Evaluation de l'application des recommandations du Conseil Supérieur de la Santé relatives à l'isolement respiratoire des malades atteints de la tuberculose pulmonaire au CHU de Liège

The fight against tuberculosis is a public health objective at the world level. The prevention of the hospital-borne tuberculosis by an adequate isolation of the contagious patients is inescapable to eliminate the tuberculosis in Belgium. The Upper Council of the Health set up recommendations relative to the duration and the criteria of the isolation discontinuation. The objective of this study was to estimate the application of these recommendations at Liège University hospital and to determine factors associated to the long stay. The study includes 51 patients affected by pulmonary tuberculosis who were hospitalized in isolation wards within Pneumology department at the Liège University hospital on 1st January 2012 to 31st May 2017. The compliance to the recommendations was observed in 60.8 % and the main reason of the inadequacy of the practices was the isolation discontinuation before 3 negative sputum acid-fast bacilli smears results. The mean duration of isolation was 26.3 ± 19.9 days. Factors associated with the long stay were the high burden of bacilli on initial sputum smear examination (p < 0.001) and the antituberculous treatment delay (p = 0.03). © 2019 Revue Medicale de Liege.
