Abstract

Background:

Tuberculosis (TB) is the ninth leading cause of death worldwide, and the leading cause of death from a single infectious agent prior to COVID-19 pandemic. TB substantially affects adults during their most productive years. However, all age groups are at risk. More than 25% of cases and deaths occur in Africa. People infected with HIV are 20-30 times more likely to develop active TB. In this study, we determined the level of TB medication adherence, risk factors and complications of TB in outpatients attending the Nsawam Government Hospital.

Method:

This cross-sectional study randomly recruited 277 patients with TB attending the Nsawam Government Hospital for care. Structured questionnaires were used to collect sociodemographic information, adherence and lifestyle characteristics. Associations and multivariate logistic regression analysis were performed with 95% CIs. All p<0.05 were considered statistically significant.

Results:

Majority (36.1%) of the patients were between the ages of 29 and 38. Majority (63.9%) of them had high adherence to TB medication. Participants earning less than 500 Ghana Cedis (Ghc) (adjusted OR (aOR)=8.85. 95% CI (1.59 to 49.24), p=0.013), patients with TB who indicated having complication (joint pain, spinal pain, heart disorders, liver or kidney problems) as a result of TB (aOR=2.81, 95% CI (1.58 to 4.99), p<0.001), respondents who mentioned living with people infected with TB (aOR=3.23. 95% CI (1.24 to 8.37), p=0.016) were the independent predictors of adherence to TB medication.

Conclusion:

The study findings revealed that participants exhibited commendable adherence to TB medication. Notably, adherence levels were found to be linked to several factors, including income, medication side effects and cohabitation with individuals infected with TB. The positive trend in adherence underscores the importance of considering socioeconomic factors, as lower income was identified as a potential barrier to consistent medication adherence.

Pulmonary Tuberculosis V

Pulmonary Tuberculosis V

Medical management of tuberculosis (TB) patients involves a comprehensive approach that includes diagnosis, treatment, and monitoring. The specific strategies can vary depending on the type of tuberculosis (latent or active), the patient's overall health status, and other considerations.
Latent tuberculosis infection occurs when TB bacteria are present in a person's body, but are not causing illness or symptoms. It is not contagious, and preventive treatment is crucial to avoid the...

Pulmonary Tuberculosis I

Pulmonary Tuberculosis I

Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
Mode of...

Pulmonary Tuberculosis IV

Pulmonary Tuberculosis IV

Tuberculosis, more commonly referred to as TB, is an infectious disease stemming from Mycobacterium tuberculosis. While it primarily impacts the lungs, TB can also affect other body areas. Given its severity and global impact, timely and accurate diagnosis is crucial for controlling its spread and improving patient outcomes.
Several diagnostic approaches are used to detect TB. The conventional method is the Tuberculin Skin Test (TST), also known as the Mantoux test. However, this method has...

Pulmonary Tuberculosis III

Pulmonary Tuberculosis III

Tuberculosis (TB) is a contagious infection primarily affecting the lung parenchyma but which can also affect other body parts. TB can be classified based on disease development, presentation, and the affected anatomical site.
The first classification is based on the development of the disease, and it includes the following categories:

Pulmonary Tuberculosis II

Pulmonary Tuberculosis II

Tuberculosis, or TB, is a bacterial infectious disease caused by Mycobacterium tuberculosis. While its primary impact is on the lungs, leading to pulmonary tuberculosis, it can also affect various other organs, a condition referred to as extrapulmonary tuberculosis.
Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...

Sputum Studies II: Culture and Sensitivity

Description
Sputum culture and sensitivity is a medical procedure used to diagnose bacterial infections in the respiratory tract and select the most appropriate antibiotics for treatment. This process involves analyzing sputum samples of thick and opaque secretions produced in the lungs and airways. These samples are collected from patients and then sent to the laboratory for analysis.
The test can identify various pathogens responsible for respiratory infections, including Streptococcus,...
