Dear Mark,
Greetings from your "Canadian Cousin",
The information you seek about workload measurement comes from the
Canadian Institute for Health Information. The web site is
<http://www.cihi.ca> click on MIS guidelines. They offer the manual on a
CD for Windows 3.0 or better. This is an electronic book versus paper

Sincerely,
Dan
