Impact of an oncohematologic pharmaceutical care model on patient experience: An observational study based on PREMs

Introduction Healthcare quality is increasingly assessed through patient-centered metrics, with Patient-Reported Experience Measures (PREMs) emerging as essential tools to evaluate the effectiveness of care models beyond clinical outcomes. In oncohematology, where treatments are prolonged and emotionally demanding, patient experience plays a critical role in therapeutic adherence and perceived safety. Methods This cross-sectional study was conducted at Sagunto University Hospital and included 90 patients undergoing active oncohematologic treatment. The impact of the Oncohematologic Pharmaceutical Care (OH-PC) consultation—a differentiated model integrating clinical pharmacists into direct patient care—was evaluated using a 16-item Likert survey based on validated instruments aligned with IEXPAC domains. Results The OH-PC model showed significant improvements compared to the traditional medication dispensing approach. Patients reported enhanced accessibility, better quality of information, and stronger professional-patient relationships. Notably, 100% of respondents stated they received clear explanations about their treatment, and over 94% expressed high satisfaction. The model positively impacted all IEXPAC domains: productive interactions (98.2%), self-management (95.1%), and relational model (90.0%). Conclusions The OH-PC consultation significantly improved patient-reported experience in oncohematologic care. These findings highlight the pivotal role of pharmacists in enhancing patient-centered care and suggest that the OH-PC model could be scalable to other chronic and complex care settings. The integration of PREMs is recommended for continuous quality improvement and healthcare system transformation.
