The Influence of Alcohol Abuse History on the Differential, Longitudinal Patterns of Mental and Physical Quality of Life Following Liver Transplantation
ABSTRACT This prospective, longitudinal study investigated change in physical and mental health quality of life (QoL) in a sample of 65 end-stage liver disease patients before and after liver transplantation. Physical and mental health QoL were assessed using the SF-36 Physical Health Summary and Mental Health Summary, respectively. Baseline data were collected prior to transplant and follow-up data were collected at 1 and 6 months after transplantation. Repeated-measures analysis of variance results indicate that physical QoL did not improve significantly between baseline and 1-month follow-up (F = .031, P = .860) but did between 1- and 6-month follow-up (F = 20.873, P < .001). Significant between-subject effects suggested attenuated improvement for patients with alcohol abuse histories (F = 6.213, P = .017). Physical QoL did not improve between 1- and 6-month follow-up for patients with alcohol abuse history (t((13)) = -1.074, P = .112). By contrast, mental health QoL improved significantly between baseline and 1-month follow-up (F = 13.840, P < .001), but not between 1- and 6-month follow-up (F = .750, P = .391). No significant differences were found on the Mental Health Summary index based on alcohol abuse history for either time period. Post hoc multivariate analysis of variance results suggested worse functioning (F = 2.674, P = .013) for individuals with alcohol abuse history on SF-36 Physical Functioning (F = 5.55, P = .021), Body Pain (F = 13.578, P < .001), Vitality (F = 4.337, P = .040), and Social Functioning (F = 10.50, P = .002) subscales. For liver transplant patients, improvements in psychosocial functioning and QoL precede improvements in physical QoL. Attenuated physical QoL improvements for patients with alcohol abuse histories are related to greater pain and physical deficits.

ABSTRACT: Patient-reported outcomes are important to consider when the relative success of liver transplantation (LT) is being evaluated. Our primary objective was to examine the expectations for LT and the criteria for its success across 4 domains of functioning (pain, fatigue, emotional distress, and interference with daily activities) from the perspective of patients who were wait-listed for LT. One hundred four adult patients with a mean wait-list time of 16.5 ± 13 months completed a semistructured interview with a modified version of the Patient-Centered Outcomes Questionnaire (PCOQ). The patients reported moderate usual levels of pain, fatigue, emotional distress, and interference with daily activities (mean rating range = 3.8-6.2), and they attached great importance to improvements in these domains after LT (mean rating range = 7.3-8.0). Patients considered a mean reduction in pain of 33% to be a successful LT outcome. A reduction in fatigue of 56%, a reduction in emotional distress of 44%, and a reduction in interference with daily activities of 54% represented successful LT across these domains. Patients with more severe illness had higher expectations for fatigue (r = -0.30, P = 0.002) and interference with daily activities (r = -0.24, P = 0.015). Cluster and correlational analyses provided support for the validity of the PCOQ with LT patients. Our findings underscore the importance and value of using patient-centered assessments to better understand the ways in which patients prioritize LT outcomes and define transplantation success. Patient-centered assessments have the potential to facilitate provider-patient communication by helping patients to prioritize their goals for LT and make informed choices on the basis of those priorities.Liver Transplantation 11/2011; 17(11):1309-17.

ABSTRACT: In patients with alcohol dependence, health-related quality of life (QOL) is reduced compared with that of a normal healthy population. The objective of the current analysis was to describe the evolution of health-related QOL in adults with alcohol dependence during a 24-month period after initial assessment for alcohol-related treatment in a routine practice setting, and its relation to drinking pattern which was evaluated across clusters based on the predominant pattern of alcohol use, set against the influence of baseline variables METHODS: The Medical Outcomes Study 36-Item Short-Form Survey (MOS-SF-36) was used to measure QOL at baseline and quarterly for 2 years among participants in CONTROL, a prospective observational study of patients initiating treatment for alcohol dependence. The sample consisted of 160 adults with alcohol dependence (65.6% males) with a mean (SD) age of 45.6 (12.0) years. Alcohol use data were collected using TimeLine Follow-Back. Based on the participant's reported alcohol use, three clusters were identified: 52 (32.5%) mostly abstainers, 64 (40.0%) mostly moderate drinkers and 44 (27.5%) mostly heavy drinkers. Mixed-effect linear regression analysis was used to identify factors that were potentially associated with the mental and physical summary MOS-SF-36 scores at each time point.Alcohol and alcoholism (Oxford, Oxfordshire).
