Summary

A new policy encouraging histamine-type 2 receptor antagonist (H2RA) use before proton pump inhibitor (PPI) therapy showed a modest 9% increase in compliance. Careful consideration of costs and benefits is recommended for future interventions.

Area of Science:

  • Pharmacology and Therapeutics
  • Health Policy and Management
  • Gastroenterology

Background:

  • Proton pump inhibitors (PPIs) are widely used for acid-related disorders.
  • A step-up approach recommending histamine-type 2 receptor antagonist (H2RA) therapy before PPI initiation was implemented in Ontario.
  • Assessing compliance with this policy is crucial for optimizing gastrointestinal medication use.

Purpose of the Study:

  • To evaluate adherence to a step-up strategy for PPI therapy.
  • To determine the impact of a new provincial policy promoting H2RA use prior to PPI initiation.
  • To analyze prescribing patterns in a large, elderly population.

Main Methods:

  • Population-based, retrospective, open cohort study.
  • Utilized health administrative databases from Ontario, Canada.

  • Included approximately 1.4 million residents aged over 65 years.

    • Main Results:

    • In 1996, 73% of patients had a trial of H2RAs or gastrointestinal diagnostic testing before PPI therapy.
    • Following policy implementation (Jan-Apr 1999), 72% of patients received a trial of H2RAs within 12 months prior to PPI initiation.
    • A modest 9% increase in compliance with the H2RA step-up approach was observed.

    Conclusions:

    • The provincial policy resulted in a modest improvement in H2RA use before PPI therapy.
    • The study highlights the importance of evaluating the effectiveness of health policies.
    • Future interventions require careful consideration of their costs and benefits.
