HT Médica
From a lack of visibility to proactive optimization of a critical healthcare platform
Executive summary
Industry: Healthcare and diagnostic imaging
Environment: Microsoft SQL Server supporting critical healthcare applications
Challenge: Performance problems in a business platform whose root cause was not clearly identified.
Goal: Find the root cause of degradation and establish preventive monitoring.
Result: Database design problems identified, performance improved and incidents anticipated.
The client
HT Médica is a healthcare organization specializing in diagnostic imaging, with more than 45 years of experience. It has become a national reference in advanced radiology, digital pathology and artificial intelligence applied to clinical diagnosis.
Its daily activity depends on critical applications managing medical and clinical information, making system availability, stability and performance essential to the quality of its service.
“Our patients are the most important thing. We are committed to offering a service based on quality, innovation and first-class technology.”
The challenge
HT Médica's growth significantly increased the load on its information systems and databases. The healthcare platform began showing saturation and bottlenecks, affecting applications supporting clinical activity.
Although the issue initially appeared to be related to infrastructure capacity, the technical analysis showed that the available hardware was sufficient. The real challenge was identifying which database components caused the degradation and how to correct them.
The organization needed:
- Complete visibility into SQL Server behavior.
- Real-time analysis of database activity.
- The ability to identify bottlenecks and problematic queries.
- Tools to anticipate incidents before they affected the service.
- A sustainable long-term monitoring model.
The solution
With IaaS365, HT Médica evaluated Four9s through a proof of concept aimed at finding the source of its problems and establishing a continuous observability strategy.
From the first days of use, Four9s identified previously hidden behavior and provided detailed information about queries, stored procedures, data access and design elements limiting platform performance.
Real-time monitoring, historical analysis and diagnostic capabilities allowed the technical team to understand the root cause and act directly on it.
“Four9s was like a Rosetta Stone: it helped us discover where the failure came from and locate the conceptual design problems in our database architecture.”
“Four9s focuses exactly on what we need. It lets us quickly identify which processes affect performance and locate the problem before it impacts the business.”
Results
Four9s completely changed how HT Médica managed database performance. Its technical teams can now:
- Detect anomalies before they become incidents.
- Identify procedures and queries affecting performance.
- Understand each process's real impact on the platform.
- Reduce diagnosis and resolution times.
- Optimize logical database design.
- Improve the stability of healthcare applications.
The organization also confirmed that the performance problems did not require more infrastructure, but optimization of specific database components, avoiding unnecessary investment.
Business impact
Four9s helped HT Médica move from a reactive model to a preventive strategy based on continuous observability. The organization now has a complete view of its critical systems, reducing operational risk and improving service quality.
“Implementing Four9s has been a success. It has given us visibility, prevention, service improvement and, above all, peace of mind.”
