If you've ever had a surgical procedure, you know it can often mean a high hospital bill. Now, more people are turning to surgery centers for a lower cost.Sandi Bowen is one of those people.Something as simple as picking out a shirt is more challenging for Bowen than she ever thought it'd be. On Easter, she found a lump in her breast. Doctors told her it was cancer."It was very very very confusing," Bowen says. "It still is. It brings tears to my eyes, because I don't understand how I got it."Instead of a lumpectomy, she decided to remove her entire breast. And instead of going to a hospital for breast reconstruction, Bowen opted for the Kaiser Permanente Ambulatory Surgery Center, where she got the surgery. In less than 24 hours, she was back home recovering.  "I felt very special," Bowen says. "They were there every time I moved. They came in and talked to me, even goofed around with me."Dr. Mike Sawyer, the director at the center, says they've worked hard to address concerns regarding patient care."If it's a patient that just needs physicians to kind of come to the bedside, and maybe we have to have some kind of intervention, we're able to do that because are here and we are present," Dr. Sawyer says. "On site, as they say. If it's really something that requires a higher level of care, that again allows us to do a pretty quick transfer process over to one of our partner hospitals."Compared with hospitals, Kaiser Permanente says its patients are seeing an average cost savings of 30 percent on their procedures. It can be anything from simple orthopedic procedure to joint procedures.However, Dr. Sawyer says there are important questions you need to ask before determining if a surgery center is the best option for you."Does your physician feel comfortable with this operation there?" Dr. Sawyer says. "Have you and your physician discussed all the ramifications of that procedure? And then what sort of plans does that ambulatory surgery center have if you were required a higher level of care?" 2037

How accurate are the coronavirus tests used in the U.S.?Months into the outbreak, no one really knows how well many of the screening tests work, and experts at top medical centers say it is time to do the studies to find out.When the new virus began spreading, the Food and Drug Administration used its emergency powers to OK scores of quickly devised tests, based mainly on a small number of lab studies showing they could successfully detect the virus.That’s very different from the large patient studies that can take weeks or months, which experts say are needed to provide a true sense of testing accuracy.The FDA’s speedy response came after it was initially criticized for delaying the launch of new tests during a crisis and after the Centers for Disease Control and Prevention stumbled in getting its own test out to states.But with the U.S. outbreak nearly certain to stretch on for months or even years, some experts want the FDA to demand better evidence of the tests’ accuracy so doctors know how many infections might be missed.There have been more than 2 million confirmed coronavirus cases in the U.S. and more than 115,000 deaths, according to data compiled by Johns Hopkins University. Cases in nearly half of U.S. states are rising.In recent weeks, preliminary findings have flagged potential problems with some COVID-19 tests, including one used daily at the White House. Faulty tests could leave many thousands of Americans with the incorrect assumption that they are virus-free, contributing to new flare-ups of the disease as communities reopen.“In the beginning, the FDA was under a lot of pressure to get these tests onto the marketplace,” said Dr. Steven Woloshin of Dartmouth College, who wrote about the issue in the New England Journal of Medicine last week. “But now that there are plenty of tests out there, it’s time for them to raise the bar.”The FDA said in a statement that it has already asked multiple test makers to do follow-up accuracy studies, although it didn’t say for how many of the more than 110 authorized screening tests. The agency also said it is tracking reports of problems. Accuracy has also been an issue with blood tests that look for signs of past infections.No screening test is 100% accurate. So details on accuracy are routinely provided for tests of all types, including seasonal flu, hepatitis, HIV and cancers. For example, rapid flu tests are known to miss 20% or more of all cases, a factor doctors weigh when treating patients who have symptoms but test negative.For now, most COVID-19 tests in the U.S. don’t give data on real-world performance, including how often the tests falsely clear patients of infection or falsely detect the virus. That information is lacking for all but a few of the roughly 80 commercial screening tests available, according to an Associated Press review.The government’s emergency authorization process “requires a lower level of evidence,” the agency said. Makers need only show that a test “may be effective” instead of the usual requirement to demonstrate “safety and effectiveness.” They would have to meet that higher threshold once the U.S. government declares the emergency over.Many of the commercial test makers submitted results from 60 samples, the minimum number required and mostly used lab-produced specimens of the virus. The FDA now recommends the use of nasal swabs or other real samples from people screened for coronavirus.Experts say larger patient studies patients are needed to assess a test’s true performance.Lab testing bears little resemblance to actual — sometimes imperfect — conditions at hospitals, clinics and testing sites noted Dr. Robert Kaplan of Stanford University.“You’re testing people in parking lots, the patients themselves are extremely anxious and often unable to follow instructions,” said Kaplan, a former associate director of the National Institutes of Health.Kaplan and others say those differences could explain why some tests are not performing as expected.Last month, the FDA warned doctors of a potential accuracy problem with Abbott Laboratories’ rapid ID Now test, which delivers results in roughly 15 minutes. The test has been lauded by President Donald Trump and used to screen the president, his staff and visitors to the White House.The FDA alert followed a preliminary report by New York University that found Abbott’s test missed between a third to one-half of infections caught by a rival test in patients screened for the virus.Abbott rejected the findings, saying the researchers did not follow the instructions for using its test. The company pointed to alternate patient studies, including its own, that have found the test successfully detects between 91% and 95% or more of virus cases when compared to other tests.But similar problems with ID NOW’s accuracy have been flagged in preliminary reports by researchers at Stanford University, Loyola University and the Cleveland Clinic.For now, the FDA is requiring Abbott to conduct follow-up studies in several different patient groups.The FDA’s emergency standards “are still high but there is a significant difference in the body of work that what would go into a submission under the normal process,” said Abbott vice president John Hackett. “Our normal process takes years to bring these out.”Requiring bigger studies of all coronavirus tests could provide valuable information, but it could also strain the FDA’s already stretched staff and resources, said Dr. Daniel Schultz, former director of the FDA’s medical device center.Dr. Colin West of the Mayo Clinic worries doctors and patients have put too much confidence in the current crop of tests, when an unknown number of patients with COVID-19 are likely receiving false negative results.Even a modest error rate can have grave consequences during an outbreak like COVID-19. West gives the example of a test that is 95% accurate at detecting the virus and is used on 1 million people. That would still result in 50,000 people being incorrectly told that they don’t have the virus.“The negative test does not mean that I’m off the hook,” West said. “We just need to maintain that level of vigilance until we have a better sense of how good these tests really can be.”___Follow Matthew Perrone on Twitter: @AP_FDAwriter.___Follow AP pandemic coverage at http://apnews.com/VirusOutbreak and https://apnews.com/UnderstandingtheOutbreak.___The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institute’s Department of Science Education.

If US President Donald Trump considers himself "pro-life," he should reconsider his decision to end a program that allows the children of undocumented immigrants to remain in the United States, Pope Francis said."The President of the United States presents himself as pro-life and if he is a good pro-lifer, he understands that family is the cradle of life and its unity must be protected," Francis said.The Pope's comments came during a news conference aboard the papal plane, as he returned to the Vatican after a five-day trip to Colombia. In the wide-ranging Q&A with reporters, the Pope also said history will harshly judge deniers of climate change.The Pope acknowledged that he was not familiar with the specifics of DACA. "I think this law comes not from parliament but from the executive," the Pope said. "If that is so, I am hopeful that it will be re-thought."Trump and the Pope have tussled over immigration before, with the Pope saying last year that anyone who thinks only of building walls instead of bridges is "not Christian."Trump fired back, saying that no religious leader should question another man's faith.The US Catholic bishops have also battled a former Trump administration official on DACA in recent days.Steve Bannon, who until recently was Trump's chief strategist, accused the bishops of having an ulterior motive in advocating for families affected by the decision to revoke DACA. They have called the decision "heartless" and "reprehensible."Bannon said the bishops "need illegal aliens to fill the churches," a charge the bishops called "preposterous" and "insulting."   1621

In a scene that could be straight out of a children's book, around a ton of liquid chocolate flowed out of a factory and caked a street in a west German town on Monday.Firefighters said a storage tank overflowed at DreiMeister's chocolate factory in West?nnen, a suburb of the town of Werl, running out of the gates and solidifying on the chilly sidewalk."About a ton of chocolate ran out into the yard and from there onto the street, " a spokesman for the Werl fire brigade said in a statement. "A ten-square-meter choco-pancake formed," the statement added.Firefighters then worked to remove the chocolate, prying the "sweet danger with shovels and muscle power," the brigade wrote.DreiMeister's boss Markus Luckey told German newspaper Soester Anzeiger that if the spill happened closer to Christmas it "would have been a disaster."Luckey added that the factory would be back in action on Wednesday.According to the paper, around 25 firefighters were on scene to help with the clean-up.A specialist company was brought in to assist after the incident and the brigade assured locals that a chocolate-free Christmas would not be "imminent in Werl."The-CNN-Wire? & ? 2018 Cable News Network, Inc., a Time Warner Company.
