1. AHRQ Study Finds Benefits and Risks in Two Types of Bariatric Surgery

An AHRQ-funded study published online October 29 in the journal JAMA Surgery revealed that two techniques for performing bariatric surgery had differing benefits and risks. According to the study and abstract, which compared gastric banding and bypass, bypass resulted in much greater weight loss and fewer reoperations but was linked to more risk of complications than was banding. A team of researchers at Group Health Research Institute in Seattle studied nearly 7,500 patients from 10 U.S. health care systems who had laparoscopic bariatric surgery between 2005 and 2009 and were followed through 2010. The authors suggested that patients need to have informed discussions with their doctors about which type of surgery suits them best, based on what matters most to them as individuals. The study is titled, "Comparative Effectiveness of Laparoscopic Adjustable Gastric Banding versus Laparoscopic Gastric Bypass."

2. AHRQ 2014 Nursing Home Comparative Database Report Available

Results from AHRQ’s Nursing Home Survey on Patient Safety Culture: 2014 Comparative Database Report are available for nursing homes that administered the survey to compare their patient safety culture with that of other participating U.S. nursing homes. Results from 263 U.S. nursing homes and 18,968 staff are reported. The report also presents results by various nursing home characteristics (size and ownership) and respondent characteristics (job titles, work areas, direct patient contact, shift worked and tenure in nursing home). The report presents statistics, including averages, standard deviations, minimum and maximum scores and percentiles, on the patient safety culture composites and items from the survey. For more information, contact program representatives via email or phone, 1-888-324-9790.

3. Several Imaging Options Effective for Detecting Liver Cancer

A new research review from AHRQ found that several imaging modalities for diagnosing and staging hepatocellular carcinoma, or liver cancer – the fifth most common cancer and the third most common cause of cancer-related deaths worldwide – appear to be reasonable options for the detection of liver cancer, the evaluation of focal liver lesions (tumors) or cancer staging. However, test performance (sensitivity, specificity and likelihood ratios) is lacking for small or well-differentiated hepatocellular carcinoma. For the few studies assessing diagnostic accuracy in surveillance settings, only two directly compared imaging modalities. More research is needed to understand the effects of test performance differences on clinical decision-making and clinical outcomes, according to the findings in the review, "Imaging Tests for the Diagnosis and Staging of Hepatocellular Carcinoma."

4. Register Now: Seventh Annual Dissemination and Implementation Conference December 8 and 9

Register now for the Seventh Annual Conference on the Science of Dissemination and Implementation, scheduled for December 8 and 9 in Bethesda, Maryland. The transformation of health care and public health toward a system that optimizes individual and population health is well underway, with significant expenditures at risk. As policymakers, employers, providers and patients respond to new demands to show that health care delivery and public health systems can reliably deliver evidence-based and patient-centered services, many are eager to learn what works, for whom, in what contexts and at what cost. The keynote speaker is Peter Pronovost, M.D., senior vice president for patient safety and quality, Johns Hopkins Medicine, Baltimore, Maryland. The online agenda provides a complete listing of speakers and sessions. The conference is co-hosted by the National Institutes of Health and AcademyHealth and co-sponsored by AHRQ, the Patient-Centered Outcomes Research Institute, the Robert Wood Johnson Foundation and the U.S. Department of Veterans Affairs. The deadline for online registration is December 1.

5. Draft Electronic Quality Measures Available for Public Comment on USHIK Web site

A new set of draft electronic clinical quality measures (eCQMs) have been posted for public comment on AHRQ’s United States Health Information Knowledgebase (USHIK) Web site. To access and comment on a draft measure, select the draft measures tab in USHIK and select the individual measure to view and provide comments. To submit feedback, select "provide feedback" on the individual measure’s page and fill out the form. Users can also submit feedback directly at the Web site the Office of the National Coordinator uses to track issues or bugs associated with the eCQMs. The new draft eCQMs that have been posted for comment are:

  • HIV Screening.
  • HIV Screening for Patients with Sexually Transmitted Infection (STI).
  • Oral Health Sealant for Children between 6–9 years.
  • Oral Health Care Continuity for Children between 2–20 years.

USHIK is an online, publicly accessible registry and repository of health-care-related metadata, specifications and standards. AHRQ funds and directs it with management support and engagement from numerous public and private partners.
