Hyponatremia is the most common electrolyte disorder encountered across multiple medical specialties and is associated with increased morbidity and mortality. Management of hyponatremia requires precise correction of serum sodium levels. Given the complexity of treatment, the involvement of nephrologists may play a critical role in optimizing outcomes. This study aimed to evaluate the association between early nephrology consultation (NC) and mortality in patients with severe hyponatremia.
This retrospective cohort study included patients with severe hyponatremia (serum sodium ≤120 mEq/L) identified at admission or during hospitalization in two tertiary care centers between January 2014 and June 2024. NC was defined as any therapeutic involvement by nephrologists within 24 hours of diagnosis. The primary outcome was the association of NC with in-hospital and 30-day mortality, evaluated using logistic regression with inverse probability of treatment weighting based on propensity scores.
Of the 942 patients included in the analysis, 342 (36%) received NC and 600 (64%) did not. The median (interquartile range) age was 73 (62–82) years, 430 (46%) were female, and the median serum sodium level was 118 (116–119) mEq/L. In the NC group, in-hospital mortality (10% vs. 23%) and 30-day mortality (8% vs. 18%) were significantly lower, and the length of hospital stay was shorter (14 vs. 19 days) (all P < 0.01). In weighted logistic regression analyses, NC remained significantly associated with reduced odds of in-hospital mortality (odds ratio [OR], 0.55; 95% confidence interval [CI], 0.37–0.83) and 30-day mortality (OR, 0.62; 95% CI, 0.40–0.96). Osmotic demyelination syndrome occurred in three patients, with no significant difference between groups (P = 0.27).
Early nephrology consultation was significantly associated with lower in-hospital and 30-day mortality in patients with severe hyponatremia, highlighting the crucial role of nephrologists and the need for interdisciplinary collaboration in management of severe hyponatremia.
