Study: Tech-based Aids Can Prevent Costly Mistakes, Delayed Diagnoses
Technology-based health care aids may help physicians and prevent costly mistakes and delayed diagnoses, according to a new review of evidence in Annals of Internal Medicine. Examples of effective aids include text message alerts sent to doctors, computer programs that use symptoms to generate lists of possible diagnoses and policies that reward doctors who make accurate diagnoses. "I think there's a general feeling that we're probably going to need multiple strategies," David Newman-Toker, MD, who studies diagnostic errors at the Johns Hopkins University School of Medicine in Baltimore and was not involved in the study, told Reuters. "Ultimately I think the biggest bang for the buck is going to come out of decision-based computer support of one kind or another, but it's not going to be easy, and it's not going to be tomorrow."

Checklist Could Help Older Americans Estimate Whether They’ll Live Another Decade
A new checklist in the Journal of the American Medical Association could estimate whether people age 50 and older will still be alive in 10 years. The checklist is designed to help health care providers and patients make better decisions. The 12 factors were determined through an analysis of data from a national study of nearly 20,000 U.S. adults older than 50. They include age, sex, weight, smoking, the presence of diabetes, lung disease, heart disease and certain physical limitations. Read more on aging.

CDC: Lethal, Drug-resistant Bacteria Spreading in U.S. Healthcare Facilities
According to the U.S. Centers for Disease Control and Prevention’s (CDC) March 2013 Vital Signs report, a family of bacteria called Carbapenem-Resistant Enterobacteriaceae (CRE) has become increasingly resistant to last-resort antibiotics during the past decade, and more hospitalized patients are contracting infections that in some cases cannot be cured. CRE are usually transmitted from person-to-person, often on the hands of health care workers. During just the first half of 2012, almost 200 hospitals and long-term acute care facilities treated at least one patient infected with these bacteria. 

Currently, almost all CRE infections occur in people receiving significant medical care in hospitals, long-term acute care facilities, or nursing homes. “CRE are nightmare bacteria. Our strongest antibiotics don’t work and patients are left with potentially untreatable infections,” said CDC Director Tom Frieden, MD, MPH.

Last year, CDC published a CRE prevention toolkit with recommendations for hospitals, long-term acute care facilities, nursing homes and health departments. Key recommendations include:

  • Enforcing use of infection control precautions (standard and contact precautions)
  • Grouping patients with CRE together
  • Dedicating staff, rooms and equipment to the care of patients with CRE, whenever possible
  • Having facilities alert each other when patients with CRE transfer back and forth
  • Asking patients whether they have recently received care somewhere else (including another country)
  • Using antibiotics wisely

In addition, CDC recommends screening patients in certain scenarios to determine whether they are carrying CRE. Because of the way CRE can be carried by patients from one health care setting to another, facilities are encouraged to work together regionally to implement CRE prevention programs. In some parts of the world, CRE appear to be more common, and evidence shows they can be controlled. Read more on bacteria.
