One area of Dr. Whitehurst’s current research concerns the assessment of quality of life for individuals living with spinal cord injury, with a specific interest in the validation of preference-based outcome measures suitable for use in economic evaluation. The concepts of health state description and valuation, comparability of alternative outcomes measures, and the application of economic evaluation techniques alongside clinical intervention studies have been common themes throughout his career. Other research interests include the paradigmatic distinction between clinical and economic evaluation, the implications of adaptation for health state valuation, and the relationship between health-related quality of life and subjective wellbeing.
Dr. Whitehurst was the project lead for Spinal Cord Injury & Secondary Complications: A Mixed-Methods Evaluation of Preference-based Instruments (Rick Hansen Institute – Translation Research Program), with ICORD researcher Dr. Marcel Dvorak and Dr. Vanessa Noonan (Rick Hansen Institute) as the co-applicants. The major findings from this project are described in the section below.
He is a co-applicant with ICORD Researcher Dr. Andrei Krassioukov on the CIHR Team Grant: Improved Cardiovascular Outcomes for Chronic Spinal Cord Injury, which is currently ongoing. Dr. Whitehurst is also the Principal Investigator on an ICORD Seed Grant with Drs. John Kramer and Jacquelyn Cragg.
According to a systematic review of preference-based health-related quality of life questionnaires in spinal cord injury research done by Dr. Whitehurst and his colleagues, cost-effectiveness is an increasingly important consideration for decision makers in all areas of health care. However, there is a distinct lack of conceptual or empirical research regarding the appropriateness of alternative preference-based health-related quality of life measures for SCI populations.
‘Short Form’ health surveys – such as the SF-36 and SF-12 – are widely used in medical research. SCI is no exception, despite oft-cited concerns regarding measurement properties for populations with physical impairment. Dr. Whitehurst’s findings suggest that although standardized Short Form health surveys are common within SCI research, attempts to add, delete, or modify items have resulted in a number of variants, often with minimal supportive psychometric evidence.
A focus group study explored the views of individuals living with SCI towards six preference-based health-related quality of life instruments with the objective of identifying ‘preferred’ outcome measures (from the perspective of the participants). The 35-item AQoL-8D was considered to be comprehensive, with relevant content (i.e. wheelchair inclusive) and applicable items. Participants had mixed perceptions about the other questionnaires, albeit to varying degrees. Empirical, comparative analysis of the favoured instruments identified in this study is currently under way.
