This study purported to evaluate the performance of the appointment system for outpatients in primary care dental clinic. The data of patients' time flow for 1,245 patients in Y Dental Clinic were collected for one month in 2002 and then analyzed. Specifically, the time periods of treatment and patients' waiting as well as rates of appointment and it's failure are estimated. The accuracy of expected treatment time period was also evaluated. The results showed that 72% of patients visited the clinic with appointments, and only 56% kept their appointments. The patient's waiting time period turned out to be 11 minutes in Y clinic. The expected treatment time period is turned out to be very important because they influence significantly on patient's waiting time period. Practically, the expected treatment time period should be overestimated about 9 minutes in general, and the characteristics of dentist, each patient's diagnosis and age need to be especially considered. Hospitals and clinics also need to make the systematic and detailed critical pathways for a variety of patient cases by analyzing the patients' treatment pattern. With the improved appointment systems, healthcare institutions will approach the goal of effective and efficient management of the institution and also satisfy their customers.

The purpose of this study was to determine the level of appropriateness in hospital stays and factors influencing inappropriate hospital stays. The study was conducted at fifteen general care units in a tertiary university hospital. Appropriateness of hospital stay was assessed using Appropriateness Evaluation Protocol by trained head nurses. The total of 447 patient records were reviewed. Among them, 352 patient data were included in the final data set. A unit of observation was patient day. A rate of appropriate hospital stay was calculated per patient as a unit of analysis. Multiple regression analysis was performed to determine the factors affecting inappropriate hospital stay. The eighty-three percent (2030/2651) of hospital stays were evaluated as appropriate. There were significant differences in appropriateness of hospital stay according to patient's age, type of health insurance, medical specialty, and length of stay(p<0.05). In the multiple regression analysis, medical speciality was the most significant factor to predict the inappropriate hospital stay. The study showed a substantial proportion of hospital stay was found to inappropriate. Level of appropriateness was significantly different from medical specialty. Interdepartmental approach should be required to coordinate and improve appropriate resource utilization.

Public healthcare has recently become an issue of great importance due to the exponential growth in the human population, the increase in medical expenses, and the COVID-19 pandemic. Speed is one of the crucial factors in saving life, particularly in case of heart attack. Therefore, a healthcare device is needed to continuously monitor and follow up heart health conditions remotely without the need for the patient to attend a medical center. Therefore, this paper proposes a portable electrocardiogram (ECG) monitoring system to improve healthcare for heart attack patients in both home and ambulance settings. The proposed system receives the ECG signals of the patient and sends the ECG values to a MySQL database on the IoT-cloud via Wi-Fi. The signals are displayed as an ECG data chart on a webpage that can be accessed by the patient's doctor based on the HTTP protocol that is employed in the IoT-cloud. The proposed system detects the ECG data of the patient to calculate the total number of heartbeats, number of normal heartbeats, and the number of abnormal heartbeats, which can help the doctor to evaluate the health status of the patient and decide on a suitable medical intervention. This system therefore has the potential to save time and life, but also cost. This paper highlights the five main advantages of the proposed ECG monitoring system and makes some recommendations to develop the system further.

Purpose: Korean medical services are not balanced across regions and social classes. To prevent mortality gaps, Korea must distribute its medical resources more efficiently. Patient factors affecting emergency room visits serve as basic data for determining best practices for public healthcare distribution. Methods: The data included 18 473 visits by 14 949 de-identified patients who visited a public emergency room over one year. The dependent variable was the number of emergency room visits. A Poisson regression was conducted with the independent variables, comprising sociodemographic, socioeconomic, and spatial accessibility factors and patient characteristics. Results: Older men with higher Korean Triage and Acuity Scale scores visited more frequently. Greater patient-hospital distance decreased visits; however, the presence of a hospital within 1 km of a patient's residence did not affect the number of visits. The use of 119 services was negatively correlated with the number of visits. Visits increased with more medical benefits. Conclusions: Patient age, distance to hospital, use of 119 services, and medical benefits should be considered when planning or managing public hospitals in Korea.

This study aims for examines the actual physical symptom and stress in caregivers of patients with cerebrovascular disease. The data were collected by a survey conducted from August to September, 1997 which included 65 caregivers of cerebrovascular disease patients in 4 hospitals located in Seoul. The caregiver's stress was measured by Choi (1992)'s instrument and the actual physical symptoms were investigated. The data were analyzed using ANOVA, Scheffe test, Pearson correlation coefficient and stepwise multiple regression. The results were as follows : 1. The mean number of caregiver's physical symptom was 3.5. There were significantly higher number of physical symptom in women, those of who have a religious affiliation, those of who perceive their own health status perceived as bad, and those of who perceived their patients disease condition as serious than in their counterparts. Also, the number of caregiver's physical symptom was significantly higher in caregivers whose patients have a paralysis sypmtom and the disease onset as accident than in caregivers whose patients have no paralysis symptom and the disease onset as spontaneous. 2. The average of caregiver's stress was 57.9. The caregiver's stress was the highest in between the ages of 50 and 59. There were also significantly higher level of stress in women, those of who perceived the disease condition of their patients as serious than in their counterparts. 3. The most common caregiver's physical symptom was fatigue(87.7%). This was followed by insomnia(58.5%) and muscle pain(47.7%). 4. Caregiver's physical sypmtom was positively correlated with caregiver's stress and negatively correlated with patient's activity of daily life. 5. The most important vairable affecting the caregiver's physical symtom was patient's activity of daily life which accounted for 12.7% of the total variance in stepwise multiple regression analysis. The most important vairable affecting the caregiver's stress was the patient disease condition perceived by the caregiver that accounted for 12.1% of the total variance.

The purpose of this study is to identify the nature of the patient service quality of health center, and based on that, to examine the relationship of health center visitor's perceived quality and overall satisfaction. Data were collected on the basis of 'the 3rd Regional Health Care Planning' operated by Rural Health Care Service Technology Aid Task-force Team(RHCSTAT), Ministry of Health and Welfare. Basically, the Manual of 3rd Regional Health Care Planning is composed of structure, process, and outcome measurement indicators. Of these indicators, 21 patient satisfaction questions as outcome indicators are used in this study. The samples are 3,530 patients who visited 80 health centers all of the nation. First, the reliability and validity of patient service quality items was evaluated. Second, the descriptive statistics of health service quality are calculated. Third, through the T-test and ANOVA, the differences of patient satisfaction by responder's general characteristics are compared. In final, to explore the relationship of service quality and overall satisfaction, multiple regression analysis was used. This study shows firstly, the dimension of patient service quality was categorized into 3 dimensions, that is, facilities and environment, staff kindness, and access convenience. Secondly, the reliability and validity of patient service quality items was satisfied. Thirdly, the mean score of staff kindness factors are high in contrast to the facilities and environment. And in regard to the overall satisfaction, the mean score is more higher in Daegu region, County type health center, male group, and upper 65 age group than comparison groups. Lastly, as a result of multiple regression analysis, the effect of patient's perceived service quality, especially, appropriateness of billing time(Beta=0.190) and of reservation time(Beta=0.132) are statistically significant(P<0.01). In conclusion, to satisfy the health need of community people and improve the service quality of the health center, the efforts for the access convenience might be needed. Additionally, the enlargement on health center space and supply of new medical equipment is urgent for the patient satisfaction.

Digital technology is gradually expanding its field and has a great influence on various fields of dentistry. Recently in digital dentistry, the importance of superimposing various 3-dimensional (3D) image data is emerging, in order to utilize gathered data effectively for diagnosis and prosthesis fabrication. Integrating data from facial scans, intraoral scans, and mandibular movement recordings can create a virtual patient. A virtual patient is formed by integrating digital 3D diagnostic data such as intraoral and extraoral soft tissues, residual dentition, and dynamic occlusion, and the results of prosthetic treatment can be evaluated virtually. The patients in this case report were a 37-year-old female whose chief complaint is that the appearance of the existing prosthesis was distorted and a 55-year-old female patient whose anterior prosthesis needed to be refabricated after the endodontic treatment. 3D facial scans were obtained from each patient, and the patient's mandibular movements were recorded using ARCUS Digma 2 (KaVo Dental GmbH, Biberach an der Riss, Germany). The collected data were integrated on computer-aided design (CAD) software (Exocad dental CAD; exocad GmbH, Darmstadt, Germany) and transferred to a virtual articulator to create a digital virtual patient. The temporary fixed prostheses were designed, restored, and evaluated, and it was reflected into the final restorations. With the aid of the virtual dental patient, accuracy and predictability could be increased throughout treatment, simplifying the occlusal adjustment and clinical evaluation with improved esthetic outcomes.
