Anoto technology – The basics
The Anoto technology is based on two major components:
• The Anoto pattern
• The Anoto Digital Pen

• Pen captures 75 images per second
• Registers:
- Location- Speed of writing- Pressure sensor- Inclination and rotation- Time of use
• Images are used for calculating the current coordinates
• Each coordinate is labelled with a time stamp
• Pen can store up to 400 forms
• Data is transferred via Bluetooth or USB

Seconds:
The use of DP&P in healthcare, three case reports
• Helicopter rescue service in Germany
• Midwives in Portsmouth, UK
• Anaesthetic data capture, Mönchengladbach, GE
ADAC helicopter rescue service in Germany
• Background– ADACs 45 rescue helicopters conduct over 45.000 missions / year
and the need for accurate information is crucial
• Problem/need– Rescue operations must be documented thoroughly, e.g. location,
time and patient data
ADAC helicopter rescue service in Germany
• Solution– A digital emergency doctors log form, a digital pen and a verification
software incl. handwriting recognition
• Advantage– 4 – 5 times faster and error-free data entry– Paper hard copy following patient
• Next step – The “dotforms solution” to be rolled out at all 33 ADAC rescue
centers / 45 rescue helicopters
Midwives in Portsmouth, UK
• Background– Home care of patients is often provided by nurses and midwives– Activities and notes were recorded on paper forms
• Problem/need– Midwives manually filled out an 80 pages maternity visit form– Data was re-entered back at hospital (mistyped, overlooked)– Maternity Notes form stayed with the mother to be, should be
brought to hospital for birth (forgotten, lost)
• Solution– Digital Pen, Maternity Notes form (with Anoto dot pattern) and
BlackBerry smartphone (Bluetooth connected)
Midwives in Portsmouth, UK
• Advantage– Ability to: pull out previous records to check history, use GPS for
directions, message with other midwives and recive alerts
• Results– Private patient data far more secure– Administration time cut in half, from 98 to 48 minutes / care
episode– Annual savings of £220.000– More time with expected mothers
• Next steps– Deployed to 130 midwives (done)– Community Nursing and Accident & Emergency departments next
Anaesthetic Data Capture, Mönchengladbach, GE
• Background– During an operation anaesthetic-related data needs to be
documented quickly and accurately
• Problem/need– The information used to be collected manually with ballpoint pen
and paper and then entered manually into computer back end systems for further processing
• Improvement requirement– An option that enabled handwritten documentation to be entered
straight into the hospital computer system
Midwives in Portsmouth, UK
• ”We have freed up time to care equivalent to five full time midwives”, the solution will ”pay for itself and begin generating savings in the first year, in second and third year it’s all savings.”
Richard Sargent, PHT
Anaesthetic Data Capture, Mönchengladbach, GE
• Solution– A solution built on Digital Pen & Paper technology that allows the
documentation process to remain unchanged– Paper original stays with the patient
• Advantage– As soon as the anaesthetic log is filled in the data is available in
hospital computer system
Healthcare Case reports
Pros
• High quality capture
• Immediately transfers data into system
• Easy to use – same as normal pen and paper!
• Traceability: what paper–what pen–what time
• Rugged and stable technology
• Inexpensive
• Not intimidating, not disruptive
Cons
• Needs electricity (charging)
• Requires well-defined print output control
• Ink can not be erased
• Requires PC or mobile phone for data transfer
• Limited feedback
• Not an open standard
Conclusions
• Provides fast and accurate data capture
• Saves time and money
• Helps provide better care
