Nurses' knowledge regarding the handling of the totally-implanted venous access device

Construction and validation of a checklist for the management of totally implanted catheters in children

OBJECTIVES

to construct and validate the content of a checklist for the management of totally implanted catheters in hospitalized children and adolescents.

METHODS

methodological research conducted from October 2021 to December 2022 in two stages: development of the instrument with care guidelines and content validation of the checklist. The instrument, containing 23 items presented in Likert format, was evaluated online by specialists in two rounds. The Content Validity Index was applied, considering indices above 0.8 as valid.

RESULTS

the final checklist included four domains and 22 checklist items, validated with a Content Validity Index of 0.98. The overall evaluation of the instrument presented a global score of 9.9.

CONCLUSIONS

the validation and application of instruments that standardize procedures, in addition to supporting professionals, promote autonomy and quality of care for children and adolescents using this device.

Construction and validation of a mobile application for development of nursing history and diagnosis

OBJECTIVES

to describe the construction and validation process for a mobile application for development of the nursing history and diagnosis.

METHODS

methodological study conducted in 2018 in three stages: content creation, based on the Basic Human Needs categories and nursing diagnoses; content assessment by nine nursing judges, with calculation of the content validity index; and construction of the application, which included definition of the requirements, a conceptual map, implementation and prototyping options, tests and implementation.

RESULTS

the application was organized by sections: Grouped Basic Human Needs, Cranial pair tests, Clinical assessment scales and Additional tests. Two section were adjusted according to the judges' suggestions.

FINAL CONSIDERATIONS

it is the first application produced in Brazil based on the Basic Human Need categories, which enables quick access to information, concepts and typical nomenclatures of semiology, recording of clinical data and definition of nursing diagnoses.

Dosage of heparin for patency of the totally implanted central venous catheter in cancer patients

OBJECTIVE

to analyze the evidence available in the literature about the lowest necessary dose of heparin to maintain the patency of the totally implanted central venous catheter in adult cancer patients.

METHOD

an integrative literature review, carried out in the following databases: Literatura Latino-Americana e do Caribe em Ciências de Saúde, Sciverse Scopus, Web of Science, Cumulative Index to Nursing and Allied Health Literature, Cochrane Central Register of Controlled Trials, including thirteen studies.

RESULTS

the evidence showed that the dose of heparin (300 IU/ml) is the most used in maintaining the patency of the totally implanted central venous catheter.

CONCLUSION

according to the selected studies, the lowest dose of heparin found in maintaining the patency of the totally implanted central venous catheter in cancer patients was 10 UN/ml with a volume of 5 ml of the heparin solution.

Validation of a questionnaire of knowledge and attitudes about the subcutaneous venous reservoir in nursing

Objective:

design and validate a questionnaire to evaluate the knowledge and attitudes of nurses about the subcutaneous venous reservoir.

Method:

pilot test: 30 specialized care nurses. Main study: 236 nurses of primary and specialized care. Content validity was evaluated by Lawshe index, reliability by test-retest, internal consistency by Cronbach alpha, and construct validity by exploratory factorial analysis.

Results:

Items with a Lawshe index lower than 0.51 were eliminated. In the test-retest, the intraclass correlation coefficient was higher than 0.75 for all items. The Cronbach alpha of the attitude questionnaire reached 0.865. The Cronbach alpha value for knowledge was 0.750. The exploratory factor analysis identified a set of four dimensions for each part that explain 64% (attitude) to 80% (knowledge) of variability.

Conclusion:

the analysis of the reliability and validity of the questionnaire supports its use as an instrument to assess the knowledge and attitudes of nurses towards the subcutaneous venous reservoir.
