Decision analysis computer program for use in the labor room.

A decision analytic model (a decision tree) was constructed for use in the labor room. Probabilities and (dis)utilities were estimated by obstetricians and computerized. A sensitivity analysis on six branches of the decision tree uses estimates of four obstetricians and proves that the decisions resulting from the model are stable and insensitive to differences in probability estimates within reasonable limits. Therefore it is concluded that we can construct a decision tree that is a practical, valuable, and stable tool for consistent decision making.
