Procedural success in intracranial pressure (ICP) monitor placement refers to the accurate and complication-free completion of the procedure, resulting in a functional monitoring system.

A case is typically considered successful if all of the following criteria are met:

• Correct anatomical placement (confirmed radiologically or clinically)
• Immediate and stable ICP waveform acquisition
• No intraoperative or early postoperative complications (e.g., hemorrhage, misplacement)
• No need for revision or replacement within 48–72 hours

In the context of CUSUM analysis, procedural success is coded as:

• 0 for success
• 1 for failure (any deviation from the above criteria)

This allows straightforward tracking and visualization of performance trends over time.

Measuring procedural success consistently enables:

• Objective monitoring of technical performance
• Early identification of training needs
• Benchmarking against institutional or published standards
• Targeted interventions to reduce avoidable complications

In high-stakes environments like neurocritical care, even subtle declines in procedural success can have significant clinical impact, reinforcing the value of routine outcome tracking.
