modified_bishop_score: Modified Bishop Score for Vaginal Delivery

Description

Calculates the Modified Bishop Score to assess the readiness of the cervix for induction of labor. The score evaluates five parameters: Dilation, Effacement, Station, Consistency, and Position. A higher score indicates a more favorable cervix for successful vaginal delivery.

Usage

modified_bishop_score(dilation_cm, effacement_percent, station,
                      consistency, position)

Value

A list containing:

Bishop_Score

The calculated total score (Range 0-13).

Interpretation

Clinical assessment (Favorable > 8, Unfavorable < 6).

Arguments

dilation_cm

Numeric. Cervical dilation in centimeters. 0 cm: 0 pts. 1-2 cm: 1 pt. 3-4 cm: 2 pts. >= 5 cm: 3 pts.

effacement_percent

Numeric. Cervical effacement percentage. 0-30%: 0 pts. 40-50%: 1 pt. 60-70%: 2 pts. >= 80%: 3 pts.

station

Numeric. Fetal station relative to ischial spines (-3 to +2). -3: 0 pts. -2: 1 pt. -1, 0: 2 pts. +1, +2: 3 pts.

consistency

String. Consistency of the cervix. Options: "firm" (0 pts), "medium" (1 pt), "soft" (2 pts).

position

String. Position of the cervix. Options: "posterior" (0 pts), "midposition" (1 pt), "anterior" (2 pts).

Examples

# Example 1: Favorable Cervix
# 4cm dilated (2), 60% effaced (2), -1 station (2), Soft (2), Anterior (2)
# Score = 10
modified_bishop_score(4, 60, -1, "soft", "anterior")

# Example 2: Unfavorable Cervix
# Closed (0), 30% effaced (0), -3 station (0), Firm (0), Posterior (0)
# Score = 0
