The study occurred in two stages, the first consisted of the evaluation of the diagnostic indicators in study; and the second, the diagnostic inference conducted by nurse diagnosticians. The first stage occurred from december 2012 to april 2013, in a University Hospital and a Hemodialysis Clinic in Northeastern of Brazil, with a sample of 100 chronic renal failure patients on hemodialysis. The data were selected through an interview form and a physical examination, organized into spreadsheets and analyzed as to the presence or absence of the indicators of diagnosis excessive fluid volume. In the second step, the spreadsheets were sent to three nurses diagnosticians, who judged the presence or absence of diagnosis in the clientele searched. This step was conducted from july to september 2013. For analysis of the data, we used descriptive and inferential statistics. In the descriptive analysis, we used measures of central tendency and dispersion. In inferential analysis, we used the tests Chi- square, Fisher and prevalence ratios. The accuracy of the clinical indicators pertaining to the diagnosis were measured as to the specificity, sensitivity, predictive values, likelihood ratios and Diagnostic Odds Ratio. Also developed a logistic regression. The results were organized in tables and discussed with literature. This study was approved by the Ethics Committee in Research of the Federal University of Rio Grande do Norte, with Presentation Certificate for Ethics Appreciation n? 08696212.7.0000.5537. The results revealed that the diagnosis studied was present in 82% of patients. The characteristics with prevalence above 50 % that stood out were: azotemia, decreased hematocrit, electrolyte imbalance, intake exceeds output, anxiety, edema, decreased hemoglobin, oliguria and blood pressure changes. Eight defining characteristics were presented statistically significant association with the nursing diagnosis investigated: pulmonary congestion, intake exceeds output, electrolytes imbalance, jugular vein distension, edema, weight gain over short period of time, agitation and adventitious breath sounds. Among these, the 10 characteristics which showed higher prevalence ratios were: edema and weight gain over short period of time. The features with the highest sensitivity were edema, electrolytes imbalance and intake exceeds output and the standing out with greater specificity were: anasarca, weight gain over short period of time, change in respiratory pattern, adventitious breath sounds, pulmonary congestion, agitation and jugular vein distension. The indicators jugular vein distension, electrolytes imbalance, intake exceeds output, increased central venous pressure and edema, together, were identified in the logistic regression model as the most significant predictors. It is concluded that the identification of accurate clinical indicators allow a good prediction of the nursing diagnosis of excessive fluid volume in patients undergoing hemodialysis in order to assist the nurse in the inference process, which will contribute to the success of patient care. In addition, nurses will consider for diagnostic inference not only his clinical experience, but also scientific evidence of the occurrence of excessive fluid volume, contributing to the control of volemia in these patients / Estudo transversal, com o objetivo de avaliar a acur?cia dos indicadores cl?nicos do diagn?stico de enfermagem Volume de l?quidos excessivo em pacientes submetidos ? hemodi?lise. Ocorreu em duas etapas, a primeira composta pela avalia??o dos indicadores do diagn?stico em estudo; e a segunda, pela infer?ncia diagn?stica realizada por enfermeiros diagnosticadores. A primeira etapa aconteceu nos meses de dezembro de 2012 a abril de 2013, em um Hospital Universit?rio e em uma Cl?nica de Hemodi?lise do Nordeste do Brasil, com uma amostra de 100 pacientes renais cr?nicos submetidos ? hemodi?lise. Os dados foram obtidos mediante formul?rio de entrevista e exame f?sico, organizados em planilhas eletr?nicas e analisados quanto ? presen?a ou aus?ncia dos indicadores do diagn?stico Volume de l?quidos excessivo. Na segunda etapa, as planilhas foram encaminhadas a tr?s diagnosticadores, que julgaram a presen?a ou aus?ncia do diagn?stico na clientela pesquisada. Essa etapa desenvolveu-se nos meses de julho a setembro de 2013. Para a an?lise dos dados, utilizou-se a estat?stica descritiva e inferencial. Na an?lise descritiva, utilizaram-se medidas de tend?ncia central e de dispers?o. Na inferencial, utilizaram-se os testes de Qui-quadrado, Fisher e as raz?es de preval?ncia. Mensurou-se a acur?cia dos indicadores cl?nicos do diagn?stico estudado por meio da especificidade, da sensibilidade, dos valores preditivos, das raz?es de verossimilhan?a e da Odds Ratio Diagn?stica. Desenvolveu-se tamb?m uma regress?o log?stica. Os resultados foram organizados em tabelas e discutidos com literatura pertinente. O estudo foi aprovado pelo Comit? de ?tica da Universidade Federal do Rio Grande do Norte, com Certificado de Apresenta??o para Aprecia??o ?tica n? 08696212.7.0000.5537. Os resultados revelaram que o diagn?stico de enfermagem estudado esteve presente em 82% dos pacientes. Dentre as caracter?sticas com preval?ncia acima de 50% destacaram-se: azotemia, hemat?crito diminu?do, eletr?litos alterados, ingest?o maior que o d?bito, ansiedade, edema, hemoglobina diminu?da, olig?ria e mudan?a na press?o arterial. 8 Apresentaram associa??o estatisticamente significativa com o diagn?stico de enfermagem investigado oito caracter?sticas definidoras: congest?o pulmonar, ingesta maior que o d?bito, eletr?litos alterados, distens?o da jugular, edema, ganho de peso em um curto per?odo de tempo, agita??o e ru?dos advent?cios. Dentre estas, as que apresentaram maiores raz?es de preval?ncia foram edema e ganho de peso em um curto per?odo de tempo. A caracter?stica com maior sensibilidade foi o edema e sobressa?ram-se com maior especificidade ru?dos advent?cios, congest?o pulmonar e agita??o. Os indicadores distens?o da jugular, eletr?litos alterados, ingesta maior que o d?bito, press?o venosa central aumentada e edema, em conjunto, foram identificados no modelo da regress?o como as caracter?sticas preditoras mais significantes. Conclui-se que a identifica??o de indicadores cl?nicos acurados permite uma boa predi??o do diagn?stico de enfermagem Volume de l?quidos excessivo em pacientes submetidos ? hemodi?lise, de modo a auxiliar no processo de infer?ncia do enfermeiro, o que contribuir? no sucesso do cuidado prestado ao paciente. Al?m disso, os enfermeiros considerar?o para a infer?ncia diagn?stica n?o apenas sua experi?ncia cl?nica, mas tamb?m evid?ncias cient?ficas da ocorr?ncia do Volume de l?quidos excessivo, contribuindo para o controle da volemia nesses pacientes
