Who is Eugene Litvak? Eugene Litvak, Ph.D. is a Professor of Health Care and Operations
Management
and Director of the “Program for the Management of
Variability in Health Care Delivery”

at Boston University Health Policy
Institute. His primary research interest is, as the foregoing would
suggest, identifying and managing natural and artificial variability.
(Select publications here.)

Hospital care will never be a “just in time” operation. Patients and
their health are not a raw material to be scheduled and metered out at
a precisely controlled rate. In the overall delivery of care however,
variability comes in two flavors: “natural” variability which cannot be
controlled, and “artificial” variability which can be controlled. Queuing theory
can be used to manage natural variability. Artificial variability comes
from batching, blocking and other techniques that are commonly used to
manage workflow.

The following are some key papers on managing variability to improve patient flow:

Variability in Surgical Caseload and Access to Intensive Care Services, Anesthesiology Volume 98(6) June 2003 pp 1491-1496 (full text)

Managing Unnecessary Variability in Patient Demand to Reduce Nursing Stress and Improve Patient Safety, Joint Commission Journal on Quality and Patient Safety, June 2005, vol. 31, no. 6, pp. 330-338(9) (full text $20)

Root Cause Analysis of Emergency Department Crowding and Ambulance Diversion in Massachusetts,
A report submitted by the Boston University Program for the Management
of Variability in Health Care Delivery under a grant from the
Massachusetts Department of Public Health, October, 2002 (full text)

Emergency Department Diversion: Causes and Solutions, Academic Emergency Medicine, November 2001, Volume 8, Number 11, pp. 1108-1110, (full text)
