Alexander, G.C., and Lambert, B.L. (2012). "Is treatment heterogeneity an Achilles' heel for comparative effectiveness research?" (AHRQ grant HS18960). Pharmacotherapy 32(7), pp. 583-585.

Criticism of comparative effectiveness research highlights individual differences in treatment response (treatment heterogeneity) and warns against the perils of overreliance on "average effects." This editorial highlights misuse of the concept of treatment heterogeneity by those seeking to diminish any leverage that comparative effectiveness research may be able to achieve in improving health care value.

Baiocchi, M., Small, D.S., Yang, L., and others (2012, June). "Near/far matching: A study design approach to instrumental variables." (AHRQ grant HS18403). Health Services and Outcomes Research Methodology.

Near/far matching is capable of estimating causal effects when the outcome is not continuous and also when unmeasured covariates produce selection bias. The authors illustrate near/far matching by using Medicare data to compare the effectiveness of carotid arterial stents with cerebral protection versus carotid endarterectomy for the treatment of carotid stenosis.

Bright, T.J., Wong, A., Dhurjati, R., and others (2012). "Effect of clinical decision-support systems. A systematic review." (AHRQ Contract No. 290-07-10066). Annals of Internal Medicine 157, pp. 29-43.

This systematic review adds to the literature by summarizing trials of clinical decision support systems (CDSSs) implemented in a clinical setting to aid decisionmaking at the point of care or for a specific care situation. From their review of 148 randomized, controlled trials, the authors concluded that both commercially and locally developed CDSSs are effective at improving health care process measures across diverse settings. However, evidence for clinical, economic, workload, and efficiency outcomes remains sparse.

The researchers elucidate the epidemiology and perioperative impact of metabolic syndrome (MetS) in patients undergoing primary posterior lumbar spine fusion. Using the National Inpatient Sample, they found that patients with MetS had significantly longer length of stay, higher rates of nonroutine discharges, and increased rates of major life-threatening complications than patients without metabolic syndrome.

Memtsoudis, S.G., Sun, X., Chiu, Y-L., and others (2012, July). "Utilization of critical care services among patients undergoing total hip and knee arthroplasty." (AHRQ grant HS00514). Anesthesiology 117(1), pp. 107-116.

The authors sought to identify the incidence and risk factors for the use of critical care services (CCS) among patients undergoing total hip and knee arthroplasty and to compare the characteristics and outcomes of patients who require CCS to those who do not. They found that 3 percent of 528,495 patients undergoing this procedure required CCS. On average, CCS patients were older and had a higher comorbidity burden than those not requiring CCS.

M'ikanatha, N.M., Dettinger, L.A., Perry, A., and others (2012, March). "Culturing stool specimens for Campylobacter spp., Pennsylvania, USA." (AHRQ grant HS10399). Emerging Infectious Diseases 18(3), pp. 484-487.

The researchers surveyed 176 clinical laboratories in Pennsylvania about stool specimen testing practices for enteropathogens, including Campylobacter spp. Most of the labs routinely test for Campylobacter spp., but in 17 labs, a stool antigen test is the sole method for diagnosis. The authors recommend that laboratory practice guidelines for Campylobacter spp. testing be developed.

Nichols, G.A., Desai, J., Lfata, J.E., Lawrence, J.M., and others (2012). "Construction of a multisite datalink using electronic health records for the identification, surveillance, prevention, and management of diabetes mellitus: The SUPREME-DM Project."

The objective of this study was to identify the number of people with diabetes from a diabetes DataLink developed as part of the SUPREME_DM (Surveillance, PREvention, and ManagEment of Diabetes Mellitus) project, a consortium of 11 integrated health systems that use comprehensive electronic health record data for research. The study identified 1,085,947 members of those systems that met one or more criteria for diabetes.

Norris, S.L., Burda, B.U., Holmer, H.K., and others (2012). "Author's specialty and conflicts of interest contribute to conflicting guidelines for screening mammography." (AHRQ grant HS18500). Journal of Clinical Epidemiology 65, pp. 725-733.

The goal of this study was to examine the relationship between financial, intellectual, and professional conflicts of interest, and the recommendations in guidelines for or against routine screening mammography for asymptomatic, average-risk women aged 40–49 years. The specific objectives were to examine the relationship between the guideline recommendations and (1) the specialty of physician guideline authors, (2) financial disclosures of physician authors, and (3) the focus of the lead guideline author's academic interests inferred from his or her publications.

Odukoya, O.K., and Chui, M.A. (2012, Spring). "Commentary on the Federal Government's role in influencing e-prescribing use and research." Perspectives in Health Information Management at http://www.ncbi.nlm.nih.gov/pubmed/22737095

The authors discuss the Federal Government's role influencing e-prescribing use and research. Financial incentive and penalties have encouraged many organizations to rapidly adopt e-prescribing systems. However, rapid implementation has uncovered long-term costs and unintended patient safety hazards. This has led to a shift in focus from e-prescribing usefulness to an emphasis on safety concerns and expanded use.

Quinn, M.A., Kats, A.M., Kleinman, K., and others (2012, August 13/27). "The relationship between electronic health records and malpractice claims." (AHRQ grant HS15397). Archives of Internal Medicine 172(15), pp. 1187-1189.

Given the potential of electronic health records (EHRs) to reduce adverse events and health care costs, the question of whether EHRs reduce the risk of malpractice lawsuits is a logical one. A survey of 189 Massachusetts physicians from different specialties has found that the rate of malpractice claims when EHRs were used was about one-sixth the rate when EHRs were not used. Unmeasured factors may, in part, account for the apparent sixfold reduction in malpractice claims.
