1. 2016–2020 topic modeling and topic categorization results
From January 1, 2016, to December 31, 2020, a total of 2,068 newspaper articles related to the competence and role of physicians were published: 378 in 2016, 294 in 2017, 371 in 2018, 432 in 2019, and 593 in 2020 (
Table 1). Topic modeling performed on these articles yielded 10 topics in 2016, nine topics in both 2017 and 2018, 11 topics in 2019, and 13 topics in 2020. When the topics identified through topic modeling shared similar keywords or themes, they were combined and categorized for each respective year. Consequently, eight topics were selected for 2016, seven for 2017, six for 2018, eight for 2019, and nine for 2020. The finalized topics were then assigned appropriate names.
The eight topics identified in 2016 were “digital healthcare,” “healthcare system,” “communicable disease control,” “medical technology,” “global healthcare,” “publicness in healthcare,” “medical volunteering,” and “patient safety.” The seven topics identified in 2017 were “patient safety,” “medical volunteering,” “publicness in healthcare,” “palliative care,” “convergence,” “healthcare system,” and “digital healthcare.” In 2018, the six topics were “digital healthcare,” “healthcare system,” “patient-centeredness and good doctors,” “publicness in healthcare,” “medical science research,” and “global healthcare.” In 2019, the eight topics were “digital healthcare,” “medical technology,” “publicness in healthcare,” “patient safety,” “global healthcare,” “healthcare policy,” “medical volunteering,” and “palliative care.” Finally, the nine topics that emerged in 2020 were “digital healthcare,” “publicness in healthcare,” “conflict between medical professionals and the government,” “COVID-19: telemedicine,” “telemedicine,” “medical volunteering,” “healthcare policy,” “COVID-19: lack of medical resources,” and “COVID-19: dedication of medical staff.”
As shown above, a total of 18 topics have been identified over the past 5 years. These topics are “digital healthcare,” “communicable disease control,” “medical technology,” “global healthcare,” “publicness in healthcare,” “medical volunteering,” “patient safety,” “palliative care,” “convergence,” “healthcare system,” “patient-centeredness and good doctors,” “medical science research,” “healthcare policy,” “conflict between medical professionals and the government,” “telemedicine,” “COVID-19: lack of medical resources,” “COVID-19: dedication of medical staff,” and “COVID-19: telemedicine.” Among these, “digital healthcare” and “publicness in healthcare” have been the most consistently discussed topics over the 5-year period. In contrast, certain topics emerged in specific years: “communicable disease control” appeared in 2016, “convergence” in 2017, “patient-centeredness and good doctors” and “medical science research” in 2018, and “conflict between medical professionals and the government,” “telemedicine,” “COVID-19: lack of medical resources,” “COVID-19: dedication of medical staff,” and “COVID-19: telemedicine” in 2020.
The 18 topics were grouped into four categories based on their similarities: healthcare industry, healthcare policy, patient-centered medicine, and infectious diseases. Specifically, the topics “digital healthcare,” “global healthcare,” “medical technology,” “convergence,” “medical science research,” and “telemedicine” were categorized under “healthcare industry.” The topics “publicness in healthcare,” “healthcare system,” “healthcare policy,” and “conflict between medical professionals and the government” were grouped under “healthcare policy.” The topics “medical volunteering,” “patient safety,” “palliative medicine,” “patient-centeredness,” and “good doctors” were classified as “patient-centered medicine.” Lastly, “communicable disease control,” “COVID-19: lack of medical resources,” “COVID-19: dedication of medical staff,” and “COVID-19: telemedicine” were categorized as “infectious diseases.”

3. Distribution of topics by year
The distribution of topics by year from 2016 to 2020 is presented in
Table 1. In 2016, the category with the highest number of newspaper articles was “medical technology,” accounting for 77 articles, or 20.4% of the total. The topic “communicable disease control” was unique to 2016, comprising 58 articles (15.3%) that were associated with the 2015 MERS outbreak. The concept of “publicness in healthcare” was consistently explored from 2016 to 2020, with key issues encompassing public healthcare, the creation of public medical schools, and the public health scholarship program. In terms of public healthcare, the government unveiled the Public Healthcare Implementation Plan and Public Healthcare Plan in 2016, followed by the Comprehensive Plan for the Development of Public Healthcare in 2018. These initiatives aimed to bolster national accountability for public healthcare and to mitigate regional disparities in access to essential medical services. Subsequently, media coverage highlighted these regional disparities, focusing on essential healthcare, public healthcare, and medical services. Notably, in 2018, articles pertaining to “publicness in healthcare” accounted for 18.1% of the total, a higher proportion than in other years. This surge can be attributed to the heightened coverage of conflicts between healthcare professionals and the government during that time. The government’s proposal to establish a national public medical college, intended to alleviate the workforce shortage in essential healthcare, was met with resistance from medical professionals, resulting in noteworthy discord.
Among the seven topics identified in 2017, “digital healthcare” (63, 21.4%) and “convergence” (59, 20.1%) had the highest proportions. Notably, the share of “digital healthcare” topics saw a significant increase of 6.3% points, rising from 15.1% in 2016 to 21.4% in 2017. This surge can be attributed to the deployment of the artificial intelligence system “Watson for Oncology” (Watson) by Gachon University Gil Hospital in December 2016, which spurred a substantial number of related articles the following year. Furthermore, the category of “convergence” emerged exclusively in 2017. This emergence is likely linked to the integration of Watson into digital healthcare, suggesting the potential for blending multidisciplinary care and collaboration, as well as merging medicine and information technology.
The topics “patient-centeredness and good doctors” (48 articles, 12.9%) and “medical science research” (36 articles, 9.7%) were only identified in 2018 and are associated with initiatives launched by the government that year. Specifically, the government announced the Patient-centered Medical Technology Optimization Research Project and the Strategy for Fostering Research Doctors and Hospital Innovation. It appears that articles related to these projects were prominently featured in 2018. Furthermore, there was a notable increase in articles pertaining to “global healthcare,” rising from 11.4% in 2016 to 21.0% in 2018. This surge can be seen as a response to a press release from the Ministry of Health and Welfare, which reported an uptick in the number of foreign patients visiting Korea in 2018.
“Palliative care” appeared as a topic in 2017 (28 cases, 9.5%) and 2019 (34 cases, 7.9%). These years correspond to significant legislative milestones in the realm of hospice and palliative care, as well as decisions regarding life-sustaining treatment for end-of-life patients. Specifically, a law was enacted on August 4, 2017, and subsequently underwent a partial amendment on March 28, 2019. This legislative activity likely accounts for the increased attention to palliative care in scholarly articles during 2017 and 2019.
In 2020, the landscape of healthcare and the challenges faced by doctors were unlike any other year. After the first case of COVID-19 was confirmed in South Korea, a continuous stream of issues related to the pandemic emerged. Additionally, there were significant disruptions such as collective leave taken by medical professionals due to disputes with the government, resident physician strikes, medical students jointly suspending their studies, and boycotts of the medical licensing examination. Consequently, the most prominent topics related to COVID-19 were “COVID-19: lack of medical resources” (97 mentions, 16.4%), “COVID-19: dedication of medical staff” (84 mentions, 14.2%), and “COVID-19: telemedicine” (86 mentions, 14.5%). These topics stood out in frequency when compared to other issues.
