Abstract
Abstract
The VIDAS Immuno-concentration Salmonella (ICS)/VIDAS Salmonella (SLM) immunoassay method for the detection of Salmonella was compared to the Bacteriological Analytical Manual (BAM)/AOAC culture method in a collaborative study. Thirty-two laboratories participated in the evaluation. Each laboratory tested one or more of the 6 test products: milk chocolate, nonfat dry milk, dried whole egg, soy flour, ground black pepper, and ground raw turkey. The 2 methods were in agreement for 1266 of the 1440 samples. Of the 174 samples not in agreement, 69 were VIDAS ICS/SLM-positive and BAM/AOAC-negative and 105 were VIDAS ICS/SLM-negative and BAM/AOAC-positive.

Abstract
Tennessee's TennCare program, established in 1994, uses a managed care system to address the problem of escalating Medicaid costs while expanding coverage to the chronically uninsured. This paper examined TennCare based on results of survey research commissioned by the state and conducted by the authors. Findings indicated that respondents formerly on Medicaid who had previously indicated a preference for Medicaid were now much more likely to prefer TennCare and were now as satisfied with TennCare as they had been with Medicaid in 1993. TennCare has had some impact on health care behavior, with fewer recipients seeking care at a hospital and more seeking care at a doctor's office or a clinic. At this point, Tennessee's experience with TennCare seems to be successful. Tennessee has been able to fund a fairly significant increase in coverage of the uninsured population while staying within the projected cost parameters of the Medicaid system.

Abstract
Magnetic resonance imaging (MRI) and computerized tomography (CT) are promising reference methods for quantifying whole body and regional skeletal muscle mass. Earlier MRI and CT validation studies used data-acquisition techniques and data-analysis procedures now outdated, evaluated anatomic rather than adipose tissue-free skeletal muscle (ATFSM), studied only the relatively large thigh, or found unduly large estimation errors. The aim of the present study was to compare arm and leg ATFSM cross-sectional area estimates (cm2) by using standard MRI and CT acquisition and image-analysis methods with corresponding cadaver estimates. A second objective was to validate MRI and CT measurements of adipose tissue embedded within muscle (interstitial adipose tissue) and surrounding muscle (subcutaneous adipose tissue). ATFSM area (n = 119) by MRI [38.9 +/- 22.3 (SD) cm2], CT (39.7 +/- 22.8 cm2), and cadaver (39.5 +/- 23.0 cm2) were not different (P > 0.001), and both MRI and CT estimates of ATFSM were highly correlated with corresponding cadaver values [MRI: r = 0.99, SE of estimate (SEE) 3.9 cm2, P < 0.001; and CT: r = 0.99, SEE = 3.8 cm2, P < 0.001]. Similarly good results were observed between MRI- and CT-measured vs. cadaver-measured interstitial and subcutaneous adipose tissue. For MRI-ATFSM the intraobserver correlation for duplicate measurements in vivo was 0. 99 [SEE = 8.7 cm2 (2.9%), P < 0.001]. These findings strongly support the use of MRI and CT as reference methods for appendicular skeletal muscle, interstitial and subcutaneous adipose tissue measurement in vivo.

Abstract
BACKGROUND: Few investigators have examined the hemodynamic status related to circadian and sleep-related cardiovascular events in critically ill patients. OBJECTIVE: To describe the relationships among nocturnal angina, myocardial infarction, and sleep, and to describe the cardiac rhythm, heart rate, and frequency of premature supraventricular and ventricular contractions during the sleep of critical care patients with cardiovascular disease. METHODS: A descriptive survey was done on nine patients in the medical intensive care unit of a large medical center. All subjects had cardiovascular disease and were studied during one night of sleep. RESULTS: There were no incidences of chest pain during the study and no changes in baseline cardiac rhythm associated with sleep staging. There was a significant statistical difference in mean heart rate among waking, stage 1 nonrapid-eye-movement sleep, and stage 2 nonrapid-eye-movement sleep; a lower heart rate was observed in stage 2 nonrapid-eye-movement sleep. The mean heart rate decreased by 3% to 4% from the waking state to sleep. No clinical or statistically significant differences in the frequency of premature supraventricular and ventricular contractions between sleep stages or sleeping and waking were found. CONCLUSIONS: The results of this pilot investigation do not suggest that dysrhythmia occurs more frequently during certain sleep stages or during the sleep state in critical care unit patients with cardiovascular disease. The mean heart rate slowed by 3% to 4% during rapid-eye-movement and nonrapid-eye-movement sleep, but decreases in heart rate were not as great as those noted in normal, healthy subjects.

Abstract
Under Medicare, one of the federally required objectives of peer review organizations is to reduce inappropriate and unnecessary admissions. We reevaluated 32 admissions approved and 32 denied by the Arizona peer review organization, Health Services Advisory Group (HSAG), in a "blind" manner to determine whether practicing physicians in the community agree with the local peer review organization. Overall, physicians at the Scottsdale Memorial Hospital (SMH) approved 72% of HSAG-approved and denied 61% of HSAG-denied admissions. Of the 64 admissions, 3 or 4 of 4 reviewers (2 physicians and 2 nurses) agreed with the HSAG decision in 38 (59%), but 2 or more reviewers disagreed in the other 26 (41%). Disagreement between the 2 physicians occurred in 48% of the cases and disagreement between the 2 nurses in 33%. Even among admissions denied by SMH physician reviewers, the physicians would have admitted 23% of those patients under similar circumstances. In 28% of the HSAG-denied admissions, the reviewing physicians thought that the patients' health care would have been compromised if the admissions had not taken place. Despite well-defined criteria for the appropriateness of hospital admissions, the review process remains subjective, with much disagreement between peer review organizations and practicing physicians.
