Accuracy of the Defining Characteristics of the Nursing Diagnosis Hypothermia in Newborns.

PURPOSE: To analyze the accuracy of the defining characteristics of hypothermia in newborns and to verify associations between defining characteristics and clinical variables. METHODS: A cross-sectional accuracy study with statistical analysis. FINDINGS: Slow capillary refill, decrease in ventilation, peripheral vasoconstriction, and insufficient weight gain were the defining characteristics with the highest specificity values, while slow gastric emptying, skin cool to touch, irritability, and bradycardia were the defining characteristics with the highest values for both sensitivity and specificity. CONCLUSION: Slow gastric emptying, skin cool to touch, irritability, and bradycardia are good clinical indicators to infer initial stages of hypothermia and to confirm its presence. IMPLICATIONS FOR NURSING PRACTICE: Accuracy measures may contribute to the improvement of the diagnostic inferential process. OBJETIVO: Analisar acurácia das características definidoras de Hipotermia em recém-nascidos e identificar a associação delas com variáveis clínicas. MÉTODO: Estudo de acurácia transversal com análise estatística. RESULTADOS: Preenchimento capilar lento, diminuição da ventilação, vasoconstrição periférica e ganho de peso insuficiente apresentaram valores altos de especificidade enquanto esvaziamento gástrico lento, pele fria, irritabilidade e bradicardia apresentaram valores elevados de sensibilidade e especificidade. CONCLUSÃO: Esvaziamento gástrico lento, pele fria, irritabilidade e bradicardia são úteis para inferir estágios iniciais de hipotermia e para confirmação diagnóstica. IMPLICAÇÕES PARA PRÁTICA DE ENFERMAGEM: Medidas de acurácia podem contribuir para o processo de inferência do diagnóstico hipotermia.

Validation of Clinical Indicators of the Nursing Diagnosis of Ineffective Protection in Adolescents With Cancer.

PURPOSE: To validate the clinical indicators of the nursing diagnosis of Ineffective protection in adolescents with cancer based on diagnostic accuracy measurements. DESIGN AND METHODS: Measurements of sensitivity and specificity for the indicators were calculated using latent class analysis with random effects in a sample of 127 adolescents between 10 and 19 years of age. RESULTS: The prevalence of diagnosis was estimated at 93.7%. The indicators deficient immunity and weakness showed higher sensitivity values, whereas opportunistic infections, recurrent infections, insomnia, mucosal lesions, and coughing showed high specificity. CONCLUSIONS: Seven indicators were clinically validated. PRACTICE IMPLICATIONS: The validation of clinical indicators provides nurses with the knowledge of useful signs and symptoms to identify early spectra of a nursing diagnosis or confirm their presence in a specific population. In clinical practice, this knowledge contributes to an accurate diagnostic inference and the planning of nursing interventions directed to the idiosyncrasies of individuals.

Accuracy of the defining characteristics in nursing diagnoses of Hyperthermia in newborns / Precisión de las características definidoras del diagnóstico de enfermería Hipertermia en recién nascidos / Acurácia das características definidoras do diagnóstico de enfermagem Hipertermia em recém-nascidos

ABSTRACT Objective: to clinically validate the accuracy of the defining characteristics in nursing diagnoses of Hyperthermia in newborns. Method: a cross-sectional study conducted in units of medium and high risk in a maternity from the city of Fortaleza-CE. A total of 216 newborns were evaluated to identify the defining characteristics of diagnoses. A latent class model with random effects was used to measure sensitivity and specificity. Results: Hyperthermia was present in 5.6% of the sample. The characteristics lack of suction maintenance (31.3%); skin warm to touch (25.5%); lethargy (24.2%); and tachypnea (21.4%) were the most frequent. Stupor presented higher sensitivity (99.9%) and specificity (100%) while vasodilation characteristics, irritability and lethargy only showed significant values for specificity (92.7%, 91.6% and 74.3%, respectively). Conclusion: four characteristics of high specificity contribute to Hyperthemia. However, stupor is the only one with significant sensitivity to identify it at its early-stage.

RESUMEN Objetivo: validar clínicamente las características definidoras del diagnóstico de enfermería, Hipertermia en recién nascidos. Método: estudio transversal, realizado en las unidades de medio y alto riesgo de una maternidad ubicada en la ciudad de Fortaleza-CE. Fueron evaluados 216 recién nascidos para la identificación de las características definidoras del diagnóstico en estudio. Un modelo de clase latente con efectos aleatorios fue utilizado para establecer las medidas de sensibilidad y especificidad. Resultados: La Hipertermia estuvo presente en el 5,6% de la prueba. Las características en el Mantenimiento de la succión (el 31,3%); la Piel caliente al toque (el 25,5%); la Letargia (el 24,2%); y la Taquipnea (el 21,4%) fueron más frecuentes. La característica estupor presentó la mayor sensibilidad (el 99,9%) y la especificidad (el 100%), mientras que las características vasodilatación, irritabilidad y letargia, presentaron solamente los valores de especificidad significativos, respectivamente el 92,7%, el 91,6% y el 74,3%. Conclusión: La Hipertermia está relacionada a la presencia de las cuatro características con alta especificidad, mientras tanto, la característica estupor fue la única con sensibilidad significativa para identificación del diagnóstico en etapa inicial.

RESUMO Objetivo: validar clinicamente as características definidoras do diagnóstico de enfermagem, Hipertermia em recém-nascidos. Método: estudo transversal, realizado em unidades de médio e alto risco de uma maternidade localizada na cidade de Fortaleza-CE. Foram avaliados 216 recém-nascidos para a identificação das características definidoras do diagnóstico em estudo. Um modelo de classe latente com efeitos randômicos foi utilizado para estabelecer medidas de sensibilidade e especificidade. Resultados: a Hipertermia esteve presente em 5,6% da amostra. As características Não manutenção da sucção (31,3%); Pele quente ao toque (25,5%); Letargia (24,2%); e Taquipneia (21,4%) foram mais frequentes. A característica estupor apresentou maior sensibilidade (99,9%) e especificidade (100%), enquanto as características vasodilatação, irritabilidade e letargia, apresentaram apenas valores de especificidade significativos, respectivamente 92,7%, 91,6% e 74,3%. Conclusão: a Hipertermia está relacionada à presença das quatro características com alta especificidade, entretanto, a característica estupor foi a única com sensibilidade significativa para identificação do diagnóstico em estágio inicial.
