Pharmacist workforce planning
The planning model
Four inputs that drive your pharmacist headcount
1. List size. The starting baseline is 1 WTE clinical pharmacist per 25,000–35,000 patients. Smaller PCNs (under 40k) often need a senior pharmacist supervisor at higher seniority to make the role sustainable.
2. Frailty cohort. Patients with electronic Frailty Index (eFI) ≥0.24 should receive an annual SMR. A PCN with above-median frailty needs proportionally more pharmacist capacity to deliver the SMR component of the DES.
3. Care home beds. The EHCH DES expects pharmacist input into care home MDT rounds. A working floor is one pharmacist session per care home per fortnight; large or complex homes need more.
4. High-risk drug cohort. DMARD, lithium, amiodarone, methotrexate and DOAC cohort sizes drive monitoring workload. PCNs with high prescribing volume of these drugs need additional pharmacist or technician capacity to maintain over 95% monitoring compliance.

Frequently asked questions
Workforce planning — FAQs
How do you size a PCN pharmacist workforce?+
Start with list size (1 WTE pharmacist per 25–35k patients), then adjust for frailty population (eFI >0.24), care home bed count (one session per home per fortnight as a floor), and high-risk drug cohort size. Add 0.5–1 WTE pharmacy technician per pharmacist for cohort identification and recall.
How does the PCN Workforce Plan link to ARRS claims?+
The PCN's workforce plan should map every ARRS-claimable role to the DES service specifications it delivers against. ICBs increasingly request this map at quarterly contract review; without it, claim audit risk goes up.
What about pharmacy technicians?+
Pharmacy technicians multiply pharmacist capacity by handling cohort identification, recall, monitoring follow-up, repeat prescribing administration and care home medicines administration. A 1:0.5 pharmacist-to-technician ratio is the floor; mature PCNs run 1:1.
How often should the workforce plan be reviewed?+
At minimum twice yearly — once aligned to ARRS budget setting and once mid-year to reflect turnover and DES delivery variance. ICBs typically require a refresh at PCN annual review.
