RESUMEN
Background: Various clinical applications have been attempted using artificial intelligence (AI) clinical decision support system (CDSS), and it has become a starting point for personalized cancer treatment. We aimed to identify the degree of agreement between the AI?CDSS, Watson for Oncology (WFO), and the clinician in treatment recommendations for Korean breast cancer patients and to provide guidelines for future improvement. Methods: One hundred and eighty?three breast cancer patients who underwent treatment at the Pusan National University Hospital between January 1, 2016 and May 31, 2017 were enrolled in this study. The concordance between WFO抯 and clinicians� treatment recommendations were examined according to various factors. Results: WFO gave the same treatment option recommendations as clinicians in 74 (40.4%) of the cases. According to the logistic regression, the difference in recommendation concordance between stage I and stage III was statistically significant (P = 0.004), and there was no difference among other factors. Conclusion: The concordance of treatment recommendations was low overall. However, this is largely attributable to the differences of medical insurance system and healthcare environment between the United States and Korea. In the future, region?specific features should be considered or reflected during the development of AI?CDSS.
RESUMEN
O significado prognóstico de vertigem em pacientes com perda auditiva neurossensorial súbita idiopática (PANSI) continua a ser uma questão controversa. OBJETIVO: Este trabalho tem como objetivo verificar a diferença entre um grupo com vertigem e um grupo sem vertigem e analisar a validação da vertigem como fator prognóstico em pacientes com PANSI. MÉTODO:Este estudo envolveu 183 pacientes com PANSI. O teste t foi utilizado para comparar o grupo A (PANSI com vertigem, n = 31) e o grupo B (PANSI sem vertigem, n = 152). Também queremos verificar os efeitos de interação entre vertigem e outros fatores prognósticos por meio de análise de regressão múltipla. RESULTADOS: Houve uma diferença significativa entre o grupo A e o grupo B: o nível auditivo inicial do grupo A foi menor do que no grupo B, e seu início de tratamento também foi menor. Além disso, a vertigem em si não afetou a melhora da audição, mas a variável de interação entre vertigem e nível de audição inicial afetou significativamente a melhora da audição. CONCLUSÃO: As características clínicas dos pacientes com vertigem não afetaram diretamente a melhora da audição de pacientes com PANSI; no entanto, vertigem teve uma influência sobre a PANSI por meio de sua interação com os níveis iniciais de audição.
The prognostic significance of vertigo in patients with idiopathic sudden sensorineural hearing loss (SSNHL) remains a matter of debate. OBJECTIVE: This paper aims to verify the difference between a group with vertigo and a group without vertigo, and to analyze vertigo's validation as a prognostic factor in patients with SSNHL. METHOD: This study involved 183 patients with SSNHL. A t-test was used to compare group A (SSNHL with vertigo, n = 31) and group B (SSNHL without vertigo, n = 152). Also we want to verify the interaction effects between vertigo and other prognostic factors using multiple regression analysis. RESULTS: There was a significant difference between group A and group B: the initial hearing level of group A was lower than group B, and their treatment onset was also shorter. In addition, vertigo itself didn't affect hearing improvement, but the interaction variable between vertigo and initial hearing level did affect hearing improvement significantly. CONCLUSION: The clinical characteristics of patients with vertigo did not directly affect hearing improvement with SSNHL; however, vertigo had an influence on SSNHL though its interaction with the initial hearing levels.
