Results  The indicators for wind speed, carbon dioxide, carbon monoxide, formaldehyde, inhalable particulate matters and illumination were qualified. The qualified rate for temperature, bacteria counts was 88% and 82.67%, respectively. Noise was unqualified in all places. Among 15 monitored hospitals, 9 hospitals had only 1 unqualified indicator, accounted for 60%, 4 hospitals had 2 unqualified indicators, accounted for 26.67%; 2 hospitals had 3 unqualified indicators, accounted for 13.33%.
