Preventing acute kidney injury: assessing awareness to temporarily discontinue 'at-risk' medicines during acute illness in a New Zealand cohort.

AIM The objective of this research is to determine community dwelling patients' awareness of temporarily discontinuing medicines during acute illness, and the actions they would undertake when acutely unwell. METHOD Adults taking long-term oral medicines for chronic health conditions completed a four-question self-completion paper-based questionnaire collecting data requiring quantitative analysis. Recruitment occurred in six participating Hawke's Bay community pharmacies during 2017 and 2018. RESULTS One hundred and thirty people completed the survey. Seventeen (13%) recalled receiving guidance from a health professional on which medicines to stop during excessive vomiting or diarrhoea. Only three people, however, would stop their medicines. Eighteen percent (17/95) of participants aged 65 years and older were prescribed both a NSAID and either an angiotensin-converting-enzyme inhibitor (ACEi) or angiotensin-II receptor blocker (ARB); five reported receiving advice to withhold medicines. Three participants were prescribed a Triple Whammy combination; none reported being advised to withhold medicines. CONCLUSION A small proportion of the participants recalled receiving guidance to temporarily withhold medicines during acute illness; many indicated the advice would not be followed. The results indicate a degree of acute kidney injury prior (AKI) at-risk prescribing. There are opportunities to empower people to self-manage at-risk medicines during periods of acute illness.
