Treatment outcome and factors associated with success rate among adult patients with pulmonary tuberculosis at airborne infection clinic in King Chulalongkorn Memorial Hospital
Abstract:
Objectives: This research aims to study the success rate of adult patients with pulmonary tuberculosis treatment and factors associated with success rate among adult patients with pulmonary tuberculosis at Airborne Infection Clinic in King Chulalongkorn Memorial Hospital. Methods: A retrospective descriptive study in patients were treated at Airborne Infection Clinic in King Chulalongkorn Memorial Hospital during January 2018 to December 2020. The data were collected from patients medical records, data collection sheet, TB Register-03 book and KCMH_HIS program. Univariate and multivariate were analyzed by Binary logistics regression to identify factors associated with success rate of adult patients with pulmonary tuberculosis treatment. Results: There were 538 tuberculosis patients included in this study. There were 325 men (60.4%). The mean age and weight were 52.0 ± 31.0 years and 53.0 ± 14.8 kg. Most of them were drug-susceptible TB (87.2%) no previously treated TB (86.2%) and without HIV co-infection (93.3). Factors associated with success rate of adult patients with pulmonary tuberculosis treatment are age, weight, HIV infection and sputum AFB smear. The success rate of patients who are under 60 years old is 2.11 times higher than patients who are greater than or equal to 60 years old (ORadj = 2.11, 95%CI: 1.26 3.56). The success rate of patients who are over 40 kg is 2.46 times higher than patients who are less than or equal to 40 kg (ORadj = 2.46, 95%CI: 1.27 4.77). The success rate of patients without HIV co-infection is 5.84 times higher than patients with HIV co-infection (ORadj = 5.84, 95%CI: 2.62 - 13.05) and the success rate of patients who have sputum AFB smear negative is 2.06 times higher than patients who have sputum AFB smear 3+ (ORadj = 2.06, 95%CI: 1.06 3.97). Conclusions: The success rate of adult patients with pulmonary tuberculosis treatment at Airborne Infection Clinic was 82.9%. Factors associated with success rate of pulmonary tuberculosis treatment were age below 60 years, weight over 40 kg, patients without HIV co-infection and patients with sputum AFB smear negative.
