Many countries were not prepared for a pandemic on June 11, 2009, when the World Health Organization (WHO) declared an Influenza Pandemic. Although Pandemic Influenza Preparedness Planning activity for 2011 has declined compared to 2009, we cannot take preparedness planning off the radar due to future potential pandemics. Unless countries develop model Pandemic Influenza Preparedness Plans, the consequences of being unprepared could be devastating to all of humankind. This study identified Critical Success Factors (CSFs) necessary at all levels (local, state, and national) to achieve model Pandemic Influenza Preparedness Planning. Pandemic Influenza Preparedness Planning involves developing a plan in the event of the emergence of an influenza virus that causes serious illness and is spread easily and is sustainable among humans. Once the WHO issues a pandemic influenza alert, all countries should be prepared. Data was collected through surveys, interviews, and benchmarking methods. The goal of identifying CSFs is to provide those factors to countries as well as authorities on a local, state, and national level in order to develop model Pandemic Influenza Preparedness Plans. Several CSFs were identified, they included the following: strong leadership support, plan development, having logical response plans, exercising plans, clear operations and implementation policies, adequate budget/resources, effective public communications and outreach, and staff training. Clearly, there are benefits to providing CSFs for Pandemic Influenza Preparedness Planning. Being prepared can save the lives of millions around the world and as well as reduce economic and social impact. Pandemic Influenza Preparedness Planning should remain a high priority.
