Cybersecurity Threats and Patient Safety in Digital Healthcare Systems: A Narrative Review

Abstract

The rapid digital transformation of healthcare systems has significantly improved healthcare delivery through the adoption of technologies such as electronic health records, telemedicine platforms, artificial intelligence–supported diagnostics, and network-connected medical devices. While these innovations enhance clinical decision-making and healthcare accessibility, they have also increased the exposure of healthcare institutions to cybersecurity threats. Healthcare organizations have become attractive targets for cybercriminals due to the high value of medical data, the complexity of digital infrastructures, and the operational urgency of clinical services. Cyberattacks including ransomware incidents, data breaches, phishing and social engineering attacks, insider threats, and exploitation of connected medical devices—can disrupt healthcare operations and compromise patient safety. This narrative review examines the evolving cybersecurity threat landscape in digital healthcare systems and analyzes how cyber incidents affect healthcare delivery and patient safety. Relevant literature was identified through searches of major academic databases including PubMed, Scopus, and Web of Science, alongside additional sources from policy reports and cybersecurity research publications. The review synthesizes current evidence on how cyberattacks interfere with clinical workflows, delay diagnosis and treatment, and undermine the reliability of digital medical technologies. The findings highlight major cybersecurity risks affecting healthcare systems and discuss mitigation strategies involving technical security controls, organizational preparedness, and regulatory frameworks. Strengthening cybersecurity resilience through integrated governance, workforce awareness, and proactive security measures is essential to protect patient data, maintain healthcare system reliability, and ensure safe delivery of care in increasingly digital healthcare environments.
