Genomic Data for Oncology Research Available in Literature

Friday, May 30, 2014

Kathleen Foley imageData. Most of us in research are data-hungry and data-greedy. When we can’t get our hands on a certain piece of data our eyes start roaming, looking for the nearest match, like a teenage boy ravaging the fridge for the tenth time in a day. We will grab anything that resembles data, although we typically crave the hardcore, quantifiable, number-crunching data we’re used to, especially in cancer research. It’s funny, though, how in our hunger-driven craze, we can be blind to obvious sources of data.

Today, oncology researchers are all scrambling for genomic data. It’s the single most common data question I get from researchers. But genomic data are not yet available in most secondary data sources, such as administrative claims data or HIPAA-compliant electronic medical records. How then can we begin to explore the role of genomic information in cancer research? As Talia Foster points out in her opinion brief, Oncology Literature Reviews Reach a Tipping Point in Genomic Assessment, the literature is a readily available source that is prime for exploration.

The literature is a versatile source of information on genomic markers in cancer. It can be analyzed both qualitatively, as well as quantitatively, and as Ms. Foster points out, it can address a variety of questions. Rather than wait for our typical sources of cancer data to fully incorporate genomic data, we can access the genomic literature today. By leveraging this powerful and rich source of data, we can not only begin to address many of the questions about the role of genomic assessment in diagnosis, prognosis and treatment response, the prevalence of various mutations and real world use of targeted agents, but we can also begin to plan new research studies that will help us in our search to get the right treatments, to the right patients, at the right time. Are you looking for genomic data? Perhaps the time is right for you to think about the literature for your next data venture.

Impact of FDA Safety Warning on Dispensed Zolpidem Dose for Women

Friday, May 30, 2014
Debra Irwin imageThe television show recently aired a segment about gender differences in rates of drug metabolism. The program discussed a recent , one of the most popular insomnia medications on the market. The safety warning was based on new data that showed women metabolize Zolpidem more slowly than men. Hence, women would require a lower dose of Zolpidem in order to avoid next morning impairment. After viewing this episode, my colleague and I became interested in the impact that the FDA safety warning had on Zolpidem dispensing patterns.

We examined the dose dispensed to new Zolpidem users before and after the FDA safety warning was issued. Women who were new users of Zolpidem were significantly more likely to receive low-dose Zolpidem after the safety warning compared to women who were new users of Zolpidem in the time period before the safety warning. However, the overall proportion of women receiving low-dose Zolpidem after the safety warning remained quite low.

Our findings may have significant public health implications for women using Zolpidem. An alarmingly high proportion of women who were new Zolpidem users were dispensed high-dose Zolpidem, despite the FDA safety warning. These findings highlight the importance of the extensive communication efforts required to effectively disseminate information concerning drug label changes to healthcare providers and patients.

Oncology Treatments and Care Benefit from Big Data

Monday, April 7, 2014
discusses the latest use of IBM’s Watson computer for tackling the synthesis of complex information required to personalize cancer treatments to individual patients.   Drawing upon the medical literature, drug databases and patient genomic data, Watson will identify possible treatments for specific patients – tailored to their own genetic mutations. The application of Watson’s brain power to cull through an enormous amount of information is truly a step forward in the world of fighting cancer. The human brain can only synthesize small amounts of data at any given time, so having a computer help with the sifting and sorting is of tremendous value.

And so far, the reaction appears appropriately modest. Watson may be able to detect and identify, but Watson can’t interpret and place treatments into context the way doctors can. Watson is an aide that will hopefully free up human time for the things that human’s do best, such as interpret, understand, recommend, listen to and take into account patient emotions and family needs.

At Truven Health, our approach to big data is much the same. We use technology to simplify, organize and identify patterns of care, drivers of cost, or patient sub-groups. We draw upon many components of big data, from medical claims to hospital discharges, work productivity and oncology EMRs as well as the literature, to identify patient-level value in cancer treatments. And like our medical counterparts, we leave the heavy thinking, the place where intuition drives solutions and identifies new paths forward, to our researchers. Good technology in the hands of humans striving to treat and cure cancer is good for everyone!
