Abstract

Background The early identification of risk for dysphagia in patients with Parkinson's disease (PD) is essential for the prevention of nutritional and pulmonary complications.

Objective To analyze the sensitivity and specificity of the Swallowing Disturbance Questionnaire (SDQ-PD) and the Eating Assessment Tool (EAT-10) in identifying dysphagia risk in patients with early and intermediate stages of PD.

Methods Twenty-nine patients with PD participated in the study. EAT-10 and SDQ-PD questionnaires were applied, and a videofluoroscopic swallowing study. Dysphagia Outcome and Severity Scale (DOSS) was used to classify the presence and severity of dysphagia, and the Penetration-Aspiration Scale (PAS) was used to identify the presence of penetration/aspiration. In the statistical analysis, the sensitivity and specificity of the risk questionnaires were calculated, as well as positive predictive value, negative predictive value, and accuracy.

Results EAT-10 to identify the risk of penetration/aspiration revealed a sensitivity of 71.42% and specificity of 45.45%; in the identification of the presence of dysphagia, the sensitivity was 47.61%, and the specificity was 12.5%. The SDQ-PD questionnaire for risk of penetration/aspiration demonstrated a sensitivity of 28.57%, and a specificity of 68.18%. In terms of identifying the presence of dysphagia, the sensitivity was 20%, while the specificity was 44.44%.

Conclusion The SDQ-PD revealed low sensitivity and low specificity to identify the presence of dysphagia and/or penetration/aspiration in patients with early and intermediate stages of PD in this sample. Despite its low specificity, the EAT-10 exhibited good sensitivity in indicating the risk of penetration/aspiration.

Resumo

Antecedentes A identificação precoce de risco para disfagia nos pacientes com doença de Parkinson (DP) é fundamental para a prevenção de complicações nutricionais e pulmonares.

Objetivo Analisar a sensibilidade e especificidade dos questionários Swallowing Disturbance Questionnaire (SDQ-PD) e Eating Assessment Tool (EAT-10) para a identificação do risco de disfagia em pacientes com DP nos estágios iniciais e intermediários da doença.

Métodos Participaram 29 pacientes com DP. Foi realizado a aplicação dos questionários EAT-10 e SDQ-PD e o exame de videofluoroscopia da deglutição. Para a classificação da presença e gravidade da disfagia foi utilizada a escala Dysphagia Outcome and Severity Scale e, para identificação da presença de penetração/aspiração, a escala Penetration-Aspiration Scale (PAS). Na análise estatística, calcularam-se a sensibilidade e a especificidade dos questionários de risco EAT-10 e SDQ-DP e o valor preditivo positivo, o valor preditivo negativo e a acurácia.

Resultados A análise do EAT-10 para identificar o risco de penetração/aspiração revelou sensibilidade de 71.42% e especificidade de 45.45%; para identificar a presença de disfagia, a sensibilidade foi de 47,61% e a especificidade de 12.5%. Em relação ao questionário SDQ-PD, para identificar risco de penetração/aspiração, a sensibilidade foi de 28.57% e a especificidade de 68.18% e, para identificar a presença de disfagia, a sensibilidade foi de 20% e a especificidade de 44.44%.

Conclusão O questionário SDQ-PD revelou baixa sensibilidade e baixa especificidade para identificar presença de disfagia e/ou penetração/aspiração em pacientes com DP em estágios iniciais e intermediários para essa amostra. O EAT-10 revelou boa sensibilidade na indicação de risco de penetração/aspiração, apesar de baixa especificidade.
