This study aimed to analyze the domestic studies on Integrated Nursing Care Services (INCS) to confirm research trends and present future directions. Methods: This study used the scoping review method, which comprises six stages: 1) identifying the research question, 2) identifying relevant studies, 3) study selection, 4) charting the data, 5) collating, summarizing, and reporting results, 6) consultation. Results: Studies related to INCS were multiplying and could be categorized into five themes: patient experience, risks to patient, nursing experience, risks to nurse, and environment of INCS unit. Research has primarily focused on investigating the phenomenon, with nurses as the predominant subjects. Although various variables were investigated for nurses, the results were controversial. Research on patients' experiences and risks is insufficient, and research variables are limited. Conclusion: Further research is needed on INCS regarding patients and environments. Research on nurses also requires repeated studies after controlling for various situations.
