概括
国际疾病分类 (ICD) -10代码对于识别严重的孕产妇发病率的有效性不佳,这表明使用这些代码的研究可能存在偏见.
科学领域:
- 产科和妇科 产科和妇科
- 医疗保健服务研究 医疗服务研究
- 医疗信息学 医疗信息学
背景情况:
- 严重的孕产妇发病率 (SMM) 是产科并发症的关键指标.
- 使用国际疾病分类 (ICD) 代码的行政数据通常用于识别SMM.
- 之前的研究表明,与医疗记录相比,SMM的ICD代码的预测价值较低.
研究的目的:
- 评估ICD-10代码用于识别SMM的有效性.
- 为了比较ICD-10代码准确度与医疗记录抽象作为黄金标准.
主要方法:
- 一项对公立医院1000例分娩 (2016-2018) 的回顾性研究.
- 评估了SMM的ICD-10代码的敏感性,特异性,正预测值 (PPV) 和负预测值 (NPV).
- 医疗记录抽象作为病例识别的黄金标准.
主要成果:
- 67个SMM病例通过ICD-10代码确定;74个病例通过医疗记录.
- 灵敏度:26% (95% CI:16%-37%);PPV:28% (95% CI:18%-41%). 这是一个很大的问题.

Hospitals offer medical and surgical care to the sick and injured, along with accommodation while they recover. At the same time, they also provide outpatient, emergency, psychiatric, and rehabilitation services to meet various community needs. In addition to providing medical care, hospitals also act as hubs for medical research and training. Hospitals use clinical procedures and evidence-based practice standards to deliver patient care. To deliver safe and efficient care, a nurse must stay up...

Formulating and Validating Nursing Diagnosis II
2.8K
Nursing diagnoses represent a problem validated by major defining characteristics. There are four categories of nursing diagnoses: problem-focused, risk, health promotion or wellness, and syndrome. The anatomy of a nursing diagnosis includes three components: problem statement or diagnostic label, defining characteristics, and related factors.

Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.

Hospitals provide inpatient and outpatient services. Inpatient services provide care to patients that stay in the hospital for an extended period, ranging from days to months. Examples of inpatient services include intensive care units, hospital wards, or surgeries. Outpatient services provide care to patients who come to a hospital for a diagnostic or treatment but do not stay overnight —for example, diagnostic tests, surgical procedures, or health education.

Nursing Interventions II: Selecting and Classifying the Nursing Interventions
2.2K
Creating and executing a nursing diagnosis helps nurses plan care and guide patient, family, and community interventions. They are developed based on a patient's physical evaluation and support measuring the outcomes. It is not recommended to select random interventions throughout the planning process. Instead, consider the following six essential factors when choosing interventions:

Methods of Documentation V: CBE
900
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...
