lips_score: Lung Injury Prediction Score (LIPS)

In cliot: Clinical Indices and Outcomes Tools

Lung Injury Prediction Score (LIPS)

Description

Calculates the Lung Injury Prediction Score (LIPS) to identify patients at high risk for developing Acute Lung Injury (ALI) or Acute Respiratory Distress Syndrome (ARDS). The score sums points for predisposing conditions (like shock, aspiration, sepsis) and risk modifiers (like alcohol use, obesity, and vital signs). A score of 4 or greater typically indicates high risk.

Usage

lips_score(shock, aspiration, sepsis, pneumonia, high_risk_surgery,
           high_risk_trauma, alcohol_abuse, obesity_bmi_gt_30, hypoalbuminemia,
           chemotherapy, fio2_gt_0_35_or_4l, tachypnea_rr_gt_30, spo2_lt_95,
           acidosis_ph_lt_7_35, diabetes_mellitus)

Arguments

shock	Numeric (0 or 1). Presence of shock (Cardiogenic, Septic, or Hypovolemic). (1 = Yes, +2 pts).
aspiration	Numeric (0 or 1). Aspiration. (1 = Yes, +2 pts).
sepsis	Numeric (0 or 1). Sepsis. (1 = Yes, +1 pt).
pneumonia	Numeric (0 or 1). Pneumonia. (1 = Yes, +1.5 pts).
high_risk_surgery	Numeric (0 or 1). High-risk surgery (Aortic vascular, Cardiac, Emergency, Spine). (1 = Yes, +2 pts).
high_risk_trauma	Numeric (0 or 1). High-risk trauma (TBI, Smoke inhalation, Near drowning, Lung contusion, Multiple fractures). (1 = Yes, +2 pts).
alcohol_abuse	Numeric (0 or 1). Alcohol abuse. (1 = Yes, +1 pt).
obesity_bmi_gt_30	Numeric (0 or 1). Obesity (BMI > 30). (1 = Yes, +1 pt).
hypoalbuminemia	Numeric (0 or 1). Hypoalbuminemia (Albumin < 3.5 g/dL). (1 = Yes, +1 pt).
chemotherapy	Numeric (0 or 1). Chemotherapy. (1 = Yes, +1 pt).
fio2_gt_0_35_or_4l	Numeric (0 or 1). FiO2 > 0.35 or > 4 L/min O2 (sometimes noted as >2 L/min in variations). (1 = Yes, +2 pts).
tachypnea_rr_gt_30	Numeric (0 or 1). Respiratory rate > 30 bpm. (1 = Yes, +1.5 pts).
spo2_lt_95	Numeric (0 or 1). SpO2 < 95%. (1 = Yes, +1 pt).
acidosis_ph_lt_7_35	Numeric (0 or 1). Acidosis (pH < 7.35). (1 = Yes, +1 pt).
diabetes_mellitus	Numeric (0 or 1). Diabetes Mellitus. (1 = Yes, -1 pt). Note: Diabetes is protective in this model.

Value

A list containing:

LIPS_Score	The calculated total score (Range -1 to >20).
Risk_Category	"Low Risk" (< 4) or "High Risk" (>= 4).
Recommendation	Clinical guidance for monitoring.

# Example 1: High Risk
# Shock (+2), Sepsis (+1), Acidosis (+1), Hypoalbuminemia (+1)
# Score = 5

# Example 2: Low Risk
# Pneumonia (+1.5), Diabetes (-1), No other factors
# Score = 0.5
lips_score(0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1)
