ABSTRACT
The Hospital Value-Based Purchasing (VBP) Program is a Center for Medicare and Medicaid Services
(CMS) initiative that rewards hospitals with incentive payments for the quality of care they provide to
patients with Medicare instead of the quantity of procedures they perform. Although the VBP program
has direct implications toward both patients and hospitals, no research has been reported in the literature
addressing how hospitals can enhance patients’ experience of care. This research uses systems modeling
to improve the patient experience of care considering the eight dimensions in the Hospital VBP. A case
study is presented that considers three intensive care units from a hospital located in central Texas. The
simulation results show that strategies such as having a quick patient discharge process greatly benefit the
hospital in terms of how patients perceive quality of care as measured by the Hospital Consumer
Assessment of Healthcare Providers and Systems (HCAHPS) survey.
1 INTRODUCTION
Delivering patient-centered care is an important component of a high-quality healthcare system (Baker
2001). In 2010 the Hospital Value-Based Purchasing (VBP) was established to link Medicare’s payment
system to a value-based system that focuses on the patient. Under the VBP, healthcare systems are
evaluated not only on the patient outcomes but also on the patient experience of care while in the hospital.
The VBP program uses the Hospital Consumer Assessment of Healthcare Providers and Systems
(HCAHPS) survey to measure patient experience of care. The results of the survey are used to incentivize
hospitals that perform according to the VBP goals. The best hospital performers are incentivized up to 1%
of their annual earnings. That incentive amount is expected to double by 2017. Therefore, it is imperative
for hospitals to consider new strategies to serve patients while considering both, patient outcomes and
patient experience of care.
The HCAHPS survey is a 27-part questionnaire that is currently used as the standard tool to quantify
patient’s experience. The survey takes into account eight different dimensions including nurse
communication, doctor communication, cleanliness and quietness, responsiveness of hospital staff, pain
management, communication about medicine, discharge information, and overall rating. Currently, we
know little about the relationship between hospital performance and patient satisfaction (Tsai et al. 2015).
As national policy efforts, such as VBP are implemented, understanding the potential tradeoffs between
patient satisfaction and measures of efficiency of hospital system factors become very important.
In this paper, a discrete-event simulation is developed to model the patient interactions with doctors
and nurses in three intensive care units (ICUs) of a hospital located in Central Texas. The objective of the
study is to provide insights about the impact of hospital system factors on the patient experience of care as
measured by the HCAPHPS survey. The system factors considered in this study include patient
