Nursing staffing is of major interest in hospital management, however, no practical method has been developed. The present study proposed a mathematical model based on the patient classification system for nursing staffing optimization. A few characteristic parameters possibly determined experimentally and/or empirically were introduced followed by systematic calculation of the required number of nurses. An essential concept of the model is the unit work load defined as the amount of nursing work performed on single patient per unit time, where the work load is defined as the number of nursing staffs multiplied by the working hours. The unit work load was considered to vary with the patient classification level as well as the working time during a day, both of which were represented by corresponding parameter values. The number of patients for each class and the number of working hours were multiplied to the unit work load, and added up to obtain the total required work load. As the next step, the averaged number of hours that a nurse could provide per day was formulated considering the degree of nursing practice experience into 3 levels. Finally, the appropriate number of nursing staffs was calculated as the total work load divided by the average working hours per nurse. The present technique has a great advantage that the number of nursing staffs to fulfill the required work load is systematically calculated once the characteristic parameters are appropriately determined, leading to instant and fast evaluation. A practical PC program was also developed to apply the present model to nursing practice.

This study was conducted to identify the effectiveness of meridian acupressure for enhancement of post operative bowel movement to the patient with absolute bed rest who having surgery under general anesthesia. This study used a qusai experimental, nonequivalent control group post test only design. This subject were 44 patients, 22 for the experimental and 22 for the control group, who were admitted at KyungHee University hospital, neurosurgical unit A and B ward, assigned by matched sample by the name of operation who having microvascular decompression and laminectomy. Date were collected from May 1, 2001 to June 30, 2001 by auscultation, self report and by using 7 point face scale. The recovery of bowel sound were measured every 4 hours until gas out for 1 minute auscultation on lower abdomen after 4 hours having surgery. The time of gas out were measured by self report, the severity of nausea were measured every 4 hours for 7 point face scale and also the degree of satisfaction of nursing care were measured after 2 days having surgery with same scale. Data were analyzed with $X^2$, t-test, repeated measures ANOVA and ANOVA. The result of this study were as follows; 1. The experimental group which were implemented with meridian acupressure showed shorter time the recovery of bowel sound after having surgery than control group(t=-5.112, p=.0001). 2. The experimental group which were implemented with meridian acupressure showed shorter time of gas after having surgery than control group(t=-4.010, p=.0001) 3. The experimental group which were implemented with meridian acupressure showed decreased level of nausea score according to time interval than control group(F=21.995, p=.0001). 4. The experimental group which were implemented with meridian acupressure showed higher the degree of satisfaction of nursing care than control group(t=-4.010, p=.0001). These finding indicate that a meridian acupressure could be a effective nursing intervention for enhancement of post operative bowel movement to the patient with absolute bed rest who having surgery under general anesthesia.

Recognition of the usefulness and the importance of the nursing diagnosis is increasing. There is a prevailing opinion that nursing diagnosis should be used to improve the quality of nursing care. Developing standardized nursing care palns based on nursing diagnoses is therefore considered one of the most essential projects for professional growth and improvement in the nursing world of Korea. Consequently, in the first stage of this research project, the ten nursing diagnses used most frequently with patients on medical and surgical wards were determined and related nursing care plans were developed, implemented and evaluated. The application of the standardized nursing care plans raised the nurses' confidence and proved to be effective in enhancing the quality of nursing care. This study was initiated as the next stage, to develop, test, and determine the validity of nursing care plans for the remaining nursing diagnoses. Nineteen medical and surgical wards were selected for the study ; the 176 staff nurses working on those wards and 1211 patients hospitalized there (603 patients during the nursing care plan use) took part in the project. The following summarizes the results of the study : 1. After listing all the nursing diagnoses up to the 20th in frequency from each ward except the ten used in the first study, 22 nursing diagnoses were selected. Two related to ‘self care deficit’, were combined into one. Standardized nursing care plans were established for these 21 nursing diagnoses. 2. The first page of each nursing care plan lists the related factors and defining characteristics as supporting data. The application rate distribution revealed that the majority were recorded less than 50% of the time. For each nursing diagnosis, only one to three related factors were recorded more than 50% of the time regardless of the number of suggested related factors, and similarly, only one to five defining characteristics were recorded more than 50% of the time regardless of the number of suggested defining characteristics. Therefore, these factors and defining characteristics were proposed as the common related factors and the typical signs and symptoms for each nursing diagnosis. 3. The application rate distribution for the expected outcomes, and the nursing orders that were the main data of each nursing care plan occurred more than 50% of the time, unlike the related factors and the characteristics that occurred less frequently. These findings supported the clinical validity. 4. In an effort to evaluate indirectly the effect of the use of the standardized nursing care plans, nurses' job satisfaction and perceptions of their ability in the use of the nursing process were measured and compared. Scores after the use of the plans were significantly higher than those before. The experience in actually using the standardized nursing care plans with patients increased the nurses' professional and emotional satisfaction and their confidence in using the nursing process. Also when the nurses who actually used the nursing care plans were asked to rate their effectiveness, the highest score was given to ‘the ease of establishing the nursing goal’, followed by ‘improved professional advice and care for patients’, ‘the efficiency and systemization of charting’, ‘the definite recognition of the nursing problem’, and ‘the selection of effective and appropriate nursing interventions’ in descending order. The results indicate the nurses were very positive about the effect of the real clinical application of standardized nursing care plans, and that the objective of this study to utilize the nursing diagnosis to strengthen the nursing process was attained.

Purpose: The purpose of this study was to develop a Korean Adult Patients Delirium Screening Tool (K-APDS) for those admitted to general wards, and to verify its reliability and validity. Methods: For the development of the tool, 12 items were derived through the results of literature review and focus group interviews with general ward nurses, and the content validity was confirmed by experts. To verify the reliability and validity of the developed tool, 317 adult patients who were admitted to general wards of three tertiary general hospitals from October to November 2022 were evaluated by the attending nurse and data were collected. Results: After factor analysis for construct validity verification, two factors were extracted, which explained 60.1% of the total variance. After the validation of the control group, the difference in the delirium incidence scores calculated using the K-APDS between the delirium group and non-delirium group was very significant (Z=-10.82, p<.001). To verify the criterion validity, K-APDS, Delirium Observation Screening, and Pearson's correlation coefficient were checked and found to be .94 (p<.001). The predictive validity test reported that the sensitivity was 91.1%, specificity was 82.4%, positive predictive value was 52.6%, and negative predictive value was 97.8%. The reliability of K-APDS was found to be high with Cronbach's ⍺=.91. Conclusion: K-APDS can screen for delirium with 2 or more points, excellent validity and reliability have been verified. Therefore, this tool could be applied immediately in the clinical field, and will contribute to the early detection of delirium, enabling rapid interventions.

Purpose: This study aimed to examine the adequacy of current nurse staffing levels by identifying nursing activities and workload. Methods: The study used a mixed-method design. A nursing activity survey was conducted using the work sampling method over 2 working days with 119 general ward nurses. A focus group interview was conducted with 12 nurses. Quantitative and qualitative data were analyzed using SPSS 20.0 and content analysis, respectively. Results: The most amount of time was spent on medication (in direct nursing) and electronic medical record documentation (in indirect nursing). The appropriate nurse-to-patient ratio is 1:7.7 for the day shift, 1:9.0 for the evening shift, and 1:11.9 for the night shift. However, the current nurse-to-patient ratio is 1:9.4, 1:11.0, and 1:13.8 for the day, evening, and night shifts, respectively. Therefore, the current nurse staffing level is insufficient for the workload. In the focus group interview, the main reasons cited for being unable to complete tasks within working hours were communication and coordination, and the nursing electronic medical record. The essential nursing activities of basic nursing and emotional support were overlooked owing to a heavy workload. Therefore, an adequate nurse staffing level should be higher than the measured quantitative workload. Conclusion: These results suggest the general wards of tertiary hospitals should evaluate the adequacy of their current nurse staffing and allocate sufficient nurses to improve patient safety and nursing care quality.

칸디다혈증(candidemia)은 이환율과 사망률을 높이는 주요 원인으로 입원 환자에서 심각한 위험으로 남아 있으며 의료비용을 증가시킨다. 2009년부터 2018년까지 S병원의 혈액배양 검사에서 분리된 칸디다 균주 3,533건을 대상으로 시기별 분리빈도, 연도, 성별, 나이, 병동 등에 따라 분석하였다. 전체 기간 중 혈액 배양 의뢰 건수 717,996 중에 54,739건이 배양 양성으로 7.6%의 양성율을 보였으며 칸디다 분리률은 1,036명의 환자에서 3,533건으로 6.4%였다. 균종의 분포는 C. albicans (33.8%), C. tropicalis (28.6%), C. glabrata (19.8%), C. parapsilosis (7.8%), C. krusei (4.0%) 이다. 전기/후기 분리에서는 C. tropicalis가 3.8% 감소하고 C. glabrata는 3.4% 증가하였다. 50세 이후 연령이 증가할수록 분리 빈도가 높았으며, 1~10대에서는 C. parapsilosis (31.3%), 41~50대에서는 C. tropicalis (30.3%), C. glabrata (27.6%) 순으로, 80대에서는 C. tropicalis (28.6%)가 상대적으로 자주 분리되었다. C. krusei 는 여성(60.9%)에서 상대적으로 높은 비율로 분리되었다. 따라서 Candida 균종의 분포를 지속적으로 감시하고 신속한 동정 결과를 제공하여 적절한 치료 및 항진균제 치료 지침을 위한 체계적이고 지속적인 병원감염관리 시스템이 이루어져야 할 것이다.
