Key Points

The aim is to evaluate the effectiveness of metagenomic next-generation sequencing (mNGS) in diagnosing central nervous system infections after craniotomy.
Utilized metagenomic next-generation sequencing to identify microorganisms in CNS infections post-surgery
Compared mNGS results with traditional culture methods to assess diagnostic accuracy
Analyzed the impact on misdiagnosis rates and personalized treatment plans
mNGS was effective in detecting hard-to-cultivate microorganisms associated with CNS infections
Combining mNGS with traditional culturing improved overall diagnostic certainty

Abstract

mNGS detects post-neurosurgery CNS infections, especially hard-to-cultivate microorganisms. While mNGS has advantages, traditional culture's higher positive predictive value confirms infections and remains indispensable. Combining mNGS with traditional methods provides a comprehensive diagnostic strategy, aiding physicians in accurately identifying infections, reducing misdiagnosis, and offering personalized treatment plans to improve outcomes and quality of life.
