This study analyzes the effect of patient clothes on hospital satisfaction. We conducted a survey on 272 patients from June 12 to August 14 in 2009. For the statistical analysis of data, t-test, ANOVA, and hierarchical regression analysis were used. The results of the study were as follows. First, the clothing satisfaction of patients depended on age and gender. Elderly patients were more satisfied with patient clothes compared to younger patients and patients with low educational backgrounds were more satisfied with patient clothes. Second, the effect of patient clothes on hospital satisfaction was statistically significant even after controlling for other factors. Third, the effect of patient clothes on hospital satisfaction depended on the age of the patient. In the case of young patients, the hospital satisfaction level increased sharply when they were satisfied with patient clothes.
