Although the number of deceased organ donors in the United States has increased modestly since 2010 [1], a shortage of transplantable organs still remains. The dearth of available organs for transplantation is particularly acute among Latinx populations, an increasingly accepted and common term to represent Hispanic and Latino communities [2]. As of September 2019, over 23,000 Latinxs were candidates on the national transplant waitlist [3], of whom 88% were in need of a kidney transplant [4] because of higher rates of diabetes, chronic kidney disease, and end-stage renal disease compared with non-Hispanic whites. The need among older Latinxs is particularly acute. A large longitudinal study (n=453,162) of kidney transplant candidates showed that the proportion of Latinxs aged 45 years and older on the waitlist grew consistently from 56.4% during the 1995 to 1999 period to 69.8% in the 2010 to 2014 period [5]. Despite the need, only 1508 (14%) deceased organ donors were Latinxs in 2018 [6], although interest in and willingness to donate have been expressed within Latinx populations, including uninsured undocumented Latinx immigrants [7,8].

Since the 2007 revision of the Uniform Anatomical Gift Act making the act of registering as an posthumous organ donor legally binding [9], much like an advance directive or living will, it has become an even more critical first step to increasing the number of individuals converted to actual donors and the number of organs available for transplant. Currently, approximately half of the US population have designated themselves as posthumous organ donors through drivers’ licenses, donor cards, or Web-based registries—an act referred to as donor designation [10]. Donor designation rates among Latinxs have remained much lower than the national average. For instance, a retrospective cohort study of deceased donation decisions found that 6.4% of Latinx participants were designated organ donors [11], and a larger study (n=2070) found that less than 40% of Latinxs had documented their intentions to donate posthumously [12]. Although Latinxs in the United States come from various countries of origin and have distinct immigration histories, the extant literature describes this population as a homogeneous unit. Commonly cited barriers to donation among this population include low levels of acculturation, religious beliefs, mistrust of the medical and organ distribution systems, and cultural taboos regarding discussions about death [13-15]. Encouraging donor designation among all ethnic groups is imperative to improve access to transplantation for all patients on the waitlist. However, increasing the number of Latinx donors is of particular import, given the improved graft outcomes associated with receipt of organs from this subgroup of the population [16].

Prior research has underscored the importance of culturally targeted approaches to addressing the specific health beliefs and transplantation-related needs among Latinx communities. For example, Hu et al’s family-based intervention on diabetes self-management among Latinxs yielded successful outcomes, such as improved blood pressure, higher knowledge about diabetes, healthier behaviors, and lowered body mass index [17]. Gordon et al created and evaluated a culturally targeted website about living kidney donation and transplantation for Latinx patients; exposure to the website in combination with transplant education generated significantly higher transplant knowledge compared with transplant education alone [18]. Other research aimed at increasing organ donation among Latinx populations has suggested women as ideal champions for promoting donor designation, given their dominant position in health-related decision making and their increased willingness to donate and discuss donation with family members [14,19,20].

Promotores de Salud are a network of Latinx lay health educators (or community health workers) who disseminate health information to their communities through interpersonal channels. Indeed, platicas, or small group discussions typically held in homes or local community centers about different health topics, are organized and guided by promotores. In the 1960s, Promotores de Salud emerged out of necessity in low-income neighborhoods with sizable Latinx immigrant populations, to overcome significant barriers to accessing and utilizing health care services [21]. Promotores are a cost-efficient and effective workforce that expands the reach of the health care delivery system. As such, promotores have typically become the first point of contact between Latinx community members and formal health institutions. Given their knowledge of and membership in local and health care communities, promotores serve as cultural intermediaries, social/emotional supports, peer advocates, connections to available services, and catalysts for community action [22,23].

Promotores de Salud have had demonstrable impacts on health knowledge and behaviors. For instance, they have increased Latinxs’ knowledge of and participation in preventive behaviors for diabetes [24], cervical cancer [25,26], obesity [27,28], and cardiovascular disease [29]. Furthermore, a growing body of evidence suggests promotores can be effectively engaged in the research process and, once trained, can be successful partners in study implementation [30-35]. Promotores have been trained to provide culturally and linguistically appropriate information to Latinx Americans about a wide variety of health-related topics and to promote behaviors to improve health and prevent illness, disease, and disability [36,37]. As more than 80% of these community health workers are female [36] and older Latinxs are increasingly overrepresented on the national waitlist [5], we believed that this existing network of promotores could be leveraged to educate mature Latinas (aged 50 years and older) in their respective communities about organ donation. We also anticipated that mature Latinas would be influenced to designate themselves as posthumous organ donors and support donation within their families, as women are the primary source of information about health and health care in Latinx families. In addition, women, in particular, express greater willingness to register as deceased organ donors [14,19] and are more likely to register, be converted to actual donors, and discuss donation with their families [14,19,20].

Web-based electronic learning (eLearning) platforms (ie, learning management systems) are highly variable in their features and methods of instruction [38]. Such customizability allows developers to remain sensitive to the practical and cultural needs of the target audience and helps ensure ease of use and engagement with material. Interactive computer- and Web-based public health and patient education trainings [38,39] have successfully addressed the learning needs of older adults [40-42], underserved populations [18,43-48], and those with chronic communicable disease [49], especially when culturally informed [50]. Previous studies employing Web-based interventions with targeted features to effectively train promotoras have demonstrated that eLearning leads to wider reach [51] and impact in Latinx communities [52]. The Office of Minority Health (OMH) of the US Department of Health and Human Services’ creation and promotion of a Web-based training for promotoras about best practices for promoting health in their communities underscores this fact [53].

We developed the Promotoras de Donación Web-based eLearning module to increase promotoras’ knowledge of organ donation and transplantation and to improve their communication skills and confidence discussing and promoting organ donation with mature Latinas. The feminine form of the term promotor was chosen because most community health workers are female, as are our target audiences. The module is designed to increase rates of donor designation within Latinx communities across the United States and to ultimately reduce disparities in transplantation among Latinxs. This paper describes our development of the Promotoras de Donación eLearning module, including the formative work involved in the module’s development and the module’s theoretical underpinnings. We present the module design, structure, cultural foundations, the results of beta-testing, and the plan for modifying the module in response to the feedback received. The paper concludes with challenges to the development of the module; limitations; and plans to evaluate the module’s direct, indirect, and sustained effects.

Most beta-testers spoke Spanish and English equally at home (7/10) and identified as promotoras (6/10); the remaining 4 were leadership from the 4 partnering organizations. Most respondents somewhat or strongly agreed that the information presented was novel (7/10), felt the module activities helped them learn (9/10), enjoyed module activities (9/10), felt ready to teach others about organ donation and transplantation after viewing the module (8/10), would recommend this training to other promotoras (9/10), and felt the module was too long (6/10). Most respondents (9/10) agreed or strongly agreed that the module was free from stereotypes about the Latinx community, that the people in their community would believe the messages in the module were from credible sources, and that the messages in the module address commonly shared organ donation and organ transplantation myths in the Latinx community. Regarding website navigability, all respondents disagreed with the statement, “the website was too complex”; all respondents agreed or strongly agreed that the website was easy to use and that they liked the look and feel of the website. Most respondents (9/10) disagreed that the words, phrases, and expressions used in the module were too technical for the average promotora, and most respondents (8/10) agreed or strongly agreed that promotoras would find the website easy to use.

Half of the respondents (5/10) suggested removing the true/false activity, and 40% (4/10) of the respondents suggested removing the interview with a transplant expert. Most (8/10) respondents recommended definitely not removing the segments describing personal experiences with donation (mother of an organ donor) and transplantation (liver transplant recipient).

In addition to scale items, responses to open-ended questionnaire questions provided rich, contextualizing data suggesting improvements to the original module. Table 3 presents the qualitative questions and a selection of corresponding responses.

We gleaned several lessons from themes emerging from the open-ended responses. First, although beta-testers stated the module was informative and interactive, most found the module to be too lengthy and offered suggestions on content that could be shortened or edited out. Moreover, they noted that the most important messages of the module included life-saving opportunities of organ donation and the need for Latinx donors; they also liked the testimonials included in the module.

Promotoras de Donación is the first online training program about organ donation designed specifically for promotoras. We employed a rigorous process to develop this eLearning module. Specifically, following well-established guidelines, we incorporated findings from the extant literature research on organ donation beliefs among Latinx Americans, relied on established theories for guidance, and engaged promotoras and leadership from promotora organizations for advice and feedback throughout the process. As no research had yet examined the knowledge of and attitudes toward organ donation and transplantation or the act of donor designation among either promotoras or mature Latinas—our target audiences—we conducted a series of focus group interviews to elicit this information [74]. The findings of the group interviews were integrated in the design and content of the module. The result was the creation of an empirically and theoretically based, culturally and linguistically appropriate eLearning module designed through a collaborative partnership with promotoras and promotora organizations.

Beta-testing offered valuable feedback about user experience, acceptability, and content. To prepare the module for implementation and evaluation, we made several modifications. For example, we modified the module by increasing the font size for the true/false activity, enabling sensible advancement to subsequent sections for ease of module progression, including removing numbered sections on the menu bar, adding English subtitles, and disabling user manipulation of the progress bar. To reduce module length, we edited testimonials from the mother who had donated her deceased son’s organs and the transplant expert. We moved the animation depicting 3 ways to donate and the true/false activity to appear on the homepage after module completion as supplemental, rather than required material. After revisions, the Promotoras de Donación module lasts 1 hour, 3 min, and 38 seconds, with 7 min and 49 seconds of supplemental content. Table 4 provides a comparison of the original and final versions of the module.

The module is currently undergoing evaluation of its direct, indirect, and sustained effects. In the first phase of evaluation, we will recruit 40 promotoras (10 per partnering site) to complete the Promotoras de Donación module and associated pre- and postsurveys. The presurvey will be administered before participants are given access to the module, and the postsurvey will be administered upon module completion; both surveys have been translated into Spanish and will be administered online via Qualtrics. The surveys assess changes in organ donation knowledge and attitudes and confidence communicating about and promoting the act of donor designation.

After completing phase 1, the same promotoras will be invited to enroll in the second phase of the evaluation, conducted to test the indirect effects of the module on mature Latinas’ organ donation knowledge, attitudes, and intentions to register as posthumous organ donors. Specifically, trained promotoras will lead 2 platicas in their respective communities with up to 8 mature Latinas in each session. Before leading the platicas, participating promotoras will be apprised of the study protocols and trained in human subject’s protections. Promotoras will administer anonymous paper-pencil surveys to mature Latinas before beginning the discussion and before attendees leave the platica.

To measure the module’s sustained impact on promotoras’ organ donation knowledge and attitudes as well as communication confidence, participating promotoras will complete self-administered surveys before leading their first platica and after completing both. If the intervention demonstrates significantly increased rates of donor designation, our Web-based training will be disseminated widely to promotoras organizations across the United States and a petition will be made to the HHS OMH to include the module in its existing eLearning program for Promotores de Salud [53].

Several challenges arose in the development of Promotoras de Donación module. Reliance on multiple sources (ie, focus groups, partner organizations, and beta-testers) for input on module content and format increased module production and revision time frames. Although the feedback was critical to ensure the cultural appropriateness and relevance of the module for the target population, we underestimated the time needed to solicit, review, and incorporate feedback from every collaborating partner. Turnover in staff also contributed to the delays. Our original creative coordinator, who was a fluent Spanish speaker with advanced training in research, resigned necessitating the search for Spanish-speaking consultants in each state to facilitate the focus groups and analyze the resulting data. We also lost 2 study coordinators during critical periods of module development—the first was during finalization of the original version and the second was just before final modifications were made. Other researchers developing similar community-based eLearning interventions would do well to anticipate longer production timetables by adding 2 to 3 months before the launch of the intervention.

The decision to incorporate multiple sources of feedback on the module’s content also led to a longer overall running time than was originally planned. Although the final version of Promotoras de Donación was shortened by making original components supplemental, the module still lasts over 63 min in its final form with close to 8 min of supplemental material. This is considerably longer than initial plans of an approximately 20 to 30 min eLearning module. Even though we have yet to see if the increased length of the module will have any demonstrable impact on participant’s experience and satisfaction, the substantial increase in content required additional time for editing, additional hosting space to accommodate the size of media files, and troubleshooting with the Gift of Life Institute’s technological capabilities.

Promotoras de Donación is a novel, culturally targeted intervention firmly grounded in theory, extant literature, and formative research. In response to a lack of knowledge of organ donation and low willingness to register as a posthumous organ donor among Latinxs, the module aims to engender more favorable attitudes toward organ donation, improve knowledge levels, and build confidence discussing donor designation among promotoras as means of increasing registration rates within Latinx communities. The results of our beta-testing demonstrated strong user acceptability of the platform and the content. Furthermore, the module may be dispersed to Latinx communities across the nation at low cost and has considerable potential to increase the number of Latinx registered as deceased organ donors, thus helping to reduce the ongoing national shortage of transplantable organs.
