Study Shows Importance of Ensuring Participant and Provider Follow-up After a Genetic Screening Result
New research from the Healthy Nevada Project® finds that a confirmed diagnosis does not always result in changes to patient care
Reno, Nev. (April 27, 2022) – Presenting individuals with potentially life-altering health information doesn’t mean the individuals – or their healthcare providers – will act on it. Follow-up education and conversations about actionable care plans with patients and their doctors are key next steps, according to new research from the Healthy Nevada Project.
The Healthy Nevada Project is a genetic screening and research project that launched in 2016 as a partnership between DRI and Renown Health. The project now has more than 50,000 participants, with genetic sequencing provided by Helix.
Between September 2018 and September 2020, the Healthy Nevada Project successfully notified 293 participants that they were genetically at risk for hereditary breast and ovarian cancer syndrome, Lynch syndrome, or familial hypercholesterolemia – three common genetic conditions known collectively as the Centers for Disease Control and Prevention (CDC) Tier 1 conditions. In a study published today in Frontiers in Genetics, Healthy Nevada Project scientists looked at the impact that notifying a patient of a positive finding for a CDC Tier 1 condition had on the care that the patient received in the months and years that followed.
According to their results, among the 293 Healthy Nevada Project participants who were notified of their genetic risk of a CDC Tier 1 condition, 71 percent of participants with electronic health records shared their findings with healthcare providers. However, only 30 percent of the electronic health records for these patients contained documentation of the genetic diagnosis, and only 10 percent of examined patients experienced a possible change in care after receiving the results of their genetic screening.
“The Healthy Nevada Project was implemented with a ‘hands-off’ approach where the participants receive their findings and decide with whom and when to share those findings. The findings were not automatically added to their electronic health records,” said Dr. Gai Elhanan, health data scientist at DRI and co-lead author of the study. “What we’re learning now is that to ensure that important genetic findings are integrated into the care journey it is important to make their inclusion into the electronic health records part of the study.”
This study builds on previous Healthy Nevada Project research published in Nature Medicine demonstrating the importance of screening for CDC Tier 1 conditions, which affect about one in 75 individuals and can be mitigated or even prevented from developing into disease when detected early. This study found that as many as 90 percent of the CDC Tier 1 cases are missed by clinical providers during normal clinical care screenings and examinations.
During the current study, the Healthy Nevada Project scientists found that 19 percent of studied participants had already developed one of the CDC Tier 1 conditions, and thus would have potentially benefited from earlier notification about their condition. The study team hopes that their findings will encourage individuals in Nevada to obtain genetic testing for these relatively common conditions. Even if individuals are older or have already suffered from diseases related to these conditions, testing could also prove beneficial to siblings, children, and grandchildren who may also be at risk and who could subsequently be screened in the event of a positive finding.
The study team also encourages informing health care providers of the importance of incorporating genetic diagnoses into the pharmaceutical (for example, for Familial Hypercholesterolemia) and treatment advice given to patients.
“As a result of this analysis, the clinicians at Renown Health and the Healthy Nevada Project researchers have made significant changes, including obtaining informed consent from participants to report positive findings from their genetics reports directly into their electronic medical record,” said Daniel Kiser, M.S., assistant research scientist of data science at DRI and co-lead author of the study. “This will help both participants, their clinical providers, and the whole state maximize the long-term benefits of the Healthy Nevada Project voluntary population-based genetic screening.”

A new DRI-led study finds a 17.7 percent rise in COVID-19 cases after a prolonged 2020 wildfire smoke event in Reno, Nev.
Wildfire smoke may greatly increase susceptibility to SARS-CoV-2, the virus that causes COVID-19, according to new research from the Center for Genomic Medicine at the Desert Research Institute (DRI), Washoe County Health District (WCHD), and Renown Health (Renown) in Reno, Nev.
In a study published earlier this week in the Journal of Exposure Science and Environmental Epidemiology, the DRI-led research team set out to examine whether smoke from 2020 wildfires in the Western U.S. was associated with an increase in SARS-CoV-2 infections in Reno.
To explore this, the study team used models to analyze the relationship between fine particulate matter (PM 2.5) from wildfire smoke and SARS-CoV-2 test positivity rate data from Renown Health, a large, integrated healthcare network serving Nevada, Lake Tahoe, and northeast California. According to their results, PM 2.5 from wildfire smoke was responsible for a 17.7 percent increase in the number of COVID-19 cases that occurred during a period of prolonged smoke that took place between Aug. 16 and Oct. 10, 2020.
“Our results showed a substantial increase in the COVID-19 positivity rate in Reno during a time when we were affected by heavy wildfire smoke from California wildfires,” said Daniel Kiser, M.S., co-lead author of the study and assistant research scientist of data science at DRI. “This is important to be aware of as we are already confronting heavy wildfire smoke from the Beckwourth Complex fire and with COVID-19 cases again rising in Nevada and other parts of the Western U.S.”
Wildfire smoke may greatly increase susceptibility to SARS-CoV-2, the virus that causes COVID-19, according to new research from the Center for Genomic Medicine at the Desert Research Institute, Washoe County Health District, and Renown Health in Reno, Nev.
The full text of the study, “SARS-CoV-2 test positivity rate in Reno, Nevada: association with PM2.5 during the 2020 wildfire smoke events in the western United States,” is available from the Journal of Exposure Science and Environmental Epidemiology: https://www.nature.com/articles/s41370-021-00366-w
Reno, located in Washoe County (population 450,000) of northern Nevada, was exposed to higher concentrations of PM2.5 for longer periods of time in 2020 than other nearby metropolitan areas, including San Francisco. Reno experienced 43 days of elevated PM2.5 during the study period, as opposed to 26 days in the San Francisco Bay Area.
“We had a unique situation here in Reno last year where we were exposed to wildfire smoke more often than many other areas, including the Bay Area,” said Gai Elhanan, M.D., co-lead author of the study and associate research scientist of computer science at DRI. “We are located in an intermountain valley that restricts the dispersion of pollutants and possibly increases the magnitude of exposure, which makes it even more important for us to understand smoke impacts on human health.”
Kiser’s and Elhanan’s new research builds upon past work of studies in San Francisco and Orange County by controlling for additional variables such as the general prevalence of the virus, air temperature, and the number of tests administered, in a location that was heavily impacted by wildfire smoke.
“We believe that our study greatly strengthens the evidence that wildfire smoke can enhance the spread of SARS-CoV-2,” said Elhanan. “We would love public health officials across the U.S. to be a lot more aware of this because there are things we can do in terms of public preparedness in the community to allow people to escape smoke during wildfire events.”

Reno, Nev. (Sept. 22, 2020) – For people who suffer from asthma, wildfire smoke is more hazardous than other types of air pollution, according to a new study from the Desert Research Institute (DRI), the Renown Institute for Health Innovation (Renown IHI) and the Washoe County Health District (WCHD).
The study, which published last month in the journal Environmental Health, examined associations between airborne particulate matter (PM) from sources such as wildfire, transportation and industry, and medical visits for asthma at Renown Health’s emergency departments and urgent care centers in Reno, Nev. during the six-year period from 2013-2018.
According to their results, on days when wildfire smoke was present, elevated levels of PM2.5 (fine particles of 0-2.5 micrometers in size, about 30 times smaller than a human hair) led to a 6.1 percent increase in medical visits for asthma patients when compared with days of similar pollution levels that came from non-wildfire sources.
“Since we found significantly stronger associations of PM2.5 with asthma visits when wildfire smoke was present, our results suggest that wildfire PM is more hazardous than non-wildfire PM for patients with asthma,” said lead author Daniel Kiser, M.S., Data Scientist with DRI and Renown IHI.
Above, a timelapse video from DRI’s Western Regional Climate Center shows an impressive smoke front move into the city of Reno on August 18, 2013. The smoke, which rolls in at approximately 1:05 in the video, was from the American River fire near Sacramento, Calif.
An increase in the harmfulness of PM from wildfires compared to PM from other sources may be attributable to differences in the chemical composition of PM or changes in human behavior, since people are more likely to be outdoors in the summer, when wildfires typically occur. The research team notes that caution should be used when applying these results to other areas of the country, such as the Southeastern United States, since the harmfulness of wildfire smoke may be affected by the type of fuel that is being burned. Other factors, such as the distance that wildfire smoke was carried by the wind and burn temperature, may also play a role in the harmfulness of wildfire smoke.
The researchers found that air quality in the Reno area was affected by wildfire smoke on a total of 188 days during the study period. A total of 18,836 asthma-related emergency room and urgent care visits occurred over the same five-year period of time, indicating that the influences of wildfire smoke and other types of air pollution on this medical condition are important to understand.
“In places like Reno, where wildfire events occur regularly during parts of the year and are expected to become more frequent in the future, an accurate understanding of the impacts of wildfire smoke on population health is critical,” Kiser said.
