Anti-PVC Push In Health Care
Grows
Hospitals and public health professionals are
pushing to find alternatives to soft-plastic PVC found in IV bags, tubing,
neo-natal masks -- even flooring and carpeting.
These products are softened with additives
called plasticizers. Most often, these plasticizers contain phthalates, which
have been restricted in toys in the United States because of fears they disrupt
the delicate body's delicate chemical signaling system.
The American Public Health Association this
week passed a resolution urging facilities such as hospitals, schools and
nursing homes reduce the amount of PVC they use, especially with phthalates.
"These additives have toxic
characteristics and are gradually released posing risks to infants, children
and other vulnerable populations," the APHA said in its resolution.
The APHA counts among its 25,000 members
federal, state and local public health officials, epidemiologists, academics
and others.
"This is an issue whose time has
come," said Brenda Afzal of the APHA's governing council. "There is a
preponderance of evidence that this is a problem."
Allen Blakey, a spokesman for the Vinyl
Institute, a trade organization, said the resolution was misguided.
"I think it's based on old, outdated
information -- misinformation. I don't think it reflects at all what science is
saying about PVC. I think I would call it more of a political document than a
public health document," Blakey said.
The resolution comes on the heels of a move
by five large purchasing companies representing 1,100 hospitals and $135
billion in buying power to push manufacturers of medical products to make them
with safer chemicals.
The group, called Practice Greenhealth,
agreed in October to ask all suppliers a series of questions including whether their
products contain PVC.
"I think it's going to be one of the
products that over the next five to ten years the health care sector is going
to want to phase out, as it did mercury (in thermometers), and it will
stimulate significant innovation toward safer and more sustainable
plastics," said Gary Cohen, president and co-founder of Health Care
Without Harm, which organized the coalition of hospital purchasing companies.
Cohen noted that companies had already
developed PVC-free IV bags and tubing and pointed to several large hospital
chains as signs PVCs days are numbered.
Kaiser Permanente, one of the nation's
largest not-for-profit health plans, has committed to eliminated PVC from its
hospitals. Kaiser Permanente spends $1 billion a year on medical products and
equipment alone.
Catholic Healthcare West in 2005 converted
its 30 hospitals to PVC and phthalate free IV bags and tubing.
Blakey, of the Vinyl Institute, said PVC
remained the most widely used material in blood bags and tubings.
"It's just got great properties. It's
flexible. It's kink resistant. It can be steam sterilized. It can be
frozen," Blakey said.
Every year, almost 15 billion pounds of PVC
are produced in the United States for pipes, building materials and a myriad of
other uses. In consumer goods, it's marked with the recycling code #3.
Production of PVC results in emissions of
vinyl chloride, classified by the Environmental Protection Agency and the
Department of Health and Human Services as a known human carcinogen.
Incineration of PVC waste releases chemicals called dioxins, also carcinogens.
A growing body of research has found
phthalates, used to soften PVC, are linked to health problems.
Among them:
A Columbia University study published in
September finding prenatal exposure to phthalates linked to decreased mental
and motor development at age three.
In its resolution, the American Public Health
Association cited studies linking phthalate exposure to asthma and reproductive
problems.
The resolution urged local, state and federal governments
to educate administrators and purchasing staff "about PVC hazards and
safer alternatives in schools, day care centers, medical care facilities,
nursing homes, public housing, facilities for special needs and the disabled,
and other facilities with vulnerable populations."
