Phenomenology has emerged as a pivotal qualitative research approach in nursing, offering a profound lens for exploring individuals lived experiences in relation to health, illness, and care. Rooted in the philosophical traditions of Edmund Husserl and Martin Heidegger, phenomenology seeks to uncover the essence and meaning of human experiences, thereby enriching the epistemological foundations of nursing practice. This study employed an integrative review design, systematically organizing and synthesizing scholarly literature on phenomenology in nursing research. Relevant articles were analyzed and structured using the IMRAD framework to ensure methodological coherence and analytical rigor. The review encompassed both descriptive (Husserlian) and interpretive (Heideggerian) phenomenological approaches, highlighting their theoretical underpinnings and practical applications. Findings revealed that phenomenology is extensively utilized in nursing to elucidate patients lived experiences, healthcare providers’ perspectives, and complex care dynamics. The descriptive approach emphasizes bracketing and the identification of essential structures of experience, while the interpretive approach focuses on contextual meaning-making. The method significantly contributes to deep, nuanced insights that inform person-centered and holistic care practices. However, challenges such as maintaining methodological rigor, mitigating researcher bias, and managing interpretive intricacies were consistently identified across studies. Phenomenology offers substantial value in advancing nursing knowledge by fostering empathy, reflective practice, and evidence-based care grounded in human experience. Despite its methodological challenges, its capacity to illuminate the subjective realities of individuals underscores its indispensability in contemporary nursing research and practice.
