Purpose: This study aims to not only understand the meaning and essence of patients’experiences visiting the Raphael Nanum Homeless Clinic but also explore what kind of healthcare programs they would like to have in the future by appraising patients’experiences in depth. Methods: This study employed a qualitative content analysis method. The data were collected from June 11, 2023, to June 25, 2023. A total of 17 patients who could provide detailed experiences of their visit to the Raphael Nanum homeless clinic participated in this study. We conducted a focus group interview with 6 patients and in-depth one-on-one interviews with the remaining 11 patients. Results: The qualitative content analysis result revealed five themes: “visiting a free clinic for various paths,” “positive experiences at the free clinic,” “negative experiences at the free clinic,” “dissatisfaction with the clinic site,” and “anticipation for the future of the free clinic.” Conclusion: To ensure the right to health and survival of marginalized populations in the future, it is necessary to establish comprehensive healthcare support measures, which include enhancing the facilities of the free clinic and expanding the range of available medical specialties.
