Severity level was determined only for those who had completed all the necessary information, where diagnosis and site of treatment had been determined for all cases.

Retrospective descriptive and comparative study of 403 patients’ files was done according to exclusion and inclusion criteria. Data entry analysis statistical program for social sciences version 16 (SPSS ver. 16) was used. For comparative evaluations the following statistical test were used; one sample T test, T test for independent variables and one way ANOVA. The main objective of this research is to evaluate the diagnostics and therapeutic procedure using CURB-65 to assess CAP patients including the need for hospitalization. Three hundred fifty EGFR inhibitor seven patients were treated as out-patients and 46 patients were treated as in-patients. The mean age was 31 years, compared with the cut-point in the risk calculation (65-year-old). There were no significant differences between the mean of age among male and female genders (P = 0.66; 95% CI) using T test for significant differences. The mean of respiratory rate values is 23 bpm. This value was compared with the cut-point in the risk calculation (30 bpm). Females demonstrated higher respiratory rates than males and this difference was significant with P = 0.014; (95% CI using

T test for independent variables). It is worth mentioning that the number of male cases with available respiratory rate data was 119 (22.6% children, 74.7% adult and 2.5% elderly) but it was only 60 for female gender (36.6% children, 58.3% adult and Apoptosis Compound Library 5% elderly). There was a significant difference between the respiratory rate mean for children, adults CYTH4 and the elderly with the highest value for children,

then the elderly, then adults (P = 0.0001; 95% CI) using one way ANOVA. There was no significant differences between the mean of urea value among male and female genders (P = 0.67; 95% CI). T test was used for the significant differences of independent variables. It is worth mentioning that the number of male cases with available urea data was 51 but it was only 21 for the female gender. The mean urea level mean was 9.4 mmol/l, which was compared with the cut-point in the risk calculation (7 mmol/l = 19.6 mg/dl). There was no significant difference in the mean urea value between the children, adults and the elderly with (P = 0.35; 95% CI) using one way ANOVA. Females had a higher mean blood pressure reading than males but this was not significant (P = 0.24 for both SBP and DBP; 95% CI). SBP and DBP measurements means were 127 mmHg and 77 mmHg respectively. These values were compared with the cut-point in the risk calculation (90 mmHg and 60 mmHg respectively). There were significant differences in SBP and DBP between children, adult and elderly with (P = 0.
