Economic Analysis of Early vs Delayed Therapy in Newly Diagnosed Asymptomatic High-Risk Patients With Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma:

NCT05371808 · Status: RECRUITING · Type: OBSERVATIONAL · Enrollment: 247

Last updated 2026-05-06

No results posted yet for this study

Summary

Utilization data will be collected from all patients entered on the trial at Canadian centres from the time of registration until death, removal from study, or completion of 10 years of follow-up.

Protocol-specified health care utilization will be collected within trial case report forms, and will include study visits, radiographic assessments, laboratory investigations, and treatment administration.

Resource utilization data collection will be supplemented by a self-administered resource utilization form (Stanford SMRC) to document non-protocol specified utilization. This will include hospitalizations (including days in hospital), emergency room visits, and non-protocol specified ambulatory visits.

Conditions

Interventions

OTHER

EQ-5D-5L Instrument

This instrument is a measure of health status for use in evaluating health and healthcare.

OTHER

Work Productivity and Daily Activity Impairment (WPAI) survey

The questionnaire includes three open-ended questions that determines: 1) hours absent from work due to health problems; 2) hours absent from work due to other reasons; and (3) hours actually worked over the past 30 days. Additional questions ask about the impact of health problems on work productivity and daily activities and are scored along a vertical visual analog scale. The WPAI provides estimates on absenteeism, presenteeism, global measures of lost productivity (absenteeism+presenteeism) and daily activity impairment (impaired ability to perform non-work activities including work around the house, child care, exercise, studying, and leisure activities)

OTHER

Resource Utilization Form (SMRC)

Resource utilization data collection will be supplemented by a self-administered resource utilization form (Stanford SMRC) to document non-protocol specified utilization. This will include hospitalizations (including days in hospital), emergency room visits, and non-protocol specified ambulatory visits.
