Translation, cross-cultural adaptation, content validation, and clinical feasibility of the nutritional pathway for infants with congenital heart disease before surgery

Abstract

Objective:

The aim of this study is to translate and validate the Nutritional Pathway for Infants with Congenital Heart Disease before Surgery British nutritional protocol into Brazilian Portuguese and test its clinical feasibility for specialized clinicians in Brazilian hospitals.

Method:

The translation and validation process followed strict methodological standards over the following steps: 1) initial translation; 2) synthesis; 3) back-translation; 4) expert committee content validation, and pre-test clinical feasibility with 30 health professionals. Data were collected through the Research Electronic Data Capture software data system, and then extracted and analyzed through statistical analysis software.

Results:

The culturally adapted version was considered equivalent to the original. In the first round, 82% agreement was achieved, and after consensus, there was 100% agreement among the experts. Regarding the ease of use of the protocol in clinical practice, the instrument obtained a minimum agreement rate of 93.4% and a 0.92 content validity index.

Conclusions:

The results indicate that the instrument adapted to Brazilian Portuguese has high content validity, and high reliability among the experts, suggesting a high level of accuracy of the instrument and cultural adaptation for Brazilian culture and medical systems. It was easily understandable by health professionals, as well as simple to apply in clinical practice. The Nutritional protocol for preoperative infants with congenital heart disease can reproduce the outcomes found in the pilot of this instrument carried out in the United Kingdom, which may promote better pre-surgical nutritional status for infants with congenital heart disease in Brazil.
