Is there an overprescription of proton pump inhibitors in oncohematologic patients undergoing ambulatory oncospecific treatment?

Objective: The aim of this study is to evaluate the prevalence of proton pump inhibitors (PPIs) prescription, and the level of adequacy of the indication of these drugs in oncohematologic patients under ambulatory oncoespecific treatment. Method: An observational descriptive study in oncohematologic patients under ambulatory oncoespecific treatment. A protocol for the rational use of PPI targeted to oncohematologic patients based on the PPI protocol of our hospital was designed. Patients under active treatment with PPIs were quantified and the appropriateness of their indications evaluated. Results: 111 patients (71 oncologic and 40 hematologic) were included. 56% of all oncologic patients and 63% of all hematologic patients were under active treatment with PPIs. After reviewing the indications for PPI in all patients, 72% of oncologic and 12% of hematologic patients did not present evidence justifying treatment with these drugs. Conclusion: It is important the pharmacist to detect unappropriated prescriptions of PPIs, especially among oncologic patients, and to promote a deprescription of these drugs
