[Frequency of proton pump inhibitor prescription based in clinical practice guidelines in hospitalized patients in two academic hospitals in Lima, Peru].

OBJECTIVES: To evaluate if Proton Pump Inhibitor (PPI) prescription is based in Clinical Practice Guidelines (CPG) in hospitalized patients at two academic hospitals of Lima.
MATERIALS AND METHODS: The services of Intern Medicine, Tropical Medicine and General Surgery were visited. Therapeutic sheets and nursing transcript were checked. The prescription motifs were determined in patients who received PPI. These motifs were obtained according to a check list, which was made from different CPG.
RESULTS: 54.57% of the PPI prescriptions in the two academic hospitals were not based in CPG. No statistic significant difference was found between the two academic hospitals in the PPI prescription based in CPG (p=0,208). Most of the prescriptions not base on CPG belong to the service of General Surgery (83.6%; p<0.0001). The main indication for the prescription of PPI based on CPG was prevention of NSAIDS induced gastric ulcers if advanced age (65.72%).
CONCLUSIONS: There is a high rate of PPI overuse in two academic hospitals.
