HIV Needle Stick Risk Assessment Stratification Protocol (RASP)

Description

Estimates the risk of HIV transmission following occupational exposure (needle stick, mucous membrane, or non-intact skin contact) and provides Post-Exposure Prophylaxis (PEP) recommendations based on CDC guidelines.

Usage

rasp_hiv_risk(source_status, exposure_type, deep_injury_or_visible_blood,
              source_viral_load_high)

Arguments

source_status	String. Status of the source patient. Options: "positive", "negative", "unknown".
exposure_type	String. Type of exposure. Options: "percutaneous" (needle stick/cut), "mucous_membrane" (splash to eye/mouth), "non_intact_skin" (abrasion/dermatitis).
deep_injury_or_visible_blood	Numeric (0 or 1). Was the injury deep or was there visible blood on the device? (1 = Yes).
source_viral_load_high	Numeric (0 or 1). Is the source known to have a high viral load or acute HIV infection? (1 = Yes).

Value

A list containing:

Estimated_Transmission_Risk	The estimated probability of seroconversion (e.g., 0.3% for percutaneous).
PEP_Recommendation	Guidance on initiating Post-Exposure Prophylaxis.

Examples

# Example 1: High Risk Needlestick
# Source Positive, Percutaneous, Deep injury
rasp_hiv_risk("positive", "percutaneous", 1, 1)

# Example 2: Lower Risk Splash
# Source Positive, Mucous membrane splash
rasp_hiv_risk("positive", "mucous_membrane", 0, 0)

# Example 3: Source Negative
# No risk
rasp_hiv_risk("negative", "percutaneous", 1, 0)
