Background: While unannounced standardized patients (USPs) have been used to assess physicians' clinical skills in the ambulatory setting, they can also provide valuable information on patients' experience of the health care setting beyond the physician encounter. This paper explores the use of USPs as a methodology for evaluating patient-centered care in the health care system. Methods: USPs were trained to complete a behaviorally-anchored assessment of core dimensions of patient-centered care delivered within the clinical microsystem, including: 1) Medical assistants' safe practices, quality of care, and responsiveness to patients; 2) ease of clinic navigation; and 3) the patient-centeredness of care provided by the physician. Descriptive data is provided on these three levels of patient-centeredness within the targeted clinical microsystem. Chi-square analyses were used to signal whether variations by teams within the clinical microsystem were likely to be due to chance or might reflect true differences in patient-centeredness of specific teams. Results: Sixty USP visits to 11 Primary Care teams were performed over an eight-month period (mean 5 visits/team; range 2-8). No medical assistants reported detecting an USP during the study period. USPs found the clinic easy to navigate and that teams were functioning well in 60% of visits. In 30% to 47% of visits, the physicians could have been more patient-centered. Medical assistants' patient safety measures were poor: patient identity was confirmed in only 5% of visits and no USPs observed medical assistants wash their hands. Quality of care was relatively high for vital signs (e.g. blood pressure, weight and height), but low for depression screening, occurring in only 15% of visits. In most visits, medical assistants greeted the patient in a timely fashion but took time to fully explain matters in less than half of the visits and rarely introduced themselves. Physicians tried to help patients navigate the system in 62% of visits. Conclusions: USP assessment captured actionable, critical, behaviorally-specific information on team and system performance in an urban community clinic. This methodology provides unique insight into the patient-centeredness and quality of care in medical settings.

Background
Newly developed models of health care delivery such as
Patient-Centered Medical Homes (PCMH), Accountable
Care Organizations (ACO) and explorations of the
features of a clinical unit or microsystem that are
associated with high quality care [1] are based on an
appreciation of the impact of the entire care system on
patients health. A central principle of these models is
that care should be oriented around the needs of
patients. Ensuring such patient-centered care requires
understanding how patients experience care from the
moment they walk in the door until they walk back
out, including the range of health care professionals
with whom they interact, the functioning of health
care teams, the ease with which they can find their
way and or get help navigating through the system,
and the quality and safety of the services and care they
receive throughout that process.
Maximizing health outcomes and patient safety requires
a well-designed patient-centered health care system which
includes everyone the patient encountersphysicians,
nurses, clerks and paraprofessionals. High quality care
performed by an individual cannot overcome a poorly
run system or team [2]. Poor functioning teams
contribute to errors such as increased nosocomial infections or
patients not following through on recommended tests
[3-5]. Unfortunately, efforts to address dysfunctional
teams or clinical units are often driven by isolated
incidents or complaints and conducted as post hoc evaluation
that does not capture the real time, routine behavior of
a clinical system. Proactive initiatives to continuously
monitor the quality of the care provided in a clinical
system or unit, from the perspective of patients, are
critical for improving quality.
Current methods for measuring the functioning of the
clinical health system have significant limitations as well
as strengths. Direct observation is intrusive and
therefore may not reflect every-day, actual functioning; in
most contexts, care measured through direct
observation is generally assumed to be of much higher quality
because providers are aware they are being assessed.
However, direct observations use of a highly trained
observer contributes to its status as one of the most
reliable methods for assessing the care that is actually
provided [6-9]. Data collected through patient exit
interviews have often been shown to be biased in
multiple ways, ranging from patients reluctance to judge
their care negatively [10] to the influence of patients
prior experience, expectations, health care status/needs,
and personality [11]. Patient satisfaction surveys suffer
from similar limitations [6,12-14]. However, what both
methods may lack in internal validity can be balanced
by the generalizability benefits associated with
understanding how individuals representative of the targeted
patient population respond to and experience health
care. This trade-off is especially important when the
goal is to understand the impact of health care on
patients. When the focus of the assessment is on the
practices and processes of the health care system,
patient characteristics, on the other hand, can contribute
uncontrolled noise to the equation, making it difficult to
identify how much of health care system responses are
due to specific patient variables and how much are truly
attributes of the system.
We believe that unannounced standardized patient
(USP) visits provide a unique perspective on the
functioning of health care systems because they combine a
number of methodological strengths: 1) they avoid the
Hawthorne effect by capturing the practices of health
care professionals when they are not aware of being
assessed; 2) they involve a highly trained observer/assessor
(the USP); 3) they focus on the vantage point of the
patient; 4) they control not only for the influence of
patient characteristics on recall and evaluation of care
through the use of a highly trained professional but
also, because they are standardized in terms of the
clinical features of the case and the demeanor and
personality of the patient, for the effects of su (...truncated)
