We imported an automated APACHE II scoring system developed at another institution. We scored a convenience sample of 50 consecutive intensive care unit (ICU) admissions using three methods: (1) the automated system (2) an expert scorer using a manual data abstraction method, and (3) the current manual scoring method used in the ICU. We analyzed interrater reliability among the three groups, and compared scoring time between the automated and the expert groups. Interrater reliability testing demonstrated a very high agreement between the computer and the expert scorers, (r = 0.97 p < 0.01) and a high agreement between the computer and the nursing staff (r = 0.80, p < 0.01). The mean time required to complete the data sheet manually and input data into a standalone computer manually was 4 minutes and 55 seconds, compared to total mean time of 33 seconds for the automated system. Automated APACHE II scoring yielded results more reliable than those of an expert scorer, as judged by a second researcher. The time required to score patients was reduced and reliability of scores was improved with use of an automated APACHE II scoring system.","PeriodicalId":79455,"journal":{"name":"Proceedings : a conference of the American Medical Informatics Association.

Modeling mechanical cardiopulmonary interactions for virtual environments. 虚拟环境中机械心肺相互作用的建模。

{"title":"Modeling mechanical cardiopulmonary interactions for virtual environments.","authors":"J M Kaye","doi":"","DOIUrl":"","url":null,"abstract":"We have developed a computer system for modeling mechanical cardiopulmonary behavior in an interactive, 3D virtual environment. The system consists of a compact, scalar description of cardiopulmonary mechanics, with an emphasis on respiratory mechanics, that drives deformable 3D anatomy to simulate mechanical behaviors of and interactions between physiological systems. Such an environment can be used to facilitate exploration of cardiopulmonary physiology, particularly in situations that are difficult to reproduce clinically. We integrate 3D deformable body dynamics with new, formal models of (scalar) cardiorespiratory physiology, associating the scalar physiological variables and parameters with corresponding 3D anatomy. Our approach is amenable to modeling patient-specific circumstances in two ways. First, using CT scan data, we apply semi-automatic methods for extracting and reconstructing the anatomy to use in our simulations. Second, our scalar models are defined in terms of clinically-measurable, patient-specific parameters. This paper describes our approach and presents a sample of results showing normal breathing and acute effects of pneumothoraces.","PeriodicalId":79455,"journal":{"name":"Proceedings : a conference of the American Medical Informatics Association.

Our consortium collected 10,538 clinical narratives from patient problem lists recorded at 65 Veterans Hospitals, internal medicine ambulatory care practices, diagnostic history and physical examination data elements from Iliad, and nursing shift notes and emergency transport patient records. The results showed 94% of submitted terms resulted in acceptable matches. 49% of submitted terms were judged to be synonymous with the match terms, 35% were judged to be more specific (usually due to modifiers), 2%, were less specific, and 6% had an associative relationship. In 8% of cases either no match was found by the LSVT interface or all proposed matches were rejected by the raters. The LSVT content was quite suitable for coding our narratives. Necessary improvements for an electronic record would include the ability to compose modifiers together with root concepts.","PeriodicalId":79455,"journal":{"name":"Proceedings : a conference of the American Medical Informatics Association.

We tested this method in 52 healthy volunteers using a computer-based interview that trained subjects in standard gamble (SG) and WTP methods, and elicited preferences for moderate Gaucher disease using WTP and SG. We assessed the validity of the WTP method by calculating the cost-effectiveness threshold implied by subjects' WTP and SG utilities; we also assessed subjects' understanding and comfort with using WTP for decision making by a questionnaire. The WTP method had good test-retest reliability (r = 0.796), and produced a cost-effectiveness ratio and ratings for understanding and clarity that support its validity. Moreover, many subjects felt that WTP was a reasonable (83%) method for therapeutic decision making and expressed comfort (62%) in using the method for their own health care decisions. These results suggest that a probabilistic method for WTP utility assessment is potentially useful for acquiring patient preferences for use in normative decision support systems.","PeriodicalId":79455,"journal":{"name":"Proceedings : a conference of the American Medical Informatics Association.
