Not only did the New York City municipal government appropriate more money to the care of the mentally ill on Blackwell's Island, a grand jury was impaneled to investigate the abuses and poor treatments Bly uncovered at the asylum. Approximately one month after her articles ran in print, many of the most glaring problems she reported had improved: better living and sanitary conditions were instituted, more nourishing meals were provided, translators were hired for the foreign-born who were not necessarily mentally ill but simply could not understand their keepers, and the most abusive nurses and physicians were fired and replaced.
