David patterson: Continuing development of the community based anticoagulant and stroke prevention services
1. Continuing development of the
community based anticoagulant and stroke
prevention services
Progressing towards
A STROKE PREVENTION SERVICE (AF AND AC)
Transition from successful pilot services towards more robust and
expanding services
21 November 2011
Professor David Patterson, Professor Dipak Kalra,
Department of Cardiovascular Medicine and Pharmacy, Whittington Health
Centre for Health Informatics and Multiprofessional Education, University College London
2. Electronic Health Record (EHR)
Supporting clinical shared care across organisations
Building on ~20 years of European research
Conforms to the latest international standards
Robust medico-legal and confidentiality features
Standards for clinical knowledge capture enable meaningful clinician
developer interaction and rapid development
Implemented as a web based system
Incorporates decision support and alerts
Cardiovascular modules
•HeartBeat AC: anticoagulation - in live use
• HeartBeat HF: heart failure - ready for live use
• HeartBeat AF: atrial fibrillation - clinical engagement commencing
3. Clinical Governance report
Derived automatically from the EHR
Each site can run its own report at any time
All reports include anonymous service-wide comparisons
Reviewed at quarterly Clinical Governance Board meetings
4. North Central London Community Based
Anticoagulant and Stroke Prevention Services
PROGRESSING TOWARDS
A STROKE PREVENTION SERVICE (AF AND AC)
• Enhancing our ability to prevent patients developing strokes
• Progressed from a doctor delivered service in hospital toward an
increasingly community based service
• Delivered by practice nurses, community pharmacists and GPs,
supported by a state of the art information and advisory system
which uses an Electronic Health Record
• A strong focus on education and on clinical governance
• Our services have been shown to be safe and very well received
by the patients, by the commissioners of health services and by the
community staff
5. Forgetful, elderly person with diabetes, atrial
fibrillation, heart failure and mild aortic valve
stenosis, who lives alone in
poor housing and requires anticoagulation
• Multiple chronic conditions
• Multiprofessional care
• Shared information needs - across boundaries
• Interface with other organisations:
– Social services
– Housing
– Voluntary sector
– Ambulance/car services
– Primary/secondary/tertiary care
6. Development of advisory systems for warfarin
dose and follow-up interval guidance
• CONTEXT - 1
• In latter part of 20th Century – warfarin management
was a doctor delivered service in hospital environment
• Regarded as dull and unchallenging
• Often performed by the most junior doctor with little
experience of anticoagulation
7. Development of advisory systems for warfarin
dose and follow-up interval guidance
• CONTEXT - 2
• And yet
• Developing realisation that warfarin was potentially a
dangerous drug influenced in its effects by many
factors such as diet and use of other drugs
• Increasing evidence that there was an unacceptably
high morbidity and death directly related to warfarin
• Very poor communication between health
professionals when introducing a new drug or starting
new treatment for a patient
8. [1] Evaluation of a decision support system for initiation
and control of oral anticoagulation in a randomised trial
[2] Validation of an algorithm for oral anticoagulant dosing
and appointment scheduling
• [1] The computerised decision support system was safe and effective
• It improved the quality of initiation and control of warfarin by trainee
doctors
• [2] The algorithm performs better than inexperienced clinicians and
as well as experienced clinicians for the non-difficult patients
• Algorithm better at recognising the more difficult case than the non-
expert (ie to see doctor)
• Analysis of combination of dose and interval recommendation showed
remarkable similarity between experts and algorithm
