Assessment of Post-Treatment Health-Related Quality of Life among Patients with Pulmonary Tuberculosis in Ilorin, Nigeria.

ABSTRACT

BACKGROUND: A lot of attention has generally been given to the microbiology and treatment of pulmonary tuberculosis with relatively limited consideration on its impact on the physical, psychological and social domains of the individual especially after successful drug treatment. AIM AND OBJECTIVES: This study aimed at assessing the health-related quality of life (HRQoL) and related factors among individuals who had successfully completed treatment for pulmonary tuberculosis (PTB) in Ilorin. METHODS: This was a hospital based cross-sectional study at the pulmonary outpatient clinics of the University of Ilorin Teaching Hospital and Kwara State Specialist Hospital, Sobi, Ilorin. HRQoL assessment was conducted in 308 consenting patients who had been certified microbiologically cured for bacteriologically confirmed PTB in the preceding three years using the validated St. George's Respiratory Questionnaire (SGRQ). All subjects also had plain chest radiograph done for assessment of the presence and extent of lung parenchymal damage. RESULTS: The overall total median percentage HRQoL score was 18.5 (7.9-28.2) with the highest score in the activity component [33.7 (18.3-41.8)] and least scores in the impact component [10.0 (0.0-21.9)]. The independent predictors of impaired HRQoL were age > 40 years (p= 0.007), absence of formal education (p=0.004), mMRC score >1 (p= 0.002), PTB retreatment (p=<0.001) and radiographic scores >3 (p= <0.001). CONCLUSION: There is impaired HRQoL following treatment for PTB in Ilorin. Hence, there is a need to incorporate HRQOL assessment as an adjunct outcome measure after PTB treatment especially in those with the above identified risk factors.
