W hich is faster?

Reading paper path reports
or scanning electronic docu ments?
W hy standards for E-Path?
(1)
„
The many-to-many connections proble m
„
„
„
5
Assu me 10 nationwide labs need to talk to 50
states
That’s 500 different connections to manage
W ouldn’t it be nice if they all used the sam e
m ethod?
W hy standards for
E-Path? (2)
„
The one-to-many connections problem
„
Labs usually report to many different
departments and agencies
„
„
„
„
„
6
To Hospital m edical records
To billing syste ms
To the ordering physician
To State Health Departments for many diseases
W ouldn’t it be nice if they all used the sam e
m ethod too?

deficient
Propose the m if they are non-existent

Imple m ent E-path
using open rules and procedures
allowing multiple solutions
For adapting to varied environm ents
Analyze the need

Stand-alone path labs required too

Pro motes a system atic evaluation of the
proble m and the solutions

Don’t just apply technology, strategically apply
solutions based on need. “Think Globally, act
locally”
Pro mote standards-based solutions

Critical eye towards content and analysis

M essaging standards are crucial to EPath Reporting
M odeling and Vocubulary standards
crucial as well
E-Path syste m s must integrate with
both hospital and central registries
