- 医疗保健管理的管理
- 运营研究 运营研究
- 公共卫生 公共卫生
背景情况:
- 紧急部门 (ED) 的拥挤对患者的安全和护理效率产生了负面影响.
- 年平均 (AA) 占用率方法是常用的,但未能考虑短期波动,导致不准确的容量评估.
- 精确估计ED床位需求对于有效的资源分配至关重要.
研究的目的:
- 为了比较六种估计急诊室床位需求的方法.
- 评估每小时峰值床位占用率 (HPBO) 作为年度平均 (AA) 方法的优越替代方案.
- 确定一个实用和准确的方法来确定最佳的ED床位容量.
主要方法:
- 来自韩国的国家紧急情况部门信息系统 (NEDIS) 数据库的分析 (2022年有408个ED,7,678,743次住院).
- 五种方法 (AA,月均值,日均值,每日峰值床位占用率,HPBO) 与实时占用率 (RTO) 黄金标准的比较.
- RTO将床位短缺定义为占用率>100%,占用时间>20%.
主要成果:
- 9.1%的EDs (37/408) 经历了基于RTO方法的床位短缺.
- 据HPBO估计,短缺ED所需的平均9张额外床位 (IQR5-16),与RTO的7张床位 (IQR3-14) 非常接近.
- 该AA方法低估了7个ED的床位需求,估计中位数为7个床位 (IQR 1-14).

Methods of Documentation VI: Case Management Model
844
The case management model is a multidisciplinary approach that involves healthcare professionals from diverse disciplines, such as physicians, nurses, therapists, social workers, and pharmacists, working collaboratively to address the various needs of patients. Each healthcare professional brings unique expertise and perspectives, contributing to a more comprehensive understanding of the patient's condition and tailoring treatment plans accordingly.
For example, a patient with a chronic...

Methods of Documentation V: CBE
1.4K
Charting by Exception, or CBE, is a method of documentation used in healthcare, particularly in nursing, that focuses on documenting only significant or abnormal findings rather than recording every detail. This approach aims to streamline the documentation process, improve efficiency, and ensure that healthcare providers can quickly identify deviations from normalcy in patient assessments.
In CBE, healthcare professionals establish predefined standards of practice that define what constitutes...

Statistical Methods for Analyzing Epidemiological Data
888
Epidemiological data primarily involves information on specific populations' occurrence, distribution, and determinants of health and diseases. This data is crucial for understanding disease patterns and impacts, aiding public health decision-making and disease prevention strategies. The analysis of epidemiological data employs various statistical methods to interpret health-related data effectively. Here are some commonly used methods:

Interpreting Run Charts
3.0K
Run charts, essentially line graphs plotted over time, serve as fundamental yet effective tools for process analysis. They chronicle data sequentially, facilitating the identification of trends, shifts, or cyclical movements. This graphical representation is instrumental in determining whether a process is stable or exhibits signs of potential instability indicative of special cause variation. In the healthcare domain, run charts depict infection rates over time, enabling hospitals to monitor...

Planning Nursing Care I
5.5K
The planning phase of the nursing process helps nurses set priorities, outline patient-centered goals and expected outcomes, and tailor nursing interventions to align with the aligned care plan. Through the planning phase, the nurse applies critical thinking skills to align and develop interventions according to the patient's needs. It provides continuity of care allowing patients to receive the maximum benefit from treatment. It serves as a pilot plan for allocating individual staff to a...
