Abstract	Ransomware represents a distinctive threat to healthcare because cyber disruption can simultaneously affect confidentiality of health information, financial operations, clinical documentation, diagnostic workflows, medication processes, scheduling, communications, and continuity of patient care. Smaller healthcare organizations face a particularly difficult preparedness problem because they may depend heavily on electronic health records and external technology providers while operating without dedicated cybersecurity teams. The 2020 Health Industry Cybersecurity Practices technical guidance for small healthcare organizations explicitly recognizes that smaller providers frequently have limited dedicated information-technology and security staffing and may rely on managed service providers for network, security, cloud, backup, and electronic-health-record functions. Current HHS Healthcare and Public Health Cybersecurity Performance Goals consequently prioritize practices including vulnerability mitigation, email security, multifactor authentication, workforce training, incident planning, unique credentials, separation of privileged accounts, vendor-risk management, network segmentation, threat detection, centralized logging, and incident-response exercises. This study develops an adaptive ransomware-preparedness framework specifically for small healthcare organizations. Rather than treating preparedness as a static checklist, the proposed model adjusts priorities according to clinical criticality, technology dependence, current threat exposure, backup recoverability, third-party concentration, workforce readiness, and available cybersecurity resources. A synthetic dataset representing 360 small healthcare organizations and 7,200 ransomware-response scenarios was generated. Four preparedness conditions were compared: minimum reactive security, basic preventive controls, resilience-focused preparedness, and adaptive clinical cyber resilience. Evaluation considered attack-containment readiness, protected-backup recoverability, clinical-continuity readiness, mean projected service disruption, third-party resilience, and composite preparedness. The adaptive condition produced a simulated composite preparedness score of 91.2 compared with 43.8 for the reactive baseline. Projected clinical service disruption declined from 72 hours in the baseline scenario to 12 hours after sequential introduction of tested immutable backups, rehearsed clinical downtime procedures, multifactor authentication and segmentation, third-party contingency planning, and rapid detection and containment.
