Alexander, C. (2011). "Seeding trials and the subordination of science." (AHRQ grant HS18996). Archives of Internal Medicine 171(12), pp. 1107-1108.
A seeding trial is a study of an approved drug or device in which the primary objective is marketing, not scientific investigation. Such trials necessarily depend on deception, according to the author. The author comments in detail on an article analyzing a trial of the drug Neurontin, which concludes that the trial was actually a seeding trial used to promote and increase the prescribing of the drug.

Screening for prostate cancer by prostate-specific antigen (PSA) testing has been advocated as a means of reducing mortality from this disease. However, the best quality evidence currently available suggests that PSA screening for prostate cancer is either ineffective at reducing deaths due to prostate cancer, or confers a modest mortality advantage, but at the cost of an important degree of overdiagnosis and overtreatment.

Results from the placebo arm of the fracture intervention trial." (AHRQ grant HS16956). Journal of Bone and Mineral Research 26(4), pp. 683-688.
Several studies have reported a strong inverse relation between high compliance with oral bisphosphonates and fracture risk. Among women participating in the Fracture Intervention Trial who were randomized to placebo, there were no significant associations between compliance with placebo and fractures. However, high compliance with placebo was associated with total-hip bone loss and a similar trend was observed for changes in femoral neck bone mineral density.

Community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) is resistant to several commonly used antibiotics and that resistance is increasing. Analysis of a series of 9 focus groups conducted with 78 primary care clinicians found that no well-accepted diagnostic or treatment algorithms were used by physicians attending the focus groups. The clinicians in the study noted that there was considerable confusion and inconsistency in the management of skin and soft tissue infections.

Many physicians still do not routinely inquire about intimate partner violence (IPV). After receiving a seven-session modular curriculum over a 10 week period from a non-physician academic detailer, three physicians reported increased clarity with regard to the scope of their responsibility to their patients suffering from IPV. Academic detailing may improve physician attitudes and practices towards patients in violent relationships.
Fagnan, L.J., Dorr, D.A., Davis, M., and others (2011). "Turning on the care coordination switch in rural primary care. Voices from the practices—clinician champions, clinician partners, administrators, and nurse care managers." (AHRQ Contract No. 290-07-10016). Journal of Ambulatory Care Management 34(30), pp. 304-318.
Implementing care coordination to improve chronic illness care faces monumental challenges. This qualitative analysis explored convergence and divergence in perceptions among the four practice cohorts (clinician champions, clinicians, administrators, and nurse care managers) regarding implementation of nurse care management in medium to large rural primary care practices. Based on their analysis of interviews with the different cohorts, the researchers identified seven factors needed to assure the overall success of a care coordination program.

In the area of practice-based research (PBR), quality improvement, and public health, there are many situations where randomization is not possible. The researchers present a review of design features and practical considerations for PBR implementation of the stepped-wedge and wait-list design. They also discuss published examples from studies of clinic-based interventions using these designs. These features allow for the collection of control data, but also permit all participants to receive the intervention.

(AHRQ Contract No. 290-05-00361). Population Health Management 14. (E-pub ahead of print).
The authors describe a practical approach to identifying a cohort of newly diagnosed type 2 diabetes cases in an electronic health record (EHR). The EHR has advantages over administrative data and prospective clinical trials as a data source for comparative effectiveness research and population management. However, use of data from current systems mandates significant tailoring for application in research. Verifications of EHR data with external data sources is a high-yield step.

(AHRQ Contract No. 290-2007-10059). Clinical Biochemistry 44, pp. 754-757.
The authors' review summarizes the evidence regarding thiopurine methyltransferase (TPMT) testing in chronic autoimmune disease. Their review showed that sufficient pre-analytical data were available to recommend preferred specimen collection, stability, and storage conditions for determination of TPMT status. There was no clinically significant effect on TPMT activity of age, gender, various co-administered drugs, or most morbidities.
Meddings, J., and Saint, S. (2011). "Disrupting the life cycle of the urinary catheter." (AHRQ grant HS19767). Clinical Infectious Diseases 52(11), pp. 1291-1293.
Tackling unnecessary urinary catheter use is certainly the most important goal in preventing catheter-associated urinary tract infection. However, kicking the catheter habit can be difficult. The authors discuss an article by Knoll, et al. in this issue describing a 5-year hospital-wide "catheter quit program," which is similar in its successes and challenges to aspects of other habit-changing programs such as treating an addiction to tobacco.

Dr. David Meyers, director of the Agency for Healthcare Research and Quality's (AHRQ) Center for Primary Care, pays tribute to David Lanier, M.D., on the occasion of his retirement from AHRQ in December 2010. Over the past decade, Dr. Lanier provided visionary leadership as he designed, implemented, and nurtured AHRQ's primary care Practice-based Research Networks.
Murray, D.J. (2011, May). "Current trends in simulation training in anesthesia." (AHRQ grant HS18374). Minerva Anesthesiologica 77, pp. 528-533.
Simulation includes a number of devices and technologies that, when used in training, offer the potential to accelerate the acquisition of skills and expand the breadth of a trainee's clinical experiences. The purpose of this review is to highlight some of the more recent studies that have advanced simulation-based training and assessment strategies, with particular emphasis on those studies that either describe the results of a curriculum intervention or provide insight about the future uses of simulation.
Navathe, A.S., Clancy, C., and Glied, S. (2011). "Advancing research data infrastructure for patient-centered outcomes research." Journal of the American Medical Association 306(11), pp. 1254-1255. Reprints (AHRQ Publication No. 12-R013) are available from the AHRQ Publications Clearinghouse.
Much of patient-centered outcomes research relies on observational and quasi-experimental methods applied to data generated as a byproduct of providing care. While existing data sources have improved, there remain important data-related barriers to rapid, efficient research. The latest developments in information technology (virtual data access and distributed data network technologies) can help create an efficient data infrastructure supporting patient-centered care.

The researchers used descriptive statistics to report barriers and facilitators to walking and physical activity among older American Indians. Lack of willpower was the most commonly reported barrier. Health-related quality of life was inversely related to physical activity barriers, and poor mental health quality of life was more strongly associated with total barriers than poor physical health.

Prescribing is often driven by pharmaceutical marketing and by patients requesting drugs they hear advertised. To counterbalance these prescribing pressures, which include often unrealistic patient expectations, practice time constraints, and paucity of data and practical guidance, the authors (physicians, pharmacists, and educators) have identified principles for safer and more evidence-based prescribing.
