Factors Associated with Influenza Vaccination Information - a Cross-sectional Study in Elderly Primary Care Patients

General practitioners (GPs) play an important role in influenza vaccination. However, reliable data on the influenza immunisation coverage rate in primary care patients are quite rare. Due to a lack of personal and time resources general practitioners cannot afford to collect such data by themselves. Hence fifth-year students have been involved in the scientific data collection during their practical placement in 118 GP practices. Using logistic regression analysis of a representative sample (n=541) plausible factors associated with the influenza immunisation coverage rate have been identified. These factors were found to be both patient- and practice-specific. This practice-oriented study was conducted to improve the available data base on the influenza immunisation coverage rate among elderly patients in primary care settings.
