Observational StudyHigh serum potassium level is associated with successful electrical cardioversion for new-onset atrial fibrillation in the intensive care unit: A retrospective observational study.
Electrical cardioversion (ECV) is a potentially life-saving treatment for haemodynamically unstable new-onset atrial fibrillation (AF); however, its efficacy is unsatisfactory. We aimed to elucidate the factors associated with successful ECV and prognosis in patients with AF. This retrospective observational study was conducted in two mixed intensive care units (ICUs) in a university hospital. ⋯ ECV was successful in 48% of patients with new-onset AF developed in the ICU. A serum potassium level ≥3.8 mol/L was independently associated with successful ECV, and sinus rhythm maintained until ICU discharge was independently associated with ICU survival. These results suggested that maintaining a high serum potassium level may be important when considering the effectiveness of ECV for AF in the ICU.

The effect of guideline implementation on discharge analgesia prescribing (two years on).
The provision of appropriate discharge analgesia can be challenging and is often prescribed by some of the most junior members of the medical team. Opioid abuse has been considered a growing public health crisis and physician overprescribing is a major contributor. In 2015 an initial audit of discharge analgesia at the Royal Perth Hospital led to the development of discharge analgesia guidelines. ⋯ The quantity of oxycodone IR given on discharge complied with quantity guidelines in only 56% of cases. Overall there has been a significant and sustained improvement in appropriateness of discharge analgesia prescribing since 2015, though the results from 2017 show less compliance than 2016 and that achieving compliance with quantity guidelines is an ongoing challenge. This demonstrates the challenge of obtaining high adherence to guidelines over a longer time period.
