Building a novel self-iterative clinical pharmacist intervention model in psychiatric hospital: Application and...

Clinical pharmacist intervention (CPI) in psychiatric hospital has not been widely developed in China. This study aimed to establish a real-time dynamic self-iterative CPI model in The Affiliated Mental Health Center of Jiangnan University and evaluated its effect. We focused on the running data in 2021 and 2022. The number of interventions, intervention types and intervention strategies were evaluated. In 2021 and 2022, a total of 443 interventions were reported. Among them, 271 (61.17 %) were identified during ward rounds by physicians, pharmacists and nurses. The proportion of CPI through ward rounds and information system gradually decreased while intervention through other ways increased. Meanwhile, there are various of CPI types including adverse drug reactions (26.86 %), therapeutic drug monitoring recommendations (13.32 %), drug usage and dose adjustment (10.61 %) and among them, adverse reactions are the focus of pharmacists' attention. Besides, the intervention strategies of pharmacists mainly concentrated in medication change (18.74 %), medication discontinuation (15.58 %) and dose reduction (12.19 %). In addition, the self-iterative function can continuously optimize the intervention level of clinical pharmacists. Overall, the CPI model established in this study effectively promote pharmacist intervention and accelerate pharmaceutical transformation.
