RESUMEN
Purpose: The study aimed to examine the effect of a child-friendly design on the pain and anxiety levels during blood draw in children aged 1-3 years and the satisfaction levels of their parents toward the environment in which they receive health care services. Methods: The nonrandomized study was conducted with 158 children aged 1-3 years and their parents. Data were obtained with the "Personal Information Form," "Face, Legs, Activity, Cry, Consolability (FLACC) Pain Scale," "Visual Analog Scale (VAS) Anxiety Scale," and "Parental Satisfaction Scale-VAS." Data were collected from the control group before the design and from the intervention group after the design. Results: During the blood draw, the VAS Anxiety score of the children in the intervention group was 3.17 ± 1.44 and that of the control group was 7.00 ± 2.51 (t = 246.500, p < .001). The FLACC score was 3.94 ± 1.65 in the intervention group and 7.32 ± 2.51 in the control group (t = 915.000, p < .001). The mean satisfaction scores of the parents in the intervention group for the environment where they received health care were 10.00 ± 0.00, and those of the parents in the control group were 4.85 ± 1.68 (test = -11.561, p < .001). Conclusion: The child-friendly design effectively reduced children's pain and anxiety levels during blood draws and increased parents' satisfaction with the environment in which health care was received. Practical Implications: Implementing a child-friendly design in blood collection units is recommended to alleviate the pain and anxiety associated with children's blood draws, thereby enhancing parental satisfaction with the care provided.
