Developing a sampling method and preliminary taxonomy for classifying COVID-19 public health guidance for healthcare organizations and the general public.

Background: Development and dissemination of public health (PH) guidance to healthcare organizations and the general public (e.g., businesses, schools, individuals) during emergencies like the COVID-19 pandemic is vital for policy, clinical, and public decision-making.

Modeling Contextual Knowledge for Clinical Decision Support.

In theory, the logic of decision rules should be atomic. In practice, this is not always possible; initially simple logic statements tend to be overloaded with additional conditions restricting the scope of such rules. By doing so, the original logic soon becomes encumbered with contextual knowledge.

The Value of Monitoring Clinical Decision Support Interventions.

Background: Well-functioning clinical decision support (CDS) can facilitate provider workflow, improve patient care, promote better outcomes, and reduce costs. However, poorly functioning CDS may lead to alert fatigue, cause providers to ignore important CDS interventions, and increase provider dissatisfaction.

Objective: The purpose of this article is to describe one institution's experience in implementing a program to create and maintain properly functioning CDS by systematically monitoring CDS firing rates and patterns.

A Practical Approach to Governance and Optimization of Structured Data Elements.

Definition and configuration of clinical content in an enterprise-wide electronic health record (EHR) implementation is highly complex. Sharing of data definitions across applications within an EHR implementation project may be constrained by practical limitations, including time, tools, and expertise. However, maintaining rigor in an approach to data governance is important for sustainability and consistency.

Practical choices for infobutton customization: experience from four sites.

Context-aware links between electronic health records (EHRs) and online knowledge resources, commonly called "infobuttons" are being used increasingly as part of EHR "meaningful use" requirements. While an HL7 standard exists for specifying how the links should be constructed, there is no guidance on what links to construct. Collectively, the authors manage four infobutton systems that serve 16 institutions.

Modeling decision support rule interactions in a clinical setting.

Traditionally, rule interactions are handled at implementation time through rule task properties that control the order in which rules are executed. By doing so, knowledge about the behavior and interactions of decision rules is not captured at modeling time. We argue that this is important knowledge that should be integrated in the modeling phase.

Structured representation for core elements of common clinical decision support interventions to facilitate knowledge sharing.

At present, there are no widely accepted, standard approaches for representing computer-based clinical decision support (CDS) intervention types and their structural components. This study aimed to identify key requirements for the representation of five widely utilized CDS intervention types: alerts and reminders, order sets, infobuttons, documentation templates/forms, and relevant data presentation. An XML schema was proposed for representing these interventions and their core structural elements (e.

Supratherapeutic dosing of acetaminophen among hospitalized patients.

Background: We investigated acetaminophen use and identify factors contributing to supratherapeutic dosing of acetaminophen in hospitalized patients.

Methods: We retrospectively reviewed the electronic health records of adult patients who were admitted to 2 academic tertiary care hospitals (hospital A amd hospital B) from June 1, 2010, to August 31, 2010, and who received acetaminophen during their hospitalization. Patients' acetaminophen administration records (including drug name, dose, administration time, hospital units, etc), demographic data, diagnoses, and results from liver function tests were obtained.

A study of diverse clinical decision support rule authoring environments and requirements for integration.

Background: Efficient rule authoring tools are critical to allow clinical Knowledge Engineers (KEs), Software Engineers (SEs), and Subject Matter Experts (SMEs) to convert medical knowledge into machine executable clinical decision support rules. The goal of this analysis was to identify the critical success factors and challenges of a fully functioning Rule Authoring Environment (RAE) in order to define requirements for a scalable, comprehensive tool to manage enterprise level rules.

Methods: The authors evaluated RAEs in active use across Partners Healthcare, including enterprise wide, ambulatory only, and system specific tools, with a focus on rule editors for reminder and medication rules.

Adverse drug events caused by serious medication administration errors.

Objective: To determine how often serious or life-threatening medication administration errors with the potential to cause harm (potential adverse drug events) result in actual harm (adverse drug events (ADEs)) in the hospital setting.

Design: Retrospective chart review of clinical events following observed medication administration errors.

Background: Medication errors are common at the medication administration stage for inpatients.

Fatty emaciation: a case report of suspected fat overload syndrome in oral refeeding.

Refeeding syndrome has been observed in patients receiving nutrition after a prolonged period of malnourishment and is characterized by multiple metabolic derangements. Besides hypophosphatemia and hypoglycemia, lipemia has been described in association with parenteral nutrition administration to the malnourished. The authors describe one anorexic patient who developed lipemia during oral refeeding, followed by a precipitous drop in hematocrit suggestive of fat overload syndrome.

Implementations of the HL7 Context-Aware Knowledge Retrieval ("Infobutton") Standard: challenges, strengths, limitations, and uptake.

Unlabelled: To support clinical decision-making, computerized information retrieval tools known as "infobuttons" deliver contextually-relevant knowledge resources into clinical information systems. The Health Level Seven International (HL7) Context-Aware Knowledge Retrieval (Infobutton) Standard specifies a standard mechanism to enable infobuttons on a large scale.

Objective: To examine the experience of organizations in the course of implementing the HL7 Infobutton Standard.

A legal framework to enable sharing of Clinical Decision Support knowledge and services across institutional boundaries.

The goal of the CDS Consortium (CDSC) is to assess, define, demonstrate, and evaluate best practices for knowledge management and clinical decision support in healthcare information technology at scale - across multiple ambulatory care settings and Electronic Health Record technology platforms. In the course of the CDSC research effort, it became evident that a sound legal foundation was required for knowledge sharing and clinical decision support services in order to address data sharing, intellectual property, accountability, and liability concerns. This paper outlines the framework utilized for developing agreements in support of sharing, accessing, and publishing content via the CDSC Knowledge Management Portal as well as an agreement in support of deployment and consumption of CDSC developed web services in the context of a research project under IRB oversight.

A multi-layered framework for disseminating knowledge for computer-based decision support.

Background: There are several challenges in encoding guideline knowledge in a form that is portable to different clinical sites, including the heterogeneity of clinical decision support (CDS) tools, of patient data representations, and of workflows.

Methods: We have developed a multi-layered knowledge representation framework for structuring guideline recommendations for implementation in a variety of CDS contexts. In this framework, guideline recommendations are increasingly structured through four layers, successively transforming a narrative text recommendation into input for a CDS system.

Creating shareable decision support services: an interdisciplinary challenge.

Creating shareable decision support services is a complex task requiring effort from multiple interdisciplinary role players with a wide variety of experience and expertise. The CDS Consortium research project has developed such a service, defining a multi-layer representation of knowledge and building upon an architectural service design created at Partners Health Care, and is demonstrating its use in both a local and an external institutional setting. The process was iterative, and we encountered unexpected requirements based on decisions made at various points.

Multi-National, Multi-Institutional Analysis of Clinical Decision Support Data Needs to Inform Development of the HL7 Virtual Medical Record Standard.

An important barrier to the widespread dissemination of clinical decision support (CDS) is the heterogeneity of information models and terminologies used across healthcare institutions, health information systems, and CDS resources such as knowledge bases. To address this problem, the Health Level 7 (HL7) Virtual Medical Record project (an open, international standards development effort) is developing community consensus on the clinical information exchanged between CDS engines and clinical information systems. As a part of this effort, the HL7 CDS Work Group embarked on a multinational, collaborative effort to identify a representative set of clinical data elements required for CDS.

A large-scale knowledge management method based on the analysis of the use of online knowledge resources.

Unlabelled: Online health knowledge resources can be integrated into electronic health record systems using decision support tools known as "infobuttons." In this study we describe a knowledge management method based on the analysis of knowledge resource use via infobuttons in multiple institutions.

Methods: We conducted a two-phase analysis of laboratory test infobutton sessions at three healthcare institutions accessing two knowledge resources.

Governance for clinical decision support: case studies and recommended practices from leading institutions.

Objective: Clinical decision support (CDS) is a powerful tool for improving healthcare quality and ensuring patient safety; however, effective implementation of CDS requires effective clinical and technical governance structures. The authors sought to determine the range and variety of these governance structures and identify a set of recommended practices through observational study.

Design: Three site visits were conducted at institutions across the USA to learn about CDS capabilities and processes from clinical, technical, and organizational perspectives.

The morningside initiative: collaborative development of a knowledge repository to accelerate adoption of clinical decision support.

The Morningside Initiative is a public-private activity that has evolved from an August, 2007, meeting at the Morningside Inn, in Frederick, MD, sponsored by the Telemedicine and Advanced Technology Research Center (TATRC) of the US Army Medical Research Materiel Command. Participants were subject matter experts in clinical decision support (CDS) and included representatives from the Department of Defense, Veterans Health Administration, Kaiser Permanente, Partners Healthcare System, Henry Ford Health System, Arizona State University, and the American Medical Informatics Association (AMIA). The Morningside Initiative was convened in response to the AMIA Roadmap for National Action on Clinical Decision Support and on the basis of other considerations and experiences of the participants.

Knowledge management and content integration: a collaborative approach.

Knowledge Management (KM) is the development and maintenance of decision support knowledge within clinical healthcare systems. At Partners Healthcare System (PHS), Knowledge Management is facilitated by a dedicated team consisting of Subject Matter Experts (SME), Knowledge Engineers (KE), and software developers. This group relies upon sound knowledge management principles to support the knowledge lifecycle.

Tiering drug-drug interaction alerts by severity increases compliance rates.

Objective: Few data exist measuring the effect of differentiating drug-drug interaction (DDI) alerts in computerized provider order entry systems (CPOE) by level of severity ("tiering"). We sought to determine if rates of provider compliance with DDI alerts in the inpatient setting differed when a tiered presentation was implemented.

Design: We performed a retrospective analysis of alert log data on hospitalized patients at two academic medical centers during the period from 2/1/2004 through 2/1/2005.

Patient-care questions that physicians are unable to answer.

Objective: To describe the characteristics of unanswered clinical questions and propose interventions that could improve the chance of finding answers.

Design: In a previous study, investigators observed primary care physicians in their offices and recorded questions that arose during patient care. Questions that were pursued by the physician, but remained unanswered, were grouped into generic types.

Cost-benefit analysis of a hospital pharmacy bar code solution.

Background: Bar coding can reduce hospital pharmacy dispensing errors, but it is unclear if the benefits of this technology justify its costs. The purpose of this study was to assess the costs and benefits and determine the return on investment at the institutional level for implementing a pharmacy bar code system.

Methods: We performed a cost-benefit analysis of a bar code-assisted medication-dispensing system within a large, academic, nonprofit tertiary care hospital pharmacy.
