OBJECTIVE To compare expert-generated textual summaries of physiological data with trend graphs, in terms of their ability to support neonatal Intensive Care Unit (ICU) staff in making decisions when presented with medical scenarios. METHODS Forty neonatal ICU staff were recruited for the experiment, eight from each of five groups--junior, intermediate(More)
OBJECTIVES To review the literature to determine the most effective methods for preventing postpartum hemorrhage (PPH), the single most important cause of maternal death worldwide. METHODS Systematic review of published randomized controlled trials and relevant reviews. RESULTS Review of the literature confirms that active management of the third stage(More)
OBJECTIVES We aimed to: (1) assess the association of average, low, high and variable mean blood pressure (mbp) on death and the common morbidities of very low birthweight infants, and in doing so, (2) to derive representative reference ranges for mbp in very low birthweight infants. STUDY DESIGN This five year retrospective study assessed 1 min computer(More)
Despite the clinical and medicolegal significance attached to perinatal asphyxia, the neuropathological basis of this condition remains obscure. There are very few studies in the literature which correlate the pathological findings in neonatal brains with detailed epidemiological data, and none which are population based. In a Scotland-wide study of(More)
The aim of this paper is to describe a novel approach to the analysis of data obtained from card-sorting experiments. These experiments were performed as a part of the initial phase of a project, called NEONATE. One of the aims of the project is to develop decision support tools for the neonatal intensive care environment. Physical card-sorts were performed(More)
This paper presents outcomes from a cognitive engineering project addressing the design problems of computerised monitoring in neonatal intensive care. Cognitive engineering is viewed, in this project, as a symbiosis between cognitive science and design practice. A range of methodologies has been used: interviews with neonatal staff, ward observations, and(More)
The observed physiological dynamics of an infant receiving intensive care are affected by many possible factors, including interventions to the baby, the operation of the monitoring equipment and the state of health. The Factorial Switching Kalman Filter can be used to infer the presence of such factors from a sequence of observations, and to estimate the(More)
The aim of the NEONATE project is to investigate decision support in the neonatal intensive care unit. This paper describes the considerable amount of observational and physiological data which was acquired and as well as the tools which have been developed to analyse them. Both the data and the tools are in the public domain. We believe that our database(More)
BACKGROUND Artifacts in clinical intensive care monitoring lead to false alarms and complicate later data analysis. Artifacts must be identified and processed to obtain clear information. In this paper, we present a method for detecting artifacts in PCO2 and PO2 physiological monitoring data from preterm infants. PATIENTS AND DATA: Monitored PO2 and PCO2(More)
