Tertiary been increasing rapidly. There has been shortage of beds in hospitals and effective management of beds had to b considered. For the efficient utilization of the exsisting hospital beds, bed turnover rate ha to be high and their length of stay in hospital has to be shortened. The sample of this study was in-patients admitted in 13 clinical departments of a tertiar hospital in Wonju. Daily medical fees through length of stay in hospital were observed an we analyzed the increase of hospital revenues per bed for the shortening of length of stay. The results of the analysis were as follows: 1. The average length of stay by dept. was 11.0 in dept. of internal medicine. 12.4 in dept. of general surgery, 7.1 in dept. of gynecoloty, 6.8 in dept. of pediatrics, 26.1 in dept. of nervous surgery, 21.6 in dept. of orthopedic surgery, 25.5 in dept. of plastic sersury, 7.6 in dept. of ophthalmology, 7.1 in dept. of E.N.T, 8.1 in dept. dermatoloty, 9.0 in dept. urology. 2. The trend of daily medical fees of in-patients was the highest from the first day to the third day. Because most necessary examination and various treatment or operation took place in these period. 3. The estimative model for medical fees by the length of stay at each clinical department was inferred. 4. The increased revenue per bed by shortening the length of stay was calculated by the estimative model. Shortening one day would increase 305,999 thousand won in dept. of internal medicine 232,138 thousand won in dept. of general surgery., 177,795 thousand won in dept. of gynecology medicine, 69,031 thousand won in dept. of pediatrics 360,381 thousand won in dept. of nervous surgery 211.339 thousand won in dept. of orthopedic surgery, 100,249 thousand won in dept of plastic surgery, 10,569 thousand won in dept. of ophthalmology -814,122 thousand won in dept. of E.N.T, 1,582 thousand won in dept. of dermatology, -5,821 thousand won in dept. of urology. It is expected that they can improve their profitability by shortening the length of stay of the in-patients.

본 연구에서 개발된 의료용 침대는 N개의 건반으로 이루어져 각각이 엑츄에이터에 의해 수직으로 구동된다. 각 건반에는 M개의 센서가 실장되어 체압을 측정하므로 체압지도의 해상도는 MN에 의해 결정된다. 각 건반에는 센서 제어기가 실장되어 M개의 센서로부터 측정한 체압값을 CAN(Car Area Network)와 같은 직렬 통신 네트워크를 통해 메인제어기로 전달한다. 각 건반에는 모터를 구동하는 서보 드라이버가 하나씩 장착되며 메인 제어기와 CAN으로 연결되어 메인 제어기에서 지시된 변위값대로 건반의 높낮이를 제어하며 향후 개발될 인공지능 제어 알고리즘을 위해 신체 각부의 편안도를 조사하여 건반의 높낮이를 맞추었다. 또한, 건반 각부에 걸리는 최대 체압값과 체압비를 계산하여 인공지능에 의한 침대 편안도 제어를 위해 기초 데이터로 활용한다. 결과적으로 제시된 시스템은 향후 개발될 인공지능에 의한 신체의 안락함과 욕창 방지 제어를 위해 활용될 수 있는 토대가 될 수 있다.

A major accident occurring on the bed is falls that occur during at times when the care of nurses or protectors is inadequate, which is fatal to patients or the elderly. In particular, Enuresis or sleepiness caused by sleep apnea increases the risk of falls. Therefore, it is very important to detect falls and sleep apnea of patients without infringing privacy in the bed to patient's safety and accident prevention. In this paper, we reviewed the technologies developed for bed monitoring and implemented a non-intrusive monitoring system. The Occupancy Sensor allows the temperature of the bed and surrounding area to be extracted to enable track of the patient's motion. The Doppler Radar detects the patient's movements at normal times and the respiration state when patients have no movement during sleeping. It is specially designed for real-time monitoring of falling and respiration during sleeping through contactless multi-sensing while solving patient's privacy problems.

Objective : The aim of this study is to implement a critical pathway (CP) for patients undergoing lumbar laminectomy or microdiscectomy and describe the results before and after the CP in terms of length of hospital stay and cost. Methods : From March 2008 to February 2009, 61 patients underwent lumbar laminectomy or microdiscectomy due to stenosis or one- or two-level disc herniation in our department and were included in the prepathway group. After development and implementation of the CP in March 2009, 58 patients were applicable for the CP, and these were classified as the postpathway group. Results : The CP, which established a 6-day hospital stay (5 bed-days), was fulfilled by 42 patients (72.4%) in the postpathway group. The mean length of stay was 5.4 days in the postpathway group compared to 6.9 days in the prepathway group, demonstrating a 20% reduction, which was a statistically significant difference ($p{\leq}0.000$). There was a statistically significant reduction in charges for bed and nursing care (p=0.002). Conclusion : Implementation of a CP for lumbar laminectomy or microdiscectomy produced significant decreases in length of hospitalization and charges for bed and nursing care. We believe that this CP reduces the unnecessary use of hospital resources without increasing risk of adverse events.
