The promise of electronic decision support to promote evidence based practice remains elusive in the context of chronic disease management. We examine the problem of achieving a close relationship of Electronic Health Record (EHR) content to other components of a clinical information system (guidelines, decision support and workflow), particularly linking the decisions made by providers back to...

In our previous work, the effect of use of a water soluble CDI/NHS system as nontoxic cross-linking agent on fabrication of gelatin nanoparticles was investigated. In this research, the effect of variation in some synthetic parameters of gelatin nanoparticles cross-linked by CDI/NHS system such as type of gelatin and formulation of cross- linking agent on their size and distribution was examine...

Linking a health and demographic surveillance system (HDSS) to data from a health facility that serves the HDSS population generates a research infrastructure for directly observed data on access to and utilization of health facility services. Many HDSS sites, however, are in areas that lack unique national identifiers or suffer from data quality issues, such as incomplete records, spelling err...

We present an account of an undergraduate team based assignment designed to facilitate, exhibit and record team working skills in an e-mediated environment. By linking the student feedback received to Hofstede’s classic model of cultural dimensions we aim to show the assignment’s suitability in revealing the student's multi-cultural context. In addition to anecdotal evidence we also present a q...

Data processing can sometimes require complex logic to match and rank record associations across events. This paper presents an efficient solution to generating these complex associations using the DATA step and data hash objects. The solution applies to multiple business needs including subsequent purchases, repayment of loan advance, or hospital readmits. The logic demonstrates how to constru...

Structured reporting systems use standardized data elements and predetermined data-entry formats to record observations. This article describes a system for structured data entry and reporting that generates reports encoded in the Standard Generalized Markup Language (SGML), an open, internationally accepted standard for document interchange. The structured report is self-documenting: it includ...

We review the theory and techniques of record linkage that date back to pioneering work by Fellegi and Sunter on matching records in two lists. When the task involves linking K > 2 lists, the most common approach consists of performing all ( K 2 ) possible pairs of lists using a Fellegi-Sunter-like approach and then somehow reconciling the discrepancies in an ad hoc fashion. We describe some im...

Separation logic (SL) is an extension of Hoare logic by operations and formulas that not only talk about program variables, but also about heap portions. Its general purpose is to enable more flexible reasoning about linked object/record structures. In the present paper we give an algebraic extension of SL at the data structure level. We define operations that additionally to heap separation ma...
