Abstract

As cybercriminals increasingly target healthcare, hospitals face the growing threat of ransomware attacks. Ransomware is a type of malicious software that prevents users from accessing electronic systems and demands a ransom to restore access. In this paper, we create and link a database of hospital ransomware attacks to Medicare administrative claims data. We quantify the effects of ransomware attacks on hospital operations and patient outcomes. Ransomware attacks decrease hospital volume by 17-25% during the initial attack week, reducing revenue even further. We find that ransomware attacks increase in-hospital mortality for patients who are already admitted at the time of attack.
