ABSTRACT
The aim of this study is to assess the use of high-risk medications in patients with community-acquired acute kidney injury (CA-AKI) and the differences in the characteristics and outcomes of CA-AKI based on the use of these medications. This is a retrospective audit of adults (≥35 years) with CA-AKI admitted to a large tertiary care hospital over a two-year period. We investigated the prevalence of SADMANS (sulfonylureas; angiotensin converting enzyme inhibitors; diuretics; metformin; angiotensin receptor blockers; nonsteroidal anti-inflammatory drugs; and sodium glucose co-transporter 2 inhibitors) medications use in people with CA-AKI prior to hospitalisation. Outcomes including CA-AKI severity, kidney function recovery and in-hospital mortality were examined and stratified by use of SADMANS medications. The study included 329 patients, with a mean (SD) age of 75 (12) years and a 52% proportion of females, who were hospitalised with CA-AKI. Most patients (77.5%) were taking at least one regular SADMANS medication upon admission. Overall, 40% of patients (n = 132) and 41% of those on SADMANS (n = 104) had hypovolaemia or associated symptoms such as vomiting and diarrhoea during admission. Over two-thirds (68.1%) had mild AKI on admission and patients who were taking SADMANS medications were more likely to have mild AKI. Patients on SADMANS had more comorbidities and a higher medication burden, but there were no differences in AKI severity on admission or outcomes such as length of hospitalisation, ICU admission, need for dialysis, recovery rates and mortality between the two groups. However, the high prevalence of SADMANS medications use among patients with CA-AKI indicates a potential for preventability of CA-AKI-led hospitalisations. Future studies are needed to gain better insights into the role of withholding this group of medications, especially during an acute illness.
ABSTRACT
BACKGROUND: Use of certain medications during an acute illness may put patients at an increased risk of acute kidney injury (AKI). Patients with chronic kidney disease (CKD) are at higher risk of developing superimposed AKI. The aim of this scoping review is to collate and characterise existing evidence on sick day management considerations and practices during acute illness in people with CKD. METHODS: We searched Embase, CINAHL, MEDLINE, International Pharmaceutical Abstract, Scopus, Google Scholar and grey literature sources. We followed the methodological framework for scoping reviews, while information was extracted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for scoping reviews. Findings are presented thematically. RESULTS: Ten studies and seven guidelines met the inclusion criteria. Studies were targeted at patients, general practitioners, pharmacists, and nurses. The major themes identified included development and feasibility testing of a sick day management protocol, current practice of temporary medication discontinuation, and outcomes. Most guidelines provided recommendations for sick day management largely based on expert consensus. A digital intervention was deemed highly acceptable and easy to use, whereas patient handouts were more effective when provided along with dialogue with a health professional. While there is little evidence on the impact of sick day protocols on outcomes, a single randomised trial reported no significant association between sick day protocols and change in kidney function, AKI incidents or risk of hospitalisation. CONCLUSION: The nascent literature on sick day management in patients with CKD revealed the limited available evidence to provide guidance on implementation and on outcomes. Future research needs to clarify sick day recommendations and assess their impact on clinical outcomes including prevention of superimposed AKI or hospitalisations, as well as to address barriers to implementation.
