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).
