Preventable Hospital Patient Problems Decline: U.S. Report
Preventable problems such as infections, bed sores, and medication errors fell 17 percent at U.S. hospitals from 2010 to 2013, according to a federal government report.
The report said the 1.3 million fewer problems during that time saved the lives of about 50,000 patients and about $12 billion in health care costs, the Associated Press reported.
Factors that may have contributed to the decrease include public reporting of errors and financial penalties implemented under the Affordable Care Act, according to the report.
"Today's results are welcome news for patients and their families," Health and Human Services Secretary Sylvia Burwell said in a statement. "These data represent significant progress in improving the quality of care that patients receive while spending our health care dollars more wisely."
Much more needs to be done to improve health care quality and to determine the types of patient safety measures that are most effective in hospitals, according to Dr. Peter Angood, of the American Association for Physician Leadership.
The report said these preventable problems still affect one in 10 hospital patients, said Angood, who was not involved with the federal report.
"A 10 percent significant error rate that creates harm, disability and possible death is way too high in American health care," he told the AP.
The problems examined in the report included surgical site infections, bloodstream infections, catheter-associated urinary tract infections, bed sores, and medication errors. Most of the overall decline in these problems came from a drop in medication errors and bed sores.
Obama to Focus on Ebola Vaccine Research at NIH Visit
Advances in efforts to develop a safe and effective Ebola vaccine will be highlighted by President Barack Obama during his visit Tuesday to the National Institutes of Health.
It's also expected that the president will push for Congress to approve his request for $6.2 billion to fight Ebola in other countries and to prevent its spread in the United States, the Associated Press reported.
Lawmakers should "take prompt action on this," according to White House spokesman Josh Earnest.
Last week, American researchers released a study saying an experimental Ebola vaccine seems safe and triggered immune protection in volunteers, the AP reported.
Guinea and Liberia Achieve Ebola Containment Goals: WHO
Guinea and Liberia have met the World Health Organization's Dec. 1 target for isolating 70 percent of Ebola patients and safely burying 70 percent of those who die from the disease.
However, Sierra Leone did not achieve those objectives, the WHO said Monday, the Associated Press reported.
Last week, the WHO said Guinea was the only one of the three hardest-hit West African nations on track to meet the targets, which were announced two months ago.
Since then, "tremendous progress" has been made in slowing the spread of the deadly disease, and the next 60 days will be crucial, according to U.N. Ebola chief David Nabarro, the AP reported.
The first cases of Ebola were reported in March and the outbreak was declared a public health emergency in August. More than 16,000 people have been sickened and nearly 7,000 of them have died.
Ebola cases appear to be falling or stabilizing in Liberia and Guinea in recent weeks. But there has been a spike in cases around Sierra Leone's capital and a district in the country's north, the AP reported.
WHO's failure to meet its Dec. 1 targets suggests the outbreak could widen as resources become even more stretched, according to an expert.
"We need to redouble our efforts to see what we can do to reduce the spread and catch up with the virus. Right now, it doesn't look good," Oyewale Tomori, of Redeemer's University in Nigeria, who sits on WHO's Emergency Ebola committee, told the AP.
However, other experts suggest the WHO's Dec. 1 targets weren't significant.
"You want to isolate 100 percent of patients with Ebola and have 100 percent safe burials," Sebastian Funk, director of the Centre for the Mathematical Modeling of Infectious Diseases at the London School of Hygiene and Tropical Medicine, told the AP. "Getting to 70 percent doesn't really mean a lot."
By Jan. 1, the WHO wants to isolate all Ebola patients and have safe burials for all victims.
"We hope that what we're seeing in Liberia will continue, but unfortunately what can happen with Ebola is that it can go to new countries, as it has already to Mali," Dr. David Heymann, an Ebola expert who previously worked for the WHO, told the AP.
"The most dangerous thing would be if people now think Ebola is over and become complacent," he added.
Pointing to a decline in cases, the United States recently announced it was reducing the size and number of Ebola clinics it had initially pledged to build in Liberia, the AP reported.
