RESUMO
AIM: To document adherence to influenza, pneumococcal and hepatitis B virus (HBV) vaccination programme in adult type 1 diabetes mellitus (T1DM) patients. MATERIALS AND METHODS: Observational retrospective study using data obtained from computerized clinical records. We contacted all adult T1DM registered in our database from a tertiary diabetes care hospital. Primary efficacy outcome was to describe influenza, pneumococcal and HBV vaccination status. RESULTS: Three hundred patients were analyzed (male 53%). Mean age was 40.0±14.4years and T1DM duration was 19.7±11.8years. Thirty-five percent of the patients had complementary indications for studied vaccines. Adherence to vaccination program for influenza, pneumococcal and HBV was achieved by 55%, 18% and 17% of the patients, respectively. Only 3% of the subjects were vaccinated against the three microorganisms. Predictor of correct vaccination were: age, shorter diabetes duration, insulin pump treatment, better diabetes control and being a health professional. We detected 17 sick leaves, 127 lost working days and 3 hospitalizations due to flue during the follow-up. CONCLUSIONS: The uptake of recommended vaccinations against influenza, pneumococcal and HBV in adult T1DM patients was below desirable levels. A special effort is required to all health professionals to implement immunization among adult people with T1DM. Clinical Trials NCT03478254.
