To improve identification of pertussis cases by developing a decision model that incorporates recent, local, population-level disease incidence.

To assess physicians' attitudes toward health information exchange (HIE) and physicians' willingness to pay to participate in HIE.

Improvements in electronic health record (EHR) system development will require an understanding of psychiatric clinicians' views on EHR system acceptability, including effects on psychotherapy communications, data-recording behaviors, data accessibility versus security and privacy, data quality and clarity, communications with medical colleagues, and stigma.

Clinicians are required to report selected conditions to public health authorities within a stipulated amount of time. The current reporting process is mostly paper-based and inefficient and may lead to delays in case investigation. As electronic medical records become more prevalent, electronic case reporting is becoming increasingly feasible. However, there is no existing standard for the electronic transmission of case reports from healthcare to public health entities. We identified the [...]

In 2007, the Department of Health and Human Services commissioned the Nationwide Health Information Network (NHIN) Trial Implementations project to demonstrate the secure exchange of data among health information exchange organizations around the country. The project's Core Services Content Work Group (CSCWG) developed the content specifications for the project. The CSCWG developed content specifications for a summary patient record and for eight use cases that were implemented in demonstration events [...]

An object identifier (OID) has a central utility in providing a traceable source for the meaning of an identifier appearing in a cross-system communication. The views in this paper illustrate the problems with using the present OID registration system as a reliable source for the identifier, the confusion that the use of an OID introduces in messages, and the redundancy that the OID introduces at the expense of increased message [...]

Maintaining a large controlled biomedical vocabulary requires ensuring the content's internal consistency. This is done through rules, specified by the vocabulary's curators, which denote how the vocabulary's concepts should be defined. When individual organizations deploy such vocabularies, local concepts are typically added and linked to concepts in the main vocabulary: the process of maintaining and linking local content should follow the same rules. The operation of content-maintenance software can be [...]

Electronic medical records (EMRs) facilitate abnormal test result communication through "alert" notifications. The aim was to evaluate how primary care providers (PCPs) manage alerts related to critical diagnostic test results on their EMR screens, and compare alert-management strategies of providers with high versus low rates of timely follow-up of results.

Regional Health Information Organizations (RHIOs) will likely play a key role in our nation's effort to catalyze health information exchange. Yet we know little about why some efforts succeed while others fail. We sought to identify factors associated with RHIO viability.

To formulate a model for translating manual infection control surveillance methods to automated, algorithmic approaches.
