Geoff Spurling and colleagues report findings of a systematic review looking at the relationship between exposure to promotional material from pharmaceutical companies and the quality, quantity, and cost of prescribing. They fail to find evidence of improvements in prescribing after exposure, and find some evidence of an association with higher prescribing frequency, higher costs, or lower prescribing quality.
杰弗里·斯珀林(Geoff Spurling)及其同事报告了一项系统评价的研究结果,该评价旨在研究接触制药公司的促销材料与处方的质量、数量和费用之间的关系。他们没有发现接触后处方改进的证据,反而发现了一些与更高的处方频率、更高的成本或更低的处方质量有关的证据。
