9Benchmarking and patient safety in hypertensive disorders of pregnancy

Hypertensive disorders of pregnancy are a major cause of morbidity and mortality worldwide. Reliable, published individual patient data from units and countries are lacking. Without these data, clinicians are unable to benchmark their incidence, treatments and outcomes, and patient safety is unable to be routinely assessed. Available data suggest that a notable proportion of the adverse events that occur with hypertensive disease of pregnancy may be preventable. Theory and practice indicate several methods that can offer the possibility of averting these preventable adverse events. These methods include benchmarking outcomes, standardisation of care processes, simulation, and enhancement of patient knowledge. However, data on optimal methods to enhance patient safety and quality of care of pregnant women with hypertensive disease remain limited, and further research is required.
