This study was conducted to analyze the concept of nurse dose using a hybrid model. The approach included theoretical, field work, and final analysis stages. For the theoretical stage, we searched Ovid-Medline, CINAHL, PubMed and KoreaMed, the National Library of KOREA, the National Assembly Library, NDSL, KISS and RISS databases for relevant articles. Of them, 40 documents were included in the final analysis. For the field work phase, in-depth interviews were conducted with four nursing managers. Six attributes of nurse doses were discovered, which were practical experience, degree of education, time spent in nursing the patient, interaction between patient and nurse, commitment to the organization and empathy. Nurse productivity was shown to be a concept covering nurse dose. Thus, this study confirmed the concept of nurse dose, which is ambiguous in clinical practice and can-not be properly evaluated. The conceptual analysis of nurse doses in the clinical nursing field will provide the basis for improvement in the quality of nursing, and it will contribute to the improvement of patients' satisfaction.
