New AHRQ Study Finds Failure to Order Needed Tests a Leading Cause of Diagnostic Errors
Posted On: Wednesday, January 20, 2010 - 10:17 by Beverly Murphy

AHRQ researchers found that failure to order tests, report results to patients, or follow up with abnormal test findings are leading types of diagnostic errors. Results were based on a survey issued to nearly 300 primary care and specialist physicians who reported 583 cases of diagnosis error, the largest-ever study of diagnostic errors in medicine. Researchers also found that tests were overlooked because clinicians often failed to consider the diagnosis, leading to delays in ordering the tests or making the correct diagnosis. The most common missed or delayed diagnoses include pulmonary embolism, drug reactions or overdose, lung cancer, colorectal cancer, acute coronary syndrome, including heart attack, breast cancer and stroke.

The study, led by Gordon Schiff, M.D.,... MORE

JAMA focuses on fallout over Breast Cancer Screen Recommendations
Posted On: Wednesday, January 13, 2010 - 08:48 by Beverly Murphy

Several commentaries in this week's JAMA (january 13, 2010) focus on the controversial 2009 U.S. Preventive Services Task Force recommendations on breast cancer screening. In one, a former member of the task force reminds readers that the organization does not represent the government. He faults the recommendation's "poor wording" as one cause of the controversy and observes that it was "unwise" for the task force not to plan for the inevitable political fallout. In another brief essay, two experts in health outcomes research examine the real harms of overdiagnosis and decry the politicization of healthcare. "Promoting screening irrespective of the evidence may garner votes," they write, "but will not create healthier voters." There are... MORE

Free tool helps calculate return on investment from better asthma care

Employers are seeking solutions that can help reduce their health care costs without sacrificing the health care services provided to their employees or harming worker productivity. A new online, evidence-based tool, the Asthma Return-on-Investment Calculator developed by the Agency for Healthcare Research and Quality (AHRQ), can help employers decide whether it is cost-effective to establish an asthma care management program for employees and their families. According to AHRQ's 2008 National Healthcare Quality Report, the annual cost of treating asthma is nearly $20 billion, which includes nearly $15 billion in direct medical costs and another $5 billion in costs due...

JAMA. 2010;303(1):47-53.

This meta-analysis looks at six large trials, three of Paxil and three of imipramine, and shows that the effectiveness of the drugs varies according to the level of severity of depression. While the drugs are effective for severe depression, they offer little to no benefit over placebo for mild to moderate depression.
