To determine the relative effects of population size, FP and GP supply, and other specialist supply on chemistry and hematology test volumes (ie, number of tests performed).
Population-level analysis using secondary data from the Calgary Health Zone for 2004 to 2009.
Calgary, Alta.
The relative effects of population size, FP and GP supply, and other specialist supply on laboratory test use.
Population size was the strongest predictor of test volumes in a multivariate analysis. The FP and GP supply was significantly negatively correlated with chemistry test volume (partial r(2) = 0.186, P = .045). There was a trend toward decreasing use of hematology tests with increasing FP and GP supply (partial r(2) = 0.117, P = .119).
The relationship between FP and GP supply and laboratory test use is complex, but increasing numbers of FPs do not necessarily indicate an increase in laboratory test use and might be associated with a decrease in test use when other factors are controlled for.
确定人口规模、家庭医生和普通医生供应以及其他专科医生供应对化学和血液测试量(即进行的测试数量)的相对影响。
利用 2004 年至 2009 年卡尔加里卫生区的二级数据进行人群水平分析。

人口规模、家庭医生和普通医生供应以及其他专科医生供应对实验室检测使用的相对影响。
在多变量分析中,人口规模是测试量的最强预测因素。家庭医生和普通医生的供应与化学测试量呈显著负相关(偏相关系数为 0.186,P=0.045)。随着家庭医生和普通医生供应的增加,血液测试的使用呈下降趋势(偏相关系数为 0.117,P=0.119)。
家庭医生和普通医生供应与实验室检测使用之间的关系很复杂,但增加家庭医生和普通医生的数量并不一定表示实验室检测使用增加,并且当控制其他因素时,这种供应的增加可能与检测使用的减少有关。
