Real Time Locating Systems (RTLS) implementations have increased in the
healthcare industry despite few studies supporting efficacy. In addition, the
potential applications of RTLS as a tool for improving hospital operations
management remains relatively unexplored. We sought to measure the
improvement in quality of care and patient experience immediately after RTLS
implementation. Furthermore, we explored the utility of RTLS in providing
unbiased data to improve accuracy for chemotherapy scheduling. Finally, we
demonstrate the ability for RTLS to assess impacts of large organizational changes
such as the implementation of an Electronic Health Record on patient time in
clinic.

Panel: Challenges of Implementing OR in the
Healthcare Industry
Invited: ORinformed Healthcare Policies
Invited Session
Moderator: Michael W Carter, University of Toronto, Toronto, ON,
Canada,
Implementing OR/MS in healthcare poses major challengers to practical
researchers. The problems and the corresponding solutions are similar to those in
industry and other service industries. So why is it so difficult? This panel brings
together a group of researchers who have been successful in overcoming the
challenges.

1 - Optimal Liver Cancer Surveillance In Hepatitis C
Infected Population

Liver cancer is the fastest growing cause of cancer deaths in the United States.
Although early diagnosis through can improve survival, the optimal surveillance
policy remains unknown. We develop a mixed-integer programming-based
framework to identify the most cost-effective surveillance policy. Our framework
allows a formulation of practical policy structures. Our numerical results find that
(1) the optimal surveillance interval should depend on patient’s stage of hepatitis
C and age, and (2) expanding surveillance to earlier stage of hepatitis C improves
the cost-effectiveness of HCC surveillance.
2 - The Changing Etiology Of End Stage Liver Disease And The
Implicationsfor The Liver Transplant Waitlist
Maria Mayorga, North Carolina State University,
Zinan Yu, Stephanie B Wheeler
Changes in the epidemiology of end stage liver disease will impact future liver
transplant (LT) waitlist. We performed a discrete event simulation model to
forecast both regional and national LT waitlist size, number of transplants, and
hazard of waitlist drop out, while considering patient arrivals, demographic and
clinical attributes, waiting time and liver availability.
3 - Investigating Steroid Withdrawal Strategies For Kidney
Transplant Recipients

We evaluate various steroid withdrawal strategies for kidney transplant recipients.
The goal is to minimize major complications resulting from these complex drug
regimens over the long term. We develop a model calibrated with an econometric
study of patient data from a national registry to simulate the long-term course of
these patients. We report on the frequency and timing of adverse events and
identify trade-offs in the steroid withdrawal strategies.
4 - Eliciting Patients’ Revealed Risk Perceptions Of Dialysis And
Death In Preemptive Living-donor Kidney Transplantation
Masoud Barah, University of Tennessee, Knoxville, TN,
United States, , Anahita Khojandi,
Murat Kurt
When kidneys can no longer function at the level needed, patients must undergo
either dialysis or transplantation to survive. Given empirical patterns in timing of
pre-dialysis living donor transplantation, we investigate the behavioral dynamics
behind patients’ risk-averse behavior. We develop an inverse MDP model to elicit
the perceived life-year loss associated with kidney failure or death due to delaying
transplantation. We calibrate the model using clinical literature and publicly
available datasets and provide insights on patients’ perceptions of kidney failure
and risk of death.

1 - Intra-firm Spillovers? The Stock And Flow Effects Of Collocation
Evan Rawley, Columbia Business School, New York, NY,
United States, Robert Seamans
We study how intra-firm collocation—geographic clustering of establishments
owned by the same parent company—influences performance, decomposing
collocation effects to learn about the mechanisms behind intra-firm
agglomeration. Using Census micro data on the population of U.S. hotels and
restaurants 1977-2007, we find that doubling the intensity of intra-firm
collocation is associated with a productivity increase of about 2%. Further
analyses reveal that a significant component of the productivity gains persist after
an establishment ceases to be collocated, suggesting that proximity to other
establishments owned by the same parent firm facilitates the transfer of
knowledge.
