ABSTRACT
BACKGROUND: Given India's high rate of TB, rising burden of non-communicable diseases (NCDs) and growing elderly population, elderly TB patients may be at higher risk of adverse outcomes including death, loss-to-follow-up (LTFU) and treatment failure. This may call for modifications in their management. This study thus aimed to compare the profile and treatment outcomes between elderly (≥60 years) and non-elderly (15-59 years) TB patients. METHODS: This was a retrospective cohort study using routinely-collected programme data from a chest clinic in Delhi, India. It included all elderly and selected non-elderly TB patients registered for treatment between 2005 and 2010. Data on patients' clinical and demographic characteristics and treatment outcomes were analysed. RESULTS: There were 812 elderly and 1624 non-elderly TB patients. Elderly patients were more likely to be male (63.2% vs 51.1%) and have smear-positive TB (56.0% vs 47.4%). Adverse outcomes were more frequent among elderly patients (adjusted OR 1.9, 95% CI: 1.5-2.4), specifically deaths (adjusted OR 5.0, 95% CI: 3.1-8.1) and lost-to-follow-up (adjusted OR 1.4, 95% CI: 1.0-1.9). CONCLUSIONS: The profile and worse outcomes of elderly Indian TB patients may be indicative of co-existing NCDs. This needs further investigation and likely calls for a more comprehensive and intensive approach to their management.
