Severity and associated factors of anaemia among rifampicin/multi-drug-resistant tuberculosis patients treated in Alert and St. Peters specialised hospitals, Addis Ababa, Ethiopia: a retrospective cross-sectional study.

OBJECTIVE

To assess the severity of anaemia and associated factors among drug-resistant tuberculosis (DR-TB) patients treated in DR-TB treatment-initiating centers in Addis Ababa, Ethiopia.

DESIGN

A retrospective cross-sectional study.

SETTINGS

This study was conducted in Alert and St. Peters specialised hospitals, Addis Ababa, from 20 September to 15 October 2022.

METHODS AND ANALYSIS

Data was collected from 331 patients with DR-TB. The data was entered into Epi-Data 4.1, and SPSS version 25 was used for data cleaning and analysis. A multinomial logistic regression model was fitted after the multi-collinearity assumptions, and goodness-of-fit tests were done. The OR with 95% CI was reported for each outcome variable, taking normal haemoglobin level as a reference category. Variables with a P value of ˂0.05 were considered statistically significant.

RESULTS

Of the 331 patients, 51.4% had baseline anaemia, of which 5.7%, 15.7% and 29.9% had severe, moderate and mild anaemia, respectively.Patients who were urban residents (AOR: 0.06, 95% CI: 0.012, 0.32), government employees (AOR: 0.33, 95% CI: 0.001, 0.79), private job holders (AOR: 0.02, 95% CI: 0.001, 0.27), undernourished (AOR: 15.72, 95% CI: 2.46, 100.28), patients with HIV (AOR: 7.28, 95% CI: 1.627, 32.628) and farmers and students (AOR: 0.05, 95% CI: 0.004, 0.58) were significantly associated with severe anaemia.Patients who were male (AOR: 0.31, 95% CI: 0.11, 0.93), single (AOR: 0.19, 95% CI: 0.04, 0.85), daily labourer (AOR: 6.19, 95% CI: 1.27, 30.2), undernourished (AOR: 12.83, 95% CI: 4.88, 33.7) and patients with HIV (AOR: 12.74, 95% CI: 4.67, 34.75) were significantly associated with moderate anaemia. Patients with undernutrition (AOR: 3.92, 95% CI: 2.1, 7.35), HIV (AOR: 2.79, 95% CI: 1.22, 6.39) and primary and secondary education (AOR: 0.36, 95% CI: 0.17, 0.77) were significantly associated with mild anaemia.

CONCLUSION

In our study, more than 50% of patients with DR-TB had baseline anaemia, of which mild anaemia was the most common typeanaemia. Rural residents were at a higher risk of developing severe anaemia (11.5%), while the overall rate of anaemia (58.8%) was higher among urban residents.
