Defining obstetric terms: The need for gold standards

Summary

To test the hypotheses that: (1) standard definitions of common obstetric terms exist and (2) frontline workers in daily obstetric practice have common understandings of these terms, we undertook (a) a review of definitions for nine common terms from latest editions of standard texts and resources, and (b) an exploratory questionnaire survey of these definitions applied in a work setting among four groups; trainee and consultant obstetricians, student and qualified midwives (five of each). Definitions for nine selected obstetric terms in common use (labour, parity, precipitate labour, primary postpartum haemorrhage, primiparity, PROM, secondary postpartum haemorrhage, term and viability) were inconsistent in standard texts. Obstetric staff had no agreed perception of the precise definitions. There is a potentially hazardous lack of clarity about obstetric terms, and a need to develop standard definitions. This would benefit students, practitioners, information technology experts and, most importantly, patients.
