Study compares health information exchange data versus patient self-reports to measure cancer screening uptake

This knowledge can inform targeted population outreach efforts to improve screening

2023-10-10

(Press-News.org) INDIANAPOLIS – Knowing which populations are following cancer screening guidelines is important to public health officials and policy makers as well as researchers developing strategies to improve adherence. A recent study is one of the first to compare using health information exchange (HIE) data with patient self-reported data as a means of gathering this intelligence.

The researchers found that completeness of information differed by data source and screening test. HIE data provided more information than patient self-reports about laboratory screening tests such as the fecal occult blood test for colorectal cancer screening and the human papillomavirus (HPV) test for cervical cancer screening. Patient self-reports provided more additional information than HIE data about cancer screening procedures such as colonoscopy or mammograms.

The most robust measurement approach involves collecting both HIE and self-reported screening information to draw upon their different strengths according to David Haggstrom, M.D., MAS, of the Regenstrief Institute, Indiana University Melvin and Bren Simon Comprehensive Cancer Center and IU School of Medicine. He is senior and corresponding author of the study.

More complete population data over time detailing cancer screening across populations -- broken down by geographic area, racial or ethnic groups or age range -- can help researchers, public health officials and policy makers gain more nuanced understanding of how many people within each population are receiving recommended screenings, which screenings, and at what intervals. This information can then inform targeted outreach efforts to improve screening of as many eligible individuals as possible.

Unlike electronic health records (EHRs) which typically contain information from a single healthcare setting or system, HIE data comes from numerous sources. A report of an individual’s screening at a facility in a healthcare system different from where primary care is received may not make it into an EHR but could be included in the data available from an HIE.

“We need to help people keep track of whether they are receiving services that may benefit their health and be aware of when those services come due, and to make sure that people who are eligible are being offered them,” said Dr. Haggstrom. “In the case of cancer screening, our clinical goal is to increase the likelihood of detecting a cancer early at a time when it could be treated more successfully than if it were detected later without screening.

“Our study was uniquely possible due to the data infrastructure created by the Regenstrief Institute and managed by the Indiana Health Information Exchange to better support the health of residents of Indiana,” added Dr. Haggstrom. He notes that HIEs in other states are in various stages of development, comprehensiveness and completeness.

This work was aided by a National Cancer Institute supplement to an Indiana University Melvin and Bren Simon Comprehensive Cancer Center grant (P30 CA082709-17S6).

“Comparison of health information exchange data with self-report in measuring cancer screening” is published in BMC Medical Research Methodology.

Seamlessly multiplexing memory storage and recall

2023-10-10

Every day we store memories, some of which we are able to recall later. But while we do so, do we keep on storing? Yes! We cannot afford to stop memory formation while we are retrieving prior ones. Imagine, for instance, that you are navigating the city while recalling last night’s events to a friend tagging along. Your brain must memorize aspects of the route even while you are in the story, so that you can find your way back later or reach your next destination. We seem to perform this task without much conscious effort. Big deal, one could say, as we know that the brain has trillions of synaptic connections, so parallel processing ...

The ribosome–depression link

2023-10-10

A group of ribosomal protein genes connect animal models of depression to human patients with major depressive disorder. In order to research depression treatments, scientists use a mouse model, inducing a state with similarities to depression though exposure to variable, unpredictable, and uncontrolled stressors over days or weeks. But is this state molecularly akin to what humans with major depressive disorder experience? To find out, Xiaolu Zhang, Mahmoud Ali Eladawi, and colleagues examine transcriptomics data from postmortem human brain tissue and from several mouse models of stress, seeking to pinpoint conserved ...

Ionic crystal generates molecular ions upon positron irradiation, finds new study

2023-10-10

Positron, the antiparticle of electron, has the same mass and charge as that of an electron but with the sign flipped for the charge. It is an attractive particle for scientists because the use of positrons has led to important insights and developments in the fields of elementary particle physics, atomic physics, materials science, astrophysics, and medicine. For instance, positrons are known to be components of antimatter. They are also powerful in detecting lattice defects in solids and semiconductors and in structural analysis of the topmost surface of crystals. Positronic compounds, namely ...

Having obesity before and during early pregnancy appears to be a strong indicator of risk for developing future cardiovascular disease and was significantly linked with adverse outcomes during pregnancy such as high blood pressure, preeclampsia, and gestational diabetes, according to a study published in Circulation Research that was funded by the National Institutes of Health. Researchers have known obesity is a risk factor for cardiovascular disease and pregnancy complications related to blood pressure. However, they did not know which factors – obesity or the pregnancy complications – played larger roles in influencing a person’s ...

Are we running out of water? Water security threatened by droughts and heatwaves worldwide

2023-10-10

Increased demand for water due to global population growth, coupled with the increasing frequency of extreme weather events, endangers our water security. Nonetheless, little is known about the relationship of water use by sectors and the occurrence of drought-heatwave events, particularly at the large scale. To unveil this issue, a group of researchers from the Department of Physical Geography from Utrecht University evaluated the responses of sectoral water use during droughts, heatwaves and compound (combined) events at a global scale. The study published in Environmental Research Letters shows that stronger sectoral water use responses are found for heatwaves compared to ...

Researchers find pre-Columbian agave plants persisting in Arizona landscapes

2023-10-10

A new paper in the Annals of Botany, published by Oxford University Press, reveals that researchers have found unaltered agave plant species cultivated by several early cultures including the Hohokam people, a large Native American group in the Southwest that existed between 300 and 1500 CE. Agave plants have been of great economic and social importance in the Americas for at least 9,000 years. Before people cultivated corn, agave plants were one of their main carbohydrate sources. Archaeological research indicates the Hohokam increased agricultural potential by building terraces for agave dry farming. Agricultural features such as terraces and rock piles were especially characteristic ...
