Health examinations play a key role in preventive medicine. We propose a health examination system named Health Examination
Automatic Logic System (HEALS) to assist clinical workers in improving the total quality of health examinations. Quality of
automated inference is confirmed by the zero inference error where during 6 months and 14,773 cases. Automated inference time
is less than one second per case in contrast to 2 to 5 min for physicians. The most significant result of efficiency evaluation
is that 3,494 of 4,356 (80.2%) cases take less than 3 min per case for producing a report summary. In the evaluation of effectiveness,
novice physicians got 18% improvement in making decisions with the assistance of our system. We conclude that a health examination
system with a clinical decision system can greatly reduce the mundane burden on clinical workers and markedly improve the
quality and efficiency of health examination tasks. 相似文献

Reduction of health care costs is of paramount importance in our time. This paper is a part of the research which proposes an expert hospital decision support system for resource scheduling. The proposed system combines mathematical programming, knowledge base, and database technologies, and what is more, its friendly interface is suitable for any novice user. Operating rooms in hospitals represent big investments and must be utilized efficiently. In this paper, first a mathematical model similar to job shop scheduling models is developed. The model loads surgical cases to operating rooms by maximizing room utilization and minimizing overtime in a multiple operating room setting. Then a prototype expert system which replaces the expertise of the operations research analyst for the model, drives the modelbase, database, and manages the user dialog is developed. Finally, an overview of the sequencing procedures for operations within an operating room is also presented. 相似文献

Background Existing hospital information systems with simple statistical functions cannot meet current management needs. It is well known that hospital resources are distributed with private property rights among hospitals, such as in the case of the regional coordination of medical services. In this study, to integrate and make full use of medical data effectively, we propose a data warehouse modeling method for the hospital information system. The method can also be employed for a distributed-hospital medical service system.
Methods To ensure that hospital information supports the diverse needs of health care, the framework of the hospital information system has three layers: datacenter layer, system-function layer, and user-interface layer. This paper discusses the role of a data warehouse management system in handling hospital information from the establishment of the data theme to the design of a data model to the establishment of a data warehouse. Online analytical processing tools assist user-friendly multidimensional analysis from a number of different angles to extract the required data and information.
Results Use of the data warehouse improves online analytical processing and mitigates deficiencies in the decision support system. The hospital information system based on a data warehouse effectively employs statistical analysis and data mining technology to handle massive quantities of historical data, and summarizes from clinical and hospital information for decision making.
Conclusions This paper proposes the use of a data warehouse for a hospital information system, specifically a data warehouse for the theme of hospital information to determine latitude, modeling and so on. The processing of patient information is given as an example that demonstrates the usefulness of this method in the case of hospital information management. Data warehouse technology is an evolving technology, and more and more decision support information extracted by data mining and with decision-making technology is required for further research.

In this evolving ‘third era of health’, one of the US Health Care Reform Act’s goals is to effectively facilitate the primary care physician’s ability to better diagnose and manage the health outcome of the outpatient. That goal must include research on the complementary quantitative-qualitative assessment and rating of the patient’s health status. This paper proposes an overview of the rationale and design of a research program for a balanced measurement and diagnostic clinical decision support system (CDSS) of the changing general health status of the patient -including disease- using electronic health record (EHR) data. The rationale, objectives, health metric-diagnostic tools architecture, simulation-optimization, and clinical trials are outlined. Resources, time frames, costs, feasibility, healthcare benefits and data-integration of the project are delineated. The basis and components of the research program to achieve an automated-CDSS to complement physician’s clinical judgment, calculating a mathematical ‘health equation’ from each patient’s EHR database, assisting physician-patient collaboration to diagnose, and improve general health outcomes is described. Use of multiple dimensional index, ways of classification, and causal factors’ assessments, to arrive at the EHR-based CDSS algorithm-software providing a general health level and state rating of the patient are proposed. Its application could provide a compass for the general practitioner’s best choice and use of the myriad of healthcare educational and technological options available with lower costs for everyday clinical practice and research. It could advance the approaches and focus of the ‘eras of diseases’, to the promising ‘era of health’, in an integrated, general approach to ‘health.’ 相似文献

School health developed gradually over the years; starting with efforts to keep contagion out of schools to global programs of comprehensive services. One of its components, school medicine, covers screening examinations, record maintenance, emergency care, immunization monitoring and health counseling. This paper proposes the essential health activities to be performed during a screening school examination in Lebanon. The recommendations are based on a combination of international literature review of evidence and the existence of Lebanese epidemiological reports identifying specific problems. Vaccination record review, tuberculin testing, vision, hearing, dental and skin disorders screening procedures are proposed as essential activities of the school physical examination. 相似文献

The objective of this work is to develop and implement a computer-aided decision support system for an automated diagnosis
and classification of ultrasound kidney images. The proposed method distinguishes three kidney categories namely normal, medical
renal diseases and cortical cyst. For the each pre-processed ultrasound kidney image, 36 features are extracted. Two types
of decision support systems, optimized multi-layer back propagation network and hybrid fuzzy-neural system have been developed
with these features for classifying the kidney categories. The performance of the hybrid fuzzy-neural system is compared with
the optimized multi-layer back propagation network in terms of classification efficiency, training and testing time. The results
obtained show that fuzzy-neural system provides higher classification efficiency with minimum training and testing time. It
has also been found that instead of using all 36 features, ranking the features enhance classification efficiency. The outputs
of the decision support systems are validated with medical expert to measure the actual efficiency. The overall discriminating
capability of the systems is accessed with performance evaluation measure, f-score. It has been observed that the performance
of fuzzy-neural system is superior compared to optimized multi-layer back propagation network. Such hybrid fuzzy-neural system
with feature extraction algorithms and pre-processing scheme helps in developing computer-aided diagnosis system for ultrasound
kidney images and can be used as a secondary observer in clinical decision making. 相似文献

As general physician one can significantly influence a mother's or family's decision to optimally feed their baby and good feeding practices during first year greatly reduce the risk of a child being sick and being malnourished. It is recommended that health personnel should focus on exclusive breastfeeding for first six months and continued breastfeeding for up to two years along with appropriate and timely complementary foods that are started at the age of six months. Mothers need breastfeeding information and support during antenatal time; during hospital stay or at health care facility, and during postpartum visits. Encouragement especially during antenatal period increases breastfeeding rates. Subsequent paediatric and matemal visits are also important for promotion of breastfeeding. In this paper we would provide you new and updated information on recommended feeding practices, how you can support and help mothers, and what kind of skilled help is needed to initiate breastfeeding early, maintain exclusive breastfeeding and avoid artificial feeding. We will also discuss some strategies to support mothers. 相似文献
