Business continuity was a focus of the English plans, which frequently referenced resources available on the UK Resilience website [56] . This aspect of preparedness was enhanced after the Exercise Winter Willow simulation in February 2007, and new PCT guidelines addressing workforce planning [52] . Some PCT plans addressed the need for general practice resilience in the face of workforce sicknesses [33] , increased aggression from patients, and threatened loss of capacity in single doctor practices [57] . Few plans from other countries discussed business continuity for primary care in such detail. This may be because such issues are felt to be outside the normal purview of state or provinces, and to be the responsibilities of the businesses themselves or corporate interests.
