ABSTRACT Objective: To analyze the time elapsed between the identification of respiratory symptoms and the beginning of tuberculosis treatment, considering the sputum smear microscopy and the RMT. Method: Descriptive, retrospective epidemiological study, carried out in two Health Units, which were the only units that performed diagnosis by sputum smear microscopy and Rapid Molecular Test in the city. Data on respiratory symptoms with a positive result for tuberculosis were used. Analysis of data distribution and variance was performed, with a significance level of 5%. Results: The longest time interval found was “result/beginning of treatment”, for both tests, with a median of 3 days. It was found that the patient takes longer to receive the result when performing the Rapid Molecular Test. Conclusion: Patients who had the Rapid Molecular Test waited longer for results when compared to sputum smear microscopy, leading to a reflection on the need for further studies on the operation of health services.

ABSTRACT Objective: To evaluate the impact of the use of the molecular test for Mycobacterium tuberculosis and its resistance to rifampin (Xpert MTB/RIF), under routine conditions, at a referral hospital in the Brazilian state of Bahia. Methods: This was a descriptive study using the database of the Mycobacteriology Laboratory of the Octávio Mangabeira Specialized Hospital, in the city of Salvador, and georeferencing software. We evaluated 3,877 sputum samples collected from symptomatic respiratory patients, under routine conditions, between June of 2014 and March of 2015. All of the samples were submitted to sputum smear microscopy and the Xpert MTB/RIF test. Patients were stratified by gender, age, and geolocation. Results: Among the 3,877 sputum samples evaluated, the Xpert MTB/RIF test detected M. tuberculosis in 678 (17.5%), of which 60 (8.8%) showed resistance to rifampin. The Xpert MTB/RIF test detected M. tuberculosis in 254 patients who tested negative for sputum smear microscopy, thus increasing the diagnostic power by 59.9%. Conclusions: The use of the Xpert MTB/RIF test, under routine conditions, significantly increased the detection of cases of tuberculosis among sputum smear-negative patients.

ABSTRACT Objective: to analyze factors associated with unfavorable outcome of tuberculosis treatment in people deprived of liberty. Method: systematic review, carried out in March 2021 in seven databases, with no delimitation of period of publication. The selection process of publications and data extraction was carried out by two independent reviewers. Results: a total of 1,448 publications was identified and nine were included in the study. Unfavorable outcome was higher among those who were men; had low level of education; were living in a rural area before detention; had longer prison time; received occasional visits; had been transferred between prisons; with no sputum smear microscopy or with a positive result at the diagnosis; with no follow-up sputum smear microscopy, previous history of tuberculosis; having both clinical forms of the disease, HIV/AIDS; alcoholics; smokers; low body weight; and self-administered treatment. Treatment default was associated with young people and death with older people. Conclusion: prison health managers and professionals are expected to establish mechanisms of surveillance and health actions innovation aimed at the population deprived of liberty, making efforts to reduce the unfavorable outcomes of tuberculosis treatment.

Smear Positive Pulmonary Tuberculosis

Background. Prolonged laboratory diagnostic process of tuberculosis can lead to failure to complete the diagnosis and increase dropout rate of smear positive pulmonary tuberculosis (PTB) cases. This implies such dropout patients without completing diagnosis are critical as infected individuals remain untreated in the community, providing more opportunities for transmission of the disease and adversely affecting the epidemic. The aim of this research is to determine the level of smear positive PTB diagnosis dropout rate of spot-morning-spot sputum microscopy diagnosis method in public health facilities, in Addis Ababa, Ethiopia. Methods. Retrospective review of patient documents in 13 public health facilities’ TB laboratory in Addis Ababa was conducted from October 2011 to March 2016. Data was computerized using Epi-info software and analysed using SPSS version 20.0 software. Descriptive numerical summaries were used to present the findings. Association between the dropout rate and demographic variables was assessed by Chi-square (X2). Bivariate model using Odds Ratio (OR) with a 95% Confidence Interval (CI) was calculated. P-Value less than 0.05 was taken as statistically significant. Results. Of 41,884 presumptive TB patients registered during the 53 months for laboratory investigation, 5.9% were positive for the first spot sputum smear microscopy. Among these positive cases, 142 (5.8%) and 298 (12.1%) did not come back to the laboratory to submitted early morning and second spot sputum specimens, respectively. The diagnostic dropout for morning sputum specimen in hospitals was 5.6% (58/1039) and in health centres was 5.9% (84/1424). However, higher proportion of dropout for second spot sputum specimen in hospitals was 16.4% (170/1039), compared to the health centres, 8.9% (128/1424). Diagnostic dropout of sputum smear microscopy had no significant association with sociodemographic variable (P value >0.05), while it had significant association with facility type (P value <0.05). Conclusion. In this study smear positive pulmonary tuberculosis diagnostic dropout rate was high compared to WHO reported for the new strategy shift implying the importance of shifting to same-day approach. Hence, shifting from conventional to same day is crucial to minimize the TB diagnostic dropout rate in the study area and other similar settings. Further research is needed/recommended in the local setting to compare the yield and dropout rates between same-day and conventional sputum smear microscopy approach.
