SAMM\u2010related diagnoses were defined by matching as closely as possible with published definitions. Outcomes included annual SAMM event rates, hospital survival, and hospital length of stay (LOS). Temporal trends were analysed using mixed\u2010effects generalised linear models.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>There were 854\u00a0777 live births and 1.21 million pregnancy\u2010related hospital admissions which included 34\u00a0008 SAMM events in 29\u00a0273 records and in 3.42% (95%CI\u00a0=\u00a03.39\u20133.46) of births. Most common were severe pre\u2010eclampsia (0.87% of births), severe postpartum haemorrhage (0.59%), and sepsis (0.62%). SAMM\u2010related admissions were associated with longer LOS and higher mortality risk (<jats:italic>P<\/jats:italic>\u00a0&lt;\u00a00.001).
