Lansoprazole overutilization: methods for step-down therapy
Abstract
OBJECTIVE: To identify the documented indications for long-term therapy with lansoprazole 30 mg twice daily at the Veterans Affairs Pittsburgh Healthcare System, assess compliance with appropriate use criteria, evaluate patients eligible for step-down therapy, and recommend appropriate step-down therapy in order to improve patient care, decrease overprescribing, and reduce medication costs.
STUDY DESIGN: Prospective intervention.
METHODS: The records of all patients with prescriptions for lansoprazole 30 mg twice daily as of June 2000 were reviewed. Patients were interviewed to assess medication compliance and symptom control and to provide education on lifestyle modifications. Interventions with the providers were completed to encourage step-down therapy in appropriate patients.
RESULTS: Two hundred forty-eight patients with active prescriptions for twice-daily lansoprazole were reviewed. Of these patients, 66% (n = 163) did not have an indication compliant with the medical center's guidelines for use of lansoprazole 30 mg twice daily. Of these, 88% (n = 143) had no documented attempt at step-down therapy and 49% (n = 80) had no documented gastrointestinal workup. Interventions for step-down therapy were recommended for 48% (n = 120) of the 248 patients. Forty-six percent (n = 60) of recommendations were accepted, resulting in a cost savings of dollars 85000 per year.
CONCLUSIONS: A high rate of clinician noncompliance with the guidelines for appropriate use of lansoprazole…
How strong is the evidence?
Evidence Hub reads this as a cohort study, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 248 participants or records.
