ABSTRACT: We examined the association between JCAHO accreditation of hospitals, those
hospitals' quality of care, and survival amo ng Medicare patients hospitalized for acute
myocardial infarction. Hospitals not surveyed by JCAHO had, on average, lower quality (less
likely to use aspirin, beta -blockers, and reperfusion therapy) and higher thirty -day mortality rates than did surveyed h ospitals. However, there was considerable variation within accreditation
categories in quality of care and mortality among surveyed hospitals, which indicates that
JCAHO accreditation levels have limited usefulness in distinguishing individual performance
among accredited hospitals. These findings support current efforts to incorporate quality of care
in accreditation decisions.
THE JOINT COMMISSION on Accreditation of Healthcare Organizations (JCAHO) is an
independent, not -for -profit organization that is the nation's leading accreditor of hospitals.1
Obtaining JCAHO accreditation is important for hospitals, as the Medicare Act of 1965 decreed
that accredited hospitals were deemed to have satisfied federal health and safety requirements
necessary to partici pate in Medicare.2 Hospitals also have considerable incentive to become
accredited for marketing purposes, often using JCAHO accreditation as a "thirdparty
endorsement of quality."3 As a result, approximately 80 percent of the 6,000 U.S. hospitals have
sou ght JCAHO accreditation.4
JCAHO accreditation is awarded on the basis of a hospital's compliance with a set of standards,
which surveyors use in assessing performance during hospital site visits.5 Standards are assessed
in patient assessment and care, pat ients' rights, clinical ethics, organizational leadership, human
resources management, and information management.6 JCAHO's philosophy is that "if hospitals
complied with relevant standards then hospitals would be likely to achieve good outcomes."7
However , evidence demonstrating that JCAHO accreditation can distinguish differences in
hospitals' quality of care or patient outcomes is limited. Studies have found little correlation
between accreditation and general hospital mortality, and no differences in ra tes of medication
error between accredited and nonaccredited hospitals.8 However, a robust assessment of whether
JCAHO accreditation correlates with disease -specific quality measures has yet to be conducted.
Acute myocardial infarction (AMI) is well suite d for a study of accreditation because it is a
common diagnosis and a major cause of mortality for which quality performance measures have
been established from authoritative clinical guidelines. The availability of data from the
Cooperative Cardiovascular Project (CCP), a national project to assess and improve the care of
Medicare patients hospitalized with AMI, provides a unique opportunity to assess whether
JCAHO hospital accreditation is associated with use of guideline -recommended therapies and
clinica l outcomes.
Study Methods
* JCAHO accreditation. A hospital seeking to obtain JCAHO accreditation is visited every three
years by a survey team that observes hospital operations, conducts interviews, and reviews
medical documentation for compliance with a set of standards in forty -five performance areas.9
JCAHO surveyors assign a score in each performance area and determine an "accreditation
level" based on a hospital's overall score and whether JCAHO cited specific areas for
improvement (for example, typ e I recommendations, which indicate the need to resolve
unsatisfactory compliance). JCAHO accreditation levels during our study period were (in
descending order of compliance) accreditation with commendation, accreditation without (type I)
recommendations (hereafter referred to as "accreditation"), accreditation with (type I)
recommendations, conditional accreditation, and not accredited. We obtained data from JCAHO on hospital accreditation level and summary scores for hospitals surveyed between 1994 and
1998. Hospitals that had neither a summary score nor an accreditation level reported were
considered to be not surveyed.
* Cooperative Cardiovascular Project. The CCP sample included 234,769 feefor -service (FFS)
Medicare hospitalizations from acute care, n ongovernmental hospitals with a principal discharge
diagnosis of AMI, excluding readmissions for AMI, between January 1994 and February 1996 in
all fifty states and the District of Columbia.10 Medical records of sampled patients were
abstracted for patient s' clinical characteristics, in -hospital treatments, and vital status.
Our study consisted of CCP patients age sixty -five and older who were hospitalized with
clinically confirmed AMI. We excluded patients who did not have confirmed AMI (n = 31,186),
were younger than age sixty -five (17,593), were readmitted for AMI (25,185), were admitted by
interhospital transfer (42,277), had a terminal illness or metastatic cancer (4,616), were
hospitalized outside the United States (1,760), had unverified mortality (357), and were admitted
to hospitals for which American Hospital Associat ion (AHA) data were unavailable (2,363). We
also excluded patients admitted to hospitals surveyed by JCAHO for which data were not
available (14,598). In total, the study cohort comprised 134,579 patients.
* Quality of AMI care and outcomes. Quality of ca re for AMI was assessed using a set of
clinical performance measures from the Centers for Medicare and Medicaid Services (CMS) that
assess the use of therapies among patients (ideal candidates) who would benefit from and did not
have contraindications for particular treatments. We evaluated the following quality performance
measures: use of aspirin or beta -blockers within forty -eight hours of admission, aspirin or beta -
blockers anytime during hospitalization, and acute reperfusion therapy (thrombolytic agen ts or
primary angioplasty) within six hours of admission.11 We examined patient outcomes using
thirty -day mortality because the benefits of high -quality hospital care should be evident within
this period. Dates of death were obtained from the Medicare Enro llment Database and the Social
Security Administration's Master Beneficiary Record.
* Statistical analysis. Chi -square tests and analyses of variance were used to compare differences
across hospitals, and the Cochrane -Armitage test was used to evaluate fo r linear trends in therapy
or mortality rates associated with higher accreditation ranking. We compared hospitals' risk -
standardized thirty -day mortality rates using the Medicare Mortality Predictor System (MMPS),
a disease -specific mortality prediction mo del for elderly patients.12 Using logistic regression, we
calculated a risk -standardized mortality rate that estimated thirty -day mortality for hospitals in
each JCAHO accreditation group, assuming that they had the same patient characteristics as the
over all sample. Because of the correlation between hospital characteristics, physician
characteristics, and JCAHO accreditation, the primary analyses were risk -adjusted for patient
characteristics only; secondary analyses that added adjustment for hospital and physician
characteristics were also performed.
To assess the heterogeneity of hospitals' performance within JCAHO accreditation categories,
we calculated the observed use of AMI therapies in ideal patients and risk -standardized thirty -
day mortality for i ndividual hospitals. Standard deviations and twenty -fifth through seventy -fifth
percentiles were evaluated to determine variations within categories in AMI therapy use and thirty -day mortality rates within a particular JCAHO accreditation group. To ensure stability in
these estimates, we restricted our analyses to hospitals with at least twenty -five observations.
Statistical calculations were performed using STATA 7.0.
Study Results
The final study cohort consisted of 134,579 patients treated at 4,221 hos pitals. Approximately
one -quarter of hospitals in the study sample were not surveyed by JCAHO (Exhibit 1). Most of
the surveyed hospitals received accreditation with recommendations. Nonsurveyed hospitals
were more likely than surveyed hospitals were to be smaller -volume centers, nonteaching
hospitals, publicly owned, and located in a rural setting, and most lacked on -site facilities for
cardiac procedures. Surveyed hospitals with higher accreditation levels tended to be larger --
volume teaching centers and to be located in urban settings with on -site facilities for cardiac
procedures (Exhibit 1).
On average, patients in our cohort were elderly (mean age, seventy -six years) and predominantly
white (90.9 percent). Although several patient characteristics dif fered across JCAHO
accreditation levels, the magnitude of these differences was small (Exhibit 2).
* AMI therapy use. The proportion of patients who were classified as ideal candidates for AMI
therapy was generally similar across JCAHO hospital accreditat ion levels and between surveyed
and nonsurveyed hospitals (Exhibit 3). Patients admitted to nonsurveyed hospitals were less
likely to receive aspirin and beta -blockers, both on admission and during hospitalization, as well
as acute reperfusion therapy, tha n were patients treated at surveyed hospitals. Among surveyed
hospitals, the use of aspirin on admission was highest in hospitals accredited with
recommendations and lowest in hospitals with conditional accreditation (Exhibit 3). Aspirin use
at any time du ring hospitalization was similar across accreditation categories. Patients admitted
to hospitals accredited with commendation had the highest use of betablockers on admission and
at any time during hospitalization, while patients admitted to hospitals with conditional
accreditation had the lowest use. Acute reperfusion therapy rates were lowest among patients
admitted to conditionally accredited hospitals. These findings were consistent in secondary
analyses that adjusted for hospital and physician characte ristics.
Exhibit 4 illustrates the wide heterogeneity in performance within each JCAHO accreditation
level. There was considerable overlap in the proportion of patients receiving aspirin or beta -
blockers by hospital accreditation categories. The extensive overlap demonstrates that many
hospitals accredited with commendation had rates of aspirin and beta -blocker use that were
comparable to, and in some cases lower than, those of hospitals that had received conditional
accreditation or nonsurveyed hospitals, and vice versa.
* Mortality. Hospitals accredited with commendation had lower thirty -day mortality rates than
the overall risk -standardized rate; nonsurveyed hospitals had rates that were higher (Exhibit 3).
Compared with hospitals accredited with commen dation, thirty -day mortality was higher on
average for accredited hospitals (hazard ratio [HR] 1.15, p = .01) and hospitals accredited with
recommendations (HR 1.06, p <.01). There was a trend toward higher mortality among
conditionally accredited hospital s (HR 1.11, p = .39). Further adjustment for hospital and physician characteristics attenuated the relative hazard rates, but the results were consistent with
those from the primary analysis (accredited hospitals HR 1.11, p = .05; accredited with
recommend ations HR 1.05, p = .02; conditional accreditation HR 1.03, p = 0.80; accredited with
commendation HR 1.00 [referent]).
Nonsurveyed hospitals had higher thirty -day mortality rates than surveyed hospitals had (HR
1.15, p < .001) when patient characteristic s were adjusted for. The increased hazard associated
with nonsurveyed hospitals was attenuated after adjustment for hospital and physician
characteristics, but remained significant (HR 1.08, p <.001).
However, we found considerable variation in risk -stand ardized thirty -day mortality rates within
each accreditation level (Exhibit 4). The interquartile ranges of risk -standardized thirty -day
mortality were primarily located between 15 percent and 25 percent across all accreditation
levels.
Discussion
In our study, nonsurveyed hospitals had lower use of AMI therapies and worse thirty -day
outcomes than did hospitals surveyed by JCAHO. However, among surveyed hospitals there
were only modest differences in the use of AMI therapies, with the greatest variation o bserved
for the use of beta -blockers. Patients admitted to hospitals accredited with commendation had
lower thirty -day mortality rates than those of patients admitted to hospitals in lower accreditation
levels. However, we observed much variation in qualit y measures and outcomes within each
JCAHO accreditation category across hospitals.
These findings suggest that the JCAHO standards -based accreditation system has only a modest
ability to assess quality of AMI clinical care at any particular hospital. Accr editation does
provide some information concerning hospitals' quality of care and outcomes in the aggregate.
Indeed, knowing that a hospital participated in the JCAHO survey process suggests superior
quality and outcomes compared with nonsurveyed hospitals . It is unknown, however, whether
the process of undergoing JCAHO accreditation improves quality of care or whether this
association reflects self -selection against JCAHO evaluation by more poorly performing
hospitals.
In contrast, accreditation levels we re of limited value in differentiating quality among surveyed
hospitals. Although beta -blocker use was higher across successive accreditation levels, the
absolute differences in rates across accreditation groups were small. Furthermore, there was
considera ble hospital -level variation in the use of aspirin therapy, the use of beta -blocker
therapy, and thirty -day mortality rates within all JCAHO accreditation groups. There were
hospitals with high and low rates of AMI therapy use and thirty -day outcomes in al l JCAHO
accreditation categories, even among hospitals with JCAHO conditional accreditation and non -
surveyed hospitals. Thus, a higher JCAHO accreditation level was not necessarily a guarantee of
higher -quality care or better outcomes in the management of AMI.
To place the mortality difference across accreditation categories in perspective, the relative
difference in risk for thirty -day mortality between surveyed and non -- surveyed hospitals was approximately 15 percent. In contrast, an examination of hosp ital volume and AMI mortality in
the CCP data set identified a 17 percent relative risk difference in thirty -day mortality between
the smallest and largest hospital volume quartiles.13 Accreditations ability to predict short -term
mortality after AMI appear s comparable to that of hospital volume.
* Reasons for lack of quality differentiation. There are several reasons why standards -based
JCAHO accreditation levels may not be able to differentiate hospitals on the basis of quality.
First, many of the JCAHO s tandards do not assess quality in day -to-day patient care activities.
For example, a high degree of compliance with administrative or managerial standards is
unlikely to have much bearing on whether patients receive aspirin on admission for AMI, yet
these areas account for more than half of all points in a JCAHO survey. Identifying hospitals that
are well managed, while informative, is likely to be different than identifying hospitals that
provide high -quality clinical care.
Second, the wide range of hospi tal compliance with JCAHO standards within a single
accreditation level may dilute any differences in quality. For example, the category of
"accredited with type I recommendations" does not distinguish between hospitals with a single
recommendation or many . Similarly, hospitals are assigned conditional accreditation whether
they received one citation or several.
Third, JCAHO surveyors exhibit discretion when determining how deeply to probe for potential
problems during a survey visit.14 The impact of varia tion by and between observers and the
reliability of the JCAHO accreditation process are unknown. The Joint Commission itself has
recognized that levels of accreditation can be subjective. Commenting on the recent removal of
the accreditation with commenda tion rating, JCAHO president Dennis O'Leary stated that "the
distinction between those who get commendation and those who fall just short is artificial in
many respects."15
* JCAHO as an accreditor of quality. Given that JCAHO accreditation cannot differe ntiate
hospitals on the basis of clinical performance, the question is whether JCAHO would be an
effective force for assessing and improving quality There would be several potential advantages
for having JCAHO evaluate quality in addition to its current st andards -based accreditation.
First,JCAHO has the administrative machinery necessary to evaluate hospitals. Thus, there are
financial and logistical benefits to having it evaluate both standards and quality. Second, JCAHO
accreditation is sought nearly uni versally; as a result, the effect of codifying quality into
accreditation decisions would be readily disseminated across the country. Third, as the nation's
most widely accepted accreditor, JCAHO would likely meet with less resistance from hospitals
to the inclusion of quality measures as a natural extension of the accreditation process rather than
an entirely new review process.
In spite of the advantages, several challenges remain. First, although JCAHO is an independent
institution, it has close ties to the industry it oversees. In a recent critique, the Office of Inspector
General of the Department of Health and Human Services reported that JCAHO's stance is
"moving towards collegiality rather than regulatory," suggesting a lack of impartiality in
evalu ating hospitals.16 Similar concerns have been raised by public -interest groups, which note that half of the members of JCAHO's board of commissioners are from within the industry it is
supposed to regulate (the American Hospital Association and the America n Medical
Association).17
Second, while JCAHO has indicated a willingness to incorporate quality into accreditation
decisions, the specific details are lacking. It is less likely that hospitals will feel an incentive to
improve quality if their accreditat ion is not placed at risk. However, critics contend that very few
hospitals are denied accreditation.18 Whether placing accreditation in jeopardy on the basis of
quality will lead to quality improvement remains to be seen.
Third, JCAHO's current system fo r quality measurement is limited. To its credit, JCAHO has
recognized that standards and performance measurement are complementary to assessment of
hospital care and has embarked upon a program to integrate clinical performance measures into
accreditation decisions.19 In the mid -1990s JCAHO began requiring accredited hospitals to
submit performance data through its "Oryx initiative." Hospitals contracted with vendors to
collect data and developed automated databases that feed performance measures back to
ho spitals and JCAHO each quarter.
However, the Oryx methodology raises questions regarding its validity for measuring quality.
Hospitals could select any six of more than 2,000 performance measures. This is problematic
because of the potential for hospitals to "game the system" by selecting measures at which they
already do well. Also, there is wide variation in clinical importance in the performance measures,
which range from length -of-stay, mortality or readmission rates, use of procedures such as
cesarean section, patient fall rates, or use of restraints. There is no guarantee that a particular
hospital -chosen performance measure represents meaningful differences in quality. Finally,
hospitals are evaluated against peers, but the comparison groups are diff erent for each vendor's
system. The benchmark group could range from hospitals that used the same vendor's measure,
or it may include nonvendor data from the CMS or state health departments, all of which limit
Oryx's ability to determine national benchmark s for quality.
To mitigate these limitations, JCAHO recently began requiring hospitals to report a set of -core
performance measures" from among four medical conditions (AMI, heart failure, community -
acquired pneumonia, and pregnancy) with specific defini tions for numerators and
denominators.20 The advantages of using these core measures is that the clinical consensus
underlying the quality indicators ensures that they can be compared across both hospitals and
time. It is too early to tell whether the repo rting of these core measures will affect hospital
accreditation or lead to improvements in patient care and outcomes.
* Additional elements of success. Besides selecting appropriate performance measures,
establishing standardized benchmarks, and codifying the effects of quality on accreditation, we
believe that several additional key elements are necessary if accreditation is to have a substantial
and lasting public role for monitoring hospital quality.
Publication of quality measures. Public release of comparative hospital data will allow patients
and purchasers to make purchasing decisions based on quality. Consumers would "vote with
their feet" in selecting health plans incorporating hospitals that emphasize quality. Purchasers could contract for care based on quality and thereby receive greater value for their health care
dollars. Moreover, providers could use explicit measures of quality when negotiating contracts,
rather than relying on subjective measures or purchasers' perception s of quality.
Rewards for success. Purchasers' decisions to contract on the basis of quality need not be
punitive. The Pacific Business Group on Health (PBGH) has negotiated with several health plans
in California to place $8 million at risk for meeting p erformance measures on patient
satisfaction, preventive care measures, and cesarean section rates.21 In addition, the Leapfrog
Group has embarked on a program to reward hospitals for meeting requirements for hospital
safety, evidence -based hospital referra l, and physician staffing in intensive care units.22 These
examples demonstrate that purchasers are amenable to pursuing reimbursement that rewards
superior quality.
Influence of government. The federal government is uniquely positioned to motivate change s in
JCAHO accreditation because of accreditations role in securing hospitals' Medicare
reimbursement. This criterion could be leveraged to improve the quality of care for the elderly by
having Medicare pay more (or less) depending on providers' quality me asures for diseases
prevalent in the elderly; by providing a highly visible distinction for hospitals that achieve high
standards of performance; or even by tying participation in Medicare to minimum quality -of -care
standards.
OUR STUDY SUGGESTS that an e xclusively standards -based accreditation is a limited tool for
comparing hospital quality of care, because of the considerable heterogeneity of performance
within accreditation levels across hospitals; this highlights the need to measure and report quality
indicators directly. The integration of standardized quality measures into the next generation of
JCAHO accreditation may address this deficiency. Nevertheless, there are major challenges for
JCAHO, as it ponders how to integrate quality into its accredit ation process.
