Quality Accreditation

Multilex has been designed and built by UK clinicians and is maintained by a team of in-house clinical experts, pharmacists and a dedicated integration team, all based in the UK.


Improve Patient Safety

Multilex integrates into electronic patient record (EPR) and e-prescribing systems to support active clinical checking against a patient’s medication record. This integration gives clinical staff the support and information required to safely prescribe the most appropriate medications. The real-time clinical alerts and warnings highlighted within the e-prescribing process assist in reducing the risk of medical errors.


Reduce Dosing Errors

Multilex includes predefined, patient-specific, dose order sentences that can be used to help reduce over and under-dosing. The intelligent dose algorithm uses patient data such as age, weight, body surface area to determine appropriate drug doses. Multilex enables in-built checks of doses before the prescription is confirmed (including dose range check and cumulative dose check) to ensure that the risk of medication dose error is reduced.

Improve Clinical Efficiency

The Multilex drug database is reviewed, updated and interpreted by an in-house team of clinical pharmacists and researchers, ensuring fully quality checked, evidence-based medicines information. Integrating Multilex into an e-Prescribing and Medicines Administration (ePMA) system delivers this information to the point of care, enabling faster medication checks and giving busy clinical staff the confidence they are using current medicines guidance.


Ensure Interoperability

Multilex facilitates interoperability between systems by integrating a wide range of clinical terminologies including the NHS Dictionary of Medicines and Devices (dm+d) and SNOMED CT. Multilex also includes the medication data structure and barcode information that underpins a closed-loop e-Prescribing and Medicines Administration (ePMA) system.
