Associations between hyponatraemia, volume depletion and the risk of falls in US hospitalised patients: a case-control study.

ABSTRACT:

Objective

We aimed to determine if abnormal laboratory values which may indicate volume depletion are associated with increased odds of experiencing a hospital-acquired fall.

Design

Matched case-control study.

Setting

Four hospitals located in the Southeast USA.

Participants

Data from 699 adult fallers and 1189 matched controls (non-fallers) were collected via chart review from 2005 to 2010. Controls were matched to cases by nursing unit, time of fall and length of stay.

Outcome measures

The primary exposures included serum sodium, blood urea nitrogen (BUN), creatinine, BUN/creatinine ratio and haematocrit. Conditional logistic regression with m:n matching was used to determine adjusted and unadjusted ORs.

Results

Serum sodium levels were strongly
