Data are n or ratio (95% CI). Country income level is based on the World Bank country income classification, 2018.
Suspected or confirmed infection.
Includes women who had an invasive procedure to treat the source of infection (vacuum aspiration, dilatation and curettage, wound debridement, drainage [incision, percutaneous, culdotomy], laparotomy and lavage, other surgery), admission to intensive care or high dependency unit, or transfer to another facility. Source of infection clinically, radiologically or microbiologically confirmed.
Maternal death or near-miss.
At least one WHO near-miss criteria. Geographical areas in six western European countries (Belgium, Denmark, Italy, Spain, the Netherlands, the UK) did not collect data on WHO near-miss criteria.
