Background

Latinx populations are severely underrepresented among organ donors compared with the non-Hispanic White population. The Promotoras de Donación e-learning module was developed to train Latinx lay health educators (ie, promotoras) to discuss deceased organ donation and promote donor designation within their communities.

Objective

This paper described the results of 2 studies designed to assess the direct and indirect effects of the module on promotoras’ and mature Latinas’ organ donation and donor designation knowledge, attitudes, and behaviors.

Methods

In partnership with 4 community-based promotoras organizations, we designed 2 nonrandomized, quasiexperimental pragmatic studies to evaluate the Promotoras de Donación e-learning module, with participating promotoras and mature Latinas serving as their own controls. Brief surveys were administered to participating promotoras before and after module completion to assess changes in organ donation knowledge and support and communication confidence (study 1). Promotoras participating in the first study were asked to hold at least 2 group conversations about organ donation and donor designation with mature Latinas (study 2); paper-pencil surveys were completed by all participants before and after the group conversations. Descriptive statistics, means and SDs, and counts and percentages were used as appropriate to categorize the samples. Paired sample 2-tailed t test was used to assess changes in knowledge of and support for organ donation and confidence in discussing donation and promoting donor designation from pre- to posttest.

Results

Overall, 40 promotoras completed this module (study 1). Increases in organ donation knowledge (mean 6.0, SD 1.9 to mean 6.2, SD 2.9) and support (mean 3.4, SD 0.9 to mean 3.6, SD 0.9) were observed from pre- to posttest; however, these changes did not reach statistical significance. A statistically significant increase in communication confidence was found (mean 692.1, SD 232.4 to mean 852.3, SD 139.7; P=.01). The module was well received, with most participants deeming it well organized, presenting new information, and providing realistic and helpful portrayals of donation conversations. A total of 52 group discussions with 375 attendees were led by 25 promotoras (study 2). The trained promotora-led group discussions about organ donation resulted in increased support for organ donation in promotoras and mature Latinas from pre- to posttest. Knowledge of the steps to become an organ donor and belief that the process is easy to perform increased in mature Latinas from pre- to posttest by 30.7% and 15.2%, respectively. In total, 5.6% (21/375) of attendees submitted completed organ donation registration forms.

Conclusions

This evaluation provides preliminary support for the module’s direct and indirect effects on organ donation knowledge, attitudes, and behaviors. The need for additional modifications to and future evaluations of the module are discussed.
