THE IMPACT OF CLINICAL PHARMACIST INTERVENTIONS ON HOSPITALIZED PATIENT SAFETY

Abstract

Patient safety is a fundamental pillar of healthcare quality in hospitals, particularly in view of the risks associated with medication use. In this context, the clinical pharmacist plays an important role in identifying drug therapy-related problems and strengthening safety practices. This study aimed to describe clinical pharmacist interventions related to the safety of hospitalized patients, identifying their main activities, their contribution to medication error prevention, and their role within the multidisciplinary healthcare team. This is a descriptive literature review with a qualitative approach, conducted using the SciELO, LILACS, Virtual Health Library (VHL), and PubMed databases between February and March 2026, considering articles published from 2016 to March 2026. The findings indicated that the interventions described included prescription review, medication reconciliation, identification of drug interactions, pharmacotherapy monitoring, and recognition of potential drug-related problems. The studies also indicated contributions to the identification of medication errors and the improvement of care processes, although the heterogeneity of methods and healthcare settings limits the generalizability of the results. It is concluded that clinical pharmacist practice is a relevant strategy for improving medication safety practices in hospital settings. Further studies are needed to assess its effects on patients' clinical outcomes.
