|Comparison of visitors, health care waste generation rates and categories of HCW using Kruskal-Wallis test among the surveyed hospitals, 2011|
|Name of hospital||Mean Ranks|
|Patient flow||Total HCW||Non-HW||HW|
|St. Yared gen.||7.14||5.86||7.71||24.86|
According to Table 4, the Spearman’s rank correlation coefficient (rs) showed that there was a positive linear relationship between number of patients and quantities of HCW generation rates (p < 0.05). A positive linear relationship was also observed between total amount of HCW generated and number of hospital beds with (rs=0.943, p < 0.05).
