Accuracy of the defining characteristics of respiratory nursing diagnoses in patients with COVID-19.

OBJECTIVE: To analyze the accuracy of the defining characteristics of four respiratory nursing diagnoses (ND) in patients with COVID-19 and on oxygen therapy. METHODS: This is a cross-sectional study conducted in four Brazilian public hospitals in two regions of the country. A total of 474 patients with COVID-19 receiving oxygen therapy were assessed. Latent-adjusted class analysis with random effects was used to establish the sensitivity (Se) and specificity (Sp) of the defining characteristics evaluated for each ND. RESULTS: Among the ND that constituted the study (impaired spontaneous ventilatory, impaired gas exchange, ineffective airway clearance, and dysfunctional ventilatory weaning response), the following defining characteristics had the highest simultaneous Se and Sp (>0.8): decrease in tidal volume, confusion, irritability, dyspnea, decreased breath sounds, orthopnea, impaired ability to cooperate and respond to coaching, and decrease in the level of consciousness. CONCLUSIONS: Recognizing the clinical signs that predict respiratory ND in patients affected by COVID-19 can contribute to the nurse's accurate diagnostic inference and designate the appropriate nursing interventions to achieve the desired results and avoid complications.

OBJETIVO: Analisar a acurácia das características definidoras de quatro Diagnósticos de Enfermagem (DE) respiratórios em pacientes com COVID­19 e em uso de oxigenoterapia. MÉTODOS: Estudo transversal, realizado em quatro hospitais públicos brasileiros de duas regiões do país. Foram avaliados 474 pacientes diagnosticados com COVID­19 e em uso de oxigenoterapia. A análise de classe latente ajustada com efeitos randômicos foi utilizada para estabelecer a sensibilidade (Se) e especificidade (Sp) das características definidoras avaliadas para cada DE. RESULTADOS: As características definidoras volume corrente diminuído, confusão, irritabilidade, dispneia, sons respiratórios diminuídos, ortopneia, capacidade prejudicada para cooperar e responder orientações, e nível de consciência diminuído foram as que obtiveram maior sensibilidade e especificidade simultaneamente (> 0.8) dentre os diagnósticos de enfermagem compuseram o estudo: Ventilação espontânea prejudicada, Resposta disfuncional ao desmame, Desobstrução ineficaz das vias aéreas e Troca de gases prejudicada. CONCLUSÕES: Conhecer os sinais clínicos preditores dos diagnósticos de enfermagem respiratórios em pacientes acometidos por COVID­19 pode contribuir para a inferência diagnóstica acurada do enfermeiro e designar as intervenções de enfermagem apropriadas para atingir os resultados desejados e evitar complicações.

Evaluation of the effectiveness of nursing interventions in research from Brazilian postgraduation programs.

PURPOSE: The purpose of this study was to evaluate research from Brazilian postgraduate students who provide evidence of effectiveness for Nursing Interventions Classification (NIC). METHODS: We conducted a literature review study of thesis and dissertations available in the Brazilian Digital Library of Dissertations and Theses (D/T) in May 2021 regardless of the year they were conducted. In those studies that did not utilize the NIC in the effectiveness evaluation, the cross-mapping methodology was employed between NIC and the interventions used by the authors of the studies. RESULTS: Using a systematic process, we identified 91 studies. Twenty-seven met a priori inclusion and exclusion criteria. We found an increase in studies that focused on nursing interventions in the last 10 years (n = 19), a large proportion of clinical trials (n = 16), and the majority of articles from the Southeast region of Brazil (n = 20). The areas of focus were adult and elderly care, and with a special interest in the behavioral domain (n = 11). Two sensitivity criteria were identified in all D/T (n = 27), and each study presented evidence of effectiveness of a minimum of three criteria simultaneously. CONCLUSIONS: Based on the effectiveness criteria, the Brazilian scientific production in postgraduate programs carried out by nurses provides evidence of the effectiveness for NIC nursing interventions. IMPLICATIONS FOR NURSING PRACTICE: It is recommended to conduct further research that uses the NIC in the planning, conduct, and evaluation of interventions, based on effectiveness criteria of nursing sensitivity.
