Abstract

As part of preliminary studies for the development of a digital library, we have studied the possibility of using the co-occurrence of MeSH terms in MEDLINE citations associated with the search strategies optimal for evidence-based medicine to automate construction of a knowledge base. We use the UMLS semantic types in order to analyze search results to determine which semantic types are most relevant for different types of questions (etiology, diagnosis, therapy, and prognosis). The automated process generated a large amount of information. Seven to eight percent of the semantic pairs generated in each clinical task group co-occur significantly more often than can be accounted for by chance. A pilot study showed good specificity and sensitivity for the intended purposes of this project in all groups.

Medicare program; electronic submission of cost reports. Final rule.

This final rule amends regulation by requiring that, for cost reporting periods ending on or after December 31, 2004, all hospices, organ procurement organizations, rural health clinics, Federally qualified health centers, community mental health centers, and end-stage renal disease facilities must submit cost reports currently required under the Medicare regulations in a standardized electronic format. This rule also allows a delay or waiver of this requirement when implementation would result in financial hardship for a provider. The provisions of this rule allow for more accurate preparation and more efficient processing of cost reports.

Modular data logger system for physical workload measurements.

Direct technical measurements of physical workload have advantages in studies of work-related musculoskeletal disorders. A data logger has been developed, based on 20 and 40 Mbyte PCMCIA (Personal Computer Memory Card International Association) flash memory cards, for electromyography (EMG), inclinometry and goniometry. They are provided with an input for marking of events that can be used for synchronization with other loggers and with video recordings. To make the data easier to access by the preceeding analysis software, application software has also been developed that reorganizes the data. The loggers are easy to operate and enable whole-day ambulatory field recordings without any need for reduction or compression of the data.
