male and females patients were included in this study. Results: It was found that 480 (60%)
were males and 320 (40%) were females, males were significantly more frequent (c2=0.48,
p˂0.05) than the females patients. There was a significance difference in numbers of different
age group patients. According to the age distribution, there were 222(27.75%) from 1-5 years,
which was the highest among the patients and there were 44(5.5%) from 81-90 years of age
group patients, which was least among the different age group patients. According to the
comorbidity most of the patients were found without comorbidity there were 456(57%) patients

in married patients, married patients status were much higher at hospital C and hospital D
(c2=60.31, p˂0.05). According to the PSI segregation there were 424(53%) patients from PSI
class I, 168(21%) were from PSI class II, 128(16%) patients were from PSI class III, 44(5.5%)
were from class IV and 36(4.5%) were from PSI class V. Mean length of stay (LOS) was greater
at hospital C and D as compare to other two hospitals. Conclusion: CAP is frequent among
