Development of a Multi-attribute Health Index: to Measure the Quality of Labour Analgesia: The QLA Index
The findings of this research will be used to develop a scale for measuring the quality of epidural pain relief achieved during labour and vaginal delivery.
|Study Design:||Observational Model: Cohort
Time Perspective: Prospective
|Official Title:||Development of a Multi-attribute Health Index to Measure the Quality of Labour Analgesia: Psychometric Development of a Quality of Neuraxial Labour Analgesia Scale|
- Psychometric instrument development study [ Time Frame: 5-6 years ] [ Designated as safety issue: No ]Exploration and description of language, nature, and variability of women's pain experiences during labour and delivery.
|Study Start Date:||July 2010|
|Estimated Primary Completion Date:||September 2015 (Final data collection date for primary outcome measure)|
The current lack of a tool to measure the overall quality of neuraxial pain relief provided in labour analgesia trials has produced studies unable to provide clear direction to clinical care and research. Our previous work explored and described the underlying dimensions and attributes of quality neuraxial analgesia from the perspectives of labouring women as the initial phase of development of an Index to measure this as an outcome in research. We now seek to confirm our findings as well as to generate additional items (descriptors) of quality neuraxial analgesia from the perspectives of parturients and experts (obstetrical anesthesiologists and experienced labour nurses). Once generated, the full list of items will be used to in a subsequent study involving only parturients (Item Reduction phase) to develop a scale permitting global measurement of quality neuraxial labour analgesia. The resulting scale, once validated, will provide researchers with a simple global measure for quality in labour analgesia research. This scale will be used later in our program of research to assist with validation studies of the larger Multi-attribute Health Index we are developing.
