Teamwork has always been essential in clinical environments; therefore, interprofessional education (IPE) has become an important factor of medical education in recent years. This is also because medical practice has become more complex and specialized than ever before; disease patterns have changed from, for example, a simple communicable disease to complex multi-morbidity chronic diseases. Moreover, the working hours of medical staff are limited to ensure a safe medical environment. The World Health Organization (WHO) has proclaimed the importance of IPE since 1988 for these exact reasons [1].
All healthcare professionals have their own expertise and skills and communicate and collaborate among themselves continuously, with the common goal of patient care. This is the main reason that teamwork is important in healthcare. Furthermore, no medical practice can be performed by one healthcare professional alone. During their treatment, a single patient meets doctors, nurses, medical technologists, and even administrators in different sections of the healthcare system. The more specialized a healthcare system is, the more steps a patient experience.
When healthcare-associated students become practitioners, they become acculturated into their own professional identity, which could lead to barriers in collaboration in a clinical environment [2]. Therefore, teamwork and interprofessionalism should be taught to healthcare students as part of their undergraduate education.
Most undergraduate IPE classes are aimed at medical students (MS) and nursing students (NS), and there are many different types of classes and lessons. The effects of IPE on MSs and NSs are well-known, and to date, similar results have been achieved, regardless of the method used. IPE contributes to students identifying their own shortcomings and recognizing the value of their colleague’s approach and to diminishing stereotypes and hierarchies. An existing study showed that in the service-learning setting of a student-run free clinic, interprofessional (IP) group students showed improvements in IP perception and clinical reasoning skills [3]. In a German study, medical and nursing students took part in problem-based learning and were able to expand their knowledge of the roles of the other profession; further, the IPE course had a positive effect on students’ mutual appreciation [4]. In simulation-based training, IP students gained enhanced understanding other professionals’ work, communication, teamwork and leadership, and self-efficacy as better team leaders [5–7]. IPE has also been shown to enhance the development of interprofessional thinking and patient-centered care, acquiring shared knowledge, and promoting mutual understanding [8–10].
There are several difficulties to consider when aiming for successful IPE, the most prominent being coordinating and harmonizing the curricula of the two professions [11]. Recent studies compared an IP group and a uniprofessional (UP) group, in the belief that evidence of IPE’s effectiveness was still lacking. In Račić‘s study, the IP group consisted of medical, dental, and nursing students and three UP groups consisted of their profession students. All groups showed higher follow-up scores on diabetes knowledge than baseline scores; however, the IP group’s posttest score was higher than those of the UP groups. Additionally, the IP group had a more positive self-assessment of communication and teamwork skills [12]. In a Taiwanese study, the IP group (medical and nursing students) gained higher interprofessional communication and collaboration than the UP (MS) group in problem-based learning on clinical ethics [13]. Berger et al. [14] used an IP seminar to compare an IP group of undergraduate medical and other healthcare students and a UP group (undergraduate MSs) in German medical education. The IP group showed a more positive reaction and higher mean scores on self-reported knowledge gains in the area of group dynamics. However, scores for communication and teamwork and IP learning increased in both groups. The UP group showed improvement in medical knowledge but only some improvement in communication and teamwork skills.
IPE requires active learner participation, interaction, and active exchanges between learners from different health professions to improve IP collaboration [15]. Although students from more than one healthcare profession must interact and learn together for education to be defined as IPE, interaction in a single profession group seems effective to some extent. IPE sometimes involves a single profession, because of the difficulties in adjusting the curriculum.
This study aims to examine the effects of IPE on self-efficacy and attitude by comparing the UP group of MSs and the IP group of medical and nursing students. Additionally, we conducted sub-analyses on MSs vs NSs in the IP group and on the IP group MSs vs UP the group MSs. The concept of IPE is still underdeveloped in the context of undergraduate medical education in Korea, which is why we examined the effectiveness of IPE in Korean undergraduate medical education.
