However, integrated care programs did not necessarily lead to the changes intended in experiences and outcomes. We attribute this gap between expectations and results, in part, to significant misalignment between the aspiration for unity underpinning conceptual models on the one hand and the multiplicity of practical application of strategies to integrate care on the other. Conclusions Those looking for universal answers to narrow questions about whether integrated care "works" are likely to remain disappointed. Models of integrated care need to be valued for their heuristic rather than predictive powers, and integration understood as emerging from particular as well as common contexts.Objective H1N1/09 was the first pandemic flu ever responded to with mass vaccinations. Public health nurses (PHNs) were pivotal in implementing the H1N1/09 vaccination clinics. With the ongoing threat of pandemic influenza and other viral outbreaks, much can be learned from these PHNs' H1N1/09 experiences. This study's purpose was to explore PHNs' experiences in the H1N1/09 mass vaccination clinics. Design and sample In a qualitative interpretive description, 23 PHNs (16 immunizers, seven supervisors) who worked in a large Canadian municipal public health agency, participated in semistructured interviews. Results Three overarching themes were identified. 'Anticipating an Emergency' discusses participants' experiences learning about the pandemic response and their role preparation. 'Surviving the Chaos' reflects the challenges of the clinics, particularly during the first few hectic weeks of the response. 'Persevering Over Time' encompasses participants' experiences as they became familiar with clinics' operations and their own responsibilities. Conclusions Participants' experiences have implications for future public health pandemic planning and research. Key recommendations include to
