The hidden financial burden of healthcare: a systematic literature review of informal payments in Sub-Saharan Africa

Despite being common, in-depth examination of informal charging practices in Sub-Saharan Africa is lacking. We therefore conducted a systematic literature review to synthesize evidence on the prevalence, characteristics, determinants, and impact of informal payments in SSA.

The materials provided include characteristics of studies included in the review and the search strategies used to identify relevant literature across various electronic databases.
