The initial IV diuretic dose administered in the emergency department was considered adequate if it was 1.5 times the outpatient oral loop diuretic dose given as an IV bolus or was IV furosemide 80 mg or the equivalent for diuretic-naive patients.
Adequate dosing and male sex were associated with significantly shorter lengths of stay, and systolic blood pressure less than 110 mm Hg, higher serum creatinine levels, and higher body weight at admission were associated with longer lengths of stay (P<0.05 for all).
Both low blood pressure and high serum creatinine levels were associated with the underdosing of diuretics because, Fearon-Clarke said, the clinicians were afraid of making the patients with these characteristics worse.
