Overview
Hyponatremia is the most common electrolyte disorder. Its frequency is higher in females, the elderly, and in patients who are hospitalized. The incidence of hyponatremia depends largely on the patient population. A hospital incidence of 15–30% is common.
Epidemiology and Demographics
Incidence
- Hyponatremia is the most common electrolyte disturbances in clinical practice, occurring in 15%-30% of hospitalized patients ( acutely or chronically) [1], 1-2% of this patients present with severe hyponatremia (serum sodium < 125 mEq/L) .
- Post-operative hyponatremia develops in 4.4% of patients within 1st week of surgery [2] .
Prevalence
- Prevalence of hyponatremia is 1720 per 100,000 in the U.S. population [3] .
- Nearly 7.7 % of patients who are visited in outpatients clinics are hyponatremic.
- Hyponatremia is seen in up to 27% of patients with heart failure (HF) [4] .
- Approximately 50% of patients with cirhosis and ascites are found to be hyponatremic [5] .
- Hyponatremia has been reported in up to 30% of elderly patients in nursing homes and is also present in approximately 30% of depressed patients on selective serotonin reuptake inhibitors [6] .
Case-fatality rate/Mortality rate
- Over the period of 1999-2006, mortality rate was 11% and 4% for hyponatremic and normonatremia subjects, respectively [7] .
- There is an increased risk of mortality in patients with congestive heart failure, renal failure and cirrhosis.
- Hyponatremia is associated with worse clinical outcome, inpatients or outpatients.
- The underlying illness that is associated with hyponatremia has more correlation with mortality rate rather than severity of hyponatremia [8].
Age
- Age over 30 is related to increased overall incident of hyponatremia especially hospital acquired hyponatremia. The association is stronger even with increasing severity of hyponatremia [9] .
- In elderly patients, lower body weight is associated with increased risk of drug-induced hyponatremia [10] .
Race
- There is no racial predilection to [disease name].
Gender
- Female sex is considered a risk factor for psychotropic and diuretic-induced hyponatremia [11] .
- Severe hyponatremia occurs more frequently in women because of lower body weight.
Region
- The majority of [disease name] cases are reported in [geographical region].
