The Backstory
Big Picture Medical faced the common "compliance drag" of managing complex NHS requirements through fragmented spreadsheets. By implementing the Squirrel™ automated compliance platform and Acorn Compliance’s specialised clinical safety support, they achieved full DTAC compliance in half the expected time. The result was a 50% reduction in costs and a strengthened position to sell to the NHS.
About Big Picture Medical
Big Picture Medical is a global healthtech innovator that unifies patient care across disconnected systems. Through rapidly configurable clinical workflows and GenAI-driven data integrations built on open standards, they create seamless experiences for patients and providers that improve outcomes, reduce operational waste, and simplify healthcare delivery.
The Challenge: Overcoming "Compliance Drag" and Spreadsheet Chaos
Despite their deep understanding of NHS compliance, Big Picture Medical encountered significant operational hurdles that often stall innovators in the UK market:
- The Resourcing Gap: As a growing startup, the team required additional specialised clinical safety expertise to support expanding operations.
- Market Reach Complexity: Changes in the in-house team and the use of disconnected systems made coordinating their product launch difficult.
- The Spreadsheet Trap: Managing the complex DTAC framework through manual spreadsheets led to version-control issues and a lack of transparency.
The Solution: A Unified HealthTech Compliance Platform
To replace "spreadsheet chaos," Big Picture Medical implemented a two-tier approach to bring structure and momentum to their compliance work.
- Squirrel™ Pro: An intuitive platform that replaced fragmented documents with structured, compartmentalised workflows.
- CSO as a Service: Acorn provided an expert Clinical Safety Officer (CSO) to fill the internal resourcing gap and ensure rigorous clinical safety standards were met.
- Rapid Delivery: Acorn managed a "rush" delivery of DTAC and Cyber Essentials Plus, completing within a strict three-month window required after standard Cyber Essentials.
