Treatment outcome and associated factors of bacterial meningitis at pediatric wards of southwestern Ethiopian hospital: a prospective observational study

Abstract

Background: Meningitis is a common infectious cause of morbidity and mortality in pediatric age-groups. Acute bacterial meningitis is considered a medical emergency, because it is a life-threatening infection that requires immediate treatment. Therefore the study was aimed to assess the magnitude and predictors of poor treatment outcome among pediatric patients admitted to Bedele General Hospital.

Methods: A prospective observational study was conducted at pediatric wards of Bedele General Hospital from February 12, 2020 to August 11, 2020. Lumbar puncture, in the absence of contraindications, was performed under aseptic conditions for all patients with suspected bacterial meningitis to collect cerebrospinal fluid specimen. Multivariable logistic regression was used to determine the predictors of poor treatment outcome.

Result: Of the 196 pediatric patients involved, 112(57.1%) were male and the mean and standard deviation of their age was 6.09 ± 4.46. Regarding to their clinical profile, a total of 101(51.5%) were completely immunized and 115(58.7%) were given corticosteroid during their treatment. In our study the most frequently occurred clinical manifestation of meningitis was fever 164(83.67%), neck rigidity149 (76.02%), and irritability 122(62.24%). Regarding to their pharmacotherapy, the most commonly prescribed antibiotics were Ampicillin 104(24.82%), and Gentamycin 102(24.34%). The magnitude of good treatment outcome was 132(67.35%) whereas 64(32.65%) were poorly controlled. The presence of comorbidity (AOR = 3.64, 95CI%:1.83-7.23,P = < 0.001),corticosteroid use (AOR = 2.37, 95CI%:1.17-4.81,P = 0.017) and oxygen administration (AOR = 3.12, 95CI%: 1.34-7.25, P = 0.008) was a predictor of meningitis treatment outcome.

Conclusion: The treatment outcome of meningitis was good in of two-third of the patients. It was found that the presence of comorbidity, the administration of oxygen and use of corticosteroid was predictors of the treatment outcomes of bacterial meningitis in children. Therefore, in patients with these factors, appropriate meningitis treatment should be encouraged and locally applicable treatment guidelines should be prepared to improve patient outcome. Finally, the meningitis patients should be given corticosteroid and oxygen as treatment and special attention should be given for patients having co-morbidities.
