BACKGROUND: Most patients in the North American Symptomatic Carotid Endarterectomy Trial (NASCET) did not receive lipid-lowering treatment. As vascular event rates can be lowered with statins, antihypertensive agents, and newer antiplatelet agents, the authors conducted a study to determine the usage of these medications in patients following carotid endarterectomy (CE). METHODS: Claims data from Blue Cross and Blue Shield Michigan were used to study non-Medicare members who underwent CE in the years 1999 to 2001 (n = 1,049). Prescription of pharmacotherapy and sustained use (>80% use of the follow-up period) were examined in the 365-day period following index CE. RESULTS: Overall, 1,049 individuals underwent CE during the years 1999 to 2001. For the 1-year period following CE, the statin prescription rate was 70, 66, and 73% for the 3 study years. Sustained statin use was noted, on average, in 38%. The 3-year average was lower for sustained use of angiotensin-converting enzyme inhibitor (19%) and even lower for prescription antiplatelet agents (5%). CONCLUSIONS: Use of statins has increased following carotid endarterectomy (CE) compared with the North American Symptomatic Carotid Endarterectomy Trial era, but sustained treatment with statins remains at <40%. Recent studies have shown a decrease in vascular event rates with statins regardless of low-density lipoprotein level, suggesting that statin use should be routine following CE. Increased statin use as part of a multimodality intensive medical regimen following CE has the potential to improve long-term vascular event rates in this population.
BACKGROUND: Risk-adjustment models for percutaneous coronary intervention (PCI) mortality have been recently reported, but application in bedside prediction of prognosis for individual patients remains untested. METHODS AND RESULTS: Between July 1, 1997 and September 30, 1999, 10 796 consecutive procedures were performed in a consortium of 8 hospitals. Predictors of in-hospital mortality were identified by use of multivariate logistic regression analysis. The final model was validated by use of the bootstrap technique. Additional validation was performed on an independent data set of 5863 consecutive procedures performed between October 1, 1999, and August 30, 2000. An additive risk-prediction score was developed by rounding coefficients of the logistic regression model to the closest half-integer, and a visual bedside tool for the prediction of individual patient prognosis was developed. In this patient population, the in-hospital mortality rate was 1.6%. Multivariate regression analysis identified acute myocardial infarction, cardiogenic shock, history of cardiac arrest, renal insufficiency, low ejection fraction, peripheral vascular disease, lesion characteristics, female sex, and advanced age as independent predictors of death. The model had excellent discrimination (area under the receiver operating characteristic curve, 0.90) and was accurate for prediction of mortality among different subgroups. Near-perfect correlation existed between calculated scores and observed mortality, with higher scores associated with higher mortality. CONCLUSIONS: Accurate predictions of individual patient risk of mortality associated with PCI can be achieved with a simple bedside tool. These predictions could be used during discussions of prognosis before and after PCI.

A pattern of performance on the WAIS-R presumably related to temporal lobe abnormalities associated with Alzheimer's Disease was examined in patients with focal temporal lobe EEG abnormalities to determine if the profile was related to other forms of temporal lobe disease. Among 120 patients with unilateral or bilateral temporal lobe EEG abnormalities, only 4(3%) demonstrated the profile. The presence of the profile was unrelated to laterality of EEG abnormality. These findings were discussed in regard to previous studies and the utility of the so-called Fuld profile.
A study was conducted to assess the reliability and validity of the Appropriateness Evaluation Protocol (AEP), the Standardized Medreview Instrument (SMI) and the Intensity-Severity-Discharge criteria set (ISD), three utilization review instruments used to determine whether inpatient care is required. Reliability and validity were assessed for retrospective application of these instruments to charts of a sample of 119 medical cases from 21 hospitals in the state of Michigan. The reliability of each instrument was determined by having the instrument applied by two different nurse reviewers to each hospital record. Results indicated that the AEP and ISD were moderately reliable, while the SMI had low reliability. The validity of each instrument was tested by comparing the judgments of nurse reviewers using the instruments with the judgment of a panel of physicians. The AEP and ISD were found to be moderately valid and the SMI was found to have low validity. Results suggested that the SMI should not be used. The modest level of validity of the other two instruments suggests that payment should never be denied on the basis of the instrument alone. Payment should be denied only if a physician confirms the judgment based on the instrument that inpatient care was not required.
Researchers from the Michigan Health Care Education and Research Foundation, a research affiliate of Blue Cross and Blue Shield of Michigan, compared three focused utilization review (UR) strategies to determine which method most effectively and efficiently identifies nonacute inpatient hospital admissions. Intensity, Severity, Discharge-Appropriateness (ISD-A) criteria were used to identify nonacute admissions in 8,973 cases in 73 Michigan hospitals. Significant proportions of nonacute admissions were found in medical, psychiatric, and substance abuse cases; surgical admissions had the lowest rates. Strategies involving the concentration ratio were most effective at indicating potential efficiency gains. Focused UR on Diagnosis-Related Groups (DRGs) with nonacute rates greater than 15% captured 41% of admissions and accounted for 85% of nonacute admissions, 85% of nonacute days, and 80% of potential dollar savings. This suggests that UR efforts focused primarily on DRGs with high nonacute rates would significantly improve the efficiency and effectiveness of the overall UR process.
