I think there can be an overuse of medicines. Antibiotics in particular can sometimes be overused, especially for viral infections. There can be an inappropriate use of medicines as well. We just looked at every single patient in our hospital who had a fall from their bed, and we found that 60% were on Valium-type drugs. So there's a quality issue there. There can also be an underuse of medicines--in heart disease, diabetes, and so on.
I think many issues around the quality of medicines need to be addressed more systematically across the country.
