The questionnaire consisted of six parts with 44 questions and the full questionnaire can be accessed by contacting the authors. The first four parts were based on a conceptual framework developed by Patel et al [20] to guide systematic planning for community primary care service response to pandemic influenza with modifications to make it more relevant for nurses. We added a fifth part on psychological responses to pandemic influenza and a sixth part on demographics of respondents which were based on two studies previously published (one on general practitioners' response to SARS and one on general public response to swine flu) [21, 22] . In summary, these sections were 1) clinical services change as a response to pandemic influenza; 2) internal environment changes as a response to pandemic influenza e.g. wearing of mask; 3) macro-environmental changes as a response to pandemic influenza e.g. use of guideline etc; 4) professional and public health responsibilities with respect to pandemic influenza; 5) attitude and psychological responses to pandemic influenza; and 6) demographics and year of education of respondents. The willingness to accept influenza A(H1N1) vaccination was asked in the professional and public health responsibility sections and the question "will you receive the new influenza A (H1N1) vaccine when it is available" was asked with a dichotomous "yes" or "no" response. For those who answered no, they were further asked to give their reasons for refusing to receive the vaccine. Only results on willingness of accept influenza A (H1N1) vaccination and information related to the analysis on willingness to accept vaccine are reported in this paper. Other results from this survey will be presented in a separate report.
