A retrospective audit of tracheostomies performed within a set time frame can be used both to quantify numbers and to identify whether established guidelines and care packages are being implemented. Prospective data collection may take longer, depending on the frequency of tracheostomy insertion, but can include
aspects relating to the management of tracheostomies performed outside the critical care unit (CCU). Data collection can be coupled with educational events so that knowledge of practice related to tracheostomy can be consolidated among the multidisciplinary team. This can identify barriers to the implementation of best practice, which can be identified and addressed using a plan-do-study-act methodology.
