Quantitation of the Global Right Ventricular Function in Children with Normal Heart and Congenital Heart Disease: A Right Ventricular Myocardial Performance Index

Although the assessment of right ventricular (RV) function is important in the clinical management of children with congenital heart disease, available imaging techniques have been limited because of the complex geometry of the right ventricle. A new Doppler index combining systolic and diastolic time intervals (the Tei index) has been reported to be useful for the assessment of global RV function in adults. However, normal values in children, age-related changes, and the clinical utility of the Tei index with regard to congenital heart disease have not been demonstrated. The purpose of this study was to prospectively assess RV function in children with normal heart and congenital heart disease using the Tei index. The subjects included 150 healthy children and 43 patients with congenital heart disease (35 patients with atrial septal defects and 8 patients who had had a Senning operation). The index was defined as the sum of isovolumetric contraction time and isovolumetric relaxation time divided by ejection time and was measured from conventional RV outflow and inflow Doppler velocity profiles. The Tei index was not affected by age in healthy children (0.24 ± 0.04). There was a significant difference in index rating between patients who had had a Senning operation (0.58 ± 0.09) and healthy children (p < 0.01), but there was no significant difference between children with atrial septal defect (0.25 ± 0.13) and healthy children. The Tei index is a feasible approach to use when assessing global RV function in children with congential heart disease.     

A Danish version of the MISSCARE survey: Translation and validation

Background

Measuring missed nursing care in clinical settings may serve as an important indicator for improving patient safety and nursing staff retention. Internationally, several tools exist, with the MISSCARE Survey being the most frequently used and validated; however, no tools are available in the Danish language.

Aim

This study aimed at translating the MISSCARE Survey from US English to Danish and evaluate its psychometric properties.

Methods

The translation followed the recommended method, that is forward-and-backward translation, involving clinical experts and a professional, native English-speaking translator. The final version was approved by the survey's original developer. Face validity was tested among 10 nurses and 1 practical nurse. Nursing staff from 34 selected departments at Aarhus University Hospital's (n = 1241) were invited to participate in a pilot test in November 2020. The survey consisted of a demographic section, a section of ‘nursing elements’ (Part A) and section of ‘reasons’ (Part B). Acceptability was assessed on Part A and B. Reliability was tested by Cronbach's alpha, and psychometric properties were investigated using Confirmatory Factor Analysis (Part B).

Results

The face-validity test resulted in minor contextual changes and the addition of a ‘not applicable’ response option in Part A. The pilot test had a 42.6% response rate (n = 529). Acceptability was good, with 1–10 missing responses per item in Part A and 0–20 missing responses in Part B. The numbers of ‘not applicable’ responses ranged from 0 to 81. The overall Cronbach's alpha was 0.81. Factor-loading ranges were 0.62–0.48 for ‘communication’, 0.79–0.39 for ‘materials and resources’, and 0.50–0.35 for ‘labour’, suggesting an acceptable fit with the theoretical model.

Conclusion

The MISSCARE Survey was successfully translated into Danish. The psychometric properties confirmed the questionnaire as a valid and reliable tool for measuring missed nursing care in Danish hospital settings.
