The Attributable Direct Medical Cost of Healthcare Associated Infection Caused by Multidrug Resistance Organisms in 68 Hospitals of China

Abstract EN

Healthcare associated infection (HAI) is known to increase the economic burden of patients while the medical cost due to MDRO HAI is even higher.

Three hundred eighty-one multidrug resistance organisms (MDROs) healthcare associated infection (HAI) case-patients and three hundred eighty-one matched control-patients were identified between January and December in 2015.

The average total hospitalization medical cost of the case group was $6127.65 and that of the control group was $2274.02.

The difference between the case group and the control group was statistically significant (t = 21.07; P < 0.01).

The attributable cost of MDRO HAI was $3853.63.

The direct medical costs due to different MDRO infections were different.

The increased medical costs of CR-AB, CR-KP, and CR-PA were significantly higher than that of MRSA, MRSE, ESBL E.

coli, and ESBL Kp (P < 0.

05).

Among the subitem expenses, the drug cost increased the most (the average cost was $1457.72), followed by the treatment fee and test fee; the differences were statistically significant (P < 0.01).
