To evaluate the time to communicate laboratory results to health centers (HCs) between the e-Chasqui web-based information system and the pre-existing paper-based system.

The current commercial health information technology (HIT) arena encompasses a number of competing firms that provide electronic health applications to hospitals, clinical practices, and other healthcare-related entities. Such applications collect, store, and analyze patient information. Some vendors incorporate contract language whereby purchasers of HIT systems, such as hospitals and clinics, must indemnify vendors for malpractice or personal injury claims, even if those events are not caused or fostered by the [...]

'Semantic Interoperability' is a driving objective behind many of Health Level Seven's standards. The objective in this paper is to take a step back, and consider what semantic interoperability means, assess whether or not it has been achieved, and, if not, determine what concrete next steps can be taken to get closer. A framework for measuring semantic interoperability is proposed, using a technique called the 'Single Logical Information Model' framework [...]

This case report describes how two complementary standards, CONTsys (European Standard EN 13940-1 for continuity of care) and the reference model of openEHR, were applied in modeling a shared care plan for shared homecare based on requirements from the OLD@HOME project. Our study shows that these requirements are matched by CONTsys on a general level. However, certain attributes are not explicit in CONTsys, for example agents responsible for performing planned [...]

Arizona Medicaid developed a Health Information Exchange (HIE) system called the Arizona Medical Information Exchange (AMIE).

Meaningful use of electronic health records (EHRs) is dependent on accurate clinical documentation. Documenting common goals in the intensive care unit (ICU), such as sedation and ventilator management plans, may increase collaboration and decrease patient length of stay. This study analyzed the degree to which goals stated were present in the EHR.

To facilitate the integration of terminologies into applications, various terminology services application programming interfaces (API) have been developed in the recent past. In this study, three publicly available terminology services API, RxNav, UMLSKS and LexBIG, are compared and functionally evaluated with respect to the retrieval of information from one biomedical terminology, RxNorm, to which all three services provide access. A list of queries is established covering a wide spectrum of [...]

Negation is a linguistic phenomenon that marks the absence of an entity or event. Negated events are frequently reported in both biological literature and clinical notes. Text mining applications benefit from the detection of negation and its scope. However, due to the complexity of language, identifying the scope of negation in a sentence is not a trivial task.

To evaluate the impact of generic substitution decision support on electronic (e-) prescribing of generic medications.
