Key Insights:

• Healthcare organizations must maintain emergency cash reserves
• Cybersecurity incidents can create immediate cash flow crises
• Financial preparedness is essential for incident response
• Lines of credit may be necessary for cybersecurity incidents

3. Manual Process Readiness

Critical Finding: Many Massachusetts healthcare facilities struggled to implement manual, paper-based processes when electronic systems were unavailable, revealing gaps in business continuity planning.

Key Insights:

• Healthcare organizations must maintain manual process capabilities
• Business continuity plans must be regularly tested
• Staff training on manual processes is essential
• Documentation of manual procedures must be current

4. Vendor Cybersecurity Assessment Gaps

Critical Finding: Many Massachusetts healthcare providers had not conducted comprehensive cybersecurity assessments of Change Healthcare before the incident, highlighting gaps in vendor risk management programs.

Key Insights:
