Compared to the OECD average, the Korean population is relatively young and rate of behavioural risk factors relatively low. The system has, up until now, been focused on curative, rather than preventive care. However, rapid demographic shift, emerging risk factors linked to lifestyle, and an increasing burden of chronic diseases mean that prevention and public health should be a decisive policy priority sooner rather than later. The proportion of frail elderly is still low compared to OECD peers, with just 13.8% of the population over 65, and 3.0% over 80, in 2017. But Korea’s population is aging very rapidly, and by 2050 Korea is projected to have the largest over-65 population in the OECD, with 38% of people aged 65 years or over up from 13.8% in 2017, and 15.1% of the population 80 or over, up from 3.0% in 2017. While alcohol consumption and tobacco use are both slightly below the OECD average, and adult obesity is well below the OECD average, men are both heavy smokers and drinkers and child obesity rates are above the OECD average.
Following a dramatic increase over the past four decades, the average life expectancy in Korea is now 82.7 years, an increase of 8 years from 1977 to 2017. Non-communicable diseases account for the majority of Korea’s disease burden in Korea – the leading causes of mortality in Korea are cerebrovascular disease, Alzheimer disease, ischaemic heart disease, lung and liver cancer – although the prevalence of some infectious diseases – notably tuberculosis – remains high compared to OECD peers. A high rate of death by suicide also marks Korea out as an outlier, even as suicide rates have begun to fall in recent years.
Korea is also an outlier when it comes to health care consumption, with far higher rates of doctor consultations, an average 16.6 visits per population per year in 2017, than the OECD average of 6.8 in 2017. However, these health care consumption patterns do not necessarily support efforts to prevent disease or promote good health, as public health interventions are not prioritised during outpatient or hospital visits. Indeed, between 2000 and 2017, at a time when other OECD countries were shifting focus to care out of hospitals and reducing bed numbers, hospital bed numbers in Korea increased, and Korea had the second-highest number of hospital beds in 2017 with 12.3 beds per 1 000 population more than double the OECD average of 4.7 .
Korea relies on Public Health Centers to deliver some primary and preventive care, for example vaccinations, and relies on national campaigns and vertical prevention programmes to tackle unhealthy behaviours. To reduce smoking rates, Korea has introduced regulation limiting indoor smoking, increased the tobacco tax to 70% of the retail price in 2015, and introduced a warning image on tobacco products. Smoking cessation efforts are centralised, for example with national campaigns and some ‘Quit Smoking Centers’, although some programmes are also delivered at local public health centers. Targeted national programmes are also used to target other areas of public health, for example cancer screening is delivered through Korea’s National Cancer Screening Program, and there are some chronic disease management programmes being piloted, led by the Ministry of Health and Welfare. In the absence of a strong primary care system, Community Health Centers have, traditionally, been the main locus of non-communicable disease (NCD) management, and have sought to identify high-risk groups, but there is only one Center for every 300-500 000 population. In light of Korea’s aging population, and the current rate of risky health behaviour, strengthening primary care services, including disease prevention and early detection as well as chronic disease management, should be a priority, which could mean increasing the number of Community Health Centers, or equivalent service providers. Reducing child obesity – which is already above the OECD average – should also be a priority, with policy options including healthy meals in schools, educational programmes, and clear mandatory food labels especially on products targeted at children.
Harmful alcohol use is a key public health issue in Korea, especially for Korean men, who drink considerably more than the OECD average. Heavy episodic and high risk drinking are common and seem to be increasing; in Korea the average number of drinks consumed in one sitting has almost tripled in four years, from 2.2 cups in 2013 to 6.0 cups in 2016. Healthcare expenditure associated with alcohol use disorders also tripled between 2002 and 2013, from KRW 120 billion to KRW 375 billion (USD 101 million to USD 320 million), and it has been estimated that Korea faces KRW 1.0 trillion (USD 800 million) in medical expenses to treat conditions associated with alcohol use. Korea has already implemented a range of policies to try to reduce harmful alcohol consumption, for example running national awareness campaigns and targeted campaigns for instance in universities. However, there is significant scope for strengthening some of the Korea’s policies, and regulating alcohol availability. At present, relatively low prices of some alcoholic drinks like soju compared to other drinks, limited marketing restrictions, and few restrictions on points of sale make alcoholic beverages widely accessible. A comprehensive policy package is needed, strengthening some existing policies and introducing new efforts in other areas. Specifically, Korea should consider stronger advertising and sales restriction to reduce the normalisation of harmful alcohol consumption that occurs through constant exposure and availability, for example restricting billboard advertising and sales at petrol stations. Korea should also step-up education efforts in schools, universities and workplaces, and tweak alcohol pricing including reviewing existing policies across the full range of alcohol products.
The field of genomic medicine is booming and demand-driven by the population. Genomic research, large-scale genome genetic testing, genomic screening and diagnostic tests, personalised medicine, and direct-to-consumer genomic testing, are all significant areas of policy attention in Korea. There are, however, risks associated with the field of genomics, for example around the effective regulation of sensitive genetic information, ensuring equal access to cutting edge therapies, or ensuring that the use of genomics in health care is driven by the evidence-base, rather than potentially costly consumer or provider demand. When it comes to direct-to-consumer tests (DTC), ensuring that commercial tests do not expose consumers to inadvertent harm, and do not create additional strain to the health system, should be priorities, as should engaging the public in a discourse about risks and opportunities related to genetic testing.
In light of these risks, there are some further areas where governance of public health genomics should be strengthened. To maximise the potential positive impact of Korea’s extensive genomic research infrastructure for health care and public health interventions, capacity for data linkage between Korean biobank data and Health Insurance Review and Assessment Service (HIRA) or National Institute of Health (NIH) data systems could be facilitated. Regarding use of genomics by the health system, quality assurance for private testing laboratories should be introduced, and some basic training for health professionals in genomics would be a positive step. To anticipate potential demand for more personalised approaches to diagnosis and treatment, Korea should look to include cost-effectiveness assessments in deciding what tests should and should not be reimbursed. The area which generates the most concern when it comes to genomic medicine in Korea is the booming field of DTC genetic tests. At present, the Korean Government has been tightly regulating DTC use especially when linked to disease risk. This cautious approach is appropriate – and ought to be encouraged also when assessing whether or not to allow a further suite of DTC genetic tests for 13 diseases. When evaluating which DTC tests to allow, the Government should consider both potential impact on demand for health care – for instance follow up tests, or requests for (potentially unnecessary) treatment – as well as its capacity to give consumers enough information to responsibly interpret the results of their tests, and capacity for DTC companies to ensure data security and privacy. Overall, while genomic medicine may be a game changing force in health care in the decades to come, at present from a public health perspective ‘traditional’ approaches to preventing ill-health – such as regulation, education, screening and proactive disease managements – still have the strongest evidence-based.
Similarly to the shape of Korea’s population health risk profile, at first glance, Korea does not have a significant exposure to public health hazards and threats, but rather can be assessed as having a moderate exposure. However, just as a health system turned towards hospital-centric curative care will struggle in putting together a robust approach to preventing chronic disease and promoting good health, Korea’s risk and hazard system has – at least until recently – appeared ill-prepared for major crises. Indeed, the 2014 Sewol Ferry accident and the 2015 Middle East Respiratory Syndrome Coronavirus (MERS-CoV) in Korea revealed important shortcomings in public health emergency preparedness and response, causing significant human losses and a large disarray within Korea society. Since these events, public health emergency preparedness has become a priority in Korea, and the government has engaged in important reforms. Specifically, legal and institutional frameworks have been revised, investments have been made to reinforce emergency preparedness capabilities across the board, and Korea is using innovative technological approaches to timely detection, enable information-sharing from authorities to citizens, and facilitate decision-making.
Despite the usefulness of these necessary policy reforms, and Korea’s new capabilities in the area of public health emergencies, there is still more work to be done. While the steps taken to ensure that the Ministry of Interior and Safety (MOIS) now centrally coordinates all emergency preparedness and response capacities, with a dedicated Vice Minister, seems to be a positive step, it could be further strengthened by introducing greater clarity over the different responsibilities of local governments, and their expected response when emergencies unfold. Equally, somewhat streamlining the expectations of stakeholders when it comes to developing emergency response plans – currently Korea has nearly 3 000 different crisis response manuals – would make it easier for key actors to understand their responsibilities, and create greater coherence in response when crises occur. Undertaking regular multi-stakeholders emergency simulation exercises based on complex scenarios would also be a valuable additional way to prepare all actors, including helping actors to work well together. At present, simple exercises and drills are performed regularly, but may not be sufficient to prepare for complex, unpredictable, and fast-moving emergency situations. Korea should also take advantage of its rich information-base on risk and emergencies to conduct a whole-of-government scenario-based National Risk Assessment. Many OECD countries conduct such an assessment, which helps to anticipate scenarios based on greatest likelihood and potential impact, and allocate resources accordingly.
