title: Temporal stability of polydipsia-hyponatremia.
abstract: We evaluated temporal stability and outcome predictors associated with polydipsia-hyponatremia (PH). Severity of PH was measured on two occasions separated by at least 1 year in 25 chronic psychiatric inpatients (24 with schizophrenia). Three-quarters of the sample had clinically evident PH on follow-up. Follow-up PH severity was significantly related to intake severity and hospitalization length. Our findings suggest that PH may be a persistent condition with specific outcome predictors.
