Pre-decannulation Peristomal Findings in Tracheostomized Cases and Their Effect on the Success of Decannulation

Development and validation of an online nomogram for predicting the outcome of open tracheotomy decannulation: a two-center retrospective analysis

BACKGROUND

Tracheotomy decannulation is critical for patients in the intensive care unit (ICU) to recover. In this study, we developed and validated an intuitive nomogram to predict the success rate of tracheotomy decannulation.

METHODS

We collected the data of 627 ICU patients before open tracheotomy decannulation from two medical institutions, including 466 patients (135 success and 331 failure) from the First Affiliated Hospital of Anhui Medical University as a training cohort, and 161 patients (57 success and 104 failure) from the Second Affiliated Hospital of Anhui Medical University as an external validation cohort. A least absolute shrinkage and multivariate logistic regression analysis were performed to determine the independent risk factors and construct the nomogram. The area under the receiver operating characteristic curve (AUC) was used to assess discrimination and the calibration plots were used to assess consistency. The clinical application was assessed using decision curve analysis and the clinical impact curve.

RESULTS

7 independent risk factors were eventually included in the prediction model. The AUC of the training cohort, internal validation and external validation were 0.932, 0.926, and 0.915, showing good discrimination. The model performed well in terms of calibration, decision curve analysis, and clinical impact curves. The superior performance of the model was also confirmed by external validation.

CONCLUSION

This nomogram can help ICU physicians identify high-risk patients for decannulation and plan their pre-decannulation treatment accordingly.

Factors associated with the occurrence of stomal stenosis after tracheostomy in adults

OBJECTIVE

Although tracheal stomal stenosis can be life-threatening, factors associated with the occurrence of stomal stenosis remain unknown. This study was performed to evaluate these factors in adult patients.

METHODS

We retrospectively identified adult patients who underwent tracheostomy from 2010 to 2016 using a Japanese national inpatient and outpatient database. We performed Cox proportional hazard regression analyses to evaluate factors associated with the occurrence of tracheal stomal stenosis.

RESULTS

We obtained data on 25,436 eligible patients. The proportion of tracheal stomal stenosis was 0.9%. Tracheal stomal stenosis was significantly less likely to occur in patients with regular use of oral steroids [hazard ratio (HR), 0.28; 95% confidence interval (CI), 0.09-0.88; P = 0.03] and in male patients (HR, 0.75; 95% CI, 0.57-0.97; P = 0.03). The occurrence of tracheal stomal stenosis was significantly associated with use of a mechanical ventilator at home (HR, 2.54; 95% CI, 1.55-4.15; P < 0.001) and a body mass index of <18.5 kg/m² (HR, 1.45; 95% CI, 1.06-1.99; P = 0.02).

CONCLUSION

Our study revealed several factors that are associated with tracheal stomal stenosis. These findings may help physicians to manage tracheal stomas.

Critérios para decanulação da traqueostomia: revisão de literatura

RESUMO Objetivo Realizar um levantamento bibliográfico a respeito da decanulação da traqueostomia para verificar os fatores e protocolos utilizados em estudos internacionais. Estratégia de pesquisa Estudo de revisão de literatura utilizando a base de dados PubMed com os descritores em língua inglesa “Tracheostomy”, “Weaning”, “Decannulation”, “Removal tube”, “Speech, Language and Hearing Sciences”, “Intensive Care Units”, “Dysphagia”, “Swallowing”, “Deglutition” e “Deglutition Disorders”. Critérios de seleção Estudos publicados nos últimos cinco anos (2012 a 2017), com população acima de 18 anos de idade; pesquisas realizadas somente com seres humanos; artigos publicados em língua inglesa; artigos com acesso completo irrestrito; pesquisas relacionadas aos objetivos do estudo. Análise dos dados foram analisados quanto aos seguintes itens: caracterização da amostra; profissionais envolvidos no processo da decanulação; etapas do processo de decanulação; tempo total em dias de uso da traqueostomia; tempo total em dias para concluir processo de decanulação; fatores de insucesso para conclusão do processo de decanulação. Resultados A maior parte da população estudada foi do gênero masculino e com alterações neurológicas. Dos profissionais envolvidos no processo de decanulação, participaram em ordem decrescente médicos, fonoaudiólogos, fisioterapeutas e enfermeiros. As etapas da decanulação mais citadas foram: avaliação da deglutição; treino de oclusão; avaliação da permeabilidade de passagem do ar; habilidade de manipulação de secreção e troca de cânula; desinsuflação do cuff e treino de tosse; uso de válvula de fala. Além disso, obtiveram-se dados a respeito do tempo total de traqueostomia e de decanulação. Conclusão A presença do fonoaudiólogo é extremamente importante no processo de decanulação, visto que a avaliação da deglutição foi a etapa mais citada nos estudos, sendo esse trabalho realizado em conjunto com médicos e fisioterapeutas.
