Safer Systems, Safer Care: Bringing the Tools and Strategies to Clinical Service Areas Through Applied Patient Safety Programs

AbstractAlong with creating and supporting a trained network of Patient Safety Managers across the U.S. Veterans Health Administration, the National Center for Patient Safety brings an increased, shared awareness of patient safety goals and strategies to disciplines of healthcare, beginning with the biomedical engineers at VHA facilities. This presentation outlines a ‘roadmap’ for the journey to high reliability healthcare and shares the training approach and results to date. This roadmap is modelled after that used at NASA and contains four development phases beginning with an awareness of human limitations and ending with proactive analysis to anticipate causes of safety episodes. The goal of the roadmap is to systematically ensure the care given to patients is done as safely as possible by incorporating best practices from mature industries

Susceptibility to Taura Syndrome Virus of Some Penaeid Shrimp Species Native to the Gulf of Mexico and the Southeastern United States

Experimental studies demonstrated that Penaeus setiferus, but not Penaeus aztecus or Penaeus duorarum, could be killed by Taura syndrome virus (TSV). However, specimens of P. setiferus that survived infection and both P. aztecus and P. duorarum at least 79 days postexposure that did not demonstrate gross signs of infection were shown to harbor virus by bioassay using Penaeus vannamei, a highly susceptible target host. Consequently, all three of those penaeids native to the southeast United States can serve as carriers or reservoir hosts of TSV without necessarily exhibiting disease. Infections in P. setiferus took longer to cause mortality than in P. vannamei and killed a smaller percentage of that host. Also, histological lesions diagnostic of TSV infection were not always evident in sectioned tissue of infected P. setiferus, and they generally were more conspicuous during Days 4–7 postexposure compared with lesions that also occurred at both earlier and later days in tissues of P. vannamei. Infections could be produced by injection, ingestion, and incorporation of the infective material into dietary brine shrimp. There appeared to be a difference in susceptibility to TSV disease by different stocks of P. setiferus, but different experiments produced conflicting evidence regarding a relationship between age and predilection to mortality. Large and small specimens of equal-aged shrimp succumbed similarly to TSV infections for both P. vannamei and P. setiferus. The nonnative species P. chinensis demonstrated a high susceptibility to experimental TSV disease

What Do You Say to Teasers? Parent and Child Evaluations of Responses to Teasing

Teasing is a common and sometimes problematic event in childhood that has received little empirical attention. In the current study, target responses to teasing were manipulated by editing an ignore, empathy-inducing, humorous, or hostile reaction to a child\u27s teasing into a videotaped story. Parents (n = 117) and their children (n = 147) rated these responses and gave information about their own teasing experiences. Parents and children both approved of the nonhostile responses more than the hostile response but disagreed on several of the open-ended items about their experiences with teasing. Response preferences varied by the child\u27s gender and his or her experiences with teasing. Implications for parental advice about teasing are discussed
