Poor drug history documentation in admission medical notes: clerking prompts and junior doctor education alone do not significantly reduce errors.

Introduction: Poor drug history documentation on admission may lead to medication errors; a leading cause of avoidable harm.

Aims: To assess the quality of drug histories in the notes of patients admitted to an emergency assessment unit and impact of interventions to improve documentation.

Methods: Data were collected on the accuracy of documentation in 281 drug histories including errors of omission, frequency and dose.

Phylogeny of the Neotropical killifish family Rivulidae (Cyprinodontiformes, Aplocheiloidei) inferred from mitochondrial DNA sequences.

Phylogenetic relationships of 70 taxa representing 68 species of the Neotropical killifish family Rivulidae were derived from analysis of 1516 nucleotides sampled from four different segments of the mitochondrial genome: 12S rRNA, 16S rRNA, cytochrome oxidase I, and cytochrome b. The basal bifurcation of Cynolebiatinae and Rivulinae (Costa, 1990a,b) is supported; however, Terranatos, Maratecoara, and Plesiolebias are rivulins, not cynolebiatins. These three genera, along with the other recognized annual rivulin genera, form a monophyletic clade.
