Our aim was to measure the safety climate in our unit, compare it with benchmarking data, and identify potential deficiencies. Design: Prospective longitudinal survey study at two points in time. Setting: Pediatric surgical intensive care unit at a Dutch university hospital. Subjects: All unit personnel. Interventions: To measure the safety climate, the Safety Attitudes Questionnaire was administered to physicians, nurses, nursing assistants, pharmacists, technicians, and ward clerks in both May 2006 and May 2007. This questionnaire assesses caregiver attitudes through use of the six following scales: teamwork climate, job satisfaction, perceptions of management, safety climate, working conditions, and stress recognition. Earlier research showed that the Safety Attitudes Questionnaire has good psychometric properties and produced benchmarking data that can be used to evaluate strengths and weaknesses in a given clinical unit against peers. Measurements and Main Results: The response rates for the Safety Attitudes Questionnaire were 85% (May 2006) and 74% (May 2007). There were mixed findings regarding the difference between physicians and nurses: on three scales (i.e., teamwork climate, safety climate, and stress recognition), physicians scored better than nurses at both points in time. On another two scales (i.e., perceptions of management and working conditions), nurses consistently had higher mean scale scores. Probably due to the small number of physicians, only some of these differences between physicians and nurses reached the level of statistical significance. Compared to benchmarking data, scores on perceptions of management were higher than expected (p < .01), whereas scores on stress recognition were low (p < .001). The scores on the other scales were somewhat above (job satisfaction), close to (teamwork climate, safety climate), or somewhat below (working conditions) what was expected on the basis of benchmarking data, but no persistent significant differences were observed on these scales. Conclusions: Although on most domains the safety culture in our unit was good when compared to benchmark data, there is still room for improvement. This requires us to continue working on interventions intended to improve the safety culture, including crew resource management training, safety briefings, and senior executive walk rounds. More research is needed into the impact of creating a safety culture on patient outcomes. http://repub.eur.nl/res/pub/31725/ 2011-01-01T00:00:00Z Objectives: To evaluate availability and reliability of pediatric drug dosing guidelines in selected formularies for intensive care patients. Most drugs used in the pediatric intensive care unit are prescribed off-label, often on the guidance of limited information from commonly used drug formularies. Design: Availability of dosing information on prescribed drugs in a Dutch intensive care unit from January 1, 2005 to December 31, 2006 was compared among four selected formularies (Micromedex, Lexi-Comp, Drug Formulary for Children, Drug Doses). Reliability of dosing guidelines was assessed by evaluating labeling status and literature data for the three most (midazolam, acetaminophen, and amoxicillin/clavulanic acid) and the three least (bosentan, ketanserin, and iloprost) prescribed drugs. Measurements and Main Results: The selected formularies covered 68% to 86% of all 257 prescribed drugs. Guidelines differ widely on daily doses per kilogram, dose description, dosing regimen, and age ranges. For the three most prescribed and one of the least prescribed drugs (bosentan), dosing guidelines adequately reflected labeling status and existing (but scarce) literature. No dosing guidelines were available for iloprost, and only one dosing guideline was available for ketanserin. Conclusions: This study shows that four commonly used drug formularies give few and widely differing dosing guidelines for drugs prescribed in the intensive care unit. If guidelines exist, they seem to reflect labeling status (if present) and limited literature available. Findings from this study likely reflect the scarcity of drug studies in this population. Physicians should be aware of the limitations of these formularies for daily practice in this group of vulnerable patients.

The incidence of withdrawal or limitation of therapy in this group is unknown. Purpose: To assess mortality and characteristics of children admitted for ≥28 days to our ICU, and to describe the extent to which limitations of care were involved in the terminal phase preceding death. Methods: For the period 2003 to 2005 clinical data were collected retrospectively for children with prolonged stay (defined as ≥28 days) in a medical/surgical PICU of a university children's hospital. Results: In the PICU, 4.4% of the children (116/2,607, equal gender, mean age 29 days) had a prolonged stay. Median (range) stay was 56 (28-546) days. These children accounted for 3% of total admissions and occupied 63% of total admission days. Mortality during admission for this group was five times higher (22%) than the average PICU mortality rate of 4.6%. Withdrawal or limitation of therapy preceded 70% of deaths. Conclusions: Children with prolonged stay in the PICU have a significantly high risk of mortality. Death is typically preceded by limitation of care.
