Clinical course of ICU patients with severe pandemic 2009 influenza A (H1N1) pneumonia: single center experience with proning and pressure release ventilation.
A number of different modalities have been employed in addition to conventional ventilation to improve oxygenation in patients with severe 2009 pandemic influenza A (H1N1) pneumonia. Outcomes with ventilatory and rescue therapies for H1N1 influenza-related acute respiratory distress syndrome (ARDS) have been varied. A single intensive care unit (ICU) experience with management of laboratory-confirmed 2009 pandemic influenza A (H1N1) ARDS with a combination of proning and airway pressure release ventilation (APRV) is described. ⋯ Proning in combination with APRV provides improvement of hypoxemia with limitation of end-organ dysfunction and thereby facilitates recovery from severe 2009 pandemic influenza A (H1N1).

Public health emergencies have the potential to disproportionately impact disadvantaged populations due to pre-established social and economic inequalities. Internationally, prior to the 2009 H1N1 influenza pandemic, existing pandemic plans were created with limited public consultation; therefore, the unique needs and characteristics of some First Nations communities may not be ethically and adequately addressed. Engaging the public in pandemic planning can provide vital information regarding local values and beliefs that may ultimately lead to increased acceptability, feasibility, and implementation of pandemic plans. Thus, the objective of the present study was to elicit and address First Nations community members' suggested modifications to their community-level pandemic plans after the 2009 H1N1 influenza pandemic. ⋯ Our results illustrate the importance of engaging the public, especially First Nations, in pandemic planning to address local perspectives. The community engagement process used was successful in incorporating community-based input to create up-to-date and culturally-appropriate community-level pandemic plans. Since these pandemic plans are dynamic in nature, we recommend that the plans are continuously updated to address the communities' evolving needs. It is hoped that these modified plans will lead to an improved pandemic response capacity and health outcomes, during the next public health emergency, for these remote and isolated First Nations communities. Furthermore, the suggested modifications presented in this paper may help inform updates to the community-level pandemic plans of other similar communities.

Oseltamivir overuse at a Chicago hospital during the 2009 influenza pandemic and the poor predictive value of influenza-like illness criteria.
We report on the overuse of oseltamivir at Rush University Medical Center, Chicago during the 2009 H1N1 influenza pandemic. Of 210 patients with suspected influenza who underwent respiratory virus reverse transcription polymerase chain reaction (RT-PCR) testing, 113 (54%) received empiric oseltamivir therapy. However, only 50 treated patients (44%) had laboratory confirmed 2009 H1N1. ⋯ However, on multivariate analysis, only subjective fever (p = 0.006, odds ratio (OR) 3.1, 95% confidence interval (CI) 1.4-6.7) and fulfilment of CDC ILI criteria (p = 0.001, OR 3.6, 95% CI 1.7-7.5) were significantly associated with the receipt of oseltamivir. The CDC ILI criteria had a poor positive predictive value of 43% (95% CI 33.3-53.3) for 2009 H1N1. While the ILI criteria are a useful epidemiologic tool, it is too imprecise for direct patient care.

In the spring of 2009, New York City (NYC) experienced the emergence and rapid spread of pandemic influenza A H1N1 virus (pH1N1), which had a high attack rate in children and caused many school closures. During the 2009 fall wave of pH1N1, a school-located vaccination campaign for elementary schoolchildren was conducted in order to reduce infection and transmission in the school setting, thereby reducing the impact of pH1N1 that was observed earlier in the year. In this paper, we describe the planning and outcomes of the NYC school-located vaccination campaign. ⋯ The team model achieved vaccination of more children per day and required fewer vaccination days per school. NYC's campaign is the largest described school-located influenza vaccination campaign to date. Despite substantial challenges, school-located vaccination is feasible in large, urban settings, and during a public health emergency.
