Introduction

• Advancement of processing power and memory
  capacity
• Store/process extensive amount of data in small
  devices
• Possible to store medical data on a personal
  token
• like an USB memory stick.

Motivation 1

• Address the Integration Challenge in healthcare
• Amount of different computer systems in use is
  extraordinary
• Lots of standards exist more systems to handle
  those standards
• Handle heterogeneous and non-standard data
• Heterogenous data that does not comply to
  standards troublesome.
• PMU stores and handles arbitrary data formats and
  lets receiver do semantic interpretation.

Motivation 2

• Use decentralized approach to data integration
• Patient carries data, integrated as needed (meets
  with doctor)
• Use patient as data integrator. Ad-hoc
  synchronize as needed.

Motivation 3

• Ubiquitous data coverage
• Access to medical data requires network
  connection to central data storage
• Practician would need remote access to data
• PMU needs only need local connectivity with
  doctor Benefit while i.e. traveling.

Motivation 4

• Patient empowerment by putting the data in the
  patients hands.
• Proximity based system. Patient approves
  transfers.
• Physical control makes the PMU tangible for
  patients

Features Form 1

• Synchronizes data between PMU and other medical
  systems
• Synchronizes and stores medical data from
  personal monitoring devices.
• Stores personal annotations.
• Can be used in emergency situations.
• Can communicate with systems in its proximity
  using i.e. Bluetooth.

Features Form 2

• Exact form factor of a PMU has not yet been
  designed. Might be a
• USB memory stick
• A necklace
• Other piece of jewelry
• An application running on a mobile phone

Issues Concerns 1

• Signal interference with medical equipment
• Conducted Interference tests to ensure adherence
  to EMC guidelines.
• Data confidentiality
• Digital signature. Patient in control.
• Battery life remains problematic for mobile
  devices
• Sending and calculating data requires power

Issues Concerns 2

• PMU might be
• Lost
• Stolen
• Misplaced
• Left at home when rushing to the hospital
• Medical interventions while patient and a doctor
  are not co-located.
• Elderly and cognitive disabled patients troubled
  by complexity
