Abstract

Title. Effect of performance feedback on tracheal suctioning knowledge and skills: randomized controlled trial.

Aim.  This paper is a report of a study to determine whether individualized performance feedback improved nurses’ and physiotherapists’ knowledge and practice of tracheal suctioning.

Background.  Nurses’ knowledge and practice of tracheal suctioning is often deficient. Whilst teaching has been shown to improve suctioning knowledge and practice, this is not sustained over time.

Method.  Ninety-five qualified healthcare professionals (nurses and physiotherapists) in two acute hospitals were randomly allocated to receive either individualized performance feedback or no additional feedback after a standardized lecture and practical demonstration of tracheal suctioning. Randomization was stratified by profession, seniority and site. Data were collected in 2005 in a clinical setting involving patients and a simulation setting. The outcome measures were knowledge and practice of tracheal suctioning, assessed by self-completion questionnaire and structured observation.

Results.  In both settings, intervention groups performed statistically significantly better in terms of knowledge (P = 0·014) and practice (P = 0·037) at final follow-up. Those who received performance feedback had statistically significantly higher knowledge (P = 0·004) and practice (P < 0·01) scores than the control group. For practice, there was also a relationship between professions (P < 0·01), with physiotherapists performing better than nurses overall, and an interaction between group and setting (P < 0·01), with performance feedback showing a stronger positive effect in the simulation setting.

Conclusion.  Retention of knowledge and tracheal suctioning practice is improved when training is followed up by tailored feedback on performance. Further research would shed light on how long such improvements are sustained, and whether the improvements seen in a simulated setting can be generalized to clinical settings.
