Assessment of the safety climate in outpatient diagnostic services: Development and psychometric evaluation of a questionnaire.
Article in European radiology, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionSafe practice and safety culture are important issues in outpatient diagnostic imaging services. As questionnaires assessing safety culture through the measurement of safety climate in this setting are not yet available, the present study aimed to develop and validate such an instrument. MATERIALS AND
methodsAfter adaptation of an existing questionnaire and qualitative pretesting, the instrument was tested by collaborators from three outpatient imaging services in Switzerland. Results were first assessed using descriptive statistics. Scores of individual services were compared using a Wilcoxon test assessing differences between rank distributions. The final instrument was tested for validity using inter-rater agreement measures, such as reliability within groups (r
resultsSafety climate scores vary significantly between services. Inter-rater agreement measures show that item aggregation is justified and that the instrument distinguishes various patterns of safety climate. The final instrument proves to be valid, consistent and reliable.
conclusionsThe final instrument presents a valid, consistent and reliable option to measure safety climate in outpatient diagnostic imaging services. Results can be used as a basis for quality improvement. KEY POINTS: • An adapted questionnaire that assesses safety climate in outpatient diagnostic imaging services was developed and tested in Switzerland. • Psychometric evaluation showed the questionnaire to be a valid, consistent and reliable instrument. • Results are of interest for imaging services as well as for stakeholders interested more globally in monitoring and quality improvement.
