This article provides an overview of neonatal intensive care unit (NICU) treatment costs. It discusses data sources as well as the methods for measuring costs, contrasting the strengths and weaknesses of alternate approaches. In addition, detailed information on NICU treatment costs is presented from a nationally representative sample of 25 hospitals with NICUs. The sample consists of 3288 very...

The present work concerns the second order ancillary determined by the tangent directions V = ∂y/∂θ|{y0; θ̂(y0)} at the observed data y 0 for fixed pivotal value, by using the structural approach of Fraser (1986). We show that for scalar parameter case, such an approximate ancillary is well defined and can be described as a rotation. These second order ancillaries are particularly useful in prov...

Fluorescent in situ hybridization (FISH) for HER2 performed on paraffin-embedded tissue samples and immunohistochemical analysis for p57 may be useful ancillary studies to aid in the diagnosis and classification of hydatidiform moles (HMs). HER2 FISH was validated against 24 paraffin-embedded sections of HMs and hydropic abortions and showed an 85% concordance rate. A morphologic assessment bas...

This article provides an overview of neonatal intensive care unit treatment costs for hospitals that participated in the Neonatal Intensive Care Quality Improvement Collaborative Year 2000 (NIC/Q 2000) quality improvement collaborative and discusses how economic information can be used in quality improvement efforts. Detailed information on neonatal intensive care unit treatment costs is presen...
