Cyberattacks targeting healthcare systems have been growing in prevalence and are wreaking more havoc with the healthcare industry’s increased dependence on electronic systems. Cyberattacks such as denial-of-service attacks, can have immediate impact on patient care by leaving medical staff without important patient records. The impacts don’t end there. With healthcare systems increasing their cybersecurity protocols in the aftermath of a cyberattack, patient information can be harder to access for those who should be accessing that information. Johnson’s research with co-author S.J. Choi, PhD, shows that at hospitals where security protocols slowed computer access by just a minute or so, people who came in with a heart attack were more likely to die. “When I talk to doctors about security, a lot of times they’re very negative,” Johnson said. “So they’re pretty far behind, and at this point, incredibly vulnerable.” It’s certainly not a stretch, Johnson says, to say that delays from a ransomware attack are likely to have more serious effects.
