Every new health technology will impact on inequities one way or another – either increase, decrease or help maintain. It depends on what the HT is used for – does it address the needs of the most marginalised or is it used to help treat the problems faced by the white worried well? If it does address the needs of both marginalised and non-marginalised populations – who benefits most? I suggest you look at a health impact assessment – the New Zealand Whanau Ora HIA is a good place to start.
I strongly believe that HIT will impact health disparity, think of delivery of faster service and introduction of web access to doctors serving the population in remote communities. This will be a start.
I am in South Africa and here, even the poorest people living in rural regions have mobile phones. Mobile phone technology is a key strategy in increasing access.
