Digitising Records, Empowering Clinicians
UHLT Unlocks faster, smarter access to patient records
United Lincolnshire Hospitals NHS Trust is transforming how clinical teams access historic patient records. By digitising thousands of files and integrating MediViewer with their EPR, the Trust is providing secure, real-time access to patient information. This is enabling clinicians, and ultimately improving patient outcomes.

The perfect EDMS project
From those initial exploratory conversations to calculating an economic case and securing funding, devising a scanning strategy, building a project team, mapping out the project plan, configuring your application, driving engagement, mitigating risks, delivering training, overseeing the entire implementation — and a whole lot more — we believe we’ve designed the ultimate strategy for your EDMS project.
It comes from learned — and first hand — experience.


Trusted by the NHS
