"Clinical, Laboratory and Etiological Profile of Community Acquired Pneumonia in Elderly."

Abstract

Background: Community Acquired Pneumonia (CAP) is third leading cause of death in older people worldwide. Apart from typical symptoms the elderly present with atypical symptoms. The diagnosis of pneumonia and its treatment poses a challenge for clinicians. Aim and Objectives: The study was undertaken to study clinical, radiological and bacterial profile of CAP in elderly (> 60years). Material and Methods: The elderly patient population consisted of 63 patients admitted with the diagnosis of CAP, as defined by British Thoracic society, were included in this prospective observational study over 24 months. Results: Among 63 patients, males were 38(60%) and females 25(40%), predominantly between the age group 60-74 years. Diabetes mellitus 12(19%) and anaemia 12(19%) were common co-morbidities. Cough 62(98%) was predominant presenting symptom. Patients presenting with atypical symptoms were 19(30%). Staphylococcus aureus was commonly isolated organism in 20(32%) patients on sputum examination. Left lower zone was commonly involved in 29(47%) on chest radiogram. The commonest complication was acute kidney injury in 9(15%).The overall mortality was 13% in this study group. Conclusion: CAP in elderly is a serious problem in clinical practice. In view of atypical presentation and associated co-morbidities, there is a delay in diagnosis, treatment initiation which may result in to high mortality. Early recognition, health education and awareness regarding pneumococcal vaccination are necessary.
