Objective:

To evaluate the association between the rate of sodium correction and the risk of 90-day death or delayed neurologic events in hospitalized patients with severe hyponatremia (serum sodium levels of 120 mEq/L or lower).

Key Findings:
  • The primary outcome occurred in 21% of patients, with 90-day death in 18% and delayed neurologic events in 4%.
  • Medium and fast correction rates were linked to a 5.6 and 9.0 percentage point reduction in the adjusted risk of the primary outcome, respectively.
  • Risk differences increased with higher predicted risk, although risk ratios remained similar.
Interpretation:

The findings suggest that faster sodium correction may reduce mortality and neurologic complications, challenging current treatment guidelines that recommend slower correction to prevent osmotic demyelination syndrome.

Limitations:
  • Residual confounding may affect the results.
  • Outcome ascertainment relied on diagnostic codes, which could introduce bias.
  • The observational nature of the study may limit causal inferences.
Conclusion:

The study advocates for a reexamination of treatment guidelines for severe hyponatremia to permit faster sodium correction, as supported by multiple studies with similar conclusions, highlighting the need for updated clinical practices.
