Group 2 studies
We found no study conducted in adult populations reporting the
proportion of hospital admissions prolonged by ADRs. Two paediatric
studies, one from Nigeria36 and one from South
Africa53 reported this proportion (Table 4). In the
Nigerian study36 0.29% children experienced
ADR-related prolongation of their hospital admission. ADR
preventability, presentations, implicated drugs, and HIV exposure were
not reported. In the South African study53 0.99%
admissions were prolonged by ADRs. Most prolongations were for
antibiotic-associated diarrhoea, although a variety of other
admission-prolonging ADRs occurred, including ADRs attributed to
corticosteroids and immunosuppressants. Only one study reported the
proportion of admissions prolonged by preventable ADRs, being 2/1106
(0.19%)53. Only one study, conducted in South Africa,
reported HIV prevalence among children whose hospital stays were
prolonged by ADRs, being 18%.53
