What is the treatment and management for patients with hypokalaemia? A critical review of the literature
Bibliographic record
Abstract
Abstract Hypokalaemia is a common electrolyte disturbance in emergency departments and hospital settings with significant clinical and prognostic implications. About 11% of ED patients present with hypokalaemia (serum potassium [K+] <3.5 mmol/L), while 1.1% have severe cases (serum K+ <2.6 mmol/L). Despite its frequency, the UK lacks unified national guidelines and standardised protocols, resulting in variable treatment practices and increased patient safety risks. This dissertation critically examines current treatment and management strategies for hypokalaemia, emphasizing individualised care, vigilant monitoring, and protocol-driven approaches. Synthesising evidence from studies published between 2014 and 2024, the review analyses existing management practices, highlights gaps in clinical guidelines, and offers insights for evidence-based care. A critical literature review was conducted using databases such as Medline, CINAHL, and Scopus. English-language articles were selected based on criteria including adult populations, primary quantitative and qualitative research, guidelines, reviews, and meta-analyses. A thematic analysis approach was employed to identify patterns in hypokalaemia management, categorising data into three themes: individualised treatment approaches, monitoring and safety, and protocol-driven management. The Newcastle-Ottawa Scale (NOS) was used to assess the quality of the included studies. Findings indicate that hypokalaemia management could benefit from more consistent protocols, as treatment decisions are influenced by clinical severity, patient-specific factors, and resource availability. Tailored approaches are crucial for vulnerable groups such as patients with heart disease, diabetes, and chronic kidney disease. Rigorous monitoring—including frequent serum K+ checks and electrocardiography (ECG)—is essential to prevent complications like overcorrection and arrhythmias. Magnesium supplementation, particularly in the presence of hypomagnesemia, appears beneficial in optimising K+ replacement. Protocol-driven methods, including automated systems (e.g., the GRIP-II algorithm) and sliding-scale dosing protocols, show promise in improving consistency and reducing clinical errors. However, the absence of national guidelines in the UK fosters inconsistency, with empirical rather than evidence-based practices prevailing. Integrating individualised treatment with thorough monitoring and automated protocols may lead to more consistent outcomes, reduced complications, and better resource allocation in emergency settings. Thus, coordinated efforts among clinicians and policymakers are essential for implementing unified, evidence-based guidelines for optimal hypokalaemia management.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
