A focus group study to understand biases and confounders in a cluster randomized controlled trial on low back pain in primary care in Norway.

ABSTRACT:

Background

Cluster randomized controlled trials are often used in research in primary care but creates challenges regarding biases and confounders. We recently presented a study on low back pain from primary care in Norway with equal effects in the intervention and the control group. In order to understand the specific mechanisms that may produce biases in a cluster randomized trial we conducted a focus group study among the participating health care providers. The aim of this study was to understand how the participating providers themselves influenced on the study and thereby possibly on the results of the cluster randomized controlled trial.

Methods

The providers were invited to share their experiences from their participation in the COPE study, from recruitment of patien
