Hospital pharmacy services are divided into dispensing affairs for inpatients and outpatients, pharmaceutical service, stock control, intravenous admixture service, drug information service, pharmacokinetic consultation service, education and research work, etc. But among those affairs, dispensing affair for outpatient is perceived as the most important work in Korea, because it is linked directly with hospital service for patients. Therefore, total computer system for dispensing area was adopted from opening point of hospital in 1989 in Asan Medical Center. Utilization of computer system for outpatient dispensing area is as follows; 1) Order communication system of prescription by Total Hospital Information System, 2) Automatic print-out system of direction for use by sticker connected with on-line net work, 3) Use of automatic tablet counting and packaging machines connected with on-line net work. Those computer system resulted in curtailment of pharmacy manpower and shortening of waiting-time for outpatient.

IT investments of hospitals are growing exponentially and various information systems such as OCS (Order Communication System), EMR (Electronic Medical Record), PACS (Picture Archiving and Communication System), ERP (Enterprise Resource Planning) have been implemented at a number of hospitals in Korea. We have surveyed and analyzed the current status of hospital information systems of major hospitals in Korea, and proposed an information strategy for e-Hospital implementation. Firstly, implementation status of major subsystems of HIS such as OCS, PACS, and EMR has been surveyed and types of IT personnel management have been examined. Based on the field survey result, an information strategy for e-Hospital implementation has been proposed, that can be referenced by hospitals to build their own information strategy. We expect that the study result can contribute to understanding the present status and issues of HIS and information strategy planning of hospitals.

As the adoption of PACS and hospital information system among university hospitals and hospital level institutions grows bigger, the need of sharing and transferring medical information among medical institutions is rising. For the medical information, which is saved in the hospital medical system, to be transferred within the same hospital, domestic, or foreign medical institutions, a standard protocol is necessary. But realistically, most of the domestic hospitals do not abide by H7L which is the HIS standard and so, information transferring is not possible as of present. As such, the purpose of this research is to implement the information between HIS and PACS to an international standard by constructing HL7 messages through HL7 Interface. which will eventually make possible information transferring between different hospitals. Our research team has developed a method which will make the PACS equip hospitals that do not follow HL7 standard which will make possible to transfer information between HIS and PACS through HL7 Message. By constructing message files, which follow the form of HL7 Message in the HL7 Interface, they can be transferred to PACS through the ftp protocol. The realization of the HIS/OCS Interface through HL7 enables data transferring between domestic and foreign medical institutions possible by implementing the international standard in the PACS and HIS data transferring process. The HL7 that our research team has developed made patient data transfer between medical institutions possible. The Interface is for a specific system model and in order for the data transfer between different systems to be realized, interfaces that are fit for each system must be needed. If the interface is improvised and implemented to each hospital's information system, the data sharing among medical institutions can be broadened.

Recently, Hospital information systems have the large databases by wide range offices for hospital management, health care to improve the quality of care. However, hospital information systems for information security measures are insufficient. Therefore, when we construct the hospital information system, we have to audit the information security measures for them, and we have to manage the ISMS(Information Security Management System) to maintain the information protection level through the risk managements. In this paper, we suggested the hospital information security audit model for the protection of health information privacy by the current hospital information systems, information security management system(ISMS), and hospital information security requirements and threats. We derived the check items compared with ISO27799 reflected the characteristics of the hospital. We classified the security domains as the physical, technical, administrative domain, and derived the check items for information security. We also designed the check lists by mapping the ISO27799 risk management process to improve the security and efficiency simultaneously. Our model by the five-point scale survey of IT experts was verified the suitability with the average of 4.91 points.

Many recent changes in medical area such as expansion of medical insurance, high expectation of people for medical service and the competition with foreign country open new area of medical service and hospital managements. Domestic medical personal have been doing their best for better medical service and more efficient hospital management. In other words, they are focusing on the renovation of organization culture, the reform of organization and operation process and building information systems. It has been more than 10 years since the first computer system was introduced in the domestic medical area. We have been trying to build more advance and more friendly computer systems. Recent advances of information technology could make this possible. In this paper, I introduce the system design of Integrated Hospital Information System include core technology, components of the system and important factors to be considered.

The purpose of this study is to provide a basic data by evaluation the problems about nursing information system and identifying the need of improvement of it. Data were collected from April 6 to 15, 2000 through questionnaires taken by 218 nurses working in a general hospital using nursing information systems. The two structured questionnaires were used for the collecting the data. The data obtained were analyzed by using frequency, percentage, mean, standard deviation, t-test, one-way ANOVA, Pearson's correlation coefficients, and Cronbach's alpha coeffcients. The results are as follows: 1. In the problem of nursing information system, ${\lceil}$There are no appropriate programs for independent nursing information systems because there are no nurse informatists in the information department${\rfloor}$ scored highest. Also, ${\lceil}$There is a lack of manual for operation of the nursing information system${\rfloor}$, ${\lceil}$There is difficulty getting help when the system is in trouble${\rfloor}$, ${\lceil}$General information about using computers and managing problems are lacking${\rfloor}$, ${\lceil}$Unsatisfactory matters about the nursing information systems are not improved quickly.${\rfloor}$ received high scores. 2. In the need for improvement of the nursing information system, ${\lceil}$Nursing education and research${\rfloor}$ was the highest area of the system. 3. The problems of the nursing information system showed high positive correlation with the need for improvement of the system(p=.00).

Medical errors such as adverse drug event, improper transfusion, wrong-site surgery, mistaken patient identity and so on commonly occur at health care practice. Information technology, like Drug Utilization Review(DUR) system which reviews, analyzes, and interprets medication data when prescribing, can play a key role in reducing such medical errors and improving patient safety. Korean Government has guided all hospitals to implement concurrent DUR(cDUR) system, which is the first case worldwide in that all healthcare providers have to use cDUR system when prescribing. This paper introduced a case study that a tertiary hospital has integrated the cDUR system into its comprehensive Hospital Information System(HIS) and analyzed the whole prescription data during a week right after adoption of cDUR system. Considering technical strength and weakness, the cDUR system was integrated into the HIS, using Broker Servers for minimizing doctors' anxiety. As the quantitative analysis of the whole prescription data, DUR conflict events, which mainly included duplicate medications and contra-indicated drug interactions for outpatients, were 2.77%. Although only 0.7% is for the contra-indicated drug interactions, it will be greatly devoted to achieve the purpose of DUR such as improving patient safety.

Due to the rapid socioeconomic development and the introduction of the national health insurance system the general population's need for health care and utilization of health care services have increased dramatically. As a result of this change. Korea is experiencing a shortage of health care facilities and health manpower, and this leads long wailing line at doctor's offices. One of the solutions of this problem could be home health care system for those who have minor health related problems. With this background, this study was conducted to look at the feasibility of a home-based prenatal care system using information superhighway and nursing informatics specialists. With the home-based prenatal care system, the pregnant woman checks her blood pressure, tests her urine for sugar and protein, and measures her body weight at home and sends the information to a hospital computer via the information networks such as public telephone line and information superhighway. Nursing informatics specialist at the hospital will go through each patient record and screen those who have abnormal values and notify them to see a doctor as soon as possible. Besides telemonitoring features, the proposed system will include tole-education capabilities for the patients so that patient can learn whatever they need to know ragarding the prenatal care via information networks. If this system develops and operates, patient can save time in terms of travel to and from the hospital and waiting time in the hospital. And the health care institute can utilize its resource more efficiently.

During hospital peak times of outpatients, an effective mechanism that informs the newly receipted patient information to corresponding medical departments is lacking in current hospital reception systems. Since every department repeatedly searches entire patient reception database in sequential manner to acquire its reception information, this is a significant performance degradation factor in hospital information system. To improve hospital reception system efficiency, we developed two web socket based systems, a primary key transmitting batch system and a reception information transmitting real time system. The former reduced database access time compared to sequential search system as well as kept search time low regardless of receipted patient number. The latter effectively reduced waiting list updating time in request/response patient reception system by eliminating database access.

The purpose of this study is to analyze the mediating effect of informatization level between characteristics of introducing information system and organizational performance in hospital settings, and to provide suggestions to improve the performance level of strategic information system of hospitals. In order to achieve study purpose, a causal path model was developed and empirically tested. Data were collected from 746 managers of 92 hospitals keeping information system in Busan, Ulsan and Kyungnam Province using self-administered structured questionnaire. Major results of this study were as follows; The results of the path analysis showed that organizational characteristics variables except informatization strength within health industry had significant effects on informatization level, and had indirect effects on organizational performance mediated by informatization level. On the other hand, informatization level, especially revelation capability among informatization level variables, was found to have significant direct effect on organizational performance. These results of empirical test imply that informatization level variables are both important affecting factors on organizational performance and mediating factors between organizational characteristics and organizational performance. Therefore, in order to increase organizational performance, measures improving informatization level should be developed and carried out continuously. And, especially, focusing on building and strengthening revelation capability is crucial to those efforts.
