The computer system for billing prescriptions (SIFAR in Spanish) enables indicators to be extracted for the study and follow-up of the use of medicines in the INSALUD primary care areas. Concretely, we studied the indicator referring to pensioners consumption of lipid-lowering drugs (PCLL), not validated, and whose value is expected to drop as quality increases. The objective was to calculate the correlation of the indicator of prescription of lipid-lowering drugs on the SIFAR with the proportion of lipid-lowerers prescribed correctly for pensioners (PCP).
A descriptive study of correlation between two indicators of drug prescription.
Four health districts in Madrid.
The prescriptions of 49 general practitioners, chosen at random on the basis of three strata defined by the value of the indicator, were studied. Each doctor filled out a protocol of data for each pensioner patient to whom he/she prescribed a lipid-lowerer during the study period.
The PCLL and PCP indicators were compared through the correlation of Spearman. 6,779 prescriptions for 1,125 patients were collected from the 49 participating doctors. The mean percentage of lipid-lowerers correctly prescribed was 31.9%, figure that rose to 77.5% when the LDL value was not specified. The correlation between the PCLL and the PCP was near zero.
The PCLL indicator of the SIFAR does not discriminate quality in lipid-lowering drug prescription to people over 64.
处方计费计算机系统(西班牙语为SIFAR)能够提取指标,用于研究和跟踪国家卫生服务局初级保健领域的药物使用情况。具体而言,我们研究了一项针对领取养老金者降脂药物消费情况的指标(PCLL),该指标尚未经过验证,并且预计随着质量的提高其数值会下降。目的是计算SIFAR上降脂药物处方指标与领取养老金者正确开具降脂药物的比例(PCP)之间的相关性。
对两项药物处方指标之间的相关性进行描述性研究。
马德里的四个卫生区。
根据指标值定义的三个层次随机选择49名全科医生的处方进行研究。每位医生为其在研究期间开具降脂药物的每位领取养老金者患者填写一份数据协议。
通过Spearman相关性比较PCLL和PCP指标。从49名参与医生处收集了1125名患者的6779份处方。正确开具降脂药物的平均百分比为31.9%,当未指定低密度脂蛋白值时,这一数字升至77.5%。PCLL与PCP之间的相关性接近零。
SIFAR的PCLL指标无法区分针对64岁以上人群开具降脂药物的质量。
