| Summary: | The study is a randomized controlled
trial that investigates the impact of four demand-side
interventions on health screening for diabetes and
hypertension among Armenian adults ages 35-68 who had not
been tested in the last 12 months. The interventions are
personal invitations from a physician (intervention group
1), personal invitations with information about peer
screening behavior (intervention group 2), a labeled but
unconditional cash transfer in the form of a pharmacy
voucher (intervention group 3), and a conditional cash
transfer in the form of a pharmacy voucher (intervention
group 4). Compared with the control group in which only 3.5
percent of participants went for both screenings during the
study period, interventions 1 to 3 led to a significant
increase in the screening rate of about 15 percentage points
among participants. The highest intervention impact was
measured among recipients in intervention group 4, whose
uptake of screening on both tests increased by 31.2
percentage points. The levels of cost-effectiveness of
intervention groups 1, 2, and 4 are similar while for
intervention group 3 it is about twice more expensive per
additional person screened. |
