In England alone, this includes 211 clinical commissioning groups, 156 acute trusts, 56 mental health trusts, 34 community providers, 10 ambulance services, 8,000 GP practises and 2,300 hospitals. It employs 1.6 million people throughout the UK and sees one million patients every 36 hours. For an organisation of this size, efficient, effective and secure communications is essential.
