Improvements in pandemic preparedness in 8 Central American countries, 2008-2012.

BACKGROUND: In view of ongoing pandemic threats such as the recent human cases of novel avian influenza A(H7N9) in China, it is important that all countries continue their preparedness efforts. Since 2006, Central American countries have received donor funding and technical assistance from the U.S. Centers for Disease Control and Prevention (CDC) to build and improve their capacity for influenza surveillance and pandemic preparedness. Our objective was to measure changes in pandemic preparedness in this region, and explore factors associated with these changes, using evaluations conducted between 2008 and 2012. METHODS: Eight Central American countries scored their pandemic preparedness across 12 capabilities in 2008, 2010 and 2012, using a standardized tool developed by CDC. Scores were calculated by country and capability and compared between evaluation years using the Student's t-test and Wilcoxon Rank Sum test, respectively. Virological data reported to WHO were used to assess changes in testing capacity between evaluation years. Linear regression was used to examine associations between scores, donor funding, technical assistance and WHO reporting. RESULTS: All countries improved their pandemic preparedness between 2008 and 2012 and seven made statistically significant gains (p < 0.05). Increases in median scores were observed for all 12 capabilities over the same period and were statistically significant for eight of these (p < 0.05): country planning, communications, routine influenza surveillance, national respiratory disease surveillance, outbreak response, resources for containment, community interventions and health sector response. We found a positive association between preparedness scores and cumulative funding between 2006 and 2011 (R2 = 0.5, p < 0.01). The number of specimens reported to WHO from participating countries increased significantly from 5,551 (2008) to 18,172 (2012) (p < 0.01). CONCLUSIONS: Central America has made significant improvements in influenza pandemic preparedness between 2008 and 2012. U.S. donor funding and technical assistance provided to the region is likely to have contributed to the improvements we observed, although information on other sources of funding and support was unavailable to study. Gains are also likely the result of countries' response to the 2009 influenza pandemic. Further research is required to determine the degree to which pandemic improvements are sustainable.

Hospitalization costs due to severe acute respiratory infection (SARI) in three Central American countries / Costos de hospitalización de infección respiratoria aguda grave (IRAG) en tres países de América Central

Objective: To estimate the direct medical costs of severe acute respiratory infection (SARI) in children and adults from three Central American countries with a bottom-up costing approach. Methods: The costs of inpatients treatment were estimated through the retrospective bottom-up costing in a randomized sample of clinical records from SARI patients treated in teaching tertiary hospitals during 2009 - 2011 period. Activities incurred per patient were registered and a setting-specific cost per activity was acquired. Average cost per patient in the group of children and elderly adults was estimated for each country. In Nicaragua, only the pediatric population was included. Costs were expressed in local currency (2011), American dollars, and international dollars (2005) for country comparison. Results: The care cost per case in children in Guatemala was the cheaper (I$971.95) compared to Nicaragua (I$1,431.96) and Honduras (I$1,761.29). In adults, the treatment cost for Guatemala was the more expensive: I$4,065.00 vs. I$2,707.91 in Honduras. Conclusion: Bottom-up costing of SARI cases allowed the mean estimates per treated case that could have external validity for the target population diagnosed in hospitals with similar epidemiological profiles and level of complexity for the study countries. This information is very relevant for the decision-making.

Objetivo: Estimar los costos directos de la atención de infección respiratoria aguda (IRAG) en niños y adultos en tres países de América Central. Métodos: Los costos de pacientes hospitalizados fueron estimados a través de análisis retrospectivo en una muestra aleatoria de registros de historias clínicas de casos de IRAG tratado en hospitales universitarios durante el periodo 2009-2011. Las actividades incurridas por paciente fueron registradas y un costo especifico para cada sitio fue estimado. El costo por cada niño y adulto mayor fue estimado para cada país. En Nicaragua sólo se incluyó población pediátrica. Los costos fueron expresados en moneda local (2011), dolar americano y dolar internacional (2005). Resultados: El costo por caso en niños en Guatemala fue el más barato (I$971.95) comparado al de Nicaragua (I$1,431.96) y Honduras (I$1,761.29). En adultos, el costo de tratamiento para Guatemala fue el más costoso: I$4,065.00 vs. I$2,707.91 en Honduras. Conclusión: Los costos de tratar casos IRAG estimados a partir de costos promedios pro caso pueden tener validez externa para hospitales con perfiles epidemiologicos similares y nivel de complejidad de atención para los países del estudio. Esta información es muy relevante para la toma de decisiones.

Costos de tratamiento hospitalario de la infección respiratoria aguda grave en niños de Nicaragua / Cost of treatment for severe acute respiratory infection in Nicaraguan children

Objetivo: Estimar los costos de tratamiento hospitalario de la infección respiratoria aguda grave (IRAG) en niños en Nicaragua. Métodos: Se estimaron costos de tratamiento de pacientes hospitalizados a partir del microcosteo retrospectivo de una muestra aleatoria de casos ocurridos durante el periodo 2009-2011 en Nicaragua y atendidos en un hospital pediátrico universitario de alta complejidad. Se calculó una muestra aleatoria de pacientes con diagnósticos de IRAG (CIE-10), según parámetros extraídos de la literatura. En esta, se estimó el costo promedio por paciente. Los costos fueron expresados en moneda local de 2011 y dólares americanos. Resultados: El costo promedio total de atención de caso en niños fue de 314,9 US$ (intervalo de confianza [IC] 95%: 280,1-349,7 US$) y de 971,6 (655,5-1.287,8 US$) para los que requirieron UCI. El 41% de los costos en los que solo requieren hospitalización general se explican por gastos de hotelería, mientras que en los que requieren UCI el 52% es por medicamentos. Conclusión: El microcosteo de los casos incluidos de IRAG permitió estimar un valor medio por caso tratado, con sus respectivos IC y estos podrían tener validez para el total de la población atendida por estos diagnósticos en hospitales con similar perfil epidemiológico y similar nivel de complejidad en Nicaragua.

Objective: To estimate the costs of treatment for severe acute respiratory infection (SARI) in children in Nicaragua. Methods: A cost assessment was carried out on a random sample of inpatients during 2009-2011 who were treated in one pediatric universitary hospital in Nicaragua. A random sample of patients diagnosed with SARI (ICD-10) was calculated based on parameters from the literature. The average cost per patient was estimated. Costs were expressed in local currency and US dollar values in 2011. Results: The total average cost of healthcare per case was US$314.9 (confidence interval [CI]95%: 280.10-US$349.70) and US$971.60 (655.50-US$1287.80) for those requiring intensive care unit (ICU). Around 41% of the general hospitalization costs are due to the cost of the hospitalization while for those costs involving ICU care, 52% are due to drugs costs. Conclusion: We estimated an average cost per case expressed with their respective CI by microcosts analysis for SARI health care in Nicaraguan children. These costs may be representative of the population with this diagnosis in Nicaraguan hospitals with similar epidemiological profile.
