01The Challenge
Hurricane Ernesto caused major disruptions across Puerto Rico, and healthcare organizations had to react quickly. Quantum 360, responsible for coordinating services across multiple medical centers, needed to:
Cancel and reschedule a large volume of medical appointments urgently
Reach patients individually with clear, personalized information
Minimize patient exposure to dangerous weather conditions
Ensure no one was missed, even as phone lines and staff workloads were overwhelmed
Traditional manual calling methods would have required several days and significant manpower—time they did not have in a rapidly evolving emergency.
02The Solution
To meet the urgency of the situation, Quantum 360 implemented SIP Caller’s power dialer and automation features, allowing them to:
Launch an outbound communication campaign in minutes
Contact over 600 patients quickly, with individualized messages
Automate retries and follow-ups for unreachable numbers
Maintain a clear audit trail of calls, statuses, and outcomes
Operate efficiently despite reduced staff availability during the storm
The dialer handled the heavy lifting, while staff focused on coordinating rescheduling and providing support where needed.
03The Results
600+
patients contacted in under 48 hours
Quantum 360 achieved fast, measurable impact during a critical moment:
600+ patients contacted in under 48 hours
Appointments cancelled and rescheduled individually and accurately
Reduced patient exposure to hazardous conditions
Improved crisis response efficiency
A new standard operational workflow established for future communications
Their CEO summarized the experience:
In critical moments, technology makes a difference. During the recent passage of Hurricane Ernesto through Puerto Rico, Quantum faced the challenge of canceling and rescheduling essential medical services in record time. Thanks to the predictive power of the SIP Caller dialer, we were able to contact more than 600 patients in less than 48 hours, managing the cancellation and rescheduling of appointments in an individualized, precise and timely manner. This significantly reduced the risk of exposure to the atmospheric phenomenon for patients and ensured effective communication in logistics management. Without a doubt, this is a tool that we will implement in our standard communications operations.
