Table 3 Outcome and natremia evolution in the emergency department and during hospitalization
From: Undercorrection of hypernatremia is frequent and associated with mortality
Outcome | n = 85 |
|---|---|
All patients | |
Outcome after emergency department | |
Hospitalization | 92% |
Back to institution | 6% |
Died at emergency department | 1% |
Unknown | 1% |
In hospital mortality | 24% |
Mean time to death (days) | 5.8 ± 6 |
Hospitalized patients | n = 78 |
Natremia at admission (mmol/L) | 158 ± 8 |
On the next day (n = 59) | |
