Sickle cell disease in southwestern Nigeria: assessment of knowledge of primary health care workers and available facilities

Background: Patients with sickle cell disease (SCD) benefit optimally from comprehensive care. In Nigeria, despite the huge burden, involvement of community health workers (CHWs) in the management of SCD is poor. Methods: This community-based study assessed SCD-related knowledge of 182 CHWs from the 46 primary health care (PHC) centres in Ilesa, southwestern Nigeria. Available facilities and management practices for SCD care at these centres were also evaluated using pretested self-administered questionnaires and observational checklists. Results: The majority of CHWs (167/182 [91.8%]) knew that SCD is an inheritable blood disorder. However, only 32.4% and 26.4% knew that SCD can be diagnosed in the prenatal and neonatal periods, respectively. Also 37.4%, 49.5% and 67.6% knew about the role of chemoprophylaxis (folic acid/penicillin), adequate fluids and malaria prevention, respectively, in SCD care. Overall, 37.9% had good knowledge on the nature and care of the disease. Just 2/46 (4.3%) PHC centres treat patients with SCD. SCD-targeted nutritional counselling and referral to secondary/tertiary hospitals were poor and unorganized. No centre offered SCD screening, home visits or recordkeeping. Conclusions: The Level of SCD care and knowledge of CHWs at PHC centres in southwestern Nigeria of early SCD diagnosis and crisis prevention is poor. CHWs should be regularly trained and equipped for basic SCD management, including early detection, crisis prevention, prompt referral and provision of basic genetic counselling, to dispel associated myths and stigma.
