Impact of physicians' attitude to vaccination on local vaccination coverage for pertussis and measles in Germany.

ABSTRACT

BACKGROUND: Vaccination rates of children in Germany are unsatisfying and regional endemic outbreaks have been reported. Few studies have analysed physicians' attitude towards vaccination. We investigated whether there is an association between physicians' attitude and vaccination coverage on the regional level for Germany. METHODS: In a representative cross-sectional survey, anonymized questionnaires were sent to random samples of all paediatricians (50%) and general practitioners (10%) in private practice in Germany. Attitude towards vaccination was operationalized in three scores. Measles and pertussis vaccination coverage rates were obtained from the 16 Federal States' Health Departments. Geographic methods and linear regression models were used for analysis. RESULTS: A total of 2010 paediatricians (response proportion 64.1%) and 1712 general practitioners (response proportion 39.1%) were included in the analysis. We found an association of physicians' attitude towards vaccination and vaccination coverage rate (P < 0.0001). There is also an important association between vaccination coverage and the geographic location, with lower coverage rates especially in the States of former Western Germany (compared with our reference State Mecklenburg-Western Pomerania; pertussis maximum -5.86% in Bavaria, P < 0.0001; measles maximum -20.20% in Berlin, P = 0.0002). CONCLUSIONS: The regional association between vaccination coverage rates and physicians' attitude towards vaccination seems to be superposed by population-related variables. An increase of vaccination coverage requires better information and training of both, physicians and the general population.
