Informal caregivers (ICs) are at the heart of Universal Health Coverage (UHC) as they supply valuable labour to the health system. However, they face significant challenges, which can be worsened by the circumstances under which they support patients on admission. This policy brief reported findings from a study on the lived experiences of ICs who travel to an urban tertiary health facility to support sick relatives. It identified why ICs stay in the hospital while supporting hospitalisation care, the consequences of their challenges, and outlined what must be done to alleviate their plight in Nigerian health facilities.
