A database was set up using Microsoft Excel 2003. Data was checked, cleaned, and analyzed using SPSS software version 11.5. Ninety-five percent confidence interval of means (95% CI) was used to describe PHE preparedness capacities. Categorical variables were analyzed with frequency and percentage. Comparisons of mean score of each of eight PHE preparedness capacities among different types of hospitals were performed with P < 0.05 as statistical significance using parameter test (Independent-Samples T Test (two-tailed) or One-way Analysis of Variance) and/or non-parameter test (Mann-Whitney Test or Kruskal-Wallis Test) based on data distribution characteristics and homogeneity.
