Why clinical pharmacists are the highest-leverage ARRS role for PCNs
Clinical pharmacists are the most-claimed ARRS role in England by headcount and by reimbursement value, and they are the only role that directly delivers against three PCN DES service specifications simultaneously: Structured Medication Reviews and Medicines Optimisation, Enhanced Health in Care Homes, and Anticipatory Care. No other ARRS role has that breadth of contractual fit.
For a PCN Clinical Director, the calculation is straightforward: a well-deployed clinical pharmacist releases 4–6 hours of GP appointment time per clinic session, completes 120+ SMRs per year per WTE, closes prescribing safety alerts to ICB-required timelines, and unlocks DES achievement payments that would otherwise be at risk. The hard part is not the business case — it is mobilising, supervising, retaining and reporting on the workforce at network scale.
Most PCNs we work with have done the recruitment once, struggled with turnover and supervision capacity, and moved to a managed-service model by year two. This page describes both routes — in-house and outsourced — so the Clinical Director can choose with full visibility of the trade-offs.
Workforce sizing
Benchmarks for PCN pharmacist deployment
What the PCN owns
PCN responsibilities under the Network Contract DES
- Maintain a workforce plan that maps ARRS roles to DES service specifications
- Appoint a Clinical Director accountable for clinical governance across the network
- Ensure every ARRS role has a designated supervisor and documented scope of practice
- Submit accurate ARRS claims monthly via the CQRS portal
- Evidence SMR delivery against the DES population target (frailty, care home, high-risk cohorts)
- Maintain SEA, prescribing safety alert closure and complaint handling at PCN level
- Engage with ICB medicines optimisation team on prescribing quality and cost benchmarks
In-house vs outsourced
The two delivery models, side by side
In-house gives the PCN full ownership and (in theory) lowest cost, but requires HR, recruitment, supervision capacity and cover for sickness or turnover. Outsourced via a managed-service provider trades a small margin for full workforce continuity, weekly senior supervision, QA sampling, CPD and ICB-ready reporting — with the role still ARRS-claimable. See our full comparison for the financial breakdown.
- In-house: PCN owns HR, supervision, cover, CPD, reporting
- Outsourced: provider owns all of the above; PCN retains clinical accountability
- Hybrid: most mature PCNs run 1–2 in-house pharmacists plus 1 BCS-supplied to absorb turnover and cover
- ARRS reimbursement applies in all three models if supervision and scope evidence is in place
Frequently asked questions
Clinical pharmacists for PCNs — FAQs
How many clinical pharmacists does a PCN need?+
Plan against list size, frailty cohort and care home population. As a rule of thumb most PCNs deploy 1 WTE clinical pharmacist per 25,000–35,000 patients plus 0.5–1 WTE pharmacy technician. Care-home-heavy PCNs and atypical demography (e.g. coastal frailty, deprivation, large student populations) skew this materially.
Does the PCN DES mandate clinical pharmacist provision?+
Yes. The Network Contract DES service specifications for Structured Medication Reviews, Enhanced Health in Care Homes and Anticipatory Care all assume clinical pharmacist capacity. ARRS reimburses the role, and ICBs increasingly require evidence of supervision and clinical activity to sign off DES achievement.
Who employs the PCN clinical pharmacist?+
Most commonly the lead practice, the PCN's incorporated entity (e.g. GP federation), or a managed-service provider like BCS that supplies the workforce under an ARRS-claimable contract. The choice affects HR, indemnity routing and cover for sickness or turnover, but not the funding mechanism.
How does a PCN supervise pharmacists working across multiple practices?+
Most PCNs appoint a Lead Pharmacist (often senior IP-qualified) who provides weekly clinical supervision, signs off scope of practice and reviews QA samples. Where the PCN lacks senior pharmacist capacity, a managed-service provider supplies the supervision layer alongside the workforce.
What KPIs should the PCN Clinical Director ask for?+
Clinical: SMRs completed against PCN DES target, high-risk drug reviews, discharge reconciliation within 7 days, prescribing safety alert closure. Operational: utilisation, DNA rate, cover days lost. ARRS-compliance: supervision evidence, scope of practice currency, indemnity confirmation, claim accuracy.
