Quantifying the Efficiency of Health Care Interventions: A Review of Time and Motion Studies presented at ISPOR Conferences between 2008 and 2013

Quantifying the Efficiency of Health Care Interventions: A Review of Time and Motion Studies presented at ISPOR Conferences between 2008 and 2013

Efficiency, in addition to effectiveness, is a major value driver for many health care interventions. Time and Motion (T&M) studies are observational studies aiming to quantify time for a process by disaggregating it into its constituting parts to measure task durations. This flexible methodology is employed to collect real-world efficiency outcomes and generate economic value messages to support launch and commercialization of novel biopharmaceutical products, medical supplies, and devices.

UBC conducted a review of the T&M studies presented at ISPOR meetings in the last five years. The main characteristics of each study were reviewed and discussed:

  • Type of medical intervention
  • Study design
  • Source of data
  • Number of groups examined
  • Type of time measurements performed
  • Statistical analyses, including testing for differences among groups or handling potential data centre clustering effect
  • Transformation of time into costs
  • Type of cost analyses performed

Measuring time endpoints prospectively is subject to variability and bias, and therefore caution should be taken during the design and implementation of these studies, as well as during the selection of the analytical processes to be used.
