Bacterial Meningitis among Intracranial Surgery Patients at a University Hospital in Northern India.

BACKGROUND

Cerebrospinal infections are the cause of poor prognosis among post-neurosurgery patients owing to delay in improvement of neurological functions, leading to increased length of hospital stay, proceeding to disability or death.

METHODS AND MATERIALS: This retrospective observational study was performed at a tertiary care center in Northern India, where all patients with bacterial cerebrospinal infections from July 2019 to July 2022 were evaluated for post-neurosurgery cerebrospinal shunt infections, and all demographic data and risk factors were extracted from the hospital information system (HIS).

RESULTS

The study includes 150 (150/1986, 7.55%) culture-confirmed cases of bacterial meningitis out of 1986 cases of suspected bacterial meningitis patients. Ninety-six (96/150, 64.0%) post-neurosurgery patients with cerebrospinal fluid (CSF) leaks were managed using external ventricular drain (EVD) or ventriculoperitoneal (VP) shunt. Seventy-four (74/96, 77.08%) patients were managed only on EVD, whereas 22 (22/96, 22.92%) patients were managed only on VP shunt. Eighty-two (82/96, 85.4%) multidrug-resistant microorganisms (MDROs) were isolated and 70 (70/82, 85.36%) were gram-negative bacteria, of which 56 (56/74, 75.68%) gram-negative bacteria showed extended-spectrum beta-lactamase (ESBL)-producing character in those with an EVD, 14 (14/22, 63.63%) with a VP shunt. Among gram-negative bacteria, Acinetobacter baumannii showed high rates of resistance: 21 (21/23, 91.30%) and 8 (8/8, 100%) were ESBL-producing A. baumannii in patients managed on EVD and VP shunt, respectively.

CONCLUSION

This study determines the risk factors, the spectrum of pathogenic microorganisms, multidrug resistance, and the nature of intracranial lesions isolated among the patients who developed bacterial cerebrospinal infections in post-neurosurgery patients.
