For patients with diabetes, annual seasonal influenza immunisation (SIV) is advised, but vaccine coverage remains low. The study evaluated the likelihood of SIV detention or commencement, its correlations, and the anticipated vaccination time for the different patient profiles across 10 seasons. In 2006, they conducted a retrospective cohort analysis of diabetic patients found in a representative sample of French National Health Insurance Fund beneficiaries. To estimate transition probabilities, they employed a Markov model, and to investigate variables, they utilised a proportional hazards model. The chance of starting or discontinuing sIV was lower than the risk of remaining vaccinated or unvaccinated for the two subsequent seasons. Men, older people, diabetes, diabetes or more, contacts with doctors and any hospitalisation for diabetes or flu have been less likely to begin and/or quit SIV in the past year. In women aged <65 years with untreated diabetes, the mean predicted number of seasons of SIV uptake across 10 seasons was lowest and in males aged 65 years with type 1 diabetes the most.

Doctor contacts and certain clinical circumstances may play a significant impact in SIV adoption. Health workers play a key role in decreasing missed SIV opportunities. Empirical profiles of patients with distinct SIV patterns should inspire them to employ individualised education methods to overcome the hesitation of patients.
