Utilizing RxNorm to Support Practical Computing Applications: Capturing Medication History in Live Electronic Health Records
RxNorm was utilized as the basis for direct-capture of medication history
data in a live EHR system deployed in a large, multi-state outpatient
behavioral healthcare provider in the United States serving over 75,000
distinct patients each year across 130 clinical locations. This tool
incorporated auto-complete search functionality for medications and proper
dosage identification assistance. The overarching goal was to understand if and
how standardized terminologies like RxNorm can be used to support practical
computing applications in live EHR systems. We describe the stages of
implementation, approaches used to adapt RxNorm's data structure for the
intended EHR application, and the challenges faced. We evaluate the
implementation using a four-factor framework addressing flexibility, speed,
data integrity, and medication coverage. RxNorm proved to be functional for the
intended application, given appropriate adaptations to address high-speed
input/output (I/O) requirements of a live EHR and the flexibility required for
data entry in multiple potential clinical scenarios. Future research around
search optimization for medication entry, user profiling, and linking RxNorm to
drug classification schemes holds great potential for improving the user
experience and utility of medication data in EHRs.Comment: Appendix (including SQL/DDL Code) available by author request.

The Standard Problem
Crafting, adhering to, and maintaining standards is an ongoing challenge.
This paper uses a framework based on common models to explore the standard
problem: the impossibility of creating, implementing or maintain definitive
common models in an open system. The problem arises from uncertainty driven by
variations in operating context, standard quality, differences in
implementation, and drift over time. Fitting work by conformance services
repairs these gaps between a standard and what is required for interoperation,
using several strategies: (a) Universal conformance (all agents access the same
standard); (b) Mediated conformance (an interoperability layer supports
heterogeneous agents) and (c) Localized conformance, (autonomous adaptive
agents manage their own needs). Conformance methods include incremental design,
modular design, adaptors, and creating interactive and adaptive agents. Machine
learning should have a major role in adaptive fitting. Choosing a conformance
service depends on the stability and homogeneity of shared tasks, and whether
common models are shared ahead of time or are adjusted at task time. This
analysis thus decouples interoperability and standardization. While standards
facilitate interoperability, interoperability is achievable without
standardization.Comment: Keywords: information standard, interoperability, machine learning,

Improve Intra-Operative Nurse-to-Nurse Communication Using a Safety Checklist
Poor and inadequate handoff, or transfer of care of the surgical patient care from the primary to the relief operating room registered nurse circulators, can result in irreversible patient harm, or sentinel events, such as retained foreign items. In this study, Rogers\u27 diffusion of innovation theory was the framework for implementing the handoff safety checklist. Also, Donabedian\u27s structure process and outcome was the model to investigate the feasibility, acceptability, and improvement in the quality of patient handoff communication and improvement of nurse satisfaction over time. Nineteen-statement surveys, conducted at multiple timeframes, were completed by volunteer operating room nurse participants. In comparison, outcomes of the pre-intervention and post-intervention surveys illustrated significance in the quality of nurse communication and satisfaction of the handoff safety checklist. The value of standardized handoff safety checklists is evident in the study. However, further research of handoff safety checklists in the intraoperative arena is warranted

Objective: Pharmaceuticals play an important role in clinical care. However, in community-based research, medication data are commonly collected as unstructured free-text, which is prohibitively expensive to code for large-scale studies. The ASPirin in Reducing Events in the Elderly (ASPREE) study developed a two-pronged framework to collect structured medication data for 19,114 individuals. ASPREE provides an opportunity to determine whether medication data can be cost-effectively collected and coded, en masse from the community using this framework. Methods: The ASPREE framework of type-to-search box with automated coding and linked free text entry was compared to traditional method of free-text only collection and post hoc coding. Reported medications were classified according to their method of collection and analysed by Anatomical Therapeutic Chemical (ATC) group. Relative cost of collecting medications was determined by calculating the time required for database set up and medication coding. Results Overall, 122,910 participant structured medication reports were entered using the type-tosearch box and 5,983 were entered as free-text. Free-text data contributed 211 unique medications not present in the type-to-search box. Spelling errors and unnecessary provision of additional information were among the top reasons why medications were reported as freetext. The cost per medication using the ASPREE method was approximately USD 0.20 per medication for the traditional method. Conclusion Implementation of this two-pronged framework is a cost-effective alternative to free-text only data collection in community-based research. Higher initial set-up costs of this combined method are justified by long term cost effectiveness and the scientific potential for analysis and discovery gained through collection of detailed, structured medication data
Approaching Economic Issues through Epidemiology–An Introduction to Business Epidemiology
In the tradition of transferring models and concepts from one science to another, our research explores the possibility of importing some concepts, definitions and approaches from human epidemiology to economic research, based on the extensive usage of medical terms and concepts in economy. The article explores some basic epidemiology concepts and their possible relevance to economic research, with the final goal to provide a new viewpoint over the economic phenomena, usable in economic crisis. The article introduces the concept of “business epidemiology” as a possible scientific approach to the economic crisis.epidemiology; business disease; company health; research methodology; financial contagion

The Internet of Things (IoT) is a dynamic global information network
consisting of internet-connected objects, such as Radio-frequency
identification (RFIDs), sensors, actuators, as well as other instruments and
smart appliances that are becoming an integral component of the future
internet. Over the last decade, we have seen a large number of the IoT
solutions developed by start-ups, small and medium enterprises, large
corporations, academic research institutes (such as universities), and private
and public research organisations making their way into the market. In this
paper, we survey over one hundred IoT smart solutions in the marketplace and
examine them closely in order to identify the technologies used,
functionalities, and applications. More importantly, we identify the trends,
opportunities and open challenges in the industry-based the IoT solutions.
Based on the application domain, we classify and discuss these solutions under
five different categories: smart wearable, smart home, smart, city, smart
environment, and smart enterprise. This survey is intended to serve as a
guideline and conceptual framework for future research in the IoT and to
motivate and inspire further developments. It also provides a systematic
exploration of existing research and suggests a number of potentially
significant research directions.Comment: IEEE Transactions on Emerging Topics in Computing 201
