Nearly two months after Hurricane Maria swept through Puerto Rico, the infrastructural damage remains evident — today, FEMA estimates that only 41 percent of the island has had power restored. But the impact on human behavior is just beginning to be understood.
Research collaborators from the Boston Children’s Hospital Computational Epidemiology Group, MIT Media Lab and Google, Inc., have shed light on the particulars of when people chose to move out of the hurricane’s path and how much travel has been hindered since destructive winds and flooding knocked Puerto Rico off the grid. …
How can the growing number of digital health startups sell their products to large-scale healthcare enterprises? Earlier this year, Rock Health, a San Francisco-based venture fund dedicated to digital health, conducted 30-minute interviews with executives at multiple startups and a few large healthcare organizations. They identified several key sticking points: navigating the internal complexities of hospitals, finding the right buyer, identifying the product’s value proposition and relevance to the hospital and avoiding “death by pilot.”
“The fact that we were able to predict influenza outbreaks faster than China’s national surveillance programs really shows the capacity for everyday, wearable digital health devices to track the spread of disease at the population level,” says the study’s lead author Yulin Hswen, who is a research fellow in Boston Children’s Computational Epidemiology Group and a doctoral candidate at the Harvard T. H. Chan School of Public Health.
China has 620 million mobile internet users who can theoretically access the standalone Thermia application from any computer, smartphone or even the Amazon Alexa assistant.
Although the Boston Children’s team has previously demonstrated that social media can be used to track disease, this is the first time they’ve shown that outbreaks can be predicted through an integrated wearable device and online tool. …
As the Zika epidemic continues to unfold, most affected countries are flying blind: they have limited government disease surveillance systems in place to track new cases. That leaves public health officials unable to estimate how fast Zika is spreading, where the hotspots are and when the outbreak will peak — much less contain it and prepare for cases of microcephaly and Guillain-Barré syndrome, both now presumed to be caused by the Zika virus.
“One of the things we really struggled with in the early days of Zika was a lack of official data sources,” says research fellow Maia Majumder, MPH, of the Computational Epidemiology Group at Boston Children’s Hospital. “Surveillance has been really lagging. When we don’t know how many cases there are day to day, week to week, it’s really hard to characterize how bad an outbreak is.”
A study this week led by Majumder suggests a readily available data source for estimating actual case counts on the ground: online local news reports, adjusted using data from Google search trends. …
Judges include representatives from the four founding hospitals — Boston Children’s Hospital, Cincinnati Children’s Hospital, Texas Children’s Hospital and Children’s Hospital of Philadelphia — and from Sesame Workshop, whose recently announced Sesame Ventures plans to support companies that “help kids grow smarter, stronger and kinder.”
John Brownstein, PhD, chief innovation officer at Boston Children’s and one of the judges on the panel, agrees with that mission. “When it comes to innovation, pediatrics is often a second thought or gets left out altogether,” he says. “I’m extremely impressed with the landscape this year and the breadth of startup ideas.” …
During the last decade or so, health care has been rapidly transforming from a reactive, paper-based system to a responsive digital model.
Massachusetts, under Gov. Charlie Baker’s leadership, has launched a comprehensive public-private partnership to accelerate the state’s digital health care sector. The partnership has identified multiple ways to drive investment and growth in the state.
Technology transfer from universities to private companies is just one example. In the past, each transfer required completely new agreements. Three new standardized templates for licensing, technology transfer and sponsored research will help facilitate these processes. In 2016, the partnership will expand its Mentorship Speakers Series with a stronger focus on digital health care. Finally, the Digital Healthcare Innovation Hub and Accelerator will provide a space to support and grow new digital health companies in Boston.
Vector visited with John Brownstein, PhD, Boston Children’s Hospital’s Chief Innovation Officer, to better understand the background and potential impact of this new initiative. …
At the moment, it would appear the bacteria are winning. Antibiotic resistance is on the rise globally (in part because much of the public may not really understand how antibiotics work), threatening doctors’ ability to treat bacterial infections and potentially making surgery, chemotherapy and other medical procedures whose safety depends on antibiotic prophylaxis more risky.
Mapping antibiotic resistance — which bacteria are resistant to which drugs, and where — can help clinicians and public health officials decide how best to focus their control efforts. The challenge to date has been compiling resistance data in geographically useful ways.
“The data about antibiotic resistance are fragmented across laboratories and hospitals globally,” says Derek MacFadden, MD, a doctoral student at the Harvard T.H. Chan School of Public Health who is working with the HealthMap team in Boston Children’s Computational Health Informatics Program. “Most of the data that are available are very high level, so you can’t get an understanding of regional-level antibiotic resistance.”
This is where ResistanceOpen could come in handy. This new tool, launched by HealthMap team this week during the World Health Organization’s World Antibiotic Awareness Week, provides a window into regional and local antibiotic resistance patterns across the globe.
“The main problems with measuring patient experience by survey are the small numbers of people who respond to surveys and the lag time,” says Jared Hawkins, MMSc, PhD, of Boston Children’s Hospital’s Computational Health Informatics Program (CHIP). “It can take up to two years before survey data are released to the public. Given that social media data are close to real time, we wanted to see if we could capture this discussion and if the content is useful.”
Hawkins, with Boston Children’s chief innovation officer, John Brownstein, PhD, and their colleagues collected more than 400,000 public tweets directed at the Twitter handles of nearly 2,400 U.S. hospitals between 2012 and 2013. Using machine learning, natural language processing and manual curation, they tagged 34,735 patient experience tweets directed at 1,726 hospital-owned Twitter accounts. …
