Trial Outcomes & Findings for Using Health-related Quality of Life (HRQL) in Routine Clinical Care (NCT NCT00457301)

NCT ID: NCT00457301

Last Updated: 2020-04-01

Results Overview

Each clinician-patient encounter was audio tape-recorded. The content of the tape-recordings was examined and results recorded on the communication form by three blinded raters. This form tallies the number of issues discussed. The number of issues is summed to produce a communication score. The issues discussed included health attributes included in the HUI2 and HUI3: ambulation, self-care, anxiety, depression, cognitive problems, pain (type and frequency), vision, hearing speech and dexterity problems.

Participant Flow

The recruitment started July 2005. Patients were recruited at the out patient clinic University of Alberta Hospital.

Pre-transplant patients were censored out of the study once they had the lung transplant.

PRIMARY outcome

Timeframe: Baseline and end of study (6 months)

Population: Traditional analysis of covariance, ANCOVA was conducted to explore the difference between control and intervention groups at 6 months adjusting for baseline scores and transplant status. ITT was conducted and missing values were imputed using the LOCF.

Each clinician-patient encounter was audio tape-recorded. The content of the tape-recordings was examined and results recorded on the communication form by three blinded raters. This form tallies the number of issues discussed. The number of issues is summed to produce a communication score. The issues discussed included health attributes included in the HUI2 and HUI3: ambulation, self-care, anxiety, depression, cognitive problems, pain (type and frequency), vision, hearing speech and dexterity problems.

PRIMARY outcome

Timeframe: At baseline and end of study (6 months)

Population: Analysis was conducted using ITT, with 47 observations carried forward.

Changes in clinical management were recorded in the chart review form. The number of referrals to other healthcare providers, tests ordered (X-rays, blood test, bronchoscopies) and changes in medication (reduction or increase dosage, addition or discontinuation) were summed to produce the management composite.

PRIMARY outcome

Timeframe: At baseline and end of study (6 months).

Population: To compare two independent means for a parallel trial design, 100 patients in each group were needed to detect a clinically important difference (CID) in EQ-5D index score (CID = 0.10, SD = 0.25) with a 5% probability of Type I error, two-sided-test and 80% power. ITT was conducted for 213 recruited patients. 47 records were imputed using LOCF.

Generic preference-based measure. EQ-5D consists of two sections: a 100-point visual analog scale (VAS) and a descriptive system that contains five attributes (mobility, self-care, usual activities, pain or discomfort, and anxiety or depression) with three levels per attribute ("no problem", "some problems" and "extreme problems").Using the US scoring function EQ-5D index scores range from -0.11 (all-worst health state, worse than dead), to 0.00 (dead) to 1.00 (perfect health). The EQ-5D is easy to complete, valid and reliable.

SECONDARY outcome

Timeframe: Baseline and end of study (6 months)

Population: 47 observation were imputed by LOCF and analyzed as ITT.

HADS is a self-complete mental health measure. The scale consists of 14 items, seven of which assess anxiety and seven which assess depression. Each item is on a four point scale and the scores are added to give a total ranging from 0 to 21 for anxiety and 0 to 21 for depression. Higher scores indicate more severe anxiety or depression. A cut-point of 8 or 9 indicates mild burden for the two scales; 11 or 12 indicates severe . All the patients completed HADS at baseline and at the end of the study.
