From Wikipedia, the free encyclopedia

Bishop score, also Bishop's score, is a pre-labour scoring system to assist in predicting whether induction of labour will be required.^[1]

[edit] Components

The total score is achieved by assessing the following five components on vaginal examination:

Cervical dilatation
Cervical effacement
Cervical consistency
Cervical position
Fetal station

[edit] Scoring

Each components is given a score of 0-2 or 0-3. The highest possible score is 13.

**Bishop score**
Parameter\Score	0	1	2	3
Position	Posterior	Intermediate	Anterior	-
Consistency	Firm	Intermediate	Soft	-
Effacement	0-30%	40-50%	60-70%	80%
Dilation	<1 cm	1-2 cm	2-4 cm	>4 cm
Fetal station	-3	-2	-1, 0	+1, +2

[edit] Interpretation

A score of 5 or less suggests that labour is unlikely to start without induction. A score of 9 or more indicates that labour will most likely commence spontaneously.^[2]

[edit] Modified Bishop score

According to the Modified Bishop's pre-induction cervical scoring system, effacement has been replaced by cervical length in cm, with scores as follows- 0>3cm, 1>2cm, 2>1cm, 3>0cm.^[3]
