9 Hospital Information Systems A HIS meets the real-time operational information needs of health professionals to deliver care to patients, whilst also providing accurate and timely information for management purposes.

10 HIS Benefits Improved care and delivery of services provided to patients Reduced administrative work Better information for resource management

11 HIS Functional areas (used by 1500 staff) Patient Administration Admissions, Discharges and Transfers Accident & Emergency Maternity Operating Theatres Professions Allied to Medicine Case Note Tracking Contracting & Billing

17 Information for Health An Information Strategy for the Modern NHS

18 Top level commitment The challenge for the NHS is to harness the information revolution and use it to benefit patients. Rt. Hon. Tony Blair All Our Tomorrows Conference 2 July 1998

19 Purpose of the strategy.... to put in place over the next seven years the people, the resources, the culture and the processes necessary to ensure NHS clinicians and managers have the information needed to support the core purpose of the NHS. And to ensure the public and patients have a range of quality information easily accessible about health and health services.

20 Treatment and care Primary care EHR Public Patients Healthcare professionals Managers Knowledge for Public health Clinical Governance Health Improvement Programme Performance management Analysis Social care records NHS Trust EPR

21 Defining electronic records è Electronic Patient Record - a record of periodic care provided by one institution, typically an acute hospital è Electronic Health Record - the concept of a longitudinal record of a patients health and healthcare to combine information from primary healthcare with periodic care from other institutions

22 4 Key Pieces of the Strategy Better Practice Systems + Electronic Health Record ( EHR ) Better Hospital Systems + Electronic Patient Record ( EPR ) National Electronic Library of Health ( NELH ) INFRASTRUCTURE (wires,security,standards)

43 Magnetic Resonance Imaging Protons in a magnetic field have a microscopic magnetization and act like tiny toy tops that wobble as they spin. The rate of the wobbling or precession is the resonant or Larmor frequency. In the magnetic field of an MRI scanner there is approximately the same number of proton nuclei aligned with the main magnetic field as counter-aligned. On a macroscopic level, exposure of an object or person to RF radiation at the Larmor frequency, causes the net magnetization to spiral away from the static field. Relaxation is the process whereby nuclear magnetization returns to its resting state following a perturbation, such as by an RF pulse.
