 The relationship between Serum creatinine with length of hospital stay and mortality in heart failure patients     Zeighami Mohammadi SH [1] *, Asgharzadeh Haghighi S [2]     Received: 22 Jan, 2011 Accepted: 23 Apr, 2011  Abstract Background & Aims: Despite advances in the treatment of heart failure over the past decade, the prognosis remains poor. Impaired renal function is associated with poor outcomes among heart failure patients. The aim of this study was to determine the relationship between Serum creatinine with length of hospital stay and mortality in heart failure patients. Materials & Methods: This is a descriptive retrospective study that reviewed 263 medical records of heart failure patient's during 2002-2008 with a discharge diagnosis of heart failure. Demographic, laboratory, and echocardiography data were reviewed from medical records. In this study patients with impaired renal function were those with increased serum creatinine >1.5 mg/dl. The data were analyzed by descriptive statistics such as frequency distribution, mean, standard deviation, independent group test, Chi-square, and ANOVA. Results: The findings indicated that in 30.4% of patients serum creatinine level was < 1.5 mg/dl. Mean serum creatinine on admission was 1.45±0.67 mg/dL. Mortality occurred in 4.6% of patients. There was relationship between an increase in serum creatinine level (>1.5 mg/dl) and death during hospitalization (p=0.005). There was statistically significant difference in mean of serum creatinine levels between 2 groups of the alive (1.42±0.63) and dead (2.22±1.07) heart failure patients (p=0/000). And there was an association between mean length of hospital stay in patient with serum creatinine levels 1.5 mg/dl. (p=0.027) Conclusion: The results of this study show that the presence of serum creatinine level of < 1.5 mg/dl on admission was associated with prolonged length of hospital stay and increased in-hospital mortality Keywords: Serum creatinine, Heart failure, Length of hospital stay, Mortality    Address : Faculty of Nursing and midwifery, Islamic Azad University of Karaj, Iran   Tel : +98 9125680679   Email : zeighami@kiau.ac.ir   [1] Instructor of Nursing &Midwifery, Karaj Islamic Azad University, Karaj, Iran(Corresponding Author)   [2] BS in Nursing, Alborz Hospital, Karaj, Iran
