To describe the clinical characteristics and outcomes of a large, multicenter cohort of pediatric medical emergency team (MET) events occurring in US hospitals reported to the American Heart ...Association's Get With the Guidelines-Resuscitation registry.
We analyzed consecutive pediatric (<18 years) MET events reported to the registry from January 2006 to February 2012.
We identified 3647 MET events from 151 US hospitals: 3080 (84%) ward and 567 (16%) telemetry/step-down unit events; median age 3.0 years (interquartile range: 0.0-11.0); 54% male; median duration 29 minutes (interquartile range: 18-49). Triggers included decreased oxygen saturation (32%), difficulty breathing (26%), and staff concern (24%). Thirty-seven percent (1137/3059) were admitted within 24 hours before MET event. Within 24 hours before the MET event, 16% were transferred from a PICU, 24% from an emergency department, and 7% from a pediatric anesthesia care unit. Fifty-three percent of MET events resulted in transfer to a PICU; 3251 (89%) received nonpharmacologic interventions, 2135 (59%) received pharmacologic interventions, 223 (6.1%) progressed to an acute respiratory compromise event, and 17 events (0.5%) escalated to cardiopulmonary arrest during the event. Survival to hospital discharge was 93.3% (n=3299/3536).
Few pediatric MET events progress to respiratory or cardiac arrest, but most require nonpharmacologic and pharmacologic intervention. Median duration of MET event was 29 minutes (interquartile range: 18-49), and 53% required transfer to a PICU. Events often occurred within 24 hours after hospital admission or transfer from the PICU, emergency department, or pediatric anesthesia care unit and may represent an opportunity to improve triage and other systems of care.
An understanding of the time course and correlation with injury of heat shock proteins (HSPs) released during brain and/or spinal cord cellular stress (ischemia) is critical in understanding the role ...of the HSPs in cellular survival, and may provide a clinically useful biomarker of severe cellular stress. We have analyzed the levels of HSPs in the cerebrospinal fluid (CSF) from patients who are undergoing thoracic aneurysm repair. Blood and CSF samples were collected at regular intervals, and CSF was analyzed by enzyme-linked immunosorbent assay for HSP70 and HSP27. These results were correlated with intraoperative somatosensory-evoked potentials measurements and postoperative paralysis. We find that the levels of these proteins in many patients are elevated and that the degree of elevation correlates with the risk of permanent paralysis. We hypothesize that sequential measurement intraoperatively of the levels of the heat shock proteins HSP70 and HSP27 in the CSF can predict those patients who are at greatest risk for paralysis during thoracic aneurysm surgery and will allow us to develop means of preventing or attenuating this severe and often fatal complication.
To determine whether, on a national cytology proficiency test, a competent cytologist can consistently distinguish grades of squamous intraepithelial lesions.
Results for low- and high-grade squamous ...intraepithelial lesion referenced slides from the College of American Pathologists Interlaboratory Comparison Program in Cervicovaginal Cytology for 1996 and 1997 were analyzed including educational, nongraded vs graded validated slides.
The discrepant rate between low- and high- grade lesions ranged from 9.8% to 15% for cytotechnologist, pathologist, laboratory, and all responses. There was a statistically significant difference in performance on graded, validated slides vs educational slides with better performance on validated slides.
This significant interobserver variability in subclassification of squamous lesions should be considered in management guidelines for abnormal Papanicolaou test results and implementation of national cytology proficiency testing.
To describe longitudinal trends in the efficiency, labor productivity, and utilization of clinical laboratories in the United States.
Financial and activity data were prospectively collected from 73 ...clinical laboratories continuously enrolled in the College of American Pathologists Laboratory Management Index Program from 1994 through 1999. Each laboratory reported quarterly on its costs, labor inputs, and test activity using uniform data definitions.
During the 6-year study period, there was a significant increase in laboratory labor productivity (2.1% more tests/full-time equivalent/y; P <.001). Productivity increases were offset by increasing labor expense (1.5%/full-time equivalent/y; P <.001), consumable expense (1.7%/on-site test/y; P =.005), and blood expense, which comprised more than 10% of laboratory expenses by 1999 (4.4% increase/y; P <.001). As a result, overall expense per test showed no significant change in non-inflation-adjusted dollars. Reference laboratory expense per test did not change significantly during the study period; the proportion of tests sent to reference laboratories grew slightly (0.06% increase/y; P <.001). Test volume of the median laboratory grew by 5442 tests per year (2.3% annual increase; P <.001), while the proportion of testing from inpatients declined by 1.7% per year (P <.001). Inpatient test utilization declined on a discharge basis (annual decline of 1.2 tests/inpatient discharge; P <.001) and on a per diem basis (annual decline of 0.08 tests/inpatient day; P =.002). Inpatient laboratory expense declined on a discharge basis (annual decline of $2.40 or 1.3% per discharge; P <.001), but did not change significantly per inpatient day. Most of the reduction in the expense per discharge occurred during 1994-1996.
Between 1994 and 1999, clinical laboratories in the United States experienced significant changes in the cost of operations, utilization, and labor productivity. Laboratory administrators who compare local institutional performance with that of peers are advised to use current or forward-trended peer data. Quarter-to-quarter improvement in many measures of laboratory financial activity may not signal a superior operation, as performance of the whole industry appears to be improving.
