Summary
This systematic review and meta-analysis synthesised 17 studies comprising 19,032 patients with hypernatremia to assess associations with COVID-19 outcomes. Hypernatremia was markedly associated with increased odds of mortality (OR 3.18), mechanical ventilation (OR 5.40), and prolonged hospitalisation (OR 1.97), with age identified as a significant moderator of ICU admission risk. The authors conclude that electrolyte monitoring and clinical attention to hypernatraemic COVID-19 patients is warranted.
UK applicability
These findings are relevant to UK clinical practice and hospital protocols for COVID-19 management, suggesting that serum sodium measurement and correction strategies may reduce adverse outcomes in hospitalised patients. However, applicability depends on whether UK COVID-19 patient populations exhibit similar hypernatraemia prevalence and risk profiles.
Key measures
Odds ratios for mortality, prolonged hospitalisation, mechanical ventilation, and ICU admission; meta-regression analysis examining age, sex, and comorbidities as moderators
Outcomes reported
The study examined the association between elevated serum sodium levels (hypernatremia) and adverse clinical outcomes in COVID-19 patients, including mortality, mechanical ventilation requirement, ICU admission, and prolonged hospitalisation.
