  • A hospital's intensive care unit (ICU) is a limited and critical resource whose efficient utilization of capacity impacts on both the welfare of patients and the hospital's cost effectiveness. Decisions made in the ICU affect the operations of other departments. Yet, decision making in an ICU tends to be mainly subjective and lacking in clear criteria upon which to base any given decision. The study reviews the capacity utilization of one particular ICU, that of a public hospital in Hong Kong, and develops a computer simulation model to improve both the unit's capacity utilization and the quality of care provided to its patients.

  • This study analyzes the effects of hospital caseload on medical charges and length of stay for inpatients. Hospital caseload, representing the level of concentration of patients, was measured with the Internal Herfindal Index for three diagnosis related group (DRG) codes (appendectomy, operations on anus, and operations on uterus and adnexa). Ordinary least squares regression was used for analysis. Results showed that medical charges per inpatient and average length of stay significantly differed with respect to hospital concentration indices, and that hospital caseload was inversely related to operational performance for appendectomy and operations on uterus and adnexa. The significant negative relationship between concentration index and length of stay may decrease the total medical charges. The results imply that the expansion of the DRG payment system to hospitals will have a negative influence on their gross sales.

  • The purpose of this study is to investigate the overall operations of National Hospital Food service after it was benefited by National Health Insurance (NHI). The survey was conducted between July and August, 2007. Among questionnaires mailed to 2,558 medical care institutions, 2,090 returned (81%) questionnaires were analyzed by descriptive statistics, $x^2$-test and ANOVA using the SPSS 13.0. The general foodservice characteristic of medical care institutions were as follows. The type of foodservice operations were 'self-operated' (86.9%), 'contracted' (10.5%) and 'Both' (2.6%). Only 6.4% of medical care institutions provided 'hospital food menu not benefited by NHI'. The number of dietitians and cook for medical care institutions were 1.1 and 1.0, respectively. The cost of a general diet meal was 4,205 won and therapeutic diet meal was 4,434 won. The overall operations of hospital foodservice were different depending on the types of medical care institution. After hospital foodservice was benefited by NHI, the overall quality of hospital foodservice including manpower, facilities, and environment was improved. The future direction of hospital foodservice should 1) differentiate the cost of hospital foodservice by the types of medical care institution, 2) increase in co-payment, and 3) provide same service with equal expenses in each party as medical aid or NHS beneficiary.

  • 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.

  • Purpose: The purpose of this study is to examine the changes of surgical patients' body temperature in applying warming to patients. The study of an effective nursing intervention, which aims to prevent hypothermia during surgical operations, use of anesthesia, and to remove dermal discomforts. The nonequivalent control group pre-test/post-test design was used for this quasi-experimental study. Method: The study subjects were adult patients who would take a surgical operation under general anesthesia in C Hospital; the surgical operations done were, total abdominal hysterectomy or Myomectomy; 20 patients were included in experimental group I, 20 patients were included in experimental group II, and 20 patients were in the comparative group. The total number of study subjects was 60. The data was collected from September the 1st, 2001 to October the 20th, 2001. The data was analyzed by SPSS program, F-test and Repeated measures of ANOVA. Multi-comparison method of DUNCAN was used for the sections that show the significant differences at the level of p<.05, which was a posterior examination. Result: 1) "The body temperatures of the three groups of patients will be respectively different at the end of the operations; experimental group I to which warming was applied before the operations, experimental group II to which warming was applied during the operations, and the comparative group with no warming being given," showed (F=12.609, p=.000). 2) "Degrees of shivering symptoms for the three groups will be respectively different at the end of the operations; experimental group I which applied warming before operations, experimental group II which applied warming during operations and the comparative group with no warming." Showed assumed (F=6.626, p=.000). Conclusion: Summing up the above study, the warming assumed during operations was a more effective nursing intervention for preventing patients' hypothermia than the warming assumed before operations.

  • Objective: To compare the efficacy of anal preserving surgery for aged people with low rectal carcinoma. Methods: Clinical data for a consecutive cohort of 98 rectal cancer patients with distal tumors located within 3cm -7cm of the anal verge were collected. Among these, 42 received anal preserving surgery (35 with Dixon, 3 with Parks and 4 with transanal operations). The local recurrence and survival rates in the above operations were compared with those of the Miles operation in another 56 patients with rectal cancer. Results: The local recurrence and 3-, 5-year survival rates of anal preserving surgery were 16.7%, 64.3% and 52.4%, those of Miles operations were 16.1%, 67.9% and 51.8% respectively (P>0.05). Conclusion: Anal preserving surgery for aged people with low rectal cancer is not inferior to conventional operations in China, with satisfactory long term survival and comparable local recurrence rates.

  • Brown syndrome is known as limited elevation of the affected eye during adduction. It is caused by a disorder of the superior oblique tendon, which makes it difficult for the eyeball to look upward, especially during adduction. It is classified into congenital true sheath Brown syndrome and acquired simulated Brown syndrome. Acquired simulated Brown syndrome can be caused by trauma, infection, or inflammatory conditions. The surgical restoration of blowout fractures can also lead to limitations of ocular motility, including Brown syndrome. We report on three patients with acquired simulated Brown syndrome, who complained of diplopia and limitation of ocular motility after operations to treat blowout fractures.

  • The aim of our study is to determine maximum surgical blood order schedule (MSBOS) in each surgical operation through analyzing usage of blood products at Bundang Jesaeng General Hospital. We investigated the amount of transfused red cells for each operation and calculated crossmatching-to-transfusion ratio (C/T ratio) and MSBOS. This was accomplished by referring to the Laboratory Information System program during 1 year from January through December 2003. Coronary artery bypass surgery and decompressive craniectomy showed the highest MSBOS in our hospital. The average C/T ratio was 3.2 and excessive reservations for blood products have been made for many operations. From this study, guidelines for the optimal blood ordering for each surgery were suggested.

  • This paper deals with the application of Supply Chain Operations Reference (SCOR) model to make a Service Supply Chain(sSC) of a hospital treatment service. At first, we compare the service supply chain with the traditional supply chain. At second, we apply the SCOR model to a service supply chain of a hospital treatment service and make new process of the hospital service supply chain if we need it. Finally, we explain the applied results and propose the improvement points. The used level of SCOR model is from level 1 to level 3.
