Patient-Reported Outcomes

Patient-reported outcomes provide health care providers and researchers with important information about patients’ perspectives on the effectiveness of health care interventions and services.

The patient-reported outcomes (PRO) program focuses on the validation and utilization of person-centered measurement instruments (e.g., questionnaires delivered in paper form, online, or via a handheld device) by which people report on their perceived health outcomes, including their quality of life, symptoms, daily functioning, and aspects of physical, psychological, social, and spiritual well-being.

Program Head: Dr. Rick Sawatzky

There is growing interest in the use of PROs in the Canadian health care system to support person-centered care, practice improvement, and policy development.

PRO research at CHÉOS focuses on statistical methods for PROs, the use of PROs in clinical practice, the development and validation of PRO measurement instruments, and reviews regarding the selection and utilization of PROs.

The primary research and methodology areas our patient-reported outcomes program undertakes are:

Statistical Methods for Patient-Reported Outcomes

The overall aim of this research is to develop and implement statistical methods that will contribute to valid, reliable, and comparable patient-reported outcomes data for decision-making. Specific topics include:

  • Validity of PRO measures in heterogeneous populations
    • Differential item functioning in the SF-36 physical functioning and mental health sub-scales (Publication Link)
    • Latent variable mixture models: A promising approach for the validation of patient reported outcomes (Publication Link)
  • Methods for response shift detection and accommodation
  • Computerized adaptive testing
    • The accuracy of computerized adaptive testing in heterogeneous populations (Publication Link)
  • Symptom profiles
    • Symptom distress profile in hospitalized patients in Sweden: A cross-sectional study (Publication Link)
  • Deriving and measuring quality-adjusted life years

Electronic Patient-Reported Outcomes (e-PROs) in Clinical Practice and Decision-Making

  • Use of a Quality-of-life and Practice Support System (QPSS) in home care services for older adults (Archived Webinar)
  • The use of electronic QoL assessments to negotiate shared understandings of care (In Progress)

Integrating a Quality-of-Life Assessment and Practice Support System in Palliative Home Care

Older adults with advancing and life-limiting illnesses often have complex issues affecting their ability to function and overall quality of life (QoL). As such, a routine assessment of their health care needs and QoL is needed to ensure they are receiving the best care possible. These assessments typically include questions about the patient’s symptoms, well-being, and their experience with the care they are receiving. This information can not only improve the quality of care for by the patient, but also lessen the burden on the health care system and its providers.

Dr. Rick Sawatzky’s research investigates the use of self-reported, tablet-based QoL assessments for older adults with life-threatening illnesses in a homecare setting. Handheld electronic instruments eliminate the hassle of paper forms, and can serve as an efficient way for patients and family caregivers to make their concerns visible to health care providers. Dr. Sawatzky’s research seeks to answer two key questions: how to best integrate electronic QoL assessment for older adults in palliative homecare; and whether the routine use of these instruments improves the quality of care they receive.

This study will provide a much-needed homecare perspective to existing research in a hospital setting, and is part of a larger research initiative on the implementation of a tablet-based QoL Assessment and Practice Support System (QPSS). The results of this study will provide insight into the use of electronic QoL assessments in palliative homecare nursing, with the ultimate goal of improving care for older adults with serious, life-limiting illnesses as well as their family caregivers.

Quality of Life for Homeless and Hard-to-House Individuals (QOLHHI) Inventory

The QoLHHI Inventory is a tool that helps to measure subjective quality-of-life (QoL) in homeless or vulnerably housed individuals. Created by CHÉOS Scientists Drs. Anita Palepu, Anne Gadermann, and UBC Professor Dr. Anita Hubley, the QoLHHI is interview-based and is a comprehensive measure of QoL, and is available for researchers to use free-of-charge for research, service provision, and program evaluation purposes.

Findings from recent use of the Inventory, Content validation of a quality-of-life measure for individuals who are homeless and vulnerably housed, were presented at the 22nd Annual Conference for the International Society for Quality of Life Research (ISOQOL) in Vancouver, BC, in October 2015.
