[Clinical indicators of "ineffective breathing pattern" in children with congenital heart disease].

UNLABELLED

Clinical indicators of ineffective breathing pattern in children with congenital heart disease.

OBJECTIVES

To analyze the accuracy of clinical predictors of nursing diagnosis "Ineffective breathing pattern in children with congenital heart disease".

METHOD

1:1 case-control study with 30 children with congenital heart disease. Fifteen children with the nursing diagnosis "Ineffective breathing pattern" (cases) were compared with other 15 without this diagnosis (controls). A total of 15 clinical indicators were analyzed for their sensibility, specificity, predictive values, likelihood ratios and area under the ROC curve.

RESULTS

Four indicators showed an area under the ROC curve > 70%: chest x-ray findings (0.750), adventitious breath sounds (0.737), coughing (0.710) and asymmetric chest expansion (0.702). The indicators of the chest x-ray findings and adventitious breath sounds had a better overall performance for the identification of ineffective breathing pattern.

DISCUSSION

These findings suggest that both indicators can be useful for inference of ineffective breathing pattern. Moreover, the presence of the diagnosis was associated with a greater likelihood of the presence of cough, and its absence with an increased probability of the absence of asymmetric chest expansion and percussive sounds.

CONCLUSIONS

The comparison among populations with different diseases and carriers of the same nursing diagnosis shows that the predictive ability of clinical indicators can be influenced.
