Prevalence and Determinants of Non-Adherence to Anti-Tuberculosis Treatment Among Patients Receiving Tuberculosis Care in Southwestern Uganda
This cross-sectional study of 152 tuberculosis patients in southwestern Uganda reveals a 34.2% non-adherence rate driven primarily by forgetfulness, distance to facilities, side effects, and financial constraints, with HIV co-infection being a prevalent comorbidity among those missing doses.

Tuberculosis is an ancient bacterial infection that attacks the lungs, spreading through the air when a sick person coughs or speaks. While modern medicine has developed powerful drugs to cure the disease, the treatment is a marathon, not a sprint. Patients must take a combination of several different medicines every single day for at least six months. The success of this treatment depends entirely on the patient taking every dose exactly as prescribed. If a person stops early or misses doses, the bacteria can survive, multiply, and become resistant to the drugs, turning a curable illness into a deadly one. This problem of missing doses, known as non-adherence, is a major hurdle in the fight against tuberculosis, particularly in regions where resources are scarce and daily life is difficult.
In the southwestern part of Uganda, researchers set out to understand why patients were missing their medication. They focused their investigation on Ishaka Adventist Hospital, a private facility serving both city and rural communities in the Bushenyi District. The team interviewed 152 adult patients who had been undergoing treatment for at least three months. Instead of relying on guesswork, they used structured conversations and medical records to build a clear picture of who was struggling to stay on track and why. They looked at the patients' lives, their health conditions, and the challenges they faced getting to the clinic, hoping to find the specific barriers that caused people to skip their medicine.
The study revealed that missing doses was a common occurrence, affecting nearly one-third of the patients they surveyed. When the researchers asked these patients why they had skipped a dose, the answers pointed to a mix of daily life struggles and physical side effects. The most frequent reason given was simply forgetting to take the medicine, a problem that affected more than three-quarters of those who missed a dose. Beyond forgetfulness, the physical journey to the hospital was a significant obstacle; over one-third of the patients cited the long distance they had to travel as a reason for missing appointments. Other major hurdles included the side effects of the drugs themselves, the demands of a busy work schedule, and a lack of money to cover transport or other costs.
A striking finding emerged regarding the health of the patients. The vast majority of those in the study were also living with HIV, a virus that weakens the immune system and makes tuberculosis harder to fight. Among the patients who admitted to missing doses, nearly nine out of ten were co-infected with HIV. This suggests that managing two serious illnesses at once creates a heavy burden that can overwhelm even the most determined patient. The researchers also noted that many patients stopped taking their medication because they started to feel better before the treatment was finished, or because the side effects became too uncomfortable to bear.
Interestingly, the study found that a patient's background did not predict whether they would miss their medication. Factors such as age, gender, education level, job type, or religious belief showed no clear connection to adherence. Whether a patient was young or old, married or single, rich or poor, the likelihood of missing a dose remained the same. This suggests that the barriers to treatment are not tied to who a person is, but rather to the circumstances they face and the nature of the treatment itself. The data showed a direct link between the number of doses missed and the overall percentage of treatment completed, confirming that every missed pill chips away at the chance of a full cure.
The researchers concluded that solving this problem requires a multi-layered approach that addresses the specific hurdles patients face. Since forgetfulness is the leading cause of missed doses, simple reminders could help. However, because distance and money are also major factors, the health system needs to make it easier and cheaper for people to get their medicine. The high rate of co-infection with HIV indicates that doctors must provide integrated care that supports patients managing multiple conditions simultaneously. By focusing on these practical, everyday barriers rather than just blaming the patient, health workers in Uganda can help more people finish their treatment and stay healthy.
