The association between contrast dose and renal complications post PCI across the continuum of procedural estimated risk.
PLoS ONE
PUBLISHED: 01-01-2014
Show Abstract
Hide Abstract
Prior studies have proposed to restrict the contrast volume (CV) to <3x calculated creatinine clearance (CCC), to prevent contrast induced nephropathy (CIN) post percutaneous coronary interventions (PCI). The predictive value of this algorithm for CIN and therefore the benefit of this approach in high risk patients has been questioned. The aim of our study was to assess the association between contrast dose and the occurrence of CIN in patients at varying predicted risks of CIN and baseline CCC following contemporary PCI.

Orthographic learning and self-teaching in a bilingual and biliterate context.
J Exp Child Psychol
PUBLISHED: 08-13-2013
Show Abstract
Hide Abstract
The aim of this study was to examine self-teaching in the context of English as a foreign language literacy acquisition. Three groups comprising 88 sixth-grade children participated. The first group consisted of Russian-Hebrew-speaking bilinguals who had acquired basic reading skills in Russian as their first language (L1) and literacy and who were literate in Hebrew as a second language. The second group consisted of Russian-Hebrew-speaking bilinguals who had not learned to read in their native Russian but had acquired Hebrew as their first literate language. The third group consisted of Hebrew-speaking monolingual children who were literate in Hebrew. This design facilitated examining the effect of biliteracy and bilingualism on basic English reading skills. We hypothesized that due to the proximity between the Russian and English orthographies as opposed to the Hebrew-English "distance," the Russian-Hebrew-speaking biliterate group who acquired basic reading and spelling skills in L1 Russian would have superior self-teaching in English as opposed to the two other groups. The standard two-session self-teaching paradigm was employed with naming (speed and accuracy) and orthographic choice as posttest measures of orthographic learning. Results showed that after 4 years of English instruction, all three groups showed evidence of self-teaching on naming speed and orthographic recognition. The Russian-Hebrew-speaking biliterate group, moreover, showed a partial advantage over the comparison groups for initial decoding of target pseudowords and clear-cut superiority for measures of later orthographic learning, thereby showing self-teaching while supporting the script dependence hypothesis.

Outcome data regarding postoperative acute coronary syndrome treated with percutaneous coronary intervention (PCI) are limited. The objective of this study was to determine clinical outcomes of patients undergoing PCI within 7 days after a surgical procedure. We assessed outcomes of 517 patients who underwent PCI within 7 days after a surgery across 44 hospitals from January 2010 to December 2011 from the Blue Cross Blue Shield of Michigan Cardiovascular Consortium registry. Patients with postoperative PCI were compared with all other patients with PCI using propensity-matched analysis. Of the 65,175 patients who underwent PCI within the study period, 517 patients had undergone surgery within the previous 7 days. In unadjusted analysis, patients with postsurgical PCI had higher in-hospital mortality (6.96% vs 1.33%), stroke (0.96% vs 0.26%), bleeding events (6.96% vs 2.6%), heart failure (6.96% vs 2.36%), and cardiogenic shock (7.16% vs 1.95%). After propensity matching, mortality remained higher in postsurgical patients (6.5% vs 3.96%, odds ratio 1.7 [1.1 to 2.6], p = 0.02). The odds of mortality were especially high among patients who would otherwise be considered low risk (<1% of predicted mortality in a nonsurgical setting) in whom a recent surgery was strongly associated with death (odds ratio 5.7, p = 0.02). In conclusion, PCI performed within 7 days after a surgical procedure is associated with an increased risk of early mortality. Although some of this increased risk is related to an adverse clinical profile, higher mortality is also observed in patients otherwise considered low risk for PCI.

Early use of ? blockers (BBs) in acute myocardial infarction remains controversial, with some studies demonstrating benefit and others harm. The aim of this study was to assess the association between pre-percutaneous coronary intervention (PCI) BB use and in-hospital outcomes in patients who underwent primary PCI for ST-segment elevation myocardial infarction between 2007 and 2009 at institutions participating in the Blue Cross Blue Shield of Michigan Cardiovascular Consortium (BMC-2). Inverse propensity score weighting was used to account for the nonrandomized use of pre-PCI BBs. The cohort comprised 7,667 patients, with 4,769 (62%) receiving pre-PCI BBs. These patients were older, with higher rates of diabetes mellitus, hypertension, and previous myocardial infarction, PCI, or coronary artery bypass grafting. In adjusted models, pre-PCI BB use was associated with lower rates of intraprocedural ventricular tachycardia or ventricular fibrillation (odds ratio [OR] 0.58, p <0.01) and lower in-hospital mortality (OR 0.65, p = 0.022), with increases in rates of emergent coronary artery bypass grafting (OR 1.56, p <0.01) and repeat PCI (OR 1.93, p <0.01). There were no significant increases in rates of cardiogenic shock and congestive heart failure. In conclusion, pre-PCI BB use in this population was associated with decreased arrhythmia and mortality, without increasing rates of cardiogenic shock and heart failure but with higher rates of repeat PCI and emergent coronary artery bypass grafting, suggesting that there may yet remain a role for early BB use in pre-PCI patients with ST-segment elevation myocardial infarctions.

How a regional collaborative of hospitals and physicians in Michigan cut costs and improved the quality of care.

Show Abstract
Hide Abstract
There is evidence that collaborations between hospitals and physicians in particular regions of the country have led to improvements in the quality of care. Even so, there have not been many of these collaborations. We review one, the Michigan regional collaborative improvement program, which was paid for by a large private insurer, has yielded improvements for a range of clinical conditions, and has reduced costs in several important areas. In general and vascular surgery alone, complications from surgery dropped almost 2.6 percent among participating Michigan hospitals-a change that translates into 2,500 fewer Michigan patients with surgical complications each year. Estimated annual savings from this one collaborative are approximately $20 million, far exceeding the cost of administering the program. Regional collaborative improvement programs should become increasingly attractive to hospitals and physicians, as well as to national policy makers, as they seek to improve health care quality and reduce costs.

In patients with acute ST-elevation myocardial infarction (STEMI) who are undergoing percutaneous coronary intervention, current guidelines for reperfusion therapy recommend a door-to-balloon (DTB) time of less than 90 minutes. Considerable effort has focused on reducing DTB time with the assumption that a reduction in DTB time translates into a significant reduction in mortality; however, the clinical impact of this effort has not been evaluated. Therefore, our objective was to determine whether a decline in DTB time in patients with STEMI was associated with an improvement in clinical outcomes.

Hide Abstract
Contrast-induced acute kidney injury (CI-AKI) is a common complication of percutaneous coronary intervention (PCI). Current guidelines support the use of iodixanol (Visipaque®, GE Healthcare, Princeton, New Jersey) in patients at high risk for CI-AKI. Recent trials and meta-analyses have shown no difference in CI-AKI when iodixanol is compared to low-osmolar contrast media (LOCM). We evaluated the incidence of CI-AKI, in-hospital dialysis and in-hospital death in 58,957 patients who underwent PCI in 2007 and 2008 in a large regional consortium of 31 hospitals and who were treated with iodixanol (n = 17,814) or LOCM (n = 41,143). Propensity-matched analysis was performed to adjust for differences in baseline variables. Patients treated with iodixanol compared to those treated with LOCM were slightly older, had more medical comorbidities and a higher baseline creatinine (1.35 ± 1.07 mg/dL versus 1.10 ± 0.85 mg/dL; p < 0.0001). In propensity-matched, risk-adjusted models, there was no significant difference between iodixanol and LOCM in the risk of CIAKI (4.54% vs. 4.14%; p = 0.14), need for dialysis (0.37% vs. 0.43%; p = 0.35) or death (1.46% vs. 1.39%; p = 0.18). Among patients undergoing PCI, the use of iodixanol was more frequent in older patients with more comorbidities and worse baseline renal function. There was no difference in the adjusted risk of CI-AKI among patients treated with iodixanol compared with those treated with LOCM.

Subtypes of reading disability in a shallow orthography: a double dissociation between accuracy-disabled and rate-disabled readers of Hebrew.

Show Abstract
Hide Abstract
Whereas most English language sub-typing schemes for dyslexia (e.g., Castles & Coltheart, 1993) have focused on reading accuracy for words varying in regularity, such an approach may have limited utility for reading disability sub-typing beyond English in which fluency rather than accuracy is the key discriminator of developmental and individual differences in reading ability. The present study investigated the viability of an accuracy/fluency-based typology in a regular orthography, pointed Hebrew. We sought evidence of true or "hard" accuracy/rate subtypes in the strict (double dissociation) sense of selective impairment on only one dimension in the presence of normal levels of performance on the other dimension. In a nationally representative sample of fourth graders, we were able to identify a specific accuracy-disabled sub-group as well as an equally specific rate-disabled subgroup. Validating this subdivision, we show that the nature of reading performance in these subgroups and their converging cognitive/linguistic profiles are unique and distinctive on variables other than the measures used to define them. While the rate-specific disability appeared to reflect a general deficit in speed of processing affecting reading rate, and rapid automatized naming of print-related material, the accuracy-only disability subgroup displayed selective deficits in phonological awareness and morphological knowledge. Biosocial, demographic, and instructional factors, furthermore, did not explain the sub-group differences. It appears that both these subtypes are equally prevalent each counting close to 10% of the population.

Michigans Physician Group Incentive Program offers a regional model for incremental fee for value payment reform.
Health Aff (Millwood)
Show Abstract
Hide Abstract
Blue Cross Blue Shield of Michigan partnered with providers across the state to create an innovative, "fee for value" physician incentive program that would deliver high-quality, efficient care. The Physician Group Incentive Program rewards physician organizations-formal groups of physicians and practices that can accept incentive payments on behalf of their members-based on the number of quality and utilization measures they adopt, such as generic drug dispensing rates, and on their performance on these measures across their patient populations. Physicians also receive payments for implementing a range of patient-centered medical home capabilities, such as patient registries, and they receive higher fees for office visits for incorporating these capabilities into routine practice while also improving performance. Taken together, the incentive dollars, fee increases, and care management payments amount to a potential increase in reimbursement of 40 percent or more from Blue Cross Blue Shield of Michigan for practices designated as high-performing patient-centered medical homes. At the same time, we estimate that implementing the patient-centered medical home capabilities was associated with $155 million in lower medical costs in program year 2011 for Blue Cross Blue Shield of Michigan members. We intend to devote a higher percentage of reimbursement over time to communities of caregivers that offer high-value, system-based care, and a lower percentage of reimbursement to individual physicians on a service-specific basis.

Composite Measures for Profiling Hospitals on Bariatric Surgery Performance.

Show Abstract
Hide Abstract
IMPORTANCE The optimal approach for profiling hospital performance with bariatric surgery is unclear. OBJECTIVE To develop a novel composite measure for profiling hospital performance with bariatric surgery. DESIGN, SETTING, AND PARTICIPANTS Using clinical registry data from the Michigan Bariatric Surgery Collaborative, we studied all patients undergoing bariatric surgery from January 1, 2008, through December 31, 2010. For laparoscopic gastric bypass surgery, we used empirical Bayes techniques to create a composite measure by combining several measures, including serious complications, reoperations, and readmissions; hospital and surgeon volume; and outcomes with other related procedures. Hospitals were ranked for 2008 through 2009 and placed in 1 of 3 groups: 3-star (top 20%), 2-star (middle 60%), and 1-star (bottom 20%). We assessed how well these ratings predicted outcomes in the next year (2010) compared with other widely used measures. MAIN OUTCOMES AND MEASURES Risk-adjusted serious complications. RESULTS Composite measures explained a larger proportion of hospital-level variation in serious complication rates with laparoscopic gastric bypass than other measures. For example, the composite measure explained 89% of the variation compared with only 28% for risk-adjusted complication rates alone. Composite measures also appeared better at predicting future performance compared with individual measures. When ranked on the composite measure, 1-star hospitals had 2-fold higher serious complication rates (4.6% vs 2.4%; odds ratio, 2.0; 95% CI, 1.1-3.5) compared with 3-star hospitals. Differences in serious complication rates between 1- and 3-star hospitals were much smaller when hospitals were ranked using serious complications (4.0% vs 2.7%; odds ratio, 1.6; 95% CI, 0.8-2.9) and hospital volume (3.3% vs 3.2%; odds ratio, 0.85; 95% CI, 0.4-1.7). CONCLUSIONS AND RELEVANCE Composite measures are much better at explaining hospital-level variation in serious complications and predicting future performance than other approaches. In this preliminary study, it appears that such composite measures may be better than existing alternatives for profiling hospital performance with bariatric surgery.

In some cases the language used in the PubMed abstracts makes matching that content to a JoVE video difficult. In other cases, there happens not to be any content in our video library that is relevant to the topic of a given abstract. In these cases, our algorithms are trying their best to display videos with relevant content, which can sometimes result in matched videos with only a slight relation.
