Evaluating and improving the measurement
This issue of Health Care Financing Review is devoted entirely to the accuracy of hospital case-mix measurement systems for reimbursing hospitals. We have brought together eight articles by active workers in this field, representing the most promising efforts to improve case-mix measurement. Although severity of illness is an organizing theme for these articles, their scope is much broader. The...
متن کاملEvaluating and improving the measurement of hospital case mix
The foundation of case-based prospective payment is the case classification system. The purpose of classification systems is to group together patients with similar treatment requirements. The systems described in this issue take a variety of theoretical and practical approaches to classification. The critical issue in comparing these systems is whether the variation in treatment requirements w...
متن کاملImproving the measurement performance for a self-mixing interferometry-based displacement sensing system.
Approaches that are, to our knowledge, novel, are proposed in this paper to improve the accuracy performance of self-mixing interferometry (SMI) for displacement measurement. First, the characteristics associated with signals observed in SMI systems are studied, based on which a new procedure is proposed for achieving accurate estimation of the laser phase. The studies also revealed the reasons...
متن کاملLaser Doppler Displacement Measurement
Existing precision displacement-measuring devices are primarily based on linear encoders (optical or magnetic) or laser interferometers. Most encoders use grating scales and frequency counters, while most interferometers use stabilized lasers and fringe counters. In general, interferometers are more expensive and more accurate than linear encoders. However, there are large gaps in price and per...
متن کاملDesign and Simulation of piezorestive pressure sensor for AFM Probe the displacement measurement
investigating pressure applied in surface vertically that is done by use of mechanical procedures isn’t efficient to measure pressure applied in inner surface of reservoir or pipes having gas due to entering pressure into whole walls and different surfaces. So, in order to measure this kind of pressure, several studies were conducted in past decades and also various procedures were proposed tha...
