[Perception and assessment of pain by caregiver and adolescent with sickle cell disease: The impact of the patient's anxiety]. / Perception et évaluation de la douleur par le soignant et l'adolescent drépanocytaire : impact de l'anxiété du patient.

Pain is the main symptom in sickle cell disease and is a major issue in its management. Its complexity often makes assessment difficult for both patients and caregivers. This study looks for a link between anxiety in children with sickle cell disease at the beginning of their hospital stay and the difficulties experienced by caregivers to assess their pain. Forty teenagers hospitalized for a vaso-occlusive crisis were included in this prospective study. To determine which patients were "difficult to assess," a self-assessment of pain combined with a nursing assessment were proposed to patients (NS [numerical scale] and FLACC [Face Legs Activity Cry Consolability]). Feedback from specialized physicians was collected. In this study, no objective criteria allowed us to determine whether patients were "difficult to assess." At the beginning of the hospital stay, self-assessment for pain and nurse assessment with the NS matched. In this context, the FLACC scale did not assist in determining the pain score accurately. Patients identified as difficult to assess by physicians are more anxious than others.
