OBJECTIVE To evaluate the reliability and validity of Korean version of AST (K-AST) as a bedside screening test of apraxia in patients with stroke for early and reliable detection. METHODS AST was translated into Korean, and the translated version received authorization from the author of AST. The performances of K-AST in 26 patients (21 males, 5 females; mean age 65.42±17.31 years) with stro...

To assess the validity of performance measures used in a nationwide pay-forperformance (P4P) project on hip and knee replacement, we analyzed hospital performance data from a Medicare P4P initiative and compared them to publicly available outcomes data. Overall, the ability to measure hospital quality was poor. A hospital’s ranking on the composite score was primarily determined by process meas...

BACKGROUND Recent initiatives have focused on reducing door-to-balloon (DTB) times among patients with acute myocardial infarction undergoing primary percutaneous coronary intervention. However, DTB time is only one of several important AMI care processes. It is unclear whether quality efforts targeted to a single process will facilitate concomitant improvement in other quality measures and out...

Rationale: HF is the leading cause of hospitalization among Medicare beneficiaries and is associated with considerable risk of morbidity and mortality. Although HF is a progressive illness for which death may be an inevitable consequence rather than a marker of poor quality, clinical experience suggests that the care for these patients is highly variable and studies suggest gaps in quality of h...

background: measurement of patients’ satisfaction as a reliable indicator of quality of hospital service shows the ability of care providers to meet patients' expectations. this study was conducted to assess patients’ satisfaction in hospital services. methods:  this cross-sectional study was carried out at the zanjan university of medical sciences in 2013 -2014. a total of 486 were select...

Hospitals are a symbol of social welfare and the last refuge of patients, which is the most important issue of the health system. Patient safety is the first and most important issue for the health system.  Before COVID-19, the World Health Organization (WHO) defined the Hospital Safety Index (HSI) to measure hospital preparedness for disasters. During the COVID-19 crisis, hospitals faced many ...

We study a continuous-time financial market with continuous price processes under model uncertainty, modeled via a family P of possible physical measures. A robust notion NA1(P) of no-arbitrage of the first kind is introduced; it postulates that a nonnegative, nonvanishing claim cannot be superhedged for free by using simple trading strategies. Our first main result is a version of the fundamen...

OBJECTIVES To use data from the 2001-2 National Stroke Audit to describe the organisation of stroke units in England, Wales and Northern Ireland, and to see if key characteristics deemed effective from the research literature were present. DESIGN Data were collected as part of the National Sentinel Audit of Stroke in 2001, both on the organisation and structure of inpatient stroke care and th...

BACKGROUND The performance of the Charlson and Elixhauser comorbidity measures in predicting patient outcomes have been well validated with ICD-9 data but not with ICD-10 data, especially in disease specific patient cohorts. The objective of this study was to assess the performance of these two comorbidity measures in the prediction of in-hospital and 1 year mortality among patients with conges...
