Cross-Sectional Study on Attitudes among General Practitioners towards Pneumococcal Vaccination for Middle-Aged and Elderly Population in Hong Kong

OBJECTIVE To study the attitudes among general practitioners towards pneumococcal vaccination for middle-aged (50-64) and elderly population (over 65) in Hong Kong and the factors affecting their decision to advise pneumococcal vaccination for those age groups. DESIGN Cross-sectional study of general practitioners in private practice in Hong Kong. PARTICIPANTS Members of Hong Kong Medical Association delivering general practice services in private sector. MEASURING TOOL Self-administered questionnaire. MAIN OUTCOME MEASURES Intention to recommend pneumococcal vaccination, barriers against pneumococcal vaccination. RESULTS 53.4% of the respondents would actively recommend pneumococcal vaccination to elderly patients but only 18.8% would recommend for middle-aged patients. Consultation not related to pneumococcal vaccine was the main reason for not recommending pneumococcal vaccine (43.6%). Rarity of pneumonia in their daily practice was another reason with 68.4% of respondents attending five or less patients with pneumonia each year. In multivariate analysis, factors such as respondents would get vaccination when reaching age 50 (ORm 10.1), and attending 6 pneumonia cases or more per year (ORm 2.28) were found to be associated with increasing likelihood for recommending vaccination to the middle-aged. While concerns of marketing a product (ORm 0.41), consultation not related to vaccination (ORm 0.45) and limited time (ORm 0.38) were factors that reduced the likelihood. CONCLUSION Public policy is needed to increase the awareness of impact of pneumococcal pneumonia and the availability of preventive measures.
