Hi all
Some thoughts, more from low income setting perspective as this is what the article focused on.
to evaluate efficacy of cash transfers over another health intervention, an RCT would be needed, I think.
If one were to add cash transfer in the control arm of such RCT, participants in resource-limited settings could be more motivated to take part in the control arm, and this may hinder trial recruitment .
(this would not necessarily be the case in high income settings)
also, health interventions are often about embedding these into health systems if successful. can individual cash allocations contribute to effective health seeking in the absence of an appropriate underlying healthcare system and in settings where individuals may be driven to allocate this cash to other expenses?
Of course a lot depends on the study population, the setting, and the outcome being addressed. for instance in the HealthBudget programme, I can see how direct cash transfer can work for people who need long-term care and wish to organise it in an empowered manner according to the endpoints meaningful to them. It could also potentially work to modify the type of food consumed as a risk factor for NCDs assuming healthier food is more expensive, but here I think that a behavioural intervention in addition to cash would still be needed..
Best wishes
