Climate-fueled wildfires take toll on tropical Pacific isles

WAIMEA, Hawaii (AP) — A metal roof sits atop the burned remains of a homestead on the once-lush slopes of Hawaii’s Mauna Kea — a dormant volcano and the state’s tallest peak — charred cars and motorcycles strewn about as wind-whipped sand and ash blast the scorched landscape.

Generations of Kumu Micah Kamohoalii’s family have lived on these lands reserved for Native Hawaiians, and his cousin owns this house destroyed by the state’s largest-ever wildfire.

“I’ve never seen a fire this big,” Kamohoalii said. “Waimea has had fires, many of them before and some maybe a few hundred acres, but not this size.”

The fire has burned more than 70 square miles (181 square kilometers) in the two weeks it has been going. But it wasn’t the first time this area has burned, and won’t be the last. Like many islands in the Pacific, Hawaii’s dry seasons are getting more extreme with climate change.

“Everyone knows Waimea to be the pasturelands and to be all the green rolling hills. And so when I was young, all of this was always green,” Kamohoalii said. “In the last 10 to 15 years, it has been really, really dry.”

Huge wildfires highlight the dangers of climate change-related heat and drought for many communities throughout the U.S. West and other hotspots around the world. But experts say relatively small fires on typically wet, tropical islands in the Pacific are also on the rise, creating a cycle of ecological damage that affects vital and limited resources for millions of residents.




From Micronesia to Hawaii, wildfires have been a growing problem for decades. With scarce funding to prevent and suppress these fires, island communities have struggled to address the problem.

“On tropical islands, fires have a unique set of impacts,” said Clay Trauernicht, an ecosystems and wildfire researcher at the University of Hawaii. “First and foremost, fires were very rare prior to human arrival on any Pacific island. The vegetation, the native ecosystems, really evolved in the absence of frequent fires. And so when you do get these fires, they tend to kind of wreak havoc.”

But it’s not just burnt land that is affected. Fires on islands harm environments from the top of mountains to below the ocean’s surface.

“Once a fire occurs, what you’re doing is removing vegetation,” Trauernicht said. “And we often get heavy rainfall events. All of that exposed soil gets carried downstream and we have these direct impacts of erosion, sedimentation on our marine ecosystems. So it really hammers our coral reefs as well.”

Pacific island reefs support local food production, create barriers to large storm surges and are a critical part of tourism that keeps many islands running.

The wet season on tropical islands also causes fire-adapted grasses to grow tall and thick, building fuel for the next summer’s wildfires.

“Guinea grass grows six inches a day in optimal conditions and a six-foot tall patch of grass can throw 20-foot flame lengths,” said Michael Walker, Hawaii’s state fire protection forester. “So what we have here are really fast-moving, very hot, very dangerous fires.”

Walker said such non-native grasses that have proliferated in Hawaii are adapted to fire, but native species and shrubs are not.

“While (these wildfires) may not compare to the size and duration of what folks have in the western United States, we burn a significant portion of our lands every year because of these grass fires, and they’re altering our natural ecosystems and converting forests to grass,” he said.

The latest wildfire on Hawaii’s Big Island burned about 1% of the state’s total land, and other islands in the Pacific such as Palau, Saipan and Guam burn even more — up to 10% in severe fire years.

On average, Guam has nearly 700 wildfires a year, Palau about 175 and Saipan about 20, according to data from 2018.

Guam, like many other places, has long used fire as a tool. Farmers sometimes use it to clear fields and hunters have been known to burn areas while poaching.

The U.S. territory’s forestry chief Christine Camacho Fejeran said fires on the island are mostly caused by arson. “So all of Guam’s wildfires are human-caused issues, whether it’s an intentional or an escaped backyard fire or another (cause),” she said.

On average, Fejeran said, 6,000 to 7,000 acres (2,430 to 2,830 hectares) of the island burns each year, amounting to about 5% of its land.

While no homes have been lost to recent wildfires on Guam, Fejeran believes that trend will come to an end — unless more is done to combat the fires.

The island has made some changes in fire legislation, management, education and enforcement. Arson has become a chargeable offense, but Fejeran says enforcement remains an obstacle in the tight-knit community.

Back in Hawaii, last week’s blaze destroyed three homes, but the fire threatened many more.



Mikiala Brand, who has lived for two decades on a 50-acre homestead, watched as flames came within a few hundred yards (meters) of her house.

As the fire grew closer, she saw firefighters, neighbors and the National Guard racing into her rural neighborhood to fight it. She had to evacuate her beloved home twice in less than 24 hours.

“Of course it was scary,” she said. “But I had faith that the strong, the brave and the talented, and along with nature and Akua, which is our name for the universal spirit, would take care.”

Demonstrating the tenacity of many Native Hawaiians in her farming and ranching community, Brand said, “I only worry about what I have control over.”

Down the mountain in Waikoloa Village, a community of about 7,000, Linda Hunt was also forced to evacuate. She works at a horse stable and scrambled to save the animals as flames whipped closer.

“We only have one and a half roads to get out — you have the main road and then you have the emergency access,” Hunt said of a narrow dirt road. “Everybody was trying to evacuate, there was a lot of confusion.”

The fire was eventually put out just short of the densely populated neighborhood, but had flames reached the homes, it could have been disastrous on the parched landscape.

“When you have high winds like we get here, it’s difficult no matter how big your fire break is, it’s going to blow right through,” Hunt said.


WILD GOAT SKULL AFTER FIRE 


While fires are becoming more difficult to fight because of dry and hot conditions associated with climate change, experts say the Pacific islands still can help prevent these blazes from causing ecological damage and property losses.

“Fire presents a pretty interesting component of kind of all these climate change impacts that we’re dealing with in the sense that they are manageable,” said Trauernicht, the University of Hawaii wildfire expert.

In addition to education and arson prevention, he said, land use — such as grazing practices and reforestation that reduce volatile grasses — could help.

“It’s within our control, potentially, to reduce the impacts that we’re seeing with fires,” Trauernicht said. “Both in terms of forest loss as well as the impacts on coral reefs.”

Black howler monkeys adapt mental maps like humans
















Peer-Reviewed Publication

THE COMPANY OF BIOLOGISTS

Ever since humans began committing their view of the world to flat slabs of rock and papyrus, we had a sense that our mental maps are laid out in much the same way. However, our mental maps are nothing like paper maps. Humans rely on route-based maps. These internal maps, also used by animals, are composed of well-trodden routes linking frequently visited locations, with little understanding of where these routes lie relative to one another. Yet, humans are able to supplement these rudimentary representations with knowledge of the distances we cover and direction to take occasional short-cuts. Yet many creatures negotiate far more complex environments and need to navigate efficiently, so being able to combine knowledge of separate routes to take short cuts would be useful. Can other animals navigate like humans? Black howler monkeys (Alouatta pigra) comb the forests of Mexico, Belize and Guatemala in search of fruit and edible vegetation, so Miguel de Guinea (Oxford Brookes University, UK), Sarie Van Belle (University of Texas at Austin, USA) and colleagues from Mexico and the UK wondered whether the primates are also capable of refining their route-based mental maps. The team publishes their discovery that black howler monkeys adapt their mental maps in the same was as humans, making them the first animal capable of navigating like us, in Journal of Experimental Biology at https://journals.biologists.com/jeb.

However, GPS-tagging the endangered primates wasn’t possible, so de Guinea and his colleagues had no choice but to visit the forests covering the Mayan ruins in Palenque National Park, Mexico, and follow the roaming animals. ‘We’d arrive at the study area where our focal group was expected to be found before sunrise’, says de Guinea, explaining that it was relatively easy to locate the troops of black howler monkeys, from 4 to 11 individuals, as they called loudly in the morning. Then de Guinea, Van Belle, field assistant Elsa Barrios and an international team of volunteers pursued the monkeys, at ground level, wherever they roved through their 50-hectare domain. ‘Sometimes the monkeys decided to travel to the top of the tallest temple in the area, making us climb at a very fast pace in intense heat to reach them’, says de Guinea. On other occasions, the primates dragged the scientists across steep waterfalls. One time the monkeys encountered a 5m gap on one of their regular routes; ‘a tree had fallen overnight’, Van Belle explains. ‘They stopped for half an hour and then travelled along the edge to reconnect with the second half of their travel path… as if they knew this was a new obstacle and they needed to consider their options on what to do next’, she laughs.

After a year of tracking five groups of black howler monkeys, de Guinea and Van Belle painstakingly reconstructed the monkeys’ movements as they covered 91.5km over 250 days, repeatedly revisiting their favourite fruit trees – always approaching from a few select directions – travelling through the same sequences of trees. In contrast, when the pair simulated how the animals would move if they were roving randomly through the park, the virtual primates rarely revisited the same routes. The black howlers were clearly following mental maps of familiar routes, like humans.

In addition, the researchers compared the distances covered by the foraging monkeys with the routes used by the simulated primates, and it was evident that the black howlers were able to link routes together in order to navigate between distant locations. They can supplement their simple route-based view of the world with knowledge of direction and the distances between locations to take short-cuts and manoeuvre efficiently through the ever-changing forest. ‘It was a big effort to collect such detailed and reliable data, but it was worth it to understand the fascinating cognitive skills that black howler monkeys demonstrate in the wild’, says de Guinea.

Solutions to help pollinators can be tested using a “virtual safe space” tool created by scientists at the University of Exeter in collaboration with farmers and land managers.

BEE-STEWARD is a decision-support tool which provides a computer simulation of bumblebee colony survival in a given landscape.

The tool lets researchers, farmers, policymakers and other interested parties test different land management techniques to find out which ones and where could be most beneficial for bees. 

BEE-STEWARD – which is freely available online – is a powerful tool that can make bumblebee survival predictions, according to a new study.

“We know that pollinator decline is a really big problem for crops and also for wildflowers,” said Dr Grace Twiston-Davies, of the Environment and Sustainability Institute at the University of Exeter’s Penryn Campus in Cornwall. 

“BEE-STEWARD takes into account the many complicated factors that interact to affect bumblebees.”

“This provides a virtual safe space to test out different bee-friendly management options."

“It’s a free, user-friendly tool and we have worked with land managers and wildlife groups on the ground to create it together.”

Disentangling the many factors that affect bumblebee colonies is incredibly complicated, meaning real-word testing of different methods by land managers is often not feasible.  

This problem prompted the Exeter scientists to create the BEEHAVE (honeybees) and Bumble-BEEHAVE (Bumblebees) computer models. But to help bumblebees thrive across our landscapes, these tools need to be used by people on the ground and not just scientists.

BEE-STEWARD has been designed with and for land managers, farmers and conservation practitioners to test out different ideas for land management and predict the impact that these may have on bumblebee survival.

BEE-STEWARD is being used by the Bumblebee Conservation Trust to help test and guide land management to help bumblebees and farm business thrive in Cornwall. Using BEE-STEWARD, bee-friendly actions are being tested across 1,500 ha of land in collaboration with the Duchy of Cornwall Estate, the National Trust, Treiwthen Dairy and Kellys of Cornwall.

BEE-STEWARD can simulate the growth, behaviour and survival of UK bumblebee species living in a landscape providing various nectar and pollen sources to forage on.

“The BEE-STEWARD model is a significant step towards enabling practitioners to support bumblebee populations,” said Professor Juliet Osborne, who leads the team.

 “The tool can be used to inform conservation and farming decisions and for assigning bespoke management recommendations.”

Professor Osborne and team won the BBSRC Social Innovator of the Year 2017 award for creating the BEEHAVE models.

"We have worked with researchers and landowners who have been using the model and have given us valuable feedback so we could improve our models further" said model developer Dr Matthias Becher.

“Testing the BEE-STEWARD tool has helped us predict how best to provide new and improved habitat for pollinators in an informed way, considering existing and proposed flora, flowering times and location.  This has focused decision making by identifying pollinator habitats that are lacking in a particular landscape, enabling us to focus our attention to improve and protect these specific areas” Ashley Taylor, Assistant Land Steward, Duchy of Cornwall Estate

BEE-STEWARD could be an important virtual test-bed for scientists exploring the impacts of different stressors on bumblebees and used by those with little or no modelling experience. Enabling a shared methodology between research, policy and practice for bumblebee survival.

“'The Bee-Steward model will be fantastic for conservation planning - it lets us time-travel to see the long-term results of changing management and compare all the possible options to see which one will work out best for bumblebees” Dr Richard Comont, Science Manager, Bumblebee Conservation Trust.

The BEE-STEWARD tool sits alongside a wider body of research by Prof. Osborne, Dr Twiston-Davies and Dr Becher around pollinator-friendly land-management. Their work on the NERC-funded SWEEP programme has included providing advice on Managing Green Space to improve biodiversity and wildlife habitats and working on the ‘Farming for the Nation’ trial for a new Agri-environment scheme with Cornwall Area of Outstanding Natural Beauty.

The new tool, published in Methods in Ecology and Evolution, is entitled: ‘BEE-STEWARD: a research and decision support software for effective land management to promote bumblebee populations’.

Cancer patients use less marijuana than general public


Study shows that between 2013-2018, as many states were legalizing recreational marijuana, cancer patients continued to abstain in large numbers

Despite Legalization, Marijuana Use Remains Low Among Cancer Patients

Richmond, Va. — Aug. 13, 2021 — Last month, three states – Virginia, South Dakota and Connecticut – joined the ranks of more than a dozen others that have legalized marijuana – also known as cannabis – for recreational use. Yet, despite these changing laws and growing social acceptance of the drug, a new study finds that use is still lower among cancer patients.

The study, published today in the journal Cancer by researchers at Virginia Commonwealth University Massey Cancer Center, analyzed data from nearly 20,000 people over a span of four years and found that reports of marijuana use peaked at 9% for cancer patients, compared to 14% among people with no cancer history.

“Even when we looked at whether someone used cannabis over the four years of observation and we control for things like age and race, cancer patients are still not increasing their use over time like the general population,” said study lead author Bernard Fuemmeler, Ph.D., M.P.H., associate director for population science and interim co-leader of the Cancer Prevention and Control research program at VCU Massey Cancer Center. “I would have expected them to have at least mirrored what was happening in the general population.” 

This paper drew on data collected between 2013 and 2018 from the Population Assessment of Tobacco and Health (PATH), which tracks a representative sample of Americans to survey smoking behaviors, including both tobacco and marijuana.

For people who never had cancer, rates of marijuana use rose during the four-year PATH study period. This same period saw a wave of recreational marijuana legalization sweep across the nation. 

“Because of law enforcement changing, we expect to see changes in attitudes and perceived benefits and harms,” said study co-author Sunny Jung Kim, Ph.D., Harrison Scholar at VCU Massey Cancer Center and assistant professor of health behavior and policy at the VCU School of Medicine. “This work gives us perspective on prevalence of cannabis use among cancer patients and how it has changed over time.”

But why aren’t cancer patients following the same trend as the rest of the population? The odds of a cancer patient using marijuana in the past year were essentially flat between 2013 and 2018.

“There is that element of a life-changing moment when you have cancer,” said Fuemmeler, who is also a professor of health behavior and policy in the VCU School of Medicine and holds the Gordon D. Ginder, M.D., Chair in Cancer Research at Massey. “You have to be mindful of your health and contemplate whether something like cannabis is helpful or hurtful.”

Regardless of cancer history, this latest analysis revealed that people who reported higher levels of pain were more likely to use marijuana, whereas lower rates of marijuana use were seen among women, older people and those with higher incomes, medical insurance or better mental health.

The authors note the need for greater research into the health effects of marijuana use for cancer patients and survivors so that doctors and patients can have more informed conversations about whether the potential benefits might outweigh the risks.

“As with all health decisions, it’s best to talk to your doctor before making any big changes,” said study co-author Egidio Del Fabbro, M.D., the Thomas Palliative Care Endowed Chair and director of palliative care at VCU Massey Cancer Center and professor of internal medicine at VCU. “Now that marijuana is becoming legal in more parts of the country, we’re expecting more questions, and although we may not have all the answers, we’re here to listen and provide our patients with the best available evidence.” 

Additional authors on the study include Elizabeth Do, Ph.D., and Albert Ksinan, Ph.D., both of the VCU Department of Health Behavior & Policy.

‘Likes’ and ‘shares’ teach people to express more outrage online


Peer-Reviewed Publication

YALE UNIVERSIT

Social media platforms like Twitter amplify expressions of moral outrage over time because users learn such language gets rewarded with an increased number of “likes” and “shares,” a new Yale University study shows.

And these rewards had the greatest influence on users connected with politically moderate networks.

“Social media’s incentives are changing the tone of our political conversations online,” said Yale’s William Brady, a postdoctoral researcher in the Yale Department of Psychology and first author of the study. He led the research with Molly Crockett, an associate professor of psychology at Yale.

The Yale team measured the expression of moral outrage on Twitter during real life controversial events and studied the behaviors of subjects in controlled experiments designed to test whether social media’s algorithms, which reward users for posting popular content, encourage outrage expressions.

“This is the first evidence that some people learn to express more outrage over time because they are rewarded by the basic design of social media,” Brady said.

The study was published Aug. 13 in the journal Science Advances.

Moral outrage can be a strong force for societal good, motivating punishment for moral transgressions, promoting social cooperation, and spurring social change. It also has a dark side, contributing to the harassment of minority groups, the spread of disinformation, and political polarization, researchers said.

Social media platforms like Facebook and Twitter argue that they merely provide a neutral platform for conversations that would otherwise happen elsewhere. But many have speculated that social media amplifies outrage. Hard evidence for this claim was missing, however, because measuring complex social expressions like moral outrage with precision poses a technical challenge, the researchers said.

To compile that evidence, Brady and Crockett assembled a team which built machine learning software capable of tracking moral outrage in Twitter posts. In observational studies of 12.7 million tweets from 7,331 Twitter users, they used the software to test whether users expressed more outrage over time, and if so, why.

The team found that the incentives of social media platforms like Twitter really do change how people post. Users who received more “likes” and “retweets” when they expressed outrage in a tweet were more likely to express outrage in later posts. To back up these findings, the researchers conducted controlled behavioral experiments to demonstrate that being rewarded for expressing outrage caused users to increase their expression of outrage over time.

The results also suggest a troubling link to current debates on social media’s role in political polarization. Brady and his colleagues found that members of politically extreme networks expressed more outrage than members of politically moderate networks. However, members of politically moderate networks were actually more influenced by social rewards.

“Our studies find that people with politically moderate friends and followers are more sensitive to social feedback that reinforces their outrage expressions,” Crockett said. “This suggests a mechanism for how moderate groups can become politically radicalized over time — the rewards of social media create positive feedback loops that exacerbate outrage.”

The study did not aim to say whether amplifying moral outrage is good or bad for society, Crockett stressed. But the findings do have implications for leaders who use the platforms and policy makers who are considering whether to regulate them.

“Amplification of moral outrage is a clear consequence of social media’s business model, which optimizes for user engagement,” Crockett said. “Given that moral outrage plays a crucial role in social and political change, we should be aware that tech companies, through the design of their platforms, have the ability to influence the success or failure of collective movements.”

She added, “Our data show that social media platforms do not merely reflect what is happening in society. Platforms create incentives that change how users react to political events over time.”

Spiral of jack fish wins 2021 BMC Ecology and Evolution image competition

Peer-Reviewed Publication

BMC (BIOMED CENTRAL)


From furry crustaceans to hunting wasps and escaping frogs, the 2021 BMC Ecology and Evolution Image Competition has produced an impressive collection of celebrated images that showcase the diversity of Earth’s animal and plant life. All images are open access and available for use under a Creative Commons Attribution 4.0 (CCBY) license. 

The overall winning image by Kristen Brown from the University of Pennsylvania, Philadelphia, USA depicts a school of jack fish in a spiral formation at Heron Island in the Great Barrier Reef, Australia.

Kristen Brown said: “This image represents both the beauty and bounty of our oceans as well as the spiralling crisis unfolding within the marine environment. Coral reefs with high coral cover and plentiful fish populations like this one at Heron Island on the Great Barrier Reef are sadly becoming rarer. Without a concentrated effort to reduce greenhouse gas emissions and improve water quality, coral reefs as we know them are at risk of disappearing within our lifetime.”




Section editor Josef Settele recommended the entry, saying: “Marine biodiversity sustains life and the health of our planet, but human activities are threatening the well-being of the world’s oceans. Kristen Brown’s striking image is a symbol for the need for concentrated efforts to manage biodiversity loss and set conservation priorities.”

In addition to the winning image, the judges also selected an overall runner up, as well as winners in six categories: Conservation Biology; Evolutionary Developmental Biology and Biodiversity; Behavioural Ecology; Human Evolution and Ecology; Ecological Developmental Biology; Population Ecology; and the Editor’s Pick. The winning images celebrate Earth’s biodiversity and its evolutionary origins, from how species learn and develop, to conflict, collaboration and parasitic relationships, both between and within species.

The Population Ecology category winner was captured by Roberto García-Roa from University of Valencia, Spain, who also submitted the winning images for the Behavioural Ecology and Human Evolution and Ecology categories. It shows soldier termites migrating along a length of abandoned rope in a Malaysian forest.

Roberto García-Roa said: “Thousands of soldier termites are able to migrate in a complex social environment where each individual has its own mission framed altogether in a global objective: the survivorship and reproduction of the colony. In this case, these termites used meters of an abandoned rope to move across the Malaysian forest. Once humans disappear, nature recovers its space and uses what is needed to survive.”

The Editor’s pick titled ‘Eerie Stalker’ by Dimitri Ouboter from the Institute for Neotropical Wildlife and Environmental Studies, Suriname captures a Giant Gladiator Frog seconds before escaping from an attempted snake attack. Giant Gladiator Frogs have been previously observed escaping from the jaws of snakes by emitting distress calls, jumping and inflating their lungs, making it harder for small snakes to hold on to them.

The BMC Ecology and Evolution Image Competition was created to give ecologists and evolutionary biologists the opportunity to use their creativity to highlight their work and celebrate the intersection between art and science. It follows on from the BMC Ecology competition, which ran for seven years until BMC Ecology merged with BMC Evolutionary Biology to form BMC Ecology and Evolution. The winning images are selected by the Editor of BMC Ecology and Evolution and senior members of the journal’s editorial board.

Editor Jennifer Harman said: “We had a wonderful experience judging the fantastic images submitted to this year’s competition. Our section editors used their expertise to ensure the winning images were picked as much for the scientific stories behind them as for the technical quality and beauty of the images themselves. As such, the competition very much reflects BMC’s ethos of innovation, curiosity and integrity. We thank all those who took part in this year’s competition; we hope that our readers enjoy viewing these images and discovering the stories behind them.”

CDC’s “honor system” mask guidance threatened vulnerable communities


Commentary argues that the agency’s policies may have increased risk of transmission of COVID-19 in the Black community.

Peer-Reviewed Publication

MASSACHUSETTS GENERAL HOSPITAL

BOSTON – The Centers for Disease Control and Prevention (CDC) may have increased the threat of COVID-19 infection in the Black community and among some other racial and ethnic minority groups when the agency updated its mask guidance last May, according to a new commentary in the Journal of General Internal Medicine by two colleagues at Massachusetts General Hospital (MGH). At the time, the CDC announced that fully vaccinated people could go without masks in most circumstances, a policy recommendation that was intended to help restore a sense of normalcy, yet ignored certain realities that left some groups vulnerable, the authors argue.

A critical problem with the CDC’s May mask guidance was that there is no way to tell whether a person is fully vaccinated against COVID-19, says Simar Bajaj, a research fellow at MGH. That meant that the CDC was relying on the honor system to ensure that unvaccinated people continued to wear masks. However, earlier research indicates that people often lie about personal health information to avoid being judged, notes Bajaj. “Without a way to verify vaccination status, everyone is going to unmask,” he says, dooming the CDC’s mask guidance to fail.   

Blacks in the United States were the group most likely to suffer the consequences of that failure, for a number of reasons, say Bajaj and his coauthor, Fatima Cody Stanford, MD, MPH, MPA, MBA, who is director of equity in MGH’s endocrinology division. For example, at around the time the CDC announced the mask guidance in mid May, just 28 percent of Black Americans had received at least one dose of the COVID-19 vaccine, compared to 42 percent of white Americans and 52 percent of Asians. “That’s a huge gap,” says Bajaj, who says it’s partly due to vaccine hesitancy that “is a product of everyday racism that Blacks face when navigating the health system.”

What’s more, Black Americans are far more likely than white Americans to be employed in essential jobs, meaning they can’t lower their risk for infection by working remotely. Black Americans have more medical comorbidities, which made those who became infected more likely to become seriously ill. Throughout the COVID-19 pandemic, Blacks have had disproportionately high rates of rates of infection with the virus, hospitalization and death, point out Bajaj and Stanford.

All of these factors made the CDC guidance a threat to the Black community. “When you issue this one-size-fits-all guidance, it should come as no surprise that it could deleteriously impact communities that have been hurt the most already,” says Bajaj. A more nuanced approach, he suggests, might have used “quantitative benchmarks” to determine when it’s safe for a community to unmask, says Bajaj. One approach might be to set goals for what proportion of a community must be fully vaccinated before unmasking is recommended in a state, possibly with higher thresholds in certain racial or ethnic communities, he suggests. Digital health passes that could verify vaccination status are another tool that the CDC could explore.

Their Journal of General Internal Medicine “Viewpoint” article had already been accepted for publication when, in late July, the CDC changed its mask guidance once again, citing new scientific data about the rapidly spreading Delta variant of the COVID-19 virus—in particular, the fact that vaccinated people can transmit the variant. The revised advice encouraged vaccinated people in counties where transmission of the virus is “substantial” or “high” to wear a mask while in indoor public places. To Bajaj, that’s a step in the right direction, since the new guidance is using its own quantitative benchmark—degree of transmission in a county—to determine whether masks are necessary for vaccinated people.

“But it’s too little, too late. Once you have swung the pendulum in the direction of abandoning all caution, it’s hard to walk it back,” says Bajaj, adding that public health authorities should focus on increasing vaccination rates overall, including in communities of color, and promoting greater health equity: the idea of removing barriers to good health for all. “If we continue the current state of affairs, it will be a tale of two pandemics—one in the highly vaccinated, majority-white, suburban areas, and another ripping through and devasting minority communities,” says Bajaj. “I think that’s an unacceptable proposition.”

Bajaj is also a scholar in the department of the History of Science at Harvard College. Stanford is a physician-scientist in the departments of Medicine and Pediatrics and is an Equity Director at MGH. She is also director of Diversity for the Nutrition Obesity Research Center at Harvard Medical School.

Competitive success: New research finds performance feedback at clinics increases flu vaccination rates

Peer-Reviewed Publication

INSTITUTE FOR OPERATIONS RESEARCH AND THE MANAGEMENT SCIENCES

INFORMS Journal Management Science Study Key Takeaways:

  • Clinics that receive performance rankings saw a 12% increase in flu shots and outperformed all others.

  • Clinics that receive performance rankings try to avoid falling into last place; clinics near last place outperform other similar clinics by 23 percentage points.

  • Even a 1% increase in U.S. adult flu vaccination rates can translate to almost $400 million in societal benefits.

 

CATONSVILLE, MD, August 12, 2021 – Every year the flu threatens the health of millions of people. Experts continue to recommend annual flu vaccination as the best line of defense, but despite these recommendations, flu vaccination rates haven’t broken 50% in more than a decade. New research in the INFORMS journal Management Science seeks to overcome this. The study finds that performance feedback at healthcare clinics can significantly increase vaccination rates. This has important public policy implications. Citing other research, the authors highlight that even just a 1% increase in U.S. adult flu vaccination rates could translate to some $400 million in societal benefits.

The study, “Focusing Provider Attention: An Empirical Examination of Incentives and Feedback in Flu Vaccinations,” was conducted by Bradley Staats and Robert Niewoehner III, both of the University of North Carolina at Chapel Hill, in partnership with VaxCare, a technology company that partners with clinics to coordinate vaccination logistics. The study looked at 145 clinics in nine different states and tested whether financial incentives or performance feedback might improve vaccination rates.

“We find clinics that got performance rankings grew their flu vaccinations more than all other clinics. Specifically, our experiment led to a 12% increase in flu shots for these clinics,” said Staats, a professor of operations and Sarah Graham Kenan Scholar, faculty director of the Center for the Business of Health and associate dean of MBA programs in the Kenan-Flagler Business School at UNC-Chapel Hill. “We also find that the clinics who received rankings don’t want to come in last – that is, they do whatever they can to avoid the bottom rankings. Because of this, in trying move up, the clinics near last-place end up outperforming their corresponding control clinics by 23 percentage points – a significant margin!”

This research stands to have a very large impact. If even just a portion of the increased vaccination rates go to at-risk groups, this could avert serious health consequences.

“Even further – if most of an increase in flu shots went to seniors, the CDC estimates that this could prevent thousands of hospitalizations,” said Niewoehner, a doctoral candidate in the Kenan-Flagler Business School at UNC-Chapel Hill.

“Our study shows that behavioral interventions like our experiment can improve performance outcomes, even when targeting seemingly immutable trends, like flu vaccination rates. Going forward, we believe our findings hold great promise for improving public health and company operations in general.”
