Twelve hospitals--five form Warsaw, three from Kraków, and four from Gdańsk and Gdynia were randomized for the study. The logistic preparedness of hospitals during massive chemical accidents has been investigated. There were 146 probands (9 managers, 31 ward heads, 75 assistants and 31 ward nurses) included in the study. In statistical analysis the generalized linear model extended by random factors, particularly the Poisson's regression has been used. No hospital in the three big cities in the country was prepared for any logistic action in case of massive chemical disaster. There were no stationary and mobile decontamination units in the investigated hospitals. There was no individual protective equipment in any of the analyzed hospitals. There were serious deficits in assortment and amount of antidotes which can be used in the treatment of contaminated patients. As much as 97.2% of respondents pointed the poison information centers as a main source of information in case of chemical accidents.
