The framework identifies four domains of practice: clinical services, public health responsibilities of general practice, internal (physical and organisational) environment of the general practice unit, and the macro-environment of general practice. In each domain, we list the key challenges to be anticipated by general practice during an influenza pandemic, and the type of responses that need to be addressed in the plan. Table 2 summarises the organisational levels in the five countries, the proportion of jurisdictions with accessible pandemic plans, and coverage of general practice in these plans. While almost all plans from US jurisdictions were accessible, three quarters of Australian states/territories and one third of New Zealand's District Health Boards had accessible plans. Only 13% (20/152) of England's PCTs had pandemic plans available in the public domain. Figure S1 shows the jurisdictions and health management systems whose plans were included in this study; they comprise 49 jurisdictions from the USA, 20 from England, 8 from Canada, and 6 each from Australia and New Zealand. Table 3 shows the number and rates of coverage of each of the four domains of the general practice response in jurisdictional plans of the five countries. The domain covered most frequently was influenza-related clinical care (in all plans from England and Canada). Overall less than half the plans mentioned non-influenza clinical care, with the exception being England, where 90% of PCT plans mentioned non-influenza clinical care. Public health surveillance was addressed in all plans from Canada and New Zealand and infection control in general practice in almost all plans from England and Canada. Functional linkages of general practice with other parts of the health system were addressed in almost all the English plans, but a smaller proportion of other plans. Clinical care
