概括
多种疾病治疗负担问卷 (MTBQ) 显示出良好的测试重试可靠性,并且在患有多种长期疾病的成年人中很容易完成. 逆转尺度并没有改善其心理测量特性.
科学领域:
- 医疗保健服务研究 医疗服务研究
- 心理测量 心理测量 心理测量
- 慢性疾病管理 慢性疾病管理
背景情况:
- 多病症,定义为存在三种或更多的长期疾病,影响了成年人口的很大一部分.
- 评估多病症患者所经历的治疗负担对于有效的医疗保健服务至关重要.
- 多病症治疗负担问卷 (MTBQ) 是一个旨在测量这种负担的工具,但需要进一步的心理测量验证.
研究的目的:
- 对多病症治疗负担问卷 (MTBQ) 进行进一步的心理测试.
- 评估反转MTBQ尺度是否会减少地板效应.
- 评估测试复试可靠性,并在英国初级保健环境中构建MTBQ的有效性.
主要方法:
- 采用了调查设计,从英国初级保健实践中招募了患有三种或以上长期疾病的成年人 (≥18岁).
- 参与者在基线和随访 (1-4周) 完成了MTBQ (原始和倒置尺度版本) 和治疗负担问卷 (TBQ).
- 从电子GP记录中提取了咨询和长期状况的数据. 分析了包括测试重试可靠性 (ICC) 和构造有效性 (斯皮尔曼等级相关性) 在内的心理测量属性.
主要成果:
- 244名成年人完成了基线调查,225人完成了随访. 逆转MTBQ尺度并没有减少地板效应或数据偏差.
- 该MTBQ证明了良好的测试重试可靠性 (ICC = 0.765).
- 全球MTBQ分数与全球TBQ分数 (Rs = 0.77) 有显著的相关性,与咨询 (Rs = 0.17) 和咨询的全科医生数量 (Rs = 0.23) 有微弱的相关性,但与长期疾病数量 (Rs = -0.063) 没有相关性. 据报道,这两份问卷都很容易填写.
结论:
- 多种疾病治疗负担问卷 (MTBQ) 显示出良好的测试重复测试可靠性,并且被多种慢性疾病患者容易填写.
- 这些发现支持在临床和研究环境中使用MTBQ来评估多病患者群体的治疗负担.
- 进一步验证,包括内容和内部一致性可靠性,建立在之前的研究基础上,加强MTBQ的实用性.

Methods of Documentation II: POMR
944
The Problem-Oriented Medical Record (POMR) revolutionized medical record-keeping by introducing a systematic approach focusing on the patient's problems rather than merely listing symptoms. Dr. Lawrence Weed's introduction of this method in the 1960s marked a significant advancement in medical documentation. The POMR framework consists of four key components: the database, problem list, plan of care, and progress notes.

Assessment of the Cardiovascular System I: Subjective Data
323
A thorough health history and physical assessment are essential for identifying cardiovascular disease (CVD) symptoms and distinguishing them from other health issues.
Initial Enquiry
Ask the patient about their primary concern and thoroughly explore all reported symptoms.
Medical History
Investigate past illnesses affecting the cardiovascular system, such as angina, anemia, rheumatic fever, congenital heart disease, stroke, thrombophlebitis, dysrhythmias, varicosities
