“…The graph proposed by Bland-Altman was used, with the measures estimated and measured, to analyze agreement between them 15 . The limits of agreement are estimated by the mean difference (± 1.96), assuming that the differences are normally distributed 16 .…”

Objective: to evaluate methods of elderly height estimation attended at the Nutrition ambulatory. Method: a total of 43 elderly individuals of both genders were evaluated during nutrition consultations. Sociodemographic data were collected from charts and height, knee height, arms wingspan and semi-span were measured. Statistical analysis were made through Bland-Altman test to evaluate concordance among statures estimated by predictive formulas and the height measured. Results: the values found were: height measured in meters 1.53 (±0.08), height estimated by the wingspan 1.60 (±0.10), by the semi-span 1.61 (±0.11) and by the knee height 1.56 (±0.10). According to the Bland-Altman graph, the height estimated by knee height showed a better agreement with the measured height. Conclusion: according to this study results, poor predictive formulas concordance in height estimation in elderly, using the measures: arms wingspan and semi-span with real stature measured were observed. Knee height, using Chumlea formula, presented the best concordance with measured stature and seems to be a good way for stature estimation at the studied population.

“…Após a coleta, os dados foram digitados em planilha de Excel e analisados pelo Statistical Package the Social Sciences (SPSS) -versão 23. Para avaliar o grau de concordância entre os instrumentos de dependência foi obtida a concordância observada conforme proposto pelo índice de concordância de Kappa adotando o intervalo de confiança de 95% 14 .…”

O objetivo desta pesquisa foi analisar o grau de dependência de pacientes em uma Unidade de Recuperação Pós-Anestésica, comparando as necessidades de cuidados de enfermagem. Trata-se de um estudo quantitativo, transversal e descritivo. Dois instrumentos validados foram utilizados para classificar os pacientes de acordo com o grau de dependência e o índice Kappa para avaliar a concordância entre os instrumentos. Verificou-se uma prevalência na população masculina de 45 (64,3%), a especialidade médica mais atendida foi a neurocirurgia com 48 (68,6%). 65 pacientes (92,9%) foram geralmente classificados como graves e 59 (84%) a 60 (86%) que necessitaram de cuidados intensivos de enfermagem de acordo com os instrumentos que avaliam o grau de dependência. Conclui-se que o aumento da necessidade de cuidados depende inteiramente da gravidade do paciente e pode-se verificar que a faixa etária e os procedimentos invasivos realizados são variáveis que envolvem diretamente os cuidados prestados, uma vez que esses fatores contribuem diretamente para o aumento da o grau de dependência e duração da permanência no serviço de saúde.

“…However, researchers very often use them erroneously to test agreement of data or consecutive measures of the same phenomenon (for example, test-retest, 29 calibration of measurement instruments, interrater comparisons), even though there are more appropriate methods for these purposes. 30 Finally, strategies for evaluation of correlations between variables should be encouraged in clinical and biomedical research, since they maximize understanding of the phenomena studied. However, due to the peculiarities inherent to the different methods, they must be described in detail in the methodology and in the presentation of results.…”
