Outpatient Diagnostic Errors Affect 1 in 20 Adults

Outpatient Diagnostic Errors Affect 1 in 20 Adults

A new study co-funded by AHRQ found that diagnostic errors—missed opportunities to make a timely or correct diagnosis based on available evidence—occur in about 5 percent of U.S. adults and that about half of those errors could severely harm patients. The study, “The frequency of diagnostic errors in outpatient care: estimations from three large observational studies involving U.S. adult populations,” was published in the April 21 issue of BMJ Quality & Safety.

The study used data from three previous studies of errors in general primary care diagnosis, colorectal cancer diagnosis and lung cancer diagnosis. In all three studies, diagnostic errors were confirmed through rigorous chart review. Diagnostic errors can harm patients by delaying their treatment. For example, a delayed or incorrect cancer diagnosis could make the disease harder to treat or more deadly. The study is significant because it is based on a large sample size and is the most robust estimate thus far to address the frequency of diagnostic error in routine outpatient care.

The nation’s food safety grades are out and the results are mixed. CDC’s annual report card shows that foodborne infections continue to be an important public health problem in the United States.

The rate of salmonella infections decreased by about nine percent in 2013 compared with the previous three years, bringing it to the rate last observed in the 2006-2008 baseline period. But campylobacter infections, often linked to dairy products and chicken, have risen 13 percent since 2006-2008. Vibrio infections, often linked to eating raw shellfish, were at the highest level observed since active tracking began in 1996; however, rates of infections caused by Vibrio vulnificus, the most severe species, have remained steady. Rates of the other foodborne infections tracked have not changed since the period between 2006 and2008.

“CDC data are essential to gauge how we’re doing in our fight against foodborne illness,” said Robert Tauxe, M.D., M.P.H, deputy director of CDC’s Division of Foodborne, Waterborne and Environmental Diseases. “This year’s data show some recent progress in reducing salmonella rates, and also highlight that our work to reduce the burden of foodborne illness is far from over. To keep salmonella on the decline, we need to work with the food industry and our federal, state and local partners to implement strong actions to control known risks and to detect foodborne germs lurking in unsuspected foods.”

Evidence-based interventions at the local and national levels provide promising strategies for reducing racial and ethnic health disparities related to HIV infection rates, immunization coverage, motor vehicle injuries and deaths, and smoking, according to a new report by the CDC’s Office of Minority Health and Health Equity.

The report,published today as an MMWR Supplement, describes CDC-led programs addressing some of the health disparities previously highlighted in the CDC Health Disparities and Inequalities Reports, CHDIR, 2011 and 2013. The CHDIR reports highlight differences in mortality and disease risk for multiple conditions related to behaviors, access to health care, and social determinants of health – the conditions in which people are born, grow, live, age, and work.

“Reducing and eliminating health disparities is central to achieving the highest level of health for all people,” said CDC Director Tom Frieden, M.D., M.P.H. “We can close the gap when it comes to health disparities if we monitor the problem effectively and ensure that there is equal access to all proven interventions.”

Concerns Regarding a New Culture Method for Borrelia burgdorferi Not Approved for the Diagnosis of Lyme Disease

Concerns Regarding a New Culture Method for Borrelia burgdorferi Not Approved for the Diagnosis of Lyme Disease

Some tests for Lyme disease are not adequately validated and can be misleading to patients and health care providers. Recently, CDC has received inquiries regarding a test that uses a novel culture method to identify Borrelia burgdorferi, the spirochete that causes Lyme disease. Published methods and results for this test were reviewed by CDC. The review raised serious concerns about false-positive results caused by laboratory contamination and the potential for misdiagnosis and improper treatment of patients. This situation highlights the importance of FDA clearance/approval of diagnostic tests, which provides assurance that the test itself has adequate analytical and clinical validation and is safe and effective. CDC recommends that laboratory tests cleared by FDA be used to aid in the routine diagnosis of Lyme disease.

The partnership of state public health and community organizations can play an Progress in preventing foodborne illnesses has been limited. Salmonella infections decreased slightly in 2013 compared with the preceding 3 years, and are back to levels seen in 2006–2008. The frequency of most other infections tracked in Foodborne Diseases Active Surveillance Network (FoodNet) has not changed much at all; however, Vibrio infections increased in 2013. These findings highlight the need to continue to identify and address food safety gaps that can be targeted for action.Foodborne diseases continue to be an important public health problem in the United States. Progress in preventing these infections has been limited in recent years, as evidenced by a modest decrease in the incidence of Salmonella and an increase in incidence of Vibrio. FoodNet, a foodborne disease surveillance component of CDC's Emerging Infections Program, conducts surveillance in 10 U.S. sites for all laboratory-confirmed infections caused by selected pathogens transmitted commonly through food to help assess whether efforts to decrease illnesses are succeeding. This report describes 2013 surveillance data and trends since 2006; the information contributes to our understanding of the human health impact of foodborne diseases.

Blood Lead Levels Among Children Aged 1–5 Years — Zamfara State, Nigeria, June–July 2012

Blood Lead Levels Among Children Aged 1–5 Years — Zamfara State, Nigeria, June–July 2012

Much has been done to address the problems of lead exposure in Zamfara, Nigeria, since the lead poisoning crisis of 2010. New and safer processing techniques that control dust and residual ore wastes, a better understanding of potential exposure to lead contaminated foodstuffs, continued blood lead surveillance, chelation therapy when warranted and environmental cleanup of hazardous sites remain critical. Since 2010, Nigerian government officials and the international community have responded to childhood lead poisoning caused by the processing of lead-containing gold ore in Zamfara State, Nigeria. Widespread education, surveys of high-risk villages, testing and surveillance of blood lead levels (BLLs), medical treatment, and environmental clean-up have all been implemented. To evaluate the current prevalence of lead poisoning and dangerous work practices, a population-based assessment of children’s blood lead levels and ore processing techniques was conducted during June–July 2012. Unlike earlier studies, this assessment found few children in need of medical treatment, lower average BLLs, and less exposure of children to dangerous work practices. Although work remains, when these strategies are successfully implemented, a sustained reduction of blood lead levels in children is possible.

Workers, employers, and medical providers should recognize that employees can be exposed to Valley Fever even if they are not directly engaged in soil disruptive work. In 2012, more than 4,000 Californians were diagnosed with Valley Fever, a potentially serious disease caused by inhaling fungal spores common in Central and Southern California. Occupationally acquired Valley Fever most often occurs in people whose work involves digging or working in soil, such as construction workers, military personnel, or archaeologists. However, this study highlights Valley Fever in a group of workers whose occupations do not typically put them at risk of Valley Fever exposure. —The study reports on several members of the cast and crew of a popular TV series who became ill shortly after filming outdoor scenes in Ventura County. Workers, employers, and medical providers should be aware that employees working outdoors in Coccidioides (a fungus that lives in soils)prevalent areas might be exposed to Valley Fever from recent soil disturbances or windy conditions, even if they are not working in the soil.
