Psychological distress in patients presenting for initial renal transplant evaluation.

The comorbidity of psychological disorders with end-stage renal disease (ESRD) presents challenges for renal transplantation, including increased likelihood of medication noncompliance and poorer quality of life. Estimates of rates and severity of affective and anxiety disorders have varied significantly across studies of renal transplant patients, possibly due in part to variation in the methodology and timing of evaluations. To this point, few researchers have examined the psychological condition of patients who are newly referred for renal transplantation. This study examined rates of psychological distress using the Patient Health Questionnaire (PHQ) in a sample of 518 ESRD patients at the specific time point of first contact with the transplant center. In this sample, 15.1% of patients endorsed symptoms consistent with a depressive condition and 7.6% of patients endorsed an anxiety condition. These rates were lower than expected, which may be due to decreased distress in this sample, selection biases, or underreporting of symptoms due to patients' motivation to present themselves positively.
