Healthcare-associated infection reporting validation is essential because this information is increasingly used in public healthcare quality assurances and care reimbursement. Washington State’s validation of central line-associated bloodstream infection reporting applies credible quality sciences methods to ensure that hospital reporting accuracy is maintained. This paper details findings and costs from our experience.

The government publishes 3 different public report surgical site infection (SSI) metrics, all called standardized infection ratios (SIRs), that impact perceived hospital quality. We conducted a non-random cross-sectional observational pilot study of 20 California hospitals that voluntarily submitted colon surgery and SSI data. Discordant SIR values, leading to contradictory conclusions, occurred in 35% of these hospitals.

Little is known about postdischarge surveillance practices currently in place among American hospitals. This survey describes practices used by acute care hospitals covered by Washington State's legislated mandate for public reporting of surgical site infections. While the vast majority of facilities use multiple techniques, wide variation in practices was discovered.

L’arbre. Les arbres du genre Carapa (Meliaceae) sont présents dans toutes les forêts d’Afrique tropicale au niveau de l’équateur, du rift d’Albertine jusqu’au Sénégal et au Mali pour sa distribution la plus septentrionale. En Afrique comme en Amérique tropicale, le carapa est une source importante de Produits Forestiers ligneux (bois) et Non-Ligneux (PFNL). Le fruit et les graines. Le fruit typique de carapa est une capsule à quatre ou cinq valves qui renferment chacune deux à cinq graines, soit un total de huit à vingt graines par fruit. L’extraction de l’huile. Les villageois ramassent les graines tombées au sol avant qu’elles ne soient parasitées ou germées, ce qui est défavorable à la production d’une huile de qualité. L’extraction de l’huile se fait par ébouillantage des graines. L’huile extraite, polyvalente, est la substance issue de la plante qui est la plus utilisée devant les extraits de feuilles, d’écorce et de racines. Le marché. En Afrique, le commerce de l’huile de carapa est essentiellement local et reste une activité très marginale. Une demande accrue émane toutefois de l’utilisation de cette huile comme insecticide naturel dans la culture du coton biologique. Discussion. Compte tenu du potentiel économique de l’huile de carapa, sa commercialisation devrait respecter une rétribution équitable des paysannes afin de mieux rentabiliser la production. Des mesures de protection des arbres de carapa et de leur habitat doivent également être prises pour permettre une gestion de la production d’huile à long terme. La plantation semble être une option durable en vue de la conservation des peuplements naturels de carapa.

Analysis of variance (ANOVA) is used to prevent inflated type I error when hypothesis testing involves comparing more than two groups. If an ANOVA result indicates a statistically significant difference exists somewhere within, the next task is to discover exactly which combination or combinations of those groups account for the significant difference. Among many methods available for that exploration, orthogonal contrasts and relatively simple graphs are noteworthy (Infect Control Hosp Epidemiol 2003;24:544-547).

The Canadian Institute for Health Information (CIHI) maintains databases to report independently on the health of Canadians and the performance of their healthcare system. CIHI recently received funding to improve indicator development for tracking quality, because in Canada we really have very few data that allow us to make comparable observations down to a regional or institution-specific interest level. We have a long way to go, and we recognize that collaboration and partnership is the only way that this development will move ahead.

SHEA and the American Society for Quality's Health Care Division have been collaborating in areas of common concern to improve healthcare quality. We each possess a heritage of different but complementary approaches and stand a better chance of success together than apart. This presentation describes rapid growth of our interdisciplinary, international, special interest group and progress made thus far, as well as challenges facing hospital epidemiologists and quality improvement professionals.

This article focuses on the selection and interpretation of diagnostic tests, emphasizing the importance of understanding how their mathematical parameters affect the information they provide in various settings. The utility and limitations of sensitivity, specificity, predictive value, and receiver operating characteristic (ROC) curves are discussed using catheter-related bloodstream infections as an example. ROC curves have been used for selecting optimal cutoff values for a positive result and for selecting among several alternative diagnostic tests. For example, 16 different tests have been proposed for diagnosis of catheter-related bloodstream infection; ROC analysis provides an effective way to determine which test offers the best overall performance.
