Practice patterns of multidisciplinary team meetings in Korean cancer care and patient satisfaction with this approach
Article information
Abstract
Background/Aims
The multidisciplinary team (MDT) approach is a cornerstone of clinical oncology. This study investigated the current state of MDT care, including patient satisfaction, in Korea.
Methods
We obtained the annual number of cancer patients who have received MDT care since 2014 from the registry of the Health Insurance Review and Assessment Service (HIRA). In addition, patients who received MDT care from August 2014 to May 2017 at four university hospitals were further characterized, and patient satisfaction was measured prospectively using a patient-reported questionnaire.
Results
The total number of patients who received MDT care increased from 2014 to 2016 (2,113 to 9,998 patients, respectively) in the HIRA Cohort. The type of cancer that most often required MDT was breast cancer (23.8%), followed by colorectal cancer (19.1%). In the Representative Cohort (n = 1,032), MDT was requested by the surgeon more than half the time (55.7%). The main focus of MDT was decision making for further treatment planning (99.0%). The number of doctors participating in the MDT was usually five (70.0%). After initiating an MDT approach, the treatment plan changed for 17.4% of patients. Among these patients, 359 completed a prospective satisfaction survey regarding their MDT care. The overall satisfaction with the MDT approach was very high, with an average score of 9.6 out of 10 points.
Conclusions
The application of MDT care is a rapidly growing trend in clinical oncology, and shows high patient satisfaction. Further research is needed to determine which types of cancer patients could benefit most from MDT, and to enable MDT care to operate more efficiently so that it may expand successfully throughout Korea.
INTRODUCTION
Clinical treatment decisions for cancer patients often vary among physicians [1]. This is due to a wide variety of patient clinical presentations and the fragmented subspecialties among cancer specialists. In addition, these hurdles may lead to a substantial number of cancer patients seeking a second opinion [2]. Given the complexity of cancer care, the multidisciplinary team (MDT) approach is a cornerstone of optimal management. This is supported by international trends in that MDT care is mandatory in 63% of European countries and national or state-defined guidelines for the use of MDT have been implemented in the United Kingdom (UK) [3,4]. Furthermore, a policy statement on MDT cancer care has been released by The European Partnership for Action Against Cancer to help each individual institute establish a qualified MDT [5].
Several studies have reported that MDT-based decision making has led to changes in initial diagnoses and treatment plans, more accurate diagnoses, and even improved survival outcomes [6-9]. In Korea, the implementation of MDT care and its role in certain cancers, such as colorectal and gynecologic cancers, has been explored [10,11]. As shown by these data, MDT care has been actively adopted. However, these previous reports were single-center studies that focused mainly on the impact of MDT care on clinical decision making, defined as the rate of change in the treatment plan or diagnosis.
MDT-based decision making for cancer patients in Korea has been officially introduced and encouraged by the National Health Insurance Service (NHIS) since August 2014. According to a subsequent study concerning MDT care for cancer patients in Korea [12], the application of MDT care after reimbursement appears to be successful. However, this study was conducted within the first 6 months of reimbursement, which is too early to assess the overall trend for MDT care since its inception. Meanwhile, another study conducted by medical oncologists demonstrated that the proportion of MDTs involved in cancer care was less than 10%. When limited to the four major types of cancer (lung, breast, stomach, and colorectal), the rate was still only 20% to 30% [13]. However, the results of that study were based on a cross-sectional survey conducted over a transient period, rather than over a sufficiently long period. Furthermore, studies that address satisfaction with MDT care from the perspective of the patient rather than the physician have not yet been reported worldwide [8]. Patient’s attendance is a prerequisite for reimbursement from the NHIS, so it is important that MDT work efficiently from the patient’s perspective. Taken together, no study has yet investigated the trends, overall implementation, and patient satisfaction with MDT care since reimbursement for MDT care began in Korea. In this study, we aimed to investigate the increasing trend of MDT care in clinical oncology and to examine the clinical characteristics as well as the satisfaction of cancer patients receiving MDT care in Korea.
METHODS
Patients
This study involved two cohorts. First, the annual number of cancer patients who received MDT care in Korea was obtained from the registry of the Health Insurance Review and Assessment Service (HIRA), and these patients made up the HIRA cohort. Because all cancer patients receiving MDT care in Korea have been registered in the HIRA system since August 2014, upon implementation of reimbursement for MDT care, the distribution of patients by cancer type, region, age, sex, and the total number of patients since that time can be viewed. Second, we selected four university hospitals in Korea to analyze the clinical characteristics, details of MDT care, and satisfaction with MDT care of patients in real-world practice; these patients made up the Representative Cohort. These four hospitals were selected from among the institutions that members of the Insurance and Policy Committee of Korean Society of Medical Oncology are affiliated.
Analysis of the Representative Cohort consisted of two parts. First, demographic findings and clinical characteristics, including stage, cancer type, and treatment history, were collected from August 2014 to May 2017. The detailed characteristics of MDT care included the number of attending physicians, time expended by the MDT, the patient’s accompanying family members, and the aim of each MDT. For a portion of the patients, a survey on the patient’s satisfaction with MDT care was conducted prospectively from September 2016 to May 2017. After leaving the care of the MDT, each subject was administered the questionnaire and allowed to respond. The protocol for the study was reviewed and approved by the Institutional Review Board (IRB) of each participating institute (Approval Number: KHUH 2016-10-047 in Kyung Hee University Hospital, Kyung Hee University School of Medicine; GBIRB2016-303 in Gachon University Gil Medical Center; CR317013 in Wonju Severance Christian Hospital, Yonsei University Wonju College of Medicine; 2016-99 in Dongguk University Ilsan Hospital; a waiver of approval was granted at the last hospital). Patients provided written informed or verbal consent according to the approval of the IRB and this study complied with the Declaration of Helsinki.
Questionnaire
Patient satisfaction with MDT care was measured by a simple questionnaire containing 10 key questions about personal satisfaction. The key questions were as follows: (1) Is this the first time you have received MDT care?; (2) Did you have enough time to discuss with the doctors?; (3) Was the process of receiving MDT care easy and straightforward?; (4) Did the doctors who attended the MDT care provide easy and comprehensible explanations?; (5) Did the doctors listen carefully to your words?; (6) Did the doctors provide a sincere and satisfactory answer to your question?; (7) Did your confidence in the management plan of the doctors change after MDT care?; (8) What differences do you find compared with visits delivered by individual departments?; (9) What do you think should be improved in MDT care?; (10) How many points on a 10-point scale would you give for your MDT care? Questionnaire items 2 to 7, pertaining to the subjective opinion of the patient, were answered semi-quantitatively by one of four options on a graded scale, whereas items 8 and 9 were answered freely.
RESULTS
Trend of MDT care
The HIRA cohort comprised patients treated by two MDT types based on the number of doctors who participated (four-department participation and five-department participation types) depending on the insurance claim. There was a time gap in the statistical work of the HIRA database. Thus, the data search for our study was possible up to December 2016. The four-department participation type comprised 525 cases in August 2014, when the Korean government began reimbursing MDT care. The case number increased to 2,468 and 3,031 in 2015 and 2016, respectively, showing a rapid and continuous increase the following year (Fig. 1A). The most common age group was between 60 and 69 years in 2016 (Fig. 1B). The five-department participation type showed a similar pattern. The case numbers also rapidly increased to 1,699, 7,815, and 8,143 in 2014, 2015, and 2016, respectively (Fig. 1A). The largest age group in 2016 was 50 to 59 years (Fig. 1C). The number of cases by region was highest in Seoul, followed by Gyeonggi-do. The most common type of cancer during this period was breast cancer (23.8%, 3,640/15,283) followed by colorectal (19.1%), lung (12.0%), and stomach (7.4%) cancers, which corresponded to incidences, according to the annual cancer statistics of Korea in 2015 [14], of 18.9% (3,640/19,219), 10.9% (2,923/26,790), 7.5% (1,831/24,267), and 3.8% (1,124/29,207), respectively.

Characteristics of MDT
For a more detailed characterization of patients and MDT care, we collected and analyzed information from the Representative Cohort. The total number of registered patients was 1,032. Among these patients, 359 completed a prospective survey of patient satisfaction with MDT care. The patients’ social and clinical information is detailed in Table 1. The patients were mostly married with a good performance status. Of 365 patients with available information on MDT care attendance, 85% (312/365) participated in MDT cares with a family member, such as their spouse, offspring, or parent, suggesting that family support is an important value in Korea. MDT care was requested mainly by the surgery department, including breast and gastrointestinal surgeons, a finding consistent with the size of this department in the HIRA cohort. The aims of MDT care were mainly deciding further treatment planning (99.7%) and explaining the disease status and predicting prognosis (33.5%). The actual number of doctors who participated ranged from four to eight, with five being the most common (70.0%). The time required for MDT-based decision making was typically 10 to 30 minutes, although some cases lasted more than 30 minutes (0.3%). The final decision made based on MDT care led to a change in the management plan for 17.4% of patients (Table 2).

Satisfaction with MDT care
The responses to the survey are summarized in Table 3. The overall satisfaction with MDT care was very high, according to the responses to all questions, including sufficient time provided to discuss the treatment plan with the MDT, easy accessibility and explanation by the MDT, careful attention to the patient’s concerns, satisfactory answers to the patient’s questions, and trusting the health professionals involved in MDT care. The mean satisfaction score based on a scale of 0 to 10 was 9.6. The answers to items 8 and 9, which were required to describe the subjective opinion were summarized separately (Supplementary Table 1).

DISCUSSION
Our findings showed that the frequency of using MDT care has increased rapidly since reimbursement for MDT care by the NHIS began. In addition, we found that MDT care is operating very well and produces high levels of satisfaction from patient perspectives. The clinical presentation of cancer patients varies greatly from individual to individual. Thus, cancer care is often very complex and challenging to many doctors. Various clinical guidelines have been developed to help and guide optimal decision making for oncologists. However, some guidelines have proven to be untrustworthy after critical review [15]. Furthermore, standard guidelines often cannot be applied to cancer patients with atypical clinical features. Both evidence-based principles and expert-opinion-based practice are needed to achieve optimal decision making [16].
According to a report by the National Cancer Action Team in the UK regarding the characteristics of effective cancer treatment, MDT is beneficial for all cancer types [3]. This was supported by a study showing strong agreement between MDT members who participated in the management of different types of tumors [17]. Over 80% of all patients with cancer in the UK are managed by MDTs [18]; however, our study showed that less than approximately 20% of cancer patients in Korea have received MDT care, suggesting that MDT implementation is still in its infancy in Korea. Moreover, the frequency of MDT care in Korea varied by region (being most frequent in Seoul), which could be because of the increased number of university hospitals located in the metropolitan area. On the other hand, there is still doubt concerning which patients would benefit from MDT care. It has been shown that, although many doctors prefer to meet most of their new patients as an MDT, it is not always necessary, especially for early stage or low-risk patients [19,20]. Unlike other counties, MDT care in Korea is characterized by the fact that the patient must attend the meeting with his or her doctors [20,21]. In addition, much administrative effort is required to coordinate the schedule of multiple doctors and participating patients. Therefore, to make MDT care as efficient and successful as possible, it is essential to administer the physicians’ limited time to patients who will benefit the most from an MDT approach.
Based on the survey conducted in the Representative Cohort, the primary aim of MDT care was to devise a management plan for a given clinical situation. It was found that the diagnosis and/or management plan often changes after MDT care for a substantial proportion of patients. According to some studies, 12% to 38% of patients experienced a change in their diagnosis or management plan after MDT care [22-26]. However, the rate of such a change was less than 10% [27-29] or even negligible [30] in other reports. In our study, the rate of change was 17.4%, which was consistent with previous studies but slightly lower than we expected. This could be explained by the smaller proportion of newly diagnosed patients who underwent MDT care. In our study, 70.3% of patients received at least one type of treatment before MDT care, compared with 29.7% who did not. It was assumed that this 29.7% of patients received MDT care at the time of initial diagnosis. Considering that MDT care at the time of initial diagnosis usually leads to a substantial change in the treatment plan as a result of a revised preoperative stage or histologic results [22,29,31- 33], the small proportion of newly diagnosed patients in our cohort may explain the relatively low rate of change in the treatment plan after MDT care.
Further support for providing MDT care came from the ability to provide a detailed explanation to the patient regarding their disease status (19% of all respondents). Some respondents reported that it was easier to accept and understand the doctors’ explanation because the MDT members worked together to discuss with the patient. Because MDT care is usually requested when a patient’s disease status has drastically changed or worsened, such as recurrence detected during a regular follow-up, the patient often does not trust the doctor’s diagnosis or occasionally seeks a second opinion rather than accept the bad news. Thus, it may be assumed that delivering bad news is easier when conducted by several doctors together. Many researchers have consistently reported that MDT care is necessary and helpful in communicating bad news [34-37]. Additionally, Korean MDTs should involve the patient and/or their family because of reimbursement indications, whereas MDTs in the UK rarely invite the patient because of concerns regarding the inability to speak frankly about the prognosis and because of time constraints [38]. However, considering that the purpose of MDT care is not only for effective decision making but also for easier communication between the patient and physician, MDT care involving patient participation may be better than that not involving the patient. If patients do not participate in the MDT, the meeting is typically similar to a tumor board, where doctors discuss the clinical case without the patient. In this way, it is possible to discuss many cases quickly in a short period of time, but establishing a treatment plan without considering the patients’ preferences and individual circumstances or addressing their concerns may decreases patient satisfaction.
According to the prospective survey, the overall satisfaction of cancer patients in Korea receiving MDT care was substantially high. As shown in Table 3, most patients responded that there was sufficient time to discuss with the MDT, easy accessibility to the MDT, careful attention to the patient’s concerns and satisfactory answers to the patient’s questions by the MDT, and trust of the health professionals in the MDT. The patient’s perception of the doctor’s empathy and the time allotted to discuss with the doctors showed a positive correlation with the patient’s satisfaction [39,40]. In our study, the time allotted for discussion between the patient and MDT was approximately 20 minutes, which was thought to be sufficient.
When MDT care was first introduced in Korea in 2014, the NHIS provided reimbursement only for MDT care given to outpatients by doctors from at least four or five departments. This contrasted with the European guideline “Policy statement on multidisciplinary cancer care” released to help local institutes establish and implement optimal MDT care [5].
Fortunately, reimbursement for MDT care has been expanded to inpatients as well as MDTs consisting of doctors from only three departments, suggesting encouragement of MDT care by the Korean government. Meanwhile, a recent European MDT policy statement mentioned the importance of psychosocial support in addition to diagnosis and treatment, which emphasized the role of psychiatrists in an MDT [5]. However, our survey showed that no patient received MDT care involving a psychosocial specialist. Likewise, discussion of survival and/or a palliative care team should also be incorporated into MDT care, but such incorporation was also not observed in our survey.
Our study had several limitations. Whether the four hospitals included in the Representative Cohort sufficiently reflected the entire status of MDT care in Korea is debatable considering selection bias. Second, there was a substantial amount of missing data, including the relationships between the patient and involved family members, number of family members receiving MDT care, Eastern Cooperative Oncology Group (ECOG) performance status, and the period of MDT care.
In conclusion, the application of MDT care for cancer patients in Korea has grown rapidly since reimbursement for MDT care by the NHIS began. The format for MDT care in Korea is patient-centered with prominent family support, and patient satisfaction was generally excellent. Further research is needed to determine which patients can gain the most benefit from a MDTbased treatment approach to make MDT more efficient and help it to expand successfully in Korea.
