Responsibility loadings determine relative value units of dental services that translate services into a common scale of work effort. The aims of this paper were to elicit responsibility loadings for a subset of dental services and to relate responsibility loadings to ratings of importance of the components of responsibility.
Responsibility loadings and ratings of components of responsibility were collected using mailed questionnaires from a random sample of Australian private general practice dentists in 2007 (response rate = 77%).
Median responsibility loadings were 1.25 for an initial oral examination and for a 3+-surface amalgam restoration, 1.50 for a simple extraction and for root canal obturation (single canal), and 1.75 for subgingival curettage (per quadrant). Across the five services coefficients from a multivariate logit model showed that ratings of importance of knowledge (0.34), dexterity (0.24), physical effort (0.28) and mental effort (0.48) were associated with responsibility loadings (P < 0.05).
The elicited median responsibility loadings showed agreement with previous estimates indicating convergent validity. Components of responsibility were associated with loadings indicating that components can explain and predict responsibility aspects of dental service provision.
责任比重决定了牙科服务的相对价值单位,将服务转化为一种通用的工作努力尺度。本文的目的是确定一组牙科服务的责任比重,并将责任比重与责任组成部分的重要性评分联系起来。
2007 年,通过邮寄问卷的方式,从澳大利亚私人普通执业牙医的随机样本中收集责任比重和责任组成部分的重要性评分(应答率=77%)。
初始口腔检查和 3+表面银汞合金修复的中位数责任比重为 1.25,简单拔牙和根管充填(单根管)的中位数责任比重为 1.50,龈下刮治(每象限)的中位数责任比重为 1.75。在这五个服务中,多变量逻辑回归模型的系数表明,知识(0.34)、技能(0.24)、体力(0.28)和脑力(0.48)的重要性评分与责任比重相关(P<0.05)。
得出的中位数责任比重与之前的估计值一致,表明具有收敛效度。责任组成部分与比重相关,表明组成部分可以解释和预测牙科服务提供的责任方面。
