When India's Central Bureau of Investigation (CBI) arrested Ketan Desai, the president of the Medical Council of India (MCI) and president-elect of the World Medical Association, for allegedly accepting a bribe of 20 million Indian rupees from the vice-president of a medical college and hospital in the Punjab state, few in the country's medical community were surprised.

Many international statements have urged researchers, policy-makers and health care providers to collaborate in efforts to bridge the gaps between research, policy and practice in low- and middle-income countries. We surveyed researchers in 10 countries about their involvement in such efforts.

Gaps continue to exist between research-based evidence and clinical practice. We surveyed health care pro viders in 10 low- and middle-income countries about their use of research-based evidence and examined factors that may facilitate or impede such use.

They are billed as "healthcare professionals who spend years building expertise in their fields". Using materials grounded in science, they educate their peers in the risks and benefits of drugs. This is how Pfizer, the pharmaceuticals giant, describes the experts it hires to lead forums in which doctors are lectured on the use of its products. Yet New Scientist has found that some of Pfizer's experts have been disciplined for deficiencies in patient care, while others have been reprimanded for how they conducted drug research trials.
