Statistical issues in reporting quality data: small samples and casemix variation

Statistical issues in reporting quality data: small samples and casemix variation.

PURPOSE To present two key statistical issues that arise in analysis and reporting of quality data. SUMMARY Casemix variation is relevant to quality reporting when the units being measured have differing distributions of patient characteristics that also affect the quality outcome. When this is the case, adjustment using stratification or regression may be appropriate. Such adjustments may be...

Quality and payment: the U.S. experience of typing inpatient and outpatient casemix payments to quality measures and reporting

Introduction Over the past four to five years, the focus in casemix-based payment systems in the United States has shifted more and more towards "value-based-purchasing" and "payfor-performance" measures. The reporting of pre-set quality indicators is now fundamentally in place for both the inpatient prospective-payment system, based on Medicare-Severity Diagnosis Related Groups (MS-DRGs), and,...

Data Quality Issues in Visualization

Recent eeorts in visualization have concentrated on high volume data sets from numerical simulations and medical imaging. There is another large class of data, characterized by their spatial sparsity with noisy and possibly missing data points, that also need to be visualized. Two places where these type of data sets can be found are in oceanographic and atmospheric science studies. In such cas...

: metadiscourse in introduction sections of applied linguistics and physics research articles: exploring variation in frequency and type

abstract in written mode of language, metadiscourse markers are used commonly to help writers in general and academic writers in particular to produce coherent and professional texts. the purpose of the present study was to compare introduction sections of applied linguistics and physics articles regarding their use of interactive and interactional metadiscourse markers based on the model pro...
