概括
在选择新的部或膝盖假肢时,骨科医生优先考虑临床证据和产品质量. 离散选择实验 (DCE) 与最佳-最差缩放 (BWS) 相比,更好地揭示了医生对医疗器械的真正偏好.
科学领域:
- 卫生经济学 卫生经济学
- 医疗器械评估 医疗器械评估
- 整形外科手术 整形外科手术
背景情况:
- 医生优先项目 (PPI) 是高成本的医疗器械,临床选择对采购产生重大影响.
- 了解医生偏好对于优化选择关节和膝关节假肢等骨科植入物至关重要.
- 偏好诱导方法中的响应偏差可能会扭曲结果,需要强大的评估技术.
研究的目的:
- 确定影响骨科医生选择新关节或膝关节假肢 (PPI) 的关键因素.
- 为了比较两种声明偏好技术的有效性:最佳-最差缩放 (BWS) 和离散选择实验 (DCE).
- 调查PPI选择方法中的潜在响应偏差.
主要方法:
- 一项在线调查对108名意大利骨科医生进行了调查.
- 采用了两种方法:第一类最佳-最差缩放 (BWS) 和二进制离散选择实验 (DCE).
- 用条件逻辑和混合逻辑回归模型分析数据,包括支付意愿 (WTP) 估计.
主要成果:
- BWS表示"临床证据"和"产品质量"最重要",销售代表关系"和"成本"最不重要.
- DCE显示,他们更喜欢具有强有力的临床证据,积极的HTA,负担得起的成本和确定的使用/关系的高质量产品.
- 在BWS和DCE方法之间,整形外科医生表示的偏好差异很大.
结论:
- 不同的偏好诱导方法对医生偏好项目 (PPI) 产生不同的结果.
- 1型BWS可能容易受到默许和社会可取性偏见的影响.
- 通过结合复杂的权衡,离散选择实验 (DCE) 更有可能捕捉医生对医疗器械的真正偏好,减轻反应偏差.

Blind Procedures
Ideally, the people who observe and record the children’s behavior are unaware of who was assigned to the experimental or control group, in order to control for experimenter bias. Experimenter bias refers to the possibility that a researcher’s expectations might skew the results of the study. Remember, conducting an experiment requires a lot of planning, and the people involved in the research project have a vested interest in supporting their hypotheses. If the observers knew which child was...
Data Collection III
The physical assessment examines the patient for objective data that defines the patient's condition, and aids in formulating the nursing care plan. The purpose of physical assessment is a health status appraisal, which includes identifying health problems, and establishing a database for nursing intervention.
The principles to begin the physical assessment include conducting a comprehensive or problem-related history in a quiet, well-lit room, emphasizing privacy and comfort for the patient.

Methods of Documentation III: PIE
Problem-intervention-evaluation (PIE) is a systematic approach to documentation used in healthcare settings for clinical decision-making and patient care planning. It is a structured approach to organizing patient data based on problems, interventions, and evaluations. Here's a breakdown of its key features and considerations:
