Aim & Objective: To evaluate the Etiology, Epidemiology, Antimicrobial sensitivity and Outcome of Community-Acquired Pneumonia (CAP).

Outcome: it will be measured at the end of study in term of Organism responsible for community acquired pneumonia, epidemiology and their antimicrobial sensitivity.

Design: Prospective epidemiologic study, to be done at MAX SUPER SPECIALITY HOSPITAL, SAKET, NEW DELHI

MATERIAL AND METHODS:-

All adult more than 18 years of age, between August, 2012 and July, 2013, who will be treated at Max Super Specialty Hospital (A Unit Of Max Healthcare Institute Limited), Saket, New Delhi with clinical diagnosis of community acquired pneumonia will be studied prospectively. It will include the patients that come in as out patients department or ER or inpatients department and occasionally patient admitted in other department with other presumptive illness and in whom a diagnosis of CAP made during the 24 hr of hospitalization

Patient demographic features will be recorded according to study proforma. A detailed clinical history will be taken. History for co morbid illness and habits like smoking and alcoholism are will be taken. Co morbid illnesses were defined as the presence of coexisting cardiac failure, ischemic heart disease, chronic lung disease (COPD), chronic liver disease (cirrhosis of liver), chronic kidney disease (diabetic nephropathy) and diabetes mellitus. A detailed clinical examination will be carried out including general physical examination, vital signs, and respiratory system examination, mainly for signs of consolidation and other systemic examination for the co morbid illness. Routine investigations like hemoglobin, total leucocytes count, differential count, ESR, random blood sugar, renal profile, liver function tests, spo2 and paired blood culture will be recorded. Radiological evaluation inform of chest x ray will be done. Sputum will be collected for gram stain and culture and sensitivity, other investigation will be recorded if they are done, are CRP, Procalcitonin and CECT chest.

Outcome of CAP will be measured in term of in clinical improvement OR lab parameter improvement OR radiological improvement.

A)    Clinical improvement includes-Body temperature, Pulse rate, Systolic BP, Respiratory rate and Spo2.

B)    Lab improvement includes-TLC,[CRP and Procalcitonin- if done].

C)    Radiological improvement by comparing day 1^st chest x- ray and last chest x- ray available at the time of discharge in IPD patients and follow up chest x- ray in OPD patients.
