Abstract
The adoption of new clinical practice patterns by medical care providers is often challenging, even when they are believed to be both efficacious and profitable. This paper uses a randomized field experiment to examine the effects of temporary financial incentives paid to medical care clinics for the initiation of prenatal care in the first trimester of pregnancy. The rate of early initiation of prenatal care was 34% higher in the treatment group than in the control group while the incentives were being paid, and this effect persisted at least 24 months or more after the incentives ended. These results are consistent with a model where the incentives enable providers to address the fixed costs of overcoming organizational inertia in innovation, and suggest that temporary incentives may be effective at motivating improvements in long run provider performance at a substantially lower cost than permanent incentives.

Interventions

Intervention(s)
Prior to the intervention period, the province paid facilities $40 ARS for each prenatal visit regardless of when it occurred or whether it was the first or a subsequent visit. During the intervention period the fee paid to treatment clinics was increased to $120 ARS for 1st visits that occurred before week 13, but remained at $40 ARS for subsequent visits. After that, the intervention period fees reverted to the original payment of $40 ARS for all visits. The modified fee structure was implemented for 8 months.

Experimental Design

Experimental Design
We test the effects of temporary incentives paid to clinics for early initiation of prenatal care using a field experiment conducted with Plan Nacer, in primary care clinics in the Province of Misiones. The experiment randomized temporary financial incentives to primary health care clinics in which treatment clinics were paid a 200% premium for early initiation of care.
Experimental Design Details
Randomization Method
Randomization was done simulating single random sampling in an excel sheet.
Randomization Unit
Clinics
Was the treatment clustered?
Yes

Experiment Characteristics

Sample size: planned number of clusters
37 clinics
Sample size: planned number of observations
Given that the number of women who visit a clinic can not be planned, and due to the small number of clusters in the experiment, the researchers did not plan for # of observations. Rather, they planed to conduct a series of robustness checks to ensure the achieved sample size held adequate statistical power.
Sample size (or number of clusters) by treatment arms
18 treatment clinics (modified fee schedule).
19 control clinics.
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
