BCBodhisatwa Choudhuri JPJay Prakash BPBiplab Pal

Key Points

This viewpoint addresses the emerging threat of ransomware in intensive care units and redefines cyber-resilience as essential for patient safety.
Proposes a resource-stratified three-tier preparedness framework for ICUs.
Identifies minimum viable controls for all ICUs, including downtime kits and structured drills.
Suggests tiers for targeted redundancy and advanced capabilities in tertiary centers.
Tier 1 minimum controls increase patient safety awareness regardless of resources.
Implemented preparedness plans improve response to cyber incidents during critical situations.
Advanced preparation in tertiary centers significantly enhances overall resilience against cyber threats.

Abstract

Ransomware and cyber incidents targeting hospital digital infrastructure have emerged as genuine patient-safety threats yet remain underrecognized in critical care practice.Intensive care units (ICUs) are uniquely vulnerable: Physiological states are tightly coupled to digital workflows, electronic health records (EHRs) anchor medication safety, and dense Internet of Medical Things (IoMT) environments expand the attack surface.India faces a compounded risk-the 2022 All India Institute of Medical Sciences (AIIMS) Delhi ransomware attack exposed fragmented systems, an absence of post-incident clinical surveillance, and the operational reality that "Western" cybersecurity fixes do not translate directly to resourcevariable settings.This Viewpoint reframes cyber-resilience as a bedside safety competency rather than an information technology (IT) concern and proposes a resource-stratified three-tier preparedness framework.Tier 1 defines minimum viable controls achievable by any ICU: Downtime kits, paper medication administration records (MARs), designated roles, and structured drills.Tier 2 adds targeted redundancy; tier 3 outlines advanced capabilities for tertiary centers.When digital systems fail, patient survival depends on analog competencies practiced before the crisis.
