Helicobacter pylori test-and-treat intervention compared to usual care in primary care patients with suspected peptic ulcer disease in the United States.

Abstract

[corrected] The Helicobacter pylori (H. pylori) "test-and-treat" strategy in uninvestigated dyspepsia is an effective alternative to prompt endoscopy. Our aims were to determine whether the combination of an educational session and availability of office-based H. pylori testing (test-and-treat intervention [TTI]) increases use of the test-and-treat strategy by primary care practitioners and whether it improves patient outcomes. We conducted a 1-yr prospective trial of patients with suspected peptic ulcer disease in six primary care centers, three with TTI and three designated as usual care controls (UCC). H. pylori testing was performed in 81% of 54 TTI patients and in 49% of 39 UCC patients (p = 0.004). TTI and UCC patients had similar gastroenterology referral rates (24% vs 33%, p = 0.33), endoscopy or upper GI radiography rates (30% vs 31%, p = 0.91), and primary care visits per patient (3.1 +/- 2.8 vs 3.1 +/- 2.6, p = 0.92). TTI patients were less likely than UCC patients to receive repeated antisecretory medication prescriptions (35% vs 66%, p = 0.003). Symptomatic status at 1 yr and satisfaction with medical care did not differ between groups. Median (and interquartile range) annualized disease-related expenditures per patient were $454 ($162-932) for TTI and $576 ($327-1,435) for UCC patients (p = 0.17). The combination of an educational session and availability of office-based H. pylori testing may increase acceptance of the test-and-treat strategy by primary care providers. It remains to be determined whether increased use of the test-and-treat strategy yields significant improvements in clinical and economic outcomes compared to usual care.
