Abstract

Methods 85 patients undergoing joint replacement were randomised to receive or not receive an RUL at hospital discharge. A postal RUQ was then administered to participants at 3-months after surgery. A blinded researcher extracted primary care resource use data in relation to the patient’s joint replacement from GP records from hospital discharge until completion of the 3-month RUQ. Data from both sources were coded into use of resource and number of contacts and two binary variables indicating perfect recall were calculated. For each resource use category, descriptive statistics were calculated by data source and trial arm, and adjusted odds ratios were estimated.

Highlights

Can using a resource use log in an economic evaluation alongside a randomised controlled trial reduce the amount of recall bias?
To determine whether giving patients a resource use log (RUL) at hospital discharge reduces recall bias in a follow-up resource use questionnaire (RUQ)
A postal RUQ was administered to participants at 3-months after surgery
