APERSU Research Agenda

The scientific advisory committee identified four key areas of research that will define APERSU’s research agenda.

  • Applications of PROMs in clinical practice (e.g., decision aids, patient engagement, patient management, decision making, patients and clinicians perspective, clinical and cost effectiveness of PROMs)
  • Applications of PROMs in health systems (e.g., routine outcome measurement, quality management, quality improvement and performance, international comparisons)
  • Understanding of PROMs scores (e.g., minimal clinical important difference, measurement properties, comparisons across PROMs measures)
  • Enhancing the quality of PROMs Use (e.g., methods of data collection and presentation, methods of repeated measurements, usefulness of PROMs in special groups, response shift, case mix adjustment, knowledge transfer, translation, and utilization)

Current Projects

Properties of the EQ-5D-5L in the Canadian Population: Minimal Important Difference and Comparative Performance with other Measures in Large Scale Health Applications:
This program of research has two general aims: 1) to compare the measurement properties of the EQ-5D instruments (3- and 5-level) with other generic and disease-specific measures of health status and health-related quality of life, with particular attention to the individual dimensions of the EQ-5D; and 2) to generate estimates for a minimal important difference (MID) for the EQ-5D-5L index score.

Evaluation of routinely Measured PATient reported outcomes in HemodialYsis care (“EMPATHY”) Trial: This project aims to determine the effects of routine measurement and reporting to care providers of patient-reported outcome measures (PROMs) namely the modified Edmonton Symptom Assessment Scale – renal (mESASr) and/or the EQ-5D-5L on patient reported experience, particularly patient-clinician communication, for patients with chronic kidney disease (CKD) undergoing hemodialysis. The EMPATHY Trial will be a large, multi-center cluster randomized trial, involving up to 80 dialysis units in Ontario, Alberta and BC. The EMPATHY Trial is one project under the umbrella of a large, pan-Canadian research network known as CAN-SOLVE CKD.

The use and measurement properties of EQ-5D in vulnerable populations: A systematic review of the literature: The objective of this review is to identify, summarize and appraise the literature on the use and measurement properties of EQ-5D instruments in socially vulnerable populations, i.e. populations who are at risk of adverse health outcomes due to the socioeconomic environment and resources; including but not limited to homelessness, substance abuse among others.

PROMs in Primary Care Networks in Alberta: An end-user perspective: APERSU’s team collaborated with the Primary Care Measurement Capacity Initiative (MCI) group led by Dr. Scott Oddie with Alberta Health Services, on a project that explored the use of PROMs in primary care networks (PCNs) in Alberta, and identified the facilitators and barriers to PROMs implementation in this setting.The scientific advisory committee identified four key areas of research that will define APERSU’s research agenda.

  • Applications of PROMs in clinical practice (e.g., decision aids, patient engagement, patient management, decision making, patients and clinicians perspective, clinical and cost effectiveness of PROMs)
  • Applications of PROMs in health systems (e.g., routine outcome measurement, quality management, quality improvement and performance, international comparisons)
  • Understanding of PROMs scores (e.g., minimal clinical important difference, measurement properties, comparisons across PROMs measures)
  • Enhancing the quality of PROMs Use (e.g., methods of data collection and presentation, methods of repeated measurements, usefulness of PROMs in special groups, response shift, case mix adjustment, knowledge transfer, translation, and utilization)

Research Highlights

Xuejing (Jennifer) Jin, Fatima Al Sayah, Arto Ohinmaa, Deborah A. Marshall, Christopher Smith, Jeffrey A. Johnson

Clinical Orthopaedics and Related Research (CORR) July 2019, 477:1632-1644.

The EQ-5D has been widely using in measuring health-related quality of life (HRQL) of patients following joint arthroplasty, especially in registry programs. Previous studies indicated that the ceiling effect of the three-level EQ-5D (EQ-5D-3L) limits its application in joint arthroplasty. The five-level EQ-5D (EQ-5D-5L) was developed by adding two response levels to each dimension to improve measurement properties of the instrument; however, in joint arthroplasty field, evidence that supports the EQ-5D-5L is superior to the 3L version is limited.

In this study, Jin and colleagues examined and compared the performance of the EQ-5D-3L and EQ-5D-5L among patients awaiting total hip (THA) or knee (TKA) arthroplasty using data from the Alberta Bone and Joint Health Data Repository, which recorded information on all patients receiving elective hip or knee replacements in Alberta since 2010.

The study showed that, compared to the 3L version, the EQ-5D-5L had better measurement properties in terms of response distribution, construct validity, and ability to discriminate between patients with different severity levels of health problems, especially in mobility (a key health aspect or outcome in these patients).

Jin concluded, “the EQ-5D-5L is more appropriate for measuring HRQL of patients awaiting THA and TKA than the EQ-5D-3L.” The findings “support the use of the EQ-5D-5L for more accurate measurement of HRQL in clinical research and routine application among these patients.”

Following the publication, the Clinical Orthopaedics and Related Research journal published a commentary that summarized the importance and limitations of collecting patient-reported outcome measures (PROMs) in hip and knee replacement. The commentary endorsed the application of the EQ-5D in economic evaluations of hip and knee interventions, and highlighted the demand of minimally important difference (MID) in this field. Additionally, it recommended establishing public searchable databases, and exploring the use of pre-surgery PROMs to screen patients or predict prognosis.

MDM Policy and Practice 2018 (in press)

Anxiety and depressive symptoms are highly prevalent in chronic disease patients, including those with type 2 diabetes. These symptoms, often undiagnosed and untreated, adversely impact diabetes management and outcomes.

In this study, Al Sayah and colleagues examined the performance of two of the most commonly used patient-reported outcome (PRO)measures of health-related quality of life (EQ-5D-5L and the SF-12 v.2) in screening for anxiety and depressive symptoms in type 2 diabetes patients in primary care setting in Alberta. The researchers opted to explore these measures given their increasing use in the healthcare system in routine outcome measurement.

The researchers found that the EQ-5D-5L and the SF-12 to be suitable tools for screening for anxiety and depressive symptoms in adults with type 2 diabetes. The anxiety/depression dimension of the EQ-5D and the MCS score of the SF-12 had the best performance in screening for these symptoms.

Al Sayah stated “These tools present a unique opportunity for a standardized approach for routine mental health screening in primary care settings within the context of routine outcome measurement initiatives, particularly for patients with chronic diseases”. And added “Users should consider all pros and cons of each measure while selecting a PRO measure that would also serve as a screener for mental health”.
