DENVER, Colorado — A new study from the University of Colorado Anschutz Medical Campus highlights a startling aspect of the United States' opioid crisis: Many emergency room doctors don't realize just how often they're prescribing the addictive pain meds.CU researchers, along with researchers at the University of Massachusetts Medical School, conducted a year-long study examining the prescription-writing behavior of more than 100 doctors at four different hospital emergency departments.The researchers first surveyed the doctors, asking how often they prescribed opioids compared to their peers, and found that 65 percent of the doctors actually wrote more opioid prescriptions than they thought they did.Out of a total of 75,203 prescriptions written over the course of the year, 15,124 of them — or slightly more than 20 percent — were for opioids.After researchers showed the doctors the actual data, the doctors started writing fewer opioid prescriptions."Everyone showed an overall decrease in prescribing opioids," said study author Sean Michael, an assistant professor of emergency medicine at the University of Colorado School of Medicine. "After seeing their real data, the people with inaccurate self-perceptions, on average, had 2.1 fewer opioid prescriptions per 100 patients six months later and 2.2 percent fewer prescriptions per 100 patients at 12 months."The study only highlights a small piece of the opioid prescription problem, the authors state, since emergency room doctors hand out just 5 to 10 percent of all opioid prescriptions."Despite making progress on the opioid epidemic, we can't assume providers are behaving optimally and have all the information they need to do what we are asking of them," Michael said. "Most believe they are doing the right thing, but we need to directly address this thinking to be sure they are not part of the problem."The study is published in the journal Academic Emergency Medicine. 1961

DEL MAR (KGTV) — For the first time, researchers set up receivers along San Diego coast with the ability to record when sharks are near. California State University Long Beach spent Wednesday working with Del Mar lifeguards as they dropped three receivers along the coast and tried tagging sharks nearby. Unfortunately, no sharks were tagged.Chris Lowe, with Shark Lab, tells 10News, “we just got money from the state to expand it throughout all of California.” They have receivers from Avila to the Mexico border but none located between Oceanside and La Jolla."This is a big gap for us,” Lowe says.Each receiver collects data from any tagged shark within 500 yards of the device. The receiver logs the time, date and is able to identify the exact shark based on the scanned tag. For a decade, CSU Long Beach has been studying the patterns of sharks and working to collect enough data to eventually predict where sharks will be at certain times of the year. 967

Defense Secretary James Mattis is expected to sign deployment orders as soon as Thursday that could send 800 or more troops to the border with Mexico to help border patrol authorities stop a caravan of migrants from Central America moving through Mexico to enter the US, according to three administration officials.The officials tell CNN final details are being worked out including where the troops will come from and their specific tasks.The troops will not engage in lethal operations to stop the migrants. Instead they are expected to provide fencing, wall materials and other technical support at several key points along the border where it is believed the migrants may try to cross.The troops will also provide tents and medical care for border authorities in those areas. The troops retain the right of self-defense, but border patrol officers will still be the ones physically stopping illegal migration, the officials said. 941

DEL MAR, Calif. (KGTV) -- A plan meant to increase safety along Del Mar's famous coastal bluffs is being met with deep resistance by residents, surfers and walkers.North County Transit District says it has obtained grants to fund building a fence to protect the train tracks on the bluffs. It would aim to end 100 years of people illegally crossing the tracks to get down to the beach or take in the views.The district says it would help prevent erosion and increase safety - six people have been hit by trains in Del Mar in the last two years. RELATED: Del Mar bluff collapses for second time since AugustThe Del Mar City Council will discuss the proposal at its meeting Monday. "They put a fence up there it's not going to stop me," said Chris Gable, a longtime Del Mar surfer. "I understand it's a safety hazard since they're upping the frequency of the trains, but I don't think it's going to go over well."Del Mar Mayor Dwight Worden said the fencing is an overreaction. He said a better plan is to increase education, signage, citizen enforcement, and to build protected legal crossings. Residents and surfers say people would cut through or climb the fence, and that could trap them if a train comes - and that the fence could cut off an escape route in the event of a wildfire. They also cringe at the aesthetics.RELATED: Researchers tracking crumbling Del Mar bluffs"The idea that we have no access to the beach and have a fence in front of us is not a good idea," said Karla Leopold, whose home overlooks the ocean and bluffs. Del Mar is also discussing placing four legal crossings at various parts of the city, but that would require a 0,000 feasibility study. The earliest that could begin is next summer.  1780

DEL MAR, Calif. (KGTV) – The Bing Crosby Season at the Del Mar Racetrack kicks off Saturday with new rules to keep everyone involved healthy and safe.Del Mar Thoroughbred Club Media Director Mac McBride told ABC 10News, "We normally have one large jockey's room. What we've done now is made three jockey’s rooms to thin out the ranks so they're not sitting on top of each other like they do normally.”Due to the ongoing COVID-19 pandemic, this racing season will be noticeably different than years past. This season, jockeys will also wear masks on and off the horses, test daily for the coronavirus, and if anyone receives a positive result, they'll be required to quarantine for at least 10 days."When we put that into place in the summer after our first hiccup, it worked out well. We had no further incidents with our riders,” McBride said.McBride added that even though the club took a big hit with empty stands this summer, folks were still tuning in and bets were still flying high."We thought we might do well, but we had no idea how we were going do that well, and we did. The jump from million to million average a day staggered us, it was amazing,” said McBride.Thanks to betting profits, the racetrack was able to maintain their four-legged showstoppers, which is their top priority, among keeping everyone safe."Even if we raced and lost money, it still would've been a good thing because horses in the end would be taken care of, and that's the focus right now. Keep horses well fed and safe,” McBride told ABC 10News.Organizers will also be keeping an eye out where San Diego County stands in the state's COVID-19 tier system. If the county were to fall from the red tier into the yellow tier, outdoor sporting events like theirs could allow them to fill seats."Obviously, we wouldn't look for 40,000 people, but if we had 4,000 or something like that sure, we could bring them in, and space them out. We'd love to bring them back,” said McBride.Another big event in the future is the world-famous Breeder's Cup. It's slated to take place in Del Mar next November and organizers said they're preparing now, COVID-19 or not. 2154
