This study aimed to assess the acceptability of VP cases as a CPD approach among nurses at health centers in Rwanda. The study assessed acceptability by examining the following variables: perceived ease of using the VP system, perceived usefulness of VP cases, training relevancy of VP cases, results demonstrability of using VP cases, perceived external control of VP cases, and behavior intention of accepting VP cases as a CPD approach. Generally, nurses who work at health centers and who participated in this study expressed agreement or strong agreement that VP cases can serve as an effective CPD approach.
In the technology acceptance model [9] that informed this study, they suggest that perceived ease of use and perceived usefulness are two major determinant variables that predict behavior intention of accepting a technology [9]. While perceived usefulness and perceived ease of use are key predictors of behavior intention, the technology acceptance model posits that the variables of job relevancy (referred to as training relevancy), results demonstrability, and perceived external control predict the perceived usefulness. Participants in this study agreed or strongly agreed with the statements related to these predictors and their responses showed a significant correlation with perceived usefulness. Furthermore, participants expressed consensus that the VP system applied was easy to use. Collectively, these responses paint a comprehensive picture, indicating that nurses at health centers who took part in the study have the behavioral intention of using VPs as a CPD approach. Individuals intend to perform those actions with the highest product of expectancy for achieving the aspired goal [17].
Moreover, the findings in this study agree with previous studies conducted on the use of VP cases in pre-service education which have demonstrated acceptability by the students [18–20]. Nevertheless, to the best of researchers' knowledge, this is the first study examining the behavioral intention of adopting VPs as a CPD approach among practicing nurses. According to many previous studies, the utilization of VP cases is founded on the assumption that it facilitates the exposure of students to clinical scenarios thereby enhancing their clinical reasoning abilities [21–23]. Based on this assumption, a practicing nurse has opportunities to interact with actual patients and may not necessarily require VP cases for learning. On one side, this argument holds validity, especially for a nurse or any healthcare provider working in an environment that includes both senior and junior professionals. If a such setting fosters a learning culture where senior healthcare providers actively engage in discussion with their junior counterparts regarding clinical cases, the significance of VP cases would be diminished.
However, on the other side, nurses or healthcare providers who lack the opportunity to engage in regular case discussions with their senior colleagues (as in this study setting), our results indicate that VP cases can serve as an approach to bridge this gap. VP cases can not only feature scenarios that reflect contemporary clinical reality but also offer the opportunity for self-assessment regarding case management using feedback from experts. This is a crucial factor that can consistently enhance the quality of health service delivery, as junior healthcare professionals receive ongoing mentorship from their seniors (experts). Probably, this could explain why the nurses at health centers in this study agreed or strongly agreed that VP cases can improve their performance. In health centers in Rwanda, and likely in many Sub-Saharan African countries and other low-resource settings, nurses typically work alone in consultation rooms and make decisions that often physicians do in settings with better access to physicians and hospitals. They attend to patients with various diseases and are tasked with deciding on case management or making referrals to district hospitals. Most often, neither managing the case at the health center nor transferring it to the hospital provides an opportunity to receive feedback. In health centers, patients are ambulatory, and there are no mechanisms in place for nurses to assess the impact of their decisions. Similarly, when nurses transfer patients, they never receive feedback about the correctness of the motives behind their decision to transfer. In this context, learning through VP cases can offer opportunities for receiving feedback from experts, thus promoting confidence in case management. As we see it, better training in the form of VP-based CPD can help to preserve scarce resources like access to physicians and time to treatment as well as prevent incidents where a patient that really should be referred to a hospital, is not transferred due to lack of experience and/or clinical reasoning skills among less experienced nurses in low-income regions.
However, the adaptation of VP cases as a CPD approach within health centers necessitates careful consideration of institutional support. “Generally speaking, people intend to perform a behavior when they evaluate it positively and when they believe important others think they should perform it”[17p.12]. In the Technology Acceptance Model, external control is defined as the degree to which an individual believes that the organization can provide the necessary support. Previous studies on electronic devices and internet connectivity have produced varied findings: certain health centers in Rwanda are equipped with computers and have fast and stable internet connections, whereas others lack sufficient electronic devices, and face challenges with both the speed and stability of their internet [24, 25]. In this study, participants were provided with tablets and internet access, and we did not evaluate the capability of existing electronic devices and the internet infrastructure to support VP cases as a CPD approach. Nevertheless, the participants’ responses to perceived external control were positive. While some participants expressed disagreement with certain statements of this construct, the majority either agreed or strongly agreed that their institutions are capable of offering the necessary support. The positive expectation regarding the institutions’ support may stem from participants' belief in the adequacy of existing infrastructure to facilitate the use of VP cases. Additionally, the commitment by the Rwandan government to equip all health institutions, including health centers, with fast and stable internet by the year 2024 could have influenced participants’ confidence in asserting that their institutions can offer the required support.
