Most plans were sketchy on systems to maintain non-influenzarelated clinical care, with the exception of some PCT plans, which included activities like triage, extended prescribing, identifying deferrable reasons for presentation, and management of more acute problems to protect hospitals [29, [33] [34] [35] [36] . The main non-influenza clinical area was mental health care, mentioned in six plans from the USA [37] [38] [39] [40] [41] [42] (reflecting a focus in the national plan [43] ) and one Canadian plan [44] . Coverage of the needs of vulnerable populations-the elderly, homeless, prisoners and the psychologically unwell -was most detailed in plans from Canada and England.
