The architectural design of healthcare institutions impacts patient experience and health outcomes. Facing challenges like demographic aging and evolving treatments, this study reviewed fourteen key publications on healthcare architecture. The insights gained have highlighted the need for qualitative methods to understand these environments. An integrated healthcare architecture framework (IHAF) was developed, integrating architectural guidelines, user experience, and sustainability. The IHAF emphasizes inclusive design, adaptability, patient-centricity, and staff well-being, focusing on eco-friendly practices and green spaces in healthcare facilities. Advocating a multidisciplinary design approach, the IHAF aims to create functional, sustainable, patient-focused environments. This research identifies the need for qualitative methods unique to the Slovenian healthcare context. It aims to inform architectural solutions for healthcare institutions, highlighting the role of design in optimal patient care and well-being.
