ABSTRACT The purpose of this study was to evaluate the reliability, validity, and responsiveness to change of the Health Utilities Index Mark-3 (HUI-3) in heart failure (HF) for use in cost-effectiveness studies.
Two hundred eleven patients with HF recruited from outpatient clinics were enrolled; 165 completed the 26-week study. Patients completed 4 health-related quality of life questionnaires (baseline and 4, 8, and 26 weeks), including the HUI-3, the Medical Outcomes Study Short-form 12 (SF-12), the Minnesota Living with Heart Failure Questionnaire (LHFQ), and the Chronic Heart Failure Questionnaire (CHQ). The HUI-3 indicated moderate or fair health-related quality of life overall; the attributes most impaired were pain, ambulation, cognition, and emotion. Internal consistency reliability (Cronbach's alpha = 0.51) was low and test-retest reliability (intraclass correlation coefficient = 0.68) was adequate. The HUI-3 total score was significantly associated with the SF-12, LHFQ, and CHQ total scores. It discriminated among patients with varying New York Heart Association class (P < .001) and varying perceived health (P < .001). The HUI-3 was less responsive to perceived change in health condition than the LHFQ or the CHQ.
The HUI-3 demonstrated satisfactory reliability and validity in this sample supporting its use in cost-effectiveness studies.

    ABSTRACT: The HEALTH UTILITIES INDEX(®) (HUI(®)) is a family of systems designed to measure utility scores of health-related quality of life for comprehensive health states. There are two current HUI systems: HUI2 and HUI3. Since no Thai version of self-administered HUI was available, the study objective was to translate and test the psychometric properties of the HUI self-complete Thai-language questionnaire in terms of practicality, reliability, validity and responsiveness. A convenience sample of 216 outpatients with ischemic heart disease (IHD) was selected. Mean age was 60.3 ± 7.2 (range 37-77) and 37.2 % were males. The floor and ceiling effects of the total scores for both HUI were <15 %. The intraclass correlation coefficients were from moderate to high for all attributes and total scores. The correlations of HUI2 and HUI3 when compared with the EQ-5D and MacNew global scores were high (Spearman's rho > 0.5, P < 0.001). Discriminant validity was proved among three groups of different specific activity scale classes (P < 0.001). The effect size was the highest (0.92) in the patients reporting worsened health status assessed by the HUI2. In conclusion, both of the HUIs demonstrated conditionally satisfactory psychometric properties in the patients with IHD.

    ABSTRACT: Manual wheelchairs (MWCs) can improve mobility and social participation for individuals who experience difficulty walking; however, older adults receive little training for wheelchair use. The Wheelchair Self-Efficacy Enhanced for Use (WheelSeeU) research program provides peer-led training that may positively influence wheelchair use while reducing clinician burden. The purpose of this study is to evaluate the feasibility and clinical outcomes of WheelSeeU. A randomized control trial (RCT) recruits and randomly assigns 40 MWC users (55+ years). Feasibility indicators assessing process, resource, management, and treatment issues are measured, and clinical outcomes (wheelchair skills, safety, confidence, mobility, social participation, quality of life, health utility) are collected at three time points. WheelSeeU provides an innovative approach for teaching wheelchair skills to an aging population that may improve wheelchair use and decrease clinician burden. Since RCTs are expensive and challenging in rehabilitation, establishing feasibility prior to larger effectiveness trials is prudent.

    ABSTRACT: Background. Manual wheelchairs (MWCs) can improve mobility and social participation for individuals who experience difficulty walking; however, older adults receive little training for wheelchair use. The Wheelchair Self-Efficacy Enhanced for Use (VVheelSeeU) research program provides peer-led training that may positively influence wheelchair use while reducing clinician burden. Purpose. The purpose of this study is to evaluate the feasibility and clinical outcomes of WheelSeeU. Method. A randomized control trial (RCT) recruits and randomly assigns 40 MWC users (55+ years). Feasibility indicators assessing process, resource, management, and treatment issues are measured, and clinical outcomes (wheelchair skills, safety, confidence, mobility, social participation, quality of life, health utility) are collected at three time points. Implications. WheelSeeU provides an innovative approach for teaching wheelchair skills to an aging population that may improve wheelchair use and decrease clinician burden. Since RCTs are expensive and challenging in rehabilitation, establishing feasibility prior to larger effectiveness trials is prudent.
