Great expectations? Pre-transplant quality of life expectations and distress after kidney transplantation: a prospective study.

Br J Health Psychol. 2014 Nov;19(4):823-38

Abstract
OBJECTIVES: Previous research suggests that prior to kidney transplantation, patients overestimate their post-transplant quality of life (QoL). The current study aimed to corroborate these findings, identify determinants of QoL overestimation, examine its association with subsequent distress, and clarify the role of optimism.
DESIGN: Prospective observational study.
METHODS: Physical, psychological, and social QoL expectations, actual QoL, and distress (GHQ-12) of participants (56% male) were prospectively assessed before (T0; n = 228) and 3 (T1; n = 149), 6 (T2; n = 146), and 12 (T3; n = 114) months after successful transplantation.
RESULTS: Patients who were treated with haemodialysis before transplantation reported greater physical QoL overestimation than those who received treatment with peritoneal dialysis. Neither physical nor social QoL overestimation at T1 was prospectively associated with increased distress at T2 or T3. The interaction between optimism and social QoL overestimation at T1 (β = -.56, p < .001) for distress at T2 was significant, with patients low in optimism experiencing more distress after QoL overestimation.
CONCLUSIONS: QoL overestimation is not associated with subsequent distress. Findings suggest that patients low in optimism are more vulnerable to distress following QoL overestimation.
STATEMENT OF CONTRIBUTION: What is already known on this subject? Kidney transplantation improves patients’ quality of life. Prior to kidney transplantation, patients overestimate the scale of this improvement. What does this study add? Quality of life overestimation is not associated with subsequent distress. When optimism is low, kidney transplant recipients experience higher distress following quality of life overestimation.

Perceived health after kidney transplantation: a cross-sectional comparison of long-term and short-term cohorts.

Transplant Proc. 2013 Jul-Aug;45(6):2184-90

Abstract
Although increased longevity of grafts has led to a growing number of long-term kidney transplant recipients, knowledge about the perceived health of these patients remains limited. A cross-sectional sample of 609 patients (60% response) was stratified into a short-term (≤1 year), midterm (>1 and ≤8 years), and long-term cohort (>8 and ≤15 years posttransplantation). Cohorts were compared for perceived health (Visual Analogue Scale of the EQ-5D), number of symptoms, and number of comorbidities by analysis of variance/covariance and multivariate regression analyses. Long-term patients reported more symptoms, (F[2, 606] = 3.09, P = .046) and more comorbidities, (F[2, 588] = 4.75, P = .009) but similar levels of perceived health, (F[2, 550] = 2.37, P > .05). Furthermore, symptoms were less influential for perceived health among long- versus short-term (z = -2.08, P = .038) or midterm cohorts (z = -2.60, P = .009). Previously identified predictors of perceived health accounted for less variance in the long-term as opposed to short-term (z = 4.30, P < .001) and midterm cohort (z = 2.07, P = .039). Despite more symptoms and comorbidities, the perceived health of long-term kidney transplant recipients was comparable to the short- and midterm, possibly due to selective survival or patient adjustment. Because kidney function and symptoms were predominantly associated with short-term perceived health, there is an urgent need to identify variables associated with long-term perceived health.
