Andy Charlwood -- Comprehensive Career & Portfolio Reference
MPharm, GPhC Registered Pharmacist Norwich, UK | andy@charlwood.xyz | https://andy.charlwood.xyz/
The Origin Story
Andy is a pharmacist who taught himself to code during quiet night shifts at Tesco Pharmacy. He built a prescription-checking automation before he fully realised that combining clinical knowledge with programming was unusual. That combination has shaped his entire career since, taking him from a community pharmacy in Great Yarmouth to leading population health analytics for an NHS system serving 1.2 million people across Norfolk and Waveney.
The self-teaching wasn't a formal programme or a course. It came from a drive to find root causes in data and build the most efficient solutions to complex problems. Over about a decade, that drive turned into genuine proficiency in Python, SQL, Power BI, and later JavaScript and TypeScript.
Current Position
Deputy Head, Population Health & Data Analysis NHS Norfolk & Waveney ICB | Jul 2024 -- Present | Norwich, England
Andy drives the data analytics strategy for medicines optimisation across Norfolk & Waveney Integrated Care System. He develops bespoke datasets and analytical frameworks from messy, real-world GP prescribing data to identify efficiency opportunities and address health inequalities.
He reports to the Associate Director of Pharmacy and Medicines Optimisation, with presentation accountability to the Chief Medical Officer and system-level programme boards.
Key responsibilities include managing a £220M prescribing budget with sophisticated forecasting models, leading data infrastructure development, and translating complex clinical, financial, and analytical requirements into clear recommendations for executive stakeholders.
Previous: Interim Head, Population Health & Data Analysis
NHS Norfolk & Waveney ICB | May -- Nov 2025
Andy was appointed Interim Head when his previous manager retired at the end of December 2024. He was effectively performing the role from January 2025 but was only formally appointed and paid at Interim Head rate from May 2025. The role ran for approximately 10 months total (5 months formally). He returned to his substantive Deputy Head position following commencement of an ICB-wide organisational consultation, which paused permanent recruitment due to potential redundancies. This was a structural/organisational change, not performance-related.
During this period he presented strategy, programme progress, and financial position to the Chief Medical Officer on a bimonthly basis.
Key Achievements & Metrics

Major Projects (Detailed)
1. PharMetrics -- Automated Switching Algorithm
The Problem: The medicines optimisation team ran an annual switching scheme to identify cost-effective medication alternatives. This previously took months of manual work, with a team of people searching tools like OpenPrescribing for opportunities such as new generics, price drops, or better-value alternatives.
The Insight: Andy recognised this was highly automatable. With access to patient-level prescribing data through the ICB dataset, he could theoretically identify the most cost-effective switches on a per-patient basis, optimising for the minimum number of patients to switch for the maximum financial saving.
The Solution: A Python-based algorithm that ingests real-world GP prescribing data and automatically identifies patients on expensive drugs suitable for cost-effective alternatives. It calculates which switches give the best return on intervention.
Development Process: Andy built this independently with a high degree of autonomy. He didn't need formal sign-off to develop it. Once the analysis was complete, he engaged the wider medicines optimisation team for clinical sign-off on the final switch list, which took approximately 3 days versus the previous months of manual work.
The Novel Payment System: Andy designed a unique incentive structure for the GP switching scheme. The GP incentive amount varies based on the savings delivered from each switch: higher-value switches earn a higher incentive payment, lower-value switches earn less. This incentivises GPs to prioritise the highest-impact changes first.
Monitoring: Andy created dashboards tracking patient-level switching data, monitoring which patients have been switched (or are no longer prescribed the target drug), with quality metrics providing points for each patient intervention (deprescribing, formulary alignment, or other optimisation). He wrote SQL searches to create specific targeted patient cohorts and built dashboards so practices could monitor their own progress.
Impact: Transformed months of manual work into a 3-day automated process. Identified 14,000 patients for intervention. £2.8M maximum potential savings. 50% reduction in targeted prescribing within first 2 months. The tool is internal, used by the medicines optimisation team to inform system-wide incentive schemes.
GP Adoption: Generally good engagement driven by financial incentive. Some complaints about difficult patients and workload pushback, but the payment structure and targeted approach keep engagement high.
2. Patient Pathway Visualisation (Sankey Charts)
The Problem: NHS trusts needed to understand how well they were aligned to agreed clinical pathways for high-cost drugs. There was no way to visualise patient journeys through treatment sequences.
The Solution: A Python-based tool that ingests years of patient-level prescribing data and creates Sankey charts showing patient journeys through treatments (Drug A to Drug B to Drug C to Drug D). This visualises how well trusts align to written pathways and identifies where patients deviate from expected treatment sequences.
Impact: An external-facing tool provided to local trusts. Trusts can understand their own positioning, identify opportunities for improvement, and see which specialists need to be engaged. Enables data-driven discussions about pathway adherence. Used for audit and compliance purposes.
3. Controlled Drug Monitoring System
The Problem: The team needed to identify high-risk opioid users, track total opioid exposure over time, and identify potential diversion (medications being sold rather than used). This analysis was previously impossible at patient level.
The Solution: A Python-based system that takes all opioid prescriptions in the system and calculates oral morphine equivalents for each drug. It tracks patient-level opioid exposure over 6--9 months, identifies patients with dangerously high total exposure, and flags potential diversion risks.
Impact: Supports the controlled drug assurance element of the medicines optimisation work. Identifies high-risk patients for intervention. Previously impossible analysis is now routine. Improved patient safety monitoring and better targeting of support services. Enables population-scale patient safety analysis.
4. Comprehensive Medicines Data Table
Developed with: ICB data engineering team
What it contains: All medicines currently available on the dm+d (Dictionary of Medicines and Devices), with standardised drug strength calculations (returning the amount of grams of active ingredient in each product for direct product-to-product comparison), opioid morphine equivalent calculations for all opioid medications, and Anticholinergic Burden (ACB) scoring.
Why it matters: Functions as a lookup table where you can find the cheapest formulation with a single minimum value search. Serves as a single source of truth for all medicines analytics across the system. Democratised access to data, enabled more targeted interventions, and created a self-serve model that reduces bottlenecks.
5. Blueteq Prior Approval Automation
The Problem: High-cost drugs required prior approval through Blueteq forms. The process was bureaucratic and time-consuming for both the ICB and clinical stakeholders.
The Solution: Software that automates Blueteq prior approval form creation. Also integrated Blueteq data with secondary care activity databases, resolving critical data-matching limitations.
Impact: 70% reduction in required forms. 200 hours immediate savings. Ongoing 7--8 hours weekly efficiency gains. Enabled accurate high-cost drug spend tracking.
6. DOAC Switching Programme -- Financial Scenario Modelling
Andy led financial scenario modelling for a system-wide DOAC (Direct Oral Anticoagulant) switching programme, building an interactive dashboard incorporating rebate mechanics, clinician switching capacity, workforce constraints, and patent expiry timelines to quantify risk trade-offs for senior decision-makers.
He also led renegotiation of pharmaceutical rebate terms ahead of patent expiry, securing an improved commercial position for the ICB.
7. Tirzepatide Commissioning (NICE TA1026)
Andy supported the commissioning of tirzepatide, including financial projections identifying eligible patient cohorts from real-world data. He authored the initial executive paper advocating a primary care delivery model over a specialist provider on cost-effectiveness and accessibility grounds. This drove the system's shift to a GP-led model following executive sign-off.
8. Incentive Scheme Analysis Automation
Andy automated the previously manual incentive scheme analysis, improving accuracy and targeting precision. This enabled the novel GP payment system linking rewards to delivered savings, which achieved the 50% reduction in targeted prescribing within the first two months.
High-Cost Drug Pathways
Andy wrote most of Norfolk & Waveney's high-cost drug pathways, balancing legal requirements to implement NICE Technology Appraisals against financial costs and local clinical preferences. He engaged clinical leads across all sectors of care to agree pathways and secure system-wide adoption.

Leadership & Management Style
Philosophy
Andy's leadership approach centres on coaching, autonomy, and leading through expertise rather than positional authority. His entire career has been about changing processes and improving efficiency, and every process change requires coaching and change management. His core principle: you have to take people with you.
Key Examples
No-Blame Culture (Community Pharmacy): Embedded a culture where everyone has a valid opinion regardless of hierarchy. Created an environment where people feel free to speak up and challenge authority. Dismantled traditional hierarchical barriers while maintaining necessary governance structures. Recognised that for safety issues, everyone has a valid perspective on human behaviour.
Autonomy-Based Working (ICB): High degree of autonomy in how people work. Minimal micromanagement. People given direction on what needs to be done but freedom in how to achieve it. Leading through expertise and guidance rather than authority.
Leading Without Formal Authority:
- Weight management service development: leading clinical voice in pathway development, leading bid for funding, subject matter expert providing direction with no formal authority over the people looking to him for guidance
- Cross-trust pathway implementation: engaging specialists, GPs, chief pharmacists across multiple organisations to secure adoption of new pathways
Team Transformation: Led the change from practice-level EPACT data to patient-level SQL analytics. A long process requiring sustained coaching and support, providing training and framework to enable team growth, pointing team members to relevant training resources, removing barriers and blocks to development.
Staff Development: Supervised two staff members through NVQ3 qualifications to pharmacy technician registration. Trained all new pharmacy staff at Tesco (internally recruited from other departments) requiring significant upskilling.
