Qualitative research in critical care: Has its time finally come?

As clinicians, we are well acquainted with using randomised controlled trials, case-control studies and cohort studies together with p-values, odds ratios and confidence intervals to understand and improve the way in which we care for our patients. We have a degree of familiarity, trust and confidence with well-performed scientific quantitative studies in critical care and we make a judgment about our practice based on their recommendations. The same cannot be said of qualitative research, and its use accounts for only a small proportion of published studies in critical care.

So, I have selected papers relevant to the management of these frightening situations.

Optimising well-being: is it the pain or the hurt that matters?
