ABSTRACT
The aim of this study was to evaluate the physician's perception of pain experienced by patients with sickle-cell disease (SCD). Pain experiences reported by patients were compared with physicians' perception of the patient's pain, and the treatment decision-making process was evaluated. Fifty-two patient-physician pairs were assessed. Before the clinic visit, the patients completed a 3-item on pain experienced 24 h prior to the visit and the PHQ-9. After the patient visit, the physicians completed a questionnaire assessing their perception of the patient's pain and a questionnaire on the factors taken into consideration when evaluating the patient's pain experience. The physicians rated the patients' pain as more intense than did the patients themselves; and there was agreement between pain intensity measurements (p < 0.05). The physicians' perception was influenced by the pain intensity reported by the patient, results of blood count at the time of the patient visit, and medication availability in the public health services. However, these factors were not predictive of the patient's pain intensity perceived by the physician. Patients' depressive symptoms were not predictive factor of the physicians' perception. Biochemical, genetic and symptomatic characteristics of SCD influenced the physicians' perception of the patient's pain experience, while psychosocial aspects did not.

In several types of chronic pain, catastrophizing has been related to higher pain intensity, and health care utilization but it has not been explored extensively in sickle cell disease (SCD). The objective of the study was to identify the role of catastrophizing in SCD, specifically in relation to painful crises, non-crisis pain, and responses to pain. Two hundred and twenty SCD adults were enrolled in a prospective cohort study of pain and completed between 30 and 188 daily diaries in 6 months. The Catastrophizing subscale (CAT) of the Coping Strategy Questionnaire (CSQ) was administered at baseline and at study exit. Depression and quality of life were measured by the Patient Health Questionnaire and SF-36, respectively, at baseline. The CAT mean was 13.6 (SD=8.4) and higher CAT was correlated with greater depression severity (r=0.48; p<0.001) and poorer quality of life in all domains (r=-0.24 to -0.47; p<0.001). There was no significance difference between CAT mean baseline and exit scores, and the measures were strongly correlated within patients (r=0.69; p<0.001). No difference was found between higher and lower catastrophizers in intensity of pain, distress, interference, and health service utilization, both on crisis or non-crisis SCD-related pain days, after controlling for depression. Adults with SCD had a higher mean catastrophizing score than found in studies of other chronic pain conditions that are not lifelong and life-threatening. CAT scores were not correlated with pain parameters or utilization. The role of catastrophizing in other conditions cannot be generalized to SCD.
