The present study conducted to find out the difficulties that may impede IPE application in Sudan. Participation of the study necessitate that subjects are familiar with the concept of IPE. Therefore, selection of the study area and research subjects has been based on the factor that participants being exposed to the model through the program of master of health professions education in Sudan Medical Specialization Board, where various disciplines learn from, with and about each other. This conforms with the definition of IPE, which is focused on the three main elements of the interaction, when students from two or more professions learn about, from, and with each other to enable effective collaboration and improve health outcomes in the future (10)
Although response rate of the study was 51.53% and number of participant is 101 but in medical literature scientist accept studies with small sample especially if they test presence of effect rather than the effect size. Political instability and network interruptions in Sudan attributed partially to reduced response rate. Efforts exerted to encourage participation in spite of the fact that the duration of data collection extended.
Implementation of the model is a bit complex process that requires inputs from multiple factors operating simultaneously. Issues related to the satisfactory application of IPE grouped into factors pertinent to the institute, learners and teachers. Those related to institute can further categorized into aspects related to the curriculum, top management enthusiasm, commitment, allocation of funds and availing suitable premises. The curriculum components are content, structure, timeline, strategies and implementation.
The IPE necessarily links various specialties in a common course where all of them must learn. In IPE, meticulous planning of calendars, learning approaches and coordinated sequence of courses are very important factors prior to execution. The courses need meticulous planning and design before the start of the academic year. The phases and venues are coordinated to suit students from all disciplines. In our study, many of the participants thought that introducing the model into existing curricula –especially if traditional- might need adjustment. There is significant difference in the responses among participants from different specialties (P 0.01) and this could be due to condensed curricula of certain schools compared to others. Time allocated for them, as reported by 60.4% of the participants, need modification. On correlating this response in relation to different variables, various colleges and academic rank showed highly significant association (P value 0.013, 0.001 respectively). Likewise, the diverse curricula of various specialties and their emphasis may be behind this response.
In our study, the majority of the participants (96%) believe that learning approach and styles need modification. Correlating approach and styles to academic rank found to be significant (P value 0.001). This in agreement with certain studies which pointed out that in most of IPE setting simulation-based instruction, e-learning and problem solving are the commonly used as effective methods (15). This result also consistent with the study conducted by Rosenfield and his colleagues in 2011, in which the participants were dissatisfied with delivering IPE in large group lecture that detracts from the interaction of groups and distorts the image of IPE/(18)
In the present study, 98% of the participants believed that the coordination and support of the administrators and top management of the institute are essential to apply 𝐈𝐏𝐄 smoothly, while the rest (2.0%) were neutral. Academic rank found to be significant factor (P value 0.005). This finding resembles the conclusion stated by other workers, that commitment of the program directors and top management and their enthusiasm to model are crucial for the success of application. (10) The support of the leaders is crucial, as IPE especially in the early stages of implementation needs financial support, adjustment and modification of the plans, academic calendars and policies, training for the staff and learners as well as authority.
Participants express their opinion with regard to the institute, they enforced that committed, and dedicated leadership is crucial because modification of the institute policies and adjustment of the strategic plan are necessary to allow induction of the model. They assumed that presence of many health schools in one institute is considered an advantage to facilitate the application, and presence of health schools within geographic vicinity is considered by some author as factor that ensure easy and smooth application(16). This contention is understandable in a country like Sudan where transport represents an obstacle. However, Buring (17) and his co-worker pointed out that the model should be implemented even if in isolated school. They suggested collaboration with other institutions or community service facilities. For the didactic component, online education might be an attractive solution.
In our study, some of the participants believed that collaboration across different institutes might not succeed due to the differences in socioeconomic status and physical distances. The participants emphasized the role of the institute in organizing and preparing the environment and availing the funds and resources needed to recruit and train extra staff.
For IPE the teachers or facilitators represent a fundamental element for application (17). Implementation of the model is a new experience for educators, even the experts. This is because IPE involves work as a member of a team from different disciplines, as well as facilitation in groups of different background (17). Therefore, training of the teachers to familiarize them with the model seem crucial step for success of implementation. In our study majority of the participants, believe that teachers involved need training prior to implementation. Sufficient number of trained staff members is considered mandatory in agreement with other study (16).
In the process of IPE, various professions brought to work together. Unfortunately some of them might fetch their professions’ ego with them and this represents a major obstacle for the smooth application of IPE (18, 19). Because it negatively affects both sides, the arrogant and the other who may either play a defensive and aggressive mode to support their professional identity or withdraw and retract leave their space empty and this will subsequently put the success of experience at risk. An essential factor for the success of the model includes motivation and enthusiasm of the staff. This idea is consistent with the findings of the current study where most of them agreed that this factor is essential for the application. Other obstacles that mentioned by the staff include political and economic instability of the country lead to phenomenon of so-called “brain drain” that resulted in lack or inadequate staff. They considered that objectives, roles and responsibilities, duties and values should be clear, shared and agreed upon to reduce conflict and alleviate friction among team members(16).
The third pillar of IPE is the learner. The factors related to this aspect play a major role in application of the model. In our study majority of the participants (approximately 71%) believed that candidates with different levels of knowledge might face different obstacles to application of 𝐈𝐏𝐄. Other candidates assumed that it is essential to match the levels between different students, i.e. the academic level (clinical, preclinical and basic sciences….etc.) to alleviate this obstacle and avoid attitude difficulties. This is actually resolvable if the IPE model carefully planned at the optimum part of the curriculum where participants are in the same level i.e. that is to say in basic, preclinical or clinical phase. Other studies found that selection of the joint professions should be based on mutual collaboration of the specific course e.g. medicine, nursing, dentistry, nutrition etc(16) Moreover, the model should be designed and prepared precisely with clear objectives and strict responsibilities, duties and solid restricted values(20). Students and their attitude to the model considered essential factors and this is rational since transformation or innovation take place successfully if the stakeholders are motivated and willing to join.
Large number of the students is considered by majority of workers and even learners to be a risk factor for the model (15). The reason is that implementation of the model may be easier if the number of learners is small to facilitate control and distribution of the duties and responsibilities. Small number of learners enables instructors to draw their enthusiasm and motivation to the model. In the current study, most of the participants assumed that learners with previous experience affect application. This may be a double-edged sword. The learners who have good experience will be motivated and willing to be part of the model and will have the concept of teamwork. While those learners who exposed to bad experience will be a focus of negative consideration and will be reluctant to partake in the application of the model. Some of the participants believe that motivation and communication skills of the learners are essential factors in facilitating the implementation. In an study conducted in Canada, learners underwent brief exposure to IPE and indicated that small group activities promote dynamicity among group and is preferable over lectures (15).
In the present study, participants had chance to share their thoughts and opinions. Some of the participants believe that students have to learn and practice problem solving first to be ready for IPE application. Others claimed that learners-as the case for staff- need training for IPE. Other participants argued that academic levels of student might affect the application. In other words, students in early years may differ from those in the advanced year (junior vs. senior/ clinical vs preclinical). Some stated that IPE must be introduced at an early level. In authors opinion meticulous planning of the model and selection of the most appropriate part or theme of the curriculum to implement it can address all these concerns.
IPE can be implemented in different setting and different phases of the curriculum such as lecture (least preferable)(15), simulation based laboratories and clinical setting.
Participants emphasized the crucial role of clear objectives and strict action plan for the success of the model. As teams with many members of different background can easily miss the direction with subsequent failure of the model (21). Therefore, some of the participants suggested that IPE model need to be introduced in training and work place as well, so those who have no idea will know its benefits to patients(22). IPE although suggested as an essential concept of medical education but it is a complex procedure, the success of it rely in different factors
Recommendations
Further studies needed to determine the awareness of medical and health school about the concept of IPE and to determine the perception and attitude of other stakeholders such as ministries of health, higher education, health related partners and organizations. More studies to address other obstacles and difficulties that face IPE and explore ways to overcome them.
