Hello and welcome to episode 455 of Morning Medical with Doctor Chow.
0:05
I'm your host, Doctor Chi-Ming Chow.
0:09
Today, we're diving into a rather unsettling development in the healthcare sector, where
0:15
artificial intelligence is making waves, and not necessarily in a good way.
0:20
We're discussing a story that has emerged from the Bronx, New York, where Montefiore Medical
0:25
Center has made a controversial decision to replace twelve nurses with artificial
0:30
intelligence software.
0:32
This decision has stirred significant concern among the nursing staff and the New York State
0:40
Nurses Association, or NYSNA, who argue that this is just the "tip of the iceberg." The
0:46
nurses were part of the hospital's utilization review team, a group responsible for ensuring
0:51
that patient care is necessary and appropriately managed.
0:55
This move comes shortly after a February agreement between the nurses' union and the
0:59
Montefiore hospital system, which had ended a nearly month-long strike.
1:04
Ajita Mathew, a registered nurse with 36 years of experience, was one of those impacted by the
1:11
decision.
1:12
She received a letter from the hospital's Labor and Employee Relations department stating that
1:18
her position would be eliminated within 45 days.
1:22
The hospital assured her that they would work closely with her to find a suitable position
1:27
according to the collective bargaining agreement, but the uncertainty remains
1:31
unsettling for many.
1:34
Marilyn Shuler, another long-term nurse with 39 years at the hospital, expressed concerns about
1:41
the lack of clarity regarding who or what would be responsible for sending necessary clinical
1:47
information from patients' charts to payers.
1:50
She highlighted the vast knowledge and experience that utilization review nurses
1:54
possess, which cannot simply be reduced to mere clicks or algorithms.
2:00
New York City Council member Shirley Aldebol has also voiced her worries.
2:04
She fears that replacing the complex clinical judgment of real nurses with artificial
2:08
intelligence could lead to dropped cases, missed diagnoses, and other critical patient
2:13
services being denied.
2:15
It's a sentiment echoed by Judy Sheridan-Gonzalez, an emergency department
2:20
nurse and former NYSNA president, who emphasized the invaluable role of human beings
2:26
in advocating for patients' needs.
2:28
Sheridan-Gonzalez pointed out that while algorithms process raw data, they lack the
2:34
ability to consider a patient's gender, race, ethnicity, cultural needs, physical needs, and
2:41
clinical needs.
2:42
She stressed that there's so much more to patient care than can be captured by data
2:47
alone.
2:48
It's about understanding complex conditions, providing the necessary support for patients at
2:52
home, and ensuring their well-being post-discharge.
2:56
The claim that this decision violates the union agreement, which mandates discussions with the
3:02
union before implementing artificial intelligence, has added another layer of
3:06
controversy.
3:07
However, Montefiore Health System's spokesperson, Joe Solomonese, has dismissed
3:13
these claims as inaccurate and misleading, stating that the institution is committed to
3:18
investing in new technology to ensure the best care for patients.
3:23
Yet, the nurses remain unconvinced, especially given the recent changes in the utilization
3:29
review process involving artificial intelligence software from Datavant.
3:34
This company, which recently settled a class action lawsuit following a significant data
3:39
breach, has only added to the skepticism surrounding the move.
3:44
Shaiju Kalathil, a member of NYSNA's executive committee, emphasized that nurses are not
3:49
against technology per se.
3:51
However, they are concerned when hospitals introduce new technologies without clear
3:55
evidence of benefits for patients and healthcare workers.
3:59
The fear that patient care might suffer and jobs could be lost is very real.
4:04
In essence, the nurses are calling for a halt to the layoffs, advocating for the hospital to
4:08
retain licensed nurses for utilization reviews, and urging discussions on how artificial
4:13
intelligence can support rather than replace the human touch in healthcare.
4:17
It's a complex issue that raises important questions about the future of healthcare and
4:22
the role of technology within it.
4:25
The heat index is a crucial metric that many of us have likely heard about during extreme
4:31
weather conditions.
4:33
It measures how hot the air actually feels by factoring in both the temperature and the
4:37
humidity levels.
4:39
This is why you'll often hear that it "feels like" a certain temperature, which is usually
4:45
higher than the actual temperature.
4:48
For instance, if the temperature in Central Park is 98 degrees Fahrenheit, the heat index
4:54
might register at 105 degrees Fahrenheit.
4:58
This difference is because higher humidity levels mean less perspiration can evaporate
5:03
from our skin, making it feel much hotter than the actual air temperature.
5:09
But what exactly is the heat index, and how did meteorologists come to understand and calculate
5:14
it?
5:15
The heat index is essentially a more complex way of acknowledging the old adage, "it's not
5:20
the heat, it's the humidity." The formula used to calculate the heat index involves both
5:25
temperature and relative humidity in a rather intricate equation.
5:29
To give you an idea, it includes terms like temperature times 2.049, humidity times 10.143,
5:38
and several other combinations of temperature and humidity, both squared and multiplied
5:43
together, resulting in a final number that reflects the perceived heat.
5:49
This formula was developed by Lans Rothfusz, a retired meteorologist from the National Weather
5:54
Service, back in 1990.
5:57
At the time, he was an intern at the Weather Service's Southern Region Headquarters in Fort
6:02
Worth, Texas.
6:03
Rothfusz, now 66 years old, recalls that his work on the heat index was part of his early
6:08
career contributions to meteorology.
6:11
His efforts were recognized when he received the National Weather Association's operational
6:16
achievement award in 2014.
6:19
Understanding the heat index is vital, especially during heat waves when the perceived
6:24
temperature can lead to serious health risks like heat exhaustion or heat stroke.
6:28
By being aware of the heat index, individuals can take necessary precautions to stay safe,
6:34
such as staying hydrated, seeking shade, and avoiding strenuous activities during peak heat
6:39
hours.
6:40
It's a reminder of how scientific calculations and meteorological insights intersect to
6:46
provide us with tools to better understand and navigate the challenges posed by extreme
6:51
weather conditions.
6:54
Doctor Peter Hotez, an infectious disease specialist based in Houston, is taking no
6:59
chances when it comes to mosquito bites, especially with the early onset of West Nile
7:03
virus season.
7:05
Despite the sweltering heat, he opts for early morning walks dressed in a t-shirt, a hooded
7:10
sweatshirt, a hat, sweatpants, socks, and sneakers.
7:14
It's not the heat that concerns him but rather the mosquitoes, as he is keen to avoid
7:20
contracting what Doctor Anthony Fauci, former director of the National Institute of Allergy
7:25
and Infectious Diseases, described as "the sickest I’ve ever been" following his own bout
7:31
with West Nile virus in 2024.
7:35
The United States Centers for Disease Control and Prevention has reported that this year
7:40
marks the earliest start to West Nile virus season in over two decades.
7:45
Typically, cases begin to rise in July and peak in August and September.
7:50
However, as of June 30, states have already reported 48 cases, with 38 of those involving
7:57
neuroinvasive disease, where the virus affects the brain.
8:01
This is a concerning trend, as the last time the season started this early, in 2004, it
8:07
resulted in over 2,500 cases and 100 deaths by year-end.
8:13
Doctor Lyle Petersen, director of the Division of Vector-Borne Diseases at the CDC’s National
8:20
Center for Emerging and Zoonotic Infectious Diseases, cautions that the actual number of
8:25
West Nile virus cases is likely much higher.
8:28
Many individuals with the virus do not develop symptoms severe enough to seek medical care,
8:34
leading to underreporting.
8:36
Petersen estimates that the real number of cases could be thirty times higher than those
8:41
reported.
8:43
The CDC has noted West Nile activity in 23 states, the highest number this early in a
8:48
decade.
8:50
This activity includes positive tests in mosquitoes and other animals.
8:55
In particular, Maricopa County in Arizona is experiencing a significant spike, with 29
9:01
confirmed cases and four deaths reported so far this year.
9:06
This is a stark increase from the 13 cases and one death reported in the same period last
9:12
year.
9:13
West Nile virus primarily affects adults over 60, who are at greater risk for severe
9:18
complications such as swelling of the tissues around the brain and spinal cord.
9:22
Doctor Daniel Pastula, chief of neuro-infectious diseases and global neurology
9:27
at the University of Colorado-Anschutz, emphasizes the importance of mosquito bite
9:32
prevention.
9:33
Unfortunately, there are no specific treatments for West Nile virus, although promising
9:38
early-stage clinical trials have been conducted for vaccines.
9:43
Preventative measures are crucial, particularly in high-risk areas like Arizona.
9:47
These include eliminating standing water around homes, using larvicides in ponds, employing
9:53
traps for adult mosquitoes, and ensuring homes are cooled with air-conditioning.
9:58
People should also treat their clothing with permethrin and use EPA-registered bug
10:03
repellents, especially during peak mosquito activity times such as sunrise and sunset.
10:09
Doctor Pastula also advocates for greater federal support for local mosquito control
10:13
programs and increased funding for vaccine development.
10:17
He stresses that improving vaccine development for West Nile virus is vital to reducing the
10:22
disease's burden on public health.
10:25
Our final segment today takes us to Windsor, Ontario, where a concerning trend has emerged
10:32
involving the street drug supply.
10:34
The Welcome Centre Shelter for Women and Families has raised alarms about a dangerous
10:40
substance appearing in local fentanyl supplies—an animal tranquilizer known as
10:45
medetomidine.
10:46
This non-opioid drug, often referred to as "rhino tranq," is typically used by
10:53
veterinarians to sedate large farm animals.
10:57
Anastasia Adams, the harm reduction program coordinator at the shelter, emphasizes the
11:02
risks posed by this tranquilizer.
11:05
She notes that its presence in the street supply leads to prolonged sedation, which can
11:10
resemble symptoms of drug poisoning or overdose, but unlike opioids, users continue
11:15
breathing.
11:16
Unfortunately, this makes it difficult to reverse the effects with naloxone, a
11:20
life-saving medication used to counteract opioid overdoses.
11:25
The shelter has taken to social media to warn the public about the presence of medetomidine
11:31
in Windsor's unregulated fentanyl supplies.
11:34
Adams highlights the increased risk of assaults and thefts for individuals who cannot wake up
11:40
due to the tranquilizer's effects.
11:43
This issue is not confined to Windsor, as Health Canada has observed a nationwide uptick
11:49
in medetomidine detection in opioid supplies over the past few years.
11:55
Health Canada's Drug Analysis Service, which monitors drugs submitted by law enforcement and
12:00
public health partners, reports that medetomidine was rarely detected before 2023
12:06
but has since become more prevalent.
12:09
Although naloxone remains effective against opioids like fentanyl, it cannot counteract
12:14
medetomidine, presenting a new challenge for harm reduction efforts.
12:20
In response to this growing threat, the Welcome Centre is advocating for a well-informed
12:25
community to support harm reduction.
12:28
Adams advises individuals to use substances in the company of trusted friends, in safe
12:33
environments, and to test their supplies if possible.
12:37
The shelter provides resources for women to test their substances, helping them identify
12:42
potentially harmful additives.
12:44
However, the closure of safe consumption sites across Ontario, including Windsor's site in
12:49
January 2024, has complicated these efforts.
12:53
Adams argues that these closures run counter to harm reduction principles, which rely on
12:58
data-driven approaches rather than stigmatizing individuals who use substances.
13:04
She stresses the importance of maintaining open dialogues with users to support their health
13:10
and safety.
13:12
As we conclude today's episode, it's clear that the intersection of healthcare, technology, and
13:18
community efforts remains a dynamic and challenging landscape.
13:22
Whether it's the role of artificial intelligence in healthcare, understanding the
13:26
heat index during extreme weather, or addressing the complexities of drug use and
13:31
safety, staying informed is crucial.
13:33
Thank you for joining me on this journey through today's medical news.
13:37
Until next time, stay safe and stay informed.
