Good morning. On the agenda today: health care workers on climate change, an alternative to a cancer-causing sterilizer, and what a rehabilitation researcher learned from his daughter's traumatic brain injury.

Clinicians want health care to do better on climate

Health care workers on the front lines — nurses, physicians assistants, nurse practitioners, primary care physicians, and specialists — want their institutions to move the needle on climate change, a new Commonwealth Fund survey out today says. Hospitals and other health care services contribute 8.5% of greenhouse gas emissions, as the report notes and STAT’s Karen Pennar has described. Reducing that number could be significant, whether it’s achieved by lowering carbon dioxide output or tying executive compensation to progress toward a greener future, respondents said. Other findings:

  • Three in four clinicians say they themselves should act to reduce their environmental impact, at work and at home.
  • Respondents in leadership said most hospitals are reducing energy consumption (69%) and waste (76%) or setting emissions targets (35%).
  • About six in 10 said a prospective employer’s policies and actions on climate change would affect their decision to apply for a job.

FDA OKs replacing a cancer-causing sterilizer with a new chemical

Did you know that ethylene oxide, the chemical used to sterilize half of all medical devices in the U.S., is known to cause cancer? Research dating to the 1970s has connected emissions from the sterilize to higher cancer rates. The FDA has known this for years, but just this month, the regulatory agency said a safer gas, vaporized hydrogen peroxide, is a legitimate way to decontaminate devices. It’s a small step, but one that will push the medical device industry away from the carcinogenic chemical.

The EPA will finalize restrictions on ethylene oxide in March and medical device manufacturers will have 18 months to comply. It won’t be a simple swap for a health care system that relies on the older chemical to sanitize such critical medical devices as catheters, stents, pacemakers, and syringes. Hydrogen peroxide is more challenging to work with, as the gas condenses when it cools, for example. STAT’s Lizzy Lawrence takes a closer look.

Dog Aging Project's founders hope to raise $50 millionFounder-Dr.-Matt-Kaeberlein-with-Dobby-and-Chloe-1600x1396

The Dog Aging Project, which researchers say could yield promising leads for human longevity research, is at a critical crossroads after its NIH grant funding was not renewed. But as STAT’s Deborah Balthazar puts it, Daniel Promislow and Matt Kaeberlein (above, with his dogs Dobby and Chloe), co-founders of the massive project, aren’t ready to roll over and play dead yet. Here’s what they told her.

Given the decision to not renew funding for your project, how are you thinking about the progress made so far?
Promislow: What we’re trying to do is a kind of forever study. Our goal is to follow these dogs for their lives, and to continue to enroll new dogs to be able to ask new questions, [but] the world of NIH runs on a five-year funding cycle.

Kaeberlein: There have been significant contributions to the scientific literature, including the clinical trial. So we have a double-blind, randomized, placebo-controlled clinical trial of a drug called rapamycin. Truly, the first-ever clinical trial in dogs or humans to assess the effect of a drug on the biology of aging, with lifespan as the endpoint, and healthspan as the secondary endpoint.

A rehabilitation researcher transformed by his daughter's traumatic brain injury

Lindsay Sulzer 

James Sulzer hopes no one else comes to know the drastic consequences of a neurological injury the way his family has. In 2020, his almost 4-year-old daughter Livie sustained a severe traumatic brain injury when a tree branch fell on her head in their backyard, devastating the whole family. After five months in the hospital, she had become cognitively impaired and couldn't walk, talk, or do any activities on her own. As a rehabilitation researcher for two decades, Sulzer found his professional background helped far less than he had expected. 

“The emotional, logistical, and physical toll of Livie’s care, coupled with the realization of just how limited my research expertise is to help her, has been soul-sapping,” he writes in a STAT First Opinion. “We need to include input, experiences, and insights from people affected by conditions like brain injury in the entire research process.” Read more.

Older patients spend three weeks a year getting health care away from home

Back in June 2020, I visited a cancer center with a patient participating in a clinical trial to treat her ovarian cancer. Because Covid-19 was fairly new and vaccines were still far away, great efforts were made to streamline visits so no patient was exposed longer than necessary to other people. That came to mind as I read a study in this week's Annals of Internal Medicine tracking just how much time older patients who still live independently spend getting health care outside their homes.

The average was three weeks a year in the cross-sectional study of more than 6,500 adults 65 and older (and 50 days for 11% of them). Here’s what made me recall the cancer story: About half of the older patients’ test days and imaging days were not on the same days as office visits, which doesn’t sound like streamlined care. But an editorial hints that could change: “Policymakers and health care systems are increasingly using measures that more fully capture what matters most to many older adults — the amount of time they spend outside of the health care system.”

Black people enrolled in Medicaid have more preventable hospitalizationsrwjf477094

Urban Institute

Not every hospital admission has to happen. They can often be prevented — in up to 3.5 million cases, one annual estimate says — if patients can find timely, high-quality outpatient care. A new analysis from the Urban Institute has found that Black people enrolled in Medicaid have higher rates of preventable hospitalizations than white people covered by Medicaid. Looking at 21 U.S. states, three previously diagnosed conditions were most likely to result in a  hospital stay: asthma or chronic obstructive pulmonary disease, diabetes, and heart failure. 

Hospitalization rates were higher for people insured by Medicaid through the Supplemental Security Income program, which is based on a qualifying disability, but for heart disease in particular, Black Medicaid enrollees were more likely to have a preventable hospitalization than white enrollees, with or without SSI, the report found. “These findings suggest a need to improve access to outpatient care to effectively manage chronic conditions,” the report concludes.
