OBJECTIVE To assess the impact of ward or bay closures, specifically, whether prompt closure of an affected ward shortens the duration of norovirus outbreaks and the resulting disruption in hospitals. DESIGN Analysis of summary data from hospitals on outbreaks of norovirus from 2009 to 2012. METHODS Using a large outbreak surveillance dataset, we examined the duration of outbreaks, duration...

In gauge theories, after integrating over the hard modes, the Wilsonian functional depending on the soft fields satisfies effective Ward identities. We observe that, enlarging the Wilsonian functional in order to include hard fields, the effective Ward identities arise from a non-local symmetry between the hard and soft fields. Using the flow equation technique, we outline a proof in perturbati...

The Ward error sum of squares hierarchical clustering method has been very widely used since its first description by Ward in a 1963 publication. It has also been generalized in various ways. Two algorithms are found in the literature and software, both announcing that they implement the Ward clustering method. When applied to the same distance matrix, they produce different results. One algori...

A method of Feynman diagrams summation, based on using Schwinger-Dyson equations and Ward identities, is verified by calculating some four-loop diagrams in N = 1 supersymmetric electrodynamics, regularized by higher derivatives. In particular, for the considered diagrams correctness of an additional identity for Green functions, which is not reduced to the gauge Ward identity, is proved.

BACKGROUND POSSUM and P-POSSUM are used in the assessment of outcomes in surgical patients. Neither scoring systems' accuracy has been established where a level 1 critical care facility (level 1 care ward) is available for perioperative care. We compared POSSUM and P-POSSUM predicted with observed mortality on a level 1 care ward. METHODS A prospective, observational study was performed betwe...

Jeong S, Inoue Y, Kondo K, Matsumoto D, Shiraishi N. Formula for predicting FIM for stroke patients at discharge from an acute ward or convalescent rehabilitation ward. Jpn J Compr Rehabil Sci 2014; 5: 19-25. Objective: To develop formulas for predicting Functional Independence Measure (FIM) at the time of discharge from an acute or convalescent hospital ward using multicenter data. Methods: Da...

Analysis of reports about incidental and accidental events in nursing care were made using a reliability engineering method. Unnatural working hours, such as evening duty, night duty falling next to a holiday, two consecutive night-duty shifts, and two consecutive evening-duty shifts were major factors in the occurrence of errors. In a mixed-division ward (a ward containing patients belonging t...

Aim. The aim was to assess effectiveness of treatment in day-care and inpatient wards within the Wrocław branch of the international multicenter EU-funded EDEN study. Material and methods. The authors analyzed the number of rehospitalisations after discharge from index hospitalisation as well as psychopathologic symptoms and subjective quality of life. Out of 1089 patients admitted to the menta...
