Data on comorbidities including infections, treatment, vaccination status, screening for latent tuberculosis infection (LTBI) and hepatitis B (HepB) were collected. Antibodies against measles and HepB were measured by ELISA. The vaccination status was assessed by a predefined vaccination score (0–26) categorising patients into four immunisation states: low (0–6), moderate (7–13), good (14–20), high (21–26).Results All patients on bDMARDs (n=499) were screened for LTBI, and 469 for HepB (94%). All LTBI patients (n=16) received isoniazid (3.2%) and 16 chronic HepB patients received lamivudine (3.4%). Protective measles specific IgG-antibodies were found in 901 patients (92.4%). Although 629 patients were educated about vaccination strategies (64.5%), only 540 showed a vaccination card (55.4%). Only 49% of patients had undergone pneumococcal vaccination and less than 30% were protected against HepB and influenza, while 7.6% have not protective antibody titres against measles. No patient met the German national vaccination recommendations requiring a complete documentation of vaccines. The mean vaccination score was 13.3±4.2 with 5.7% of patients having a low, 43.9% a moderate, 47.0% a good and 3.3% a high score.Conclusions The majority of CIRD patients are n0t sufficiently vaccinated against pneumococci, HepB, influenza and measles. Although CIRD patients and general practitioners regularly receive professional information about the need of vaccination, vaccination rates were low to moderate. Interdisciplinary quality projects should be planned to change that inacceptable result.Data are available upon reasonable request.
