pews_score: Pediatric Early Warning Score (PEWS)

Description

Calculates the Pediatric Early Warning Score (PEWS) based on the Monaghan (Brighton) methodology. This score is used to identify pediatric patients at risk for clinical deterioration. It evaluates three physiological domains (Behavior, Cardiovascular, Respiratory) and includes adjustments for nebulizer use and persistent vomiting.

Usage

pews_score(behavior_score, cardiovascular_score, respiratory_score,
           nebulizer_use, persistent_vomiting)

Value

A list containing:

PEWS_Score

The calculated total PEWS score.

Risk_Level

Risk stratification (Low, Low-Intermediate, Intermediate, High).

Action_Guidance

Suggested clinical response based on the score.

Arguments

behavior_score

Numeric (0-3). 0: Playing/Appropriate. 1: Sleeping. 2: Irritable. 3: Lethargic/Confused or reduced response to pain.

cardiovascular_score

Numeric (0-3). 0: Pink or Capillary Refill (CRT) 1-2s. 1: Pale or CRT 3s. 2: Grey or CRT 4s or Tachycardia of 20 bpm above normal. 3: Grey/Mottled or CRT >=5s or Tachycardia of 30 bpm above normal or Bradycardia.

respiratory_score

Numeric (0-3). 0: Within normal parameters, no recession. 1: >10 above normal RR, using accessory muscles, or 30%+ O2 (or >2L/min). 2: >20 above normal RR, recession, or 40%+ O2 (or >4L/min). 3: 5 below normal RR with retractions/grunting, or 50%+ O2 (or >6L/min).

nebulizer_use

Numeric (0 or 1). Use of nebulizer treatment (e.g., every 15 minutes). (1 = Yes, +2 points).

persistent_vomiting

Numeric (0 or 1). Presence of persistent vomiting following surgery. (1 = Yes, +2 points).

Examples

# Example 1: Stable Patient
# Behavior 0, CV 0, Resp 0, No neb/vomit

# Example 2: High Risk Patient
# Lethargic (3), Grey (2), Retractions (2), On Nebs (1)
# Score = 3 + 2 + 2 + 2 = 9
