A Study on Clinical Profile and Outcome of Bilateral Pneumonitis

Abstract

Our study focussed purely on bilateral pneumonitis (both infective and non-infective) which evolved in the community excluding all hospital acquired, aspiration pneumonitis developed in the hospital/ICU settings, malignancy and immunocompromised state where risk of bilateral involvement of lungs is very high. Objectives: To analyse the clinical, etiological and radiological features of bilateral pneumonitis, to study mortality in patients with bilateral pneumonitis in relation to PSI grading. Methodology: Study Design: Observational study, Study Population: All the patients who were diagnosed with bilateral Pneumonitis at OPD/emergency wards and later admitted in medical or disaster wards, Study Setting: RL JALAPPA HOSPITAL, KOLAR, Study Period: 4 months, Sample size: 300. Results & Discussion: In the present study, the mean age group of the patients was 49.30 ± 13.47. Mahendra8 et al reported that mean age of the patients was 54.03 years. Nagesh kumar9 et al reported that the mean age of the patients studied was 56.07± 16.52 years. Bronchopneumonia was the commonest chest X-ray finding in the present study. Nagesh Kumar9 et al reported that the most common chest radiograph finding was lobar consolidation in 44.2% of all cases, followed by patchy consolidation in 39.3% of the cases. Interstitial pattern was observed in 4.9% of cases and cavitory lesions were seen in one case, which was positive for S. aureus. In the present study no mortality seen in PSI class II and III but it is around 23.35% (39 patients) in PSI class IV and 69.04% (29 patients) in PSI class V. More than 50% died in PSI class V due to dreadful complications of pneumonitis and MV/NIV adverse effects.Kim16 et al in their study on Pneumonia severity index in viral community acquired pneumonia in adults reported that In the PSI class V, the mortality rate was 27 times that of the PSI class I.
