Lumeris Introduces Tom™, an AI-Powered Breakthrough to Transform Primary Care
Industry's first Primary Care as a Service™ offering to tackle the 2-billion-hour primary care gap
AI-powered care team member to expand capacity, reduce burden, and improve patient access to care unveiled at ViVE 2025 in Nashville
ST. LOUIS, Feb. 19, 2025 /PRNewswire/ -- Lumeris, a leader in healthcare technology and services, today introduced Tom™, the industry's most advanced AI-powered Primary Care as a Service™ solution designed to support overburdened physicians and their teams while improving patient access to care. Tom is an AI-powered care team member embedded in clinical workflows, proactively extending the primary care team's reach across critical patient management areas including prevention and wellness, care coordination, social determinants of health, population health, and chronic disease management.
Primary care is essential for delivering quality outcomes, managing chronic diseases, and effectively containing healthcare costs. However, primary care is increasingly strained and inaccessible. Today, 100 million Americans do not have access to a primary care provider, with the imbalance between primary care demand and supply exceeding 2 billion hours annually and growing. This gap cannot be closed with human resources alone.
Meet Tom
Tom is designed to transform primary care by expanding capacity, reducing administrative burdens, and improving patient access. Built on over 20 years of researching and supporting the needs of physicians, patients, and health systems, and powered by more than five years of AI innovation, Tom uses meticulously curated data and carefully selected large language models to tackle key challenges in delivering personalized care and drive next-best actions at both the patient and population levels.
'The impact of Tom's technology is profound. We can extend primary care to 100 million Americans who don't have access. We can upgrade the quality of primary care for all patients, and lower costs by 50% or more,' said John Doerr, chairman of Kleiner Perkins. 'Tom's 'Primary Care as a Service' addresses the most pressing needs of our $5 trillion healthcare industry. Tom's insights and ability to communicate with patients and providers at any level are transformative. Patients and providers will welcome the innovation and outcomes.'
Unlike traditional analytics-based systems that merely inform care teams and increase their workloads, Tom acts. Operating 24/7 within primary care workflows, Tom autonomously executes next-best actions, including scheduling screenings and appointments, monitoring medication adherence, conducting post-discharge outreach, and sharing patient education – all while working within a shared care plan and escalating issues when necessary. This allows care teams to significantly expand their capacity to serve more patients with more comprehensive services.
Tom's powerful presence at the point of care, delivering real-time and data-driven insights, strengthens clinical decision-making and personalizes interventions. By integrating social determinants of health data, clinical guidelines and adaptative personalization, Tom increases patient engagement while reducing care team burdens and closing the primary care gap.
'We are addressing the 2-billion-hour primary care shortage head-on,' said Mike Long, chairman and CEO of Lumeris. 'The urgency and magnitude of the problems mean no one company can solve it alone. We are grateful for the strong support Tom is receiving from leading provider, academic, technology, and services organizations from across the country.'

How Kennedy's overhaul could make vaccines more expensive
Health and Human Services Secretary Robert F. Kennedy Jr.'s moves to upend decades of vaccine policy could hit patients hardest in their wallets, as shifting guidance over shots could make insurance coverage confusing and scattershot. For decades, the Centers for Disease Control and Prevention's (CDC) independent advisory panel recommended which shots Americans should get and when. The Affordable Care Act requires all insurance companies to cover, for free, all vaccines the panel recommends. Those recommendations also help states decide which shots should be mandated for schoolchildren. Kennedy's most recent move to purge the entire advisory panel and replace them with his own handpicked members, including several vocal vaccine critics, is throwing that process into doubt. 'If we have a system that has been dismantled — one that allowed for open, evidence-based decisionmaking and that supported transparent and clear dialogue about vaccines — and then we replace it with a process that's driven largely by one person's beliefs, that creates a system that cannot be trusted,' Helen Chu, a newly ousted member of the panel and professor of infectious disease at the University of Washington School of Medicine, said during a press conference. Vaccine prices vary, but without insurance, coronavirus vaccines can cost nearly $150, the MMR shot ranges from $95 to nearly $280, and the HPV vaccine can exceed $300, according to CDC data. Individual pharmacies could charge even more. Candace DeMatteis, policy director at the Partnership to Fight Infectious Disease, said she worries about creating a two-tiered system. 'Out of pocket costs for vaccines become an issue where we could end up with a system where some people can afford vaccinating themselves and their families and others cannot,' DeMatteis said. Prior to enactment of the Affordable Care Act, vaccine coverage varied significantly depending on the type of insurance a person had. If the CDC's Advisory Committee on Immunization Practices (ACIP) changes recommendations for existing vaccines or doesn't recommend new ones, maintaining access will be difficult. 'It's a seismic shift, if you will, away from facilitating access by removing coverage and cost barriers, to one where there's great uncertainty and coverage and cost issues become barriers,' DeMatteis said. It's not clear what the vetting process was for the eight people Kennedy appointed to the ACIP, or how prepared they will be for their first meeting, which is scheduled to occur in less than two weeks. According to a Federal Register notice, the panel is scheduled to vote on recommendations for COVID-19 vaccines as well as meningococcal, HPV, influenza, and RSV vaccines for adults and maternal and pediatric populations. Health experts said they have serious questions about what direction the new panel will take and whether Americans will still have access to free vaccines, including the coronavirus shot, in time for fall respiratory season. If the ACIP is no longer a reliable, independent authority on vaccines, it 'will be replaced by a patchwork of different policies by different states, and each state will have to make its own decisions,' Chu said. 'Washington state is a place where we have experts and scientists who work together. There are other states where this may not exist, or where they may not choose to recommend vaccines. So that is going to create a lot of chaos,' she added. Some state health officials have already begun taking steps in that direction. The Illinois Department of Health said on social media it will be convening its own vaccine advisory committee and national experts 'to ensure we continue to provide clear, science-backed vaccine guidance for our residents.' When Kennedy unilaterally changed the COVID-19 vaccine guidance earlier this month to remove recommendations for pregnant women and change the open recommendation for children, the Wisconsin Department of Health Services said it would continue to recommend the shots for every person at least 6 months old. 'The recent changes in CDC guidance were not made based on new data, evidence, or scientific or medical studies, nor was the guidance issued following normal processes,' the agency said in a statement. Tina Tan, president of the Infectious Diseases Society of America, said her organization as well as other major medical groups including the American Medical Association and the American Academy of Pediatrics Academy have been speaking with insurance companies to urge them to continue paying for shots, even if the panel changes recommendations. Tan mentioned an initiative launched in April by a group of public health experts called the Vaccine Integrity Project, which is working to create an alternative process to maintain vaccine access. The initiative is funded by a foundation backed by Walmart heiress Christy Walton and led by Michael Osterholm, director of the University of Minnesota's Center for Infectious Disease Research and Policy. Federal law is specific that insurance provisions are tied to the ACIP. Specialty organizations may have expertise to make their own recommendations, but they will still require the cooperation of insurance companies. States are also more limited, and they don't have the same power as the federal government to force coverage. 'I think it remains to be seen what the insurers are going to do,' Tan said. 'However, hopefully, with the discussions going on, they can get the insurers to understand that vaccines are extraordinarily safe and effective and are the best tool that we have to protect persons of all ages against serious vaccine preventable diseases.'

Americans Warned Not to Drink Coffee in 3 States
Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content. Americans are being advised to avoid drinking coffee, with forecasters warning of "dangerously hot conditions" across parts of Nevada, California, and Arizona. Why It Matters The National Weather Service (NWS) warns that heat related illnesses increase significantly during extreme heat events. What To Know It is generally recommended to avoid drinking coffee in hot weather due to its diuretic effect, which can lead to dehydration. Caffeine, found in coffee, can increase fluid loss through urination, making it harder for your body to stay hydrated, especially when you are already sweating more in the heat. Some parts of south central Arizona were expected to see temperatures up to 115 degrees Fahrenheit. The agency warned that overexposure to major heat can cause heat cramps and heat exhaustion to develop. Without intervention, it can lead to heat stroke, it added. Triple-digit temperatures were also expected in Lake Mead and its surrounding areas, with the service cautioning the these were dangerously hot conditions for early June. Death Valley National Park could see temperatures up to 120, according to the NWS. Signage warns of extreme heat danger at the salt flats of Badwater Basin inside Death Valley National Park on June 17, 2021, in Inyo County, California.

Fallon/AFP via Getty Images "Do not leave young children and pets in unattended vehicles," read the extreme heat warning, which also applied to a portion of northwest Arizona, southeast California, and southern Nevada. "Car interiors will reach lethal temperatures in a matter of minutes." A post from the NWS' Las Vegas office advised people in affected areas not to drink alcohol or caffeine, as they speed up dehydration. It also said heavy foods should be avoided, as meals high in protein can also speed up dehydration. The NWS noted that these warnings indicate dangerously hot weather, even by local norms. "Actions should be taken to lessen the impact of the extreme heat," it said. What People Are Saying AccuWeather meteorologist Chad Merrill told Newsweek that the Lake Mead area would see high temperatures between 107-112 degrees Sunday and Monday. "Tuesday's high will be 105-108 degrees. Wednesday will reach 107-115 degrees. Thursday and Friday will reach 105-112 degrees," Merrill said. "Temperatures will then drop several degrees next weekend with a more notable cooling trend Sunday, June 22-Tuesday, June 24." The National Weather Service forecast office, Las Vegas, said on X, formerly Twitter, Saturday: "Above-normal temps continue through the weekend & most of next week. Extreme Heat Warning in effect for Sunday (Father's Day). This heat coupled with very dry conditions will increase fire danger. Be extra cautious if recreating with sparks or flame." The NWS said on X, Wednesday: "During hot and humid weather, your body's ability to cool itself is challenged in ways you may not expect. When your body heats too rapidly, or when too much fluid or salt is lost through dehydration or sweating, you may experience a heat-related illness. Stay weather-ready by learning the symptoms of extreme heat exposure and the appropriate responses." What Happens Next At the time of writing, the latest extreme heat warnings were set to remain in effect until 8 p.m. on Monday.

Your morning shower is ruining your nighttime sleep, says expert — here's why
There's nothing like a refreshing shower in the morning to kickstart your day. However, if you're struggling to sleep this summer, that step in your morning routine may be to blame. Yes, while 60% of Americans like to shower in the morning, NHS physician Dr Tim Mercer at Opera Beds says it may be wise to switch to an evening shower to improve your sleep. And, no, it's not because a nice, warm shower before bed is relaxing. It actually all comes down to a particular reason regarding hygiene. So, if you're a morning showerer or prefer an evening rinse, read on to discover why your sleep hinges on your showering schedule. An evening shower is better for sleep for a particular reason: allergies. "Allergies can hit hard, especially at night," says Dr Mercer. 'For many, that means disrupted sleep, itchy eyes, and endless sneezing." Mercer explains that we collect allergens such as pollen or dust mites throughout the day, so you're likely taking all these allergens to bed with you by not showering in the evening. Get instant access to breaking news, the hottest reviews, great deals and helpful tips. "Pollen also clings to clothes, hair, and bedding, creating an invisible storm of irritation," the physician says. "You can shower before bed to wash off pollen, stopping it from transferring to your pillow." For more advice about allergies and sleep read our guide on how to sleep with allergies. If you're debating whether a hot vs cold shower is better for sleep, research and sleep experts tend to lean towards warm. A 2019 review of 13 studies found a warm bath or shower between 40 and 42.5 °C improved sleep quality and efficiency. "A warm shower taken one to two hours before bedtime triggers vasodilation (blood vessel expansion) in your extremities, which helps dissipate core body heat more efficiently afterward," Dr. David Rosen, medical director at sleep apnea treatment company Complete Sleep, recently told Tom's Guide. "This enhances your natural temperature drop." While a warm shower can prepare you for bed, showering too close to your bedtime may actually ruin your sleep. Like Dr Rosen mentioned above, try to shower around one to two hours before shuteye. Studies have shown that aromatherapy can improve sleep and relaxation, so try incorporating soothing scents into your evening shower. You can introduce relaxing scents through soaps or even shower mists, selecting products with calming fragrances such eucalyptus (which research shows can reduce congestion and sleep apnea) and lavender (studies show it increases quality of sleep and reduce anxiety).
