Patient perceptions of a proton pump inhibitor therapeutic interchange program across the continuum of care.

Objective: To determine if participation in a hospital-based proton pump inhibitor (PPI) therapeutic interchange program resulted in differences in patient perceptions related to clinical and humanistic outcomes.

Methods: A quasiexperimental repeated-measures study compared patients' perceptions in two groups (111 patients) at hospital admission, discharge, 3-4 days after discharge, and 2-3 weeks after discharge to detect differences across the continuum of care. Patient awareness of the hospital-based interchange also was examined.
