Abstract

Aim: To audit obstetric outcomes for nulliparous laborers in order to provide accurate information to
our population. To establish a simple index by which a maternity unit's performance can be compared
over time and to other units. We named this index Maternity Unit Performance Index (MUPI).
Materials and method: Retrospective analysis of the obstetric outcome of all nulliparous singleton gestations, between 37 and prior to 41 gestational weeks, presenting to labor ward for delivery in the chronical periods 01.01.2005 to 31.12.2005, 01.01.1995 to 31.12.1995 and 01.01.1985 to 31.12.1985. Utilization of the MUPI formula to these chronical periods.
Results: Retrospective implementation of the MUPI formula resulted in lower scores as years
progress. MUPI scores for the years 2005, 1995 and 1985 were respectively 84.39, 113.61 and 126.87.
Conclusion: We have proposed a simple index of our unit's performance by which to counsel our first
time mothers. MUPI scores demonstrate a steady decrease as years pass. Interpretation of these results
suggests a continuously evolving obstetric practice rather than a decrease in the quality of obstetric
service provided.

Key words: Performance index; maternity unit; obstetric practice; nulliparity; caesarean section rate.
