glasgow_imrie_pancreatitis_score: Glasgow-Imrie Criteria for Acute Pancreatitis Severity

Description

Calculates the Glasgow-Imrie Score (Modified Glasgow Score) to assess the severity of acute pancreatitis within the first 48 hours of admission. The score utilizes the mnemonic PANCREAS to evaluate 8 prognostic factors. A score of 3 or greater indicates severe pancreatitis.

Usage

glasgow_imrie_pancreatitis_score(age, wbc, glucose, urea, pao2, albumin,
                                 calcium, ldh, ast, alt,
                                 glucose_units = "mmol/L",
                                 urea_units = "mmol/L",
                                 calcium_units = "mmol/L",
                                 albumin_units = "g/L")

Value

A list containing:

Glasgow_Imrie_Score

The calculated score (Range 0-8).

Severity_Assessment

"Severe Pancreatitis" if Score >= 3, otherwise "Mild Pancreatitis".

Arguments
