Summary

Sickle cell disease (SCD) is associated with a lifetime of medical and socio-behavioural complications that require coordination of care from multidisciplinary teams. Access to adequate care for SCD is important as inadequate access can contribute to increased acute care utilization, disjointed care delivery, and earlier mortality for many SCD patients. Hydroxyurea (HU) is the first drug approved for the treatment of SCD and improves many adverse outcomes of SCD and yet its use remains sub-optimal. This mixed-methods study aims to identify the barriers and enablers that SCD patients, caregivers of children (under age 18 years), and health care providers (including physicians, nurses and pharmacists) identify for health care access and HU utilization. The findings may guide development and implementation of strategies to improve access to SCD healthcare and HU uptake which may result in significant benefits to patients, families and the healthcare system including possible reduction in healthcare utilization. Participants will be recruited from the Sickle Cell Unit, Kingston and from all four Jamaican regional health authorities. Questionnaires and interview guides for provider and patient/caregiver assessments are adapted, with permission, from the Sickle Cell Disease Implementation Consortium tools. The study will also examine data on HU usage from the National Health Fund of Jamaica since its addition of SCD to its list of chronic illnesses in 2015. All data collected will be de-identified and maintained in a secure database, with access limited to key personnel. There is minimal risk to participants. Participants will be selected only because of the specific problem under investigation, and not because of easy availability, diminished autonomy, or social bias.
