Pediatric emergency department crowding: survival tree clustering for length of patient stay.
The objective of this study is to analyse the length of patient stay in Pediatric emergency department according to diagnosis and the number of patients over a 3 year-period. A survival tree was used, to explore the underlying construct of overcrowding depending of the length of patient stay. ⋯ The hazard ratio test was used to determine optimal partition. The approach is illustrated using Electronic Medical Record Software database available at the Pediatric Emergency Department of Lille University Hospital.

A reference data model of a metadata registry preserving semantics and representations of data elements.
Integration and analysis of clinical data collected in multiple data sources over a long period of time is a major challenge even when data warehouses and metadata registries are used. Since most metadata registries focus on describing data elements to establish domain consistent data definition and providing item libraries, hierarchical and temporal dependencies cannot be mapped. Therefore we developed and validated a reference data model, based on ISO/IEC 11179, which allows revision and branching control of conceptually similar data elements with heterogeneous definitions and representations.

ReviewFrailty, Physical Frailty, Sarcopenia: A New Conceptual Model.
In the literature, different criteria have been validated to identify frail older subjects, which mainly refer to two conceptual models: the cumulative deficit approach proposed by Rockwood and the Physical Frailty (PF) phenotype proposed by Fried. Both models have received empirical validation. Nevertheless, the frailty phenotype is the most widely used and presents a characterized pathophysiologic background. ⋯ Therefore, sarcopenia may be considered both as the biological substrate for the development of PF and the pathway through which the negative health outcomes of frailty ensue. Although PF encompasses only a part of the frailty spectrum, the identification of a definite biological basis (i.e., skeletal muscle decline) opens new venues for the development of interventions to slow or reverse the progression of this condition. Here, we present a novel conceptualisation of PF which will possibly promote significant advancements over the traditional approaches to this syndrome by enabling the precise operationalisation of the condition, a clear identification of the affected population and the rapid translation of findings to the clinical arena.

Pre-implementation investigation of the readiness of allied health professionals to adopt electronic health records.
There has been limited uptake of electronic health records (EHR) by allied health professionals. Yet, not much attention has been given to their information needs. For EHR to work for these health professionals, it is essential to understand their current practice of information management and their perceptions towards EHR. ⋯ It appears that allied health professionals today are information technology (IT) savvy and ready to adopt EHR. EHR for allied health practices in Australia are long overdue. The health informatics community can no longer ignore the need and want of allied health professionals for EHR that are tailored and built to support their information and practice management.

A model for consent-based privilege management in personal electronic health records.
One of the biggest issues in the domain of standardized, regional, crossinstitutional, personal, electronic health records is the privilege management. While many health information exchange projects use IHE-based architectures there are still unsolved questions regarding the restricting parameters a patient can use in the electronic consent configuring access control. ⋯ The introduced model can serve as framework for health information exchanges using a consent-based privilege management. The set representation can help to understand the complexity of consent representations.
