... e mean self-care agency score was 101.70 AE 20.14, with 36 (35.3%) outpatients scoring high. Demographic variables did not significantly influence the self-care level. However, health knowledge was significantly correlated with self-care skills, indicating that knowledgeable outpatients were more likely to be better at self-care. Conclusions: Outpatients with external fixation support need higher levels of health knowledge. The level of self-care agency in the present study was in the moderate range. Outpatients with external fixation support with higher health knowledge are more likely to have higher selfcare skills.
