Patient satisfaction is of great importance and is a key factor in the quality of care. The most commonly used measure of this factor is satisfaction surveys. This study used the modified SERVQHOS healthcare quality survey model, which adapts the SERVQUAL survey. The main objective was to determine the degree of satisfaction of patients seen in the outpatient department of the Dermatology Service, as well as to describe and detect those aspects that could be improved to offer better quality care. A total of 250 patients responded to the survey. The mean Likert scale score for the 19 items on the perceived quality of care was 4.17 ± 0.796 points. Up to 92.8% were satisfied or very satisfied with the care received. All items were statistically correlated with overall satisfaction (p < 0.001). In the multivariate study, the variables with predictive capacity in relation to overall satisfaction (p < 0.05) were “the technology of the medical equipment”; “the directions to the consultation”; “the confidence that the staff transmits”; “the state of the consultation”; and “the interest of the staff in solving problems”. Satisfaction was significantly higher in men (p < 0.05), with a level of education up to primary school (p < 0.05) and no work activity (p < 0.001). The final mean score in the degree of perceived satisfaction was very high, indicating that the expectations of the patients were exceeded, and showing that satisfaction is closely linked to the qualities and skills of the staff in their relationship with the patient.
