Fluid Imbalance Is Associated with More Severe Sepsis Hospitalizations

Following Dexur's examination of the length of stay (LOS) in sepsis patients in Mississippi, analysts examined how fluid imbalance relates to case mix. CMS divides sepsis patients into three diagnosis-related groups:

In more severe diagnosis-related groups, more patients have a fluid imbalance, and length of stay is longer. DRG and LOS both measure how severe a patient's condition is, and fluid imbalance correlates with both of them.

Average hospital in this groupSepsis without major complications/ comorbidities (DRG 872)Sepsis with major complications/ comorbidities (DRG 871)Sesis with mechanical ventilation (DRG 870)
% of patients with fluid imbalance17%25%44%
Average length of stay (days)5.0 days6.9 days14.6 days

Within each hospital, a greater percentage of DRG 870 patients have a fluid imbalance, and DRG 870 patients average longer lengths of stay. These figures vary more widely within DRG 870 than in the other two DRGs. These differences may reflect different mechanical ventilation practices at different hospitals or patient populations with differing severities within DRG 870.

Fluid Imbalance and Diagnosis-Related Group in Sepsis Patients

Patients with fluid imbalance were more likely to be on mechanical ventilation than patients without fluid imbalance. The average odds ratio was 1.57. This indicates that patients with fluid imbalance were about half again as likely to be on mechanical ventilation as patients without fluid imbalance. The highest odds ratio was 2.67 at Magnolia Health Center (Corinth, MS), and the lowest 0.76 at Anderson Regional Medical Center (Meridian, MS).

A 2005 New England Journal of Medicine study by Wiedemann et. al found that conservative fluid management can improve lung function and reduce the necessary duration of mechanical ventilation.
