Quantitative and qualitative evaluation for attributes of the surveillance system for MDRP infections in Japan.

A. The percentage of TDSSs among all hospitals in each prefecture. B. The percentage of hospitals with 300 beds or more among the TDSSs in each prefecture. The blue color scale indicates the distribution across each percentage range. We created the map by editing data ‘Global Map Japan’. TDSS, target designated sentinel site.

Trend in the number of cases reported as MDRP infections and the number of accurate MDRP infections at TDSSs, 2018–2022.
From 2018 to 2022, these TDSSs reported 277 cases as MDRP infections, while 184 cases were accurately reported MDRP infections, with both numbers decreasing over time. NESID, National Epidemiological Surveillance of Infectious Diseases; MDRP, multidrug-resistant Pseudomonas aeruginosa; TDSS, target designated sentinel site.

Distribution of TDSSs that misreported cases as MDRP infections and underreported accurate MDRP infections, 2018-2022.
A. Seventy-one TDSSs misreported a total of 162 cases as MDRP infections despite them not meeting the criteria. B. Thirty-one TDSSs underreported a total of 69 accurate MDRP infections. MDRP, multidrug-resistant Pseudomonas aeruginosa; TDSS, target designated sentinel site.
