Complex Systems

• Many parts, Many interactions• Perpetual novelty

• Difficult to describe/understand completely• Difficult to control/change

• Identify simple rules– Self-organise

• e.g. Weather, Economy, Internet, ED

National Health Service in the UK

• Established in 1948 by Labour Government

• Huge– 3rd largest employer in world, largest in Europe, 1 million+ staff– 45+ million patients in England

• Healthcare free to all at the point of care

• Quality

• Costly– Increasingly financially oriented– “Payment by Results”

• “NHS Plan” = Service Reform (inc. IT)– e.g. Leeds Teaching Hospitals

• City <1million population• 4 EDs; 110,000 + 90,000 census• 95%/98% “4 hour ED target”…

• Biggest civil IT programme in world• 10 year; based in Leeds, England• $20+ billion with commercial suppliers

• 5 Regions of England– North East Cluster

• 7.5 million population• 170,000 NHS staff• 23 Acute Hospitals• 12 Mental Health Trusts• 1200+ Primary Care practices

– Care Record Service • contract £1 billion

• Hugely ambitious

• Primary, Community, Hospitals, Mental Health– Contracts for several interim solutions– Aiming for a single strategic EHR solution

• National Services– Single NHS patient identifier number– Service Directory– Choose and Book scheduling

• Local Services– Care Record Service (Electronic Health Record)

• Guideline based • Workflow integrated • Cross organisational working

NHS + IT = Complex

Change – Emergency Medicine

Change - Management

Benefits = Quality

Risk↓ Cost↓ Time↓

Drivers

Change - Software Engineering

People+ Process + Technology in a “Model Community”

Systems in Silos

• People– Challenge siloed thinking

• Process– Look for simplicity within the complexity– ? Core generic processes in healthcare

• Technology– Evolutionary approach– Process related IT requirements

• esp. at the complex front end. i.e. ED charting– free text/dictation versus forms (e.g. T-system)

• Aim to reuse– Distributed process-oriented SOA?

• Balance central control and local innovation

Process - Urgent Care Study • Identify top/core business processes in Urgent Care• Identify and prioritise information/technology needs

• Methodology– Stakeholders/ core Processes / IT Requirements

• Site visits– NHS Direct– Ambulance Services – ED (4 in West Yorkshire)– Walk in Centre– GP Out of Hours

This may also be done by contacting NHS Direct

Concern(s) may be identified by the patient, a carer, a bystander, an attendant (e.g. police at an RTA) or a care professional. So may the provider contacting & service requesting, e.g. if the patient is unconscious.

This overview of urgent care is compatible with the submodels provided for each urgent care provider. However it explicitly shows some of the detail which is within each of the submodels . The detail shown deals with assessing the appropriateness of the care request by each provider, and the passing of the patient to another provider if further urgent care is needed that is outside the scope of the current provider.

May include 1 or more attendances atED clinics after initial attendance

A tale from Denmark …

The Danish solution…

• 15+ years of European & Australian R&D

• Generic Process based EHR Architecture

• Related to – European Standard

(en13606)– ISO standard

OpenEHR

Archetypes

Generic

Specific

Archetype

• Reusable list of clinical statements

• Useful for clinical documentation

• Can be coded with terminologiese.g. Snomed CT

Archetypes & Templates

•Central control

•Local flexibility

Archetypes

• North, Midlands and East– 60% of England

• Supplier– Contract with CSC– Single strategic EHR solution– Requirement & Design Stage

• NHS “Clinical Content” needed– To support charting

• Big Opportunity

Phases of Content Delivery

NHS input… example..

NHS content – inputs via wiki

• Collaborative• Evolvable

• Version control

• comments

NHS input… e.g. Head & Neck examination

Into Head & Neck exam archetype

Archetypes can bind to codes…

Archetypes available as XML/HTML etc…

NHS Archetype library

Archetypes configured in Templates solves central control + local need

Template editor output as HTML/XML/Forms etc….

Templates (Toys)OpenEHR content

• Can be used for application UI – e.g. forms

• Can be transformed into messages– e.g. HL7 CDA

• Can be used for querying +/- Terminology

openEHR content cycle..

• Clinical content will continue to evolve

• Archetypes and templates are version controlled

• Content changes – don’t impact application – if fit with openEHR

Benefits of Archetypes• Quality

– Better documentation - for complexity of healthcare • Via Standard Archetype + Flexible Templates

– Can evolve over time - as medicine changes• Via version control

– Balances central control and local innovation• Risk

– Solid foundation for Decision Support• Time

– Save time• Build templates fast

• Cost– Save NHS money

• Standard methodology – all can share• Non proprietary

NHS Clinical Content Service

• NHS Requirements• E-Care Pathways • Archetypes & Templates

– Archetype outputs 150+– Template outputs 20+

• Clinical Coding– Via SNOMED CT

• Resource• Governance

Key issues….• NHS IT

– Hugely ambitious– Learning valuable lessons

• People issues– How to involve the right people

• Think beyond current silos– Governance

• Local versus National?

• Process issues– look for the generic within

• Technology issues– Evolutionary – Clinical process oriented approach i.e. archetypes– Ensures clinical content is reusable/evolvable
