How Privacy Policies Affect Genetic Testing

Study: State-level disclosure laws affect patients’ eagerness to have their DNA tested.


According to a new study by the MIT scientists suggests that different types of privacy laws in U.S. more likely to produce markedly different effects on the willingness of patients to have genetic testing done. Policies that focus on the privacy risks of genetic testing, and ask for patient consent to those risks, lead to a reduction in tests performed.

In any case, arrangements that accentuate cutoff points to encourage revelation of hereditary information without assent, and expressly characterize hereditary information as the property of the patient, prompt an expansion in the quantity of tests performed.

Catherine Tucker, a professor at the MIT Sloan School of Management said, “The one thing we found that had a positive effect [on the number of tests] was an approach where you gave patients the potential to actually control their own data.”

“By contrast, an approach which just emphasized consent, but with no parallel set of controls, actually the damaged the ability of hospitals to be able to persuade patients to adopt these tests.”

Genetic testing can give pointers of a person’s summed up the danger of gaining sicknesses and diseases. Those markers can goad individuals to seek after further indicative tests and medications and can decrease the frequency of infection itself. Genetic testing has likewise turned out to be more cost-productive in the course of the most recent decade, making it a much-touted strategy for customizing pharmaceutical.

Almost 1% of the population has gone through genetic testing in a hospital setting, which is what the study measured. Nonetheless, with that as a pattern, the investigation demonstrates how the distinctive sorts of hereditary security laws deliver changing testing results.

Contrasted with a gauge in which individuals, by and large, have had testing done 0.54 percent of the time, approaches underscoring tolerant control of hereditary information raise rate of testing by 83 percent. Be that as it may, arrangements generally advising patients of protection dangers, and requesting that they agree to those dangers without additionally control over their data, brought down testing by 69 percent. The examination depends on government overview information.

For the study, scientists collected data from the National Health Interview Surveys, part of the Centers for Disease Control and Prevention (CDC). Those surveys include questions about genetic testing that relate to cancer risks; the study used three waves of CDC data that comprise a sample size of 81,543 respondents.

The scientists really distinguished three fundamental sorts of state-level hereditary protection strategies. Notwithstanding the two sorts of approaches discernibly affecting testing level — those stressing basic patient agree to security dangers, and those guaranteeing more prominent patient control. Another kind of hereditary protection strategy expressly ensures that the patient’s hereditary information won’t be utilized by safety net providers, managers, or different suppliers of long-haul care or protection.

Tucker said, “An approach where you gave various guarantees about how the data would be used … actually had no effect.”

The outcomes strengthen the possibility that the correspondence of protection dangers is itself a critical piece of security strategy. All things considered, under both of the two sorts of approaches that create restricting impacts on testing levels, it is, in any event, conceivable that individual patients could see their information shared to an equivalent degree.

Scientists were motivated to conduct the research because personal genetics is “an area where privacy really, really matters when you think about how sensitive potentially your genomic data is.”

States have embraced protection laws accurately to guarantee that obvious hereditary dangers are not the reason for segregation in work, protection, and different aspects of municipal life.

Tucker said, “Our evidence is applicable to what happens in research hospitals on the forefront of medicine, and the kind of patients they attract. We look at a setting which is really quite formalized, a decision to get a personalized test in a hospital. There’s a whole other frontier out there of private testing companies.”

It is possible the less formal setting of home-based genetic testing might make people less wary of disclosing information. Alternately, people in hospitals might feel a heightened need for more medical information and thus be more likely to consent to test.
