Clinical And Microbiological Analysis Of Hospital-Acquired Pneumonia Among Patients With Ischemic Stroke: A Retrospective Outlook

BackgroundHospital-acquired pneumonia (HAP) is a leading cause of morbidity and mortality in patients with ischemic stroke. Our study aims to explore the clinical and microbiological aspects (culture and sensitivity) of stroke patients with a confirmed diagnosis of HAP.MethodologyThis retrospective cross-sectional study included a total of 232 patients with a confirmed diagnosis of HAP following ischemic stroke. HAP was diagnosed based on the timing of onset of symptoms and chest X-ray. Patients were evaluated for their demographic details and a myriad of clinical parameters including dysphagia, mechanical ventilation, mortality, spontaneous pneumothorax, and Glasgow coma scale (GCS) score. The frequencies of different microorganisms isolated from the tracheal secretions were reported. Thereafter, the percentages of resistant isolates against a plethora of antimicrobial agents were tabulated.ResultsOut of 232 patients, 110 were males and 122 were females with a mean age of 58.79 +/- 8.62 years. Dysphagia and mechanical ventilation were present in 66.4% and 72%, respectively. The mortality rate was 30.6%. Klebsiella pneumoniae was the most frequently isolated organism (28.9%), followed by Escherichia coli (24.5%), and Pseudomonas aengthosa (23.3%). The antimicrobial resistance patterns of most of the isolates against different antibiotics were alarmingly high.ConclusionsDysphagia and mechanical ventilation are frequently present in patients of ischemic stroke with associated HAP. The antimicrobial resistance patterns of the isolated organisms are a cause of major concern. This necessitates the need for proper sanitation and the careful use of antibiotics.
