U.S. medical 'trash' saving lives abroad

AppId is over the quota

(CNN) -- Doctors will often prepare for surgical procedures by opening instrument and supply kits that contain up to 100 items.

Many of these items, such as scalpels, needles or sponges, go unused; they're just not needed for that particular procedure. But because of government or hospital regulations in the United States, they are frequently thrown away, even when they are still wrapped.

"There are thousands of tons of medical supplies thrown away every day that are unused or clearly reusable," said Dr. Bruce Charash, a cardiologist in New York.

Fortunately, some nonprofit organizations, including Charash's Doc2Dock group, are finding ways to salvage these items and get them to people who need them desperately around the world.

In Uganda, for example, many medical facilities lack the necessary supplies and equipment needed to perform surgery. The outlook is normally grim for children such as Priscilla, who was diagnosed with a brain tumor when she was 7.

But one Ugandan hospital, CURE Children's Hospital in Mbale, has been able to operate on Priscilla and more than 1,100 other kids thanks to its partnership with MedShare, a nonprofit that collects surplus supplies and equipment from the U.S.

"Brain tumors happen to children all over the world," said Derek Johnson, executive director of CURE Uganda. "The main difference in Uganda is that there are so few resources. But we were able to save Priscilla with supplies we get from MedShare."

'Our trash becomes their riches'

In the United States, surgical supplies aren't the only useful medical items tossed away.

Richard St. Denis, one of the Top 10 CNN Heroes of 2011, collects discarded wheelchairs through his nonprofit, World Access Project. With help from another U.S.-based nonprofit, Hope Haven, the wheelchairs are refurbished by senior citizen volunteers and prison inmates in Iowa before being shipped to rural Mexico.

St. Denis first visited Mexico in 1997, and he met many people with disabilities who didn't have access to wheelchairs, walkers or canes.

"I was shocked to see people using branches for crutches, being pushed in wheelbarrows and crawling," said St. Denis, who lost the use of his legs during a skiing accident in 1976.

Now, he has a permanent residence in Mexico and continues to do everything he can to help the people around him.

"We want to distribute the more than 75,000 wheelchairs we estimate get thrown away in the U.S. every year," he said. "What we call our trash becomes their riches, and it makes an incredible difference in their lives."

A win-win for everyone

In addition to saving lives, there's another benefit to sending unused supplies abroad.

"We are diverting a certain amount of waste that would be landfilled," said Dr. William Rosenblatt, a professor of anesthesiology at Yale University School of Medicine and founder of the nonprofit Remedy.

"At the end of a surgical procedure, our staff surveys the scrub table where the kit items remain and segregates all the materials that have been unused," Rosenblatt said. "It gets sent down to (a) decontamination area, and Yale undergraduate students sort through it and take what is useful. From here, it is packaged in bulk and given to a charity to be taken overseas."

Sometimes, perfectly good equipment is thrown away.

"Why would (hospitals) throw out a working sonogram machine or a working hospital bed?" Charash said. "One, it's not pretty enough. Secondly, there might be new technology available. In general, no one wants to use a 2005 (model) if a 2012 is available."

Occasionally, a hospital will simply switch brands and get rid of an entire line of unused items.

Supply manufacturers have been known to send items directly to the nonprofits if a box is so much as dented in transport -- items that could mean life or death for an individual in a Third World hospital.

The need greatly outstrips the supply

"On my first trip to Africa, the hospital director showed me a patient dying of malaria," Charash said. "He showed me a room with hundreds of bottles of medicine that would save his life, but (the medicine was) not given to him because they had no intravenous lines.

"That day, our Doc2Dock container arrived with reconstituted IV lines and 3,000 to 4,000 syringes. The doctor got an IV line, the patient got the medicine and was saved."

But while unused medical equipment is saving many people around the world, only a small percentage of hospitals ever actually receive these items.

"If you look at the volume of appeals we get versus the amount we are able to help, we are able to find funding for a quarter of the bona-fide projects," said David Pass, chief advancement officer for MedShare. "There is a great need out there."

The effort to find more funding is worth it, said Tanya Weaver of the American Foundation for Children with AIDS. Her nonprofit works in four African countries and has been able to help more than 100,000 people there thanks to surplus medical supplies from a couple of hospitals.

"If we can do this with the help of just two U.S. hospitals, imagine how many more could be served if others got involved," Weaver said.

Mammograms don't save as many lives as women think

CHICAGO | Tue Oct 25, 2011 3:02pm EDT

CHICAGO (Reuters) - Many women who have survived breast cancer often say it was a mammogram that "saved their life," a powerful testimonial that can encourage other women to get regular breast cancer screening tests.

But what are the chances that the test actually saved a woman's life? Not that great, according to a new analysis published in the Archives of Internal Medicine on Monday.

"The numbers suggest that at most, 13 percent of those diagnosed with breast cancer have been helped. That means the other 87 percent have not been helped," Dr. Gilbert Welch of Dartmouth College, who led the study, said in a telephone interview.

"That is important when we keep hearing these stories from breast cancer survivors," he said.

Welch said women who tell their stories about surviving breast cancer can be a powerful inducement for other women to get tested for breast cancer, and as mammogram technology has improved, the chances are even greater that doctors will find something suspicious.

But early detection for some women may not be much of a benefit, especially if a cancer is slow growing, Welch and colleagues say. And many women may be diagnosed and treated for a cancer growing so slowly it might never have caused any symptoms or threatened their lives.

The findings add new fodder to the simmering debate over the benefits of screening healthy people for cancer. Earlier this month, the government-backed U.S. Preventive Services Task Force recommended that healthy men not get a common blood test for prostate cancer, causing an uproar among cancer specialists who fear more men will die from prostate cancer.

In 2009, the same group recommended that women under 50 not get routine mammograms. For women 50 and older, it recommended the test only every other year, rather than yearly, causing an outcry from breast cancer advocacy groups.

But screening tests have both benefits and risks, says Welch, who views the current debate as positive for patients who are starting to think more about the risks of screening.

An earlier study by Welch found that routine screening for prostate cancer has resulted in as many as 1 million American men being diagnosed with tumors who might otherwise have suffered no ill effects from them.

In the latest study, Welch and colleagues looked to see how much mammography reduces deaths from breast cancer.

They found that for 50-year-old women whose breast cancers were diagnosed by a mammogram, there was a 13 percent chance that the screening test saved her life.

The question, then, becomes how to preserve the benefit of mammogram without exposing so many women to the harms of overdiagnosis -- which include being treated for cancers that might not cause harm, Welch said.

He said breast cancer screening technology has become better and better at spotting tiny cancers on the assumption that the earlier a cancer is detected, the better the chances of cancer survival.

But Welch said as treatments for breast cancer get better, the need for very early diagnosis is less great.

"For years we've been looking harder and harder for cancer. I think the time has come to ask the question, 'What if we looked a little less hard?'"

Dr. Timothy Wilt of the Minneapolis Veterans Administration, who wrote a commentary on the findings in the same journal, said the study gives doctors science-based information to share with patients, who are often influenced by anecdotes.

"Because survivor stories are often so powerful, but inaccurate, they can result in people making healthcare decisions that are not science based and may be wrong," he said.

Mammograms Only Occasionally Save Lives, Analysis Finds

AppId is over the quota
AppId is over the quota

Some doctors and public-health experts have stirred controversy in recent years by arguing that aggressive breast-cancer screening does more harm than good. Many health professionals disagree, but perhaps the most compelling critics of the less-is-more philosophy are the many breast cancer survivors who claim that a routine mammogram saved their lives.

These survivor anecdotes — which often turn up in the media — may be causing the public to overestimate the true value of mammograms, a new study suggests. In an analysis published this week in the Archives of Internal Medicine, researchers at Dartmouth estimate that only about 1 in 8 women whose breast cancer was identified during a routine mammogram actually owe their lives to the screening.

This estimate doesn't mean that women shouldn't bother to get mammograms, but it does suggest that overly frequent screening can result in overtreatment, the authors say. Many tumors identified during routine mammograms would have grown very slowly (if at all) and would never have threatened a woman's life, says Dr. H. Gilbert Welch, one of the coauthors of the analysis.

"A certain fraction of women are being treated for a disease that was never going to bother them," says Dr. Welch, a professor of medicine at the Dartmouth Institute for Health Policy and Clinical Practice, in Hanover, N.H.

LIST: 25 Breast Cancer Myths Busted

The U.S. Preventive Services Task Force (USPSTF), a government advisory panel that issues guidelines on cancer screening, recommends that women start having mammograms every other year when they turn 50, while women who have risk factors for breast cancer should talk with their doctor about starting screening earlier. (Prior to 2009, the panel recommended annual mammograms for all women beginning at age 40.) A large study published last week found that biennial screening resulted in fewer false alarms and unnecessary biopsies than annual screening.

The results of the new analysis should reassure women with average breast-cancer risk that it's safe to wait until age 50 — or later — to begin mammograms, Dr. Welch says. However, he adds, women who would prefer to undergo screening earlier or more frequently should do so if it will make them more comfortable. "It's generally a really close call, and how patients feel really matters," he says.

To investigate the value of mammography in terms of lives saved, Dr. Welch and his colleague, Brittney Frankel, used breast-cancer data from the National Cancer Institute and the Centers for Disease Control and Prevention to calculate a woman's likelihood of developing breast cancer over a 10-year period, the likelihood that the cancer would have been detected by mammography, and a woman's risk of dying from breast cancer over a 20-year period.

LIST: Simple Things That Could Cut Your Breast Cancer Risk

Using the relevant data for a hypothetical 50-year-old woman who received a breast cancer diagnosis following a routine mammogram, the researchers estimate that the probability that the mammogram will be responsible for saving her life is about 13%. And even that estimate may be high, they say: mammograms prevent fewer deaths today than they did 20 or 30 years ago (thanks to better treatment that has made early detection less crucial), so the actual probability could be as low as 3%.

"Women need to understand their trade-offs here," Dr. Welch says. "The reason to be screened isn't because you've heard a lot of survivor stories. Some of those women have not benefited [from screening]."

Dr. Timothy Wilt, a researcher at the Minneapolis Veterans Affairs Center who specializes in chronic disease outcomes, says that breast-cancer diagnosis and treatment can even be harmful in some cases. Radiation treatment, for instance, can cause disfigurement, accelerate blockage of arteries in the heart, and increase the risk of secondary cancers, he says.

LIST: How to Help a Loved One Cope With Breast Cancer

"Looking harder and treating more doesn't always help people live longer and live better," says Dr. Wilt, who coauthored an editorial accompanying the study and is a member of the USPSTF. The push toward less screening "is not about rationing care," he adds. "It's about making good health care decisions to help patients live better and live longer."

Dr. Laura Esserman, the director of the breast care center at the University of California, San Francisco, says that doctors and women should shift their focus away from breast-cancer screening and toward prevention. For instance, Esserman says, women can reduce their risk of breast cancer by maintaining a healthy weight, exercising regularly, and minimizing their alcohol consumption.

"Mammography has some value," she says, "but I think it's pretty clear that the public has overvalued it and a lot of people who push it have overvalued it."

Midwife shortages 'risking lives'

AppId is over the quota
AppId is over the quota
15 September 2011 Last updated at 04:59 GMT By Jane Hughes Health correspondent, BBC News Midwife with mother and baby Midwives say shortages could harm patients Parts of England are facing big midwife shortages, putting mothers and babies at risk, midwives have said.

The Royal College of Midwives says a 22% rise in births over 20 years has led to shortfalls across England, but some areas are worse than others - it highlights the East Midlands and East.

The RCM wants 4,700 more midwives and says the prime minister has backed away from a pledge to raise numbers.

The Department of Health said record numbers of midwives were being trained.

Midwives say births are becoming increasingly complex because of growing numbers of obese and older mothers-to-be, who often need extra support.

The Royal College of Midwives says the extra 4,700 midwives are needed across England to keep pace with the added pressures.

And it says a new analysis of midwife numbers across England reveals big variations - with limited shortages in some areas and serious shortfalls in others.

The calculations were done by measuring the number of midwives in an area against the number of babies born there. The RCM estimates that one midwife is needed for every 28 hospital births and 35 births in a midwife-led unit or at home.

The North East and North West of England had a shortfall of less than 10%.

But according to the figures, the East Midlands and East of England need 41% more midwives, and the South East is also more than a third short of staff.

The college says the disparity is down to different levels of investment in different areas; women living in places with bigger shortfalls are at risk of having less choice over how and where they give birth.

It says Scotland, Wales and Northern Ireland do not have midwife shortages at the moment.

'Critical shortfalls'

"This is a real problem in England," said Cathy Warwick, RCM General Secretary.

"We believe women should have the same choice over giving birth wherever they live. Once you get to really critical shortfalls, maternity services won't be safe."

It's a sentiment echoed by the head of midwifery at Wansbeck hospital in Northumberland, where they say they have enough staff to offer high-quality care.

Janice McNichol has delivered more than 1,000 babies in her career, and prides herself on making sure every mother has a positive experience.

"It's about safety and quality of care," she said. "Making sure midwives are there when mum needs them, to answer questions and help her through the process."

The charity Action against Medical Accidents, AVMA, said the situation in some areas was desperate.

"Having a baby should be the happiest time in a couple's life, but failure to deal with this problem is all too often turning it into a tragedy," said AVMA chief executive Pater Walsh.

"Maternity services should be the NHS's first priority for improving patient safety and having enough trained midwives is an absolute must."

The Department of Health said midwife numbers had risen and record numbers are being trained.

A spokesperson said all mothers and their babies should expect and receive consistently excellent maternity care.

HEALTH MANAGEMENT. Thousands of lives saved are cheap generic alone in Sweden

A major new international study, the researchers from the Sahlgrenska Academy at the University of Gothenburg and Sahlgrenska University Hospital showed that aspirin, statins, beta-blockers, and ACE inhibitors are much too rarely required. They are cheap, preventive drugs that could prevent a large number of deaths from heart attacks and strokes.
The result of research collaboration by 17 countries, who study in the highly revered medical journal is published in the Lancet.
The study shows aspirin, Statins (cholesterol-lowering drug), beta blockers and ACE inhibitors as drugs, that should be used far more often.
"That has exhausted the patent where, are generic preparations," says Annika Rosengren, Professor of medicine at the Sahlgrenska Academy at Göteborg University and consultant at Sahlgrenska University Hospital. "they're cheap, and proven and effective, and there is no reason that they much more frequently patients prescribe, in the zone." "In Sweden alone they have saved thousands of lives per year."
The results come from a major international study with more than 150,000 adults in low, medium and high income countries around the world. Only a quarter of those, the heart attack or stroke would have suffered aspirin (or similar), only one-fifth had beta blockers, and only a seventh drugs reduce your cholesterol taken had. The lowest figures came from countries with low income. The study also shows that women of less often than men these medicines.
"The results indicate a genuine need systematic car to understand why these cheap drugs are insufficiently used worldwide", says Professor Salim Yusuf of McMaster University in Canada, who led the study. "This is a global tragedy and provides a massive missed opportunity to help millions of people with cardiovascular disease at a very low cost."
The pure study (potential urban rural epidemiology study) 17 countries are: Canada, Sweden, U.A.E., Argentina, Brazil, Chile, Malaysia, Poland, South Africa, Turkey, China, Colombia, Iran, Bangladesh, India, Pakistan and Zimbabwe.
