Abstract: Objective To explore the working mode in which clinical pharmacists participate in the control of high-risk drugs and promote medication safety.Methods Clinical pharmacists participated in pharmaceutical service to high-risk drugs using the pipeline service system model. The pipe head indicated control measures. The pipe wall indicated not only good cooperation between clinical pharmacists and doctors and nurses while controlling high-risk drugs but also a safe medication channel during interactions with patients. The pipe end indicated that by means of follow-up and assessment of patients using high-risk drugs, clinical pharmacists optimized medications, hence the elastic circular effect with the pipe head at any time. The levels of knowledge of high-risk drugs by nurses were compared by the scores of numerical rating scale.Results After the adoption of the pipeline service model, nurses’levels of knowledge of high-risk drugs were improved( 40.0% to 88.9%).Among the 204 patients prior to the implementation of the pipeline service model, the total number of cases of irrational use of high-risk drugs accounted for 49.5%, compared with 36.1% after the pipeline service model was adopted. The number of proper medications improved.Conclusion Use of the pipeline service system model can help ensure the safety of high-risk drugs.

Key words: pipeline service system model, clinical pharmacists, high-risk drugs
