Central Thailand was severely affected by black-water flooding between September and November 2011, with resultant closure of 30 regional hospitals. Few data are available for the incidence of nosocomial infections and patterns of preflood versus postflood multidrug-resistant organisms (MDROs) and mold. We therefore conducted a survey of the hospitals in central Thailand in order to evaluate the patterns of nosocomial infections, MDROs, mold, and flood preparedness plans after these floods.
On the basis of a hospital list from the Ministry of Public Health, we identified 104 hospitals in 15 provinces of central Thailand that were affected, but not necessarily closed, by extensive floods. We designed and then conducted a survey, from July 1 through October 31, 2012, that inquired about hospital characteristics, postflood hospital preparedness plans, administrative support, institutional safely culture, incidence of nosocomial infections, and prevalence of MDROs and mold colonization or infection. All 104 secondary care (>100 beds) and tertiary care (>250 beds) hospitals in 15 central Thailand provinces were invited to participate.
