The RxData project collects drug dispensing information from member hospitals and joins it to administrative discharge data in the Chime database. The resulting dataset is useful for descriptive epidemiology of drug use patterns as well as surveillance, quality improvement, and some hypothesis testing. The drug identity is derived from the National Drug Code submitted by hospital pharmacies. A drug reference file is used together with these codes for hierarchical analysis. Data are accepted from participating facilities in a variety of formats and mapped to a common schema. The program uses locally developed roll-up logic to overcome the lack of consistent standards for recording inpatient drug order and dispense information. Dispensing records at different levels of aggregation are collected from source pharmacy information systems and converted to a standard \"regimen\" based on continuous dispensing of the same drug. The resulting record structure allows direct comparison of data from dissimilar systems. Data are currently available for eleven acute care hospitals and most of their associated emergency and outpatient surgery facilities. The program is expected to expand to cover most if not all Connecticut hospitals over the next two to three years.</p>","PeriodicalId":79712,"journal":{"name":"Proceedings.

The overall goal of the Health@Home project is to improve the functionality and content of information technology innovations for the home.

Selective retrieval of pre- and post-coordinated SNOMED concepts. 选择性检索前后协调的SNOMED概念。

{"title":"Selective retrieval of pre- and post-coordinated SNOMED concepts.","authors":"Robert H Dolin,&nbsp;Kent A Spackman,&nbsp;David Markwell","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>In general, it is very straightforward to store concept identifiers in electronic medical records and represent them in messages. Information models typically specify the fields that can contain coded entries. For each of these fields there may be additional constraints governing exactly which concept identifiers are applicable. However, because modern terminologies such as SNOMED CT are compositional, allowing concept expressions to be pre-coordinated within the terminology or post-coordinated within the medical record, there remains the potential to express a concept in more than one way. Often times, the various representations are similar, but not equivalent. This paper describes an approach for retrieving these pre- and post-coordinated concept expressions: (1) Create concept expressions using a logically-well-structured terminology (e.g., SNOMED CT) according to the rules of a well-specified information model (in this paper we use the HL7 RIM); (2) Transform pre- and post-coordinated concept expressions into a normalized form; (3) Transform queries into the same normalized form. The normalized instances can then be directly compared to the query. Several implementation considerations have been identified. Transformations into a normal form and execution of queries that require traversal of hierarchies need to be optimized. A detailed understanding of the information model and the terminology model are prerequisites. Queries based on the semantic properties of concepts are only as complete as the semantic information contained in the terminology model. Despite these considerations, the approach appears powerful and will continue to be refined.</p>","PeriodicalId":79712,"journal":{"name":"Proceedings.

However, there are many more recommended preventive services than can be practically included in a typical clinic visit. Therefore prioritization of preventive services prompts is necessary. We describe two approaches to prioritizing preventive services prompts based on expected value decision making. One method involves a static, global prioritization across all preventive services and has been used in a production system for almost 7 years. The second method uses influence diagrams to prioritize prompts dynamically, based on individual patient data. The latter approach is still under development. Both methods are labor intensive and require a combination of epidemiologic data and expert judgment.
