In China, the adoption of seasonal influenza vaccination among diabetes patients is poor. According to recent research, healthcare workers’ (HCWs’) recommendations are an effective strategy to encourage influenza vaccination. The purpose of this study was to determine the determinants of HCWs’ propensity to offer influenza vaccination to diabetes patients. A self-administered questionnaire on diabetes patients’ perspectives, attitudes, and practices towards influenza vaccination was provided to 1,370 HCWs at 20 hospitals and 20 community health centers in Ningbo between December 2016 and January 2017. Logistic regressions were used to examine the predictors of HCWs’ propensity to promote influenza vaccination. 

Of the 1,340 HCWs that responded to the poll, 58.13% (779/1340) said they would suggest influenza vaccination to diabetes patients. Awareness of the national influenza vaccination guideline (OR: 6.33; 95%CI: 4.66–8.60) and regional reimbursement policy (OR: 1.62; 95%CI: 1.19–2.20), training on influenza and diabetes (OR: 1.65; 95%CI: 1.21–2.23), influenza vaccination history (OR: 1.35; 95%CI: 1.01–1.79), beliefs in vaccine effects on reducing serious consequences (OR: 1.38; 95%CI: 1.01–1.91), reduction in hospitalization costs (OR: 1.43; 95%CI: 1.05–1.94) caused by influenza, and more than 10 years of practitioner experience (OR: 1.60; 95%CI: 1.04–2.46) were all positively associated with recommendation willingness. Concerns regarding the adverse effects of the influenza vaccination were recognized as a barrier to the recommendation.
