Learning curves for TAVR: Not quite see one, do one teach one
1Cardiac Catheterization Laboratories, NorthShore University HealthSystem, Evanston, Illinois.
Summary
The learning curve for Transcatheter Aortic Valve Replacement (TAVR) was established using procedural data. Fewer cases were needed for later sites to achieve proficiency, indicating a shorter learning curve over time.
Area of Science:
- Cardiovascular Medicine
- Interventional Cardiology
- Medical Device Technology
Background:
- The PARTNER-1 Trial provided crucial technical data to assess the learning curve for Transcatheter Aortic Valve Replacement (TAVR).
- Understanding the learning curve is essential for safe and effective adoption of new cardiovascular procedures.
Discussion:
- Original sites required approximately 50 cases to reach a plateau in the TAVR learning curve.
- Sites entering the trial later demonstrated a reduced learning curve, needing around 25 cases to achieve proficiency.
Key Insights:
- Procedural learning for TAVR is influenced by site experience and potentially improved techniques over time.
- The data suggests a dynamic learning curve that can decrease as a technology matures and experience accumulates.
Outlook:
- These findings are vital for establishing training guidelines and benchmarks for emerging interventional technologies.
- Further analysis can inform best practices for TAVR programs and other complex medical procedures.

Tracheostomy Care I: Pre-procedural Steps
1.7K
A tracheostomy is a surgical technique that involves making an incision in the neck to provide access to the trachea. It is frequently used in medical conditions such as airway obstruction and prolonged mechanical ventilation. Effective nursing management is crucial for the long-term success of a tracheostomy.

Tracheostomy Care II: Procedure
2.2K
Tracheostomy care is an essential nursing skill that involves cleaning and maintaining a tracheostomy tube to prevent infection and other complications. Here's a step-by-step guide explaining each procedure with its rationale. Note that disposable gloves are to be worn at all times and changed as often as needed to maintain a sterile work environment, and to protect both patient and healthcare worker.

Errors in Taping
418
Errors in taping arise from multiple factors that can significantly impact measurement accuracy in surveying. Misalignment of the tape, often due to human error, is one primary source. A skilled rear tapeman, using a telescope, can help correct alignment by guiding the head tapeman; however, human limitations still lead to small inaccuracies. These errors may include misplacement of pins or inaccurate tape readings due to common visual confusions, such as mistaking a six for a nine. Such...
