Diagnostic validity and solute-corrected prevalence for hyponatremia and hypernatremia among 1 813 356 admissions
The ICD-10 diagnostic codes showed low sensitivity, high specificity, and high positive predictive value for identifying hyponatremia and hypernatremia. Corrections for glucose or total protein did not affect diagnostic values but would be necessary for accurate prevalence calculation.
