SF36 Quality of Life and Mortality across Different Levels of Serum Albumin in Patients with Hemodialysis

Patients on hemodialysis (HD) generally display a significant decrease in the quality of life owing to comorbidities, malnutrition, and inflammation.
In this multicenter prospective study, the SF36 (short form with 36 questions scored between 0 and 100) and relevant demographic data and comorbidities (charlson comorbidity index); nutritional factors, and C-reactive protein (CRP) were evaluated in 416 HD patients in September 2012. Hospitalization and mortality were assessed in a median of a 28 month follow-up.
The SF36 score in survived patients was 53.6 ± 19.3 versus 41.6 ± 22.4 in the non-survived patients (P 3.60 - 3.85, > 3.85 - 4.00, > 4.00 - 4.20, > 4.20 (reference) g/dL was respectively 3.69 (1.98 - 6.89), 2.08 (1.10 - 3.94), 1.91 (0.97 - 3.85), 1.10 (0.76 - 1.49). Serum albumin revealed a strong association with mortality such that hazard ratio for every 1 g/dL decrease in serum albumin was 6.28 (95% CI: 3.80 - 10.42; P
