Our study was unique in that it examined determinants of PE for medical device decision-making. Strengths included the use of rigorous qualitative methods, and analysis of the findings using existing frameworks of PE [1, 2] and PE for medical device decision-making . However, several limitations should be mentioned. The number of participants may appear small, but qualitative research is meant to capture detailed information from few, representative participants. Their views may reflect the Canadian health care setting and may not be transferrable to other settings. However, the devices they use are those used worldwide, and several issues that emerged were also revealed in other studies which support the reliability of these findings [27–29]. To mitigate this, sampling was purposive to capture perspectives from individuals with a variety of characteristics, and achieved thematic saturation which signals that recruitment is sufficient to identify themes, though not necessarily sufficient to explore the characteristics and implications of these themes. This would require larger samples from diverse backgrounds, and would be an interesting future study.
