===== Procedural Success =====

**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

==== Binary Outcome for CUSUM ====

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.

==== Importance ====

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.
