Factors Affecting Death of New Pulmonary Tuberculosis Patients in Muang District, Lamphun Province, Fiscal Year 2018-2020

Abstract

A retrospective study was to determine factors affecting death of new pulmonary tuberculosis cases in Muang district, Lamphun province. Data collection recruited the new cases who registered for treatment between October 1, 2017–September 30, 2020 from the National Tuberculosis Information Program (NTIP) of the Tuberculosis Division, Department of Disease Control, Ministry of Public Health. A total of 213 patients had information on treatment from the start of treatment until the end. The study factors included sex, age, Body Mass Index (BMI), sputum smear grading at the register, HIV infection, and other comorbidities. Descriptive statistics analyses examined the general data while multiple logistic regression analyzed and determined the relationships between factors affecting death in the new cases of pulmonary tuberculosis. Results of the study found that risk factors for the dead cases included as follows: patients aged 50 and over  were 5.25 times more risk to death than who aged less than 50 (AOR=5.25, 95%CI=1.41-19.61), patients with sputum smear grading at the register 2+ and over were 8.92 times more risk of death than patients with initial sputum test result less than 2+ (AOR=8.92, 95%CI=2.19-27.74), and patients with cardiovascular/ cerebrovascular disease were 5.31 times more risk to death than those without that disease (AOR=5.31, 95%CI=1.62-17.40). Therefore, reduction of mortality is an obligatory death protection by closely monitoring and caring for the incident cases of pulmonary tuberculosis.
