Cumplimiento de los protocolos de prevención de la legionelosis en edificios públicos / Legionnaires' disease prevention protocol performance in public buildings

Objetivo Investigar la relación entre el cumplimiento del Real Decreto 865/2003 y el Decreto 287/2002, por los que se establecen los criterios higiénico-sanitarios para la prevención y control de la legionelosis, y el riesgo debido a un deficiente mantenimiento higiénico- preventivo de las instalaciones de agua. Métodos Estudio descriptivo realizado en la provincia de Málaga (España) sobre una muestra correspondiente a 214 edificios públicos, 83 variables e interpretación sobre el porcentaje de cumplimiento de la normativa. Medida del riesgo, definición de clusters (tipificación del riesgo), estimadores clásicos y robustos, estimación jackknife e intervalos de confianza bootstrap . Resultados Riesgo por incumplimiento parcial entre el 11,1 (riego, Centros Privados de ESO) y 85,7 por ciento (AFS, Institutos de Educación Secundaria). La normativa se cumple en 82 edificios, 130 la incumplen y 2 no presentan instalaciones de riesgo. Cumplimiento total 38 por ciento. Estimación para el cumplimiento parámetros de localización 0,33-0,36 (33-36 por ciento) y de escala 0,11-0,16. Estimador jackknife del sesgo reducido 0,35071 (estimación media). Intervalos de confianza bootstrap con extremos [0.26, 0.47]. Conclusión El menor riesgo por incumplimiento parcial corresponde a Institutos de Educación Secundaria y el mayor por distribución a los hoteles de cuatro y tres estrellas. Selección del parámetro de localización estimador de Huber y de escala NMAD . Atendiendo al parámetro "razón poblacional" y estimador "razón muestral", el estimador jackknife del sesgo reducido es insesgado. Intervalos de confianza basados en las técnicas bootstrap , partiendo de la media 0,2- recortada muestral y coeficiente de confianza 0,95, muy aproximados.

Objective Studying the relationship between fulfilment of royal decree 865/2003 and decree 287/2002 (establishing hygienic-sanitary criteria for preventing and controlling Legionnaires' disease) and risk arising from deficient preventative-hygienic water facility maintenance. Methods This was a descriptive study carried out in the province of Málaga (Spain) on a sample of 214 public buildings using 83 variables and interpreting legislation fulfilment percentages. Risks were measured, clusters defined (related to risk typification) and classic and robust estimators, jack-knife estimation and bootstrap confidence intervals were calculated. Results 11.1 percent (irrigation, ESO private centres) and 85.7 percent (AFS, secondary education institutions) partial non-fulfilment/breach risks were found. Eighty-two buildings complied with current standards, 130 failed to fulfil them and 2 did not display risk facilities. There was 38 percent overall compliance with established norms. Location parameter fulfilment was estimated as being 0.33-0.36 (3336 percent) and scale as 0.110.16. Reduced bias jack-knife estimator was 0.35071 (average estimation). Bootstrap confidence interval extremes were 0.26 and 0.47. Conclusion Secondary education institutions represented the least risk due to partial noncompliance and four- and three-star hotels the greatest. Huber estimator was selected as location parameter and NMAD as scale parameter. Regarding the population ratio parameter and sample ratio estimator, it was considered that the jack-knife estimator of reduced bias was unbiased. Confidence intervals based on bootstrap techniques (starting from 0.2trimmed mean sample and a 0.95 confidence coefficient) were very approximate.

Investigation on the Hygienic State of 736 Hotels with the Hygienic Quantified and Classified Method in Haidian District, Beijing / 环境与健康杂志

Objective To explore the basic health state of the hotels in Haidian District. Methods 736 hotels were chosen to investigate on the hygiene state, in Haidian District, Beijing, during Feb.-Jul., 2006, based on the tables for the hygienic quantified and classified management of hotel health supervision. Results The hygienic quantified and classified standard score of 736 hotels was 53.7?22.6, and the standard score of the common hotels, one or two stars hotels and three or more stars hotel were 50.9?21.5, 58.9?24.7, 76.4?17.1. 50 households (6.8%) within them were A degree, 144 households (19.6%) were B degreee, 121 households(16.4%) were C degree and 421 households(57.2%) were D degree. Conclusion The general hygienic state of the hotels should be paid more attention to. The hygienic state changes with the level of the hotels.

The Exploration for Inspector Effect on the Hygienic Quantified and Classified Score of the Hostels / 环境与健康杂志

Objective To explore the health inspector effect on the score of hygienic degree of hostels. Methods Using the scale for hygienic degree of hostels, 38 health inspectors from 9 sections in the Bureau for Health Inspection and Supervision of Haidian District in Beijing, scored 621 hostels in the district. The multilevel statistics model has been used to analyze the health inspector effect, of which the index is intra-class correlation (ICC), in the double level model structured by hostels as the level 1 unit and inspectors as the level 2 unit, and in the triple level model structured by hostels as the level 1 unit, inspectors as the level 2 unit and the sections as the level 3 unit. Results In the double level model, ICC of the level 2 unit is 0.142 8. In the triple level model, ICC of the level 2 unit is 0.0000 and ICC of the level 3 unit is 0.154 1. Conclusion There is inspector effect influencing the score of hygienic degree. And the effect seems to be more similar in one section comparing with the other ones.
