OpAHSA has a very interesting and successful model for providing TB medications to people in India who would otherwise either not get medication or would not take their medications regularly. Not taking TB medication regularly leads to multi-drug resistant TB, which, when it spreads is an even bigger public health problem. Specifically OpASHA is able to check compliance with medication by using fingerprints to document that persons have shown up to take their medication and directly observating them taking their medication. Although very resource intensive, OpAHSA has local health workers who can go and find persons who do not show up to take their medications and then get their medications to them.
