Abstract

Objective:

We sought to assess the disutility associated with diabetes in the kidney transplant population.

Methods:

We enrolled 233 kidney transplant recipients age 18–74 from a Midwestern hospital outpatient department. Recipients with multiple or multi-organ transplants, those with laboratory evidence that suggests acute cellular damage (creatinine-kinase > 200 U/L), or a diagnosis of acute renal failure or acute rejection were excluded from the analysis (n = 33). Participants health-related quality of life (HRQOL) were evaluated using the Euro-QoL-5 Dimension (EQ-5D), Health Utility Index Mark III (HUI-III), and the Short Form-6D (SF-6D), which was calculated from the generic section (SF-12) of the Kidney Disease Quality of Life 36 (KDQOL-36). We estimated health utilities associated with diabetes using general linear modeling after adjusting for demographic, socioeconomic, and clinical characteristics.

Results:

The adjusted health disutilities associated with diabetes were clinically and statistically significant: EQ-5D (Δ = 0.05; p < 0.01), HUI-III (Δ = 0.09; p < 0.01), and SF-6D (Δ = 0.04, p < 0.01). There was no difference between diabetic patients with good glycemic control (mean serum glucose <126 mg/dL in the three months prior to enrollment) and patients with poor glycemic control.

Conclusions:

Among kidney transplant patients between the ages of 18–74, non-diabetics have significantly higher HRQOL scores on the EQ-5D, HUI-III, and SF-6D compared with patients with diabetes.
