Context
Since publication in 1994 of guidelines for management of peptic ulcer
disease (PUD), trends in physician practice and outcomes related to guideline
application have not been evaluated.Objectives
To describe changes in process of care that occurred in a quality improvement
program for patients hospitalized with PUD and to evaluate associations between
in-hospital treatment of PUD and 1-year rehospitalization for PUD and mortality
in a subset of these patients.Design, Setting, and Patients
Cohort study of 4292 sequential Medicare beneficiaries hospitalized
at acute care hospitals with a principal diagnosis of PUD in 5 states (Colorado,
Georgia, Connecticut, Oklahoma, and Virginia) in 1995 (baseline) and 1997
(remeasurement); outcomes were evaluated for 752 patients in Colorado.Main Outcome Measures
Changes in rates of screening for Helicobacter pylori infection, treatment for H pylori infection,
screening for nonsteroidal anti-inflammatory drug (NSAID) use, counseling
about NSAID use; outcomes included rehospitalization for PUD and all-cause
mortality within 1 year of discharge in Colorado.Results
Screening for H pylori infection increased
significantly (12%-19% increase; P<.001) in each
of the 5 states. Treatment of H pylori infection
increased in each state and was significantly increased for the entire group
of hospitalizations examined (8% increase overall; P
= .001). Despite increased screening, detection of H pylori infection was less frequent than expected in every state, (13%-24%)
and did not increase in any state. Screening for and counseling about NSAIDs
did not significantly increase overall or in any state. In the Colorado cohort,
the proportion of patients rehospitalized was unchanged in 1995 (8.9%) and
1997 (6.8%), and 124 patients (16%) in the combined 1995 and 1997 cohorts
died within 1 year. Treatment for H pylori was not
associated with a reduction in rehospitalization within 1 year (adjusted odds
ratio [OR], 1.24; 95% confidence interval [CI], 0.65-2.36) or with a reduction
in mortality (adjusted OR, 1.08; 95% CI, 0.68-1.71). Counseling about NSAID
use was associated with a decrease in risk of 1-year rehospitalization for
PUD (adjusted OR, 0.47; 95% CI, 0.22-0.99) and risk of all-cause mortality
(adjusted OR, 0.44; 95% CI, 0.26-0.75).Conclusions
This quality improvement program for elderly patients with PUD resulted
in increased screening for H pylori and increased
treatment of H pylori infection but no change in
counseling about NSAID use. However, with the low prevalence of H pylori detected, treatment of H pylori infection
was not associated with a reduction in repeat hospitalization for PUD or subsequent
mortality, whereas counseling about the risks of using NSAIDs was associated
with a reduction in the risk of both outcomes.
Figures in this Article
Peptic ulcer disease (PUD) is one of the most common disorders affecting
the gastrointestinal system, with a lifetime cumulative prevalence of 10%1 and a peak prevalence between ages 65 and 74 years.2 The costs of PUD, including the indirect costs of
lost work time and productivity, are estimated to be at least $8 billion per
year in the United States.3 In 1998, approximately
1.5% of all Medicare hospital costs were spent treating the consequences of
PUD.4
Infection with Helicobacter pylori is considered
to be the cause of 95% to 100% of duodenal ulcers and 70% to 90% of gastric
ulcers, and among persons without H pylori infection,
nonsteroidal anti-inflammatory drug (NSAID) use is assumed to be the major
cause.2,5 In the elderly, use
of NSAIDs is a contributing factor for up to 50% of ulcers and is associated
with increased rates of ulcer-related complications, such as perforation,
bleeding, and death.6- 9
In 1994, a National Institutes of Health (NIH) Consensus Development
Conference published recommendations for the management of PUD that reflect
the new understanding of the role of H pylori infection.5 The panel advised that all patients should be screened
for H pylori and that infection should be eradicated
whenever detected. The panel also recommended that all patients should be
evaluated for use of NSAIDs and that use of these drugs should be eliminated
whenever possible. Practice guidelines were subsequently published incorporating
these recommendations and also endorsing empirical treatment of H pylori infection in patients with duodenal ulcers because of the
strong association of infection with ulcers in this location.10
Although the efficacy of each intervention in the PUD guidelines has
been demonstrated in randomized controlled trials, the effectiveness of guideline
implementation to change clinically relevant health outcomes11- 12
in an unselected patient population has not been measured. Recommendations
to eradicate H pylori in PUD are based on randomized,
controlled clinical trials13- 17
that used endoscopic end points and, in many cases, excluded patients of advanced
age13,16- 17 or with
comorbidities15- 16 or NSAID use.14- 16 Recommendations to
eliminate NSAID use are based on extensive experience with these drugs in
patients with PUD, particularly in the elderly.2,8,18- 19
The 1994 NIH recommendations prompted quality improvement projects (QIPs)
within the Health Care Quality Improvement Program for Medicare beneficiaries
led by the Health Care Financing Administration (HCFA; now the Centers for
Medicare and Medicaid Services). Health Care Quality Improvement Program projects
are intended to improve practice by encouraging compliance with national guidelines.20
For this report, we obtained information from a peptic ulcer disease
QIP performed by 5 state peer review organizations: Colorado Foundation for
Medical Care, Connecticut Peer Review Organization, Georgia Medical Care Foundation,
Oklahoma Foundation for Medical Quality, and Virginia Health Quality Center.
The specific objectives of the QIP were to measure and improve the practice
of testing for and treating H pylori and to measure
and improve the practice of screening for and counseling about the risks of
NSAID use. Practice was measured in hospital cases from 1995 (baseline) and
in 1997 (remeasurement). Improvement was planned through data feedback vs
a focused continuing medical education program tested by a randomized controlled
trial (the results of this intervention evaluation will be published elsewhere).
The assessment of baseline practice patterns from 1995 has been previously
published.21
The patient population in this QIP is unselected, is older and sicker
than populations used in clinical trials,13- 17
and represents patients with PUD who consume the most resources, have the
highest rate of poor outcomes,2 and presumably
have the most to gain from effective treatment.
The purposes of this study were (1) to describe changes in management
of PUD in a cohort of Medicare patients during a multistate QIP and (2) to
explore associations between PUD management and rehospitalization for PUD
and all-cause mortality at 1 year after discharge for the index hospitalization
in the Colorado cohort.
