Human factors play a vital role in the outcome of percutaneous dilatational tracheostomy

Excerpt

In a recent issue of Critical Care, we read with great interest the report by Simon and colleagues [1] on fatal complications of percutaneous dilatational tracheostomy (PDT). We agree with the authors’ suggestions for improving the safety of this procedure, but we think these improvements cover only part of the picture. We have previously concluded that PDT is a high-risk procedure [2]. This led us to perform a risk assessment of PDT in the ICU, where we found that several non-technical factors also influence the outcome of PDT [3]. In our risk assessment, we focused on the same two complications that Simon and colleagues identified as the most common: bleeding and airway complications. Similar to the findings by Simon and colleagues, our findings identified technical causes for the complications, but these technical causes were influenced by several non-technical factors (risk-influencing factors), like operator experience, culture and attitudes of the team, and protocol quality. …
