RESUMEN
PURPOSE: Prompt diagnosis of TB among adolescents may reduce transmission and improve individual outcomes. However, TB diagnosis in adolescents is challenging. This study sought to understand challenges to adolescent TB diagnosis. METHODS: We conducted qualitative focus group discussions (FGDs) to explore adolescents' and health workers' perspectives on challenges to TB diagnosis among adolescents seeking care at four secondary health care facilities in Uganda. Eight FGDs were conducted: four with 32 adolescents consulting for medical care and four with 34 health workers involved in TB care. RESULTS: Adolescents were aware of TB and associated risk factors and believed behaviours like smoking and alcohol use are risk factors for TB. They reported school schedules limit them from seeking TB care and have to miss school or wait for holidays to seek TB diagnosis. They noted school nurses do not take much interest in diagnosing TB and do not refer them to hospitals for further evaluation when they present with TB symptoms. Furthermore, adolescents reported cross-cutting issues like loss of trust in public health systems, encountering unfriendly, judgmental and uncooperative health workers. Health workers mentioned the school environment exposes adolescents to TB as the dormitories they sleep in are overcrowded. They indicated that it was difficult to make a diagnosis of TB in adolescents as the adolescents do not disclose health information. They reported fellow health workers perceive adolescents as being at low risk of TB as they believe most often adolescents are HIV negative and thus have reduced risk of TB. CONCLUSION: Adolescents present unique challenges that need to be addressed if TB diagnosis is to improve. These challenges could be handled by interventions that lead to minimal disruptions on school schedules, provision of adolescent-friendly services and intervention to build capacity of health care workers in the provision of adolescent-friendly services.
RESUMEN
BACKGROUND: Slow decline in the incidence of tuberculosis (TB) has been observed in most high TB burden countries. Knowledge of the prevalence of different TB risk factors can help expand TB control strategies. However with the exception of Human Immunodeficiency Virus (HIV) the prevalence of the other TB risk factors are poorly studied in Uganda. We aimed to determine the prevalence of different TB risk factors and TB disease presentation among TB patients in Kampala Uganda. METHODS: We assessed 365 adult TB patients and used descriptive statistics to summarize their socio-demographic, clinical, radiological, sputum mycobacteriology and TB risk factors (HIV, diabetes, TB contact, alcohol use, tobacco smoking, poverty and overcrowding) data. RESULTS: A total of 158 (43.3%) patients were male and the median age was 29 (IQR 28-30). Majority of the patients (89.2%) had pulmonary TB, 86.9% were new and 13.2% were retreatment. Wasting (i.e. body mass index of <18.5 kg/m(2)) was found in 38.5% of the patients and 63% presented with cough. Constitutional symptoms (fever, anorexia, night sweats and weight loss) were reported by 32.1%. Most patients (78.6%) presented with non-cavity lung parenchyma disease (infiltrates, nodules, masses) but 35.2% had cavity disease. Pleural disease was detected in 19.3% of patients. Positive smear microscopy and culture (irrespective of month of treatment) was found in 52.7% and 36.5% of patients respectively. Any drug resistance was detected in 21.1% of patients while multidrug resistance (MDR) TB defined as resistance to rifampicin and isoniazid was detected in 6.3% of patients. All MDR patients were new patients. The prevalence of TB risk factors were as follows: HIV 41.4%, diabetes 5.4%, close contact 11.5%, family history 17.5%, smoking 26.37%, poverty 39.5%, overcrowding 57.3% and alcohol use 50.7%. Overcrowding increased smear positive rate, prevalence ratio 1.22, p = 0.09 but all the other studied risk factors did not affect clinical, radiological and mycobacteriological study patient characteristics. CONCLUSIONS: Among TB patients in Kampala, Uganda, there is high prevalence of the known TB risk factors. Targeting reducing their prevalence may lead to better TB control in the country.
