New research has uncovered some surprising results in terms of what
motivates people living with HIV to adhere to their antiretroviral
therapy (ART) — and it isn’t cash alone. A recent study
based out of publicly-funded clinic in Atlanta Georgia showed that
people who chose to enter into a commitment contract to adhere to their
ART, in addition to receiving cash incentives, were more likely to
continue adherence and achieve viral suppression after the cash
incentives were stopped.
The participants, who were all patients that had detectable viral loads
despite at least six months on ART, were divided into three groups. In
the first two arms of the study, participants were given cash
incentives. The first arm of the study gave participants $30 for
attending scheduled provider visits. The people in the second arm were
given a choice between this first arrangement, or committing to a
contract that made the $30 payment conditional on both attending the
provider visits and meeting an ART adherence threshold. The third arm
participants were given regular care without cash incentives.
The study required participants to attend five provider visits. At the
time of the fifth scheduled visit and the last time the participants
would receive the cash payment, viral load results were not
significantly different. 42% of the people who entered into commitment
contracts had viral suppression, 38% of people who received incentives
for attending appointments had viral suppression, and 34% of individuals
who received no cash incentives were virally suppressed.
Now here’s where it gets interesting. Researchers surprised the
participants with a sixth, unscheduled visit three months after the cash
incentives had stopped. At this time, the results varied quite
significantly. 68% of patients in the adherence agreement arm were
virally suppressed, compared to 43% of patients in the appointment
incentive arm and 41% of patients in unpaid arm. The chances of viral
suppression did not differ much in the last two groups, however, the
patients who had entered into the adherence contracts were approximately
four times more likely to have viral suppression.
“Commitment contracts can improve ART adherence and virological suppression,” concluded the authors of the study, in a report by aidsmap.
The researchers theorized that because those who entered into the
commitment contracts chose to do so on their own, they had a greater
sense of personal empowerment in management of their condition.
