Background:
A 1-year prospective study of 545 patients with dyspepsia examined the natural history of dyspepsia in a primary care population. Predictors of gastrointestinal bleeding and other related utilization-of-service indicators were identified.
Methods:
Subjects were adult primary care patients seen at a southern California county medical center. Data were collected by means of a patient questionnaire as well as from medical charts and a computerized hospital billing system. Chi-square, t test, and stepwise multiple logistic regression analyses were used to analyze the data. Outcome events were follow-up visits for any gastrointestinal event and follow-up visits for gastrointestinal bleeding specifically.
Results:
Prior exposure to nonsteroidal anti-inflammatory drugs doubled the odds for any follow-up gastrointestinal event (odds ratio = 1.9; 95% CI = 1.4 to 2.8). Nonsteroidal anti-inflammatory drugs increased the risk for gastrointestinal bleeding by a factor of 7 (odds ratio = 7.1; 95% CI = 1.3 to 50.0).
Conclusions:
In a cohort of primary care patients with dyspepsia, use of nonsteroidal anti-inflammatory drugs was the most important predictor of a follow-up gastrointestinal event, both for any gastrointestinal event and gastrointestinal bleeding specifically.
