Clinical validation of the nursing diagnosis of ineffective protection in haemodialysis patients.

AIMS AND OBJECTIVES: To evaluate the clinical validity of indicators of the nursing diagnosis of "ineffective protection" in haemodialysis patients. BACKGROUND: Haemodialysis patients have reduced protection. Studies on the nursing diagnosis of "ineffective protection" are scarce in the literature. The use of indicators to diagnose "ineffective protection" could improve the care of haemodialysis patients. The clinical usefulness of the indicators requires clinical validation. DESIGN: This was a diagnostic accuracy study. METHOD: This study assessed a sample of 200 patients undergoing haemodialysis in a reference clinic for nephrology during the first half of 2015. Operational definitions were created for each clinical indicator based on concept analysis and content validation by experts for these indicators. Diagnostic accuracy measurement was performed with latent class analysis with randomised effects. RESULTS: The clinical indicator of "fatigue" had high sensitivity (p = .999) and specificity (p = 1.000) for the identification of "ineffective protection." Additionally, "maladaptive response to stress" (p = .711) and "coagulation change" (p = .653) were sensitive indicators. The main indicators that showed high specificity were "fever" (p = .987), "increased number of hospitalisations" (p = .911), "weakness" (p = .937), "infected vascular access" (p = .962) and "vascular access dysfunction" (p = .722). CONCLUSION: A set of nine clinical indicators of "ineffective protection" were accurate and statistically significant for haemodialysis patients. Three clinical indicators showed sensitivity, and six indicators showed specificity. RELEVANCE TO CLINICAL PRACTICE: Accurate measures for nursing diagnoses can help nurses confirm or rule out the probability of the occurrence of "ineffective protection" in patients undergoing haemodialysis.

Deficient knowledge in patients with heart failure: A study of diagnostic accuracy and etiological relationships.

PURPOSE: To evaluate the accuracy of defining characteristics and causal relationships of the etiological factors of the nursing diagnosis deficient knowledge in individuals with heart failure . DATA SOURCES: An analytical, cross-sectional study on the diagnostic accuracy of the defining characteristics and causal relationships of the etiological factors of the nursing diagnosis. The sample consisted of 140 patients with chronic HF and in outpatient follow-up. The latent class analysis method was used to test the accuracy of measurements and estimate the prevalence of the diagnosis. The calculation of subsequent probabilities and the odds ratio ( were also parameters employed. The study was approved by the Research Ethics Committee of the Federal University of Pernambuco. DATA SYNTHESIS: The diagnosis had an estimated prevalence of 38.57% in the sample. The inaccurate statements about the disease and/or therapy, self-care deficient performance, and inadequate behavior were the clinical indicators that best predicted the presence of the diagnosis and demonstrated the same sensitivity value (1.0000), specificity (1.0000), and 95% confidence interval (0.9999-1.0000) for all. The populations at risk was elderly (OR = 2.12, confidence interval 95% = 1.05-4.27), and illiterate individuals (OR = 2.07, confidence interval 95% = 1.03-4.16) had an approximately twofold great chance of developing havening deficient knowledge. CONCLUSION: The evaluation of the accuracy of clinical indicators, corresponding to the defining characteristics in the study, contributed to screening and diagnostic establishment capacity in clinical practice, and to the translation of theoretical and practical knowledge. IMPLICATIONS FOR NURSING PRACTICE: Accurate clinical indicators of the nursing diagnosis deficient knowledge facilitate the clinical reasoning of nurses and favor the professional's role in the development of health education strategies focused on the acquisition of knowledge about the disease by patients, family members, and caregivers.

FONTE DE DADOS: Estudo analítico, transversal, sobre a acurácia diagnóstica das características definidoras e relações causais dos fatores etiológicos do diagnóstico de enfermagem. A amostra foi composta por 140 pacientes com insuficiência cardíaca crônica e em acompanhamento ambulatorial. O método de análise de classes latentes foi utilizado para testar as medidas de acurácia e estimar a prevalência do diagnóstico. O cálculo de probabilidades posteriores e a Odds Ratio também foram parâmetros empregados. O estudo teve aprovação do Comitê de Ética em Pesquisa da Universidade Federal de Pernambuco. SÍNTESE DE DADOS: O diagnóstico apresentou prevalência estimada de 38,57% na população. As Declarações imprecisas sobre a doença e/ou terapêutica, Déficit no desempenho do autocuidado e Comportamento inadequado foram os indicadores clínicos que melhor predisseram a presença do diagnóstico e demonstraram o mesmo valor de sensibilidade (1.0000), especificidade (1.0000) e intervalo de confiança 95% (0.9999­1.0000) para todos. As populações em risco Idoso (Odds Ratio = 2.12, intervalo de confiança 95% = 1.05­4.27) e Indivíduos analfabetos (Odds Ratio = 2.07, intervalo de confiança 95% = 1.03­4.16) apresentaram, aproximadamente, duas vezes a chance de desenvolver o conhecimento deficiente. CONCLUSÃO: A avaliação da acurácia dos indicadores clínicos, correspondentes as características definidoras no estudo, contribuiu para a capacidade de triagem e estabelecimento de diagnósticos na prática clínica e para a tradução de conhecimentos teóricos e práticos. IMPLICAÇÕES PARA PRÁTICA DE ENFERMAGEM: Indicadores clínicos acurados do diagnóstico de enfermagem Conhecimento deficiente facilitam o raciocínio clínico do enfermeiro e favorecem a atuação do profissional na elaboração de estratégias de educação em saúde focadas na aquisição do conhecimento sobre a doença por parte de pacientes, familiares e cuidadores.

Middle range theory for the nursing phenomenon Ineffective social support network.

PURPOSE: To describe a middle range theory (MRT) with conceptual and explicative capacity of cause and effect situations of Ineffective social support network in nursing. DATA SOURCES: Descriptive study developed through the Lopes, Silva, and Herdman theoretical-causal validity method, using five steps for theory construction: definition of the approach for constructing the MRT, definition of the main concepts, development of the pictorial diagram, construction of propositions, and establishment of causal relationships and evidence for practice. The foundation of these steps and the development of a predictive nursing theory occurred through Sanicola's Social Network Theory combined with studies from an integrative literature review using the six steps proposed by Whittemore and Knafl. DATA SYNTHESIS-FINDINGS: The theory presents etiological factors and clinical indicators for Ineffective social support network, connecting situations related to the person, the members and the configuration of this network, and external situations. The pictogram, symbolically created, represents the hierarchical classification of proximal, intermediate, and distal etiological factors, and their relationship with clinical indicators. CONCLUSIONS: The MRT, predictive for the nursing phenomenon Ineffective social support network, provides understanding of the person from an interpersonal perspective, which interferes with and is affected by a network of virtues and vicissitudes, and has negative influences on health outcomes. Due to its practical vocation, this theory represents an advance in the science and praxis of nursing. IMPLICATIONS FOR CLINICAL PRACTICE: The findings of this study will contribute to the understanding of the nursing phenomenon Ineffective social support network and consequently support the identification of the nursing diagnosis Ineffective social support network, proposed for inclusion in the NANDA-I classification.

Effects of demographic and clinical character on differences in self-care behavior levels with arteriovenous fistula by hemodialysis patients: An ordinal logistic regression approach.

INTRODUCTION: Hemodialysis (HD) patients should be trained to develop self-care behaviors in order to prevent and preserve their arteriovenous fistula (AVF). The aim of this study was identifying the factors that affect the levels of self-care behavior with AVF by HD patients. METHODS: A cross-sectional study was conducted involving 89 patients. RESULTS: Self-care levels were negatively affected by patients' location (Azores) and positively affected by marital status, education, employment, AVF duration, and absence of complications with the AVF. Concerning the management of signs and symptoms, self-care levels were negatively affected by patients' location. Regarding prevention of complications, self-care levels were negatively affected by age and marital status and positively affected by marital status, employment, chronic kidney disease etiology, AVF duration, and previous AVF. CONCLUSION: Further studies are required in order to confirm whether the considered factors affect levels of self-care behaviors with AVF, or whether other factors are needed as well.

Self-care actions for the maintenance of the arteriovenous fistula: An integrative review.

OBJECTIVE: To identify self-care actions for the maintenance of arteriovenous fistula of renal patients. METHOD: An integrative review study was conducted and literature were searched in Medline/PubMed, Scopus, CINAHL, LILACS, BDENF and SciELO Library databases using the descriptors chronic renal insufficiency, arteriovenous fistula, self-care, and knowledge. The inclusion criteria were that the documents be written in Portuguese, English, and Spanish, full text available, published in the last five years, and that they address the research question. Reflection articles, theses, dissertations, editorials of non-scientific journals, and research studies that did not follow the necessary methodological rigor were excluded. Data were analyzed with the IRAMUTEQ software. RESULTS: Fifteen articles were selected and comprised the final sample. Seven classes of self-care actions emerged from the text segments analysis and grouped into three categories: 1) Self-care actions that maintain the arteriovenous fistula; 2) Self-care actions for the prevention and the monitoring of complications with arteriovenous fistula; 3) Self-care actions directed at the perioperative period of arteriovenous fistula preparation. CONCLUSION: The results allowed us to identify important care for the maintenance of arteriovenous fistula functionality. The self-care actions identified in this study can guide a nursing care policy for implementation with protocols that help identify problems related to self-care actions and, thus, subsidize the development of actions aimed at the renal patient. However, more studies with high levels of evidence that identify self-care actions with arteriovenous fistula and the factors involved in its implementation are needed.

Venous ulcer: risk factors and the Nursing Outcomes Classification.

OBJECTIVE: To explore the relationship between the risk factors for the development of venous ulcers and the indicators of tissue integrity from the Nursing Outcomes Classification. METHODOLOGY: A cross-sectional study conducted in 2013 in a university hospital in Natal/RN (Brazil). Fifty individuals selected by consecutive sampling participated in an interview and physical examination. RESULTS: The most important risk factors were: 44% presented with arterial hypertension, 26% allergy, 20% diabetes mellitus, 4% participated in some physical activity, 6% were smokers and 14% drank alcohol. There was a statistically significant association between diabetes mellitus and the texture of the lesion (p=0.015) and tissue perfusion (p=0.026); allergy and texture (p=0.034); physical activity and hydration (p = 0.034); smoking and thickness (p = 0.018); and alcoholism and exudate of the ulcer (p=0.045). CONCLUSION: . The relationship between risk factors and the nursing outcome indicators generated information relevant to the development of guidelines for the monitoring and treatment of venous ulcer information.
