The revelation that data obtained for the US-based National Surgical A
djuvant Breast and Bowel Project (NSABP) from subjects enrolled at Hos
pital Saint-Luc in Montreal was falsified has eroded public trust in r
esearch. Institutions can educate researchers and help prevent unethic
al research practices by establishing procedures to monitor research i
nvolving human subjects. Research monitoring encompasses four categori
es of activity: annual reviews of continuing research, monitoring of i
nformed consent, monitoring of adherence to approved protocols and mon
itoring of the integrity of data. The authors describe characteristics
of research projects that may call for monitoring procedures in each
category. The form taken by such monitoring depends on the nature of t
he protocol. Although appropriate research monitoring requires substan
tial investment of personnel and financial resources, it is required u
nder guidelines regulating research involving human subjects in Canada
. Research monitoring is a step forward in re-establishing public conf
idence in medical research.
