There are persisting issues of real and perceived conflicts of interest. Some people will not be able to easily identify whether they have conflicts, or will have interests they are not aware of (e.g. they may not know where their university gets its funding sources). People funded by government may also be influenced by the government's current policy imperatives. These issues, including definitions of ‘independence’, are often complex.
There is a need to ensure that guideline development groups include wide representation from different health disciplines and people with different backgrounds and skills, and it should be clear where there are contrasts between sets of norms, values and ideals. This will allow members of guideline development groups and committees to get a wider picture of each contributor’s influences.
The issue of conflict of interest is not a solely medical/health issue. For example, it is important that all influences and interests are known when members of a jury are selected. Directors and businesses also have formalised processes for declaring and managing conflicts. People submitting journal articles are also required to make declarations in accordance with the statements on conflicts of interest in medical journals by the World Association of Medical Editors and the International Committee of Medical Journal Editors. Medical journals need to be checked to ensure they follow their own code of ethics and actively enforce their policies with contributors.
There is a need to educate clinicians and consumers in critical appraisal of intervention studies and other types of studies, in part to enable awareness of the pervasive risk of bias from diverse sources.
