    More qualitative research needed to determine physician perceptions on AKI

    Dear Editor,

    We agree with Shah et al. that caring for patients with acute kidney injury (AKI) is complicated, particularly when it comes to medication management (1). It is important to remember that AKI is a heterogenous condition with multiple etiologies and different degrees of severity. In some cases then, prioritization of other chronic diseases over AKI may be reasonable and even beneficial for patients.

    On this background, we would caution against the conclusion that physicians view AKI as a low priority concern. More qualitative research is needed first to understand physician experiences with AKI during both the inpatient and outpatient setting. This information is necessary to develop and support the use of quality improvement tools for patients with AKI, such as the medication checklists referenced by Shah et al (2).

    Dear Editor,

    We have read with great interest the article “What insights do patients and caregivers have on acute kidney injury and post-hospitalisation care? A single-center qualitative study from Toronto, Canada” by Silver et al.

    The article sheds light on the fact that most of its participants prioritised chronic conditions that ‘progress over time’ over AKI. These co-morbidities often include heart failure, hypertension and Type 2 diabetes mellitus, which are treated with non-steroidal anti-inflammatory drugs, diuretics and metformin respectively( 1). There is considerable data that these drugs are nephrotoxic and should therefore, be deprescribed or temporarily with-held or dose-adjusted in patients with AKI.

    However, from unpublished research at our hospital, there is often reluctance to stop these drugs, suggesting that this misconception may be shared by physicians as well. As this is a common clinical problem with considerable morbidity, Think Kidneys Campaign (NHS collaboration of various trusts) have developed a checklist for medication optimization in patients with AKI (2), but its use is sparse at least from our experience.

    Studies have shown that in-hospital mortality due to AKI far exceeds that due to these long-standing, chronic conditions. In a large nation-based study, in-hospital mortality of AKI was found to be 12.32% (3), with an increase in number of absolute deaths from 2001 to 2011. This is in contrast to the 3% in-...
