We run more than 80 core national systems, and we continue to operate these at extraordinarily high levels of availability and performance. Our most critical services ran at an average of 99.95% availability over the year. Given the scale of the NHS, it is no surprise that we manage more traffic than some of the major national credit card systems and we operate, as far as we can ascertain, one of the largest email systems in Europe.
We are also incredibly excited about the new products and services that we have delivered and the impact that they have had. More than 200,000 people have downloaded the NHS App since it went live on New Year’s Eve, 45,000 of whom have proven their identity and obtained an NHS login that they will be able to use to access multiple services in future.
Our NHS 111 online service has now been used more than 1 million times and the NHS e-Referrals Service currently handles over 70,000 referrals every working day, up from 40,000 at the start of 2018. Our Electronic Prescription Service handled more than 690 million prescription items in 2018-19 and, from February, we included schedule 2 and 3 controlled drugs in the system.
We delivered new services for our colleagues working in medical research, in particular in support of large-scale clinical trials. We commenced a new partnership with Great Ormond Street Hospital focused on addressing long-standing digitisation gaps through smart use of data analytics and commodity technology. We worked with GPs and colleagues in NHS England to reshape the market in primary care IT services.
In addition to the publication of many large-scale open data sets, we disseminated data to over 450 customers in support of more than 1,100 projects across the NHS, academia, industry and the third sector, having reviewed each request in detail to ensure legality, appropriateness, and the compliance of planned handling and management approaches with information governance laws, policies and standards.
We have produced more, and more sophisticated, official statistical series. We have delivered new APIs, worked with international partners to extend open data standard definitions, and provided ever-stronger cyber security services, guidance and support, extending live monitoring to more than 840,000 devices.
