This study has provided important insight on the feasibility of digital health learning in Ethiopia. The majority of the study participants had a positive attitude towards blended learning, and have expressed their readiness to pay a modest amount of money if asked to do so. The use of mobile phone by almost all of the study participants, the larger Internet connectivity with their mobile, and the high interest in digital learning among those who had the experience may indicate the competitive and comparative advantage of digital learning in this digital era/information age. After an extensive literature review, the WHO has also noted the potential of digital learning to improve the competencies and satisfaction of health workers. However, its effectiveness and outcomes may be influenced by several factors, including the digital learning modality (mobile phones, online digital learning, virtual reality, or others), delivery mode (blended or fully digital)7, learner’s characteristics (including self-regulated skills in operating and using applications) as one of the predictors for effectiveness of blended learning.17
Previous authors have as well noted that the unprecedented mobile service utilization and the increasing interconnectedness through Internet is opening room for the digital learning, and probably evolving to change the modality of future education.18 For low-income countries, earlier prediction by Poushter J was as “smartphone ownership and internet usage continues to climb in emerging economies”,19 which is in line with the current finding. The rising demand for smart phone and mobile Internet users in Ethiopia (in 2020, 41% of the population having mobile connection with 19% Internet connection)20,21 is encouraging to plan the m-learning for training and m-health for the population at large. Local and international literature review has shown the potentially effective and financially scalable solutions to digitalize health workforce trainings, including m-learning and blended digital learning (with comparative advantages for both pre-and in-service trainings).7,11,22,23
However, as the key informants pointed out, the healthcare workers’ ability to function with the electronic devices may be a critical factor. If they are not provided training on how to use their phones for digital learning purpose for those with limited skills, they may lag behind or drop the training. 17 The frequent electric power interruptions, political turmoil, and the limited experience of higher educations in leveraging digital devices are key challenges for scaling up digital learning in Ethiopia.
Apart from the unaffordability of laptops/desktops and broadband by all, the high utilization of smartphone for Internet access by most of the study participants may be explained by its easier portability. Certainly, it was already noted that there is a growing interest and practice in smartphone to get access to Internet, even in the developed world,24 probably because of its easier access to operate and portability. In essence, apart from its day to day use for information exchange, the growing number and interest in using smartphone could be considered as a fertile ground for the m-health market (in a broader sense), as it enables delivering and receiving both formal (credited) and informal education.
The familiarity of the study participants with the mobile technology is another important indicator for the success of digital learning if gets implemented in larger scale; based on earlier studies, it was noted that a learner with difficulty of using the digital technology is likely to abandon it; develops negative attitude; and eventually fails to complete the course.25,26 Literature review has also shown that health professional skills are better improved with m-learning, virtual patients, and virtual reality than web-based learning.7
Like the majority of this study participants, the global tendency is to institutionalize digital learning by blending it with the traditional teaching-learning methods. In fact, in due course, the digital learning may substitute some of the traditional pedagogical approaches for health science education, including the didactic lecture (face-to-face and teacher-centered model) and patient-based learning, but may not fully fit for all practical/skill-based education, as hands on training is irreplaceable for the required skills acquisition, especially for health workers.
As learned from the revised national eHealth strategy, although currently the predominant modality of learning is the traditional face-to-face, digital learning has drawn the attention of the Government of Ethiopia as well as other stakeholders as one of the potentially effective methods to counter the gaps in both the quantity and quality of the health workforce. The cost-effectiveness of digital learning is what was emphasized by the study participants, which is in agreement with two studies findings in Ethiopia that compared the cost effectiveness of blended digital learning with face-to-face learning and found that the cost of digital learning was up to 50% less than the latter (the mean cost per trainee was $1,023 and $1,648 for the first study and $116.80 and $235 in the second study, respectively). 27,28 Other studies from Nigeria and United States of America reported similar results. 12,29
Recently, the COVID-19 pandemic has also further accelerated the momentum and demand for digital learning solutions in Ethiopia22,23,30 and globally.31 Further, as per the Ambient Insight Research report, Ethiopia showed a 20% growth in self-paced eLearning rates between the year 2016 and 2021, indicating the potential of the market demand for digital learning.32
On top of enacting guidelines, policies, and strategies that favor implementation of digital learning, the government and development partners have suggested digital learning as potentially effective methods to help address the challenges;7,33,34 the shortage of health workers is worsening as the population size of Ethiopia is annually increasing by about 3.3 million.35 Nevertheless, the digital learning being less interactive is a concern not to revert the currently recommended student-centered teaching method to teacher-centered approach. As a mitigating strategy, while the repository in the digital devices mimics text and reference books, the virtual two-way interactions with instructors may mimic delivering courses in classroom. Therefore, in addition to uploading the course content and assessment questions, organizing some online interactive sessions may fill the observed gap and learners’ inconvenience in the absence of classroom two-way communications.
In general, the data triangulation from different sources indicated the consistency and reliability of the gathered information. However, the study is not without limitations. Due to Covid-19 restriction, it was not possible to conduct focus group discussion. The study did not include other mid-level health professionals (like health officers, anesthetists, optometrists, radiographers, and laboratory technologists), who can benefit from similar undertaking.
