Restrictions On Prisoner Research Hurt Studies Of Racial Disparities, Yale Docs Say

Federal rules against including prisoners in medical research have negatively impacted studies involving black men, who are disproportionately imprisoned, according to a new study by Yale School of Medicine researchers.

Individuals who are already in ongoing studies must be dropped if they are incarcerated – compromising the ability of researchers to examine racial disparities in health outcomes studies, the Yale team says in the May issue of the journal Health Affairs.

“A black man who begins a research study is less likely to follow up because he is statistically more likely to be jailed or imprisoned during the study than his white counterpart,” said the study’s first author, Dr. Emily Wang, assistant professor at Yale School of Medicine. The impact of incarceration on health outcome studies was far less among white men, white women, and black women.

The study found that during the past three decades, high rates of incarceration of black men may have accounted for up to 65 percent of the loss of follow-up among this group. Conditions such as cardiovascular disease and sickle cell disease are more common among black men than white men, and have complex factors that influence illness and death. This makes it important for analysts to have access to a large number of cases, so that they can draw statistically significant conclusions, the researchers said.

In 1978 the federal government restricted research on prison inmates in medical studies — the result of decades of unethical research in correctional institutions. The government regulations bar study subjects from participating once they are incarcerated unless the study investigators apply for special permission through their institutional review board (IRB). If studies do not specify otherwise, community-recruited participants who enroll in studies cannot be followed while they are incarcerated. In certain jurisdictions, they cannot be followed after their release.

Wang and her co-authors examined the protocols of 14 studies funded by the National Heart, Lung, and Blood Institute. They looked for studies that had received IRB protocols to follow prisoners, and also looked at how much loss to follow-up there was. They found that none of the studies received IRB approval for prisoner follow-up; the team then estimated how many individuals may have been incarcerated during the time period, based on national data.

Under current circumstances, Wang said, the results of longitudinal studies may fail to accurately represent the experience of black populations and may bias estimates of racial disparities by either excluding people in prison or discontinuing longitudinal follow-up at the time of incarceration.

“We are missing opportunities to study the outcomes of research on this population, so treatments can be tailored,” Wang said. “It is important that research subjects who are incarcerated be allowed to continue participating in observational research that poses minimal risk to the participants.”

  1. Now a new word “racial disparities.” Color has nothing to do with criminals. Yale cans study the people out of jail they don’t have to study prisoners no matter what color. YALE must be looking for more favor from New Haven’s black Mayor. There is always an excuse to give a group attention so some politician can push an agenda with the help of a business or institute.
