two explanations fit the data:

1. The Padstow catchment is genuinely that small in winter. The town's permanent population is around 3,500. Most Padstow residents in need of regular medicine collection actually register with a GP in Wadebridge — a six-mile drive — and collect their prescriptions there rather than at the Padstow Boots. The single Boots branch services walk-ins, holidaymakers, and the minority of Padstow residents who use the St Petroc Medical Centre satellite. The NHS Digital contract is structured to be cost-minimal in that catchment.

2. The dispensing data may be stale for Padstow specifically. Our data pipeline pulls NHSBSA FP10 dispensing records on a rolling basis and small branches can take longer to re-materialise. The £66k figure is directionally credible but should be treated as "very low" rather than "exactly £66,647".

Either way, Padstow's Boots is the closest thing the entire PharmSee 13,147-pharmacy register has to a borderline-viability branch from a pure dispensing revenue standpoint.

Bude's 0.25:1 ratio explained

Bude presents the opposite anomaly: four pharmacies around a single GP practice. Reading the ratio at face value ("Bude has four times the pharmacy supply of its GP coverage") is misleading. The three-mile radius around EX23 8LE catches:

• Belle Vue Pharmacy (at 0.18 miles from the anchor)
• Three other branches scattered between Stratton, Bude town centre, and Flexbury Avenue
• One GP practice — Stratton Medical Centre at EX23 9BP, 1.3 miles distant

The missing piece is that Bude's second large GP practice — Neetside Surgery — sits fractionally outside the 3-mile ring on the southern side of the town. The true Bude ratio, including Neetside, is closer to 0.5:1. Still comfortable, but not the extreme 0.25 the raw query returns.

Data integrity caveat: when mapping pharmacies against GP practices in rural coastal catchments, 3-mile radii can dramatically over- or under-count depending on which side of the ring the nearest surgery falls. For urban cities the 3-mile radius is self-correcting; for rural corridors it is not. This is a known PharmSee methodology limitation and one we'll document more fully in the next wiki data inventory update.

The closure-risk thin spots

Applying normal PharmSee closure-risk heuristics to the corridor:

High risk: Padstow (single branch, £66k revenue, 0 nearby GP support). If the branch closed tomorrow, the next nearest pharmacy is at Rock (across the Camel Estuary by ferry — a genuinely inconvenient journey) or a 6-mile drive to Wadebridge.

Medium risk: Camelford (three-surgery-area served by five pharmacies at the Launceston edge of the radius). The market town centre is small enough that even one mid-size closure materially hollows provision.

Low risk: Bude (four branches, strong walk-in holiday trade) and Wadebridge (balanced 2/2 ratio plus a large Boots at the Eddystone Road retail park).

What Pharmacy First means on this corridor

The seven clinical pathways of Pharmacy First are especially valuable in rural coastal catchments because they compress an unnecessary GP appointment — often a 10-15 mile drive — into a walk-in pharmacy consultation. But the scheme requires a qualified pharmacist available during opening hours, PharmOutcomes logging, and a GP-practice referral relationship.

For a single-site rural branch like Padstow Boots the Pharmacy First math is stark:

• Consultations/year potential: 100-150 (heavy cap on capture due to thin winter footfall and seasonal summer surge that doesn't always convert)
• Revenue potential: £1,500-£2,250
• Pharmacist-hours required: 30-40 hours per year of dedicated consultation time

In a normal Boots the £1,500-£2,250 is a rounding error against a £1m dispensing turnover. In a Padstow-sized branch it's almost 3% of total NHS revenue — the difference between the branch being viable and needing cross-subsidy from the chain.

What the corridor needs from NHS and ICB commissioners

1. Explicit single-branch protection for Padstow, Bude and comparable sites. The Pharmacy Access Scheme (PhAS) already supports some rural pharmacies — the corridor deserves a formal review of whether the Padstow Boots should be protected under PhAS top-up funding.

2. Seasonal staffing support. The summer population surge is a known pattern. A corridor-wide seasonal pharmacist rotation, funded by the ICB and shared across all 8 branches, would reduce locum costs and improve Pharmacy First capture.

3. Better integration with the GP-practice network. The 5 GP practices across the corridor (Stratton, Neetside, Camelford, Wadebridge, St Petroc) need formal Pharmacy First referral protocols. Absence of those protocols is the biggest single constraint on corridor-level consultation volume.

Methodology: All GP/pharmacy counts from PharmSee /api/location/analyze, 3-mile radius per anchor postcode. Padstow dispensing figure from the NHSBSA-sourced totalRevenue field on the Boots contractor record. The corridor closure-risk classification is a PharmSee analytical judgement, not a PhAS designation.
