Validation of ICD-10 codes used to identify the main reason for hospitalization due to hyponatremia in Sweden.

ABSTRACT:

Purpose

Hyponatremia is the most common electrolyte disorder, with potentially serious consequences. Studies validating hyponatremia used as a principal diagnosis are lacking. Studying principal diagnoses is important since it indicates the main reason for inpatient care. The aim of this study was to assess the validity of principal diagnoses of hyponatremia according to the International Classification of Diseases, tenth revision (ICD-10) in patients discharged from hospital.

Methods
