September 18-22, 2023 | Harvard School of Public Health, Boston, MA
Dr. Ware will present his annual lecture entitled “State of the Art of Methods for Health Outcomes Measurement and Evaluation – I” during the September 16-23 course at the Harvard School of Public Health, Boston, MA.
The lecture will cover the 40-year evolution of survey content and noteworthy conceptual and methodological milestones in the history of improving patient-reported outcome measures (PROMs). The latter include: applications of item response theory (IRT) and waves of development of very homogeneous item banks that require increasing the number of generic PRO scales; contrasting efforts to develop summary measures that each cover a wider range; new “super” short-form items that improve psychometric performance over legacy tools; and standardized IRT-based metrics common to new and legacy generic PROs. A new generation of more valid and responsive disease-specific PROs will be discussed. These new methods, which are standardized across diseases and norm-based, yield a summary score that fills the gap between disease-specific symptoms that are not QOL and generic QOL measures that are not disease-specific. A new kind of adaptive survey logic that automatically adapts to the presence of multiple conditions will be discussed as a more practical solution to integrating disease-specific and generic measures into a common “dashboard” of PROs.
