Process of care and outcomes for elderly patients hospitalized with peptic ulcer disease: results from a quality improvement project.
BACKGROUND
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.


OBJECTIVE
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.


METHODS
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.


METHODS
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.
