Abstract

Purpose

Interprofessional education (IPE) for undergraduate students in the healthcare disciplines facilitates the acquisition of skills required for interprofessional collaboration, which is critical for patient care. This study assesses the need for and perceptions of IPE and interprofessional collaboration among undergraduate students in nursing and medicine in South Korea.

Participants and Methods

This was a cross-sectional survey of undergraduate students in nursing (n = 130) and medicine (n = 68), who had never been exposed to IPE, using a convenience sampling method. The Readiness for Interprofessional Learning Scale (RIPLS) (19 items), Interdisciplinary Education Perception Scale (IEPS) (12 items), and Interprofessional Education and Collaborative (IPEC) Competency Self-Assessment Scale (16 items) were used. Data were analyzed using descriptive statistics, χ2 test, and independent sample t-test.

Results

Students in both schools almost equally indicated the need for IPE and practice-based IPE in their clinical rotations, focusing on patients in general wards, and wanted to learn teamwork. The mean RIPLS scores were 68.5 ± 5.62 in nursing students and 67.5 ± 6.53 in medical students, and those of the IEPS were 57.0 ± 7.03 in nursing students and 58.7 ± 7.08 in medical students, without significant differences. Nursing students scored significantly higher on the positive professional identity subscale of the RIPLS, whereas medical students scored higher on the competency and autonomy and perceived need for cooperation subscales of the IEPS. The total scale scores on the IPEC Competency Self-Assessment Scale were 65.2 ± 3.35 for nursing students and 67.4 ± 2.96 for medical students, the latter having a significantly higher score.

Conclusion

This study revealed differences in needs and perceptions regarding IPE and interprofessional collaboration between schools. These findings warrant further research to design IPE program goals and strategies that are reflective of students’ needs.

Introduction

The delivery of effective and high-quality patient care demands collaboration among healthcare professionals. Today, more than ever before, healthcare providers have realized that patients benefit more from interprofessional teams that mutually respect one another, communicate effectively, and coordinate patient care.Citation1 The literature suggests that high levels of interprofessional collaboration lead to better patient outcomes, improved patient satisfaction, and higher workplace satisfaction among healthcare professionals.Citation2,Citation3 Accordingly, healthcare professionals are increasingly required to cooperate and collaborate more closely in the delivery of care.Citation2

Interprofessional education (IPE), defined as two or more health or social care professionals learning knowledge and skills about, from, and with each other,Citation4 is critical in creating effective collaboration between them, resulting in better patient outcomes. The benefits of IPE for the healthcare system were also reported, including employment and workplace culture and collaborative practice.Citation5 After embedding IPE in curricula for students in nursing, medical, or allied healthcare profession, its effectiveness was described as follows: to provide a foundation to link to real-world experiences, enhance the confidence of individuals’ professional identity, and help students better understand the professional roles between disciplines.Citation6Citation9 Most recently, an experimental study on IPE with a control group reported that the participants in the experimental group had higher scores in interprofessional knowledge and competence compared to the control group after the IPE intervention.Citation10

Although learning through IPE can occur in either academic or clinical settings,Citation11 the World Health Organization (WHO) recommends implementing IPE as an integral part of the curriculum of undergraduate medical and health-related professions.Citation5 As the early interaction of students from different health disciplines facilitates the acquisition of the skills required to work effectively in a healthcare setting,Citation1,Citation12 IPE should start early, targeting undergraduate students.

The importance of IPE is gradually being recognized.Citation2,Citation13Citation15 In particular, the importance of close collaboration involving nurses and doctors equally and actively has been highlighted to ensure the quality of care and better outcomes in the delivery of healthcare.Citation3 However, thus far, studies on IPE in nursing and medical education in Korea have mostly been conducted on introducing the IPE conceptCitation16,Citation17 and faculty or student perceptions, thus revealing that both have fewer opportunities to experience a systematically designed formal IPE program. Hence, there is limited evidence on the levels and differences in student perceptions of IPECitation17,Citation18 and that of their IPE competency.

Prior to designing IPE programs to develop competencies that result in favorable outcomes, assessing and prioritizing educational needs and perceptions would be valuable for health care students,Citation18 particularly, for undergraduates.Citation19 Also, assessing the needs of healthcare professionals equally and recognizing their diversity helps establish an ethical and transparent learning environment for IPE,Citation20 which will ensure a beneficial program. Therefore, this study aimed to assess and compare IPE needs and perceptions among undergraduate students in nursing and medicine who are in an environment where IPE implementation has just begun. This study provides innovative and valuable information to verify the aspects that should be differentiated or assimilated in establishing early IPE program strategies for this population.

Materials and Methods

Setting and Participants

A cross-sectional study design was used with undergraduate students from the schools of nursing and medicine at two universities located in Gangwon Province in South Korea. The average number of students admitted every year in both the schools of nursing and medicine are 75 and 65, respectively. In these universities, the schools of nursing run four-year programs, and the schools of medicine run six-year programs since they have been established 30 years ago or more. These schools were selected based on the similarity of their curriculums: basic science courses and introductory courses related to the specialty in the second academic year, and major courses and a clinical practicum beginning in the third year until graduation. Neither school has officially incorporated IPE into its curriculum.

A convenience sampling method was used to recruit participants from each school. Students from the second through fourth academic years were selected because of the similarity in their levels of basic, introductory, and major courses taken and their availability at the time of data collection. Those who had previously experienced IPE were excluded.

The estimated sample size was calculated to be 170 with a significance level of α = 0.05, a statistical power of 80%, and an effect size (Cohen’s d) of 0.5, which is a medium effect size.Citation21 The participants were recruited through flyers, on-and offline bulletins in student communities, and in-person contact by research assistants among all students enrolled in their second and fourth academic year from both universities at the time of data collection which was from June to September 2020. The number of nursing and medical students who voluntarily responded were 143 and 70, respectively, of which 198 who completed the questionnaire were included in the final analysis (7% attrition rate).

Measurement Instruments

A structured questionnaire was used to collect information on the participants’ demographic characteristics including sex, age, the duration of study, specialty, and the need for IPE. Three validated self-administered scales were used to assess the students’ perceptions of IPE and interprofessional collaboration. The Readiness for Interprofessional Learning Scale (RIPLS),Citation22 Interdisciplinary Education Perception Scale (IEPS),Citation23 and Interprofessional Education Collaborative (IPEC) Competency Self-Assessment ScaleCitation24 were validated, published in English, and licensed for public use.Citation6 Specifically, the RIPLS was validated with Korean students in nursing, medicine, and other allied healthcare professions, such as physiotherapy, occupational therapy, and dental hygiene by Lee et al,Citation25 and it was also used to measure the effectiveness of IPE for medical and nursing students.Citation26

The other two instruments, the IEPS and IPEC Competency Self-Assessment Scale, were translated into Korean through a standard forward-backward translation procedure,Citation27 as follows: The first translation was performed independently from English to Korean by one nursing professor and two nurses who were bilingual. Then, the Korean translation was independently translated back into English by two other bilingual translators who majored in nursing. Four professors from nursing and medicine then compared the back-translated version to the original and decided that it was acceptable, with a few minor changes in wording. The content validity was verified using the Content Validity Index (CVI) and a panel of six expert judges, consisting of a nurse, three nursing professors experienced in instrument translation and implementation research, and two professors from the school of medicine who had experience with IPE for students and research. To determine the CVI, members of the panel were asked to rate each scale item in terms of its relevance to the underlying construct using a Likert-type 4-point scale. Those items that received a rating of either 3 or 4 by the experts were judged to be relevant, and the CVI of the translated Korean version of the IEPS and IPEC Competency Self-Assessment Scale were 0.96 and 0.94, respectively. The scale is considered to have excellent content validity at a CVI of 0.90 or higher,Citation28 thus the content validity of these scales was determined to be acceptable.

Readiness for Interprofessional Learning Scale (RIPLS)

The RIPLS consists of 19 items and was validated for eight health professions by Hu and Bentler.Citation29 It contains four subscales: teamwork and collaboration, negative professional identity, positive professional identity, and roles and responsibilities. The Likert scale ranges from “strongly disagree” (1 point) to “strongly agree” (5 points); the higher the score, the more positive the attitude toward interprofessional learning. In a previous study using the Korean version of the RIPLS,Citation25 for instrument reliability, Cronbach’s alpha was 0.880. In our study, Cronbach’s alpha for the total scale was 0.883, and those of subscales, ie teamwork and collaboration, negative professional identity, positive professional identity, and roles and responsibilities, were 0.858, 0.831, 0.814, and 0.752, respectively.

Interdisciplinary Education Perception Scale (IEPS)

The IEPS is a 12-item instrument that measures perceptions of interprofessional cooperation. The scale has three factors: competency and autonomy, perceived need for cooperation, and perception of actual cooperation.Citation30 Items responded to are measured using a Likert scale ranging from “strongly disagree” (1 point) to “strongly agree” (6 points). A higher score indicates a more positive perception of interprofessional cooperation. The reliability, validity, and normative data of the IEPS for several allied health professions have been published.Citation31 In this study, for the whole scale, the Cronbach’s α was 0.865, and the Cronbach’s α of the three subscales, competency and autonomy, perceived need for cooperation, and perception of actual cooperation, were 0.783, 0.742, and 0.870, respectively.

Interprofessional Education Collaborative (IPEC) Competency Self-Assessment Scale

To measure students’ perceptions of IPEC competency, a 16-item instrument consisting of two factors, interprofessional interaction and interprofessional values, was used. The interprofessional interaction subscale primarily comprises items from the teams and teamwork domain of the four IPEC domains originally defined by the IPEC expert panel,Citation32,Citation33 with one item each based on competencies from the interprofessional communication and values/ethics domains from the four IPEC domains. The interprofessional values subscale comprises items only from the values/ethics domain. Items are measured using a Likert scale ranging from “strongly disagree” (1 point) to “strongly agree” (5 points). A higher score indicates a better perception of competencies for interprofessional collaboration. In this study, for the whole scale, the Cronbach’s α was 0.924, and the Cronbach’s α of the two subscales, interprofessional interaction and interprofessional values, were 0.874 and 0.856, respectively.

Data Collection

Informed consent was obtained from each student prior to participating in the study. Data collection was conducted by two research assistants, each of whom had completed an 8-hour training session encompassing the ethical considerations and study objectives, from the survey context to a detailed explanation of the questionnaire and data collection procedure. Next, the research assistants administered it among themselves, and overviewed other aspects of the survey and research assistant role to ensure consistency. Using a set of standardized instructions, the research assistants explained to the participants the purpose of the study, the content of the questionnaire, and the fact that their participation was voluntary and would not affect their grades. Subsequently, the questionnaire was distributed to the students according to their schedules. During the survey, the participants were told to ask questions or for help whenever they needed, and no specific difficulties were reported. It took approximately 20 minutes to complete the questionnaire.

Data Analysis

Descriptive statistics were calculated for the demographic variables. The variables of interest were compared between the schools using the χ2 test and independent sample t-test. The significance level for two-tailed tests was set at 0.05. All analyses were performed using IBM SPSS Statistics, version 25 (IBM Corp., Armonk, NY, USA).

Ethical Considerations

The study protocol was approved by the Institutional Review Board of Wonju College of Medicine, Yonsei University (CR319091). Students who met the inclusion criteria were invited to participate in the study. Those who agreed to participate provided written informed consent after receiving an explanation of the purpose of the study, including assurance of privacy, potential benefits and risks, the voluntary nature of their participation, and the provision to withdraw without consequence.

Results

Participant Characteristics

As shown in , more than 70% of the participants were women and nursing students with a mean age of 21.7 ± 1.84 years old. With regard to year in school, 24.7% were sophomores, 35.9% were juniors, and 39.4% were seniors.

Table 1 General Characteristics of the Participants (N = 198)

Comparison of IPE Needs Between Nursing and Medical Students

Almost all nursing (90.6%) and medical students (89.7%) indicated a need for IPE, without any significant difference between the schools. In addition, most students in both schools (nursing = 81.5%; medical = 88.2%) believed that IPE should be applied in the curriculum in the third and fourth years, and there was no significant difference. However, there were some significant differences regarding IPE contents, essential skills to be learned through IPE, and learning methods for IPE, as shown in .

Table 2 Comparison of Interprofessional Education (IPE) Needs Between Schools (N = 198)

Regarding IPE contents, both nursing and medical students almost equally listed ward patient care and community chronic patient care, whereas nursing students wanted to learn critical patient care in general wards more than medical students (χ2 = 20.142, p = 0.000). Regarding the essential skills to be learned by IPE, which was investigated by an open-ended question, more than half of nursing students (66.1%) claimed that IPE was necessary to learn collaboration and teamwork, whereas medical students assessed collaboration and teamwork, and mutual understanding for other professionals in a similar proportion (χ2 = 21.967, p = 0.000).

In terms of IPE learning methods, nursing students preferred simulation (χ2 = 25.209, p = 0.000) and role-playing (χ2 = 6.681, p = 0.008) compared to medical students. However, half of the students in both schools wanted IPE during clinical rotation with no significant difference between the two schools.

Comparison of Variables Between Nursing and Medical Students

RIPLS

The mean scores for the RIPLS were 68.5 ± 5.62 for nursing students and 67.5 ± 6.53 for medical students, with no significant difference between schools. The mean score for each RIPLS domain, and a comparison between nursing and medical students, are presented in . Nursing students gave significantly higher scores on the positive professional identity subscale than medical students (t = 2.469, p = 0.014).

Table 3 Comparison of the Variables Between Schools (N = 198)

IEPS

The mean scores for the IEPS total scale were 57.0 ± 7.03 for nursing students and 58.7 ± 7.08 for medical students, with no significant difference between schools. However, there were significant differences between the two groups in the domains of competency and autonomy (t = -3.910, p = 0.000), and perceived need for cooperation (t = -2.354, p = 0.019), with medical students having higher scores in both domains (see ).

IPEC Competency Self-Assessment Scale

The total scale scores on the IPEC Competency Self-Assessment Scale were 65.2 ± 3.35 for nursing students and 67.4 ± 2.96 for medical students, with medical students having a significantly higher score (t = −2.108, p = 0.036). As reveals, medical students also scored significantly higher on the interprofessional interaction subscale (t = −2.267, p = 0.024).

Discussion

This study explores and compares the overall need for and perceptions of IPE among undergraduate nursing and medical students with no previous experience of IPE. We employed prominent internationally-applied instruments to assess the participants’ perceptions. The study findings provide insight into IPE and suggest how healthcare educators should design them based on the needs and perceptions of nursing and medical students, who as future healthcare professionals, will be required to effectively collaborate as a healthcare team.

The results indicate that most students from both schools recognized the need for IPE to mutually understand other professionals and learn teamwork. This is in line with the findings of previous studies that suggest the need for IPE for collaborative teamwork and to cultivate roles and responsibilities to undergraduate students in medicine, nursing, pharmacy,Citation34 and other allied healthcare programs (eg, clinical laboratory science and physiotherapy).Citation6,Citation34 Regarding the timing for starting IPE, most students indicated the fourth academic year; however, no existing evidence indicates the right time for health professionals to begin IPE. Berger-Estilita et alCitation35 reported that a third of medical students indicated that IPE should start just before or during clinical training, while another third indicated that IPE should start as early as the first year of undergraduate education and training. Some studies have also suggested that IPE should be planned from the beginning of the undergraduate program.Citation36Citation38 Given the inconsistent evidence on the ideal timing for IPE, further research is warranted to explore when to start IPE in terms of reflecting student needs and perspectives and ensuring the effectiveness of the training.

Regarding IPE contents, most participants indicated “ward patient care” and “critical patient care in general wards”, whereas “community chronic patient care” was included by less than 15% of students. The participants in this study seemed to focus more on patient care in the hospital, which may be related to the scope of their clinical placements during academic training. In professional healthcare education for undergraduate students in South Korea, most of the training takes place in inpatient wards and emphasizes the improvement of technical skills.Citation39Citation41 In particular, the critical care of hospitalized patients requires the cooperation and collaboration of skilled professionals from multiple disciplines.Citation42 Therefore, IPE related to critical inpatient care should be reflected in the education and training of nursing and medical students.

Regarding learning methods, nursing students preferred simulation and role-playing, whereas medical students preferred a workshop. These differences should be noted, as most IPE programs for nursing, medicine, and other healthcare professions in previous studies included simulation along with lectures,Citation43 regardless of the participants’ characteristics and needs. Although simulation is a teaching method that provides immersive experiential learning and allows for disciplines to work together in a safe environment,Citation44 the effectiveness of simulation-enhanced IPE and related factors has been questioned and is an area need of further investigation.Citation43 In addition, gaps in student learning methods between professions should be taken into account to ensure the impact of IPE on participants’ outcomes.Citation18 Nevertheless, students in both schools wanted IPE during their clinical rotation. This finding is in line with the suggestion that basic and clinical science be integrated into the IPE curriculum to contextualize theoretical learning in clinical practice,Citation37 and that implementing practice-based IPE in students’ placement curricula would boost collaboration among healthcare providers.Citation45 Therefore, an IPE program for nursing and medical students should be constructed in the clinical setting, during clinical placement, which can integrate theoretical learning into clinical practice.

Nursing students were more positive in their professional identity than medical students based on their RIPLS subscale scores. A well-developed professional identity is important to engage in teamwork.Citation35 However, stronger definitions of individual professional roles and the uniprofessional socialization of healthcare providers may be significant barriers for interprofessional collaboration, causing healthcare professionals to work independently in meeting their own client care goals.Citation46 Therefore, it is important for students to develop dual identities as members of the medical team and in their professional society for interprofessional practice.Citation46

Contrary to a higher professional identity score, nursing students showed a lower competency and autonomy score on the IEPS, which measures attitudes toward interprofessional collaboration. Furthermore, nursing student scores on the “perceived need for cooperation” on the IEPS and “interprofessional interaction” on the IPEC Competency Self-Assessment Scale were also lower than those of medical students. Yune et al’sCitation18 study reported similar results, indicating that medical students perceived their collaborative leadership competency to be higher than that of students in other majors, such as nursing and pharmacy. This results should be interpreted in consideration of the literature suggesting that the constructs underlying these subscales may be affected by experience and training.Citation24 Student responses to the items may have been affected by individual experiences related to interprofessional collaboration in clinical placement or taking other courses that were not measured in this study.

Another related aspect to consider is the impact of gender stereotypes and power relations on self-evaluation of competency, autonomy, and the need for cooperation. Students are likely to evaluate themselves and their needs within the context of stereotypical structures of gender and power, in which men predominate the field of medicine and have more power, and women predominate the field of nursing and have less power. Given that gender stereotypes and power relations tend to be barriers to interprofessional collaboration among students from different professions,Citation47 educational strategies to promote mutual understanding among the professions should be developed and introduced earlier in IPE courses for nursing and medical students, before students’ professional biases are established.Citation37

To our knowledge, this study is the first to provide valuable information on IPE among nursing and medical students in South Korea. However, the generalizability of the results may be limited because of the possibility of selection bias related to the sample from only two universities in one province of South Korea. Future research should include a larger sample size and more schools. Moreover, this study was conducted during the COVID-19 pandemic, which raises the following considerations. First, in this period, healthcare professionals, especially nurses, were presented in the media as very important figures, more than ever before in South Korea.Citation48 Thus, nursing students were likely to have an increased awareness of the importance and responsibility of their profession, which may have influenced the students responses to professional identity scores in this study. Previous researchCitation49 reporting an increase in professional identity scores among nursing students later in the first wave of COVID-19 (compared with the earlier phase of the COVID-19 pandemic) may be in line with this explanation. Second, during the COVID-19 pandemic, the clinical rotations of students in the healthcare profession were forced to be limited to reduce transmission and protect students from infection. This limited clinical experience may have impacted the students’ considerable learning needs in clinical practicum. Although these interpretations should be limited to this study, the COVID-19 crisis is a milestone in the development of IPE for healthcare professionals, as the need for interprofessional collaborative practice is emphasized more than ever by healthcare educators and students.Citation50,Citation51

Conclusions

This study found that students in nursing and medical schools agreed on the importance of implementing IPE in their programs. However, there were differences between nursing and medical students regarding the contents, essential skills to learn, and learning methods for IPE. Therefore, including IPE in the curriculum for this population should be according to their respective needs, as much as possible. In addition, differences between nursing and medical students in their readiness and perception of interprofessional relationships and competencies suggest that an early assessment of these issues is warranted. Thus, strategies that reflect these differences should be incorporated into IPE programs to establish effective IPE. Further studies are essential to evaluate the effectiveness of IPE tailored to the needs of students in diverse healthcare disciplines.
