Avascular necrosis significantly impairs quality of life in sickle cell disease

Quality of life (QoL) assessment has become an integral component of the assessment of the holistic care of patients with chronic diseases, including sickle cell disease (SCD). Objective: To evaluate the quality of life in patients with SCD managed in our centre. Patients and Methods: Eighty consecutive patients with confirmed hemoglobin SS or SC were recruited. Age and sex-matched volunteers served as controls. Ethical approval was obtained from the Institutional Review Board and all participants gave informed consent. Information on socio-demographic, quality of life and clinical variables, including the presence of complications were recorded in a modified version of the WHO Quality of Life Brief version (WHOQOL-BREF) questionnaire. Data was analyzed using Microsoft Excel and SPSS 17 computer softwares. Descriptive statistics were used to represent socio-demographic variables while the Student t-test was used to explore relationship between the variables and the quality of life domains. Results: Significantly fewer participants with SCD are married compared to their age- and sex-matched controls (P = 0.01). Similarly, participants with SCD scored significantly lower in the physical and psychological domains as well as in overall QoL and general health domains compared to controls (P = 0.001). Avascular necrosis of the femur significantly affected the overall QoL and general health of participants with SCD, respectively while the means of the QoL assessment domains were not significantly different in participants with SCD with and without complications, except in the general health domain (P < 0.001). Conclusion: Avascular necrosis of the femoral head significantly affects overall QoL in participants with SCD
