Abstract:
Introduction.
According to the updated national policy, the patients with
tuberculosis may benefit from the following treatment
options: 1. Community or home-based DOT when the
treatment is delivered in the community close to the
patients home or work.
2. DOT administered by specialized healthcare providers in
hospitals or specialized services.
3. Video-assisted treatment (VAT). VAT in patients with
pulmonary tuberculosis (TBP) involves monitoring of the
administration of the anti-tuberculosis drugs by a trained
medical worker using an electronic device.
Purpose.
To identify the barriers in implementation of VAT in
patients with PTB and to evaluate the therapeutic
outcomes.
Material and methods.
A prospective case-control study which included 114 patients with
PTB treated VA, distributed in the study group 1 (SG1) 26 cases
treated using the complete VA regimen and the study group 2 (SG2)
88 cases treated VA only in the continuation phase in the period
2019-2022 in Chisinau was conducted. Statistical analysis was
performed by SPSS Statistics 23.0 software, using Fisher exact test,
Odds Ratio (OR) and Confidence Interval (CI).
Results.
Distribution according to sex: men/women rate=1,4 in SG1 vs 2,7 in
SG2, and age between 18 and 44 years 15 (58%) vs. 61 (69%) cases,
respectively. Detected by symptomatic screening were 8 (31%) vs. 42
(48%), including 24 (92%) new cases vs. 82 (93%) and 2 (8%) vs. 6
(7%) relapses, respectively. The established risk factors were: socially
vulnerable status, OR=2.7 (CI95: 1.6-2.9); low level of education,
OR=2.5 (CI95: 1.8-3.4); vagrancy, OR=9.2 (CI95: 2.6-12.4); migration,
OR=3.5 (CI95: 2.4-4.2); comorbid state, OR=1.9 (CI95: 2.4-4.2).
Therapeutic success was established in 24 (92%) vs. 78 (89%) cases,
died 1 (2%) patient in SG1 and 1 (1.3%) continued the treatment in
SG1 vs. 10 (11%) in SG2.
Conclusions.
Barriers in implementation of VAT identified in patients with PTB
were: social risk factors, migration and comorbidities. The rate of
therapeutic success was high and similar in both groups.
