title: Designing an intervention to improve the management of Helicobacter pylori infection.
abstract: BACKGROUND
  An intervention to improve the testing and treatment of Helicobacter pylori (HP) in patients receiving chronic acid suppression (AS) therapy was developed at Harvard Pilgrim Health Care (HPHC), a mixed-model not-for-profit health maintenance organization.
  
  
  METHODS
  Ten full-time primary care physicians (4 staff model and 6 group practice) were interviewed in 1999 about their knowledge, attitudes, and practice regarding dyspepsia, the use of chronic AS drugs, and approaches to HP infection, as well as about the feasibility and acceptability of various potential interventions that might be used in a quality improvement program.
  
  
  RESULTS
  Self-reported practice regarding dyspepsia and HP infection were relatively uniform, and physicians were generally aware of current recommendations. Three common misperceptions acted as barriers to optimal HP management: Untreated HP was not considered an important problem; patients who used drugs for chronic AS rarely had HP infection; and chronic use of AS drugs was considered effective and without adverse consequence. All physicians wanted brief educational materials with explicit guidelines, preferably locally adapted and endorsed by local experts. All informants agreed that the main barrier to successful QI interventions was the requirement for any extra time or effort, particularly when directed at populations of patients who do not have symptomatic complaints.
  
  
  CONCLUSIONS
  The interviews revealed the many barriers to improving the management of HP infection and to targeting educational messages and tailoring different methods for facilitating practice change across different managed care settings. Evidence-based components of the intervention program include physician education, a notification/reminder system, and practice-based tools to facilitate change and minimize workload.
