Birmingham Women’s and Children’s Hospital NHS Foundation Trust (BWC) is looking to procure an Emergency Call out system to support Birmingham Womens and Children’s Hospital NHS Foundation Trust . It needs to be compliant with all NHS Digital secure data systems and be able to demonstrate resilience in maintaining this service to call out managerial and clinical staff in the event of an incident declared by the Trust necessitating two-way communication to a wide number of staff. The purpose of this pre-market engagement is to support a business case, therefore the Authority is requesting for quotes.
