HOSPITAL PHARMACY SERVICES AND PATIENT SAFETY: CURRENT PRACTICES, CHALLENGES, AND FUTURE DIRECTIONS

Abstract

Patient safety remains a fundamental component of healthcare quality, with medication-related harm representing one of the most significant preventable causes of morbidity and mortality worldwide. Hospital pharmacy services have evolved substantially from traditional medication dispensing functions to comprehensive clinical and patient-centered services that contribute directly to medication safety and therapeutic outcomes. The increasing complexity of healthcare systems, rising prevalence of chronic diseases, polypharmacy, and the introduction of high-risk medications have amplified the need for robust hospital pharmacy services. This review examines the current scope of hospital pharmacy services and their impact on patient safety across various stages of the medication-use process. Key services include medication procurement and distribution, clinical pharmacy interventions, medication reconciliation, antimicrobial stewardship, therapeutic drug monitoring, pharmacovigilance, patient counseling, and participation in multidisciplinary care teams. Evidence demonstrates that pharmacist-led interventions significantly reduce medication errors, adverse drug events, hospital readmissions, and healthcare costs while improving treatment outcomes and patient satisfaction. The review also explores emerging technologies, including computerized physician order entry systems, barcode medication administration, automated dispensing cabinets, clinical decision support systems, artificial intelligence, and telepharmacy, which are reshaping hospital pharmacy practice. Despite these advances, challenges such as workforce shortages, limited reimbursement mechanisms, inadequate integration of pharmacists into clinical teams, technological barriers, and regulatory constraints continue to hinder optimal service delivery. Future directions should focus on strengthening interprofessional collaboration, expanding pharmacists' clinical responsibilities, integrating digital health technologies, and establishing supportive policies to enhance medication safety and patient-centered care.
