Summary

This retrospective chart review found that dysnatremia—particularly hypernatremia—occurred significantly more frequently in COVID-19 patients than in SARS-CoV-2-negative controls with respiratory illness. Hypernatremia was present in 38% of COVID-19 patients versus 8% of non-COVID controls, whilst 12% of COVID-19 patients experienced both hyponatremia and hypernatremia during admission. Over 71% of deceased COVID-19 patients developed dysnatremia compared to 57% of survivors, suggesting water and sodium balance disorders may be clinically important in COVID-19 management and prognosis.

UK applicability

These findings are directly applicable to UK clinical practice, as dysnatremia assessment and management protocols for COVID-19 patients would benefit from explicit attention to sodium balance monitoring. The association with mortality suggests UK hospital guidelines for COVID-19 care should incorporate routine plasma sodium measurement and electrolyte rebalancing protocols.

Key measures

Prevalence of hyponatremia, hypernatremia, and concurrent dysnatremia episodes; in-hospital mortality rates; χ² test for statistical significance

Outcomes reported

The study compared the occurrence of hyponatremia and hypernatremia between 193 SARS-CoV-2-positive and 138 SARS-CoV-2-negative hospitalised patients. Plasma sodium concentration abnormalities and their association with in-hospital mortality were measured.
