Determinants associated with doctors' prescribing behaviors in public hospitals in China.
Doctors' prescribing behaviors impact both medical expenses and health resources. This study aims to identify the significant determinants of prescribing behaviors of doctors, which could potentially provide theoretical evidence on how to improve prescribing decisions. A multistage, stratified, cluster, random sampling method was employed in this survey. Data were collected from Jiangsu and Shanxi provinces in China in 2018. A total of 444 doctors in public hospitals completed the self-administered questionnaires. A structural equation model based on the theory of planned behavior (TPB) was adopted for analysis. On the basis of the TPB, we constructed a model of doctors' prescribing behaviors, which explained the subjective and objective reasons for irrational prescribing behavior. Behavioral attitude, subjective norms, and perceived behavioral control could positively influence the actual behaviors, of which subjective norms impact prescribing behaviors the most. Employing the TPB helped in identifying determinants of prescribing behaviors from a new perspective. More significant policy changes and government support are required to help improve appropriate prescribing behaviors and ultimately make better prescribing decisions. This study provided a deeper understanding of this complex issue and will inform the development of a theory and evidence-based intervention for future research.
