Background: Pharmacy departments in large acute hospitals play a crucial role in ensuring timely and efficient medication delivery to patients. The evolution of clinical pharmacy in the UK over the past three decades has emphasized the importance of pharmacists in optimizing drug therapy outcomes and patient care. However, the practice of clinical pharmacy varies across hospitals, leading to inconsistencies in service delivery and patient benefits. The concept of pharmaceutical care has emerged as a patient-centered approach to pharmacy practice, focusing on achieving specific therapeutic outcomes to improve patient quality of life. Despite the adoption of pharmaceutical care principles in the UK, challenges such as service diversity, lack of central direction, and limited dissemination of service improvements persist in hospital pharmacy settings. Objective: This review aims to evaluate the impact of clinical pharmacy services on patient outcomes in hospital settings, assess the effectiveness of pharmacist interventions in enhancing medication safety and adherence, explore the role of clinical pharmacists in multidisciplinary healthcare teams, investigate challenges faced by clinical pharmacists in delivering optimal pharmaceutical care, and identify opportunities for expanding and enhancing clinical pharmacy services to meet evolving patient and healthcare provider needs. Conclusion: The research article underscores the importance of advancing pharmaceutical care in hospital settings through evidence-based practices and consistent service delivery. Challenges such as pharmacist recruitment and the need for enhanced research in pharmacy practice in secondary care are highlighted. Recommendations include strengthening interprofessional collaboration, developing frameworks for integrated pharmaceutical care, and focusing on patient-centered outcomes to drive advancements in pharmacy practice. Overall, the article emphasizes the significance of systematic and evidence-based approaches to meet the evolving needs of patients and healthcare providers in clinical pharmacy services.
