Effectiveness of clinical scenario dramas to teach doctor-patient relationship and communication skills

Background The doctor-patient relationship in China has deteriorated in recent years, and poor doctor-patient communication is one of the main reasons. How to effectively carry out doctor-patient communication training originated from the West among Chinese medical students still to be studied. In the past decade, Peking Union Medical College has adopted clinical scenario drama to teach doctor-patient relationship and clinical communication skills. The aim of this study was to introduce clinical scenario dramas and evaluate its effectiveness in promoting doctor-patient relationships and clinical communication skills through students’ self-perceptions in Chinese medical students. Methods This study was a retrospective, self-controlled study and conducted from March 2009 to October 2018. Doctor-patient relationship and communication skills training were administered to all sixth-year medical students, which involved lectures and various clinical scenario dramas. The program totaled 24 h, of which each class session was 3 h, with 8 sessions in total. All students were requested to complete an anonymous 5 likert self-rating survey including self-confidence in using communication skills and self-perceived learning attitude and ability before and at the end of the course. In addition, they were requested to evaluate the curriculum after completion of the course. Results Clinical scenario dramas helped students improve their self-confidence in clinical communication skills except for psychosomatic history taking (p < 0.05). The interests for participation in clinical scenario dramas were higher compared to attending lectures (4.39 ± 0.610 Vs 4.07 ± 0.831, p<0.01). Study participants were highly satisfied in the course setting, teaching instructors and content (4.61 ± 0.546, 4.65 ± 0.535, 4.63 ± 0.534). The self-evaluation results demonstrated that clinical scenario dramas improved the learning ability of medical students (p < 0.05). Conclusion The use of clinical scenario dramas was helpful in teaching doctor-patient communication skills.

Background
In recent years, doctor-patient relations in China are deteriorating [1][2][3][4]. Doctors in China often face threats of violence and patients distrust the current health care system. According to a 2014 study of community hospitals in Heilongjiang Province, that 42.2% of medical personnel experienced violent attacks in the past year [5]. And researches indicate that doctor-patient disputes in China are largely due to poor doctor-patient communication [6,7]. Both medical staff [8] and patients [6,9] feel that there are serious problems in doctor-patient communication.
Previous studies from the West have shown that doctor-patient communication is influenced by many factors, including physician and patient communication style, patients' demographic characteristic, and demographic concordance between physician and patient [10][11][12][13]. But what are the barriers to good communication between Chinese doctors and their patients? In ancient China, the position of doctors was theocratic and patriarchal [14], so there was absolute dominance between doctors and patients. However, with the economic development in recent years, Chinese patients have a stronger sense of autonomy and rights protection. Similarly, previous studies in other Asian countries have found that under the collectivist view, patients are conceptualized as subordinates of doctors, who are more authoritative and dominate the discourse in medical consultations [15][16][17].
As we all know, good doctor-patient communication has the potential to help ease patient's emotions, facilitate patient's comprehension of medical information and improve in identifying the patients' needs, perceptions, and expectations [18][19][20][21]. But doctor-patient communication skills are not innate. Traditionally, Chinese doctors' communication ability can only be achieved through self-exploration in clinical practice. In the past decade, doctor-patient communication training courses [22,23] have been introduced to China from western countries. However, due to the differences between Eastern and Western cultures, whether these courses can be well accepted by Chinese medical students remains an open question. In addition, compared with the West, the Chinese people have a different understanding of education. In 《Origin of Chinese Characters (Shuo wen jie zi)》, Education (Jiao Yu) is defined as: Teaching (Jiao) is that students are to behave by following dictations from teachers; fostering (Yu) aims at leading children to be a man of virtues. Previous studies have shown that in China, doctor-patient communication training programs are limited in both medical school and graduate education, and they emphasize more on theoretical knowledge than practical training of communication skills [24]. Communication training not only need technical training, but more importantly helps students to explore the inner experience of people in different roles.
Based on the above reasons, beginning in 2007, the department of psychological medicine at the Peking Union Medical College Hospital (PUMCH) began teaching courses in doctor-patient communication and using clinical scenario dramas as a teaching method. Clinical scenario drama is rooted in roles theory, and it explores the experiential process of conflict and transformation of doctor-patient relationship with the help of dramatic technology. Its advantage is that it can help medical students who have insufficient experience of doctor-patient relationship to better understand the inner experience of different roles in doctor-patient relationship [25]. This study aimed to introduce clinical scenario drama and to evaluate the acceptability and usefulness of the program through medical students' self-perceptions.

Methods
The study protocol was approved by the Ethics Committees of the Peking Union Medical College Hospital, Beijing.

Study design
The study was a pre-post intervention study and conducted from March 2009 to October 2018.

Inclusion and exclusion criteria
Inclusion criteria were as follows: all sixth-year medical students from Peking Union Medical College (equivalent to third-year medical students in American medical colleges) participated in the medical clinical communication skills course.
Exclusion criteria: students who did not attend classes due to illness, international exchange programs, etc.

Course setting
The clinical communication skills course was a compulsory course in PUMC. The proposal to conduct the course was reviewed and accepted by the education committee of PUMCH. The clinical communication skills course included a total of 24 h of teaching, of which each class session was 3 h, with a total of 8 sessions. According to Calgary-Cambridge Guide and the actual situation of clinical practice in China [26][27][28], seven topics were covered in the curriculum, i.e., relationship building and empathy, obtaining patient psychosomatic history, explaining medical problems, negotiating treatment options, communicating bad news, coping with demanding patients, and communicating with relatives. Teaching consisted of 30-min of lecture and 2.5-h of clinical scenario drama for each session. Fifty to one hundred students for each grade were enrolled in the course and were divided into 2-4 groups.

Teaching instructors
Every group was instructed by two trained doctors who were experienced in conducting clinical scenario drama courses, small-group teaching methods and communication techniques. One of the teachers was a psychosomatic medical doctor who was very experienced in handling difficult conversations with patients and families and had over 10 years of experience. The other teacher was an internal medicine doctor from the PUMC department that specialized in gastrointestinal, general practice, oncology, geriatric or palliative medicine. All instructors had participated in an advanced communication training program that was funded by the Chinese Medical Doctor Association (CMDA). The program was a two 5-day retreat that focused on instructing clinical doctors how to teach communication skills to physicians-in-training.

Clinical scenario dramas
Below we describe the elements of a typical clinical scenario drama.

Script
There were three standardized scripts for each topic (Table 1), with two scripts being used during a 2.5-h clinical scenario drama. The content emphasized on doctor-patient communication in clinical practice. The scripts entailed realistic situations faced by doctors and their patients. Students were required to use the communication skills learned from the course to resolve difficulties and miscommunications typically faced by doctors and patients.

Rehearsal
Group members volunteered or were invited to play characters in the scenarios. Volunteers were helped by instructors to understand their roles with respect to the illness studied; the background of the patient's character, including age, gender, occupation, and demeanor; as well as the details regarding the patient's illness and enact their condition (Table 2). Volunteers had to place themselves in the shoes of the patient to understand the communication challenges they would experience as they describe their medical situation, emotional state, and key relationships. Non-character group members had to observe the rehearsal and design the stage background, light and acoustics, and so on.

Clinical scenario dramas
The stage directions for clinical scenario dramas were quite flexible. For example, the scene could be performed on a riser in front of an audience or in a circle surrounded by an audience. Depending on the scenario, the houselights were slightly dimmed or the room immersed in total darkness with spotlights to illuminate the stage. Furthermore, music could be used in the background, chairs and other props could be used, and group members could create imaginary settings, e.g., a hospital room, clinic, or office for the scenario. If needed, a brief introductory statement that sets the scene could be provided; for example, "In this scene, we will meet Mr. Lee, a middle-aged male patient who is angry because his doctor canceled his appointment without informing him". During the scenario, the characters', i.e., doctor and the patient, their personalities, inner conflicts and dilemmas between them were portrayed as closely to clinical reality, medical systems, laws and regulations. During this enactment, students tried to empathize with the feelings of the patient and understand the thoughts and behaviors. The "doctor" tried to solve the present difficulties by using clinical communication skills learned from the course.

Feedback and comments
After the enactment, the facilitator asked the actors to step out of their roles and share what they learned from the scenario. This was followed by a period of feedback and discussion whereby the facilitator asked the "doctor" to describe the skills he or she used to resolve the conflict. The observers were also asked to provide feedback. Finally, the "patient" was asked to discuss how he or she felt and to comment on the effectiveness of the "doctor's" communication skills. The feedback and group discussion sessions were focused particularly on the aspects of communication and lasted approximately 30 min. Afterwards the facilitator summarized the content or focused on issues not identified by the audience to provoke further thought and discussions.

Assessments
In 2003, the Chinese Medical Doctors Association, in conjunction with relevant professional organizations and drawing on international standards, organized and developed the first standardized training framework and evaluation questionnaire for "Practicing Skills of Chinese physicians in humanistic Medicine" suitable for domestic physicians [27,28]. On this basis, we incorporated clinical scenario drama as its teaching method, and made appropriate modifications to the curriculum framework and evaluation issues in the actual teaching process, gradually forming the existing self-rating questionnaire. The self-rating questionnaire used a 5-point Likert scale (1 = strongly disagree, 2 = disagree, 3 = neither agree nor disagree, 4 = agree, 5 = strongly agree) that was designed based on the aims of the course and included 7 items on self-confidence regarding communication skills and professional practice (before and at the end of the course), 8 items regarding self-perceived learning attitude and ability (before and at the end of the course). and 5 items rated on self-perceived satisfied and utility of the course (at the end of the course).

Statistical analysis
Statistical analyses were performed using IBM SPSS 20.0 and self-contrast methodology. The means and standard deviations were used to describe the total scores and single scores for each item on the self-rating questionnaire. Pre-and post-course scores were compared using paired t test. p-value of less than 0.05 (2tailed) were considered statistically significant.

Results
From March 2009 to October 2018, 727 medical students (M: F 387:340) completed the doctor-patient relationship and clinical communication skills course at PUMC. A total of 727 self-rating questionnaires were issued before the course, with 697 responses collected; 727 were issued at the end of the course, with 675 responses collected. A total of 651 students completed the questionnaire before and at the end of the course. With respect to curriculum evaluation, 727 questionnaires were distributed, with 675 responses received. Despite several verbal reminders, some of the students did not complete the survey (Table. 3).

Implementation process of the course
At the beginning of the course, many students thought that aim of doctor-patient communication was merely to reduce conflicts between doctors and patients. Our true aim is to help medical students understand the "human relationship" between doctor and patient, as Michael Balint famously said. Reducing conflict was just a natural part of that process.
Students are encouraged to understand the principles, basis and essence of doctor-patient relationship and communication after they finish their studies, and then apply these principles in medical practice. Clinical scenario drama is used as the main teaching method. In the beginning, instructional topics are as covered by the Calgary-Cambridge Guide, which include establishing a trusting doctor-patient relationship, collecting medical history information, explaining medical problems, breaking bad news, and negotiating treatment plan. Also, in accordance with situations in China, we added communication task with patient's family members. In total, seven themes emerged, including: Relationship building and empathy, obtaining patient psychosomatic history, explaining medical problems, negotiating treatment options, breaking bad news, coping with demanding patients, and communicating with relatives. In addition, case scripts were designed to make it in line with the Chinese context and cultural background (Table 1). During the years, students reported that they preferred clinical scenario dramas to lectures and thought they could gain more from practice. So, we adjusted the didactics with reduced lecture time (about 30 min per class). And a standardized operating procedure of role coaching was designed to guide all teachers ( Table 2).

Results of the self-rating questionnaires and curriculum evaluation
The majority of the study participants had significant improvements (p<0.05) in self-confidence regarding communication skills and professional practice, including relationship building, explaining medical problems, negotiating treatment options, breaking bad news, coping with demanding patients, communicating with  relatives when compared to pre-course evaluations and measurements (Table 4). Ratings for each subject before and after the course were analyzed using paired t-test, and the results were significantly different. The student curriculum evaluation results suggested that clinical scenario dramas were accepted and recognized for teaching doctor-patient communication skills compared to lectures (Table 5).

Discussion
We conducted courses on doctor-patient relationship and clinical communication skills for over 10 years at PUMC using clinical scenario drama techniques. Feedbacks from PUMC medical students indicated that subjectively, clinical scenario drama helped them to gain stronger confidence and better understand the doctorpatient relationship and improve their clinical communication skills, except for psychosomatic history taking. Few studies have explored the impact of doctors' low self-confidence in their ability to communicate. Selfconfidence affects cognition, emotion, intention and behavior in a wide range of ways [29]. When faced with stress and difficulties, people instinctively choose to use their more confident skills to cope. We have observed in clinical scenario drama that "doctors" are often more willing to use their medical knowledge and skills to persuade patients when confronted with contradictions and conflicts. The reasons why clinical scenario drama can improve the confidence of medical students in some tasks in doctor-patient communication may lie in: (1) Similar to social or psychodramas [30,31], clinical scenario dramas places medical students in situations felt by patients and their relatives. During these enactments, medical students become aware of the frustrations and challenges felt by their patients. The study participants played the role of patients, family members, or medical staff, so as to experience their attitudes, feelings, and emotions. In addition, the observer group had the opportunity to experience empathy and the highly emotional state of the patients. With regards to Ms. Liu's clinical scenario drama (Additional file 1), observers were exposed to the feelings behind the roles, the fear, the loneliness, and the helplessness. Uncovering these feelings and allowing them to be expressed is the goal of conducting these clinical scenario dramas. It is a powerful technique to help one "face one's demons" and is a key aspect for uncovering the unspoken thoughts and feelings that makes clinical communication challenging. In this regard, clinical scenario drama techniques are more effective compared to lectures as it helps improve empathy in medical staff. (2) As is known to all, the doctor-patient communication is a kind of procedural memory, need to be established in constant practice and mature. This kind of practical exercise can undoubtedly promote the confidence of the medical students in the use of various communication skills. Moreover, after receiving the feedback from observers, medical students still have the opportunity to try or observe the practice of other students, which provides the possibility of adopting different communication strategies in the same scene.
In this study, the students did not experience any improvement in their self-perception ability or confidence in taking psychosomatic medical histories. We found no previous studies that evaluated the benefits of drama techniques on psychosomatic history taking. However in 2017 [32], a German cohort study that was based on video-taped consultations gathered from year-four and graduating medical students indicated, on average, finalyear students scored higher in differential-diagnostic questioning and in-time management compared to their year-four counterparts. However, these final-year students showed deficiencies in basic communication skills and in interpreting and understanding patients' concerns, patient's perspectives and lacked empathy. In this study, there was no significant increase in medical students' self-confidence in taking psychosomatic history. The reason may be that the students have had previous training in medical history taking and have a certain level of confidence in this area. Through the study of doctor-patient relationship and communication, students realize that they still have shortcomings in this field. The results of this study also showed an improvement in their self-evaluations for active learning ability. Students felt that they could participate more actively, find solutions to problems, learn better in a team environment, gain insight from feedback and previous experiences. In addition, medical students were more interested in clinical scenario dramas compared to taking lectures. The students were highly satisfied with the course setting, teaching instructors and teaching content.
In reviewing the literature, we did not find any research on the perception and evaluation of drama technology among Chinese mainland medical students. Traditional Oriental culture and education mode are different from that of the West. In the field of medicine, they are more inclined to traditional family decision-making and pay more attention to the authority of doctors in doctor-patient relationship [33]. In the process of medical education, students are usually just recipients and teachers tell students what is right or wrong. The teaching principles of doctor-patient communication introduced from the West pay more attention to patient autonomy, emphasize patient-centered, and students' participation, experience, feedback and practice in the teaching process. It is doubtful whether such a concept and method can be accepted by medical students in mainland China. Our students' experience of clinical scenario drama was positive, according to the study. In such learning, medical students are not only "doctors", but also "patients", or "patients' families"; Not just the student, but the teacher, or the provider of feedback. In such a learning process, students not only acquire knowledge, but also experience and skills. As one student responded, "For learning medicine, the things out of medicine make a difference." There were several limitations to the current study. First of all, doctor-patient communication is a very complex process, and the existing evaluation methods in this study are not enough to objectively evaluate the impact of courses on students' actual communication ability. Secondly, there was a lack of control group in the study. Hence it is necessary to further evaluate the relationship between self-confidence and objective ability for doctorpatient communication skills of medical students.

Conclusion
This study introduced in detail the teaching methods for clinical scenario dramas and systematically evaluated these techniques for improving doctor-patient relationship and clinical communication skills of medical students. This is the first time a study of this nature has been conducted in mainland China. Our results showed that the clinical scenario dramas as a teaching method of doctor-patient relationship and the clinical communication skills, subjectively, enhance the medical students the confidence and the understanding of the various clinical communication task and compared with traditional teaching method, can increase the students' learning interest and initiative. However, its effect on clinical communication, still remains to be further verified.
