The construct validity of the health utilities index mark 3 in assessing health status in lung transplantation.

PURPOSE: To assess the cross-sectional construct validity of the Health Utilities Index Mark 3 (HUI3) in lung transplantation. METHODS: Two hundred and thirteen patients (103 pre-transplant and 110 post-transplant) with mean age 53 years old (SD 13) were recruited during a randomized controlled clinical trial at the out-patient clinic in a tertiary institution. At baseline, patients self-completed measures that included the HUI3, EuroQol EQ-5D, Hospital Anxiety and Depression Scale (HADS) and socio-demographic questionnaire. Six-minute walk test scores and forced expiratory volume in 1 second data were collected from patient's medical records. A priori hypotheses were formulated by members of the transplant team about the expected degree of association between the measures. Correlation coefficients of < 0.1 were considered as negligible, 0.1 to < 0.3 as small, 0.3 to < 0.5 as medium, and ≥ 0.5 as large. RESULTS: Of the ninety predictions made, forty three were correct but in 31 the correlation was slightly lower than predicted and in 7 the correlations were much higher than predicted. In 48% of the cases, predicted and observed associations were in agreement. Predictions of associations were off by one category in 42% of the cases; in 10% of the cases the predictions were off by two categories. CONCLUSIONS: This is the first study providing evidence of cross-sectional construct validity of HUI3 in lung transplantation. Results indicate that the HUI3 was able to capture the burden of lung disease before transplantation and that post-transplant patients enjoyed higher health-related quality of life than pre-transplant patients.

The use of patient-reported outcomes becomes standard practice in the routine clinical care of lung-heart transplant patients.

OBJECTIVE: To assess the use of patient-reported outcome (PROs) measures in the routine clinical care of lung-heart transplant patients. We assessed whether the addition of PROs in routine clinical care affected the duration of the consultation and patient's and clinician's views. METHOD: Consecutive lung-heart transplant patients visiting the outpatient clinic, University of Alberta Hospital, completed the Chronic Respiratory Questionnaire (CRQ) and the Health Utilities Index (HUI) on touchscreen computers. Information on the patient's responses was made available to the members of the transplant team prior to the encounter with the patient. The duration of clinical encounters was noted. At the end of every visit, clinicians completed a questionnaire on the usefulness of having PRO information available. After 6 months patients completed a survey of their experiences. RESULTS: The final patient sample consisted of 172 patients with a mean (SD) age of 52 (13.3) years old; 47% were female; 68% were organ recipients and 32% candidates. The transplant team, comprising four pulmunologists, two nurses, and one pharmacist had an average of 9 years of practical experience in pulmunology. The mean duration of patient-clinician encounters in minutes was 15.15 (4.52). Ninety-eight percent of patients indicated that they would be happy to complete the CRQ and HUI at every clinic visit. Ninety-one percent of the assessments completed by clinicians showed complete satisfaction with the use of PROs in routine practice. Further, the clinicians developed guidelines for the use of PRO information in clinical practice. CONCLUSIONS: The incorporation of PRO measures in the routine clinical care of lung-heart transplant patients resulted in a reduction of the duration of patient-clinician encounters. The experience was well accepted by patients and clinicians. We conclude that the routine use of PROs in lung-heart transplant patients has become standard practice.
